  Purpose

Research Aims

The aims of this research study are to determine whether cost-free smoking cessation pharmacotherapy:

  1. Helps smokers with Transient Ischemic Attack (TIA) or stroke to quit smoking over the long-term, compared to simply providing a prescription for these medications;
  2. Is a more cost-effective alternative to providing a prescription only for these medications in this high risk population.

Hypotheses to be Tested

The hypotheses to be tested include the following:

  1. The CO-validated continuous abstinence rate at weeks 26 and 52 following a target quit date will be at least 10% higher for the cost-free smoking cessation pharmacotherapy intervention group compared to the prescription only usual care group;
  2. Cost-free smoking cessation pharmacotherapy will have a greater cost-effectiveness (i.e., cost/quit) than providing a prescription only.

Primary Outcome Measures:
  • The primary outcome will be the biochemically confirmed (exhaled CO < 10 ppm) self-reported continuous abstinence from weeks 12 to 52 following the target quit date. [ Time Frame: 52 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • The secondary outcome will be the biochemically confirmed (exhaled CO < 10 ppm) self-reported continuous abstinence from weeks 12 to 26 following the target quit date. [ Time Frame: 26 weeks ] [ Designated as safety issue: No ]
  • The total costs of smoking cessation treatment will be tracked over the duration of the study to determine the cost-effectiveness of providing cost-free pharmacotherapy for smoking cessation versus a prescription only. [ Time Frame: 3 years ] [ Designated as safety issue: No ]

Estimated Enrollment: 562

Arms Assigned Interventions
Experimental: Cost-Free Group Drug: Cost-Free Pharmacotherapy Group

Participants assigned to the cost-free pharmacotherapy group will be provided with a 12-week supply of NRT, or a 12-week supply of bupropion or varenicline.

Patients smoking 10 cigarettes or less will be prescribed 7mg/24hours for 12 weeks. Those who smoke 11- 20 cigarettes per day will be prescribed 14 mg/24 hours for 8 weeks and then nicotine patch 7mg for 4 weeks. Those smoking ≥ 20 cigarettes per day will be prescribed 21 mg/daily for 6 weeks and then nicotine patch 14mg/daily for 4 weeks and then nicotine patch 7 mg/daily for 2 weeks.

For patients who are prescribed varenicline, they will start the medication 8 days before the quit date using the following regime: Days 1-3: 0.5mg once/day; Days 4-7: 0.5 mg BID; Day 8-12 weeks 1.0 mg twice daily.

For patients who are prescribed bupropion, they will start the medication 8 days before the quit date using the following regime: Days 1-3: 150 mg daily (in the morning); Day 4-30: 150 mg BID for 3 months.

Prescription Only Group Other: Prescription Only Group
Participants assigned to the prescription only usual care group will be asked to have their prescription for smoking cessation pharmacotherapy filled at their own cost at their local community pharmacy

Detailed Description:

Smokers with Transient Ischemic Attack (TIA) or stroke attending a Stroke Prevention Clinic and willing to quit smoking will be randomly assigned (1:1) to either a prescription only (PO) usual care group or a cost-free (CF) pharmacotherapy experimental group. Participants assigned to the prescription only usual care group will be asked to have their prescription for smoking cessation pharmacotherapy filled at their own cost at their local community pharmacy. Participants assigned to the cost-free pharmacotherapy group will be provided with a 12-week supply of NRT, or a 12-week supply of bupropion or varenicline. The pharmacotherapy will be provided by the research nurse to the patient immediately. All participants will receive identical advice regarding smoking from the attending neurologist, nurse counseling for smoking cessation, and follow-up tracking and telephone-based support for up to 26 weeks after the target quit date. Non-treatment follow-up will continue to week 52 after the target quit date.
