Telephone and Web-based Teen Tobacco Cessation in HMOs (QWIThelper)

Health maintenance organizations have the mission, incentive, communication tools, and credibility with patients to reach out to teen members who use tobacco. The overall aim of this project is to refine and test both the potential reach and the efficacy of tobacco cessation support using a proactive telephone quitline combined with an interactive Web-based program for teens within a managed care environment. As part of a clinician-directed outreach effort, we will work closely with pediatric clinicians to maximize the program's reach into the teen smoker population as identified through the electronic data base of a large HMO. We will use letters and proactive outreach calls to assess current smoking status and recruit 600 15- to 18-year-old teen smokers who are interested in quitting and would be willing to receive cessation support via telephone and the Web. A second aim will be to randomly assign interested teen smokers to receive a proactive telephone- and Web-based tobacco cessation program or access to a website with cessation materials (control condition) to test the efficacy of the program on long-term cessation rates at 6- and 12-months. We will use several process measures to assess our ability to implement and consistently deliver both the telephone and Web components of the intervention. We will measure mediating variables to determine they support the hypothesized linkages between the theoretical constructs described by our cognitive behavioral model of action. An effective managed care partnership with clinicians to assess, recruit, and intervene with teen smokers would be of great interest to clinicians and health plan managers, highly exportable, and would be given high priority for implementation at the population level.

Our specific aims are as follows:

1. Compare the population-based recruitment yields and costs of three proactive outreach approaches: 1) outreach calls only to those teen smokers who are seen, advised, and referred to us by their clinician; 2) outreach calls to a random sample of teens shown as being smokers in the EMR; and 3) outreach calls to a sample of all teens
2. Assess efficacy/effectiveness in a randomized trial with 600 teen smokers to evaluate the hypothesis that proactive telephone-based counseling integrated with an interactive website will increase 6- and 12-month abstinence rates (30-day point prevalence) relative to a control condition receiving mailed cessation materials alone
3. Assess the hypothesis that the telephone and web-based intervention will improve longer-term maintenance of abstinence at an 12-month follow-up point compared to the control condition
4. Describe use patterns for key intervention process measures (e.g., calls completed, use of website) and determine if intervention affects outcome through theoretical mediators (e.g., pros/cons, stage, efficacy)
5. Determine the total costs of the telephone and web-based program from the perspective of the HMO and replication costs in other settings, and report costs as incremental costs per member per month, per program participant, and per quit.
