Preoperative Smoking-Cessation Interventions to Prevent Postoperative Complications: A Quality Assessment and Overview of Systematic Review Evidence.

Multiple systematic reviews have investigated the effectiveness of preoperative interventions for smoking-cessation, although relatively few have focused on the prevention of surgical complications. This overview of systematic reviews aimed to describe the types of smoking interventions studied to prevent postoperative complications, summarize the results, and evaluate the quality of the reviews and strength of evidence to inform clinicians, health practitioners, policy developers, and government bodies. Comprehensive searches of Cochrane Library, MEDLINE, EMBASE, CINAHL, and Johanna Briggs Institute databases were conducted to identify systematic reviews of preoperative smoking-cessation interventions to prevent surgical complications (inception-May 14, 2024).
