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.

The obese colorectal surgery patient: surgical site infection and outcomes.
The purpose of this study was to understand the association between BMI and 30-day postoperative outcomes, including surgical site infection, among patients undergoing colorectal surgery. The study found that patients with increasing BMI showed an incremental and independent risk for adverse 30-day postoperative outcomes, especially surgical site infections.

Understanding barriers and facilitators to healthy eating and physical activity from patients either before and after knee arthroplasty.
The researchers sought to identify patient-reported barriers and facilitators to healthy eating and physical activity among patients before or after knee arthroplasty. They found that identifying specific eating and activity barriers and facilitators provides critical insight from the patient perspective, which will aid in developing weight management programs during rehabilitation for knee arthroplasty patients.

Early major complications after bariatric surgery in the USA, 2003-2014: a systematic review and meta-analysis.
This systematic review and meta-analysis assesses <30-d major complications associated with bariatric procedures, including anastomotic leak, myocardial infarction and pulmonary embolism. The review included 71 studies conducted in the USA between 2003 and 2014 and 107,874 patients undergoing either gastric bypass, adjustable gastric banding or sleeve gastrectomy, with mean age of 44 years and pre-surgery body mass index of 46.5 kg m(-2).

Site-specific approach to reducing emergency department visits following surgery.
The aim of this study was to explore the efficacy of current bariatric perioperative measures at reducing emergency department (ED) visits following bariatric surgery in the state of Michigan. The investigators concluded that current practices aimed at reducing ED visits appeared to be ineffective. They suggested that due to heterogeneity in patient populations and local infrastructure, a more tailored approach to ED visit reduction may be more successful.

Physiologic and psychological gender differences in bariatric surgery.
This paper aims to describe differences in bariatric surgery outcomes by gender and to understand the physiologic and psychological differences that may explain this gender gap. It concludes that, despite significantly lower weight loss and increased complication rates, males tend to have markedly higher satisfaction and psychological well-being scores than females.

Reduced risk of acute exacerbation of COPD after bariatric surgery: a self-controlled case series study.
Little is known about the impact of weight reduction on chronic obstructive pulmonary disease (COPD)-related outcomes in patients who are obese. This study found that the risk of an ED visit or hospitalization for acute exacerbation of COPD substantially decreased after bariatric surgery in patients who are obese. This observation suggests the effectiveness of substantial weight reduction on COPD morbidity.
