ATLANTA – An asthma medication ratio below 0.5 nearly doubles the risk of children ending up in the hospital with an acute asthma exacerbation, according to researchers from the Medical University of South Carolina (MUSC), Charleston.

The asthma medication ratio (AMR) – the number of prescriptions for controller medications divided by the number of prescriptions for both controller and rescue medications – has been around for a while, but it’s mostly been used as a quality metric. The new study shows that it’s also useful in the clinic to identify children who could benefit from extra attention.

A perfect ratio of 1 means that control is good without rescue inhalers. The ratio falls as the number of rescue inhalers goes up, signaling poorer control. Children with a ratio below 0.5 are considered high risk; they’d hit that mark if, for instance, they were prescribed one control medication such as fluticasone propionate (Flovent) and two albuterol rescue inhalers in a month.

If control is good, “you should only need a rescue inhaler very, very sporadically;” high-risk children probably need a higher dose of their controller, or help with compliance, explained lead investigator Annie L. Andrews, MD, associate professor of pediatrics at MUSC.

The university uses the EPIC records system, which incorporates prescription data from Surescripts, so the number of asthma medication fills is already available. The system just needs to be adjusted to calculate and report AMRs monthly, something Dr. Andrews and her team are working on. “The information is right there, but it’s an untapped resource,” she said. “We just need to crunch the numbers, and operationalize it. Why are we waiting until kids are in the hospital” to intervene?

Dr. Andrews presented a proof-of-concept study at the Pediatric Hospital Medicine meeting. Her team identified 214,452 asthma patients aged 2-17 years with at least one claim for an inhaled corticosteroid in the Truven MarketScan Medicaid database from 2013-14.

They calculated AMRs for each child every 3 months over a 15-month period. About 9% of children at any given time had AMRs below 0.5.

The first AMR was at or above 0.5 in 93,512 children; 18.1% had a subsequent asthma-related event, meaning an ED visit or hospitalization, during the course of the study. Among the 17,635 children with an initial AMR below 0.5, 25% had asthma-related events. The initial AMR couldn’t be calculated in 103,305 children, which likely meant they had less-active disease. Those children had the lowest proportion of asthma events, at 13.9%.

An AMR below 0.5 nearly doubled the risk of an asthma-related hospitalization or ED visit in the subsequent 3 months, with an odds ratios ranging from 1.7 to 1.9, compared with other children. The findings were statistically significant.

In short, serial AMRs helped predict exacerbations among Medicaid children. The team showed the same trend among commercially insured children in a recently published study. The only difference was that Medicaid children had a higher proportion of high-risk AMRs, and a higher number of asthma events (Am J Manag Care. 2018 Jun;24[6]:294-300). Together, the studies validate “the rolling 3-month AMR as an appropriate method for identifying children at high risk for imminent exacerbation,” the investigators concluded.

With automatic AMR reporting already in the works at MUSC, “we are now trying to figure out how to intervene. Do we just tell providers who their high-risk kids are and let them figure out how to contact families, or do we use this information to contact families directly? That’s kind of what I favor: ‘Hey, your kid just popped up as high risk, so let’s figure out what you need. Do you need a new prescription or a reminder to see your doctor?’ ” Dr. Andrews said.

Her team is developing a mobile app to communicate with families.

The mean age in the study was 7.9 years; 59% of the children were boys, and 41% were black.

The work was funded by the National Institutes of Health, among others. Dr. Andrews had no disclosures. The meeting was sponsored by the Society of Hospital Medicine, the American Academy of Pediatrics, and the Academic Pediatric Association.

Background: While there is a consensus on the need for chemoprophylaxis to reduce the rates of postoperative VTE, there is wide variation in choice of agents recommended. Aspirin, while cheap and widely available, has never been directly compared with a direct oral anticoagulant in randomized, controlled trials.

Study design: Multicenter, double-­blind, randomized, controlled noninferiority trial.

Setting: 15 university-affiliated health centers in Canada from January 2013 through April 2016.

Synopsis: 3,224 patients who received daily rivaroxaban for 5 days following joint arthroplasty were randomized to either receive aspirin 81 mg daily or continue daily rivaroxaban. Duration of therapy was determined by type of surgery (9 days for knee, 17 days for hip). The primary effectiveness outcome was defined as symptomatic pulmonary embolism or proximal deep venous thrombosis diagnosed in the 90-day follow-up period. The primary outcome results met the predetermined criterion for noninferiority with similar rates of symptomatic VTE in the aspirin and rivaroxaban group (0.64% vs. 0.7%; P less than .001). There was no significant difference in bleeding rates between the groups. Given that patients with prior VTE, morbid obesity, or cancer were not well represented in this study, these results should not be extrapolated to those populations felt to be at highest risk for VTE.

Bottom line: For thromboprophylaxis after joint arthroplasty, rivaroxaban followed by aspirin may be noninferior to extended rivaroxaban.

ATLANTA – A short course of IV antibiotics – 7 days or less – is fine for most infants with uncomplicated bacteremic urinary tract infections, according to a review of 116 children younger than 60 days.

How long to treat bacteremic UTIs in the very young has been debated in pediatrics for a while, with some centers opting for a few days and others for 2 weeks or more. Shorter courses reduce length of stay, costs, and complications, but there hasn’t been much research to see whether they work as well.

The new investigation has suggested they do. “Young infants with bacteremic UTI who received less than or equal to 7 days of IV antibiotic therapy did not have more recurrent UTIs,” compared “to infants who received longer courses. Short course IV therapy with early conversion to oral antibiotics may be considered in this population,” said lead investigator Sanyukta Desai, MD, at the Pediatric Hospital Medicine meeting.

The team compared outcomes of 58 infants treated for 7 days or less to outcomes of 58 infants treated for more than 7 days at 11 children’s hospitals scattered across the United States.

Urine was collected by catheter, and each child grew the same organism in their blood and urine cultures, confirming the diagnosis of bacteremic UTI. Children with bacterial meningitis, or suspected of having it, were excluded. The subjects had all been admitted through the ED.

There was quite a bit of variation among the 11 hospitals, with the proportion of children treated with short courses ranging from 10% to 81%.

As for the results, two patients in the short-course group (3%) and four in the long-course group (7%) had recurrent UTIs within 30 days. None of them developed meningitis, and none required ICU admission. Propensity-score matching revealed an odds ratio for recurrence that favored shorter treatment, but it wasn’t statistically significant.

The mean length of stay was 5 days in the short-course arm and 11 days in the long-course arm. There were no serious adverse events within 30 days of the index admission in either group.

Among the recurrences, the two children in the short-course arm were initially treated for 3 and 5 days. Both were older than 28 days at their initial presentation, and both had vesicoureteral reflux of at least grade 2, which was not diagnosed in one child until after the recurrence. The other child had been on prophylactic trimethoprim/sulfamethoxazole before the recurrence.

The four recurrent cases in the long arm initially received either 10 or 14 days of IV antibiotics. Two children had grade 4 vesicoureteral reflux and had been on prophylactic amoxicillin.

Infants treated with longer antibiotic courses were more likely to be under 28 days old, appear ill at presentation, have had bacteremia for more than 24 hours, and have and grow out pathogens other than Escherichia coli. The two groups were otherwise balanced for sex, prematurity, complex chronic conditions, and known genitourinary anomalies.

With such low event rates, the study wasn’t powered to detect small but potentially meaningful differences in outcomes, and further work is needed to define which children would benefit from longer treatment courses. Even so, “it was reassuring that patients did well in both arms,” said Dr. Desai, a clinical fellow in the division of hospital medicine at Cincinnati Children’s Hospital.

“At our institution with uncomplicated UTI, we wait to see what the culture grows.” If there’s an oral antibiotic that will work, “we send [infants] home in 3-4 days. We haven’t had any poor outcomes, even when they’re bacteremic,” she said.

The work was funded by the National Institutes of Health. The investigators didn’t have any disclosures.

Certain procedures conducted in the hospital outpatient setting could see a reimbursement cut to levels paid for under the physician fee schedule if a proposal introduced by the Centers for Medicare & Medicaid Services is finalized.

In the proposed update to the Outpatient Prospective Payment System (OPPS) for 2019, released July 27 and scheduled to be published July 31 in the Federal Register, the CMS is proposing to apply a physician fee schedule–equivalent for the clinic visit service when provided at an off-campus, provider-based department that is paid under the OPPS.

“The clinic visit is the most common service billed under the OPPS and is often furnished in the physician office setting,” the CMS said in a fact sheet detailing its proposal.

According to the CMS, the average current clinical visit paid by the CMS is $116 with $23 being the average copay by the patient. If the proposal is finalized, the payment would drop to about $46 with an average patient copay of $9.

“This is intended to address concerns about recent consolidations in the market that reduce competition,” CMS Administrator Seema Verma said during a July 25 press conference.

The American Hospital Association already is pushing back on this proposal.

“With today’s proposed rule, CMS has once again showed a lack of understanding about the reality in which hospitals and health systems operate daily to serve the needs of their communities,” AHA Executive Vice President Tom Nickels said in a statement. “In 2015, Congress clearly intended to provide current off-campus hospital clinics with the existing outpatient payment rate in recognition of the critical role they play in their communities. But CMS’s proposal runs counter to this and will instead impede access to care for the most vulnerable patients.”

However, Farzad Mostashari, MD, founder of the health care technology company Aledade and National Coordinator for Health IT under President Obama, suggested that this could actually be a good thing for hospitals.

“The truth is that this proposal could help hospitals be more competitive in value-based contracts/alternative-payment models, and they should embrace the changes,” he said in a tweet.

The OPPS update also includes proposals to expand the list of covered surgical procedures that can be performed in an ambulatory surgical center, a move that Ms. Verma said would “provide patients with more choices and options for lower-priced care.”

“For CY 2019, CMS is proposing to allow certain CPT codes outside of the surgical code range that directly crosswalk or are clinically similar to procedures within the CPT surgical code range to be included on the [covered procedure list] and is proposing to add certain cardiovascular codes to the ASC [covered procedure list] as a result,” the CMS fact sheet notes.

The CMS also will review all procedures added to the covered procedure list in the past 3 years to determine whether such procedures should continue to be covered.

In addition, the OPPS is seeking feedback on a number of topics.

One is related to price transparency. The agency is asking “whether providers and suppliers can and should be required to inform patients about charges and payment information for healthcare services and out-of-pocket costs, what data elements the public would find most useful, and what other charges are needed to empower patients,” according to the fact sheet.

“For CY 2019, CMS is proposing to allow certain CPT codes outside of the surgical code range that directly crosswalk or are clinically similar to procedures within the CPT surgical code range to be included on the [covered procedure list] and is proposing to add certain cardiovascular codes to the ASC [covered procedure list] as a result,” the CMS fact sheet notes.

The CMS also will review all procedures added to the covered procedure list in the past 3 years to determine whether such procedures should continue to be covered.

In addition, the OPPS is seeking feedback on a number of topics.

One is related to price transparency. The agency is asking “whether providers and suppliers can and should be required to inform patients about charges and payment information for healthcare services and out-of-pocket costs, what data elements the public would find most useful, and what other charges are needed to empower patients,” according to the fact sheet.

Certain procedures conducted in the hospital outpatient setting could see a reimbursement cut to levels paid for under the physician fee schedule if a proposal introduced by the Centers for Medicare & Medicaid Services is finalized.

In the proposed update to the Outpatient Prospective Payment System (OPPS) for 2019, released July 27 and scheduled to be published July 31 in the Federal Register, the CMS is proposing to apply a physician fee schedule–equivalent for the clinic visit service when provided at an off-campus, provider-based department that is paid under the OPPS.

“The clinic visit is the most common service billed under the OPPS and is often furnished in the physician office setting,” the CMS said in a fact sheet detailing its proposal.

According to the CMS, the average current clinical visit paid by the CMS is $116 with $23 being the average copay by the patient. If the proposal is finalized, the payment would drop to about $46 with an average patient copay of $9.

“This is intended to address concerns about recent consolidations in the market that reduce competition,” CMS Administrator Seema Verma said during a July 25 press conference.

The American Hospital Association already is pushing back on this proposal.

“With today’s proposed rule, CMS has once again showed a lack of understanding about the reality in which hospitals and health systems operate daily to serve the needs of their communities,” AHA Executive Vice President Tom Nickels said in a statement. “In 2015, Congress clearly intended to provide current off-campus hospital clinics with the existing outpatient payment rate in recognition of the critical role they play in their communities. But CMS’s proposal runs counter to this and will instead impede access to care for the most vulnerable patients.”

However, Farzad Mostashari, MD, founder of the health care technology company Aledade and National Coordinator for Health IT under President Obama, suggested that this could actually be a good thing for hospitals.

“The truth is that this proposal could help hospitals be more competitive in value-based contracts/alternative-payment models, and they should embrace the changes,” he said in a tweet.

The OPPS update also includes proposals to expand the list of covered surgical procedures that can be performed in an ambulatory surgical center, a move that Ms. Verma said would “provide patients with more choices and options for lower-priced care.”

Patients with both chronic obstructive pulmonary disease (COPD) and heart failure (HF) are prone to hospital readmissions that detract from quality of life and dramatically drive up care costs.

Because the two chronic diseases spring from the same root cause and share overlapping symptoms, strategies that improve clinical outcomes in one can also benefit the other, Ravi Kalhan, MD, and R. Kannan Mutharasan, MD, wrote in CHEST Journal (doi: 10.1016/j.chest.2018.06.001).

“Both conditions are characterized by periods of clinical stability punctuated by episodes of exacerbation and are typified by gradual functional decline,” wrote the colleagues, both of Northwestern University, Chicago. “From a patient perspective, both conditions lead to highly overlapping patterns of symptoms, involve complicated medication regimens, and have courses highly sensitive to adherence and lifestyle modification. Therefore, disease management strategies for both conditions can be synergistic.”

The team came up with a “Top 10 list” of practical tips for reducing readmissions in patients with this challenging combination.
 

Diagnose accurately

An acute hospitalization is often the first time these patients pop up on the radar. This is a great time to employ spirometry to accurately diagnose COPD. It’s also appropriate to conduct a chest CT and check right heart size, diameter of the pulmonary artery, and the presence of coronary calcification. The authors noted that relatively little is known about the course of patients with combined asthma and HF in contrast to COPD and HF.

Detect admissions for exacerbations early

Check soon to find out if this is a readmission, get an acute plan going, and don’t wait to implement multidisciplinary interventions. “First, specialist involvement can occur more rapidly, allowing for faster identification of any root causes driving the HF or COPD syndromes, and allowing for more rapid institution of treatment plans to control the acute exacerbation. Second, early identification during hospitalization allows time to deploy multidisciplinary interventions, such as disease management education, social work evaluation, follow-up appointment scheduling, and coordination of home services. These interventions are less effective, and are often not implemented, if initiated toward the end of hospitalization.”

Use specialist management in the hospital

Get experts on board fast. An integrated team means a coordinated treatment plan that’s easier to follow and more effective therapeutically. Specialist care may impact rates of readmission: weight loss with diuretics; discharge doses of guideline-directed medical therapy for heart failure; and higher rates of discharge on long-acting beta-agonists, long-acting muscarinic antagonists, inhaled corticosteroids, and home supplemental oxygen.

Modify the underlying disease substrate

Heart failure is more likely to arise from a correctable pathophysiology, so find it early and treat it thoroughly – especially in younger patients. Ischemic heart disease, valvular heart disease, systemic hypertension, and pulmonary hypertension all have potential to make the HF syndrome more tractable.

Apply and intensify evidence-based therapies

Start in the hospital if possible; if not, begin upon discharge. “The order of application of these therapies can be bewildering, as many strategies for initiation and up-titration of these medications are reasonable. Not only are there long-term outcome benefits for these therapies, evidence suggests early initiation of HF therapies can reduce 30-day readmissions.”

Activate the patient and develop critical health behaviors

Medical regimens for these diseases can be complex, and they must be supported by patient engagement. “Many strategies for engaging patients in care have been tested, including teaching to goal, motivational interviewing, and teach-back methods of activation and engagement. Often these methods are time intensive. Because physician time is increasingly constrained, a team approach is particularly useful.”

Set up feedback loops

“Course correction should the patient decompensate is critically important to maintaining outpatient success. Feedback loops can allow for clinical stabilization before rehospitalization is necessary.” Self-monitoring with individually set benchmarks is critical.

Arrange an early follow-up appointment prior to discharge

About half of Medicare patients with these conditions are readmitted before they’ve even had a postdischarge follow-up appointment. Ideally this should occur within 7 days. The purpose of early follow-up is to identify and address gaps in the discharge plan of care, revise the discharge plan of care to adapt to the outpatient environment, and reinforce critical health behaviors.

Consider and address other comorbidities

Comorbidities are the rule rather than the exception and contribute to many readmissions. Get primary care on the team and enlist their help in managing these issues before they lead to an exacerbation. “Meticulous control – even perfect control were it possible – of cardiopulmonary disease would still leave patients vulnerable to significant risk of readmission from other causes.”

Consider ancillary supportive services at home

Patients may be overwhelmed by the complexity of postdischarge care. Home health assistance can help in getting patients to physical therapy, continuing patient education, and providing a home clinical assessment.

Neither of the authors had any financial disclosures.

MALMO, SWEDEN – Ultrasound of the kidneys and urinary tract in the acute phase of a first urinary tract infection in young children has an unacceptably high false-positive rate, Magdalena Okarska-Napierala, MD, reported at the annual meeting of the European Society for Paediatric Infectious Diseases.

Bruce Jancin/MDedge News

“Sonography performed 2 weeks after treatment initiation seems to be more reliable,” said Dr. Okarska-Napierala, a pediatrician at the Medical University of Warsaw Children’s Hospital.

Broad agreement exists that imaging is warranted in all children with a first urinary tract infection (UTI), because this infection can be the first signal of a structural abnormality of the kidneys or urinary tract. Abdominal ultrasound is the first-choice imaging modality in this setting because it is noninvasive, widely available, and inexpensive. But there remains controversy – and guidelines differ – regarding when to perform the ultrasound in children with UTI who respond well to therapy. This was the impetus for Dr. Okarska-Napierala and her coinvestigators to launch a prospective, single-center study examining the issue.

“The theory beneath it is the possibility that diffuse inflammation affects the ultrasound picture of the kidneys and urinary tract and may give us false-positive results, so we shouldn’t base our decisions on those results,” she explained.

This theory has been provisionally confirmed by the preliminary results of the study, which is continuing to enroll patients.

To date, the study includes 48 children, mean age 10.4 months, hospitalized for their first UTI. Participation was restricted to patients with no known congenital abnormalities of the kidneys or urinary tract and who were not on antibiotics at enrollment. Of the 48 children, 44 had an Escherichia coli infection. The predominant treatment was a second-generation cephalosporin for a median of 10 days.

On day 1 of treatment all patients underwent an ultrasound exam evaluating kidney size, anterior-posterior renal pelvis diameter, and the urinary tract based upon a grading system for urinary tract dilation developed by multidisciplinary consensus (J Pediatr Urol. 2014 Dec;10[6]:982-98). The ultrasound exam was repeated 2 weeks later, and again 2 weeks after that.

The most striking findings were a significantly increased kidney size and more prevalent urinary tract dilation on the day 1 ultrasound exam than on repeat ultrasound 2 weeks later. The average length of the left and right kidneys was 67.0 and 64.5 mm, respectively, on day 1, dropping off to 64.3 and 62.0 mm at 2 weeks, with a smaller and statistically nonsignificant further drop-off to 61.9 and 60.0 mm on the week 4 ultrasound.

“We saw a strong correlation between initial kidney size and CRP [C-reactive protein] value: The higher the CRP you have initially, the bigger the kidneys. It’s an interesting finding, but not so very practical. The only practical conclusion is that if we perform ultrasound at this stage and the child has big kidneys, it doesn’t mean anything. We have to check it again later,” she said.

Also, the number of renal units with urinary tract dilation went from 29 on day 1 ultrasound to 20 at 2 weeks and 19 at 4 weeks. Of the 48 children, 28 had urinary tract dilation on day 1, compared with 18 at 2 weeks and 16 at 4 weeks.

“If we look at this practically, if we base our decision on the day 1 ultrasound we would qualify half of all children for voiding cystourethrography, which is harmful, but if we wait 2 weeks to do the ultrasound we would reduce this number by six children. So I think we can call this a clinically significant difference,” she continued.

Of the 48 children, 11 have undergone voiding cystourethrography, revealing 2 mild cases of vesicoureteral reflux, which is the most common congenital abnormality of the urinary tract.

“I would like to emphasize that there is no real benefit in performing an ultrasound exam in children in this acute phase of infection. And there is harm in that we have to repeat the exam later, the parents are worried, the doctor is worried,” Dr. Okarska-Napierala concluded.

She reported having no relevant financial conflicts, and the study was conducted free of commercial support.

ORLANDO – Adopting a 28-point enhanced recovery protocol for bariatric surgery significantly reduced length of stay without significant effects on complications or readmissions, according to interim results of a large, nationwide surgical quality initiative.

Thirty-six centers participated in this pilot initiative, making it one of the largest national projects focused on enhanced recovery to date, according to Stacy A. Brethauer, MD, FACS, cochair of the Quality and Data Committee of the Metabolic and Bariatric Surgery Accreditation Quality Improvement Program (MBSAQIP).

The initiative, known as Employing New Enhanced Recovery Goals for Bariatric Surgery (ENERGY), was developed in light of “huge gaps in literature and knowledge” about what best practices of enhanced recovery should look like for bariatric surgery, Dr. Brethauer said in a podium presentation at the American College of Surgeons Quality and Safety Conference.

“Bariatric surgery is very pathway driven, but the pathway can be very cumbersome and very antiquated if you don’t keep it up to date and evidence based,” said Dr. Brethauer, associate professor of surgery at the Cleveland Clinic.

Invitations to join in the ENERGY pilot were targeted to the 80 or so MBSAQIP-accredited centers in the top decile of programs for length of stay. “That’s the needle that we want to move,” Dr. Brethauer said.

ENERGY includes interventions in the preoperative, perioperative, and postoperative setting for each patient who undergoes a primary band, lap sleeve, or lap bypass procedure.

The 36 participating centers were asked to document 28 discrete process measures, starting with “did the patient stop smoking before surgery?” and ending with “did the patient have a follow-up clinic appointment scheduled?” Each one was entered by a trained clinical reviewer. The program included monthly audits for each participating center.

Data collection started on July 1, 2017, and continued to June 30, 2018, following a 6-month run-up period to allow centers to incorporate the measures.

The interim analysis presented included 4,700 patients who underwent procedures in the first 6 months of the data collection period. Nearly 60% (2,790 patients) had a laparoscopic sleeve gastrectomy, while about 40% (1,896 patients) underwent laparoscopic gastric bypass, and 0.1% (6 patients) had a band procedure.

Average length of stay was 1.76 days in the first 6 months of the pilot, down from 2.24 days in 2016 for those same participating centers (P less than .001), Dr. Brethauer reported.

Similarly, the rate of extended length of stay was 4.4% in the first 6 months of the pilot, down from 8.2% in 2016. Extended length of stay decreased with increasing adherence to the protocol, Dr. Brethauer and his colleagues found in their analysis.

Those length-of-stay reductions were accomplished with no increase in bleeding rates, all-cause reoperation rates, or readmissions. “We’re not doing this at the expense of other complications,” Dr. Brethauer said in a comment on the results.

Adherence to the 28 ENERGY measures increased from 26% in the first month of the pilot to 80.2% in March 2017, the latest month included in the interim analysis.

Opioid-sparing pain management strategies are incorporated into ENERGY. Over the first six months of the pilot, the average proportion of patients receiving no opioids postoperatively was 26.8%.

The ultimate goal of ENERGY is a large-scale rollout of enhanced recovery strategies, according to Dr. Brethauer.

ENERGY is the second national quality improvement project of the MBSAQIP. In the first, known as Decreasing Readmissions through Opportunities Provided (DROP), 128 U.S. hospitals implemented a set of standard processes organized into preoperative, inpatient, and postoperative care bundles. Results of a yearlong study of the DROP intervention demonstrated a significant reduction in 30-day all-cause hospital readmissions following sleeve gastrectomy.

ORLANDO – Adopting a 28-point enhanced recovery protocol for bariatric surgery significantly reduced length of stay without significant effects on complications or readmissions, according to interim results of a large, nationwide surgical quality initiative.

Thirty-six centers participated in this pilot initiative, making it one of the largest national projects focused on enhanced recovery to date, according to Stacy A. Brethauer, MD, FACS, cochair of the Quality and Data Committee of the Metabolic and Bariatric Surgery Accreditation Quality Improvement Program (MBSAQIP).

The initiative, known as Employing New Enhanced Recovery Goals for Bariatric Surgery (ENERGY), was developed in light of “huge gaps in literature and knowledge” about what best practices of enhanced recovery should look like for bariatric surgery, Dr. Brethauer said in a podium presentation at the American College of Surgeons Quality and Safety Conference.

“Bariatric surgery is very pathway driven, but the pathway can be very cumbersome and very antiquated if you don’t keep it up to date and evidence based,” said Dr. Brethauer, associate professor of surgery at the Cleveland Clinic.

Invitations to join in the ENERGY pilot were targeted to the 80 or so MBSAQIP-accredited centers in the top decile of programs for length of stay. “That’s the needle that we want to move,” Dr. Brethauer said.

ENERGY includes interventions in the preoperative, perioperative, and postoperative setting for each patient who undergoes a primary band, lap sleeve, or lap bypass procedure.

The 36 participating centers were asked to document 28 discrete process measures, starting with “did the patient stop smoking before surgery?” and ending with “did the patient have a follow-up clinic appointment scheduled?” Each one was entered by a trained clinical reviewer. The program included monthly audits for each participating center.

Data collection started on July 1, 2017, and continued to June 30, 2018, following a 6-month run-up period to allow centers to incorporate the measures.

The interim analysis presented included 4,700 patients who underwent procedures in the first 6 months of the data collection period. Nearly 60% (2,790 patients) had a laparoscopic sleeve gastrectomy, while about 40% (1,896 patients) underwent laparoscopic gastric bypass, and 0.1% (6 patients) had a band procedure.

Average length of stay was 1.76 days in the first 6 months of the pilot, down from 2.24 days in 2016 for those same participating centers (P less than .001), Dr. Brethauer reported.

Similarly, the rate of extended length of stay was 4.4% in the first 6 months of the pilot, down from 8.2% in 2016. Extended length of stay decreased with increasing adherence to the protocol, Dr. Brethauer and his colleagues found in their analysis.

Those length-of-stay reductions were accomplished with no increase in bleeding rates, all-cause reoperation rates, or readmissions. “We’re not doing this at the expense of other complications,” Dr. Brethauer said in a comment on the results.

Adherence to the 28 ENERGY measures increased from 26% in the first month of the pilot to 80.2% in March 2017, the latest month included in the interim analysis.

Opioid-sparing pain management strategies are incorporated into ENERGY. Over the first six months of the pilot, the average proportion of patients receiving no opioids postoperatively was 26.8%.

The ultimate goal of ENERGY is a large-scale rollout of enhanced recovery strategies, according to Dr. Brethauer.

ENERGY is the second national quality improvement project of the MBSAQIP. In the first, known as Decreasing Readmissions through Opportunities Provided (DROP), 128 U.S. hospitals implemented a set of standard processes organized into preoperative, inpatient, and postoperative care bundles.

NEW ORLEANS – Physicians committed to fighting the national opioid epidemic really need to take the 8-hour training course on addiction treatment required to obtain a Drug Enforcement Administration ‘X’ number, because it will enable them to prescribe buprenorphine, a drug with unique advantages for many affected patients, Ellie Grossman, MD, asserted at the annual meeting of the American College of Physicians.

Bruce Jancin/MDedge News

Buprenorphine (Subutex) is one of the three medications approved for treatment of opioid use disorder (OUD), along with methadone and naltrexone (Revia). And for certain patients, it’s clearly the best choice, according to Dr. Grossman, a general internist at Harvard Medical School, Boston, and the primary care lead for behavioral health integration at the Cambridge (Mass.) Health Alliance.

The DEA X number certification process, which entails obtaining a waiver through SAMHSA – the Substance Abuse and Mental Health Services Administration – is bureaucratic. It’s unpopular with many physicians. But it’s well worth 8 hours of an internist’s time to get the waiver and gain the ability to prescribe buprenorphine.

“The requirement is admittedly clunky, and many people have strong feelings about whether this is a regulation that should exist,” according to Dr. Grossman. “I myself didn’t need to have special training to prescribe methadone, a full opioid agonist that my patients could easily die from. But I did have to undergo an 8-hour training to prescribe buprenorphine, and it’s much harder to die from that drug.”

She addressed which of the three medications for OUD is the best fit in a given patient, the appropriate treatment duration, and the role of adjunctive counseling, which – spoiler alert – has been cast into question by the results of a major government-funded randomized trial.

Dr. Grossman’s overriding message: “You are saving lives by getting people on medication.”

Indeed, studies have shown that patients with OUD who receive no treatment have a sixfold increase in the standardized mortality ratio, compared with the general population. Contrast that with the less than 2-fold increased risk with medication-assisted treatment and roughly a 2.5-fold increased risk when medication is given short term to cover withdrawal and then tapered and discontinued.

Other documented benefits of long-term medication-assisted treatment of patients with OUD as described in a 2014 Cochrane review include reductions in injection drug use, crime days, HIV-related risk behaviors and seroconversion, and improved health and social functioning.

Of note, those well-documented benefits apply only to methadone, a full opioid agonist, and buprenorphine, a partial agonist, because those two drugs have been around long enough to generate long-term outcome data. Naltrexone, which has a completely different mechanism of action – it’s a full opioid antagonist – has not as of yet.
 

Individualizing medical therapy for OUD

Physicians can’t write a prescription for methadone. The drug must be administered at a certified opioid treatment program, or OTP, otherwise known as a methadone clinic. Those clinics are highly regulated at both the federal and state levels, with lots of minutia involved. Patient counseling and drug screening are required.

In contrast, a physician with a DEA X number can write a prescription for buprenorphine and have a patient fill it at a pharmacy. There is inherently less structure surrounding buprenorphine therapy than that of methadone, Dr. Grossman noted. There are no hard and fast rules about how often a physician has to see the patient or do drug screens or counseling. Buprenorphine is available as once-daily oral sublingual therapy and, more recently, in long-acting injectable and implantable formulations, although Dr. Grossman believes the jury is still out about how these nonoral agents are best utilized.

“I’m often asked, ‘Which is better, methadone or buprenorphine?’ Really, the answer is they’re both pretty darn good,” according to Dr. Grossman.

The Cochrane review concluded that, in the studies that have used real-world dosing – that is, higher doses than in the initial studies – high-dose buprenorphine and high-dose methadone have similar rates of retention in treatment.

“What I tell patients is that a lot hinges on the structure of the treatment delivery system,” Dr. Grossman said. “If it’s methadone, they’re going to the OTP every day. Some people need more structure; they need a set of eyes on them every day. Or if they are at high risk for medication diversion – for example, someone else in their household might want to steal their medications – going to a methadone program gets around that. Also, when somebody has been on methadone in the past and did well on it and wants to go on it again, I’m likely to say, ‘That sounds like a good fit.’”

Buprenorphine is a good option for patients who don’t require close, structured supervision. It has fewer drug interactions than does methadone and is less prone to cause QTc prolongation. Also, it’s a more realistic option for patients who live so far from an OTP that daily attendance is impractical. And ob.gyns increasingly favor buprenorphine, because the problem of neonatal abstinence syndrome is less severe than when mothers are on methadone.

As for extended-release naltrexone (Vivitrol), the pivotal double-blind Russian trial that won FDA approval for treatment of OUD showed a dramatic improvement in opioid-free weeks (Lancet. 2011 Apr 30;377[9776]:1506-13).

More recently, the 24-week, multicenter, open-label X:BOT trial randomized 570 U.S. patients with OUD to once-monthly extended-release naltrexone or daily sublingual buprenorphine-naloxone (Suboxone). The dropout rate was higher in the extended-release naltrexone arm because patients had to be opioid free for 2 weeks before starting on the opioid antagonist. As a practical matter, that can be difficult to achieve unless a patient has just been released from jail or prison. But the per-protocol relapse rates were similar (Lancet. 2018 Jan 27;391[10118]:309-18).

“Many people interpret this study as saying, with the right patient who can get into an opioid-free state or, if you inherit an opioid-free state, the choice between extended-release naltrexone and buprenorphine-naloxone may be a bit of a wash in terms of clinical effectiveness, as best we can detect,” Dr. Grossman explained. “That said, they’re very different experiences: One is a shot in your butt once a month, the other is something you put in your mouth once a day. Patients typically have a strong point of view regarding what they’re up for.”

Extended-release naltrexone doesn’t require a DEA waiver or attendance at an OTP. But it costs roughly $800 per injection, although many insurers do cover it after additional paperwork is completed. While Dr. Grossman does use extended-release naltrexone in her own practice, it comes with some baggage. The drug comes in a powder, which is mixed with a diluent in the office, creating a thick, frothy substance that’s slow to inject. It has to be kept refrigerated, then warmed up in time for the patient visit.

“If you live somewhere where there’s no OTP and you don’t have a DEA X number, and you have a patient with OUD who’s interested in extended-release naltrexone, it’s not crazy to think about,” she noted.
 

Duration of medical therapy

Study after study demonstrates that, when treatment stops, the risk of relapse goes up.

“We as health care providers are used to the mentality of chronic diseases, like diabetes, where you’re probably on medicine for the rest of your life,” Dr. Grossman said. “OUD is another chronic disease where you might have a patient on medication for the rest of their life, although you may not want to drum that into their head right up front. It’s kind of scary. I don’t usually talk that way with my diabetic patients when I give them their diagnosis. So, I don’t push it.

“But the reality is, to give them the best chance of health, they should be on medication for a good long time,” she added. “And that’s true for all of the OUD medications.”
 

The role of counseling

The best evidence of the utility of adjunctive counseling in the treatment of OUD comes from the landmark Prescription Opioid Addiction Treatment Study (POATS), a 653-patient multicenter trial conducted by the National Drug Abuse Treatment Network and funded by the National Institute on Drug Abuse. Participants were randomized to standard medical management including medication and a meeting with a physician every 1-2 weeks, or to standard therapy plus individual counseling with a trained substance use counselor.

To the surprise of many, given that SAMHSA guidance strongly recommends counseling and other forms of behavioral therapy, there was no difference in outcomes between the two groups (Drug Alcohol Depend. 2015 May 1;150:112-9).

Subsequent parsing of the POATS data showed that the subgroup of people who were using heroin rather than prescription pills and who actually attended at least 60% of their counseling sessions did better than if they were randomized to no counseling.

“There’s still room for quibbling about the study, but many people would say, ‘You know, it’s not a slam dunk that everybody needs counseling,’ ” the internist commented.

“So, how do we pick the right treatment for our patients with OUD? It’s what feels right for them,” Dr. Grossman cautioned. “This gets back to what we do every day in managing chronic diseases: We nudge, we encourage, we use our motivational interviewing skills to help people figure out how they can change their lives and get healthier. There’s a long list of things going on in our patients’ lives that are going to help guide that decision.

“The message here: Medication is better than no medication, but it’s not a slam dunk which medication or how,” she concluded.

But the per-protocol relapse rates were similar (Lancet. 2018 Jan 27;391[10118]:309-18).

“Many people interpret this study as saying, with the right patient who can get into an opioid-free state or, if you inherit an opioid-free state, the choice between extended-release naltrexone and buprenorphine-naloxone may be a bit of a wash in terms of clinical effectiveness, as best we can detect,” Dr. Grossman explained. “That said, they’re very different experiences: One is a shot in your butt once a month, the other is something you put in your mouth once a day. Patients typically have a strong point of view regarding what they’re up for.”

Extended-release naltrexone doesn’t require a DEA waiver or attendance at an OTP. But it costs roughly $800 per injection, although many insurers do cover it after additional paperwork is completed. While Dr. Grossman does use extended-release naltrexone in her own practice, it comes with some baggage. The drug comes in a powder, which is mixed with a diluent in the office, creating a thick, frothy substance that’s slow to inject. It has to be kept refrigerated, then warmed up in time for the patient visit.

“If you live somewhere where there’s no OTP and you don’t have a DEA X number, and you have a patient with OUD who’s interested in extended-release naltrexone, it’s not crazy to think about,” she noted.
 

Duration of medical therapy

Study after study demonstrates that, when treatment stops, the risk of relapse goes up.

“We as health care providers are used to the mentality of chronic diseases, like diabetes, where you’re probably on medicine for the rest of your life,” Dr. Grossman said. “OUD is another chronic disease where you might have a patient on medication for the rest of their life, although you may not want to drum that into their head right up front. It’s kind of scary. I don’t usually talk that way with my diabetic patients when I give them their diagnosis. So, I don’t push it.

“But the reality is, to give them the best chance of health, they should be on medication for a good long time,” she added. “And that’s true for all of the OUD medications.”
 

The role of counseling

The best evidence of the utility of adjunctive counseling in the treatment of OUD comes from the landmark Prescription Opioid Addiction Treatment Study (POATS), a 653-patient multicenter trial conducted by the National Drug Abuse Treatment Network and funded by the National Institute on Drug Abuse. Participants were randomized to standard medical management including medication and a meeting with a physician every 1-2 weeks, or to standard therapy plus individual counseling with a trained substance use counselor.

To the surprise of many, given that SAMHSA guidance strongly recommends counseling and other forms of behavioral therapy, there was no difference in outcomes between the two groups (Drug Alcohol Depend. 2015 May 1;150:112-9).

Subsequent parsing of the POATS data showed that the subgroup of people who were using heroin rather than prescription pills and who actually attended at least 60% of their counseling sessions did better than if they were randomized to no counseling.

“There’s still room for quibbling about the study, but many people would say, ‘You know, it’s not a slam dunk that everybody needs counseling,’ ” the internist commented.

“So, how do we pick the right treatment for our patients with OUD? It’s what feels right for them,” Dr. Grossman cautioned. “This gets back to what we do every day in managing chronic diseases: We nudge, we encourage, we use our motivational interviewing skills to help people figure out how they can change their lives and get healthier. There’s a long list of things going on in our patients’ lives that are going to help guide that decision.

“The message here: Medication is better than no medication, but it’s not a slam dunk which medication or how,” she concluded.

A bundle of blood cultures, broad-spectrum antibiotics, and intravenous fluid replacement reduces risk of in-hospital mortality among children with sepsis if all three forms of management are initiated within an hour, according to a cohort study published in JAMA.

invisioner/Thinkstock

Although published guidelines already recommend prompt initiation of these three elements of care, a mandate created in New York in 2013 called for these interventions to be initiated in children within 1 hour of sepsis recognition. The newly published cohort study shows a mortality benefit when this is done.

In the study, which evaluated the impact of the bundle as well as each of the components in 1,179 pediatric patients with sepsis treated at 54 hospitals, the risk-adjusted odds ratio of in-hospital mortality was 0.59 (P = .02) among patients receiving the mandated protocol, compared with those who did not.

When provided within 1 hour, none of the individual components of the bundles were associated with a significant reduction of risk-adjusted, in-hospital mortality by themselves. However, there were trends for benefit with blood cultures (OR, 0.73; P = .1) and broad-spectrum antibiotics (OR, 0.78; P = .18). There was no trend for administration of intravenous fluids (OR, 0.88; P = .56), for which the mandate specified 20 mL/kg.

Although 46.5% of patients received intravenous fluids, 62.8% received broad-spectrum antibiotics, and blood cultures were obtained in 67.7% of the children within 1 hour, only 24.9% were managed with the entire sepsis bundle. Across hospitals, the proportion of children completing the bundle ranged from 7.3% to 46.1%.

Bundle completion was more common in hospitals already treating a relatively high volume of pediatric patients and in those with pediatric specialty services, but the study authors noted that this was not a linear relationship. Rather, they called this association “hypothesis generating” and speculated that other factors might also be important.

The children in this cohort ranged in age from under 1 month to 17 years. Slightly more than half were aged 6 years or older and nearly one-third were older than 12 years. Nearly 45% had no comorbidities. Slightly more than one-third had a malignancy or were immunosuppressed.

None of the study authors reported any relevant financial relationships with industry.

NEW ORLEANS – Comanagement of orthopedic inpatients by an internist or hospitalist can improve outcomes in myriad ways, Mary Anderson Wallace, MD, said at the annual meeting of the American College of Physicians.

She focused on patients undergoing total hip or knee arthroplasty (THA/TKA). In 2014, there were 400,000 of them under Medicare alone, accounting for $7 billion in hospitalization costs and nearly as much again in the cost of related postdischarge care.

Optimizing perioperative pain management pathways

As of 2015, orthopedists ranked as the third highest prescribers of opioids. Impressively, a retrospective cohort study of 641,941 opioid-naive, privately insured patients undergoing 1 of 11 types of surgery demonstrated that TKA was associated with a 5.1-fold increased risk for subsequent chronic opioid use in the first year after surgery, compared with 18 million opioid-naive nonsurgical controls. Indeed, TKA was the highest-risk of the 11 surgical procedures examined (JAMA Intern Med. 2016 Sep 1;176[9]:1286-93).

Another study that points to a need to develop best practices for opioid prescribing in orthopedic surgery – and other types of surgery as well – was a systematic review of six studies of patients who received prescription opioid analgesics in conjunction with seven types of surgery.

Opioid oversupply was identified as a clear problem: 67%-92% of patients in the six studies reported unused opioids. Up to 71% of opioid tablets went unused, mainly because patients felt they’d achieved adequate pain control and didn’t need them. Rates of safe disposal of unused opioids were in the single digits, suggesting that overprescribing provides a large potential reservoir of opioids that can be diverted to nonmedical use (JAMA Surg. 2017 Nov 1;152[11]:1066-71).

Moreover, a recent retrospective study of more than 1 million opioid-naive patients undergoing surgery showed that 56% of them received postoperative opioids. And each additional week of use was associated with a 44% increase in the relative risk of the composite endpoint of opioid dependence, abuse, or overdose. Duration of opioid use was a stronger predictor of this adverse outcome than was dosage (BMJ. 2018 Jan 17;360:j5790).

Other studies have shown that multimodal analgesia is utilized in only 25%-50% of surgical patients, even though it is considered the standard of care. Only 20% of patients undergoing THA/TKA receive peripheral nerve and neuraxial blocks. So, there is an opportunity for optimization of perioperative pain management pathways in orthopedic surgery patients, including avoidance of unnecessary p.r.n. prescribing, to favorably impact the national opioid epidemic, Dr. Wallace observed.

A surprise benefit of multimodal pain management that includes acetaminophen and a nonsteroidal anti-inflammatory agent is that it markedly reduces the incidence of postoperative fevers after total joint arthroplasty, compared with opioid-based pain management.

That was demonstrated in a retrospective study of 2,417 THA/TKAs in which multimodal pain management was used, and 1,484 procedures that relied on opioid-based pain relief. All of the operations were performed by the same three orthopedic surgeons. Only 5% of patients in the multimodal pain management group developed a fever greater than 38.5 degrees Celsius during the first 5 postoperative days, compared with 25% of those in the opioid-based analgesia group.

Moreover, an infectious disease workup was ordered in 2% of the multimodal analgesia group, versus 10% in the opioid-based pain management cohort, with no difference in the positive workup rates between the two groups (Clin Orthop Relat Res. 2014 May;472[5]:1489-95).

“It’s interesting that multimodal pain management has the side effect of putting you in a better position to practice high-value care, with less fever and fewer infectious disease workups,” Dr. Wallace said.
 

Perioperative management of DMARDs

Recent joint guidelines from the American College of Rheumatology and American Association of Hip and Knee Surgeons specifically address this issue in patients undergoing elective joint replacement (Arthritis Rheumatol. 2017 Aug;69[8]:1538-51).

“The quality of evidence isn’t high, but at least it’s a starting point,” Dr. Wallace said.

Patients with rheumatoid arthritis, systemic lupus erythematosus, spondyloarthropathies, and other rheumatic diseases who are on methotrexate or other nonbiologic DMARDs should be maintained on their current dose, according to the guidelines.

In contrast, all biologic agents should be withheld prior to surgery, which should be scheduled to coincide with the end of the dosing cycle for that specific biologic. The biologic agent should be resumed only once adequate wound healing has occurred, typically about 14 days post-THA/TKA.

Patients on daily glucocorticoids should continue on their current dose; supraphysiologic stress dosing is to be avoided.
 

Low-dose aspirin for VTE prophylaxis

“It seems like nothing has been such an enduring controversy in the comanagement literature as the question of whether aspirin is an effective prophylactic agent for prevention of DVT post THA/TKA,” according to Dr. Wallace.

She noted that in the space of just 4 years between the eighth and ninth editions of the American College of Chest Physician guidelines, that organization underwent a 180-degree reversal on the issue – whipsawing from a grade 1A recommendation against aspirin in 2008 to a 1B recommendation for it in 2012.

The literature is increasingly supportive of the use of aspirin for venous thromboembolism (VTE) prophylaxis in low-risk THA/TKA patients. Separate guidelines from the American Academy of Orthopaedic Surgeons (AAOS) and the Surgical Care Improvement Project, as well as the chest physicians, support the practice.

The hitch is that there is as yet no single validated risk-stratification protocol. AAOS recommends 325 mg of aspirin twice daily for 6 weeks. But a prospective crossover study of more than 4,600 total joint arthroplasty patients conducted by investigators at Thomas Jefferson University in Philadelphia showed that 81 mg BID for 4 weeks was just as effective as was 325 mg b.i.d., albeit with an incidence of GI bleeding that to their surprise wasn’t significantly lower (J Bone Joint Surg Am. 2017 Jan 18;99[2]:91-8).

Dr. Wallace anticipates definitive answers on VTE prophylaxis to come from the ongoing Patient-Centered Outcomes Research Institute-supported PEPPER (Comparative Effectiveness of Pulmonary Embolism Prevention After Hip and Knee Replacement) trial. In that study, roughly 25,000 patients undergoing THA/TKA are being randomized to prophylactic aspirin at 81 mg b.i.d., warfarin at an International Normalized Ratio of 2.0, or rivaroxaban (Xarelto). Endpoints include mortality, VTE, and bleeding. Results are expected in 2021.
 

Preoperative prediction of postop delirium

Unrecognized preoperative cognitive impairment in older patients without dementia who are undergoing THA/TKA is a common and powerful risk factor for postop delirium and other complications, as demonstrated recently by investigators at Harvard University and affiliated hospitals.

They had 211 patients aged 65 or older, none with known dementia, take the Mini-Cog screening test prior to their surgery. Fully 24% had probable cognitive impairment as reflected in a score of 2 or less out of a possible 5 points on this simple test, which consists of a three-word recall and clock drawing.

“I was very surprised at this high rate. These are patients who are at risk for delirium in the hospital when you’re taking care of them,” Dr. Wallace observed.

In the Harvard study, the incidence of postop delirium was 21% in patients with a Mini-Cog score of 2 or less, compared with 7% who scored 3-5, for an odds ratio of 4.5 in an age-adjusted multivariate analysis. Moreover, 67% of the low scorers were discharged somewhere other than home, in contrast to 34% of patients with a preop Mini-Cog score of 3-5, for an adjusted 3.9-fold increased risk. The group with a Mini-Cog score of 2 or less also had a significantly longer hospital length of stay (Anesthesiology. 2017 Nov;127[5]:765-74).

Perioperative gabapentin is often added to the medication regimen of older surgical patients to reduce postop delirium. The latest evidence indicates that doesn’t work, as demonstrated in a recent 697-patient randomized trial. The incidence of delirium during the first 3 days post surgery as measured by the Confusion Assessment Method was 22.4% in patients randomized to 900 mg of gabapentin per day, and 20.8% with placebo. Nearly 200 participants had THA or TKA, and in that subgroup, there was an even stronger – albeit still not statistically significant – trend for a higher delirium rate with gabapentin than with placebo (Anesthesiology. 2017 Oct.127[4]:633-44).

“Think twice about adding gabapentin to the pain regimen for THA/TKA/spine patients for the purpose of preventing postop delirium,” she advised.
 

When is postop fever a concern?

Up to half of patients develop fever early after THA/TKA. In most cases, this is a self-limited ancillary effect of cytokine release, with the temperature peaking on postop day 1-2.

Three strong predictors of a positive infectious disease workup are fever after postop day 3, with an associated 23.3-fold increased risk; multiple days of fever, with an odds ratio of 8.6; and a maximum temperature greater than 39.0 degrees Celsius, with a 2.4-fold increased risk. In this 7-year-old study, the cost of infectious disease workup per change in patient management was a hefty $8,209 (J Arthroplasty. 2010 Sep;25[6 Suppl]:43-8).

A retrospective study of nearly 125,000 THA/TKA patients in the American College of Surgeons National Surgical Quality Improvement Program database has important implications for clinical surveillance for postop adverse events. Stroke occurred early, on median postop day 1. The median time of acute MI and pulmonary embolism was postop day 3, and pneumonia day 4.

The key take-home message was that the median time to DVT was postop day 6, by which point most patients had been discharged. Thus, 60% of postoperative DVTs occurred after discharge. And the time to diagnosis of DVT differed markedly by surgical procedure: The median day of diagnosis was day 5 in TKA patients, compared with day 13 for THA patients. Sixty-eight percent of urinary tract infections occurred post discharge. Sepsis occurred on median day 10 post surgery, surgical site infections on day 17 (Clin Orthop Relat Res. 2017 Dec;475[12]:2952-9).

In light of ever-shortening hospital lengths of stay, Dr. Wallace noted, the findings underscore the importance of comprehensive predischarge patient counseling.
 

Optimal time window for hip fracture surgery

AAOS guidelines recommend that hip fracture surgery should take place within 48 hours, assuming medical comorbidities are stabilized, because complication rates go up with longer wait times.

But that is controversial. A University of Toronto retrospective cohort study of 42,430 adults with hip fracture treated at 72 Canadian hospitals during 2009-2014 found that the inflection point was 24 hours. Among 13,731 patients whose elapsed time from hospital arrival to surgery was 24 hours or less, 30-day mortality was 5.8%, significantly less than the 6.5% rate in an equal number of propensity score–matched patients with a longer wait time.

The 90- and 365-day mortality rates in the patients who received surgery within 24 hours were 10.7% and 19.3%, both significantly lower than the 12.0% and 21.6% figures in patients with longer wait times.

For the 30-day composite outcome of death, myocardial infarction, pulmonary embolism, DVT, or pneumonia, the rates were 10.1% and 12.2% – again, statistically significant and clinically meaningful. The 90- and 365-day composite outcomes followed suit (JAMA. 2017 Nov 28;318[20]:1994-2003).

But the Canadian study won’t be the final word. The ongoing international multicenter HIP ATTACK (Hip Fracture Accelerated Surgical Treatment and Care Track) trial is comparing outcomes in 3,000 patients randomized to hip fracture surgery within 6 hours versus 24 hours. Endpoints include mortality, myocardial infarction, pulmonary embolism, pneumonia, stroke, sepsis, and life-threatening and major bleeding.

Dr. Wallace reported having no financial conflicts regarding her presentation.

In this 7-year-old study, the cost of infectious disease workup per change in patient management was a hefty $8,209 (J Arthroplasty. 2010 Sep;25[6 Suppl]:43-8).

A retrospective study of nearly 125,000 THA/TKA patients in the American College of Surgeons National Surgical Quality Improvement Program database has important implications for clinical surveillance for postop adverse events. Stroke occurred early, on median postop day 1. The median time of acute MI and pulmonary embolism was postop day 3, and pneumonia day 4.

The key take-home message was that the median time to DVT was postop day 6, by which point most patients had been discharged. Thus, 60% of postoperative DVTs occurred after discharge. And the time to diagnosis of DVT differed markedly by surgical procedure: The median day of diagnosis was day 5 in TKA patients, compared with day 13 for THA patients. Sixty-eight percent of urinary tract infections occurred post discharge. Sepsis occurred on median day 10 post surgery, surgical site infections on day 17 (Clin Orthop Relat Res. 2017 Dec;475[12]:2952-9).

In light of ever-shortening hospital lengths of stay, Dr. Wallace noted, the findings underscore the importance of comprehensive predischarge patient counseling.
 

Optimal time window for hip fracture surgery

AAOS guidelines recommend that hip fracture surgery should take place within 48 hours, assuming medical comorbidities are stabilized, because complication rates go up with longer wait times.

But that is controversial. A University of Toronto retrospective cohort study of 42,430 adults with hip fracture treated at 72 Canadian hospitals during 2009-2014 found that the inflection point was 24 hours. Among 13,731 patients whose elapsed time from hospital arrival to surgery was 24 hours or less, 30-day mortality was 5.8%, significantly less than the 6.5% rate in an equal number of propensity score–matched patients with a longer wait time.

The 90- and 365-day mortality rates in the patients who received surgery within 24 hours were 10.7% and 19.3%, both significantly lower than the 12.0% and 21.6% figures in patients with longer wait times.

For the 30-day composite outcome of death, myocardial infarction, pulmonary embolism, DVT, or pneumonia, the rates were 10.1% and 12.2% – again, statistically significant and clinically meaningful. The 90- and 365-day composite outcomes followed suit (JAMA. 2017 Nov 28;318[20]:1994-2003).

But the Canadian study won’t be the final word. The ongoing international multicenter HIP ATTACK (Hip Fracture Accelerated Surgical Treatment and Care Track) trial is comparing outcomes in 3,000 patients randomized to hip fracture surgery within 6 hours versus 24 hours. Endpoints include mortality, myocardial infarction, pulmonary embolism, pneumonia, stroke, sepsis, and life-threatening and major bleeding.

Dr. Wallace reported having no financial conflicts regarding her presentation.

NEW ORLEANS – Comanagement of orthopedic inpatients by an internist or hospitalist can improve outcomes in myriad ways, Mary Anderson Wallace, MD, said at the annual meeting of the American College of Physicians.

She focused on patients undergoing total hip or knee arthroplasty (THA/TKA). In 2014, there were 400,000 of them under Medicare alone, accounting for $7 billion in hospitalization costs and nearly as much again in the cost of related postdischarge care.

Optimizing perioperative pain management pathways

As of 2015, orthopedists ranked as the third highest prescribers of opioids. Impressively, a retrospective cohort study of 641,941 opioid-naive, privately insured patients undergoing 1 of 11 types of surgery demonstrated that TKA was associated with a 5.1-fold increased risk for subsequent chronic opioid use in the first year after surgery, compared with 18 million opioid-naive nonsurgical controls. Indeed, TKA was the highest-risk of the 11 surgical procedures examined (JAMA Intern Med. 2016 Sep 1;176[9]:1286-93).

Another study that points to a need to develop best practices for opioid prescribing in orthopedic surgery – and other types of surgery as well – was a systematic review of six studies of patients who received prescription opioid analgesics in conjunction with seven types of surgery.

Opioid oversupply was identified as a clear problem: 67%-92% of patients in the six studies reported unused opioids. Up to 71% of opioid tablets went unused, mainly because patients felt they’d achieved adequate pain control and didn’t need them. Rates of safe disposal of unused opioids were in the single digits, suggesting that overprescribing provides a large potential reservoir of opioids that can be diverted to nonmedical use (JAMA Surg. 2017 Nov 1;152[11]:1066-71).

Moreover, a recent retrospective study of more than 1 million opioid-naive patients undergoing surgery showed that 56% of them received postoperative opioids. And each additional week of use was associated with a 44% increase in the relative risk of the composite endpoint of opioid dependence, abuse, or overdose. Duration of opioid use was a stronger predictor of this adverse outcome than was dosage (BMJ. 2018 Jan 17;360:j5790).

Other studies have shown that multimodal analgesia is utilized in only 25%-50% of surgical patients, even though it is considered the standard of care. Only 20% of patients undergoing THA/TKA receive peripheral nerve and neuraxial blocks. So, there is an opportunity for optimization of perioperative pain management pathways in orthopedic surgery patients, including avoidance of unnecessary p.r.n. prescribing, to favorably impact the national opioid epidemic, Dr. Wallace observed.

A surprise benefit of multimodal pain management that includes acetaminophen and a nonsteroidal anti-inflammatory agent is that it markedly reduces the incidence of postoperative fevers after total joint arthroplasty, compared with opioid-based pain management.

That was demonstrated in a retrospective study of 2,417 THA/TKAs in which multimodal pain management was used, and 1,484 procedures that relied on opioid-based pain relief. All of the operations were performed by the same three orthopedic surgeons. Only 5% of patients in the multimodal pain management group developed a fever greater than 38.5 degrees Celsius during the first 5 postoperative days, compared with 25% of those in the opioid-based analgesia group.

Moreover, an infectious disease workup was ordered in 2% of the multimodal analgesia group, versus 10% in the opioid-based pain management cohort, with no difference in the positive workup rates between the two groups (Clin Orthop Relat Res. 2014 May;472[5]:1489-95).

“It’s interesting that multimodal pain management has the side effect of putting you in a better position to practice high-value care, with less fever and fewer infectious disease workups,” Dr. Wallace said.
 

Perioperative management of DMARDs

Recent joint guidelines from the American College of Rheumatology and American Association of Hip and Knee Surgeons specifically address this issue in patients undergoing elective joint replacement (Arthritis Rheumatol. 2017 Aug;69[8]:1538-51).

“The quality of evidence isn’t high, but at least it’s a starting point,” Dr. Wallace said.

Patients with rheumatoid arthritis, systemic lupus erythematosus, spondyloarthropathies, and other rheumatic diseases who are on methotrexate or other nonbiologic DMARDs should be maintained on their current dose, according to the guidelines.

In contrast, all biologic agents should be withheld prior to surgery, which should be scheduled to coincide with the end of the dosing cycle for that specific biologic. The biologic agent should be resumed only once adequate wound healing has occurred, typically about 14 days post-THA/TKA.

Patients on daily glucocorticoids should continue on their current dose; supraphysiologic stress dosing is to be avoided.
 

Low-dose aspirin for VTE prophylaxis

“It seems like nothing has been such an enduring controversy in the comanagement literature as the question of whether aspirin is an effective prophylactic agent for prevention of DVT post THA/TKA,” according to Dr. Wallace.

She noted that in the space of just 4 years between the eighth and ninth editions of the American College of Chest Physician guidelines, that organization underwent a 180-degree reversal on the issue – whipsawing from a grade 1A recommendation against aspirin in 2008 to a 1B recommendation for it in 2012.

The literature is increasingly supportive of the use of aspirin for venous thromboembolism (VTE) prophylaxis in low-risk THA/TKA patients. Separate guidelines from the American Academy of Orthopaedic Surgeons (AAOS) and the Surgical Care Improvement Project, as well as the chest physicians, support the practice.

The hitch is that there is as yet no single validated risk-stratification protocol. AAOS recommends 325 mg of aspirin twice daily for 6 weeks. But a prospective crossover study of more than 4,600 total joint arthroplasty patients conducted by investigators at Thomas Jefferson University in Philadelphia showed that 81 mg BID for 4 weeks was just as effective as was 325 mg b.i.d., albeit with an incidence of GI bleeding that to their surprise wasn’t significantly lower (J Bone Joint Surg Am. 2017 Jan 18;99[2]:91-8).

Dr. Wallace anticipates definitive answers on VTE prophylaxis to come from the ongoing Patient-Centered Outcomes Research Institute-supported PEPPER (Comparative Effectiveness of Pulmonary Embolism Prevention After Hip and Knee Replacement) trial. In that study, roughly 25,000 patients undergoing THA/TKA are being randomized to prophylactic aspirin at 81 mg b.i.d., warfarin at an International Normalized Ratio of 2.0, or rivaroxaban (Xarelto). Endpoints include mortality, VTE, and bleeding. Results are expected in 2021.
 

Preoperative prediction of postop delirium

Unrecognized preoperative cognitive impairment in older patients without dementia who are undergoing THA/TKA is a common and powerful risk factor for postop delirium and other complications, as demonstrated recently by investigators at Harvard University and affiliated hospitals.

They had 211 patients aged 65 or older, none with known dementia, take the Mini-Cog screening test prior to their surgery. Fully 24% had probable cognitive impairment as reflected in a score of 2 or less out of a possible 5 points on this simple test, which consists of a three-word recall and clock drawing.

“I was very surprised at this high rate. These are patients who are at risk for delirium in the hospital when you’re taking care of them,” Dr. Wallace observed.

In the Harvard study, the incidence of postop delirium was 21% in patients with a Mini-Cog score of 2 or less, compared with 7% who scored 3-5, for an odds ratio of 4.5 in an age-adjusted multivariate analysis. Moreover, 67% of the low scorers were discharged somewhere other than home, in contrast to 34% of patients with a preop Mini-Cog score of 3-5, for an adjusted 3.9-fold increased risk. The group with a Mini-Cog score of 2 or less also had a significantly longer hospital length of stay (Anesthesiology. 2017 Nov;127[5]:765-74).

Perioperative gabapentin is often added to the medication regimen of older surgical patients to reduce postop delirium. The latest evidence indicates that doesn’t work, as demonstrated in a recent 697-patient randomized trial. The incidence of delirium during the first 3 days post surgery as measured by the Confusion Assessment Method was 22.4% in patients randomized to 900 mg of gabapentin per day, and 20.8% with placebo. Nearly 200 participants had THA or TKA, and in that subgroup, there was an even stronger – albeit still not statistically significant – trend for a higher delirium rate with gabapentin than with placebo (Anesthesiology. 2017 Oct.127[4]:633-44).

“Think twice about adding gabapentin to the pain regimen for THA/TKA/spine patients for the purpose of preventing postop delirium,” she advised.
 

When is postop fever a concern?

Up to half of patients develop fever early after THA/TKA. In most cases, this is a self-limited ancillary effect of cytokine release, with the temperature peaking on postop day 1-2.

Three strong predictors of a positive infectious disease workup are fever after postop day 3, with an associated 23.3-fold increased risk; multiple days of fever, with an odds ratio of 8.6; and a maximum temperature greater than 39.0 degrees Celsius, with a 2.4-fold increased risk.
