Is sacubitril-valsartan more cost-effective than enalapril when started during hospitalization compared with 2 months after hospitalization for patients with heart failure with reduced ejection fraction?
In this economic evaluation, in a model of patients with heart failure with reduced ejection fraction, inpatient treatment with sacubitril-valsartan was associated with fewer admissions for heart failure and was cost saving in a budget analysis and from health care system and societal perspectives compared with initiation after hospitalization or no initiation.
The findings suggest that inpatient initiation of sacubitril-valsartan for patients with heart failure with reduced ejection fraction may be associated with reduced hospitalizations, increased quality-adjusted life expectancy, and cost savings compared with no initiation or initiation after hospitalization.
Sacubitril-valsartan use reduces mortality and hospitalizations compared with enalapril among patients with chronic heart failure with reduced ejection fraction (HFrEF); however, the cost-effectiveness of these treatments when initiated during hospitalization for HF is unknown.
To estimate the cost-effectiveness of inpatient initiation of sacubitril-valsartan vs enalapril compared with no initiation or posthospitalization initiation of sacubitril-valsartan among stabilized patients with HFrEF.
Design, Setting, and Participants
This economic evaluation included data on US patients with HFrEF who were eligible for sacubitril-valsartan treatment from December 8, 2009, to May 15, 2018.
Main Outcomes and Measures
A 5-state Markov model with all-cause mortality, HF, and non-HF hospitalization probabilities was used. Quality of life was estimated using Euro-QoL EQ-5D scores. Hospitalization, long-term care, and medication costs for sacubitril-valsartan and enalapril were modeled with a discount rate of 3%. The base-case analysis included a lifetime horizon from a health care and societal perspective.
Modeled patients were a mean (SD) age of 63.8 (11.5) years. Inpatient treatment with sacubitril-valsartan ($5628 per year) was associated with 62 fewer HF-related admissions per 1000 patients compared with outpatient initiation or 116 fewer HF-related admissions compared with continuation of enalapril treatment. From a health care system perspective, initiation of sacubitril-valsartan during hospitalization saved $452 per year compared with continuing enalapril and $811 per year compared with initiation at 2 months after hospitalization and was associated with an incremental cost-effectiveness ratio of $21 532 per quality-adjusted life-year compared with continued enalapril treatment over a lifetime. From a societal perspective, inpatient initiation was estimated to save $460 per year per patient compared with no initiation of sacubitril-valsartan and $813 per year per patient compared with initiation after hospitalization. In a budget analysis, inpatient initiation of sacubitril-valsartan was estimated to save up to $449 per person for 1 year or $2550 per person over 5 years compared with continuation of enalapril.
Conclusions and Relevance
The findings suggest that, for patients with HFrEF, initiation of sacubitril-valsartan during hospitalization may be associated with reduced hospitalizations, increased quality-adjusted life expectancy, and cost savings compared with no initiation or initiation after hospitalization.
