Patients Who Undergo Weight-Loss Operations at Accredited Bariatric Surgical Centers Have Fewer Postoperative Complications

Findings reveal that some patients are frustrated and discontinued medication because they were not reaching their individualized A1C target quick enough

Chicago, Illinois—Patients who have weight-loss operations at nonaccredited bariatric surgical facilities in the United States are up to 1.4 times likelier to experience serious complications and more than twice as likely to die after the operation compared with patients who undergo these procedures at accredited bariatric surgical centers, researchers conclude. These results from a systematic review of published medical studies that included more than 1 million patients appear online as an “article in press” on the Journal of the American College of Surgeons website in advance of print publication.

These findings have potential implications for the increasing number of people who choose surgical treatment for obesity—widely considered the most effective long-term weight-loss therapy.[1] An estimated 179,000 people underwent gastric bypass, gastric banding, and other bariatric operations in 2013 versus 158,000 two years earlier, according to the American Society for Metabolic and Bariatric Surgery (ASMBS).[2]

The researchers called their new analysis the first comprehensive review of the best available evidence comparing bariatric surgical results in accredited versus nonaccredited U.S. centers.

“A preponderance of scientific evidence demonstrates that bariatric surgery becomes safer with accreditation of the surgical center,” said principal investigator John Morton, MD, MPH, FACS, FASMBS, chief of bariatric and minimally invasive surgery, Stanford (Calif.) University School of Medicine. “Accreditation makes a big difference.”

Despite the published evidence, the Centers for Medicare & Medicaid Services (CMS) no longer requires Medicare patients to undergo covered bariatric surgical procedures at an accredited bariatric center. The agency’s decision in 2013 reversed a 2006 CMS policy to limit coverage for bariatric operations to only those performed at accredited bariatric surgical facilities.

Facility accreditation has been available in the bariatric surgery field for more than a decade. The American College of Surgeons (ACS) and the ASMBS merged their similar accreditation programs in 2012 to create the unified Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP). Currently more than 700 centers in the country now hold this accreditation, according to the MBSAQIP. This credential designates that a surgical facility has met rigorous standards for high-quality surgical care.

According to the ASMBS, most bariatric surgical procedures performed in recent years were minimally invasive laparoscopic procedures.[2]

Dr. Morton, MBSAQIP Co-Chair and immediate past president of the ASMBS, said his prior research found that laparoscopic bariatric operations have fewer postoperative complications than do traditional “open” surgical procedures.[3]

“Even though we use little incisions, it’s still a big operation,” he said. “Accreditation indicates that a bariatric surgical center has the resources and experience in place to take care of any complications that may potentially occur.”

In their review article, Dr. Morton and first author Dan Azagury, MD, also from Stanford, included 13 studies[4] published between 2009 and 2014 and totaling more than 1.5 million patients. Dr. Morton acknowledged that a number of patients might be duplicates because some studies used the same national database, and therefore he could estimate a total in excess of 1 million patients.

Eight of 11 studies that evaluated postoperative complications found that undergoing a bariatric operation in an accredited facility reduced the odds of having a serious complication by 9 to 39 percent (odds ratios of 1.09 to 1.39), the researchers reported.

The difference was reportedly even more pronounced for the risk of death occurring in the hospital or up to 90 days postoperatively. Six of eight studies that reported mortality showed that the odds of dying after a bariatric procedure, while low at an accredited center, was 2.26 to 3.57 times higher at a nonaccredited facility.

Nearly all the studies used risk adjustment, which compensates for different levels of patient risk and which experts believe makes results more accurate.

Only three studies (23 percent) failed to show a significant benefit of accreditation, and those studies had limitations, according to Dr. Morton. For instance, in one study most patients underwent their operations in a bariatric surgical collaborative, whose standards at even nonaccredited centers were very similar to those of accredited centers,[5] he said.

When analyzing studies that reported average hospital charges, Drs. Morton and Azagury found lower costs at accredited centers.

“Accredited bariatric surgical centers provide not only safer care but also less expensive care,” Dr. Morton said.

Patients often choose a bariatric surgical facility by its distance from home, he noted, but added, “It’s worth it for patients to drive a few minutes longer to an accredited center, although the drive typically is short, with more than 700 accredited centers nationwide.”

A systematic review was the best way to study this issue, according to Dr. Morton. He said most insurers today will not cover surgical care at nonaccredited bariatric centers, thus making it difficult to perform a randomized controlled clinical trial, which is considered the gold standard in medical research. Many private insurers, he explained, began to require accreditation after CMS initially required it for reimbursement 10 years ago, before later reversing the policy.

“These results provide important information that can be used to guide future policy decisions. Perhaps CMS should revisit this policy again,” Dr. Morton suggested.

Patients can find an accredited bariatric surgical center on the MBSAQIP website: https://www.facs.org/quality-programs/mbsaqip.

News from the obesity society

New research shows keeping the weight off is a lot more than willpower

SILVER SPRING, Maryland—A front-page article in The New York Times in May spotlighted a National Institutes of Health study in Obesity that studied 14 former contestants of the reality TV show The Biggest Loser who regained an average of 90 pounds—nearly 70% of what they had lost—six years after the show because of complex factors that affected their metabolism and caused their bodies to regain the weight. Researchers explained that a lowered resting metabolic rate (RMR) was partly to blame. RMR is the rate at which calories are burned at rest, which contributes to total daily energy expenditure (TDEE). This study, which was discussed widely on the Internet following The New York Times story, is now published in the August print edition of Obesity, the scientific journal of The Obesity Society, along with a second, new paper also examining metabolic rates after weight loss. In a special mini-series in the journal, leading obesity experts weigh in on the two papers through two additional commentaries and an editorial, all of which explain the phenomenon of metabolic adaptation, or the process where weight loss is accompanied by a decline in energy (caloric) expenditure as weight is lost. These studies were conducted on different populations, but reached the same conclusion: weight regain results from complex biological forces. The common accusation that individuals who don’t keep the weight off just lack willpower is incorrect.

“Obesity is a serious disease that cannot be ‘cured’ with weight loss,” says Donna Ryan, MD, FTOS, Associate Editor in Chief of Obesity and spokesperson for The Obesity Society. “Research is showing that once people lose weight and their metabolism slows, they experience an increase in appetite and a decrease in energy expenditure. These studies demonstrate that keeping the weight off long term requires constant vigilance and lifestyle changes to combat the biologic factors that are fighting to regain the weight.”

In the second paper released July 27, 2016, researchers Michael Rosenbaum, MD, and Rudolph L. Leibel, MD, examined 17 individuals with obesity first at their usual weight, again during maintenance of a 10% reduced weight, and a final time during maintenance of a 20% reduced weight. Their goal was to determine whether the reduction in energy expenditure was directly proportional to the amount of weight lost, if it was proportional up to a certain point, or if it was increasingly—or even exponentially—proportional. They found that all three models were effective.

While these authors found that energy expenditure is explained by a combination of the three models, Fothergill et al’s research on The Biggest Loser contestants seems to fall in line with the proportional model, where the more weight is lost the more the energy expenditure will decrease.

“This study reinforces the complexities of obesity, illustrating that dramatic weight loss, such as that experienced by contestants from The Biggest Loser, may not be the best approach for keeping weight off long term,” continued Dr. Ryan. “Efforts to maintain weight loss should focus on establishing sustainable diet and physical activity routines. While they may not lead to the dramatic weight loss experienced by contestant on The Biggest Loser, they can improve overall health and well-being.”

NEWS FROM THE AMERICAN COLLEGE OF SURGEONS

Non-technical skills matter too: Nation’s doctors, payers and surgical stakeholders recommend teamwork, communication training and standardized processes to improve safety

Each member of the surgical team should be empowered to speak up and take responsibility for patient care

ROSEMONT, Illinois—Patient safety before, during, and after surgery requires an appropriately educated, committed and empowered health care team, according to recommendations being presented at the inaugural National Surgical Patient Safety Summit (NSPSS). The two-day event, which includes more than 100 representatives from medical professional associations, insurers, health care systems, payers and government agencies, is sponsored by the American Academy of Orthopaedic Surgeons (AAOS) and the American College of Surgeons (ACS), with the goals of developing surgical care and surgical education curricula standards, and prioritizing safety research efforts.

Technical and non-technical skills are both important to successfully and safely perform surgery. The surgeon, anesthesiologist, nurses, and all supporting staff must ensure consistent use of surgical safety strategies and tools throughout surgical care, including patient-centered shared-decision making and timely informed consent, standardized surgical site marking procedures, accurate surgical information transfer, integrated electronic medical records, and effective team communication and coordination.

“Surgical safety improves when non-technical strategies, tools and behaviors are combined with proficient surgical skills,” said William Robb, MD, co-chair of NSPSS and past-chair of the AAOS Patient Safety Committee.“Each member of the surgical team needs to know how to effectively communicate and appropriately adapt during an adverse situation. An empowered, well-trained surgical team improves surgeon performance and patient outcomes.”

“As patient safety has always been our highest priority, there is tremendous value in bringing together surgical organizations and other groups concerned about this important issue to collaboratively work on prioritizing surgical patient safety standards,” said David B. Hoyt, MD, FACS, NSPSS co-chair and ACS Executive Director. “This Summit and its resulting recommendations are innovative, and will have a very positive impact on the quality of surgical patient care.”

Workgroups, including surgeons, anesthesiologists and nurses, convened prior to the summit to prepare draft recommendations for all surgical team members, surgical institutions, medical and nursing schools, surgical residency and fellowship programs, and surgical credentialing organizations. The recommendations include the creation and adoption of standardized:

• Surgical safety education programs with assessment of competence for surgeons, residents, medical students, perioperative team members, and surgical institutions on effective communication, resilience, leadership and teamwork.

• Safety training modules (simulation-based) for the entire surgical team—doctors, nurses, anesthesiologists, surgical technicians and physician assistants.

• Training on teamwork, and other essential non-technical skills, beginning during undergraduate medical education, and continuing through surgical residency and postgraduate training, as a requirement of ongoing Maintenance of Certification (MOC).

• “Shared-decision making” practices and procedures to ensure an informed and prepared surgical patient.

• Patient-centered, timely and accurate surgical consent processes.

• Communication tools and procedures to improve the accuracy and efficiency of transferring patient information before, during and following surgical care.

• Surgical site marking and identification policies (with local modifications as appropriate) for all surgical procedures and surgical facilities, and utilizing a pre-surgical team “Brief,” a pre-surgical team “Time-out” and a postsurgical team “De-Brief.”

• A common data collection system to measure and improve patient safety outcomes. The system should include uniform definitions, a consistent reporting structure, and accessibility and usability by all stakeholders—hospitals, care providers and medical society databases.

These recommendations will be used to finalize National Surgical Patient Safety Standards, develop surgical safety education curriculum proposals, and to identify surgical safety knowledge gaps and research priorities. “We believe that the implementation of these standards will guide surgical teams and members to achieve the ultimate goal of ensuring safe and optimal surgical patient outcomes,” said David D. Teuscher, MD, AAOS past president.

About the American College of Surgeons. The American College of Surgeons is a scientific and educational organization of surgeons that was founded in 1913 to raise the standards of surgical practice and improve the quality of care for all surgical patients.

Surveys Find Adults With Type 2 Diabetes Are More Willing to Take Action to Achieve A1C Targets Quicker than Physicians and Other Medical Professionals Perceive

Findings reveal that some patients are frustrated and discontinued medication because they were not reaching their individualized A1C target quick enough

Jacksonville, Florida—The American Association of Clinical Endocrinologists (AACE) announced results of two online surveys that identified differences in perceptions among adults living with type 2 diabetes as well as endocrinologists, primary care physicians and other medical professionals including nurse practitioners, physician assistants and pharmacists. The Perspectives in Diabetes Care surveys revealed that patients are more willing to take action to reach their individualized average blood glucose, or A1C, targets quicker than physicians and other medical professionals believe. More than half of adults living with type 2 diabetes polled are very willing to visit their physicians and other medical professionals more often and make multiple medication changes in order to achieve their A1C targets quicker, while less than one in five physicians and other medical professionals believe that patients would be very willing to take these actions.

Specifically, these findings reveal:

• While 57 percent of adults living with type 2 diabetes would be very willing to visit their physicians and other medical professionals more often, only 19 percent of physicians and other medical professionals polled believe they would be willing to do so.

• In addition, 52 percent of adults living with type 2 diabetes would be very willing to make multiple medication changes, though only 16 percent of physicians and other medical professionals think they would be very willing to make these changes.

These differing perceptions could play a role in the length of time it takes some patients to achieve their individualized A1C targets. The implications could be significant as more than 42 percent of patients surveyed have yet to achieve their A1C target and 77 percent of these respondents want to achieve it more quickly.
