Abstract 15483: A Clinic-based Intervention Achieves Target Doses of Guideline-directed Medical Therapy in Heart Failure

Abstract

Introduction: Target doses of guideline-directed medical therapy (GDMT) reduce morbidity and mortality, and yet, are challenging to achieve in patients with heart failure and reduced ejection fraction (HFrEF). Long-term, relationship-based approaches are not well described. Methods: We implemented a person-centered approach in a nurse-managed multidisciplinary heart failure clinic. We used repeated measures analysis to prospectively evaluate patient satisfaction, appointment attendance, dose optimization of GDMT for renin-angiotensin inhibitors, beta-blockers (BB), mineralocorticoid antagonists (MRA), and anticoagulation, and ICD placement and cardiac rehab participation at 12 months. GDMT was scored 0-6, with one point for each guideline-indicated therapy. Composite scores were compared using ANOVA at baseline, 6-months, and 12-months. Results: Participants (n=102) were age 68 (± 14.95) years on average, predominantly white (95.1%), male (62.75%), and high school graduates (88.24%). At 12-months, the proportion of patients on ≥50% of target doses improved: renin-antiotensin inhibitors from 27% to 41%, beta-blockers from 46% to 64%, and MRA from 35% to 65%. Cardiac rehab attendance improved from 25% to 84%. Patient satisfaction with care improved; four (3.9%) patients did not attend scheduled follow-up in the 12-month period. Though overall composite scores of GDMT improved (F=51.74, p <0.001), only 12% of patients achieved target doses for all 3 medication classes concomitantly. No participants were readmitted within 30 days of HF-hospitalization; all-cause 30-day readmission was 10.5%. Conclusion: A persistent patient-provider relationship and person-centered approach to HF management may improve GDMT.
