Relative incremental costs of complications of lobectomy for stage I non–small cell lung cancer

To evaluate the relative incremental cost of complications after lobectomy for stage I non–small cell lung cancer (NSCLC). Patients treated with open or video-assisted thoracoscopic surgery (VATS) lobectomy for stage I NSCLC between 2008 and 2014 were selected. A patient registry was queried for all complications recorded during a 90-day postoperative interval. Hospital cost data for each patient was concatenated with clinical data. Linear regression was used to assess the impact on direct hospital costs of specific complications. Among the 488 patients included in this study, 34% experienced ≥1 complication and 17% experienced ≥1 major complication. In patients experiencing complications, atrial arrhythmia (13%), prolonged air leak (8.6%), atelectasis (6.4%), and transfusion requirement (4.5%) were most common. Minor complications increased the relative cost of lobectomy by 29% (95% confidence interval [CI], 23%-34%; P
