This paper presents the possibility of applying business intelligence in the creation of public health and financial policies. Theoretical part of the work describes the development of business intelligence over time, gives an overview of the definitions of business intelligence, and individually explained the preconditions and components of business intelligence. Health system in the Republic of Croatia is described from the aspect of organization and financing. In the empirical part of the work, the research was focused on examining the causes and consequences of the difference in the number of insured persons and the number of inhabitants in order to use the results to help create public policies related to savings in healthcare. The free Microsoft Power BI tool was used for data analysis and visualization, and the results showed that in the entire Republic of Croatia there is a difference in the number of insured persons and the number of inhabitants, which is greater in counties with greater external population migration. By applying business intelligence tools, it is possible to identify parameters important for the creation of public health-financial policies and, based on the number of external migrations and the number of visits to family doctors, to determine savings in public health financing for various primary health care.
