Abstract

BACKGROUND

Improving medication safety implies patient-centred multidisciplinary cooperation. During the hospital stay for an acute care episode, the patient needs a comprehensive management to guarantee the best possible outcome.

METHODS

The study was designed as a non-blinded, multicentre stepped-wedge cluster randomised clinical trial, taking place in six French University Hospitals. Each cluster began with the control period in which standard care did not include pharmaceutical intervention. Every 14-day period, one hospital unit was electronically randomised to switch to the intervention period until all cluster groups received the intervention, which consisted of collaborative pharmaceutical care (CPC) associating medication reconciliation at hospital admission, pharmaceutical analysis of the medication order, medication review and collaborative meeting. The primary outcome was assessing the intervention through the rate of patients with at least one medication error (ME) on the admission medication order (such as omission, wrong dose or wrong route of administration), comparing the two periods.

RESULTS

CPC decreased the rate of patients with at least one ME from 88.9% (n = 243) to 29.2% (n = 267) (p < 0.0001). A total of 1817 MEs were discovered, of which 1121 (61.7%) were in the control period and 696 (38.3%) in the intervention period before resolution by the CPC. After resolving 567 of them, 129 medication errors still remained after CPC. So, a median of 3 MEs [IQR = 1;6] per patient were detected in the control period vs 0 [IQR = 0;1] after CPC in the intervention period (p < 0.0001). Patients were 21-times more likely to avoid a ME with CPC (OR: 20.8 [8.3;52.2], p < 0.0001). The rate of patients with a 2-3 critical ME level decreased from 70.8% to 12.0% in the control vs intervention periods respectively (OR: 18.4 [7.7;43.9], p < 0.0001).

CONCLUSIONS

CPC can prevent the occurrence of MEs and thus can improve inpatients' medication management and safety. Pharmacists play a key role in combating medication-related harm in healthcare settings.
