How effective are preoperative interventions on smoking cessation at the time of surgery and 12 months postoperatively, and on the incidence of postoperative complications?
This review included 8 studies addressing smoking cessation but only 5 of them addressed postoperative complications. Six trials testing brief interventions increased smoking cessation at the time of surgery, but failed to detect a statistically significant effect on postoperative morbidity. The optimal preoperative intervention intensity remains unknown.
Smokers have a substantially increased risk of postoperative complications. Preoperative smoking intervention may be effective in decreasing this incidence, and surgery may constitute a unique opportunity for smoking cessation interventions.
