Physician advice can slightly increase smoking cessation rates. While intensive interventions show a marginal benefit over minimal advice, additional aids offer little extra help in quitting smoking.

Area of Science:

  • Public Health
  • Clinical Medicine
  • Behavioral Science

Background:

  • Healthcare professionals routinely advise patients to stop smoking to improve health.
  • Smoking cessation advice can range from brief interventions to more intensive programs.

Purpose of the Study:

  • To evaluate the effectiveness of physician advice in promoting smoking cessation.
  • To compare minimal versus intensive physician interventions for smoking cessation.
  • To assess the impact of anti-smoking advice on mortality rates.

Main Methods:

  • Systematic review of randomized controlled trials (RCTs) of smoking cessation advice from medical practitioners.
  • Searches conducted in Cochrane registers up to October 2000.
  • Meta-analysis used for pooled data, with abstinence assessed at least six months post-advice.

Main Results:

  • Thirty-four trials involving over 27,000 smokers were analyzed.
  • Brief physician advice significantly increased smoking cessation odds (OR 1.69), yielding an absolute cessation rate increase of ~2.5%.
  • Intensive interventions showed a small advantage over minimal advice (OR 1.44); aids provided little additional benefit. No significant effect on mortality was found.

Conclusions:

  • Simple physician advice has a small but significant positive effect on smoking cessation.
  • More intensive interventions are marginally more effective than minimal advice.
  • Additional maneuvers and aids appear to have a limited impact on cessation rates.
