A core set of quality performance indicators for HPB procedures: a global consensus for hepatectomy, pancreatectomy, and complex biliary surgery

Background: Surgery for hepatopancreaticobiliary (HPB) conditions is performed worldwide. This investigation aimed to develop a set of globally accepted procedural quality performance indicators (QPI) for HPB surgical procedures. Methods: A systematic literature review generated a dataset of published QPI for hepatectomy, pancreatectomy, complex biliary surgery and cholecystectomy. Using a modified Delphi process, three rounds were conducted with working groups composed of self-nominating members of the International Hepatopancreaticobiliary Association (IHPBA). The final set of QPI was circulated to the full membership of the IHPBA for review. Results: Seven “core” indicators were agreed for hepatectomy, pancreatectomy, and complex biliary surgery (availability of specific services on site, a specialised surgical team with at least two certified HPB surgeons, a satisfactory institutional case volume, synoptic pathology reporting, undertaking of unplanned reintervention procedures within 90 days, the incidence of post-procedure bile leak and Clavien-Dindo grade ≥III complications and 90-day post-procedural mortality). Three further procedure specific QPI were proposed for pancreatectomy, six for hepatectomy and complex biliary surgery. Nine procedure-specific QPIs were proposed for cholecystectomy. The final set of proposed indicators were reviewed and approved by 102 IHPBA members from 34 countries. Conclusions: This work presents a core set of internationally agreed QPI for HPB surgery.
