BACKGROUND: Although medication reconciliation (MedRec) is effective in decreasing medication discrepancies, the effectiveness on Adverse Events (AEs) is very scarce. The objective of this study was to assess the effect of MedRec by a pharmacy team on patient-reported, potential AEs post-discharge. METHODS: This was a multicenter prospective intervention study with before-after design at two Dutch hospitals. Participants were patients aged ≥18 years admitted for more than 48 h using three or more prescription medications upon discharge. Patients in the control group received usual care. In the intervention period, a trained team of pharmacy staff executed medication reconciliation consisting of patient education upon admission and discharge, review of prescribed medication to identify errors, and information transfer to primary care. To address the primary outcome, the difference in proportion of patients with one or more potential AEs was measured by a structured telephone interview, two weeks after discharge between usual care and intervention group. To address the second outcome, the difference in median number of potential AEs per patient was calculated. Other outcomes assessed included the association between the intervention and patient characteristics. RESULTS: In total, 221 (138 usual care and 83 intervention) patients were included. The proportion of control and intervention patients with AEs was 88.4% and 86.7% respectively (p > 0.05). The median number of potential AEs per patient was lower in the intervention group compared with usual care (1.1 vs. 2.1, p < 0.0001). Being in the intervention arm was associated with less potential AEs (RR 0.5, 95% CI [0.4-0.6]), whereas being previously admitted was associated with a higher number of potential AEs (RR 1.3, 95% CI [1.1-1.5]). The effect of the intervention on the number of potential AE was stronger among women compared with men (p = 0.04). CONCLUSION: Although the intervention did not decrease the proportion of patients with AEs, a significant reduction in the median number of potential AEs after hospital discharge between the intervention and usual care group was observed.
