Textbook outcomes for liver resection: can a medium sized centre have acceptable outcomes?

Abstract

AbstractBackgroundTextbook outcome (TO) is an objective, composite measure of clinical outcomes in surgery. TO in liver surgery has been used in previous international studies to define and compare performance across centres. This study aimed to review TO rates following liver resection at a single institution. The secondary aim was to use a CuSum analysis to evaluate monitoring of performance quality over time for colorectal cancer liver metastases (CRCLM).MethodsAll patients undergoing liver resection for benign and malignant causes from Christchurch Hospital hepatobiliary unit between 2005 and 2022 were included. Textbook outcomes measures were the absence of; intraoperative incidents, Clavien‐Dindo >3 complication, 90 day re‐admission, 90 day mortality, R1 resection, and post‐operative bile leak/liver failure. Sequential CuSum analysis was performed to review achievement of TO in liver resections for colorectal cancer liver metastases (CRCLM).ResultsFour hundred and seventy‐eight patients were included in this study, 54 had resection for benign pathology, 290 for CRCLM and 134 for other malignancies. TO was achieved in 74% of cases overall, with rates for benign, CRCLM and other malignancy being 82%, 73% and 74% respectively (P = 0.405). CuSum analysis documented a deterioration in performance after patient 60, with return to baseline by end of study period.ConclusionsTO for liver resection in a medium sized centre in New Zealand are comparable to published rates. It is possible to use process control techniques like CuSum with the binary result of TO to monitor performance, providing opportunity for continuous improvement in surgical units.
