Postoperative Mortality Following Lung Cancer Surgery

Abstract

hypothesise that procedural volume (both surgeon and hospital) is not associated with improved patient outcomes in isolated coronary artery bypass grafting surgery in Australia. Methods: Data from the Australian and New Zealand Society of Cardiac and Thoracic Surgeons (ANZSCTS) registry including 43,000 patients, 23 hospitals and 122 surgeonhospital combination from 2001 to 2010 was reviewed. 20,619 patients with isolated CABG surgery were included. Two variables of interest were hospital-specific surgeon volume and hospital volume. Hierarchical logistic regression was performed after adjustment for other risk factors. Outcome measures included operative mortality and morbidity (deep sternal wound infection, new stroke, new renal failure). Results: Hospital volumes ranged from 96 to 429 isolated CABG procedures and hospital-specific surgeon volumes ranged from <10 to 129. Both hospital and hospital-specific surgeon volume were not associated with improved mortality or morbidity outcomes to a significance level of p 0.01.
