Abstract

The World Society for Emergency Surgery determined that for appendicitis managed with appendectomy, there is a paucity of evidence evaluating costs with respect to disease severity. The American Association for the Surgery of Trauma (AAST) disease severity grading system is valid and generalizable for appendicitis. We aimed to evaluate hospitalization costs incurred by patients with increasing disease severity as defined by the AAST. We hypothesized that increasing disease severity would be associated with greater cost. Single-institution review of adults (≥ 18 years old) undergoing appendectomy for acute appendicitis during 2010-2016. Demographics, comorbidities, operative details, hospital stay, complications, and institutional cost data were collected. AAST grades were assigned by two independent reviewers based on operative findings. Total cost was ascertained from billing data and normalized to median grade I cost. Non-parametric linear regression was utilized to assess the association of several covariates and cost. Evaluated patients (n = 1187) had a median [interquartile range] age of 37 [26-55] and 45% (n = 542) were female. There were 747 (63%) patients with Grade I disease, 219 (19%) with Grade II, 126 (11%) with Gra...Continue Reading
