About this study

Official title: An Interactive, Voice Response-Mediated, Follow-up and Triage System for Smoking Cessation in Smokers With Coronary Heart Disease

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.

Read the detailed description

Quitting smoking appears to be the single most effective intervention or treatment to reduce mortality in patients with Coronary Heart Disease (CHD). However, despite interventions, almost two-thirds of smokers resumed smoking in the year after hospitalization for CHD related illnesses; one-third resumed smoking within one month. A critical challenge for institution-level programs is how to provide consistent patient follow-up and linkage to community-based smoking cessation resources. Interactive voice response (IVR) technology has the potential to improve follow-up with smokers after hospitalization and to enhance triage to clinical support for smoking cessation. IVR uses natural language to place automated out-going calls that can pose questions regarding smoking status and progress with smoking cessation, that is then dropped into a database. A counselor is then able to link with the database and obtain information about the patient's smoking cessation needs and provide support as appropriate. A randomized control trial (RCT) is planned to evaluate whether an IVR system for follow-up and triage helps smokers hospitalized for CHD, quit smoking over 26- and 52-week follow-up periods. Participants are randomized into either a Usual Care or IVR group. Both groups will receive in-patient counseling and offer of nicotine replacement therapy. The IVR group will additionally receive a telephone call from the IVR system three, 14, 30, 60, 90, 120, and 150 days after hospital discharge. Variables that will be assessed at 26 and 52 weeks include: smoking status, both 7-day point-prevalent and continuous abstinence, as well as self-efficacy for smoking cessation, use of effective cessation resources and patient satisfaction (at 26 weeks).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Continuous Abstinence Rate

    Self-reported abstinence from any tobacco product during the time period.

    Measured: Baseline to 26 weeks

Secondary outcomes (2)
  1. Continuous Abstinence Rate

    Self-reported abstinence from any tobacco product during the time period.

    Measured: 27 to 52 weeks

  2. 7-day Point-prevalence Abstinence Rates

    no smoking (not even a puff) in the preceding 7 days

    Measured: At weeks 26 and 52.

Questions about this trial

What is this clinical trial studying?

A study testing Interactive Voice Response in people with Coronary Artery Disease, run by Ottawa Heart Institute Research Corporation at 1 site in Canada.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 30 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 30 Jun 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Continuous Abstinence Rate (time frame: Baseline to 26 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00449852, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Jun 2026.
