Medication Discrepancies in Hospitalised Medical Patients - Status After a Decade With Targeted Medication Reconciliation Measures, a Cross-sectional Multicenter Study

Several targeted medication reconciliation (MR) initiatives have been introduced to reduce the number of medication discrepancies (MDs). The real-life quality of medication lists at hospital admission has however not been comprehensively investigated in the last decade. We aimed to examine the frequency and potential clinical relevance of MDs at hospital admission and investigate whether certain characteristics are associated with MDs. Patients >= 18 years old admitted to medical wards at 4 hospitals in Norway were included. MR was performed, and discrepancies between the reconciled medication list and the medication chart were identified. The potential clinical relevance was assessed in a short-term and long-term perspective. We included 250 patients and 201 (80%) had 1 or more MDs, mean 3.2 (SD 2.9) per patient. Out of 824 identified MDs, 171 (20.8%) and 362 (43.9%) were of moderate, major, or extreme potential clinical relevance in short- and long-term perspective, respectively. The risk of MDs increased with increasing age, increasing number of medications, and the use of multidose drug dispensing. Although several targeted MR initiatives have been launched, the frequency of MDs upon hospital admission is still high. However, the potential clinical relevance of the MDs seems less severe, which indicates an improvement.
