Simple advice has a small effect on cessation rates. Assuming an unassisted quit rate of 2 to 3%, a brief advice intervention can increase quitting by a further 1 to 3%. Additional components appear to have only a small effect, though there is a small additional benefit of more intensive interventions compared to very brief interventions.
The impact of routine advice on smoking cessation from family physicians.
Cigarette smoking continues to be a major health problem. Therefore, physicians have been asked to advise all their patients on the hazards of smoking. A controlled trial was undertaken to measure the impact of family physicians' advice to cigarette smokers during a routine office visit. No significant differences were found in the three measures used to determine outcome--desire to stop smoking, an attempt to stop and success in stopping--between the control and intervention groups. These results are discussed in relation to the health belief model, and suggestions are made on how to increase the impact family physicians could have on smoking cessation to their practices.
