A critical analysis of surgical outcomes indicators in hepato‐pancreato‐biliary surgery: From crude mortality to composite outcomes

Abstract

BackgroundIndicators of surgical outcomes are designed to objectively evaluate surgical performance, enabling comparisons among surgeons and institutions. In recent years, there has been a surge in complex indicators of perioperative short‐term and long‐term outcomes. The aim of this narrative review is to provide an overview and a critical analysis of surgical outcomes indicators, with a special emphasis on hepato‐pancreato‐biliary (HPB) surgery.MethodsA narrative review of outcome measures was conducted using a combined text and MeSH search strategy to identify relevant articles focused on perioperative outcomes, specifically within HPB surgery.ResultsThe literature search yielded 624 records, and 94 studies were included in the analysis. Included papers were classified depending on whether they assessed intraoperative or postoperative specific or composite outcomes, and whether they assessed purely clinical or combined clinical and socio‐economic indicators. Specific indicators included in composite outcomes were categorized into three main domains: intraoperative metrics, postoperative outcomes, and oncological outcomes. While postoperative mortality, complications, hospital stay and readmission were the indicators most frequently included in composite outcomes, oncological outcomes were rarely considered.ConclusionsThe evolution of surgical outcomes has shifted from the simplistic assessment of crude mortality rates to complex composite outcomes. Whether the recent explosion of publications on these topics has a clinical impact in real life is questionable. Outcomes from the patient perspective, integrating social and financial indicators, are not yet integrated into most of these composite analytical tools but should not be underestimated.
