Importance: In 2015, the US Food and Drug Administration approved 2 new medications for treatment of heart failure with reduced ejection fraction, sacubitril/valsartan and ivabradine. However, few national data are available examining their contemporary use and associated costs. Objective: To evaluate national patterns of use of sacubitril/valsartan and ivabradine and associated therapeutic spending in Medicare Part D and Medicaid. Design, Setting, and Participants: In this US nationwide claims-based study, we analyzed data from the Medicare Part D Prescription Drug Event and Medicaid Utilization and Spending data sets to compare national patterns of use of sacubitril/valsartan and ivabradine between 2016 and 2017. Main Outcomes and Measures: Changes in total spending, per-beneficiary/claim spending, number of beneficiaries, and number of claims between 2016 and 2017 for sacubitril/valsartan and ivabradine. Results: The number of Medicare beneficiaries prescribed sacubitril/valsartan increased from 35423 to 90606 (156% increase from 2016 to 2017). Medicare beneficiaries prescribed ivabradine increased from 15856 to 23213 (46% increase). In 2017, Medicare Part D spent $227 million and $7.3 million on sacubitril/valsartan and ivabradine, respectively. This represented increases of 241% and 59% compared with 2016 spending, respectively. The annual Medicare per-beneficiary spending on sacubitril/valsartan and ivabradine was $2512 and $2400. Parallel trends in use patterns and spending were observed among Medicaid beneficiaries. Conclusions and Relevance: Although initial experiences suggested slow uptake after regulatory approval, these national data demonstrate an increase in use of sacubitril/valsartan and, to a lesser degree, ivabradine in the United States. Current annual per-beneficiary expenditures remain less than spending thresholds that have been reported to be cost-effective. Ongoing efforts are needed to promote high-value care while improving affordability and access to established and emerging heart failure therapies.
