Readability of patient education materials for bariatric surgery.
This paper examined readability and reading level of online bariatric surgery and standardized perioperative electronic medical record (EMR) patient education materials (PEM). National organizations recommend that PEM not exceed a sixth grade reading level. One institution was used to assess readability of PEM. Text readability was assessed by seven validated instruments and mean readability scores calculated with standard deviations and compared using unpaired t-tests. A total of 32 webpages and seven EMR education documents were assessed. Web pages were overall assessed as "difficult to read" compared to "standard/average" readability EMR materials. All web pages were at or above high school reading levels, with the highest reading levels being pages with nutrition information and the lowest reading level patient testimonials. EMR materials were found to be at sixth to ninth grade reading level.

Identifying workflow disruptions in robotic-assisted bariatric surgery: elucidating challenges experienced by surgical teams.
The goal of this observational study was to investigate the impact of robotic bariatric surgery (RBS) on the surgical work system via the study of flow disruptions (FDs), or deviations from the natural workflow progression. Twenty-nine RBS procedures were observed at three sites; FDs were recorded in real time and subsequently classified into one of nine work system categories. FDs occurred approximately every 2.4 minutes and happened most frequently during the final patient transfer and robot docking phases of RBS. The coordination challenges that contributed most to these disruptions were associated with waiting for staff/instruments and readjusting equipment.

Racial variation in baseline characteristics and wait times among patients undergoing bariatric surgery.
The purpose of this study was to examine whether differences exist in baseline characteristics or access to care between white and non-white patients of bariatric surgery. The researchers utilized a statewide bariatric-specific data registry and assessed all patients of bariatric surgery who completed a baseline questionnaire prior to the operation and compared data among racial groups. A total of 73,141 patients were included with 25.5% self-identifying as non-white. Non-white males were the least represented group with 4% of all bariatric surgery cases performed. Despite having higher rates of college education, when compared to white patients non-white patients were more likely to be younger, disabled, and have Medicaid. Despite having higher rates of patients with a body mass index above 50 kg/m the median time from the first evaluation to surgery was longer among non-white patients (157 days vs. 127 days.) The study concluded that despite presenting with higher rates of severe obesity, when compared with white patients non-white patients of bariatric surgery are an extremely diverse group with greater socioeconomic disadvantages and longer wait times.

Bariatric surgery in Medicare patients: examining safety and healthcare utilization in the disabled and elderly.
The purpose of this study was to compare safety and healthcare use after sleeve gastrectomy versus Roux-en-Y gastric bypass in a national Medicare cohort. The researchers analyzed Medicare claims from 2012-2017 for 30,105 bariatric surgery patients receiving benefits due to age or disability and compared all outcomes between sleeve and bypass for each benefit group at 30 days, 1 year, and 3 years. The study found that among the disabled patients (n = 21,595), sleeve gastrectomy was associated with lower 3-year ED utilization, complications, reinterventions, rehospitalizations, and mortality. Cumulative expenditures were $46,277 after sleeve gastrectomy and $48,211 after gastric bypass. Among the elderly (n = 8510), sleeve was associated with lower 3-year ED utilization, complications, reinterventions, and rehospitalizations. Expenditures were $38,632 after sleeve gastrectomy and $39,270 after gastric bypass. Procedure treatment effect significantly differed by benefit group for paraesophageal hernia repair, revision, and mortality. The study concluded that healthcare utilization benefits of sleeve over bypass are maintained across Medicare elderly populations and Medicare disabled subpopulations.

Comparative safety of sleeve gastrectomy and gastric bypass: an instrumental variables approach.
This study compared the safety of sleeve gastrectomy versus gastric bypass surgery. Sleeve gastrectomy has become the most common bariatric surgery, rising from 52.6% in 2012 to 75% in 2016 among the cohort of 38,153 patients identified using commercially insured patients in the IBM MarketScan claims database. At 2 years from surgery, patients undergoing sleeve gastrectomy had fewer re-interventions (sleeve 9.9%, bypass 15.6%) and complications (sleeve 6.6%, bypass 9.6%), and lower overall healthcare spending ($47,891 vs $55,213), than patients undergoing gastric bypass. However, at the 2-year mark, revisions were slightly more common in sleeve gastrectomy than in gastric bypass (sleeve 0.6%, bypass 0.4%).

Medication use for obesity-related comorbidities after sleeve gastrectomy or gastric bypass.
The purpose of this comparative effectiveness research study was to evaluate prior laparoscopic sleeve gastrectomy or Roux-en-Y gastric bypass patients and compare the incidence of medication discontinuation and restart of diabetes, hypertension, and hyperlipidemia medications. The researchers reviewed the records of adult Medicare beneficiaries who underwent sleeve gastrectomy or gastric bypass between January 1, 2012, to December 31, 2018, and had a claim for diabetes, hypertension, or hyperlipidemia medication in the 6 months before surgery with a corresponding diagnosis. The study found that when compared with sleeve gastrectomy, gastric bypass was associated with a slightly higher 5-year cumulative incidence of medication discontinuation among 30,588 patients with diabetes medication use and diagnosis at the time of surgery, 5,081 patients with antihypertensive medication use and diagnosis at the time of surgery and 35,055 patients with lipid-lowering medication use and diagnosis at the time of surgery. Among the patients who discontinued medication, gastric bypass was also associated with a slightly lower incidence of medication restart up to 5 years after discontinuation. The researchers concluded that gastric bypass was associated with a slightly higher incidence of medication discontinuation and a slightly lower incidence of medication restart among patients who discontinued medication than sleeve gastrectomy.

Metabolic surgery may protect against admission for COVID-19 in persons with nonalcoholic fatty liver disease.
SARS-CoV-2 (COVID-19) disease causes significant morbidity and mortality through increased inflammation and thrombosis. Nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) are states of chronic inflammation and indicate advanced metabolic disease. The purpose of this observational study was to characterize the risk of hospitalization for COVID-19 in patients with NAFLD/NASH and evaluate the mitigating effect of various metabolic treatments.

Complications and readmissions associated with first assistant training level following elective bariatric surgery.
Little is known regarding the variation in training level and potential clinical impact of the first assistant in bariatric surgery. In this study, the investigators described the postoperative 30-day complications and readmissions following elective bariatric procedures by training level of the first assistant. The investigators concluded that variation in training level of the first assist during bariatric surgery had no influence on DSM or readmissions.

The role of commercial health insurance characteristics in bariatric surgery utilization.
The goal of this study was to understand relationships among insurance plan type, out-of-pocket cost sharing, and the utilization of bariatric surgery among commercially insured patients. Over 73,000 commercially insured members of the IBM MarketScan commercial claims database who underwent bariatric surgery from 2014-17 were retroactively reviewed. Findings showed that insurance plan types with higher cost sharing have lower utilization of bariatric surgery.

Modeling the impact of delaying bariatric surgery due to COVID-19: a decision analysis.
In this study, the investigators developed a decision analysis model to evaluate risks and benefits of delaying scheduled bariatric surgery during the novel coronavirus disease (COVID-19) pandemic. Their base case was a 45-year-old female with diabetes and a body mass index of 45 kg/m(2). They compared immediate with delayed surgery after 6 months to allow for COVID-19 prevalence to decrease. The investigators found that immediate and delayed bariatric surgeries after 6 months resulted in similar 20-year overall survival.

Peer assessment of operative videos with sleeve gastrectomy to determine optimal operative technique.
Global assessments of technical skill have been associated with surgical outcomes. More detailed understanding of which specific aspects of technique combine to make the "optimal" sleeve gastrectomy are necessary to help surgeons improve their practice. In this article, the investigators described their study in which the review of de-identified videos of practicing bariatric surgeons was conducted by a minimum of 10 peer surgeons. The videos were assessed on the technical quality of 9 operative maneuvers (ie mobilization of the fundus, stapler location, and sleeve width).

Suitability of administrative claims databases for bariatric surgery research - is the glass half-full or half-empty?
The authors assessed the availability and validity of claims-based weight-related diagnosis codes among bariatric surgery patients who underwent adjusted gastric banding, Roux-en-Y gastric bypass, or sleeve gastrectomy. They found that claims-based weight-related diagnosis codes had excellent validity before and after bariatric surgical operation but suboptimal availability after operation. Claims databases can be used for bariatric surgery studies of non-weight-related effectiveness and safety outcomes that are well-captured.

Post-operative complications and readmissions associated with smoking following bariatric surgery.
The link between smoking and poor postoperative outcomes is well established. Despite this, current smokers are still offered bariatric surgery. In this study, the investigators describe the risk of postoperative 30-day complications and readmission following laparoscopic sleeve gastrectomy and laparoscopic Roux-En-Y gastric bypass in smokers. The investigators concluded that smokers undergoing bariatric surgery experienced significantly worse 30-day outcomes when compared with non-smokers.

Association between surgeon practice knowledge and venous thromboembolism.
Venous thromboembolism (VTE) is the most common cause of mortality following bariatric surgery. This study aimed to determine practice patterns of VTE chemoprophylaxis among bariatric surgeons participating in a large statewide quality collaborative and compare the results of surgeon self-reported chemoprophylaxis prescription practices versus actual data from abstracted charts. They administered a 13-question survey to 66 surgeons to reveal VTE practice patterns such as medication type, dosage, timing, duration, and level of trainee involvement. They also examined the charts of all patients who had developed VTE during the study period and 15 other randomly selected patient charts per site. There was found to be a greater discordance between surgeon self-reported and actual perioperative VTE prophylaxis, but there was no significant discordance postoperatively. Greater perioperative discordance is associated with significantly increased risk of VTE.

Incidence and efficacy of stent placement in leak management after bariatric surgery: an MBSAQIP analysis.
The goal of this study was to evaluate the rates of use and efficacy of stent placement for postoperative leak following bariatric surgery. Using data from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program, findings showed that the use of stents can be effective; however, such use does not prevent reoperation and is associated with an increased likelihood of readmission. Recommendations included consideration of both technique and resource utilization when choosing a management pathway for leaks.

Lessons learned from developing a mobile app to assist in patient recovery after weight loss surgery.
This study examines the outcomes of patients recovering from weight loss surgery using a newly developed mobile app to help them recover successfully. The enrolled patients used the app for 30 days from July 2017 to October 2018. As the app was being used, it was updated. Ten patients were enrolled in the trial period with four using the initial version and six with the updated version. All patients were satisfied with the app and liked the notifications of updates. In the trial version only one patient completed at least 70% of the surveys, but five completed the surveys for the updated version. Next steps for the researchers is to conduct a pilot study with a larger set of patients.

Effect of new persistent opioid use on physiologic and psychologic outcomes following bariatric surgery.
In this study, the investigators sought to determine the relationship between new persistent opioid use and 1-year postoperative outcomes for patients undergoing bariatric surgery. The investigators concluded that new persistent opioid use is common following bariatric surgery and associated with significantly worse physiologic and psychologic outcomes. More effective screening and postoperative surveillance tools are needed to identify these patients, who likely require more aggressive counseling and treatment to maximize the benefits of bariatric surgery.

New onset alcohol use disorder following bariatric surgery.
Researchers sought to characterize the patients and incidence of alcohol use disorder (AUD) following sleeve gastrectomy (SG) compared to Roux-en-Y gastric bypass (RYGB). They found that the prevalence of alcohol use disorder in patients undergoing SG and RYGB was similar pre- and postoperatively, with the majority of patients developing AUD following their second postoperative year. The authors recommended understanding the timing and incidence of AUD in order to provide appropriate counseling and treatment.

Assessment of public attitudes toward weight loss surgery in the United States.
The authors designed a national cross-sectional survey to assess attitudes toward weight loss surgery in the US general population. Their survey results suggested that a large percentage of the population has negative attitudes toward weight loss surgery, including men and non-Hispanic black respondents, who were more likely to think that people who chose weight loss surgery were taking the easy way out. The authors recommended further research with respect to normalizing weight loss surgery as a reasonable option for managing obesity.

Variation in bariatric surgery episode costs in the commercially insured: implications for bundled payments in the private sector.
The authors described hospital-level variation in roux-en-Y gastric bypass and sleeve gastrectomy in Michigan. Their findings suggested that there are previously underappreciated differences in episode payment variation between bariatric surgery procedures. The authors also suggested that sleeve gastrectomy may be more amenable to cost containment under bundled payment initiatives by virtue of the greater share of variation explained by readmission and post-discharge payments.

Comparison of a Patient-Centered Weight Loss Program starting before versus after knee replacement: a pilot study.
This article reports the results of a randomized pilot study that assessed changes in weight during a Patient Centered Weight Loss Program (PACE) initiated either before or after knee replacement. The feasibility of recruiting and retaining participants over 26 weeks was also examined. Recruitment outreach was extended to patients scheduled for knee replacement. Sixteen participants were randomly assigned to a 14-session weight loss program that started either at least 6 weeks before surgery or at 12 weeks following surgery. The authors conclude that behavioral intervention is challenging but feasible in a knee replacement population. Preliminary evidence suggests that initiating a program 12 weeks after surgery produces greater weight losses at 26 weeks when compared to a program that begins before knee replacement.

Patients less likely to lose weight following a knee replacement: results from the osteoarthritis initiative.
The purpose of this study was to examine weight change patterns preoperatively and postoperatively among overweight/obese knee replacement patients. Overweight and obese patients initially lost weight during the interval including knee replacement; however, they were less likely to lose more than 2.5% of their weight in the 1 to 2 years immediately after the surgery.
