Effect of an Electronic Medication Reconciliation Intervention on Adverse Drug Events
A Cluster Randomized Trial (Robyn Tamblyn, MSc, PhD, FCAHS, CM; Michal Abrahamowicz, PhD; David L. Buckeridge, MD, PhD; et al)
Adverse drug events (ADEs) account for up to 16% of emergency department (ED) visits and 7% of hospital admissions. Medication reconciliation is required for hospital accreditation because it can reduce medication discrepancies, but there is no evidence that reducing discrepancies reduces ADEs or other adverse outcomes.
Electronic medication reconciliation reduced medication discrepancies but did not reduce ADEs or other adverse outcomes. Hospital accreditation should focus on interventions that reduce the risk of adverse events for patients with multiple changes to community medications.
