Preoperative intervention for smoking cessation: A systematic review

Background: Smoking is associated with increased postoperative complications. Pre-surgical smoking cessation remains a challenge. Our aim was to summarize pre-hospital smoking cessation interventions and impact on smoking cessation rates. Methods: Independent review of English language articles identified from systematic searches of MEDLINE, PubMed, PsycInfo, Embase, Web of Science, and Cumulative Index to Nursing & Allied Health Literature databases from 1998 to 2019 was performed (PROSPERO registration number CRD42021247927). Studies of adult patients enrolled in a pre-hospital smoking cessation intervention were included. Studies with historical controls or only self-reported outcomes were excluded. Results: Nine articles including 1762 patients were identified. Exhaled CO was used to confirm cessation. Six studies reported smoking status day of surgery. Interventions included NRT, hand-held technology, e-cigarettes, decision aids/counseling and medications. Four studies demonstrated a difference in smoking cessation rates. Ethics and study appraisal were assessed using ROB2. Conclusions: Based on the variability of interventions, settings, and outcomes, best practice for successful prehospital smoking cessation in surgery clinics would benefit from ongoing investigation.
