Hospitalization is associated with a higher risk of medication errors [1]. Indeed, many of the patient's usual prescriptions may be modified on admission, during the hospital stay itself, and/or on discharge [2]. These modifications concern up to 70% of patients and may account for more than half of the adverse drug events (ADEs) that occur in hospital or after discharge [3,4]. To reduce medication errors at care transitions, medication reconciliation (MR) was developed in the early 2000s. In a systematic, comprehensive review of all the medications a patient is taking, an accurate and comprehensive medication information is communicated consistently across care transitions [5].
