VTE risk after gynecologic surgery lower with laparoscopic procedures
The retrospective cohort study looked at data from 37,485 patients who underwent 43,751 gynecologic surgical procedures, including hysterectomy and myomectomy, at two tertiary care academic hospitals.
Overall, 96 patients (0.2%) were diagnosed with postoperative venous thromboembolism. However patients who underwent laparoscopic or vaginal surgery had a significant 78% and 93% lower risk of venous thromboembolism, respectively, than those who underwent laparotomy, even after adjusting for potential confounders such as age, cancer, race, pharmacologic thromboprophylaxis, and surgical time.
The incidence of postoperative thromboembolism was significantly higher among patients undergoing gynecologic surgery for cancer (1.1%). The incidence among those undergoing surgery for benign indications was only 0.2%, and the highest incidence was among patients with cancer who underwent laparotomy (2.2%).
“This study adds to data demonstrating that venous thromboembolism is rare in gynecologic surgery, particularly when a patient undergoes a minimally invasive procedure for benign indications,” wrote Dr. Elisa M. Jorgensen of Beth Israel Deaconess Medical Center, and her coauthors.
Among the 8,273 patients who underwent a hysterectomy, there were 55 cases of venous thromboembolism – representing an 0.7% incidence. However patients who underwent laparotomy had a 1% incidence of postoperative venous thromboembolism, while those who underwent laparoscopic hysterectomy had an 0.3% incidence and those who underwent vaginal hysterectomy had an 0.1% incidence.
Laparotomy was the most common mode of surgery for hysterectomy – accounting for 57% of operations – while 34% were laparoscopic and 9% were vaginal.
However, the authors noted that the use of laparoscopy increased and laparotomy declined over the 9 years of the study. In 2006, 12% of hysterectomies were laparoscopic, compared with 55% in 2015, while over that same period the percentage of laparotomies dropped from 74% to 41%, and the percentage of vaginal procedures declined from 14% to 4%.
“Because current practice guidelines do not account for mode of surgery, we find them to be insufficient for the modern gynecologic surgeon to counsel patients on their individual venous thromboembolism risk or to make ideal decisions regarding selection of thromboprophylaxis,” Dr. Jorgenson and her associates wrote.
Only 5 patients of the 2,851 who underwent myomectomy developed postoperative VTE – an overall incidence of 0.2% – and the authors said numbers were too small to analyze. Vaginal or hysteroscopic myomectomy was the most common surgical method, accounting for 62% of procedures, compared with 23% for laparotomies and 15% for laparoscopies.
More than 90% of patients who experienced postoperative thromboembolism had received some form of thromboprophylaxis before surgery, either mechanical, pharmacologic, or both. In comparison, only 55% of the group who didn’t experience thromboembolism had received thromboprophylaxis.
“The high rate of prophylaxis among patients who developed postoperative venous thromboembolism may reflect surgeons’ abilities to preoperatively identify patients at increased risk, guiding appropriate selection of thromboprophylaxis,” Dr. Jorgenson and her associates wrote.
Addressing the study’s limitations, the authors noted that they were not able to capture data on patients’ body mass index and also were unable to account for patients who might have been diagnosed and treated for postoperative VTE at other hospitals.
No conflicts of interest were declared.

The aim of this study was to determine the 3-month postoperative incidence of venous thromboembolism among patients undergoing gynecologic surgery. The study also addressed the mode of surgery to allow a comparison between laparotomy and minimally invasive approaches.
Postoperative VTE was defined as deep venous thrombosis of the lower extremities, pulmonary embolism, or both that occurred within 90 days of surgery. A key component of the study was that clinically recognized VTEs that required treatment with anticoagulation, vena caval filter, or both were included.
The study evaluated 43,751 gynecological cases among 37,485 patients. As expected, 59% of the cases were classified as vaginal surgery, 24% were laparoscopic cases, and 17% of the cases were laparotomies.
Of the 8,273 hysterectomies, 57% were via an abdominal approach, 34% were laparoscopic, and 9 were vaginal cases.
Overall, 0.2% of patients were diagnosed with a VTE. As expected, the greatest incidence of VTE was in patients with cancer who underwent a laparotomy. Those with a VTE were significantly more likely to have had an inpatient stay (longer than 24 hours), a cancer diagnosis, a longer surgical time, and an American Society of Anesthesiologists score of 3 or more. They also were older (mean age 56 years vs. 44 years). Of note, 20% of the VTE group identified as black.
Among patients who had a hysterectomy, there were VTEs in 0.7%: 1% in the laparotomy group, 0.3% in the laparoscopic group, and only 0.1% in the vaginal hysterectomy group.
It is interesting to note that 91% of the patients diagnosed with a VTE did received preoperative VTE prophylaxis. The authors noted that the high rate of prophylaxis may have reflected the surgeon’s ability to identify patients who are at high risk.
The authors recognized that the current guidelines do not stratify VTE risk based on the mode of surgery. Further, they noted that low-risk patients undergoing low-risk surgery may be receiving pharmacologic VTE prophylaxis, thus placing these patients at risk for complications related to such therapy.
This paper by Jorgensen et al. should remind us that VTE prophylaxis should be individualized. Patients may not fit nicely into boxes on our EMR; each clinical decision should be made for each patient and for each clinical scenario. The surgeon’s responsibility is to adopt the evidence-based guidelines that serve each individual patient’s unique risk/benefit profile.

Transition to high-sensitivity troponin T assay helped boost ED discharge rates
SAN DIEGO – After transitioning to using the high-sensitivity troponin T assay for patients over the age of 35 years who presented to the ED with chest pain or tightness, an increased number of patients were discharged, yet no impact was observed on the time to admission and/or observation, according to a study conducted at two Philadelphia-based hospitals.
“Biomarkers have been a cornerstone of evaluating patients who present with chest pain,” Frederick T. Randolph, MD, said at the annual meeting of the American College of Emergency Physicians. “Recently in the United States, fifth-generation or high-sensitivity troponin [assays] have been approved for use. Our institution made the plan to transition to utilization of high-sensitivity troponins. At that time, we were aware of European studies that they were able to discharge a higher percentage of patients from the ED. There have been no prior studies of the clinical impact of transition to high-sensitivity troponin [assays] in the U.S.”
Dr. Randolph, director of the Chest Pain Center at Thomas Jefferson University, Philadelphia, and his colleagues performed a before and after study assessing all patients over age 35 years who presented to two hospitals with chest pain or tightness and who received a troponin assay draw in the ED. They conducted two town halls, in-services with cardiology and emergency medicine, and distributed a slide set to all providers. “There was no guidance as to who to order the troponin on,” said Dr. Randolph, who is also vice chief of emergency medicine at the university. “Essentially, the recommendation was, ‘Keep using troponins the same way you’ve been using troponins for years.’ The education was centered on how frequently we were going to order repeat troponins and how to interpret those results.”
The researchers used a 0- and 2-hour sampling strategy (unless the first value was less than 6 ng/L) and used a cut-point of 19 ng/L to define “ruled out” and a cut-point of 53 ng/L to define “consistent with acute myocardial infarction.” Indeterminate values were repeated every 2 hours. Dr. Randolph and his associates collected data for 1 year prior to transition to high-sensitivity troponins in 4,295 patients, and 2 months post transition in 769 patients. The primary outcome was discharge rate from the ED. Secondary outcome was time from presentation to admission/observation decision.
There were no statistically significant differences between the pre- and posttransition groups in the percentage of those aged 36-64 years (74% vs. 76%, respectively) or in the percentage of those who were nonwhite (61% vs. 59%). The only statistically significant difference was a higher percentage of females in the preimplementation group (49% vs. 46%; P = .02).
In all, the researchers were able to discharge 45.2% of all patients during the pretransition period, compared with 58.7% of patients in the posttransition period, for an absolute increase of 13% (P less than .001). There was no difference between the two groups in time to decision to admit or to observe (a mean of 199.1 vs. 192.2 minutes, respectively; P = .96). “Areas of future study would be to evaluate those patients who were discharged and monitor them for any changes in outcomes, to see if there is any increase in morbidity or complications,” said Dr. Randolph. “An additional research curiosity would be the downstream consequences on cost or revenue to the institution given the increased number of admissions and the decreased use of diagnostic testing such as coronary computed tomography angiography and stress testing.”
Dr. Randolph disclosed that some of the study authors have participated in multiple biomarker studies over the years. He reported having no financial disclosures.

Daptomycin/fosfomycin: A new standard for MRSA bacteremia?
SAN FRANCISCO – Daptomycin plus fosfomycin is more effective than daptomycin alone for methicillin-resistant Staphylococcus aureus bacteremia, according to a multicenter, randomized trial from Spain.
“I think this is really an important study; I think it will change clinical practice for this infection” once it’s published, said lead investigator Miquel Pujol, MD, PhD, clinical head of infectious diseases at Bellvitge University Hospital in Barcelona.
The current standard for MRSA bacteremia is daptomycin (Cubicin) or vancomycin (Vancocin) monotherapy on both sides of the Atlantic, but mortality rates are way too high, more than 30% in some reviews. Dr. Pujol and his colleagues wanted to find something better.
Their lab work showed that daptomycin and fosfomycin (Monurol) were synergistic and rapidly bactericidal against MRSA, and anecdotal experience in Spain suggested the drugs improved bacteremia outcomes, so they decided to put the combination to the test.
They randomized 74 MRSA bacteremia patients to the combination, daptomycin 10mg/kg IV daily plus fosfomycin 2g IV q 6h. They randomized 81 other subjects to standard of care with daptomycin monotherapy, also at 10mg/kg IV daily. Treatment was 10-14 days for uncomplicated and 28-42 days for complicated bacteremia.
The open-label trial was conducted at 18 medical centers in Spain, where fosfomycin was discovered in dirt samples in the late 1960s and remains a matter of pride.
At day 7, 69 of the 74 combination patients (93.2%) were alive with clinical improvement, clearance of bacteremia, and no subsequent relapse, versus 62 of 81 patients (76.5%) on monotherapy (absolute difference 16.7%; 95% confidence interval, 5.4%-27.7%). Three people in the combination arm (4.1%) had died by day 7, versus six on monotherapy (7.4%).
Six weeks after the end of treatment at the test-of-cure visit, 40 of 74 combination patients (54.1%) were alive with resolution of all clinical signs and symptoms, negative blood cultures, and no previous or subsequent relapses; just 34 of 81 patients (42%) in the monotherapy arm hit that mark. The 12.1% difference was not statistically significant, nor was the difference in 12-week survival.
However, patients in the combination arm were 70% less likely to have complicated bacteremia at the test-of-cure visit (9.5% vs. 28.4%; relative risk 0.3; 95% CI, 0.2-0.7). There were no cases of persistent or recurrent infection in the combination arm, but nine persistent (11.1%) and five recurrent (6.2%) cases with daptomycin monotherapy. The differences were statistically significant.
The subjects all had at least one positive MRSA blood culture within 72 hours of randomization. Exclusion criteria included MRSA pneumonia, prosthetic valve endocarditis, end-stage liver disease, and moderate to severe heart failure.
There were no significant baseline differences between the groups. About half the subjects were men, and the mean age was about 73 years. The mean Charlson Comorbidity Index score was a bit under 4, and the mean Pitt bacteremia score a bit over 1. The leading source of infection was vascular catheter; acquisition was thought to be nosocomial in more than 40% of patients.
There were no discontinuations from drug side effects in the daptomycin arm, but there were five in the combination arm, including two for heart failure, two for respiratory insufficiency, and one for GI bleeding. Even so, the benefit outweighed the risk, Dr. Pujol said.
Intravenous fosfomycin is available in Europe, but the drug is approved in the United States only as an oral formulation. That could change soon; Nabriva Therapeutics plans to file its IV formulation (Contepo) for Food and Drug Administration approval in late 2018.
Though it is not standard of practice yet, the combination is increasingly being used in Spain for MRSA bacteremia, according to Dr. Pujol. “Patients probably need the combination [at least] initially, especially if they have complicated bacteremia” or fail monotherapy, he said at ID week, an annual scientific meeting on infectious diseases.
The work was funded by the Spanish government. Dr. Pujol said he had no relevant disclosures.

SAN FRANCISCO – Daptomycin plus fosfomycin is more effective than daptomycin alone for methicillin-resistant Staphylococcus aureus bacteremia, according to a multicenter, randomized trial from Spain.
“I think this is really an important study; I think it will change clinical practice for this infection” once it’s published, said lead investigator Miquel Pujol, MD, PhD, clinical head of infectious diseases at Bellvitge University Hospital in Barcelona.
The current standard for MRSA bacteremia is daptomycin (Cubicin) or vancomycin (Vancocin) monotherapy on both sides of the Atlantic, but mortality rates are way too high, more than 30% in some reviews. Dr. Pujol and his colleagues wanted to find something better.
Their lab work showed that daptomycin and fosfomycin (Monurol) were synergistic and rapidly bactericidal against MRSA, and anecdotal experience in Spain suggested the drugs improved bacteremia outcomes, so they decided to put the combination to the test.
They randomized 74 MRSA bacteremia patients to the combination, daptomycin 10mg/kg IV daily plus fosfomycin 2g IV q 6h.

FDA clears Abbott’s Influenza A & B 2, Strep A 2 assays
The Food and Drug Administration has cleared Abbott Laboratories’ next-generation Influenza A & B 2 and Strep A 2 molecular assays for point-of-care testing.
The Influenza A & B 2 assay can detect and differentiate influenza A and B in 13 minutes, with a call-out of positive results at 5 minutes. It can be stored at room temperature, simplifying storage and ordering. The Strep A 2 assay detects group A streptococcus bacterial nucleic acid in 6 minutes, with a call-out of positive results at 2 minutes. Both will be the fastest tests currently on the market in their respective fields, according to a corporate press release.
The assays will be available in a variety of inpatient and outpatient settings, particularly in locations where patients commonly access health care services, such as EDs, physician offices, walk-in clinics, and urgent care centers. This will allow health care providers to make a fast, informed diagnosis and provide appropriate treatment within the span of a single patient visit.
“The ability to obtain early call outs for positive test results with molecular accuracy in as little as 5 minutes for influenza and 2 minutes for strep A is a game-changing development that allows prompt treatment decisions at the point of care. Rapid testing may also help reduce improper antibiotic usage, which can occur when treatment is based exclusively on a patient’s symptoms, and contributes to antibiotic resistance,” Gregory J. Berry, PhD, director of molecular diagnostics at Northwell Health Laboratories in Lake Success, N.Y., said in the press release.

Length of stay, complications predict readmission for cirrhosis patients
PHILADELPHIA – Patients with cirrhosis have a higher risk of hospital readmission if their length of stay is less than 4 days, if they have cirrhosis-related complications, and if they are discharged to an extended-care facility or to home health care, according to a recent presentation at the annual meeting of the American College of Gastroenterology.
“The presence of cirrhosis-related complications is very strongly associated with readmissions,” Chandraprakash Umapathy, MD, MS, from the University of California, San Francisco, Fresno, said during his presentation. “Quality improvement efforts should focus on optimizing the management of complications of cirrhosis in the outpatient setting to reduce readmissions.”
In a retrospective cohort study, Dr. Umapathy and colleagues identified 230,036 patients from the Healthcare Cost and Utilization Project National Readmission Database for 2014 who had been discharged with a diagnosis of cirrhosis; of these patients, there were 185,737 index cases after excluding readmissions. Included patients had a mean age of 60.2 years and mean length of stay of 6.4 days, with 46% of patients having a length of stay longer than 4 days and mean total charges of $56,519. With regard to cirrhosis, 55% of patients displayed cirrhosis complications and 6.7% had more than three cirrhosis-related complications; the most common complication was ascites, in 32% of patients.
Overall, 11.09% of patients were readmitted at 30 days and 18.74% of patients were readmitted at 90 days, Dr. Umapathy said. Patients were more likely to be readmitted at 30 days if they were originally admitted on a weekend (adjusted prevalence ratio, 1.06; P = .001); into a medium (1.09; P = .009) or large (1.11; P less than .001) hospital; were admitted at a metropolitan teaching hospital (1.07; P less than .001); were insured by Medicaid (1.07; P less than .001); or were transferred to an extended care (1.51; P less than .001) facility or discharged to home health care (1.43; P less than .001).
Compared with patients who were not readmitted at 30 days, patients with 30-day readmission had a higher rate of alcoholic liver disease (43% vs. 46%; P less than .001), hepatitis C (28% vs. 32%; P less than .001), ascites (31% vs. 43%; P less than .001), hepatic encephalopathy (15% vs. 22%; P less than .001), hepatorenal syndrome (2.3% vs. 4.9%; P less than .001), hepatocellular cancer (5.1% vs. 5.7%; P = .001), presence of any cirrhosis complications (54% vs. 65%; P less than .001), and presence of more than three cirrhosis-related complications (6.3% vs. 10%; P less than .001). When adjusted in a multivariate analysis, association with readmission at 30 days for patients with cirrhosis-related complications such as ascites (1.42; P less than .001), hepatic encephalopathy (1.44; P less than .001), and hepatorenal syndrome (1.34; P less than .001) remained, Dr. Umapathy noted.
Length of stay longer than 4 days (0.84; P less than .001) and variceal hemorrhage (0.74; P = .002) were associated with reduced risk of readmissions at 30 days. “Focus on length of stay may result in patients being discharged prematurely, leading to higher early readmission,” Dr. Umapathy said.
Dr. Umapathy reports no relevant conflicts of interest.

Helping alleviate hospitalist burnout
Focus on systemic factors
For hospitalists, burnout is a widespread and ongoing problem. In 2011, a Mayo Clinic study found that 45% of U.S. physicians had at least one symptom of professional burnout; by 2014, that number had risen to 54%.
“Burnout among physicians has been shown to be linked to quality of care, impacting medical errors, mortality ratios in hospitalized patients, and lower patient satisfaction,” said Ingrid T. Katz, MD, MHS, assistant professor of medicine at Harvard Medical School, Boston, and coauthor of a recent column on the subject published in the New England Journal of Medicine.
Widespread burnout is caused by systemic factors, not individual failures. “These systemic factors range from excessive clerical burden to ‘work beyond work,’ where people end up taking work home at night and are often found interfacing with the EHR well after their normal work day,” Dr. Katz said. “Many also express their disdain for the model of practice that no longer values autonomy, which was seen as inherent in the profession prior to the current model of care.”
Moving towards a better framework would require an inherent trust in physicians, limiting unnecessary intrusions into a physician’s practice that do not impact medical care. “It would remove the burden of excessive documentation and allow for physicians to get reinspired by the practice of medicine, an inherently altruistic profession,” Dr. Katz said.
Changes might include eliminating excessive clerical demands and improving EHRs to allow physicians to return to the bedside. Workloads would be geared towards quality in care and not focused on improving the bottom line of a health care system. One health system Dr. Katz wrote about instituted a team-based model; under this system medical assistants gather data and reconcile medications, allowing physicians to focus on performing physical exams and making medical decisions.
“Burnout will diminish when physicians are empowered to be part of the solution and hospital systems make changes that recognize the totality of the challenges that physicians face,” Dr. Katz said, adding that hospitalists are in a unique position to promote such changes on a systemic level. “Leadership needs to be willing to inform and engage their physicians, monitor well-being of physicians as closely as they monitor quality in care, and implement changes when needed.”

For hospitalists, burnout is a widespread and ongoing problem. In 2011, a Mayo Clinic study found that 45% of U.S. physicians had at least one symptom of professional burnout; by 2014, that number had risen to 54%.
“Burnout among physicians has been shown to be linked to quality of care, impacting medical errors, mortality ratios in hospitalized patients, and lower patient satisfaction,” said Ingrid T. Katz, MD, MHS, assistant professor of medicine at Harvard Medical School, Boston, and coauthor of a recent column on the subject published in the New England Journal of Medicine.
Widespread burnout is caused by systemic factors, not individual failures. “These systemic factors range from excessive clerical burden to ‘work beyond work,’ where people end up taking work home at night and are often found interfacing with the EHR well after their normal work day,” Dr. Katz said. “Many also express their disdain for the model of practice that no longer values autonomy, which was seen as inherent in the profession prior to the current model of care.”
Moving towards a better framework would require an inherent trust in physicians, limiting unnecessary intrusions into a physician’s practice that do not impact medical care. “It would remove the burden of excessive documentation and allow for physicians to get reinspired by the practice of medicine, an inherently altruistic profession,” Dr. Katz said.
Changes might include eliminating excessive clerical demands and improving EHRs to allow physicians to return to the bedside. Workloads would be geared towards quality in care and not focused on improving the bottom line of a health care system. One health system Dr. Katz wrote about instituted a team-based model; under this system medical assistants gather data and reconcile medications, allowing physicians to focus on performing physical exams and making medical decisions.
“Burnout will diminish when physicians are empowered to be part of the solution and hospital systems make changes that recognize the totality of the challenges that physicians face,” Dr. Katz said, adding that hospitalists are in a unique position to promote such changes on a systemic level. “Leadership needs to be willing to inform and engage their physicians, monitor well-being of physicians as closely as they monitor quality in care, and implement changes when needed.”

FDA approves Xofluza for treatment of influenza
The Food and Drug Administration has approved Xofluza (baloxavir marboxil) for the treatment of acute uncomplicated influenza in people aged 12 years or older who have been symptomatic for 48 hours or less.
The FDA approval is based on results from two randomized, clinical trials. In both trials, patients who received Xofluza experienced a shorter duration until alleviation of symptoms, compared with patients who received a placebo. In the second trial, patients who received Xofluza and patients who received another approved antiviral influenza medication experienced similar durations until symptom alleviation.
“When treatment is started within 48 hours of becoming sick with flu symptoms, antiviral drugs can lessen symptoms and shorten the time patients feel sick. Having more treatment options that work in different ways to attack the virus is important because flu viruses can become resistant to antiviral drugs,” Debra Birnkrant, MD, director of the Division of Antiviral Products in the FDA’s Center for Drug Evaluation and Research, said in a press release.
The most common adverse events associated with Xofluza were diarrhea and bronchitis.
“This is the first new antiviral flu treatment with a novel mechanism of action approved by the FDA in nearly 20 years,” FDA Commissioner Scott Gottlieb, MD, added. “With thousands of people getting the flu every year, and many people becoming seriously ill, having safe and effective treatment alternatives is critical. This novel drug provides an important, additional treatment option.”

Study: Problems persist with APMs
Physicians continue to support advanced alternative payment models despite the fact that operational issues have not improved over the last 4 years and new ones have cropped up, according to a follow-up survey conducted by the RAND Corporation for the American Medical Association.
“All the things we heard in 2014 were still present in 2018. Both the challenges that practices had experienced back in 2014 having to do with data timeliness, data completeness and accuracy, payment model execution, all those challenges persisted,” Mark W. Friedberg, MD, senior physician policy researcher at RAND, said in an interview.
RAND surveyed 31 practices of varying practice size and specialty across six geographic regions, some of which participated in the 2014 survey. Supplemental information was provided by interviews with 32 market observers, 8 health plan leaders, 10 hospital and hospital system leaders, 10 state and local medical society leaders, and 4 chapter leaders with MGMA (formerly the Medical Group Management Association).
“We had thought we would hear that the problem had gotten a little bit better since there has been some investment in trying to tamp down the wide range of measures that are involved in these alternative payment models,” Dr. Friedberg said. “We did not see any evidence of that having any effect on the practices that participated in this study this time around.”
Indeed, concerns reported in 2014 were again reported in 2018, along with a new set of concerns, including the perceived pace of change in alternative payment models (APMs), the complexity of APMs, and physician concerns over two-sided risk models.
“Practices, especially those that participated both times, said in 2014 we had these challenges [of rapid changes in APM models] and since then, things have just gotten a lot faster,” he said, noting that doctors are complaining of models that are going through changes, sometimes without much warning. “They are changing quite rapidly from year to year. If you look at the MACRA QPP [Quality Payment Program] for example, that model changes every year to some extent and those things are hard for them to keep up with.”
Running hand in hand with the change is the complexity of the changes, a result of expanding performance measures and uncertainty with thresholds for penalties and rewards and in some ways has had little impact on improving care.
Dr. Friedberg noted that some practices are hiring people to examine APMs to devise strategic ways to choose and report data for maximum return.
“In a practice, for example, if their quality of care was already very good, what these folks ended up doing was help them choose measures and work the attribution algorithms in a strategic way to either guarantee a bonus or minimize the risk of incurring a penalty,” he said.
He also noted that practices appear to becoming more risk averse.
“We heard a lot more of the following thing, which is that if [practices] were in a two-sided risk model, several of them reported trying and succeeding in some cases offloading the downside risk to partners,” Dr. Friedberg reported. “And what this resulted in was that the practice, even though from the payer’s perspective they are in a two-sided model, the practice was actually in a one-sided model with a partner who is taking all of the downside risk and a portion of the upside risk, leaving a small upside risk proposition that remained for the practice.”
He said the range of partners that were absorbing the downside risk included hospitals, device manufacturers, consulting companies, or private equity firms.
Despite the concerns surrounding APMs, Dr. Friedberg said that “we did not hear practices broadly saying that they just weren’t interested in alternative payment models. In general, practices still remained pretty enthusiastic about these alternative payment models in theory. If they could be made simpler, if the pace of change weren’t quite so fast, that they would have a chance to really do some important care improvements in alternative payment models.”
He noted some of the surveyed practices were able to make investments in care as a direct result of participating in APMs, such as in behavioral health capabilities in primary care, for example, leading to quality of care improvements.
However, these issues could reveal a future unwillingness to participate in APMs, especially two-sided risk models, something at least the Centers for Medicare & Medicaid Services are pushing for as a stated goal of the QPP is to get practices to participate in APMs and take on more risk.
The growing aversion to taking on downside risk could lead practices to simply stay in fee for service and simply take the payment penalty because it is a fixed amount that can be planned for, as opposed to the fluctuations of bonuses and penalties that comes with a rapidly changing APM environment, Dr. Friedberg said.
Going forward, the report makes a number of recommendations to help create an environment that would potentially make APMs more successful, including simplifying the models; creating stable, predictable, and moderately paced pathways to APM participation; making data available in a more timely fashion; minimizing downside risk or helping practices better manage it; and designing APMs that will encourage clinical changes to help improve the effectiveness of care delivered.

Stroke risk in elderly following AMI extends to 12 weeks
ATLANTA – Acute myocardial infarction is associated with a risk of stroke that extends beyond the 1-month time window currently considered the at-risk period, according to an analysis of Medicare data.
“The results of our study may allow clinicians to more accurately counsel patients regarding their stroke etiology and may allow refinement of stroke etiology classification systems and clinical trial selection criteria,” lead study author Alexander E. Merkler, MD, said in an interview in advance of the annual meeting of the American Neurological Association.
In an effort to better understand the duration of heightened stroke risk after acute myocardial infarction, Dr. Merkler, a neurologist at New York–based Weill Cornell Medicine, and his colleagues conducted a retrospective cohort study using inpatient and outpatient claims during 2008-2015 from a nationally representative 5% sample of Medicare beneficiaries who were at least 66 years old. They used previously validated ICD-9-CM diagnosis codes to ascertain the exposure variable of acute MI and the outcome of ischemic stroke but excluded strokes that occurred during an acute MI hospitalization.
Patients were censored at the time of ischemic stroke, death, end of Medicare coverage, or by Sept. 30, 2015. The researchers fit Cox regression models separately for the groups with and without acute MI to examine its association with ischemic stroke after adjusting for demographics, stroke risk factors, and Charlson comorbidities. Next, they used the corresponding survival probabilities to compute the hazard ratio (HR) in each 4-week interval after discharge, up to week 12. They also conducted a subgroup analysis to evaluate the duration of heightened ischemic stroke risk by MI type: ST-segment elevation MI (STEMI) versus non-STEMI (NSTEMI).
Dr. Merkler and his colleagues drew from data on 1.7 million eligible beneficiaries. Of these, 46,182 were hospitalized for acute MI and 80,466 for ischemic stroke. After they adjusted for demographics, stroke risk factors, and Charlson comorbidities, the researchers found that the risk of ischemic stroke was highest in the first 4 weeks after discharge from the MI hospitalization (HR, 2.7), yet remained elevated during weeks 5-8 (HR, 2.0) and weeks 9-12 (HR, 1.6). It was no longer significantly elevated afterward. The prolonged period of heightened ischemic stroke risk was evident in patients with both STEMI and NSTEMI.
“We were surprised by how long the risk of stroke lasts after MI,” Dr. Merkler said. He acknowledged certain limitations of the analysis, including the fact that patients were all over the age of 65 years. “In addition, we lack granular detail such as severity of MI [and] the extent of stroke work-up,” he said.
Dr. Merkler disclosed that he is supported by a grant from the National Institutes of Health and by the Leon Levy Foundation in Neuroscience. Most of his coauthors are also supported by NIH grants.

Drug overdose deaths down since late 2017
Longer-term data, however, show an increase over the year from March 2017 to March 2018, as the short-term decrease was not enough to overcome the previous year’s increase. The provisional 12-month ending count – deaths during the 12-month period ending in the month indicated – went from 66,859 in March 2017 to 68,690 in March 2018, an increase of 2.7%, the NCHS reported.
That year-long increase was not spread evenly among the states. Nebraska’s 12-month ending count jumped over 48% from March 2017 to March 2018, more than twice as much as second-place Hawaii’s 20.9%. Montana had the largest drop over that year, –24.2%, with Wyoming next at –20.7% and the District of Columbia third at –14.8%, data from the National Vital Statistics System show.
“Provisional drug overdose death data are often incomplete,” the NCHS noted, “and the degree of completeness varies by jurisdiction and 12-month ending period. Consequently, the numbers of drug overdose deaths are underestimated, based on provisional data relative to final data and are subject to random variation.”
