OBJECTIVES:  Healthcare decision-makers are increasingly using Budget Impact Models (BIMs) to evaluate the financial impact of adopting a new health technology. The requirements of BIMs vary by market, and the current BIM development strategy employed by global Health Economics teams do not always meet specific local requirements. The objective of this research was to understand the different requirements of BIMs at the local level, and to develop a method of creating a global BIM that is easily adaptable and/or usable by local markets. METHODS:  A four-step approach was taken: 1) countries that currently adopt HTA process (formal or informal) were identified in Europe, America, Asia-Pacific, and the Middle East; 2) a literature search was conducted to identify the budget impact requirements of different HTA bodies; 3) initial recommendations were outlined, and tested with external stakeholders; and 4) final recommendations were developed. RESULTS:  23 countries were identified that adopt HTA process; all of these were found to require some form of budget impact analysis. The requirements of the BIMs could be categorised into three groups, based on complexity. Our initial recommendation was to develop a global BIM that incorporates three components: 1) a simple cost analysis of the new health technology; 2) an additional module to include a range of comparators, resource use and healthcare costs; and 3) a cost sequence analysis with selected health outcomes derived from clinical trials. A global BIM should incorporate all three components that can be customised by local markets. This recommendation has been validated by local HTA experts. CONCLUSIONS:  In order to make a global BIM more suitable for local use, it should be developed in a modular fashion where local markets can choose which module(s) to adopt.
