  Purpose

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.

Primary Outcome Measures:
  • smoking abstinence [ Time Frame: 16-weeks ] [ Designated as safety issue: No ]
    Self-report and biochemically validated point prevelence smoking abstinence


Secondary Outcome Measures:
  • cost-effectiveness [ Time Frame: 16-weeks ] [ Designated as safety issue: No ]
  • Rate of provider delivery of evidence-based smoking treatments [ Time Frame: exit survey on day of clinic visits ] [ Designated as safety issue: No ]
    Rates of providers, asking, advising, assessing, assisting, and arranging were assessed


Enrollment: 835
Study Start Date: January 2009
Study Completion Date: September 2010
Primary Completion Date: April 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Follow-up Counseling Arm
smoking cessation training for providers,practice tools for providers, patient quit plan, and follow-up telephone counselling for smokers
Behavioral: Smoking cessation training, support, and telephone follow-up
The CF group will receive the same smoking cessation training and practice support tools delivered to the PS group. In addition, patients in the FC group who are smokers and are willing to set a quit date within the next 30 days and who have set a quit date will be enrolled in an interactive voice response (IVR)-mediated telephone follow-up and counselling system. The IVR system will automatically contact patients via telephone 7 days before their TQD, and 5, 14, 30, and 60 days after their TQD to check the patients' smoking status, potential concerns, and their risk of relapse.
Active Comparator: Practice Support Arm
smoking cessation training for providers,practice tools for providers, patient quit plan for smokers.
Behavioral: smoking cessation intervention
Intervention practices will be provided with training in smoking cessation, and will be supported with integrating a waiting room screener for smoking and smoking consult form and patient quit plan into their practice routines.

Detailed 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.
