Trial 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. Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Cigarette smokers who are 18 years of age or older, who self-report smoking at least 10 cigarettes each day, and who are willing to accept random assignment are eligible to participate. Potential participants must agree to commit to the study for at least 24 months, be screened and agree to potentially participate in more intensive interventions to help them stop smoking, and agree to not seek other treatment for smoking cessation during the treatment phase of the study.

About this study

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.

Read the 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.

    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." 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.

Questions about this trial

What is this clinical trial studying?

A study testing Smoking Cessation Intervention in people with Tobacco Dependence, run by University of Tennessee at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 2 Dec 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Long term smoking cessation using both prolonged and point prevalence abstinence criteria (time frame: 24 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00170079, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Dec 2014.
