Evaluation of Pharmacy Resident-Driven Medication Reconciliation on Patients at High Risk of Hospital Readmission.

Pharmacists play a key role in preventing medication errors during transitions of care and preventing hospital readmissions through medication reconciliation (MR) programs. This study retrospectively evaluated the implementation of a standardized pharmacy residentdriven MR program for patients at high risk for readmission as defined by the Hospital Readmissions Reduction Program (HRRP). This was a single-center, retrospective cross sectional study of a pharmacy resident-driven MR program including patients at high risk of readmission defined by HRRP. The primary objective was to determine the number of inpatient regimen interventions identified during the MR. Secondary objectives include severity of interventions, number of medication discrepancies identified, types of interventions and discrepancies identified, and all-cause hospital readmission rates within 30 days of discharge.. Fifty-three high-risk patients were included in the study. Pharmacy intervention recommendations were accepted by prescribers for nine patients (9/53; 17.0%) with a total of 13 accepted inpatient regimen interventions. The two most commonly identified medication classes for interventions were anticonvulsants (3/13; 23.1%) and antidepressants (6/13; 46.2%). Discrepancies on the admission MR were identified for 46 (46/53; 86.8%) patients with a median of three discrepancies per patient (interquartile range 2-4). The most common type of discrepancy was an incorrect or unnecessary drug. The 30-day all-cause readmission rate was 35.8% (19/53) for the total patient A pharmacy-resident driven MR program provided value in clarifying prior to admission medications and may help prevent drugrelated adverse events.
