Using IVR to Maintain ACS Patients on Best Practice Guidelines

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to determine whether interactive voice response (IVR) technology can be used to bring post discharge care for acute coronary syndrome (ACS) closer to best practice guidelines (BPGs). The study hypothesis is that ACS patients who are contacted by IVR technology will be more likely to receive care as recommended in the BPGs than those followed by usual care.

Detailed Description
-----------------
Acute coronary syndrome (ACS) is a significant public-health problem in Canada and worldwide with 20,000 Canadians dying of myocardial infarction and 42,000 dying of coronary artery disease in 1999. Large clinical trials have provided evidence for the development of standardized best practice guidelines (BPG) and compliance with these guidelines have significantly improved survival. Despite the development and dissemination of BPG, their application in patients with ACS is suboptimal. This randomized control trial will use 2 groups: IVR and usual care. Patients in the IVR group will receive 5 automated calls at 1,3,6,9 and 12 months consisting of predetermined questions related to medication management, smoking cessation, diet, exercise and education as recommended by the ACC/AHA BPG for ACS. Responses are captured in a database allowing for interventions to maintain patients on BPG as needed.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: IVR group<br>Patients in this arm will receive IVR follow-up telephone calls at 1,3,6,9 and 12 months post-discharge consisting of predetermined questions related to medication management, smoking cessation, diet, exercise and education as recommended by the ACC/AHA BPG for ACS. Upon completion of the IVR follow-up, all patients will be called by a member of the clinical research staff and asked to complete a follow-up survey. | Other: IVR group<br>* Patients in this arm will receive IVR follow-up telephone calls at 1,3,6,9 and 12 months post-discharge consisting of predetermined questions related to medication management, smoking cessation, diet, exercise and education as recommended by the ACC/AHA BPG for ACS. Upon completion of the IVR follow-up, all patients will be called by a member of the clinical research staff and asked to complete a follow-up survey.<br>* Other names: Assignment to Interactive Voice Response;|
| No Intervention: Usual care<br>Patients in this arm will not receive IVR follow-up. One year after discharge, all patients will be called by a member of the clinical research staff and asked to complete a follow-up survey. | |
