In the establishment, development, and provision of equal access to the health care system, the operation of adequate primary health care is essential and has undergone significant transformation in the most developed countries over the past decades. The central and eastern European countries, including Hungary, are struggling with the disadvantages of the traditional model of primary health care, based on independent general practitioner and family paediatrician practices: the ability of the system is extremely limited to meet emerging needs and is facing a chronic human resource crisis. In the current study, the functions, legislation, and challenges of the Hungarian primary health care system, as well as the basic interrelations of the development of vacant general practitioner and family paediatrician districts were examined, and the government measures for the sake of solving the occurrence of the vacancy and improving access in the lagging areas. (The situation of the other fields of primary health care-e.g., dental care, child care officer care, etc.-was not subject of the analysis.). The basic characteristics of the vacant districts (type by supplied age group, bounding region, population size, length of vacancy) were primarily examined by the analysis of categorical and metric variables, with the use of cross-tabulation and nonparametric correlation, while the discovery of soft interrelations was supported by an expert interview conducted with the professionals of the Primary Health Care Department of the National Health Care Services Centre. In Hungary, the fundamentals of primary health care are made up of the individual practices of general practitioners and paediatricians, and there is a growing concern about the permanent vacancy of the districts, and the fact that the system is less suitable for meeting the needs of the population. The ever-increasing number of vacant general practitioner and family paediatrician districts due to the growing shortage of professionals because of aging and emigration poses the burden of substitution on the physicians in existing practices, that concerns the access of more than a half million people to health care, almost 70 percent of which live in settlements with a population less than 5000 inhabitants.
