Improving smoking cessation support for Quebec's smokers: an evaluation of Quebec's telephone quitline

Quitlines are an important and widespread intervention that support smokers in their efforts to quit smoking and engage them into treatment services. Quebec's quitline, called "la ligne J'ARRÊTE", has been in operation since 2002. The objectives of this study were to evaluate treatment reach, provide a description of caller characteristics and to provide results on cessation outcome measures for Quebec's smoking cessation quitline.

We collected data at intake, assessing new caller volume, caller characteristics and treatment reach. We used a one-group quasi-experimental design to assess 30-day and six-month quit rates, at six-month follow-up. Intake data were collected for 1292 new quitline callers, 18 years of age and older, over a one-year period.

Results indicated that the service reached 9 in 10 000 Quebec smokers. With respect to the total population of smokers in Quebec, the quitline reached proportionately higher numbers of smokers who were women, were 55 years of age and older and had a high school diploma or less. At follow-up, the 30-day point prevalence abstinence rate was 26.7%, while the six-month prolonged abstinence rate was 18.8%.

These results indicate that the quitline contributed to helping callers quit smoking. They are in line with findings for other quitlines in Canada and the United States. However, quitline reach is comparatively limited, suggesting that additional investment in promotional efforts and research into ways of recruiting underserved populations into the service would increase public health impact.
