Financial Burden of Postoperative Adverse Events Following Lobectomy: Cost Analysis From 10 High-Volume Canadian Hospitals.

objectivesLobectomy remains a cornerstone of curative intent treatment for lung cancer; however, postoperative adverse events (AEs) remain common, harmful, and costly. To support value-based quality improvement (QI) programmes, we sought to estimate the in-hospital costs of AEs following lobectomy and identify which complications are the primary cost drivers.

methodsLobectomy data from 10 Canadian hospitals were included (2017-2022). Annual lobectomy volume, demographics, length of stay (LOS), incidence, and severity of AEs were obtained from a prospectively collected national database. Using literature-derived index hospitalization costs of AEs, supported by Canadian Institution of Health Information database, estimates of annual AE costs were obtained (2025 CDN$).

resultsMean annual lobectomy volume 1150 (SD = 165): 44% male, aged 67 years (SD = 10.9), median LOS of 4 days (interquartile range [IQR] = 4), with minimally invasive surgery performed in 86%. Prolonged air leak (PAL) contributed 51% of total AEs occurrences, followed by atrial arrhythmia (13%), pneumonia (7.9%), reoperation (5.2%), atelectasis (3.9%), delirium (3.4%), transfusion (2.8%), respiratory failure (2.8%), empyema (2.2%), acute kidney injury (1.7%), and pulmonary embolism (1.2%), adding over $7.31 million (M) to hospital-level costs. PAL, mean annual incidence of 17%, was the strongest driver of costs. Extrapolated nationally, lobectomy-related AEs are estimated to contribute over $48 million in excess annual costs.

conclusionsPostoperative AEs following lobectomy impose substantial financial burdens, with PAL alone accounting for more than half of total costs. These findings underscore the need for value-based QI initiatives targeting high-impact AEs, requiring coordinated action among surgeons, hospital leadership, and policymakers.
