OBJECTIVE:: To determine the impact of length of stay upon 30-day outcomes. BACKGROUND:: It has been recommended the goal length of stay (LOS) after laparoscopic Roux-en-Y gastric bypass (LRYGB) should be 1 day to improve resource utilization. This study's aim was to assess LRYGB outcomes by LOS. METHODS:: Data were obtained from the BOLD (Bariatric Outcomes Longitudinal Database) for 51,788 laparoscopic gastric bypass (LRYGB) procedures performed between 2007 and 2010. Logistic regression models were used to evaluate age, sex, race, body mass index, insurance status, comorbidities, and LOS as predictors for 30-day mortality, serious complications, and readmissions. RESULTS:: Overall patient demographics were as follows: median age, 45 years; median body mass index, 46.3 kg/m; % female, 78.6; % white, 77.8; % private insurance, 86.2; and % comorbidities more than 5 (39.1%). Overall, 30-day outcomes included mortality, 0.1%; serious complications, 0.5%; and readmissions, 3.8%. median LOS was 2 days, and the distribution of LOS was as follows [n (%)]: 0 (1.0), 1 (18.4), 2 (59.0), 3 (17.5), and 4 (4.1). Using the median LOS 2 days as reference, the logistic regression analysis revealed that ambulatory LOS of was significantly associated with increased risk of 30-day mortality (odds ratio: 13.02; P < 0.0001) as was LOS 1 day (odds ratio: 2.02; P < 0.0552). For LOS of 0 day, there was a trend toward an increase in the rate of 30-day serious complications (odds ratio: 1.9; P < 0.16). There was no significant trend between LOS status and 30-day readmission rates. CONCLUSIONS:: In this large, prospective, clinical database, LOS of 1 day or less for LRYGB patients was significantly associated with an increased risk of 30-day mortality and a trend toward increased risk of 30-day serious complications.
