Identifying racial disparities in the management of heart failure with reduced ejection fraction

Abstract

Objective(s): Heart failure (HF) is chronic and progressive. Individuals with a left ventricular ejection fraction (LVEF or EF) < 40% are classified as having heart failure with reduced ejection fraction (HFrEF). Black patients have the highest incidence of HF and are more likely to suffer serious consequences from the disease. Identifying and addressing racial disparities in care is vital to ensuring health equity. The primary objective was to determine the association of race with 1-year heart HF admission rates for white and black patients, when adjusted for EF and age. The secondary objective was to determine the proportion of patients not on guideline-directed medication therapy (GDMT).

Design: This study was a retrospective chart review conducted between 10/22/2021 and 11/22/2022 of Veteran patients with HFrEF who were identified via the VA Heart Failure Dashboard. Only White and Black patients were included. A multivariable logistic regression was used to determine odds of admission due to HF. Pharmacotherapy was analyzed to identify gaps in GDMT and if racial disparities existed.

Setting and participants: Veterans within the Veterans Affairs Western New York Healthcare System.

Outcome measures: One-year HF admission rates for white and black patients, when adjusted for EF and age. Proportion of patients not on GDMT.

Results: Of the 345 patients with HF originally identified, 172 were included; 22% were admitted within one year. Black patients were 2.9 times more likely to be admitted. (P = 0.031). A median of two drugs (interquartile range [IQR] 1-3) could be added and one dose could be optimized (IQR 1-4) to reach GDMT goals. No differences were found in the prescribing of GDMT or in proportion of patients not on GDMT at recommended doses between white and black patients.

Conclusion: Black patients were more likely to be admitted for HF than white patients. Pharmacists can play an important role in identifying the need for optimizing GDMT. Future studies could focus on pharmacist-led prospective interventions with an aim to close the gap in racial disparities.
