Design and Objective: The Cessation Screening Project is a 4-factor factorial screening experiment (i.e., 2x2x2x2 = 16 experimental conditions) designed to identify the most promising intervention components that are especially effective and cost-effective with regard to their main and interactive effects on 12-month biochemically verified abstinence. This design will allow us to: 1) detect main effects and interactions within the factorial experiment and identify especially effective regimens for varenicline and for (Combination Nicotine Replacement) C-NRT; 2) compare the relative effectiveness of varenicline and C-NRT; and 3) identify the most effective and cost-effective counseling intensity to use with the optimized medication regimens. Finally, these results will allow us to identify two optimized treatment packages for use with primary care smokers interested in quitting: packages that include both counseling and pharmacotherapies optimized on the bases of effectiveness and cost. Recruitment and Participants: Participants (N=608) will be primary care patients from 12 primary care clinics in two Wisconsin healthcare systems. Smokers will be identified via the healthcare system electronic health record (EHR). All EHR-identified smokers in a clinic will receive a mailed invitation to find out more about smoking treatment by calling a healthcare system Care Manager (CM). In addition, using an opt-out strategy, Medical Assistants (MAs), using an EHR-guided prompt, will inform all identified smokers seen at in-person or tele-health visits that they will be contacted by the CM unless the participant indicates s/he wants to opt-out. The participant contact information will then be automatically sent to the CM unless the participant opts out; the investigators have developed and used this workflow successfully in their past research. The CM will call and tell patients about the smoking cessation options available for them including the availability of this smoking cessation study. If patients are interested, the CM will obtain oral assent for screening and sharing contact, primary care team, and screening data with the research team before screening patients for eligibility. Eligible patients will learn more about the study and have a chance to ask questions and provide verbal informed consent. Finally, participants will complete a brief series of questions and then the CM will schedule a call with the study staff (i.e., a Health Counselor) in the database to initiate treatment and complete study assessments. Participants interested in quitting but not eligible for this study will be electronically referred to the Wisconsin Tobacco Quit Line and/or their primary care provider (PCP) by the CM. Those who agree to and pass the screening for the inclusion/exclusion criteria for study participation will be asked to complete an oral consent and HIPAA authorization process next. After the patient provides oral consent, the CM will notify the patient's PCP via EHR that the patient has volunteered for a study with C-NRT or varenicline. The PCP will notify the CM via the EHR that the patient is medically eligible to receive either agent, as required by the collaborating healthcare systems. This will occur within 5 business days. The PCP will be notified via EHR of the patient's treatment assignment and of study-related serious adverse events or adverse events that prompt medication discontinuation that may occur. Care coordination with the PCP will occur via Tobacco Care Manager entry of data in the patient EHR. Procedures and Measures: At the second study call, participants (N=608) will be randomized to one level of each of 4 factors: 1) Medication Type (Varenicline vs. C-NRT), 2) Preparation Medication (4 weeks vs. Standard), 3) Medication Duration (Extended vs. Standard), and 4) Counseling (Intensive vs. Minimal). Participants will be told their treatment condition at Call 2, set a target quit date (TQD), and instructed how to use their study medications. Medications will be mailed following this call, along with a handout that describes: 1) when to begin taking study medication; 2) the type and doses involved; 3) how and when to obtain the next month's medication; and 4) complete instructions on proper medication use, including information from the package insert and contact information if they have questions regarding their medication and/or symptoms they experience. Participants will be mailed all Preparation Medication as well as one month of post-quit study medication after Call 2. They will need to call in to a study line to request that more medication be mailed to them (Standard Duration participants will call one time to receive their final 2 months of medication; Extended Duration participants will call once to get 2 additional months of medication and again to get the remaining 3 months of study medication). Participants will also receive a counseling handout with their medications; those randomized to intensive counseling will receive a Quit Plan listing their target quit day and when they start the medications and those randomized to minimal counseling will receive the mobile health (mHealth) handout. Participants will complete phone assessments one week pre-quit, during the first week post-target quit date (TQD) and at Weeks 2, 4, 12, 20, 26, and 52 post-TQD. Outcomes: The primary outcome for this study is biochemically confirmed, point-prevalence abstinence at 12 months post-TQD (Primary Aim 1). The secondary outcome is cost effectiveness in which the costs of implementing each intervention (minus research-related costs) will be computed from a payer perspective. Costs will be combined with the intent-to-treat biochemically verified 7-day point prevalence abstinence at 12 months post-TQD to determine the cost per quit.
