The problem of this paper is the financing of health care in the Republic of Croatia. As healthcare has become the leading industry of new technologies in the world, it is necessary to constantly invest in it. The modern age is characterized by the development of information technologies that are applied in the field of health, which makes it more efficient and high quality. In order to exist at all, but also to increase efficiency, the health system must be financed from some sources. No health system in the world can provide enough funding, but at least it can strive for as many of those resources as possible. From this paper it can be concluded that the health care of the Republic of Croatia is financed from many different sources, but not efficiently enough, which is why an illiquid system appears. Namely, the Republic of Croatia is characterized by a shortage of doctors and overpriced medicines, which is why a poor health care system is emerging. If it continues in the same direction, it is very likely that in the future this system will be even less efficient and of poor quality. Therefore, it is necessary to introduce new measures and find new sources of funding or "strengthen" these existing ones.
