Prolonged Smoking Cessation Using Prescription Step Care

Not Applicable

Completed

• Conditions: Tobacco Dependence

• Registration Number: NCT00170079
• Lead Sponsor: University of Tennessee

Brief Summary

Smoking is the number one preventable cause of morbidity and mortality in this nation. Unfortunately, more than 50% of those who quit following a smoking cessation intervention typically relapse within two weeks, with approximately 80% relapsing within six months. Therefore, tobacco use can be conceptualized as a chronic condition. As with many chronic medical problems, tobacco use interventions may benefit from a step care approach to treatment.

A total of 400 adult smokers will be enrolled in the study. Participants will be randomly assigned to one of two treatment conditions consisting of: 1) A State of the Art Smoking Cessation Intervention + Recycling or: 2) A State of the Art Smoking Cessation Intervention + Step Care. Long term smoking cessation will be assessed by self-report, exhaled carbon monoxide levels, and salivary cotinine. The primary endpoint of the study will be smoking abstinence rates at two-year follow-up. It is predicted that long-term cessation rates will be significantly higher in the step care condition than for those assigned to the recycling group.

Detailed Description

A common approach to increasing long-term adherence and control of chronic medical problems such as hypertension in both general and preventive medicine is the concept of step care. Despite a high degree of interest in applying the step care model to smoking cessation (Abrams et al., 1996; Hughes, 1994), little empirical work has been conducted utilizing this treatment approach. The purpose of this study is to evaluate the long-term efficacy of a step care model for smoking cessation that is disseminable in primary care settings. With that introduction, we propose the following specific aims:

Aim 1: To enroll approximately 400 adult cigarette smokers recruited mainly from primary care settings;

Aim 2: To randomize these participants to: 1) State of the Art Smoking Cessation + Recycling or 2) State of the Art Smoking Cessation + Step Care; and

Aim 3: To evaluate the long-term (24 months post-randomization) relative success of the interventions. It is predicted that long-term cessation rates will be significantly higher in the step care condition.
