Abstract
Purpose
The DELIVER trial demonstrated the efficacy of dapagliflozin in reducing primary endpoint (cardiovascular (CV) mortality or worsening heart failure) for heart failure with mid-range ejection fraction (HFmrEF) and heart failure with preserved ejection fraction (HFpEF). This study assessed the economic and clinical effects of incorporating dapagliflozin into a standard treatment regimen for HFpEF and HFmrEF cases in China.
Methods
A multistate Markov model was used to assess the clinical and economic effects of adding dapagliflozin to the usual treatment regimen for HFpEF and HFmrEF. A log-logistic formula was used to represent the cumulative incidence of hospitalization, readmission, and CV mortality. A 5% annual discount was applied to all costs. The health outcome was the incremental cost-effectiveness ratio (ICER), measured using quality-adjusted life years (QALYs) and life years (LYs). The findings were examined using sensitivity and scenario analyses to assess robustness.
Results
In the HFpEF or HFmrEF population, the 11.2-year incremental QALYs was 0.15 and LYs was 0.2, yielding an ICER of $10,615.87 per QALY and $7,763.08 per LY. These ICER values are lower than China’s per capita gross domestic product (GDP) of $12,752 in 2022. The one-way sensitivity analysis revealed that non-hospital CV death was the most influential parameter. Furthermore, there was a 68% chance that dapagliflozin was cost-effective as an additional treatment, given a willingness-to-pay limit of three times the GDP ($38,256).
Conclusions
Dapagliflozin adjunctive therapy was cost-effective in patients with HFpEF or HFmrEF from the perspective of Chinese national insurance.
