Abstract

Purpose: Interactive voice response (IVR) technology was used to increase medication compliance and reduce adverse events (hospitalization and emergency visits) in post-cardiac surgery patients.

Method: Patients randomized to intervention received 11 automated IVR calls in the six months after discharge. A total of 331 patients (164 IVR, 167 usual care) participated.

Results: Findings showed significant differences in the IVR group for the primary composite outcome of compliance and adverse events (relative risk (RR] and 95% confidence interval [CI]: 0.60 [0.37, 0.96), p = 0.041) and the secondary outcome of medication compliance (RR: 0.34 (0.20, 0.56), p < 0.0001). There was no significant impact on emergency room visits (RR: 1.04 (0.63, 1.73J) and hospitalization (RR: 0.77 [0.41, 1.45]). Most patients (93%) preferred IVR follow-up to no follow-up.
