Smoking cessation: integration of behavioral and drug therapies -- american family physician
Smoking Cessation: Integration
of Behavioral and Drug Therapies
ROBERT MALLIN, M.D., Medical University of South Carolina, Charleston, South Carolina
Family physicians should take advantage of each contact with smokers to encourage and
support smoking cessation. Once a patient is identified as a smoker, tools are available to
assess readiness for change. Using motivational interviewing techniques, the physician can
tion handout on howto stop smoking, writ-
help the patient move from the precontemplation stage through the contemplation stage
to the preparation stage, where plans are made for the initiation of nicotine replacement
and/or bupropion therapy when indicated. Continued motivational techniques and sup-
port are needed in the action stage, when the patient stops smoking. Group or individual
behavioral counseling can facilitate smoking cessation and improve quit rates. Combined
use of behavioral and drug therapies can dramatically improve the patient’s chance of quit-
ting smoking. A plan should be in place for recycling the patient through the appropriate
stages if relapse should occur. (Am Fam Physician 2002;65:1107-14,1117. Copyright 2002

Interventions: Educate the patient about the effects of smoking, introduce
ambivalence (inquire about decision to continue smoking), express concern, and recommend quitting.
Physician statement introducing ambivalence: “Today most people agree that
smoking is not good for your health. What do you think about that?”
Physician statement expressing concern and encouraging contemplation: “I am
concerned about your health and believe you should stop smoking. I am wondering how I can help you with that.”

Interventions: Assess positive and negative thinking about smoking.
Physician statement resolving ambivalence: “Your cough will improve when
(the patient wants to quit smoking)
Interventions: Set a quit date, select smoking cessation strategies, determine dosage
of nicotine replacement if indicated, identify triggers, gather social support for quitting, and begin bupropion (Zyban) if indicated.
Physician statement encouraging planning and action: “Let’s set a date for you to
quit smoking and make plans for how you can do it.”

Interventions: Begin nicotine replacement and continue bupropion.
Physician and staff maintain frequent contact with the patient to provide support
and help provide solutions for dealing with specific triggers.
