About

The aim of this study is to determine if providing smokers identified in family doctors offices with follow-up counselling enhances their success with quitting and the number of health professionals helping patients with quitting. Six to eight family medicine clinics will be involved in the study. We will compare the frequency of addressing smoking with patients and the proportion of smokers who are successful with quitting 16-weeks following the clinic appointment between practices. It is hypothesized that the addition of follow-up counseling to a multi-component smoking cessation intervention will improve smoking outcomes.

Full description

A family doctor's advice to quit has been shown to increase a smoker's motivation to quit. Despite the evidence supporting the importance of smoking cessation, there is a well-documented practice gap in the rates at which smoking cessation is being addressed by practitioners. The primary objectives of this research study are to determine whether adjunct telephone-based smoking cessation follow-up counselling when delivered as part of a multi-component intervention:

1. Increases the rate at which evidence-based smoking cessation interventions are delivered to smokers identified in family doctors offices, compared to providing only practice supports.
2. Increases smoking abstinence as measured three months after the estimated target quit date (i.e.16 weeks) compared to providing only practice supports.
3. Is more cost-effective (cost/quit) than providing only practice supports to family doctors offices.

A two-arm before-after matched-pair cluster randomized trial, will test the effectiveness of two strategies for integrating smoking cessation treatments into primary care practice routines and enhancing cessation. Six to eight family doctors offices will be randomized to either a practice support (PS) group, or a follow-up counseling (FC) group. From each of the intervention practices a cross-sectional sample of 50 eligible smokers will be recruited pre- and post-intervention to assess 5A's delivery and smoking abstinence.
