Improvement of Guideline Beta-Blocker Prescribing in Heart Failure: A Cluster-Randomized Pragmatic Trial of a Pharmacy Intervention

Abstract

Treatment with specific beta-blockers and doses recommended by guidelines is often not achieved in practice. We evaluated an intervention directed to the pharmacy to improve prescribing.We conducted a pragmatic cluster-randomized trial, where facilities (n = 12) with patients (n = 220) were the clusters. Eligible patients had a beta-blocker prescription that was not guideline concordant. Level 1 intervention included information to a pharmacist on facility guideline concordance. Level 2 also provided a list of patients not meeting guideline goals. Intervention and follow-up periods were each 6 months. Achievement of full concordance with recommendations was low (4%-5%) in both groups, primarily due to lack of tolerability. However, compared with level 1, the level 2 intervention was associated with 1.9-fold greater odds of improvement in prescribing (95% confidence interval [CI] 1.1-3.2). Level 2 patients also had greater odds of a higher dose (1.9, 95% CI 1.1-3.3). The intervention was aided by the patient lists provided, the electronic medical record system, and staff support.In actual practice, full achievement of guideline goals was low. However, a simple intervention targeting pharmacy moved patients toward guideline goals. As health care systems incorporate electronic medical records, this intervention should have broader feasibility.
