Review Meta Analysis
Stopping smoking shortly before surgery and postoperative complications: a systematic review and meta-analysis.
To examine existing smoking studies that compare surgical patients who have recently quit smoking with those who continue to smoke to provide an evidence-based recommendation for front-line staff. Concerns have been expressed that stopping smoking within 8 weeks before surgery may be detrimental to postoperative outcomes. This has generated considerable uncertainty even in health care systems that consider smoking cessation advice in the hospital setting an important priority. Smokers who stop smoking shortly before surgery (recent quitters) have been reported to have worse surgical outcomes than early quitters, but this may indicate only that recent quitting is less beneficial than early quitting, not that it is risky. ⋯ Existing data indicate that the concern that stopping smoking only a few weeks prior to surgery might worsen clinical outcomes is unfounded. Further larger studies would be useful to arrive at a more robust conclusion. Patients should be advised to stop smoking as early as possible, but there is no evidence to suggest that health professionals should not be advising smokers to quit at any time prior to surgery.
