ABSTRACT
OBJECTIVE: To evaluate the cost-benefit of sacubitril/valsartan in adults with heart failure (HF) enrolled in a state Medicaid plan to prevent HF-related hospitalizations and emergency department (ED) visits. STUDY DESIGN: Retrospective, claims-based, cost-benefit study. METHODS: This exploratory cost-benefit study evaluated Massachusetts Medicaid (MassHealth) members with HF who had an initial pharmacy claim for sacubitril/valsartan between July 7, 2015, and August 31, 2018 (index date). Efficacy outcomes, HF-related hospitalizations and ED visits, and cost outcomes for HF-related medical and pharmacy claims were compared 1 year pre- and post index date. Benefit-cost ratio and net benefit were calculated for all members. A subgroup analysis evaluated the outcomes for members who were adherent to sacubitril/valsartan. RESULTS: A total of 22 members were identified for the study. There were fewer hospitalizations and ED visits post sacubitril/valsartan initiation in the overall population (post vs pre-: 23 vs 26) and among 12 members adherent to sacubitril/valsartan (10 vs 12). The median (IQR) cost for hospitalizations and ED visits was lower during the postindex period ($576 [$19,439] vs $132 [$11,692]) whereas the median (IQR) cost for HF pharmacotherapies was greater during the postindex period ($4578 [$3033] vs $270 [$255]). The benefit-cost ratio and net benefit were 0.91 and -$336, respectively, for all members and 1.43 and $2337, respectively, for members adherent to sacubitril/valsartan. CONCLUSIONS: The benefit as demonstrated by the cost avoidance of HF-related hospitalizations and ED visits did not outweigh the additional costs of sacubitril/valsartan, but cost-benefit was observed in members who were adherent to sacubitril/valsartan.
