BUDGET IMPACT MODELLING
A budget impact model (BIM) is a means to assess the affordability of a therapy. An important input is the determination of a country-specific eligible patient population. Increasingly, a BIM analysis is an essential part of a comprehensive economic assessment of a health care technology. Although it is increasingly required by payers prior to approval or for reimbursement, no formal guidance on conduct and reporting of budgetary impact analyses is provided.
