Using interactive voice response to improve disease management and compliance with acute coronary syndrome best practice guidelines: A randomized controlled trial.

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.
