National patterns in the treatment of smokers by physicians.

Abstract
CIGARETTE SMOKING is the single most important cause of death and disability in the United States.1 Because an estimated 70% of smokers visit a physician each year, physicians have the opportunity to promote smoking cessation.2 Brief physician counseling and the use of nicotine replacement therapy (NRT) have been shown to increase the smoking cessation rates of patients.3-5 The likelihood that a physician will counsel a smoker is increased by routine identification of a patient's smoking status in the medical record.6,7
