Evaluation of Pharmacist Medication Review Service in an Outpatient Heart Failure Clinic

Purpose: The purpose of this study was to evaluate the impact of pharmacist medication reviews on drug-related problems (DRPs) in a population with ambulatory heart failure (HF). Methods: The HF pharmacist medication review service incorporated a comprehensive medication review note provided to the cardiologist in a HF clinic. A retrospective chart review was performed on 64 control patients with no previous pharmacist review and 64 intervention patients who had a pharmacist medication review. The primary end point was the number of DRPs identified per patient in the intervention group 2 weeks after pharmacist medication review compared to the number of DRPs identified per patient in the control group. Results: The average DRPs per patient was reduced from 2.80 to 1.95 in intervention group after pharmacist intervention. There was a statistically significant difference between the average DRPs per patient in the control and intervention groups, 2.55 DRPs versus 1.95 DRPs per patient, respectively (P = .016). Medication adherence (78%), renal dosing (67%), hypertension (58%), and HF DRPs (55%) had the highest acceptance rate. The majority of DRP recommendations in the intervention (87%) and control groups (87%) were high-impact recommendations. Conclusions: Pharmacist medication reviews in an ambulatory HF clinic lead to significantly fewer DRPs.
