Methods: We undertook a pragmatic, multinational, parallel arm prospective randomized open-label, blinded endpoint (PROBE) controlled trial enrolling patients at 6 European medical centers. We randomized 1537 older medical and surgical patients with multi-morbidity and polypharmacy on admission in a 1:1 ratio to SENATOR software-guided medication optimization plus standard care (intervention, n= 772, mean number of daily medications = 9.34) or standard care alone (control, n = 765, mean number of daily medications = 9.23) using block randomization stratified by site and admission type. Attending clinicians in the intervention arm received SENATOR-generated advice at a single time point with recommendations they could choose to adopt or not. The primary endpoint was occurrence of probable or certain ADRs within 14 days of randomization. Secondary endpoints were primary endpoint derivatives; tertiary endpoints included all-cause mortality, re-hospitalization, composite healthcare utilization and health-related quality of life.
Results: For the primary endpoint, there was no difference between the intervention and control groups [24.5% versus 24.8%; OR 0.98 (95% CI 0.77 to 1.24; p = 0.88]. Similarly, with secondary and tertiary endpoints, there were no significant differences. Among attending clinicians in the intervention group, implementation of SENATOR software-generated medication advice points was poor (approximately 15%).
Conclusions: In this trial, uptake of software-generated medication advice to minimize ADRs was poor and did not reduce ADR incidence during index hospitalization.
