Abstract

Abstract: Background: Evidence suggests index cholecystectomy (IC) in patients with acute cholecystitis is safe, has decreased hospital stay and is cheaper than delayed cholecystectomy (DC). Costs of cholecystectomy have not previously been investigated in New Zealand. The aim of this study was to compare cost of IC with DC for patients with acute cholecystitis. Methods: A retrospective analysis of adults admitted to Northland hospitals with acute cholecystitis between 1 January 2015 and 31 December 2019 who underwent subsequent cholecystectomy, was performed. Actual patient‐level costs were utilized for cost comparison between IC and DC. Factors associated with increased costs were assessed using multivariate analysis. Results: Two hundred and eleven patients were included in the study; 72 (34%) underwent IC and 139 (65%) DC. There was no significant difference in total cost for IC ($12 767) versus DC ($12 029) ( p = 0.192); this persisted on multivariate analysis. Patients having IC had more severe cholecystitis, and 90‐day representation rate following DC was 35%. Costs were increased by severity of cholecystitis, age, American Society of Anesthesiology score (ASA) and travel distance. Conclusion: This study showed there is no significant difference in cost between IC and DC for patients with acute cholecystitis in Northland, New Zealand. Severity, increasing age, ASA and travel distance were drivers of costs. To recognize the cost benefits of IC, it is likely that increased rates of IC are needed. Abstract : The costs of index and delayed cholecystectomy for acute cholecystitis were compared in a provincial centre. Over a 5‐year period, 72 underwent index cholecystectomy and 139 delayed, with no difference in total costs ($12, 767 versus $12, 029). Factors associated with increased costs were severity of disease, age, American Society of Anesthesiology score (ASA) and travel distance.
