Abstract:

Background Current guidelines recommend use of sacubitril-valsartan in patients with heart failure with reduced ejection fraction (HFrEF). Early data suggested low uptake of sacubitril-valsartan, but contemporary data on real-world use and their associated cost are limited. Methods and Results This was a retrospective study of individuals enrolled in Optum Clinformatics, a national insurance claims data set from 2016 to 2018. We included all adult patients with HFrEF with 2 outpatient encounters or 1 inpatient encounter with an (), diagnosis of HFrEF and 6?months of continuous enrollment, also receiving ß-blockers and angiotensin-converting enzyme inhibitors/angiotensin receptor blockers within 6?months of HFrEF diagnosis. We included 70?245 patients with HFrEF, and 5217 patients (7.4%) received sacubitril-valsartan prescriptions. Patients receiving care through a cardiologist compared with a primary care physician alone were more likely to receive sacubitril-valsartan (odds ratio, 1.61 [95% CI, 1.52-1.71]). Monthly out-of-pocket (OOP) cost for sacubitril-valsartan, compared with angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, was higher for both commercially insured patients (mean, $69 versus $6.74) and Medicare Advantage (mean, $62 versus $2.52). For patients with commercial insurance, OOP cost was lower in 2016 than in 2018. For patients with Medicare Advantage, there was a significant geographic variation in the OOP costs across the country, ranging from $31 to $68 per month across different regions, holding all other patient-related factors constant. Conclusions Sacubitril-valsartan use was infrequent among patients with HFrEF. Patients receiving care with a cardiologist were more likely to receive sacubitril-valsartan. OOP costs remain high, potentially limiting use. Significant geographic variation in OOP costs, unexplained by patient factors, was noted.
