BACKGROUND Studies using national data sets have suggested that insurance type drives a disparity in the care of emergency surgery patients. Large databases lack the granularity that smaller, single-institution series may provide. The goal of this study is to identify factors that may account for differences in care between Medicaid and non-Medicaid enrollees with appendicitis in central Massachusetts. METHODS All adult patients with acute appendicitis in an academic medical center between 2010 and 2018 were included. Sociodemographic and clinical characteristics were compared according to Medicaid enrollment status. Analyses were performed to assess differences in the frequency of operative treatment, time to surgery, length of stay, and rates of readmission. RESULTS The sample included 1,257 patients, 10.7% of whom (n = 135) were enrolled in Medicaid. The proportions of patients presenting with perforated appendicitis (28.9% vs 31.2%, P = .857) and undergoing laparoscopic appendectomy (96.3% vs 90.7%, P = .081) were similar between the 2 groups, as were length of stay (20 hours 30 minutes versus 22 hours 38 minutes, P = .109) and readmission rates (17.8% vs 14.5%, P = .683). Medicaid enrollees did experience somewhat greater time to surgery (6 hours 47 minutes versus 4 hours 49 minutes, P < .001). CONCLUSION Despite anticipated differences in popultion, the treatment of appendicitis was similar between Medicaid and non-Medicaid enrollees. Medicaid enrollees experienced greater time to surgery; however, further studies are needed to explain this disparity in care.
