Abstract

Objective: To examine the effect of hospital volume of bariatric surgery on morbidity, mortality, and costs at academic centers. Summary Background Data: The American Society for Bariatric Surgery recently proposed categorization of certain bariatric surgery centers as "Centers of Excellence." Some of the proposed inclusion criteria were hospital volume and operative outcomes. The volume-outcome relationship has been well established in several complex abdominal operations; however, few studies have examined this relationship in patients undergoing bariatric surgery. Methods: Using the International Classification of Diseases, 9th edition, diagnosis and procedure codes, we obtained data from the University HealthSystem Consortium Clinical Data Base for all patients who underwent Roux-en-Y gastric bypass for the treatment of morbid obesity between 1999 and 2002 (n = 24,166). Outcomes of bariatric surgery, including length of hospital stay, 30-day read-mission, morbidity, observed and expected (risk-adjusted) mortality, and costs were compared between high-volume (>100 cases/year), medium-volume (50-100 cases/year), and low-volume hospitals (
