  • Stopped: an ongoing trial was terminated, suspended or withdrawn.

  • Minor: routine progress and housekeeping, such as sites added or enrollment closed.
A randomized control trial is planned to evaluate an interactive voice response (IVR) mediated follow-up and triage system, against usual care, to help smokers hospitalized with Coronary Heart Disease (CHD) to quit smoking. The investigators hypothesize that compared to usual care, participants in the IVR group will; a) have a significantly higher 7-day point prevalence abstinence rate at 26 and 52 weeks after hospital discharge, b) will have a higher rate of continuous abstinence at 26 and 52 weeks after hospital discharge, c) will use a greater number of proven effective interventions over time, and d) will develop greater self-efficacy with respect to smoking cessation, over time.
