Background: Medication errors continue to exist despite the use of electronic health records and electronic prescribing; patient-centered medication reconciliation is important to decrease errors.
Objective: To identify whether a team-based approach with a pharmacist performing medication management and discharge medication reconciliation will reduce discharge-related medication errors in an academic tertiary care hospital already using an electronic health record and computerized physician order entry.
Design: Prospective nonrandomized controlled trial.
Patients: All patients were admitted to 2 of the 6 medicine teams from August 1, 2012, through October 31, 2012.
Intervention: On the intervention team, a pharmacist assisted with medication management, medication reconciliation, and medication education upon discharge. Although the physicians on the control team had access to a pharmacist, they rarely collaborated with the pharmacist. The numbers of discharge-related medication discrepancies on the intervention and control teams were compared.
Results: Collaboration with a pharmacist reduced discharge-related medication errors. The percentage of patients without medication errors within 72 hours of discharge was 93.8% on the intervention team compared with 40.2% on the control team (P < .0001).
Conclusion: Pharmacist's involvement in the patient care team improved patient safety by decreasing discharge medication errors caused by using electronic health records and computerized physician order entry.
