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.

A survey of primary care practices on their use of the intensive behavioral therapy for obese Medicare patients.
The objective of this study was to fill the gap in knowledge on systematic differences between primary care practices (PCP) that do or do not provide intensive behavioral therapy (IBT) for obese Medicare patients. The investigators concluded that although the Centers for Medicare and Medicaid Services established payment codes for PCPs to deliver IBT for obesity in 2011, very few providers submitted fee-for-service claims for these services after almost 10 years.

The joys and challenges of delivering obesity care: a qualitative study of US primary care practices.
The authors sought to explore the experience of providing obesity management among primary care clinicians and their team members involved with weight loss in primary care practices. They identified three primary themes: (1) clinicians and staff involved in obesity management in primary care believe that addressing obesity is an essential part of primary care services, (2) because providing obesity care can be challenging, many practices opt out of treatment, and (3) despite the challenges, many clinicians and others find treating obesity feasible, satisfying, and worthwhile. The authors concluded that, in order to improve the ability of clinicians and practice members to treat obesity, important changes in payment, education, and work processes are necessary.

Weight management in older adults.
This overview highlights the challenges and implications of measuring adiposity in older adults and the dangers and benefits of weight loss in this population and provides an overview of the new Medicare Obesity Benefit. In addition, it provide a summary of outcomes from successful weight loss interventions for older adults and discuss implications for advancing clinical practice.

Bariatric surgery in minority patients before and after implementation of a centers of excellence program.
This study compared rates of bariatric surgery for minority Medicare vs. non-Medicare patients before and after the 2006 implementation of a national coverage decision (NCD) restricting Medicare patients to centers of excellence for bariatric surgery. It found that the proportion of nonwhite Medicare patients receiving this procedure dropped from 27.5 percent before the NCD to 25.9 percent afterwards.
