Effectiveness of physician antismoking advice

Abstract

The Dartmouth Primary Care Cooperative Information (COOP) Project conducted a controlled trial on the impact of antismoking advice from office-based physicians. Eighteen primary care medical practices were randomly assigned to be intervention or customary care practices. Medical personnel assigned to the intervention practices were to systematically identify cigarette smokers (among patients aged 35 to 59 years making an office visit), advise them to quit smoking, and provide educational materials. A random sample of 258 smokers was identified and followed-up four months later. Intervention-group smokers were more likely to report being advised to quit smoking (77 percent versus 47 percent) and to attempt quitting (39 percent versus 31 percent), but had success rates similar to those of the other group (6 percent versus 7 percent). We conclude that the medical office is an excellent place to identify large numbers of smokers and initiate attempts at quitting, but find that simple antismoking information and advice are not enough to improve cessation rates.
