Success in Heart Failure? An Investigation of Heart Failure Readmission Rates and Medication Regimen Optimization

Abstract

In May 2022, the American College of Cardiology updated their guideline-directed medical therapy for congestive heart failure (CHF) to include four pillars of therapy. These pillars aim to better control patients with heart failure (HF) and reduce the incidence of hospitalization by including an evidence-based beta-blocker, an angiotensin-converting enzyme inhibitor/ angiotensin receptor blocker/angiotensin receptor/ neprilysin inhibitor, a mineralocorticoid receptor antagonist, and newly recommended sodium glucose cotransporter 2-inhibitors. This study at University of Florida Health Central Florida Hospitals reviewed patients who were diagnosed with CHF and recorded if they were readmitted with a HF exacerbation within 30 days of an initial index admission. Patients had data obtained retrospectively using electronic medical records from patient hospital encounters within the study inclusion dates; 7/1/2022-9/30/2022. Hospital readmission rates for patients with CHF, and information on each patient’s medication regimen was collected to see if they met medication optimization criteria. A total of 252 patients were evaluated, with 157 meeting the inclusion criteria. Of the patients included, 23 (14.6%) experienced a hospital readmission within 30 days because of acute HF exacerbation or worsening HF. After reviewing medication regimens, 60 patients (38.2%) were receiving treatment with one pillar of therapy, 72 (45.8%) with two pillars of therapy, 12 (7.6%) with three pillars of therapy, and one patient was treated with all four pillars of therapy. In conclusion, this study showed that the recommended pillars of therapy are not being implemented and patients with CHF may benefit from medication optimization.
