A cost-effectiveness analysis of empagliflozin for heart failure patients across the full spectrum of ejection fraction in Spain: combined results of the EMPEROR-Preserved and EMPEROR-Reduced trials

Abstract

ABSTRACT Background Heart failure (HF) is a chronic condition with considerable clinical burden for patients and economic burden for healthcare systems. Treatment for HF is typically based on ejection fraction (EF) phenotype. The cost-effectiveness of empagliflozin + standard of care (SoC) compared to SoC has been examined for HF phenotypes below or above 40% EF separately, but not across the full spectrum of EF in Spain. Methods The results of two preexisting, validated, and published phenotype-specific Markov cohort models were combined using a population-weighted approach, reflecting the incidence of each phenotype in the total HF population in Spain. A probabilistic sensitivity analysis was performed by sampling each model’s probabilistic results. Results Empagliflozin + SoC compared to SoC resulted in increased life-years (LYs) (6.48 vs. 6.35), quality-adjusted LYs (QALYs) (4.80 vs. 4.63), and healthcare costs (€19,090 vs. €18,246), over a lifetime time horizon for the combined HF population in Spain. The incremental cost-effectiveness ratio (ICER) was €5,089/QALY. All subgroup, scenario, and probabilistic ICERs were consistently below €10,000/QALY. Conclusions Empagliflozin is the first treatment with established efficacy and cost-effectiveness for HF patients across EF from the perspective of healthcare payers in Spain. Empagliflozin also proved to be cost-effective for all subgroups of patients included in the analysis.
