Parallel Group Randomized Controlled Trial to Assess the Impact of Medication Reconciliation at Hospital Admission on Healthcare Outcomes

Medication reconciliation is a systematic process by which health care professionals obtain the most complete and accurate information about the drugs regularly taken by patients. Internationally, the value of this procedure is mainly attributed to the reduction in the number of adverse drug events, which can cause drug-related morbidity and mortality, as well as unnecessary health care costs.

As part of the Progress! Pilot project Safe Pharmacotherapy at the interface points, promoted by the Federal Office of Public Health, coordinated by the Swiss Patients Safety Foundation and held in several Swiss hospitals, medication reconciliation at hospital admission was introduced at the regional hospital Beata Vergine in Mendrisio, from 2014 to 2016. During this pilot project it was shown that medication reconciliation after obtaining the best possible medication history by a pharmacist at hospital admission, in comparison with the standard medication history obtained by the physician at admission, reduced the number of clinically relevant drug discrepancies.

A structured, well-established and practicable procedure of medication reconciliation that improves patient safety assuring a better quality of care at hospital admission might provide evidence that medication reconciliation could be a valuable intervention to be applied systematically in all EOC hospitals at admission, as well as subsequently potentially at the other hospital interfaces.

The purpose of this study is to evaluate whether obtaining the best possible medication history and performing medication reconciliation at hospital admission results in improving some specific healthcare outcomes.

The study seeks primarily to determine if obtaining the best possible medication history and performing medication reconciliation, in comparison with the standard medication history, reduces the number of subsequent unplanned all-cause hospital visits (readmissions and emergency department visits within 30 days after initial discharge). As secondary objectives, the study aims at assessing if best possible medication history with medication reconciliation, in comparison with the standard medication history, reduces the incidence of adverse drug reactions during hospital stay, shortens length of stay, leads to a reduction in the use of hospital resources, and/or is associated with a decreased number of deaths.
