What is a Budget Impact Analysis (BIA) and its purpose?

• A. An assessment of the financial impact of adopting a new intervention on a specific budget over time from the payer perspective.
• B. An assessment of the biological mechanism of intervention.
• C. An assessment of patient satisfaction.
• D. An assessment of global economic impact.

Answer: (A)

A Budget Impact Analysis looks at the financial consequences of adopting a new health intervention for a specific payer’s budget over a defined period. It focuses on affordability from the payer or budget holder’s perspective, not on clinical effectiveness. It lays out how much the intervention would cost, how it might shift costs from current practice, and any potential offsets from changes in resource use, given assumed uptake, price, and eligible population. The horizon is typically short to mid-term (for example, 1–5 years), and the results are presented as total net budget impact and per-member costs to help decision makers plan and allocate resources. This is different from assessments of biological mechanism, patient satisfaction, or global economic impact, which lie outside the payer-focused budgeting scope.
