OBJECTIVES: In 1993 a Diagnosis Related Groups-like financing system was introduced in Hungary including all the Hungarian acute care hospitals. The aim of the study is to analyse the market share of addictology, the capacity and performance data of addictology according to the progressivity levels and Diagnosis Related Groups (DRGs) in Hungary. METHODS: The data derive from the financial database of the National Health Insurance Fund Administration of Hungary for the year 2015. The study includes the analysis of the number of hospital beds, the DRG weights, the financial cases and average lenght of stay. RESULTS: Addictology care was available in 11 Hungarian hospital in 2015. It means that among the 20 counties in Hungary, in 9 county addictology services are not available. The market share of addictology in in-patients care was 0.5 % from acute care hospital beds and 0.16 % from the total DRG cost-weights. The market share of addictology from financial cases was 0.19% and 0.43 % from total hospital days. The average length of stay of patients admitted to addictology wards was 12.3 days/patient, sginificantly higher than the average of all acute care specialty (5.3 days). CONCLUSIONS: Hungarian patients have limited access to acute addictology services. In 9 counties out f 20 addictology services are not available. In order to improve patients’ access to addictology care, its market share should be increased.
