• Analysis of in-house mortality showed a clear association between hospital volume and outcome of lung cancer surgery in Germany. • The risk of death in hospitals with an annual mean of 99 cases a year was almost halved in hospitals with a mean annual volume of 6.6. cases. • The mortality among patients with complications was 16.7 % in hospitals with very low hospital volume and 12.9 % in hospitals with very high hospital volume. • Despite lower mortality and lower complications rates high volume hospitals had distinctly higher rates of technically complex surgery. • The occurrence and management of complications seems to be an essential factor influencing the volume–outcome association in lung cancer surgery. The literature reports that hospital caseload volume is associated with survival for lung cancer resection. The aim of this study is to explore this association in a nationwide setting according to individual hospital caseload volume of every inpatient case in Germany. This retrospective analysis of nationwide hospital discharge data in Germany between 2014 and 2017 comprises 121,837 patients of whom 36,051 (29.6 %) underwent surgical anatomic resection. Hospital volumes were defined according to the number of patient resections for lung cancer in each hospital, and patients were categorized into 5 quintiles based on hospital caseload volume. A logistic regression model accounting for death according to sex, age, comorbidity, and resection volume was calculated, and effect modification was evaluated using the Mantel–Haenszel method. In-house mortality ranged from 2.1 % in very high-volume centers to 4.0 % in very low-volume hospitals (p < 0.01). In multivariable logistic regression analysis, lower in-house mortality in very high-volume centers performing > 140 anatomic lung resections per year was observed compared with very low-volume centers performing < 27 resections (OR, 0.58; CI, 0.46 to 0.72; p < 0.01). This relationship also held for failure to rescue rates (12.9 vs 16.7 %, p = 0.01), although a greater number of extended resections were performed (23.1 vs. 14.8 %, p < 0.01). Hospitals with high volumes of lung cancer resections performed surgery with a higher ratio of complex procedures and achieved reduced in-house mortality, fewer complications, and lower failure to rescue rates.
