The Influence of Tobacco Load Versus Smoking Status on Outcomes Following Lobectomy for Lung Cancer in a Statewide Quality Collaborative.
Journal of Thoracic and Cardiovascular Surgery
BACKGROUND: Collaborative quality consortia can facilitate implementation of quality measures arising from clinical databases. Our statewide general thoracic surgery (GTS) collaborative investigated the influences of cigarette smoking status on mortality and major morbidity following lobectomy for lung cancer.
METHODS: Society of Thoracic Surgeons General Thoracic Surgery Database records were identified from 14 institutions participating in a statewide thoracic surgical quality collaborative between 2012 and 2017. We excluded patients with nonelective procedures, stage 0 tumors, American Society of Anesthesiologists class VI disease, and missing clinical characteristics. Outcomes analysis included the combined mortality and major postoperative morbidity rates and the influence of patient characteristics, including smoking status, on composite rate and on postoperative complications.
RESULTS: The study cohort included 2267 patient records for analysis. Overall combined mortality and major morbidity rate was 10.2% (n = 231). Postoperative 30-day mortality was 1.5%, and major morbidity 9.6%. Significant predictors of the combined outcome included male sex (P = .004), body mass index (P < .001), Zubrod score (P = .02), smoking pack-years (P = .03), and thoracotomy (P < .001). Higher American Society of Anesthesiologists disease class and advanced tumor stage were marginally associated with worse combined outcome (P = .06). Smoking status; that is, current, past (no smoking within 30 days), or never smoked, was not associated with worse combined outcome (P = .56) and had no significant influence on major complications.
CONCLUSIONS: Smoking status was not associated with worse outcomes; however, smoking dose (pack-years) was associated with worse combined mortality and major morbidity. A statewide quality collaborative provides constructive feedback for participating institutions and surgeons, promoting quality improvement in perioperative patient care strategies and improved outcomes.
