Surgical Management of Obesity in Brazil: Proposal for a Value-Based Healthcare Model and Preliminary Results

To describe the implementation and 1-year results of a value-based bariatric surgery program in Brazil.

The study was conducted at a private hospital in São Paulo, Brazil (Hospital Alemão Oswaldo Cruz). A value-based healthcare program was implemented by designing an episode of care for eligible patients and developing a bundled payment model in which a single payment was made for the bariatric surgery covering the preoperative workup and ending 30 days after discharge. Assessment of outcomes included complication rate, hospital length of stay, intensive care admissions, reoperations, readmissions, and visits to the emergency department in the 30-day postoperative period. The results were compared with real-world evidence retrieved from a Brazilian private insurance database containing information on bariatric procedures performed in similar institutions (benchmark group).

Eighty-three patients were enrolled in the value-based healthcare program (80.7% women; 18.0% with type 2 diabetes mellitus; 31.0% with high blood pressure). The mean age was 40.9 years, and body mass index was 42.1 kg/m². The outcomes recorded in the benchmark group versus the value-based healthcare group involved complication rate, 2.6% versus 1.4% (P = 0.69); length of stay, 2.5 versus 2.0 days (P = 0.0001); intensive care admissions, 4.0% versus 1.2% (P = 0.31); emergency care visits, 15.0% versus 6.0% (P = 0.04); and readmissions, 2.3% versus 0 (P = 0.35), with an estimated cost reduction of 7.1%.

These initial results showed favorable surgical and 30-day outcomes, demonstrating the benefits of a value-based approach for the surgical management of obesity and its comorbidities.
