SA10 Benchmarking of Budget Impact Results: An Updated Systematic Review of US Budget Impact Analyses

Abstract

To inform drug formulary decision-making, US reimbursement authorities commonly require budget impact analyses (BIA), typically reported as budget impact (BI) per member per month (PMPM). However, proper interpretation of BI PMPM is hampered by the lack of accepted pre-specified PMPM thresholds defining a financially acceptable BI. We updated a prior systematic review of published US BIA to establish PMPM benchmarks and assess how BIA authors qualitatively interpreted their own results.
