Healthcare Disparities in the Management of Acute Cholecystitis: Impact of Race, Gender, and Socioeconomic Factors on Cholecystectomy vs Percutaneous Cholecystostomy

While percutaneous cholecystostomy (PC) is a recommended treatment strategy in lieu of cholecystectomy (CCY) for acute cholecystitis among patients who may not be considered good surgical candidates, reports on disparities in treatment utilization remain limited. The aim of this study was to investigate the role of demographic, clinical, and socioeconomic factors in treatment of acute cholecystitis. Patients with a diagnosis of acute cholecystitis who underwent CCY versus PC were reviewed from the U.S. Nationwide Inpatient Sample (NIS) database between 2008-2014. Measured variables including age, race/ethnicity, Charlson comorbidity index (CCI), hospital type/region, insurance payer, household income, length of stay (LOS), hospital cost, and mortality were compared using chi-square and ANOVA. Multivariable logistic regression was performed to identify specific predictors of cholecystitis treatment. A total of 1,492,877 patients (CCY:n=1,435,255 versus PC:n=57,622) were analyzed. The majority of patients that received PC were at urban teaching hospitals (65.2%). LOS was significantly longer with higher associated costs for PC [(11.1±11.0 versus 4.5±5.3 days; P
