Medication reconciliation is an important care process anytime a patient transitions from one care setting to another, including emergency department to hospital admission. This study sought to determine the incidence of completed medication reconciliation for admitted trauma patients and the number of identified discrepancies. Of the 89 patients included in the study, more than a quarter did not receive an admission medication reconciliation (AMR), and of those with an AMR, 48% had at least one unintended discrepancy, indicating the importance of completing medication reconciliation for all admitted trauma patients.
