BACKGROUND: Postoperative emergency department (ED) visits are a quality metric for bariatric surgical programs. Predictive factors of ED visits that do not result in readmission are not clear.
OBJECTIVES: We aimed to identify predictors of ED visits in patients without readmission after laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB).
SETTING: The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database.
METHODS: The MBSAQIP database was queried for patients who underwent LSG and LRYGB from 2015 through 2017. Patients were grouped by those who presented to the ED (ED group) and those who did not. ED visits analyzed included only those that did not result in readmission. Multivariable forward selection logistic regression was used to report adjusted odds ratios (AORs) with 95% CIs for ED visits.
RESULTS: Of 276,073 patients, 257,985 (93.4%) were in the group who did not present to the ED, and 18,088 (6.6%) were in the ED group. Most underwent LSG (71.9%) versus LRYGB (28.1%). Multivariable forward logistic regression identified outpatient treatment for dehydration (AOR, 22.26; 95% CI, 21.30-23.27; P < .001) as the most predictive factor of an ED visit, followed by urinary tract infection (AOR, 7.25; 95% CI, 6.22-8.46; P < .001), wound disruption (AOR, 4.63; 95% CI, 3.09-6.96; P < .001), and surgical site infection (AOR, 3.80; 95% CI, 3.38-4.28; P < .001).
CONCLUSIONS: Postoperative complications were the strongest predictors of ED visits after laparoscopic bariatric surgery. Quality improvement initiatives should target these variables to decrease postoperative ED visits.
