The paper covers basic aspects of private healthcare systems and focuses on the example of Croatia. Ten major special hospitals and polyclinics are analyzed in order to see the connection between their business activities and Croatia's EU entrance. Private healthcare is a healthcare system where services are paid directly for and not provided through insurance. The private health care sector facilities, in various nations across the globe, are a part of a significant and increasing industry that poses its problems and possibilities for nations working in the direction of universal coverage of health. (WHO, 2016) Many high income nations manage the private sector through a multitude of processes to regulate prices, quality, levels of service, and entitlement programs for people. Crucial legal problems for nations with high revenues include: the extent of interventionism needed to be adopted, options of systems of law and regulation, the role of different industries in controlling the provision of healthcare and the balance between distinct regulatory types. (WHO, 2016) Though the private provision is often widespread in low-income and middle-income nations, it is also relatively poorly controlled. Furthermore, in such nations, health system consumers face economic obstacles and the absence of social support. (WHO, 2016) Participants might be underreducated about their needs and therefore unable to assess most elements of quality and value. Hence they are susceptible to over-charging and maybe even quality reduction and expense escalation that could very well disqualify those who can afford it.
