Factor XI inhibitor–based anticoagulation strategies gain ground
according to Jeffrey I. Weitz, MD.
These strategies could pick up where direct-acting oral anticoagulants leave off, he suggested during a presentation at the biennial summit of the Thrombosis & Hemostasis Societies of North America.
“We all know that the direct oral anticoagulants – the DOACs – are an advance over vitamin K antagonists,” said Dr. Weitz, professor of medicine and biochemistry at McMaster University, Hamilton, Ontario.
Not only are DOACs at least as effective as vitamin K antagonists such as warfarin for stroke prevention in atrial fibrillation or for treatment of venous thromboembolism (VTE), but they also reduce intracranial bleeding and major bleeding risk in those settings, respectively, and they are more convenient to administer because they can be delivered using fixed doses without the need for coagulation monitoring, he added.
Still, new targets are needed, he said, explaining that, although DOACs moved closer to the goal of attenuating thrombosis without increasing the risk of bleeding, annual rates of major bleeding remain at 2%-3% in the atrial fibrillation population, and rates of major and clinically relevant nonmajor bleeding are about 10%.
“The fear of bleeding leads to underuse of anticoagulants for eligible patients with atrial fibrillation and inappropriate use of low-dose [non–vitamin K antagonist oral anticoagulant] regimens, which can leave patients unprotected from thrombotic complications,” he said.
Factor XI
That’s where Factor XI (FXI) may come in, Dr. Weitz said.
Current anticoagulants target enzymes, including FXa or thrombin, in the common pathway of coagulation, but the intrinsic pathway at the level of FXI and FXII has attracted attention in recent years.
The intrinsic pathway is activated when blood comes into contact with medical devices like stents, mechanical heart valves, or central venous catheters, but evidence also suggests that it plays a role in clot stabilization and growth, he explained, noting additional evidence of attenuation of thrombosis in mice deficient in FXI or FXII and in animals with FXI or FXII inhibitors.
“There is no bleeding with congenital FXII deficiency, and patients with FXI deficiency rarely have spontaneous bleeding, although they can bleed with surgery or trauma,” he noted. “Therefore, the promise of contact pathway inhibition is that we can attenuate thrombosis with little or no disruption of hemostasis.”
The initiators of the intrinsic pathway are naturally occurring polyphosphates that can activate FXI and FXII, promote platelet activation, and lead to thrombosis. A number of agents are being investigated to target these enzymes – particularly FXI, for which the strongest epidemiological and other evidence of its link with thrombosis exists. He noted that FXI deficiency appears protective against deep-vein thrombosis (DVT) and ischemic stroke, whereas high levels are linked with an increased risk of venous and arterial thrombosis.
Investigative strategies include the use of antisense oligonucleotides to reduce hepatic synthesis of FXI, aptamers to bind FXI and block its activity, antibodies to bind FXI and block its activation or activity, and small molecules to bind reversibly to the active site of FXI and block its activity “much like the DOACs block the activity of FXa or thrombin.”
“We have to remember that the DOACs have taken over from vitamin K antagonists, like warfarin, for many indications, and as they go generic their uptake will increase even further,” Dr. Weitz said. “When we compare the FXI inhibitors with existing anticoagulants, we don’t necessarily want to go up against the DOACs – we’re looking for indications where [DOACs] have yet to be tested or may be unsafe.”
Potential indications include the following:
Prevention of major adverse cardiovascular events in patients with end-stage renal disease with or without atrial fibrillation.
Provision of a safer platform for antiplatelet therapy in patients with acute coronary syndrome.
Secondary stroke prevention.
Prevention or treatment of cancer-associated VTE.
Prevention of thrombosis associated with central venous catheters, left ventricular assist devices, or mechanical heart valves.
Agents in development
Of the FXI inhibitors in development, ISIS-FXIRx, an antisense oligonucleotide against FXI, is furthest along. In a study published in Blood, ISIS-FXIRx produced a dose-dependent and sustained reduction in FXI levels in healthy volunteers, and in a later randomized study published in The New England Journal of Medicine, it significantly reduced the incidence of DVT in patients undergoing voluntary total knee arthroplasty (30.4% with enoxaparin vs. 4.2% with ISIS-FXIRx at a dose of 300 mg). Bleeding rates were 8.3% and 2.6%, respectively.
The findings showed the potential for reducing thrombosis without increasing bleeding by targeting FXI, Dr. Weitz said, adding that ISIS-FXIRx was also evaluated in a small study of patients with end-stage renal disease undergoing hemodialysis and was shown to produce a dose-dependent reduction in FXI levels and to reduce the incidence of category 3 and 4 clotting in the air trap and dialyzer, compared with placebo, when given in addition to heparin.
This suggests that FXI knockdown can attenuate device-associated clotting to a greater extent than heparin alone, Dr. Weitz said.
The FXIa-directed inhibitory antibody osocimab has also been evaluated in both healthy volunteers and in patients undergoing total knee arthroplasty. In a 2019 study of healthy volunteers, a single IV injection showed a dose-dependent pharmacokinetic profile and produced FXI inhibition for about 1 month, and in the FOXTROT trial published in January in JAMA by Dr. Weitz and colleagues, osocimab was shown to reduce the incidence of symptomatic VTE, asymptomatic DVT, and VTE-related death up to day 10-13 after total knee arthroplasty.
Osocimab at doses ranging from 0.3-1.8 mg/kg given postoperatively or preoperatively were noninferior to enoxaparin (rates of 15.7%-23.7% vs. 26.3%), and osocimab at a preoperative dose of 1.8 mg/kg was superior to both enoxaparin and apixaban (11.5% vs. 26.3% and 14.5%, respectively), he said.
Bleeding rates ranged from 0%-5% with osocimab, compared with 6% with enoxaparin and 2% with apixaban
Ongoing studies
Currently ongoing studies of FXI-directed anticoagulation strategies include a study comparing ISIS-FXIRx with placebo in 200 patients with end-stage renal disease, a study comparing osocimab with placebo in 600 patients with end-stage renal disease, and a study comparing abelacimab – an antibody that binds to FXI and prevents its activation by either FXIIa or thrombin, with enoxaparin in 700 patients undergoing total knee arthroplasty, Dr. Weitz said.
Additionally, there is “considerable activity” with small molecule inhibitors of FXIa, including a phase 2, placebo-controlled, dose-ranging study looking at the novel JNG-7003/BMS-986177 agent for secondary stroke/transient ischemic attack prevention in 2,500 patients and a phase 2 study comparing it with enoxaparin for postoperative thromboprophylaxis in 1,200 patients undergoing total knee arthroplasty.
Parallel phase 2 studies are also underway to compare the novel BAY-2433334 small molecule inhibitor with placebo for stroke/transient ischemic attack prevention, with apixaban for atrial fibrillation, and for prevention of major adverse cardiovascular events in patients with acute MI.
These ongoing trials will help determine the risk-benefit profile of FXI inhibitors he said.
Session comoderator Anne Rose, PharmD, pharmacy coordinator at the University of Wisconsin, Madison, noted that these types of agents have been discussed “for quite some time” and asked whether they will be available for use in clinical practice in the near future.
Dr. Weitz predicted it will be at least a few years. The studies are just now moving to phase 2b and will still need to be evaluated in phase 3 trials and for appropriate new indications, he said.
Dr. Weitz reported research support from Canadian Institutes of Health research, Heart and Stroke Foundation, and Canadian Fund for Innovation, and he is a consultant and/or scientific advisory board member for Anthos, Bayer, Boehringer-Ingelheim, Bristol-Myers Squibb, Daiichi-Sankyo, Ionis Pharmaceuticals, Janssen, Merck, Novartis, Pfizer, Portola, Servier , and Thetherex.

FROM THE THSNA BIENNIAL SUMMIT
Metapneumovirus infections clinically indistinguishable from flu, RSV
The all-consuming news about SARS-CoV-2 and COVID-19 has overshadowed other viral pathogens that are the cause of severe or fatal lower respiratory infections (LRI) including human metapneumovirus (HMPV).
“MPV is really a leading cause of LRI not just in children but in adults, with high mortality rates in the frail elderly, long-term care facilities, and cancer patients with pneumonia, “ said John Williams, MD, from the department of pediatric infectious diseases at the University of Pittsburgh Medical Center.
“Right now we have no effective antivirals. There are monoclonal antibodies in development that my group and others have discovered. In fact, some of these treat MPV and RSV [respiratory syncytial virus], so we may have good options,” he said in an online presentation during an annual scientific meeting on infectious diseases.
The virus preys, wolf-like, on the most vulnerable patients, including children and frail elderly adults, as well as other adults with predisposing conditions, he said.
HMPV causes acute respiratory illnesses in approximately 2%-11% of hospitalized adults, 3%-25% of organ transplant recipients or cancer patients, 4%-12% of chronic obstructive pulmonary disease exacerbations, 5%-20% of asthma exacerbations, and it has been identified in multiple outbreaks at long-term care facilities.
Relative newcomer
Metapneumovirus was isolated and discovered from children with respiratory tract disease in the early 2000s. Once included in the family of paramyxoviruses (including measles, mumps, Nipah virus, and parainfluenza virus 1-4), HMPV and RSV are now classified as pneumoviruses, based on gene order and other characteristics, Dr. Williams explained.
Various studies have consistently placed the prevalence of HMPV ranging from 5%-14% in young children with LRI, children hospitalized for wheezing, adults with cancer and LRI, adults with asthma admissions, children with upper respiratory infections, and children hospitalized in the United States and Jordan for LRI, as well as children hospitalized in the United States and Peru with acute respiratory infections.
A study tracking respiratory infections in a Rochester, N.Y., cohort from 1999 through 2003 showed that healthy elderly patients had and annual incidence of HMPV infections of 5.9%, compared with 9.1% for high-risk patients, 13.1% for young patients, and 8.5% among hospitalized adult patients.
“These percentages are virtually identical to what has been seen in the same cohort for respiratory syncytial virus, so in this multiyear prospective cohort, metapneumovirus was as common as RSV,” Dr. Williams said.
Although the incidences of both HMPV and RSV were lower among hospitalized adults “clinically, we can’t tell these respiratory viruses apart. If we know it’s circulating we can make a guess, but we really can’t discriminate them,” he added.
In the Rochester cohort the frequency of clinical symptoms – including congestion, sore throat, cough, sputum production, dyspnea, and fever – were similar among patients infected with HMPV, RSV, or influenza A, with the exception of a slightly higher incidence of wheezing (80%) with HMPV, compared with influenza.
“I can tell you as a pediatrician, this is absolutely true in children, that metapneumovirus is indistinguishable from other respiratory viruses in kids,” he said.
Fatalities among older adults
As noted before, HMPV can cause severe and fatal illness in adults. For example, during an outbreak in North Dakota in 2016, 3 of 27 hospitalized adults with HMPV (median age, 69 years) died, and 10 required mechanical or noninvasive ventilation.
In a study from Korea comparing outcomes of severe HMPV-associated community-acquired pneumonia (CAP) with those of severe influenza-associated CAP, the investigators found that 30- and 60-day mortality rates were similar between the groups, at 24% of patients with HMPV-associated CAP and 32.1% for influenza-associated CAP, and 32% versus 38.5%, respectively.
Patients at high risk for severe disease or death from HMPV infection include those over 65 years, especially frail elderly, patients with chronic obstructive pulmonary disease, immunocompromised patients, and those with cardiopulmonary diseases such as congestive heart failure.
Supportive care only
“Do we have anything for treatment? The short answer is, No,” Dr. Williams.
Supportive care is currently the only effective approach for patients with severe HMPV infection.
Ribavirin, used to treat patients with acute RSV infection, has poor in vitro activity against HMPV and poor oral bioavailability and hemolysis, and there are no randomized controlled trials to support its use in this situation.
“It really can’t be recommended, and I don’t recommend it,” he said.
Virology may still help
Mark J. Siedner, MD, an infectious diseases physician at Mass General and associate professor of medicine at Harvard Medical School, both in Boston, who was not involved in the study, said that, despite the inability to clinically distinguish HMPV from RSV or influenza A, there is still clinical value to identifying HMPV infections.
“We spend millions of dollar each year treating people for upper respiratory tract infections, often with antibacterials, sometimes with antivirals, but those have costs to the health care system, and they also have costs in terms of drug resistance,” he said in an interview seeking objective commentary.
“Diagnostic tests that determine the actual source or the cause of these upper respiratory tract infections and encourage both patients and physicians not to be using antibiotics have value,” he said.
Identifying the pathogen can also help clinicians take appropriate infection-control precautions to prevent patient-to-clinician or patient-to-patient transmission of viral infections, he added.
Dr. Williams’ research is supported by the National Institutes of Health, Henry L. Hillman Foundation, and Asher Krop Memorial Fund of Children’s Hospital of Pittsburgh. Dr. Williams and Dr. Siedner reported no relevant conflict of interest disclosures.

“It really can’t be recommended, and I don’t recommend it,” he said.
Virology may still help
Mark J. Siedner, MD, an infectious diseases physician at Mass General and associate professor of medicine at Harvard Medical School, both in Boston, who was not involved in the study, said that, despite the inability to clinically distinguish HMPV from RSV or influenza A, there is still clinical value to identifying HMPV infections.
“We spend millions of dollar each year treating people for upper respiratory tract infections, often with antibacterials, sometimes with antivirals, but those have costs to the health care system, and they also have costs in terms of drug resistance,” he said in an interview seeking objective commentary.
“Diagnostic tests that determine the actual source or the cause of these upper respiratory tract infections and encourage both patients and physicians not to be using antibiotics have value,” he said.
Identifying the pathogen can also help clinicians take appropriate infection-control precautions to prevent patient-to-clinician or patient-to-patient transmission of viral infections, he added.
Dr. Williams’ research is supported by the National Institutes of Health, Henry L. Hillman Foundation, and Asher Krop Memorial Fund of Children’s Hospital of Pittsburgh. Dr. Williams and Dr. Siedner reported no relevant conflict of interest disclosures.
The all-consuming news about SARS-CoV-2 and COVID-19 has overshadowed other viral pathogens that are the cause of severe or fatal lower respiratory infections (LRI) including human metapneumovirus (HMPV).
“MPV is really a leading cause of LRI not just in children but in adults, with high mortality rates in the frail elderly, long-term care facilities, and cancer patients with pneumonia, “ said John Williams, MD, from the department of pediatric infectious diseases at the University of Pittsburgh Medical Center.
“Right now we have no effective antivirals. There are monoclonal antibodies in development that my group and others have discovered. In fact, some of these treat MPV and RSV [respiratory syncytial virus], so we may have good options,” he said in an online presentation during an annual scientific meeting on infectious diseases.
The virus preys, wolf-like, on the most vulnerable patients, including children and frail elderly adults, as well as other adults with predisposing conditions, he said.
HMPV causes acute respiratory illnesses in approximately 2%-11% of hospitalized adults, 3%-25% of organ transplant recipients or cancer patients, 4%-12% of chronic obstructive pulmonary disease exacerbations, 5%-20% of asthma exacerbations, and it has been identified in multiple outbreaks at long-term care facilities.
Relative newcomer
Metapneumovirus was isolated and discovered from children with respiratory tract disease in the early 2000s. Once included in the family of paramyxoviruses (including measles, mumps, Nipah virus, and parainfluenza virus 1-4), HMPV and RSV are now classified as pneumoviruses, based on gene order and other characteristics, Dr. Williams explained.
Various studies have consistently placed the prevalence of HMPV ranging from 5%-14% in young children with LRI, children hospitalized for wheezing, adults with cancer and LRI, adults with asthma admissions, children with upper respiratory infections, and children hospitalized in the United States and Jordan for LRI, as well as children hospitalized in the United States and Peru with acute respiratory infections.
A study tracking respiratory infections in a Rochester, N.Y., cohort from 1999 through 2003 showed that healthy elderly patients had and annual incidence of HMPV infections of 5.9%, compared with 9.1% for high-risk patients, 13.1% for young patients, and 8.5% among hospitalized adult patients.
“These percentages are virtually identical to what has been seen in the same cohort for respiratory syncytial virus, so in this multiyear prospective cohort, metapneumovirus was as common as RSV,” Dr. Williams said.
Although the incidences of both HMPV and RSV were lower among hospitalized adults “clinically, we can’t tell these respiratory viruses apart. If we know it’s circulating we can make a guess, but we really can’t discriminate them,” he added.
In the Rochester cohort the frequency of clinical symptoms – including congestion, sore throat, cough, sputum production, dyspnea, and fever – were similar among patients infected with HMPV, RSV, or influenza A, with the exception of a slightly higher incidence of wheezing (80%) with HMPV, compared with influenza.
“I can tell you as a pediatrician, this is absolutely true in children, that metapneumovirus is indistinguishable from other respiratory viruses in kids,” he said.
Fatalities among older adults
As noted before, HMPV can cause severe and fatal illness in adults. For example, during an outbreak in North Dakota in 2016, 3 of 27 hospitalized adults with HMPV (median age, 69 years) died, and 10 required mechanical or noninvasive ventilation.
In a study from Korea comparing outcomes of severe HMPV-associated community-acquired pneumonia (CAP) with those of severe influenza-associated CAP, the investigators found that 30- and 60-day mortality rates were similar between the groups, at 24% of patients with HMPV-associated CAP and 32.1% for influenza-associated CAP, and 32% versus 38.5%, respectively.
Patients at high risk for severe disease or death from HMPV infection include those over 65 years, especially frail elderly, patients with chronic obstructive pulmonary disease, immunocompromised patients, and those with cardiopulmonary diseases such as congestive heart failure.
Supportive care only
“Do we have anything for treatment? The short answer is, No,” Dr. Williams.
Supportive care is currently the only effective approach for patients with severe HMPV infection.
Ribavirin, used to treat patients with acute RSV infection, has poor in vitro activity against HMPV and poor oral bioavailability and hemolysis, and there are no randomized controlled trials to support its use in this situation.
“It really can’t be recommended, and I don’t recommend it,” he said.

Cardiac arrest in COVID-19 pandemic: ‘Survival is possible’
In the early weeks of the COVID-19 pandemic in the United States, rates of sustained return of spontaneous circulation after out-of-hospital cardiac arrest were lower throughout the country, compared with a year earlier, in one study.
A second study of that period showed that patients with COVID-19 had rates that were better than previously reported of surviving in-hospital cardiac arrest.
Paul S. Chan, MD, presented the out-of-hospital cardiac arrest research, and Oscar J. Mitchell, MD, presented the in-hospital cardiac arrest findings in a late-breaking resuscitation science session at the American Heart Association scientific sessions. The former study was also simultaneously published online Nov. 14 in JAMA Cardiology.
Importantly, “the survival rates were not zero in either setting,” said Dr. Chan, commenting on the implications of both studies taken together.
“The survival rates – either return of circulation or survival to discharge – were not futile,” Dr. Chan, from Saint Luke’s Mid America Heart Institute, Kansas City, Missouri, said in an interview.
“And I think that’s an overall important message – that we can’t write off patients who have a cardiac arrest at this point,” he stressed. “They deserve a response. Although the outcomes might not be as good as we had seen in years prior, we are seeing patients making it out of the hospital and surviving.”
Dr. Mitchell, from the University of Pennsylvania in Philadelphia, echoed this message in an interview.
“I think that the key finding here is that survival is possible after patients with COVID-19 suffer an in-hospital cardiac arrest,” Dr. Mitchell said. “We hope that the information from our study will be of use to frontline providers who are treating patients with COVID-19.”
“In coming weeks, there will likely be increased hospital strain and enormous challenges to providing COVID-19 care,” added Benjamin S. Abella, MD, the senior author of the in-hospital study. Dr. Abella is also from the University of Pennsylvania and was cochair of the Resuscitation Science symposium during the AHA meeting.
“It is crucial that hospital leaders prepare now for how they will manage COVID-19 resuscitation efforts,” Dr. Abella said. “Emergency medicine and critical care leaders must be mindful that many COVID-19 patients with arrest could survive to return to their families.”
“It is important to note both studies demonstrated variations in outcome and that those differences were associated with the differential COVID prevalence and mortality,” session comoderator Cindy H. Hsu, MD, PhD, University of Michigan, said in an interview.
“Future studies,” she said, “should address knowledge gaps including associated comorbidities and affected resuscitation process variables during the COVID-19 pandemic.”
Out-of-hospital cardiac arrest, March 2019 vs. March 2020
Compared with 2019, in 2020, the reported rates of return of spontaneous circulation after out-of-hospital cardiac arrest fell from 25% to 10.6% in New York and from 13.5% to 5.0% in northern Italy – two areas that were severely affected, Dr. Chan noted.
In this study, the researchers aimed to examine whether out-of-hospital cardiac arrest outcomes would be similar throughout the United States, including areas that were less severely affected, in the first weeks of the pandemic.
They linked data from the Cardiac Arrest Registry to Enhance Survival (CARES), which covers an area with about 152 million U.S. residents, with COVID-19 disease mortality data.
There were 9,863 out-of-hospital arrests from March 16 to April 30, 2020, compared with 9,440 cases during this time in 2019.
The patients in both years had a similar age (mean, 62 years) and sex (62% male), but there were more Black patients in 2020 (28% vs. 23%).
Overall, in communities with low to high rates of death from COVID-19, the rate of return of spontaneous circulation was 18% lower in that early pandemic period than in the same time in the previous year (23% vs. 29.8%; adjusted rate ratio, 0.82).
The rates of return of spontaneous circulation were also lower in communities with a low rate of COVID-19 mortality, but to a lesser extent (11%-15% lower in 2020 vs. 2019).
In the subset of emergency medical agencies with complete data on hospital survival, overall rates of survival to discharge were 17% lower during the studied pandemic period versus the same time a year earlier (6.6% vs. 9.8%; adjusted RR, 0.83).
This drop in survival was greater in communities with moderate to high COVID-19 mortality.
These outcomes were not explained by differences in emergency medical services arrival or treatment times, rates of bystander CPR, or initial out-of-hospital cardiac arrest rhythm.
Dr. Chan was a coauthor of an interim guidance issued April 9, 2020, by the AHA and several other medical societies for ways to protect frontline workers from contracting COVID-19 while they were performing CPR.
Communities that were not heavily affected by COVID-19 could have also been following the recommendations, which might have affected outcomes, he speculated.
For example, “when we pause chest compressions it can potentially worsen survival even if it’s for a short period of time. That might explain the lower rates of return of circulation.”
“That guidance was really meant for heavily affected communities,” Dr. Chan added. “Of course, as we speak, the pandemic is pretty much everywhere in the United States. It’s not just in the northeast; it’s not just in Arizona, Florida, California, Texas like it was in the summer. You are seeing surges in 46 of the 50 states.
“If your community is heavily affected by COVID-19 in terms of deaths at this time, paramedics will need to take caution to also help protect themselves, and the guidance may apply at that point,” he said.
In-hospital cardiac arrest, March Through May 2020
The early studies of in-hospital cardiac arrest in patients with COVID-19 showed “concerningly low rates” of return of spontaneous circulation and survival, said Dr. Mitchell.
“The first was a study from Wuhan, which demonstrated a 2.9% 30-day survival and the second was a small cohort from NYC with 0% survival to hospital discharge,” he said. “This raised concerns that offering CPR to patients who had a cardiac arrest from COVID-19 might only hold a low probability of success.”
To investigate this, the researchers formed a COVID study group comprising two hospitals in New York and nine hospitals in the Northeast and West Coast.
They identified 260 hospitalized adult patients with COVID-19 who had in-hospital cardiac arrest between March 1 and May 31, 2020. The patients had a median age of 69 years, and 72% were male. Most had preexisting comorbidities. Most of the cardiac arrests were in the ICU (64%), and almost all were witnessed (91%).
Return of spontaneous circulation occurred in 22% of the patients, and 12% had survived 30 days later. Of the 260 cardiac arrests, most (204) occurred in the New York hospitals.
There was a huge variation in outcomes. The rate of sustained return of spontaneous circulation was much lower in the two hospitals in New York compared with elsewhere (11% vs. 64%), as was 30-day survival (6% vs. 36%).
“Variation in outcomes from [in-hospital cardiac arrest] has been well described prior to the COVID-19 pandemic,” said Dr. Mitchell, “and is felt to be due to a range of factors, including variation in detection and prevention of cardiac arrest, management of patients during the cardiac arrest, and differences in postarrest care – including targeted temperature management and neuroprognostication.”
“We hypothesize that the strains of the COVID-19 pandemic may have amplified these variations (although we were unable to compare hospital performance before and after the pandemic),” he said.
Nevertheless, “in contrast to [earlier] studies, we have found that survival with a good neurological status is possible after in-hospital cardiac arrest in patients with COVID-19, which is certainly reassuring for those of us on the front line.”
Dr. Chan has received research support from the American Heart Association (which helps fund CARES); the National Heart, Lung, and Blood Institute; and Optum Rx. Dr. Abella has received honoraria from NeuroproteXeon, Becton Dickinson, and Physio-Control, and research grants from Medtronic, PCORI, Physio-Control, Stryker, and TerSera. Dr. Mitchell has disclosed no relevant financial relationships.

FROM AHA 2020
In those with obesity, will losing weight cut COVID-19 severity?
As study after study piles up showing that those with obesity who become infected with SARS-CoV-2 are more likely to have severe disease, several experts gave advice for clinicians and patients during the virtual ObesityWeek Interactive 2020 meeting.
Pichamol Jirapinyo, MD, MPH, associate director of bariatric endoscopy at Brigham and Women’s Hospital, Boston, presented a study on those with obesity from New England hospitals which adds to the evidence that this is “a vulnerable population for COVID-19, like elderly or immunocompromised people,” Dr. Jirapinyo said in an interview.
These findings reinforce the need for clinicians to be “more aware of complications of obesity and refer earlier for treatment,” she added.
One audience member wanted to know if there are data showing whether people with a body mass index (BMI) above 35 kg/m2 who successfully lose weight subsequently have lower rates of hospitalization, ICU admission, and death if they become infected with SARS-CoV-2.
Dr. Jirapinyo said she is not aware of any such studies, but anecdotally, two of her patients who had endoscopic sleeve gastroplasty last fall (whose BMI dropped from about 38 to 30) and later became infected with COVID-19 had mild symptoms.
But David A. Kass, MD, director, Institute of CardioScience at Johns Hopkins University, Baltimore, cautioned that
“Whether this gets reversed by weight loss is an attractive hypothesis, but at this point, it’s still a hypothesis,” he stressed.
Changes to immunity, inflammatory signaling in obesity
“There must be north of 600 or more studies by now with this message that obesity – particularly severe obesity with a BMI of 35 and higher – is a strong independent risk factor for worse COVID-19 outcome,” Dr. Kass emphasized.
“[COVID-19] revealed to the public in a somewhat dramatic fashion that being very obese does put one at higher risk of this disease being more debilitating and even fatal,” he added.
“Before this pandemic, many viewed obesity as only a problem if you have the other associated diseases – hypertension, diabetes, heart disease, atherosclerosis, obstructive sleep apnea, etc.”
“What was not as appreciated is that marked obesity changes the body in various ways all by itself – altering metabolism, inflammatory signaling, immune surveillance, and responsiveness (including a less robust response to vaccines that has been written about as well).”
“This is a bit like having a genetic abnormality that makes you at higher risk for getting, say, cancer,” he explained.
“It is there, it is real, it has an impact – but it still does take other stresses to reveal the risk potential. COVID-19 did that with obesity,” he said.
Latest study on effect of obesity, diabetes on COVID-19 severity
The study presented by Dr. Jirapinyo and colleagues identified 1,680 patients with COVID-19 at six hospitals in March 2020. Patients were a mean age of 51 years, had a mean BMI of 29.4, and 39% had obesity. Patients who required hospitalization were more likely to have obesity (46% vs. 35%; P < .0001).
Obesity was a significant risk factor for hospitalization (odds ratio, 1.7), ICU admission (OR, 1.8), and intubation (OR, 1.8; all P < .001), after controlling for age, sex, cardiovascular, pulmonary, liver, and kidney disease, and cancer.
Compared with having a normal weight, having severe obesity was also associated with roughly threefold higher risks of ICU admission and intubation – after controlling for major comorbidities.
Pandemic focuses minds on obesity prevention, treatment
Naveed Sattar, MD, PhD, said in an interview that these latest findings are “highly consistent with other studies that point to excess adiposity as a potential modifiable risk factor for more severe COVID-19.”
It “also strongly suggests that if people are worried about their risk for COVID-19 and want to improve their chances of a milder outcome, then it is reasonable to encourage them to make sustainable lifestyle changes that may lessen weight and improve their fitness levels,” said Dr. Sattar, professor of metabolic medicine, University of Glasgow.
“But of course, the big worry,” he added, “is that many are putting on weight due to lockdowns, less commuting to work, anxiety, and overeating and drinking, etc., so that many are struggling, and especially those at highest risk, such as those living in more overcrowded housing, etc. By contrast, more advantaged folk may have an easier time to improve lifestyles.”
The pandemic highlights that “we need a concerted effort on obesity prevention and treatment,” according to Dr. Sattar.
“For years we have realized links between obesity and chronic cardiometabolic conditions,” he said, “but to think excess weight may also be detrimental to acute effects of a novel virus running amok in the world has focused minds on obesity in a manner not seen before.
“Whether these new painful learnings lead to a more determined effort in countries to improve the obesogenic environment or to place more resources into prevention and management of obesity remains to be seen,” he said.
Increased inquiries about bariatric surgery following COVID-19
Meanwhile, Matthew M. Hutter, MD, MPH, president, American Society for Metabolic and Bariatric Surgery, said in an interview that “COVID-19 and studies like this are now making many aware that obesity is not just a lifestyle choice or a cosmetic issue, but “a disease that needs to be taken seriously” and treated.
“Metabolic and bariatric surgery is a very safe and effective treatment for persons with obesity with a BMI >40 kg/m2 or BMI >35 kg/m2 and related diseases like diabetes, hypertension, sleep apnea, reflux, back pain, and many others,” added Dr. Hutter, who is also professor of surgery, Harvard Medical School, Boston.
“Recently, some metabolic and bariatric centers have seen an increase in patients considering surgery,” he said. “Some say that COVID-19 has made them realize they need to do something to be healthier.”
“Currently, less than 1% of those who could benefit from surgery are actually having” it each year, Dr. Hutter noted, “and I think there are many who should seriously consider surgery to be healthier, live longer, and live better.”

As study after study piles up showing that those with obesity who become infected with SARS-CoV-2 are more likely to have severe disease, several experts gave advice for clinicians and patients during the virtual ObesityWeek Interactive 2020 meeting.
Pichamol Jirapinyo, MD, MPH, associate director of bariatric endoscopy at Brigham and Women’s Hospital, Boston, presented a study on those with obesity from New England hospitals which adds to the evidence that this is “a vulnerable population for COVID-19, like elderly or immunocompromised people,” Dr. Jirapinyo said in an interview.
These findings reinforce the need for clinicians to be “more aware of complications of obesity and refer earlier for treatment,” she added.
One audience member wanted to know if there are data showing whether people with a body mass index (BMI) above 35 kg/m2 who successfully lose weight subsequently have lower rates of hospitalization, ICU admission, and death if they become infected with SARS-CoV-2.
Dr. Jirapinyo said she is not aware of any such studies, but anecdotally, two of her patients who had endoscopic sleeve gastroplasty last fall (whose BMI dropped from about 38 to 30) and later became infected with COVID-19 had mild symptoms.
But David A. Kass, MD, director, Institute of CardioScience at Johns Hopkins University, Baltimore, cautioned that
“Whether this gets reversed by weight loss is an attractive hypothesis, but at this point, it’s still a hypothesis,” he stressed.

'Tragic' milestone: 1 million children with COVID-19
The number of new cases soared in the past week as the United States exceeded 1 million children infected with the coronavirus, according to a report from the American Academy of Pediatrics and the Children’s Hospital Association.
For the first time, the number of cases in children for the week ending Nov. 12 passed 100,000, and it didn’t stop until it reached 111,946, bringing the total for the pandemic to 1,039,464 reported cases in 49 states (New York is not reporting ages), the District of Columbia, New York City, and Guam, the AAP and the CHA said in their weekly COVID-19 update.
“As a pediatrician who has practiced medicine for over 3 decades, I find this number staggering and tragic. We haven’t seen a virus flash through our communities in this way since before we had vaccines for measles and polio,” AAP President Sally Goza, MD, said in a written statement.
The previous 1-week high of almost 74,000 cases came just last week, and that number had surpassed the previous week’s new high of 61,000. The number of cumulative child cases, meanwhile, has doubled since Sept. 3, when it was just over 513,000. Children now represent 11.5% of all COVID-19 cases since the start of the pandemic in the jurisdictions reporting age distribution, the AAP and CHA said.
For the week ending Nov. 12, COVID-19 cases children made up 14% of cases nationally, rising from 13% the week before and reversing a decline that started in mid-October, the AAP/CHA data show.
The two groups continue to note the rarity of severe illness in children, but the number of deaths nationally had its biggest 1-week increase since late July, as the total rose from 123 to 133 in the 42 states reporting such data by age, as well as New York City. The cumulative hospitalization rate for children decreased slightly in the past week and is now down to 1.6% in the 23 states (and NYC) with available data, the AAP and CHA said.
The AAP called on elected leaders to enact a national strategy to combat the spread of the virus and urged health authorities to do more to collect data on longer-term impacts on children.
We’re very concerned about how this will impact all children, including toddlers who are missing key educational opportunities, as well as adolescents who may be at higher risk for anxiety and depression,” Dr. Goza said.

New-onset AFib common but unrecognized in the month after cardiac surgery
One in five patients at elevated stroke risk who underwent cardiac surgery with no history of atrial fibrillation preoperatively or at discharge developed postoperative AFib documented on a continuous cardiac rhythm monitoring device within the first 30 days after leaving the hospital in the randomized SEARCH-AF trial.
“Postoperative atrial fibrillation after cardiac surgery is not confined to the hospitalization period per se. We believe that these data should help inform on clinical practice guidelines on monitoring for postoperative atrial fibrillation in such patients,” said Subodh Verma, MD, PhD, reporting the results at the virtual American Heart Association scientific sessions.
“Guidelines provide little or no direction on optimal monitoring post cardiac surgery, particularly if patients are in sinus rhythm at discharge,” the surgeon noted.
SEARCH-AF was an open-label, multicenter study that included 336 patients at elevated stroke risk with an average CHA2DS2-VASc score of 4, no history of preoperative AFib, and none more than briefly with resolution during hospitalization. They were randomized to 30 days of postdischarge continuous cardiac rhythm monitoring with Medtronic’s SEEQ device, to Icentia’s CardioSTAT device, or to usual care, with Holter monitoring at the discretion of the treating physicians.
The primary result was a cumulative duration of AFib or atrial flutter of 6 minutes or longer during that 30-day period. This outcome occurred in 19.6% of the enhanced cardiac monitoring group and 1.7% of usual-care controls. Thus, there is an ongoing persistent occult risk of AFib that typically goes unrecognized. This 10-fold difference in the incidence of postoperative AFib translated into an absolute 17.9% between-group difference and a number-needed-to-treat of 6.
The secondary outcome of a cumulative atrial fib/flutter burden of 6 hours or more during 30 days occurred in 8.6% of the continuously monitored group and none of the controls. A cumulative AFib/flutter burden of 24 hours or greater occurred in 3.1% of the enhanced cardiac monitoring group and zero controls. These are AFib burdens that in other studies have been linked to increased risks of stroke and death, said Dr. Verma, professor of cardiovascular surgery at the University of Toronto.
“From a clinical standpoint, what this trial tells me is for my patients being discharged home tomorrow from the hospital, where they haven’t had AFib and I haven’t initiated anticoagulation, I have a low threshold to monitor these patients and to watch for periods of sustained unrecognized atrial fibrillation,” the surgeon added.
Experts: Results won’t change guidelines
Discussant Ben Freedman, MBBS, PhD, noted that the U.S. Preventive Services Task Force has stated that there are insufficient data available to recommend ECG screening for AFib to prevent stroke. Before the task force can be convinced to recommend it and for payers to cover it, a number of key questions need to be answered. And the SEARCH-AF trial doesn’t provide those answers, said Dr. Freedman, professor of cardiology and deputy director of the Heart Research Institute at the University of Sydney.
First off, it’ll be necessary to know if the risk posed by screen-detected AFib, including postoperative AFib, is similar to that of clinical AFib. Next, it must be shown that this screen-detected postoperative AFib is actionable; that is, that a screening strategy to detect postoperative AFib arising after discharge and then treat with oral anticoagulants will actually prevent more strokes than with usual care. There are large studies underway addressing that question, including HEARTLINE, STROKESTOP, and SAFERGUARD-AF, he observed.
In an interview, Rod S. Passman, MD, who gave a state-of-the-art talk on AFib detection at the meeting and wasn’t involved in SEARCH-AF, said he doesn’t consider the results practice-changing.
“It’s not guideline-changing because you’ve only shown that more intensive monitoring finds more AFib. Guideline-changing would be that finding that AFib and doing something about it impacts hard outcomes, and we don’t have that data yet,” said Dr. Passman, an electrophysiologist who is director of the Center for Arrhythmia Research and professor of medicine and preventive medicine at Northwestern University, Chicago.
The SEARCH-AF trial was funded by the Heart and Stroke Foundation of Canada, Bristol Myers Squibb, Pfizer, and Boehringer Ingelheim. Dr. Verma reported having received speaker’s fees and/or research support from those and other pharmaceutical companies. Dr. Freedman disclosed having no financial conflicts.

“From a clinical standpoint, what this trial tells me is for my patients being discharged home tomorrow from the hospital, where they haven’t had AFib and I haven’t initiated anticoagulation, I have a low threshold to monitor these patients and to watch for periods of sustained unrecognized atrial fibrillation,” the surgeon added.
Experts: Results won’t change guidelines
Discussant Ben Freedman, MBBS, PhD, noted that the U.S. Preventive Services Task Force has stated that there are insufficient data available to recommend ECG screening for AFib to prevent stroke. Before the task force can be convinced to recommend it and for payers to cover it, a number of key questions need to be answered. And the SEARCH-AF trial doesn’t provide those answers, said Dr. Freedman, professor of cardiology and deputy director of the Heart Research Institute at the University of Sydney.
First off, it’ll be necessary to know if the risk posed by screen-detected AFib, including postoperative AFib, is similar to that of clinical AFib. Next, it must be shown that this screen-detected postoperative AFib is actionable; that is, that a screening strategy to detect postoperative AFib arising after discharge and then treat with oral anticoagulants will actually prevent more strokes than with usual care. There are large studies underway addressing that question, including HEARTLINE, STROKESTOP, and SAFERGUARD-AF, he observed.
In an interview, Rod S. Passman, MD, who gave a state-of-the-art talk on AFib detection at the meeting and wasn’t involved in SEARCH-AF, said he doesn’t consider the results practice-changing.
“It’s not guideline-changing because you’ve only shown that more intensive monitoring finds more AFib. Guideline-changing would be that finding that AFib and doing something about it impacts hard outcomes, and we don’t have that data yet,” said Dr. Passman, an electrophysiologist who is director of the Center for Arrhythmia Research and professor of medicine and preventive medicine at Northwestern University, Chicago.
The SEARCH-AF trial was funded by the Heart and Stroke Foundation of Canada, Bristol Myers Squibb, Pfizer, and Boehringer Ingelheim. Dr. Verma reported having received speaker’s fees and/or research support from those and other pharmaceutical companies. Dr. Freedman disclosed having no financial conflicts.

What hospitalists need to know about health care reimbursement and denial prevention
Under a fee-for-service payment model, health care providers get paid by private and public payers for patient services such as physician visits, hospital stays, procedures, and tests. In an ideal world, providers would receive accurate, complete, and timely reimbursements. Unfortunately, the reality is far from ideal, where payment denials and delays are a common occurrence.
According to one study, out of $3 trillion in total claims submitted by health care organizations, an estimated 9% of charges ($262 billion), were initially denied.1 The good news is that 90% of all denials are preventable, and two-thirds of those preventable denials can be successfully appealed.2
Hospitalists are essential in preventing denials for hospital services and should be familiar with the basics of health care reimbursement and common reasons for denials. In this article we will provide an overview of the U.S. health care payment system, revenue cycle management and types of denials, and focus on the role of physician advisors and hospitalists in preventing and combating denials.
Overview of the U.S. health care payment system
In 2018 alone, the U.S. spent $3.6 trillion on health care. Of those dollars, 33% went to payments for hospital care and 20% went to physician and clinical services.3 So where do the nation’s health care dollars come from?
The United States has a complex multiple-payer system that includes private insurance companies and public payers funded by the federal and state governments, such as Medicare and Medicaid. Per the National Association of Insurance Commissioners’ 2018 Market Share Reports, there are 125 private accident and health insurance companies in the U.S., with the top five – UnitedHealth, Kaiser, Anthem, Humana, and CVS – holding a cumulative market share of almost 40%.4
Medicare accounts for 15% of federal budget spending and provides insurance coverage to almost 60 million people who are 65 and older, have end-stage renal disease, or have been approved for Social Security disability insurance benefits.5 Medicare Part A covers hospital, skilled nursing facility, home health, and hospice care. For example, for inpatient stays, Medicare Part A pays hospitals a predetermined rate per discharge according to the Medicare Severity Diagnosis Related Groups (MS-DRGs), which are based on the principal and secondary diagnoses, and performed procedures.6
Medicare Part B covers physician services and outpatient services and supplies, including labs and durable medical equipment, which are paid based on submitted Healthcare Common Procedure Coding System (HCPCS) codes.7 It is important to know that hospital observation stays are considered outpatient services, and are paid by Medicare Part B. Outpatient stays often are reimbursed at a lower rate than inpatient admissions, even in cases with similar utilization of hospital resources.
Medicaid is jointly funded by the states and the federal government and offers insurance coverage to more than 75 million eligible low-income adults, children, pregnant women, elderly adults, and people with disabilities. Over 10 million people are dually eligible for both Medicare and Medicaid.5 Increasingly, government payers, both state and federal, are contracting with private insurance companies to deliver Medicare and Medicaid services, also known as Medicare Advantage and Managed Medicaid Plans.
According to the U.S. Department of Treasury, in the 2019 fiscal year (October 2018 to September 2019), 33% of the nation’s health care dollars came from private insurance, 21% from Medicare, 16% from Medicaid, 15% from other government programs (for example, Veteran Affairs), 10% from out-of-pocket, and 4% from other private sources.5
Understanding revenue cycle management and denials
Providers, such as physicians or hospitals, submit claims to insurance companies that include, among other information, patient demographics and insurance, diagnoses, MS-DRGs and/or HCPCS codes, and charges. Revenue cycle management’s goal is to receive accurate, complete, and timely reimbursement for provided patient services, which is a complex and resource-intensive process.
According to the Healthcare Financial Management Association (HFMA), revenue cycle management includes “all administrative and clinical functions that contribute to the capture, management, and collection of patient service revenue.” These functions could be broken down into four main categories:
- Claims preparation (for example, patient registration, insurance eligibility, benefit verifications, and preauthorization).
- Claims submission (for example, charge capture, medical coding based on medical record documentation and claims transmission).
- Claims management (for example, payment posting, denial management, and patient collections).
- Reporting and analysis.
Claim denial is “the refusal of an insurance company or carrier to honor a request by an individual (or his or her provider) to pay for health care services obtained from a health care professional.”8 Payers can deny an entire claim or provide only a partial payment. Initial denial rate is tracked at the claim level (number of claims denied/number of claims submitted) and at the dollar level (total dollar amount of claims denied/total dollar amount of claims submitted).
Denials are classified as hard versus soft, and clinical versus technical or administrative:
- Hard denials result in lost revenue unless successfully appealed (for example, lack of medical necessity).
- Soft denials do not require appeal and may be paid if a provider corrects the claim or submits additional information (for example, missing or inaccurate patient information, and missing medical records).
- Clinical denials are based on medical necessity, including level of care determination (for example, inpatient versus outpatient) and length of stay. They can be concurrent and retrospective and typically start as soft denials.
- Technical or administrative denials are based on reasons other than clinical (for example, failure to preauthorize care or lack of benefits).
According to the Advisory Board’s 2017 survey of hospitals and health care systems, 50% of initial denials were technical/demographic errors, 20% medical necessity, 16% eligibility, and 14% authorization. Forty seven percent of those denials came from commercial payers, 33% from Medicare/Medicare Advantage, 17% from Medicaid, and 3% from other payers.9
Determination of medical necessity may vary by payer. As an example, let’s look at inpatient admissions. According to the Medicare Two-Midnight Rule, inpatient admission is appropriate “if the admitting practitioner expects the beneficiary to require medically necessary hospital care spanning two or more midnights, and such reasonable expectation is supported by the medical record documentation.”10
Medicare guidelines acknowledge that a physician’s decision to admit a patient is based on complex medical factors including, but not limited to:
- The beneficiary history and comorbidities, and the severity of signs and symptoms (also known as Severity of Illness or SI).
- Current medical needs (also known as Intensity of Service or IS).
- The risk of an adverse event.
Generally, private payers do not follow the Two-Midnight Rule, and instead utilize evidence-based MCG guidelines,11 InterQual® criteria12 or internal criteria to determine if an inpatient admission is “medically necessary.” Hospital utilization review nurses often use MCG and/or InterQual® to aid admission status decisions and may request secondary review by a physician if medical necessity for an inpatient admission is not clear-cut.
The role of physician advisors
Considering the rising financial pressure and growing complexity of private and public payers’ rules and regulations, many hospitals turned to physician advisors to help prevent and reduce denials. Typically, physician advisors perform concurrent secondary reviews to help determine the most appropriate level of care, participate in peer-to-peer discussions with payers, and write formal appeals to overturn clinical denials.
“Physician advisors are generally not in the business of critiquing clinical practice, instead they review whether the chart documentation supports initial and continued hospitalization,” said Charles Locke, MD, senior physician advisor at the Johns Hopkins Hospital and president of the American College of Physician Advisors (ACPA). “However, physician advisors should seek additional information and provide feedback in those cases where the documentation does not support medical necessity for hospitalization.”
Many physician advisors are current or former hospitalists. Chris Shearer, MD, chief medical officer for remote advisory at Sound Physicians Advisory Services, says that “hospitalists are the natural physician advisors as they have a working knowledge of what patients need to be inpatients and which are less sick and likely to be discharged quickly.”
The role of physician advisors extends beyond reviews to include physician engagement and education. Physician advisors are a critical link between physicians, utilization review nurses, case managers, and clinical documentation integrity (CDI) and revenue cycle teams, and are increasingly involved in hospital-wide denial prevention efforts.
Physician advisors are invaluable in identifying and validating root causes for clinical denials and generating potential solutions, as they bring to the table:
- Clinical expertise.
- Understanding of clinical workflows.
- Knowledge of the most current public and private payers’ regulations.
- Insight into hospital-specific clinical documentation opportunities (for example, by diagnosis, procedure, service line, and provider).
- Understanding of payers’ reasons for clinical denials through peer-to-peer discussions
The role of hospitalists in preventing clinical denials
I asked three experienced physician advisors – Dr. Locke, Dr. Shearer, and Deepak Pahuja, MD, chief medical officer at Aerolib Healthcare Solutions – what hospitalists can do to prevent clinical denials. The experts had the following five recommendations:
1. “THINK IN INK.”
The best tool in combating denials is well-documented clinical judgment that outlines:
- WHY the patient requires hospitalization, based on severity of presenting signs and symptoms, comorbidities, and risk of complications.
- WHAT the plan of care is, including diagnostic tests and/or interventions.
- HOW LONG you anticipate the patient will be in the hospital, including potential implications of social determinants (for example homelessness, active drug use) on discharge planning.
2. MASTER THE TWO-MIDNIGHT RULE.
If you expect that a Medicare Part A patient will require two or more midnights in the hospital, document it in the history and physical along with supporting clinical reasoning and sign an inpatient order. If the patient is discharged prior to the second midnight, document the reason in the progress notes and the discharge summary (for example, death, transfer to another hospital, departure against medical advice, faster than expected clinical improvement, or election of hospice in lieu of continued treatment in the hospital). Remember that Medicare Advantage plans may not follow the Two-Midnight rule and instead may use MCG guidelines, InterQual®, or internal criteria.
3. KNOW “SLAM DUNK” MCG CRITERIA FOR TOP DIAGNOSES.
Most large private payers utilize MCG guidelines to determine medical necessity for hospital admissions. Those guidelines are complex and change every year, and it is not required for hospitalists to know them all. However, it might help to remember a few key inpatient admission criteria for the top 5 to 10 diagnoses, such as:
- First episode of heart failure without prior history.
- Upper gastrointestinal bleeding with liver cirrhosis, syncope, or orthostatic hypotension.
- Pneumonia with documented hypoxia, outpatient treatment failure, pneumonia severity index (PSI) class 4 or 5, or CURB-65 score of 3 or greater.
- Cellulitis with outpatient treatment failure or high-risk comorbid conditions (cirrhosis, symptomatic heart failure, immunosuppression, or HbA1c greater than 10%).
4. EACH DAY, DEFEND WHY THE PATIENT NEEDS TO BE IN THE HOSPITAL.
Don’t let your progress notes be swallowed by a “copy-forward” monster and instead provide daily updates, such as:
- Up-to-date clinical status and response to interventions (for example, oxygenation or pain level).
- Updated plan of care: current interventions, additional diagnostic workup, or changes to the intensity of care (for example, increased intravenous pain medication dose or frequency).
- Why the patient cannot be safely discharged to a lower level of care (for example, a skilled nursing facility or home).
5. WORK WITH YOUR UTILIZATION REVIEW NURSES AND PHYSICIAN ADVISORS.
In the end, the two most powerful tools in combating clinical denials for hospital services are good medicine and clear documentation. Armed with an understanding of health care reimbursement and denial prevention, hospitalists can help their hospitals prevent unnecessary clinical denials and receive the reimbursements they deserve.”

According to the U.S. Department of Treasury, in the 2019 fiscal year (October 2018 to September 2019), 33% of the nation’s health care dollars came from private insurance, 21% from Medicare, 16% from Medicaid, 15% from other government programs (for example, Veteran Affairs), 10% from out-of-pocket, and 4% from other private sources.5
Understanding revenue cycle management and denials
Providers, such as physicians or hospitals, submit claims to insurance companies that include, among other information, patient demographics and insurance, diagnoses, MS-DRGs and/or HCPCS codes, and charges. Revenue cycle management’s goal is to receive accurate, complete, and timely reimbursement for provided patient services, which is a complex and resource-intensive process.
According to the Healthcare Financial Management Association (HFMA), revenue cycle management includes “all administrative and clinical functions that contribute to the capture, management, and collection of patient service revenue.” These functions could be broken down into four main categories:
- Claims preparation (for example, patient registration, insurance eligibility, benefit verifications, and preauthorization).
- Claims submission (for example, charge capture, medical coding based on medical record documentation and claims transmission).
- Claims management (for example, payment posting, denial management, and patient collections).
- Reporting and analysis.
Claim denial is “the refusal of an insurance company or carrier to honor a request by an individual (or his or her provider) to pay for health care services obtained from a health care professional.”8 Payers can deny an entire claim or provide only a partial payment. Initial denial rate is tracked at the claim level (number of claims denied/number of claims submitted) and at the dollar level (total dollar amount of claims denied/total dollar amount of claims submitted).
Denials are classified as hard versus soft, and clinical versus technical or administrative:
- Hard denials result in lost revenue unless successfully appealed (for example, lack of medical necessity).
- Soft denials do not require appeal and may be paid if a provider corrects the claim or submits additional information (for example, missing or inaccurate patient information, and missing medical records).
- Clinical denials are based on medical necessity, including level of care determination (for example, inpatient versus outpatient) and length of stay. They can be concurrent and retrospective and typically start as soft denials.
- Technical or administrative denials are based on reasons other than clinical (for example, failure to preauthorize care or lack of benefits).
According to the Advisory Board’s 2017 survey of hospitals and health care systems, 50% of initial denials were technical/demographic errors, 20% medical necessity, 16% eligibility, and 14% authorization. Forty seven percent of those denials came from commercial payers, 33% from Medicare/Medicare Advantage, 17% from Medicaid, and 3% from other payers.9
Determination of medical necessity may vary by payer. As an example, let’s look at inpatient admissions. According to the Medicare Two-Midnight Rule, inpatient admission is appropriate “if the admitting practitioner expects the beneficiary to require medically necessary hospital care spanning two or more midnights, and such reasonable expectation is supported by the medical record documentation.”10
Medicare guidelines acknowledge that a physician’s decision to admit a patient is based on complex medical factors including, but not limited to:
- The beneficiary history and comorbidities, and the severity of signs and symptoms (also known as Severity of Illness or SI).
- Current medical needs (also known as Intensity of Service or IS).
- The risk of an adverse event.
Generally, private payers do not follow the Two-Midnight Rule, and instead utilize evidence-based MCG guidelines,11 InterQual® criteria12 or internal criteria to determine if an inpatient admission is “medically necessary.” Hospital utilization review nurses often use MCG and/or InterQual® to aid admission status decisions and may request secondary review by a physician if medical necessity for an inpatient admission is not clear-cut.
The role of physician advisors
Considering the rising financial pressure and growing complexity of private and public payers’ rules and regulations, many hospitals turned to physician advisors to help prevent and reduce denials. Typically, physician advisors perform concurrent secondary reviews to help determine the most appropriate level of care, participate in peer-to-peer discussions with payers, and write formal appeals to overturn clinical denials.
“Physician advisors are generally not in the business of critiquing clinical practice, instead they review whether the chart documentation supports initial and continued hospitalization,” said Charles Locke, MD, senior physician advisor at the Johns Hopkins Hospital and president of the American College of Physician Advisors (ACPA). “However, physician advisors should seek additional information and provide feedback in those cases where the documentation does not support medical necessity for hospitalization.”
Many physician advisors are current or former hospitalists. Chris Shearer, MD, chief medical officer for remote advisory at Sound Physicians Advisory Services, says that “hospitalists are the natural physician advisors as they have a working knowledge of what patients need to be inpatients and which are less sick and likely to be discharged quickly.”
The role of physician advisors extends beyond reviews to include physician engagement and education. Physician advisors are a critical link between physicians, utilization review nurses, case managers, and clinical documentation integrity (CDI) and revenue cycle teams, and are increasingly involved in hospital-wide denial prevention efforts.
Physician advisors are invaluable in identifying and validating root causes for clinical denials and generating potential solutions, as they bring to the table:
- Clinical expertise.
- Understanding of clinical workflows.
- Knowledge of the most current public and private payers’ regulations.
- Insight into hospital-specific clinical documentation opportunities (for example, by diagnosis, procedure, service line, and provider).
- Understanding of payers’ reasons for clinical denials through peer-to-peer discussions
The role of hospitalists in preventing clinical denials
I asked three experienced physician advisors – Dr. Locke, Dr. Shearer, and Deepak Pahuja, MD, chief medical officer at Aerolib Healthcare Solutions – what hospitalists can do to prevent clinical denials. The experts had the following five recommendations:
1. “THINK IN INK.”
The best tool in combating denials is well-documented clinical judgment that outlines:
- WHY the patient requires hospitalization, based on severity of presenting signs and symptoms, comorbidities, and risk of complications.
- WHAT the plan of care is, including diagnostic tests and/or interventions.
- HOW LONG you anticipate the patient will be in the hospital, including potential implications of social determinants (for example homelessness, active drug use) on discharge planning.
2. MASTER THE TWO-MIDNIGHT RULE.
If you expect that a Medicare Part A patient will require two or more midnights in the hospital, document it in the history and physical along with supporting clinical reasoning and sign an inpatient order. If the patient is discharged prior to the second midnight, document the reason in the progress notes and the discharge summary (for example, death, transfer to another hospital, departure against medical advice, faster than expected clinical improvement, or election of hospice in lieu of continued treatment in the hospital). Remember that Medicare Advantage plans may not follow the Two-Midnight rule and instead may use MCG guidelines, InterQual®, or internal criteria.
3. KNOW “SLAM DUNK” MCG CRITERIA FOR TOP DIAGNOSES.
Most large private payers utilize MCG guidelines to determine medical necessity for hospital admissions. Those guidelines are complex and change every year, and it is not required for hospitalists to know them all. However, it might help to remember a few key inpatient admission criteria for the top 5 to 10 diagnoses, such as:
- First episode of heart failure without prior history.
- Upper gastrointestinal bleeding with liver cirrhosis, syncope, or orthostatic hypotension.
- Pneumonia with documented hypoxia, outpatient treatment failure, pneumonia severity index (PSI) class 4 or 5, or CURB-65 score of 3 or greater.
- Cellulitis with outpatient treatment failure or high-risk comorbid conditions (cirrhosis, symptomatic heart failure, immunosuppression, or HbA1c greater than 10%).
4. EACH DAY, DEFEND WHY THE PATIENT NEEDS TO BE IN THE HOSPITAL.
Don’t let your progress notes be swallowed by a “copy-forward” monster and instead provide daily updates, such as:
- Up-to-date clinical status and response to interventions (for example, oxygenation or pain level).
- Updated plan of care: current interventions, additional diagnostic workup, or changes to the intensity of care (for example, increased intravenous pain medication dose or frequency).
- Why the patient cannot be safely discharged to a lower level of care (for example, a skilled nursing facility or home).
5. WORK WITH YOUR UTILIZATION REVIEW NURSES AND PHYSICIAN ADVISORS.
In the end, the two most powerful tools in combating clinical denials for hospital services are good medicine and clear documentation. Armed with an understanding of health care reimbursement and denial prevention, hospitalists can help their hospitals prevent unnecessary clinical denials and receive the reimbursements they deserve.”

Moderna: Interim data show 94.5% efficacy for COVID-19 vaccine, will seek FDA EUA
The Moderna mRNA-1273 vaccine, in development to prevent COVID-19, yielded 94.5% efficacy in early results and is generally well tolerated, the company announced early Monday. The product can be stored at refrigeration temperatures common to many physician offices, pharmacies, and hospitals.
The first interim results of the phase 3 COVE trial included 95 participants with confirmed COVID-19. An independent data safety monitoring board, which was appointed by the National Institutes of Health, informed Moderna that 90 of the patients who were positive for COVID-19 were in a placebo group and that 5 patients were in the mRNA-1273 vaccine group, resulting in a vaccine efficacy of 94.5% (P < .0001).
Interim data included 11 patients with severe COVID-19, all of whom were in the placebo group.
“This positive interim analysis from our phase 3 study has given us the first clinical validation that our vaccine can prevent COVID-19 disease, including severe disease,” said Stéphane Bancel, CEO of Moderna, said in a statement.
The vaccine met its primary study endpoint, which was based on adjudicated data that were collected starting 2 weeks after the second dose of mRNA-1273. The interim study population included people who could be at higher risk for COVID-19, including 15 adults aged 65 years and older and 20 participants from diverse communities.
Safety data
The DSMB also reviewed safety data for the COVE study interim results. The vaccine was generally safe and well tolerated, as determined on the basis of solicited adverse events. Most adverse events were mild to moderate and were generally short-lived, according to a company news release.
Injection-site pain was reported in 2.7% of participants after the first dose. After the second dose, 9.7% of participants reported fatigue, 8.9% reported myalgia, 5.2% reported arthralgia, 4.5% reported headache, 4.1% reported pain, and 2.0% reported erythema or redness at the injection site.
Moderna plans to request emergency-use authorization (EUA) from the Food and Drug Administration in the coming weeks. The company expects that the EUA will be based on more data from the COVE study, including a final analysis of 151 patients with a median follow-up of more than 2 months. Moderna also plans to seek authorizations from global regulatory agencies.
The company expects to have approximately 20 million doses of mRNA-1273 ready to ship in the United States by the end of the year. In addition, the company says it remains on track to manufacture between 500 million and 1 billion doses globally in 2021.
Moderna is developing distribution plans in conjunction with the Centers for Disease Control and Prevention, the federal government’s Operation Warp Speed, and McKesson, a COVID-19 vaccine distributor contracted by the U.S. government.
Refrigeration requirements
The mRNA-1273 vaccine can be shipped and stored for up to 6 months at –20° C (about –4° F), a temperature maintained in most home or medical freezers, according to Moderna. The company expects that, after the product thaws, it will remain stable at standard refrigerator temperatures of 2°-8° C (36°-46° F) for up to 30 days within the 6-month shelf life.
Because the mRNA-1273 vaccine is stable at these refrigerator temperatures, it can be stored at most physicians’ offices, pharmacies, and hospitals, the company noted. In contrast, the similar Pfizer BTN162b2 vaccine – early results for which showed a 90% efficacy rate – requires shipment and storage at “deep-freeze” conditions of –70° C or –80° C, which is more challenging from a logistic point of view.
Moderna’s mRNA-1273 can be kept at room temperature for up to 12 hours after removal from a refrigerator for patient administration. The vaccine will not require dilution prior to use.
More than 30,000 people aged older than 18 years in the United States are enrolled in the COVE study. The research is being conducted in collaboration with the National Institute of Allergy and Infectious Diseases and the Biomedical Advanced Research and Development Authority, part of the Office of the Assistant Secretary for Preparedness and Response at the Department of Health & Human Services.

Intravenous iron reduces HF readmissions: AFFIRM-AHF
Iron supplementation reduces heart failure (HF) readmissions in iron-deficient patients hospitalized for acute HF, according to results of the AFFIRM-AHF trial.
After 52 weeks, intravenous ferric carboxymaltose (Ferinject) reduced the risk of total HF hospitalizations and cardiovascular (CV) death by 21% compared with placebo (293 vs 372 events; rate ratio [RR] 0.79; 95% CI, 0.62 - 1.01).
Although the composite primary endpoint failed to achieve statistical significance, it was driven by a significant 26% reduction in the risk of total HF hospital readmissions (P = .013) without an effect on CV mortality (P =.809).
Because the management and follow-up of patients was affected by the COVID-19 pandemic, a prespecified sensitivity analysis was performed that censored patients in each country at the date when its first COVID-19 patient was reported, explained principal investigator Piotr Ponikowski, MD, PhD, Wroclaw Medical University, Wroclaw, Poland.
That analysis revealed a significant 30% reduction in total HF readmissions (P = .005) in patients receiving ferric carboxymaltose (FCM), as well as significant benefits on the primary composite and secondary endpoints.
Notably, 80% of patients required only one or two injections and HF hospitalizations were reduced irrespective of anemia status.
“Iron deficiency should be searched in patients hospitalized with acute heart failure — assessed using a simple blood test — and is now an important therapeutic target,” Ponikowski said at the virtual American Heart Association (AHA) Scientific Sessions 2020.
The results were also published simultaneously in The Lancet.
Iron deficiency is present in up to 70% of patients with acute HF and a predictor of poor outcome, independent of anemia and ejection fraction, he noted.
The FAIR-HF, CONFIRM-HF, and EFFECT-HF trials demonstrated that IV iron supplementation improves exercise capacity, symptoms, and quality of life in iron-deficient HF patients.
However, no such benefit was seen with oral IV in the IRONOUT trial. “So it seems if we are to replace iron, it needs to be done using intravenous therapy,” said John McMurray, MD, University of Glasgow, Scotland, who was invited to discuss the results.
He observed that the reduction in HF hospitalizations in AFFIRM-AHF were relatively modest and that the trial was never expected to show a benefit on CV mortality. Also, the COVID-19 sensitivity analysis providing more convincing effects is a valid approach and one recommended by regulators.
Further, the findings are supported by independent evidence in chronic kidney disease, from the PIVOTAL trial, that intravenous iron reduces HF hospitalizations, McMurray said.
“The million-dollar question, of course, is what will the results of this study mean for the guidelines: I think they probably will change the guidelines,” he said. “Certainly, I hope they will change the US guidelines, which have really given a very lukewarm recommendation for intravenous iron and I think that should probably be stronger.”
In a class IIb recommendation, the 2017 American College of Cardiology/AHA/Heart Failure Society of America heart failure guidelines say intravenous iron “might be reasonable” to improve functional status and quality of life in New York Heart Association class II and III patients with iron deficiency.
The 2016 European Society of Cardiology guidelines include a class IIa recommendation that IV iron “should be considered” in iron-deficient patients with symptomatic HF with reduced ejection fraction.
“This is the first large-scale [trial] of IV supplementation that could potentially change the way we approach patients, particularly those with hospitalized heart failure,” past AHA president Clyde Yancy, MD, MSc, Northwestern University Feinberg School of Medicine in Chicago, said during an earlier press briefing.
He pointed out that clinicians have been circumspect about the early IV iron data. “I have to congratulate you because you’ve changed the narrative,” Yancy said. “We have to start thinking about iron deficiency; we have to think about how we incorporate this in treatment protocols.”
Press briefing panelist Marc Pfeffer, MD, PhD, Brigham and Women’s Hospital and Harvard Medical School in Boston, acknowledged he was among those circumspect.
“I’m no longer a skeptic and I want to congratulate them for showing it’s a risk factor,” he said. “It’s one thing to have a risk factor; it’s another to be a modifiable risk factor and I think that’s what’s so exciting about this.”
The double-blind, phase 4 AFFIRM-AHF trial randomly assigned 1132 patients to receive a bolus injection of ferric carboxymaltose or normal saline before hospital discharge for an acute HF episode. Subsequent treatment was given, as needed, up to 24 weeks post-randomization.
At admission, all patients had left ventricular ejection fractions less than 50% and iron deficiency (serum ferritin <100 ng/mL or serum ferritin 100-299 ng/mL if transferrin saturation <20%).
The modified intention-to-treat (mITT) analysis included 558 FCM patients and 550 controls in whom study treatment was started and for whom at least one post-randomization value was available.
Press briefing discussant Nancy Sweitzer, MD, PhD, director of the University of Arizona’s Sarver Heart Center in Tucson, said AFFIRM-AHF is an “important trial likely to change guidelines” and “targeted one of the highest risk populations we have in heart failure.”
Patients with iron deficiency tend to be elderly with more comorbidities, have longer hospital lengths of stay, and higher readmission rates. “So impacting hospitalizations in this population is incredibly impactful,” she said.
“Awareness and assessment of iron deficiency are an important part of inpatient care of patients with ejection fractions less than or equal to 50% and acute decompensated heart failure, and I think all of us in the community need to pay much more attention to this issue.”
As with any new therapy, there are implementation challenges such as how to monitor patients and deliver the therapy in a cost-effective way, Sweitzer said.
The trial focused on the most vulnerable period for HF patients, but these patients should be rechecked every 3 to 4 months for iron deficiency, Ponikowski observed during the briefing.
“This is a modifiable risk factor,” he said. “We only need to remember, we only need to assess it, and we have a very, very simple tool in our hands. We just need to measure two biomarkers, transferrin saturation and ferritin — that’s all.”
Unanswered questions include the mechanism behind the reduction in hospitalization, the relationship of benefit to hemoglobin levels, and whether there is a differential benefit based on age, presence of ischemia, or sex, especially as women tend to be more severely affected by iron deficiency, Sweitzer said.
During the formal presentation, Ponikowski said the primary endpoint was consistent in subgroup analyses across baseline hemoglobin, estimated glomerular filtration rate, and N-terminal pro-brain natriuretic peptide levels, HF etiology, ejection fraction, and whether HF was diagnosed prior to the index hospitalization.
Treatment with FCM was safe, with no significant differences between the FCM and placebo groups in serious adverse events (45% vs 51%) or adverse events leading to study discontinuation (18% vs 17%), he reported. The most common adverse events were cardiac disorders (40.1% vs 44.3%) and infections (18.2% vs 22%).
AFFIRM-AHF is the first of three ongoing mortality and morbidity trials in heart failure with intravenous ferric carboxymaltose; the others are FAIR-HF2 and HEART-FID. Additional insights are also expected next year on intravenous iron isomaltoside from the Scottish-based IRONMAN trial in 1300 HF patients with iron deficiency.
The study was sponsored by Vifor International. Ponikowski has received research grants and personal fees from Vifor Pharma; and personal fees from Amgen, Bayer, Novartis, Abbott Vascular, Boehringer Ingelheim, Merck, Pfizer, Servier, AstraZeneca, Berlin Chemie, Cibiem, Renal Guard Solutions Bristol-Myers Squibb, and Impulse Dynamics.

“Iron deficiency should be searched in patients hospitalized with acute heart failure — assessed using a simple blood test — and is now an important therapeutic target,” Ponikowski said at the virtual American Heart Association (AHA) Scientific Sessions 2020.
The results were also published simultaneously in The Lancet.
Iron deficiency is present in up to 70% of patients with acute HF and a predictor of poor outcome, independent of anemia and ejection fraction, he noted.
The FAIR-HF, CONFIRM-HF, and EFFECT-HF trials demonstrated that IV iron supplementation improves exercise capacity, symptoms, and quality of life in iron-deficient HF patients.
However, no such benefit was seen with oral IV in the IRONOUT trial. “So it seems if we are to replace iron, it needs to be done using intravenous therapy,” said John McMurray, MD, University of Glasgow, Scotland, who was invited to discuss the results.
He observed that the reduction in HF hospitalizations in AFFIRM-AHF were relatively modest and that the trial was never expected to show a benefit on CV mortality. Also, the COVID-19 sensitivity analysis providing more convincing effects is a valid approach and one recommended by regulators.
Further, the findings are supported by independent evidence in chronic kidney disease, from the PIVOTAL trial, that intravenous iron reduces HF hospitalizations, McMurray said.
“The million-dollar question, of course, is what will the results of this study mean for the guidelines: I think they probably will change the guidelines,” he said. “Certainly, I hope they will change the US guidelines, which have really given a very lukewarm recommendation for intravenous iron and I think that should probably be stronger.”
In a class IIb recommendation, the 2017 American College of Cardiology/AHA/Heart Failure Society of America heart failure guidelines say intravenous iron “might be reasonable” to improve functional status and quality of life in New York Heart Association class II and III patients with iron deficiency.
The 2016 European Society of Cardiology guidelines include a class IIa recommendation that IV iron “should be considered” in iron-deficient patients with symptomatic HF with reduced ejection fraction.
“This is the first large-scale [trial] of IV supplementation that could potentially change the way we approach patients, particularly those with hospitalized heart failure,” past AHA president Clyde Yancy, MD, MSc, Northwestern University Feinberg School of Medicine in Chicago, said during an earlier press briefing.
He pointed out that clinicians have been circumspect about the early IV iron data. “I have to congratulate you because you’ve changed the narrative,” Yancy said. “We have to start thinking about iron deficiency; we have to think about how we incorporate this in treatment protocols.”
Press briefing panelist Marc Pfeffer, MD, PhD, Brigham and Women’s Hospital and Harvard Medical School in Boston, acknowledged he was among those circumspect.
“I’m no longer a skeptic and I want to congratulate them for showing it’s a risk factor,” he said. “It’s one thing to have a risk factor; it’s another to be a modifiable risk factor and I think that’s what’s so exciting about this.”
The double-blind, phase 4 AFFIRM-AHF trial randomly assigned 1132 patients to receive a bolus injection of ferric carboxymaltose or normal saline before hospital discharge for an acute HF episode. Subsequent treatment was given, as needed, up to 24 weeks post-randomization.
At admission, all patients had left ventricular ejection fractions less than 50% and iron deficiency (serum ferritin <100 ng/mL or serum ferritin 100-299 ng/mL if transferrin saturation <20%).
The modified intention-to-treat (mITT) analysis included 558 FCM patients and 550 controls in whom study treatment was started and for whom at least one post-randomization value was available.
Press briefing discussant Nancy Sweitzer, MD, PhD, director of the University of Arizona’s Sarver Heart Center in Tucson, said AFFIRM-AHF is an “important trial likely to change guidelines” and “targeted one of the highest risk populations we have in heart failure.”
Patients with iron deficiency tend to be elderly with more comorbidities, have longer hospital lengths of stay, and higher readmission rates. “So impacting hospitalizations in this population is incredibly impactful,” she said.
“Awareness and assessment of iron deficiency are an important part of inpatient care of patients with ejection fractions less than or equal to 50% and acute decompensated heart failure, and I think all of us in the community need to pay much more attention to this issue.”
As with any new therapy, there are implementation challenges such as how to monitor patients and deliver the therapy in a cost-effective way, Sweitzer said.
The trial focused on the most vulnerable period for HF patients, but these patients should be rechecked every 3 to 4 months for iron deficiency, Ponikowski observed during the briefing.
“This is a modifiable risk factor,” he said. “We only need to remember, we only need to assess it, and we have a very, very simple tool in our hands. We just need to measure two biomarkers, transferrin saturation and ferritin — that’s all.”
Unanswered questions include the mechanism behind the reduction in hospitalization, the relationship of benefit to hemoglobin levels, and whether there is a differential benefit based on age, presence of ischemia, or sex, especially as women tend to be more severely affected by iron deficiency, Sweitzer said.
During the formal presentation, Ponikowski said the primary endpoint was consistent in subgroup analyses across baseline hemoglobin, estimated glomerular filtration rate, and N-terminal pro-brain natriuretic peptide levels, HF etiology, ejection fraction, and whether HF was diagnosed prior to the index hospitalization.
Treatment with FCM was safe, with no significant differences between the FCM and placebo groups in serious adverse events (45% vs 51%) or adverse events leading to study discontinuation (18% vs 17%), he reported. The most common adverse events were cardiac disorders (40.1% vs 44.3%) and infections (18.2% vs 22%).
AFFIRM-AHF is the first of three ongoing mortality and morbidity trials in heart failure with intravenous ferric carboxymaltose; the others are FAIR-HF2 and HEART-FID. Additional insights are also expected next year on intravenous iron isomaltoside from the Scottish-based IRONMAN trial in 1300 HF patients with iron deficiency.
The study was sponsored by Vifor International. Ponikowski has received research grants and personal fees from Vifor Pharma; and personal fees from Amgen, Bayer, Novartis, Abbott Vascular, Boehringer Ingelheim, Merck, Pfizer, Servier, AstraZeneca, Berlin Chemie, Cibiem, Renal Guard Solutions Bristol-Myers Squibb, and Impulse Dynamics.

Iron supplementation reduces heart failure (HF) readmissions in iron-deficient patients hospitalized for acute HF, according to results of the AFFIRM-AHF trial.
After 52 weeks, intravenous ferric carboxymaltose (Ferinject) reduced the risk of total HF hospitalizations and cardiovascular (CV) death by 21% compared with placebo (293 vs 372 events; rate ratio [RR] 0.79; 95% CI, 0.62 - 1.01).
Although the composite primary endpoint failed to achieve statistical significance, it was driven by a significant 26% reduction in the risk of total HF hospital readmissions (P = .013) without an effect on CV mortality (P =.809).
Because the management and follow-up of patients was affected by the COVID-19 pandemic, a prespecified sensitivity analysis was performed that censored patients in each country at the date when its first COVID-19 patient was reported, explained principal investigator Piotr Ponikowski, MD, PhD, Wroclaw Medical University, Wroclaw, Poland.
That analysis revealed a significant 30% reduction in total HF readmissions (P = .005) in patients receiving ferric carboxymaltose (FCM), as well as significant benefits on the primary composite and secondary endpoints.

FROM AHA 2020
GALACTIC-HF: New ‘myotropic’ drug class shows modest HFrEF benefit
Omecamtiv mecarbil, a member of the novel myotropic drug class that improves cardiac performance, safely produced a significant but modest improvement in heart failure events or cardiovascular death in a pivotal trial with HFrEF patients, leaving experts unsure about the role this drug could have on top of an already crowded list of four first-line drug classes for this condition.
“It remains to be investigated and discussed where omecamtiv mecarbil fits in” the overall approach to treating patients with heart failure with reduced ejection fraction (HFrEF), commented Paul Heidenreich, MD, designated discussant for the report at the virtual scientific sessions of the American Heart Association.
Omecamtiv mecarbil (OM) treatment produced a positive result for the study’s primary endpoint, with a 2.1% absolute cut in the combined rate of cardiovascular death, first heart failure hospitalization, or first urgent visit for heart failure compared with placebo during a median follow-up of about 22 months This represented an 8% relative risk reduction, reported John R. Teerlink, MD, at the meeting, and broke down as a 0.6% absolute drop in cardiovascular death compared with the placebo arm, a 0.7% cut in heart failure hospitalization, and a 0.8% drop in urgent outpatient visits for heart failure. Dr. Teerlink and his associates called this benefit “modest” in their simultaneous publication in the New England Journal of Medicine.
Room for a fifth HFrEF drug?
In addition to the limited benefit, another question raised by the trial is how OM would perform when used on top of what is now considered standard, quadruple therapy for most HFrEF patients: a beta-blocker, a mineralocorticoid receptor antagonist, sacubitril-valsartan (Entresto), and an agent from the sodium glucose co-transporter 2 (SGLT2) inhibitor class, specifically dapagliflozin (Farxiga) or empagliflozin (Jardiance). During the period when the new OM trial was run, 2017-2019, the SGLT2 inhibitors had not yet been established as a key part of standard HFrEF treatment, and hence fewer than 3% of enrolled patients were on one of these drugs.
Because of this evidence gap, OM “can’t be across the board a fifth drug on top of standard treatment,” based on the new results, cautioned Dr. Heidenreich, a cardiologist and professor of medicine at Stanford (Calif.) University School of Medicine.
The new evidence for OM’s efficacy is “not compelling” when compared with what dapagliflozin and empagliflozin each showed in recent trials, with the SGLT2 inhibitors producing about a 25% cut compared with placebo in a primary outcome that was similar to the one used in the OM trial, commented Douglas L. Mann, MD, a heart failure physician and professor of medicine at Washington University School of Medicine in St. Louis. “Would OM still show a benefit with an SGLT2 inhibitor? That’s not known” on the basis of the available data, he said in an interview.
A related factor that could influence potential use of OM in routine practice is that with four established, foundational drug classes, adding a fifth drug that will only be available in a branded formulation raises issues of incremental cost and compliance issues, Dr. Mann noted.
The positives of omecamtiv mercarbil
But in addition to its positive result in the GALACTIC-HF trial, treatment with OM showed other attractive characteristics in a study that treated a wide spectrum of 4,120 patients with HFrEF as well as including 4,112 patients randomized to placebo. Most notably, OM had a very clean safety profile, with adverse event rates similar to placebo patients across all adverse event subtypes, as well as causing no drop in blood pressure and actually an average 2.0–mm Hg increase in systolic blood pressure, no increase in potassium, no apparent impact on renal function, and a small but significant decline in N-terminal pro-B-type natriuretic peptide (NT-proBNP) compared with placebo.
This coupled with the novel mechanism of action of OM – direct augmentation of cardiac sarcomere function by increasing myosin attachment to actin – suggests that OM can be safely added on top of existing HFrEF treatment to provide an unique and incremental benefit.
“Other heart failure drugs [like beta-blockers and sacubitril-valsartan] lower blood pressure, so what can happen is that clinicians run out of room to add full dosages” when patients’ pressures fall too low, commented Gregory D. Lewis, MD, head of Heart Failure at Massachusetts General Hospital in Boston. He is principle investigator for another OM trial, METEORIC-HF, which is examining the possible impact of the drug on exercise capacity in a randomized study with about 270 HFrEF patients.
If the METEORIC-HF results can could confirm some of the GALACTIC-HF results that suggested improvements in patient function, the combined data could potentially lead to regulatory approval for U.S. marketing of the drug, Dr. Lewis suggested. Results from that study are expected in 2021, he said in an interview.
The GALACTIC-HF results hinted at possible functional improvement after 24 weeks on treatment among patients who required hospitalization as measured by the Kansas City Cardiomyopathy Questionnaire, which measures quality life. However, this difference failed to meet the study’s prespecified definition of a significant effect.
Another intriguing suggestion of focused benefit was in patients with a left ventricular ejection fraction at or below the median in GALACTIC-HF of 28%. In that subgroup, OM treatment was linked with a significant 16% relative reduction in the primary endpoint compared with placebo, while it had no significant effect in the other 50% of patients with higher ejection fractions. (The maximum left ventricular ejection fraction for enrollment was 35%.) This apparent subgroup interaction was statistically significant, reported Dr. Teerlink, a professor of medicine at the University of California, San Francisco, and director of Heart Failure at the San Francisco V.A. Medical Center.
Further analysis of the study data “will provide greater insight into subgroups who may demonstrate greater benefit, such as patients with lower ejection fraction in whom improving cardiac function may have a greater role,” he said. The idea that a drug that improves myocyte function at the molecular level could especially benefit patients with the lowest ejection fractions is “biologically plausible,” Dr. Teerlink said.
This scenario looks reasonable, and could make OM something of a niche drug for at least the near term, said Dr. Mann.
The world’s first myotropic drug
Possibly the most notable aspect of GALACTIC-HF is that it proved the efficacy, modest though it was, of a novel drug mechanism that fulfills a decades-long quest of heart failure researchers: a safe way to improve the heart’s pumping action.
“For years, the heart failure community struggled with treatment to improve cardiac performance, but invariably it ended in disaster by worsening cardiac deaths,” problems that led to abandonment of early inotropic drugs more than a generation ago, noted Dr. Mann.
But a more nuanced approach to inotropic agents recently has emerged from Dr. Teerlink and his associates, built on the premise that the dangers seen years ago related to the calcium modulations they caused. Their new paradigm is that the dangers of these “calcitropic” agents can be sidestepped with different agents that either mediate their effects via myosin, the myotropes like OM, or mitochondrial effects from mitotropic drugs.
The inotrope debacle from the 1990s made that drug-class name “a dirty word that causes fear and loathing in the heart failure community,” observed Dr. Mann. While the term myotrope has not yet really caught on, “If omecamtiv mecarbil starts getting used in routine practice, then I think you’ll start seeing uptake of the term myotrope,” he predicted.
GALACTIC-HF was sponsored by Amgen, Cytokinetics, and Servier, the companies developing omecamtiv mecarbil. Dr. Teerlink has received research support from and been a consultant to Amgen, Cytokinetics, and Servier, as well as Abbott, AstraZeneca, Bayer, Boehringer Ingelheim, Bristol-Myers Squibb, Medtronic, Merck, and Novartis. Dr. Heidenreich had no disclosures. Dr. Mann is on a steering committee for a trial sponsored by Novartis and has no other commercial disclosures. Dr. Lewis is principal investigator for a trial of omecamtiv mecarbil and has no other commercial disclosures.

The new evidence for OM’s efficacy is “not compelling” when compared with what dapagliflozin and empagliflozin each showed in recent trials, with the SGLT2 inhibitors producing about a 25% cut compared with placebo in a primary outcome that was similar to the one used in the OM trial, commented Douglas L. Mann, MD, a heart failure physician and professor of medicine at Washington University School of Medicine in St. Louis. “Would OM still show a benefit with an SGLT2 inhibitor? That’s not known” on the basis of the available data, he said in an interview.
A related factor that could influence potential use of OM in routine practice is that with four established, foundational drug classes, adding a fifth drug that will only be available in a branded formulation raises issues of incremental cost and compliance issues, Dr. Mann noted.
The positives of omecamtiv mercarbil
But in addition to its positive result in the GALACTIC-HF trial, treatment with OM showed other attractive characteristics in a study that treated a wide spectrum of 4,120 patients with HFrEF as well as including 4,112 patients randomized to placebo. Most notably, OM had a very clean safety profile, with adverse event rates similar to placebo patients across all adverse event subtypes, as well as causing no drop in blood pressure and actually an average 2.0–mm Hg increase in systolic blood pressure, no increase in potassium, no apparent impact on renal function, and a small but significant decline in N-terminal pro-B-type natriuretic peptide (NT-proBNP) compared with placebo.
This coupled with the novel mechanism of action of OM – direct augmentation of cardiac sarcomere function by increasing myosin attachment to actin – suggests that OM can be safely added on top of existing HFrEF treatment to provide an unique and incremental benefit.
“Other heart failure drugs [like beta-blockers and sacubitril-valsartan] lower blood pressure, so what can happen is that clinicians run out of room to add full dosages” when patients’ pressures fall too low, commented Gregory D. Lewis, MD, head of Heart Failure at Massachusetts General Hospital in Boston. He is principle investigator for another OM trial, METEORIC-HF, which is examining the possible impact of the drug on exercise capacity in a randomized study with about 270 HFrEF patients.
If the METEORIC-HF results can could confirm some of the GALACTIC-HF results that suggested improvements in patient function, the combined data could potentially lead to regulatory approval for U.S. marketing of the drug, Dr. Lewis suggested. Results from that study are expected in 2021, he said in an interview.
The GALACTIC-HF results hinted at possible functional improvement after 24 weeks on treatment among patients who required hospitalization as measured by the Kansas City Cardiomyopathy Questionnaire, which measures quality life. However, this difference failed to meet the study’s prespecified definition of a significant effect.
Another intriguing suggestion of focused benefit was in patients with a left ventricular ejection fraction at or below the median in GALACTIC-HF of 28%. In that subgroup, OM treatment was linked with a significant 16% relative reduction in the primary endpoint compared with placebo, while it had no significant effect in the other 50% of patients with higher ejection fractions. (The maximum left ventricular ejection fraction for enrollment was 35%.) This apparent subgroup interaction was statistically significant, reported Dr. Teerlink, a professor of medicine at the University of California, San Francisco, and director of Heart Failure at the San Francisco V.A. Medical Center.
Further analysis of the study data “will provide greater insight into subgroups who may demonstrate greater benefit, such as patients with lower ejection fraction in whom improving cardiac function may have a greater role,” he said. The idea that a drug that improves myocyte function at the molecular level could especially benefit patients with the lowest ejection fractions is “biologically plausible,” Dr. Teerlink said.
This scenario looks reasonable, and could make OM something of a niche drug for at least the near term, said Dr. Mann.
The world’s first myotropic drug
Possibly the most notable aspect of GALACTIC-HF is that it proved the efficacy, modest though it was, of a novel drug mechanism that fulfills a decades-long quest of heart failure researchers: a safe way to improve the heart’s pumping action.
“For years, the heart failure community struggled with treatment to improve cardiac performance, but invariably it ended in disaster by worsening cardiac deaths,” problems that led to abandonment of early inotropic drugs more than a generation ago, noted Dr. Mann.
But a more nuanced approach to inotropic agents recently has emerged from Dr. Teerlink and his associates, built on the premise that the dangers seen years ago related to the calcium modulations they caused. Their new paradigm is that the dangers of these “calcitropic” agents can be sidestepped with different agents that either mediate their effects via myosin, the myotropes like OM, or mitochondrial effects from mitotropic drugs.
The inotrope debacle from the 1990s made that drug-class name “a dirty word that causes fear and loathing in the heart failure community,” observed Dr. Mann. While the term myotrope has not yet really caught on, “If omecamtiv mecarbil starts getting used in routine practice, then I think you’ll start seeing uptake of the term myotrope,” he predicted.
GALACTIC-HF was sponsored by Amgen, Cytokinetics, and Servier, the companies developing omecamtiv mecarbil. Dr. Teerlink has received research support from and been a consultant to Amgen, Cytokinetics, and Servier, as well as Abbott, AstraZeneca, Bayer, Boehringer Ingelheim, Bristol-Myers Squibb, Medtronic, Merck, and Novartis. Dr. Heidenreich had no disclosures. Dr. Mann is on a steering committee for a trial sponsored by Novartis and has no other commercial disclosures. Dr. Lewis is principal investigator for a trial of omecamtiv mecarbil and has no other commercial disclosures.
