- To evaluate the effectiveness of a stepped smoking cessation intervention based on a transtheoretical model of change that uses the pharmacological and no-pharmacological methods proposed by evidence based Clinical Practice Guidelines for smoking cessation from primary care centers.
- To assess the health status change in relationship with the smoking cessation process.
DESIGN: Cluster randomized clinical trial
Unit of Randomization: Care basic unit (family physician or nurse that cares for the same group of patients). Intention to treat analysis.
PARTICIPANTS: 2911 smokers (ages 14-75 years) consulting for any reason to primary care centers
INTERVENTION: 6-month implementation of recommendations of a Clinical Practice Guideline that includes motivational consulting for smokers at the precontemplation - contemplation stage; brief intervention for smokers in preparation-action who do not want help; intensive intervention with pharmacotherapies for smokers in preparation-action who want help; and reinforcing intervention in the maintenance stage.
CONTROL: Usual care
MEASUREMENT: Self reported abstinence confirmed by an expired air carbon monoxide concentration of 10 parts per millions or less; Point prevalence at the end of intervention, 1 and 2 years after the beginning of intervention; Continuous abstinence rate for 1 year; Change of stage in the smoking cessation process; Health status measured by SF-36.
