Peer review of mortality after pancreaticoduodenectomy in Australia

Abstract

BackgroundThe data within the Australian and New Zealand Audit of Surgical Mortality (ANZASM) provides a unique opportunity to consider the contributing factors to perioperative deaths as determined by peer review. Consideration of the factors contributing to mortality after pancreaticoduodenectomy (PD) can provide greater insight into how deaths can be prevented. MethodsANZASM data from 1 January 2010 to 30 Jun 2017 was reviewed and all deaths following PD were selected for analysis. Assessor's determination of whether management could have been improved were reviewed and classified into groups of significant clinical events using thematic analysis with a data driven approach. ResultsThe study included 87 deaths reported to ANZASM after PD. Forty-two major complications were considered significant clinical events in 29/84 (35%) of patients. The assessor determined that there was a delay in recognising a significant complication in 18/84 (21%) of patients. In 14/84 (17%) of patients, ANZASM assessment questioned the decision to operate. ConclusionMulti-disciplinary decision making is strongly recommended when deciding which patients to treat with PD. Late recognition, and therefore delayed action to treat complications, in almost a quarter of deaths is a significant finding that warrants consideration for clinicians involved in the postoperative care of PD patients.
