Budget Impact Analysis (BIA) Services
Cost-effectiveness tells a payer whether an intervention is good value. A budget impact analysis tells them whether they can afford it. The two answer different questions, and most reimbursement decisions need both. EvySaif builds clear, payer-ready budget impact models that project the financial consequences of adopting a new treatment over a defined time horizon.
- Affordability over a realistic horizon
A budget impact analysis estimates the change in total spending when a new intervention enters a defined population, usually over a one to five year horizon. We build models that account for the size and growth of the eligible population, current and projected treatment mix, drug and administration costs, and the downstream costs avoided or added. Built to ISPOR good-practice principles, the model lets a payer see the year-by-year financial picture and test it against their own assumptions, which is exactly what a formulary or reimbursement committee needs to make a decision.
- What we deliver
- Budget impact models with a one to five year horizon
- Eligible-population sizing using epidemiology and market-share inputs
- Scenario and one-way sensitivity analysis on the key drivers
- Interactive payer-facing models where required, with adjustable inputs
- Local adaptation to India and Middle East cost and population settings
- Clear technical report and summary suitable for payer and committee review
- Who it is for
Manufacturers preparing payer submissions, market access teams building reimbursement dossiers, and health systems forecasting the cost of adopting a new technology.
- Why EvySaif
As one of the best research and medical writing consultancies in India, EvySaif pairs clinical depth with regulatory rigour. We build budget impact models that are transparent and adjustable, so a payer can stress-test them rather than take a black box on trust. The clinical and epidemiological assumptions are clinician-reviewed, the structure follows ISPOR good practice, and the model is paired naturally with the cost-effectiveness work when a submission needs both. For Gulf and Indian payers, we adapt the cost and population inputs to the local market.
- Frequently asked questions
How is a budget impact analysis different from a cost-effectiveness analysis?
A cost-effectiveness analysis measures value (cost per unit of health gained). A budget impact analysis measures affordability (the total change in spending). Payers typically want both.
What time horizon do you use?
Usually one to five years, matched to the payer's planning cycle, since budget impact is about near-term affordability rather than lifetime value.
Can the model be interactive?
Yes. We can build payer-facing models with adjustable inputs so stakeholders can run their own scenarios.
