Cost Effectiveness of Adding Dapagliflozin to Standard Care in Heart Failure Patients with Reduced Ejection Fraction: A Systematic Review.

INTRODUCTION: Dapagliflozin, a new treatment option for heart failure, leads to a significant reduction in the hospitalization of patients with heart failure. We aimed to review studies on the economic evaluation of adding dapagliflozin to standard care compared with standard care alone in heart failure patients with reduced ejection fraction (HFrEF). METHODS: For this systematic review, the PubMed, EMBASE, Web of Science, Cochrane, Scopus, and CEA Registry scientific databases were searched from 1 January 2020 to 25 March 2022. Two of the present researchers screened titles and abstracts, extracted data from full-text articles, and evaluated their quality using the Quality of Health Economic Studies (QHES) checklist for the quality assessment of health economic studies. RESULTS: Of the 456 abstracts screened, 19 studies met the inclusion criteria. The mean QHES score for the studies was 0.87 (high quality). Eight studies on cost-effectiveness analysis, ten studies on cost-utility analysis, and one study on cost-minimization analysis were conducted. Based on the available evidence and the present findings, the addition of dapagliflozin to standard care in patients with HFrEF was cost effective in most countries. CONCLUSIONS: Based on the results of the present study, the addition of dapagliflozin to standard care in patients with HFrEF was cost effective. More studies investigating the cost effectiveness of dapagliflozin in patients with HFrEF are required in light of the actual epidemiological data of countries in the relevant input parameters. It is also recommended to conduct cost-effectiveness studies of dapagliflozin taking into account costs and benefits from a societal perspective.
