Preoperative smoking interventions effectively change patient smoking habits before surgery. However, evidence linking this to reduced postoperative complications is limited and varies by intervention type and duration.

Area of Science:

  • Anesthesiology
  • Addiction Medicine
  • Surgical Outcomes

Background:

  • Smokers face significantly higher risks of intra- and postoperative complications.
  • Preoperative smoking cessation interventions may reduce these risks due to heightened patient motivation.
  • The period before surgery presents an opportune time for smoking cessation support.

Purpose of the Study:

  • To evaluate the impact of preoperative smoking intervention on smoking cessation in the postoperative period and long-term.
  • To determine if smoking cessation influences the incidence of postoperative complications.

Main Methods:

  • Searched Cochrane Tobacco Addiction Group specialized register, MEDLINE, EMBASE, and CINAHL for randomized trials.
  • Included trials recruiting smokers pre-surgery, offering cessation interventions, and measuring abstinence.

  • Considered trials assessing smoking cessation effects on intra- and postoperative complications.

    • Main Results:

    • Four trials met inclusion criteria; all reduced preoperative smoking, but effect sizes varied.
    • Two trials reported on complications, with heterogeneous results: one showed significant reduction, the other no difference.
    • Longer-term smoking cessation beyond the perioperative period was not significant in trials with extended follow-up.

    Conclusions:

    • Preoperative smoking interventions effectively modify perioperative smoking behavior.
    • Direct evidence for smoking cessation reducing complications is limited, based on two small trials with conflicting outcomes.
    • The effect on complications may depend on the timing of intervention, degree of smoking reduction, and surgical type.
