Abstract 4135525: Bridging the Gap: How a Specialized Heart Failure Program Improves Guideline-Directed Medical Therapy Optimization for Rural Patients

Background: Previous research has shown that patients with heart failure with reduced ejection fraction (HFrEF) living in rural areas have suboptimal utilization of guideline-directed medical therapy (GDMT). Considering the associated increased mortality risk, this highlights the need for novel approaches to improve GDMT optimization for rural patients. The aim of this study was to evaluate how rural residence influences outcomes in a multidisciplinary, telehealth-based HF-GDMT optimization program implemented at our institution. Methods: We studied 322 patients who participated in a HF-GDMT optimization program led by a HF nurse practitioner and clinical pharmacist at Penn State Hershey Medical Center. We categorized residence at the time of enrollment using the Rural-Urban Commuting Area (RUCA) classification system. Differences in patient characteristics and program outcomes between the two groups were analyzed. P < 0.05 indicated statistical significance. Results: Among the 322 patients enrolled, 56 (17.4%) resided in rural areas and 266 (82.6%) in urban areas. Rural patients were younger (mean age 61.1 vs. 65.1; p=0.04) and the two groups differed significantly in racial demographics (p=0.006). The rural group had a higher proportion of patients with chronic HF (55.4% vs. 39.8%; p=0.038) and fewer patients with a recent HF hospitalization (30.4% vs. 49.2%; p=0.012). As far as outcomes, program completion rates were similar between rural and urban patients (83.9% vs. 83.1%; p=1). Those who received target doses of the four GDMT drug classes versus the maximum tolerated dose were also similar between the rural and urban groups (21.4% vs. 15.8%; p=0.32). Conclusions: Patients from rural areas were more likely to present with chronic HF and less likely to have recent HF hospitalizations compared to their urban counterparts, suggesting potential disparities in access to HF care. Despite these differences, program outcomes, measured by completion rates and GDMT medication titration, were comparable between the two groups. Our findings emphasize the crucial role of specialized HF programs in advancing GDMT use for rural patients, which may ultimately improve HF outcomes and bridge the healthcare gap.
