This nationwide retrospective study investigated the impact of hospital volume and liver transplantation activity on postoperative mortality and failure to rescue after liver surgery. The study found that high-volume centers, defined as performing more than 25 liver resections per year, had lower rates of in-hospital mortality and failure to rescue, particularly related to specific complications. Liver transplantation activity did not influence these outcomes.
Background This nationwide retrospective study was undertaken to evaluate impact of hospital volume and influence of liver transplantation activity on postoperative mortality and failure to rescue after liver surgery. Methods This was a retrospective study of patients who underwent liver resection between 2011 and 2019 using a nationwide database. A threshold of surgical activities from which in-hospital mortality declines was calculated. Hospitals were divided into high- and low-volume centres. Main outcomes were in-hospital mortality and failure to rescue. Results Among 39 286 patients included, the in-hospital mortality rate was 2.8 per cent. The activity volume threshold from which in-hospital mortality declined was 25 hepatectomies. High-volume centres (more than 25 resections per year) had more postoperative complications but a lower rate of in-hospital mortality (2.6 versus 3 per cent; P < 0.001) and failure to rescue (5 versus 6.3 per cent; P < 0.001), in particular related to specific complications (liver failure, biliary complications, vascular complications) (5.5 versus 7.6 per cent; P < 0.001). Liver transplantation activity did not have an impact on these outcomes. Conclusion From more than 25 liver resections per year, rates of in-hospital mortality and failure to rescue declined. Management of specific postoperative complications appeared to be better in high-volume centres. This nationwide French study including 39 286 patients found that rates of in-hospital mortality and failure to rescue were lower in high-volume hospitals, defined as hospitals performing more than 25 liver resections per year. Notably, it described failure to rescue related to specific complications, which was less common in high-volume centres, proving the efficient management of postoperative complications in specialized centres.
