Multicenter Study Comparative StudyNational study of the effect of patient and hospital characteristics on bariatric surgery outcomes.
The influence of patient and hospital demographics on gastric bypass (GB) outcomes is unknown. We analyzed year 2000 data from the Nationwide Inpatient Sample database for all GB patients. In 2000, 5876 GB were performed in the 137 sample hospitals (M:F, 14%:86%). ⋯ Increasing age, male gender, and surgery performed in large hospitals are predictors of morbidity. Male gender and postoperative complications predict increased mortality. Neither comorbidities, race, payer, income, hospital academic status, location, nor hospital volume affect the outcome after GB.
