Smoking Cessation

Opportunity for Physicians 70 percent of smokers want to quit. Without assistance only 5 percent are able to quit. Most try to quit do so on their own, without evidence- based programs; more than 95 percent relapse. Using evidence-based programs can more than double success rates.

Brief interventions Minimal interventions lasting less than 3 minutes increase overall tobacco abstinence rates. Every tobacco user should be offered at least a minimal intervention, whether or not he or she is referred to an intensive intervention. Even when patients are not willing to make a quit attempt, clinician-delivered brief interventions enhance motivation and increase the likelihood of future quit attempts. STRENGTH OF EVIDENCE: A

Ask and Act Ask every patient about tobacco use. Act to help them quit.

Patients unwilling to quit Use brief intervention to promote motivation (motivational interviewing) Patients unwilling to quit may: – Lack information about harmful effects or benefits of quitting – Lack financial resources – Have fears or concerns about quitting – Think they can’t quit PHS Clinical Practice Guideline: Treating Tobacco Use and Dependence: 2008 Update

Counseling
