Using interactive voice response to improve disease management and compliance with acute coronary syndrome best
Background:
There is evidence from large clinical trials that compliance with standardized best practice guidelines (BPGs) improves survival of acute coronary syndrome (ACS) patients. However, their application is often suboptimal.
Purpose:
In this study, the researchers evaluated whether the use of an interactive voice response (IVR) follow-up system improved ACS BPG compliance.
Method:
This was a single-centre randomized control trial (RCT) of 1,608 patients (IVR=803; usual care=805). The IVR group received five automated calls in 12 months. The primary composite outcome was increased medication compliance and decreased adverse events.
Results:
A significant improvement of 60% in the IVR group for the primary composite outcome was found (RR 1.60, 95% CI: 1.29 to 2.00, p <0.001). There was significant improvement in medication compliance (p <0.001) and decrease in unplanned medical visits (p = 0.023). At one year, the majority of patients ( 85%) responded positively to using the system again. Follow-up by IVR produced positive outcomes in ACS patients.
