Healthcare utilization and guideline-directed medical therapy in heart failure patients with reduced ejection fraction.

Aim: This study examines the effect of guideline-directed medical therapy (GDMT) on healthcare utilization in patients with heart failure with reduced ejection fraction from Optum® Integrated File from 1 January 2007 to 30 June 2020. Materials & methods: Patients with both a beta blocker and either an ACE inhibitor (ACE-I), angiotensin receptor blocker (ARB) or angiotensin receptor neprilysin inhibitor were assigned to the GDMT cohort. All others were not on GDMT. Results: Estimated annual all cause hospitalizations and emergency department visits per 100 patients was 29% (80 vs 62 patients) and 26% higher (54 vs 43 patients; p < 0.0001) and annualized hospital days were longer (1.88 vs 1.64; p = 0.0020) for patients not on GDMT. Conclusion: In a real-world population, heart failure with reduced ejection fraction, patients not optimally managed on GDMT had higher annualized healthcare utilization when compared with patients on GDMT.
