"Background: The National Supplementary Health Agency (ANS) regulates Brazil's private health insurance sector, which covers approximately 26.3% of the population. Health insurance providers must cover a minimal range of medicines, devices, and medical procedures. This minimal list of services is subject to constant updating in response to submissions, which must include a budget impact analysis. Then, ANS and its collaborators critically examine the proposals, usually reproducing budget impact evaluations and optimising assumptions about population size, costs, and frequencies, among other factors.
Objectives: Description of the implementation and validation of a user-friendly budget impact analysis spreadsheet considering ANS perspective.
Methods and expected results: Health technology assessment experts will create and validate the spreadsheet, incorporating the assumptions of the Brazilian Ministry of Health's Budgetary Impact Methodological Guideline regarding the eligible population, market share, costs, cohorts, population migration in time and sensitivity analyses. The spreadsheet will assist in critically appraising proposals for medicines, medical devices, and surgical and therapeutic techniques for different medical conditions. Results include the spreadsheet along with a practical workshop and guidance document.
Conclusions: By enhancing and simplifying the budget impact evaluation spreadsheet, we intend to strengthen the critical evaluation of proposals for the ANS list, assisting decision-makers and private health insurance beneficiaries in Brazil."
