OBJECTIVES: In 2012 the Hungarian intensive care units system was restructured. The multidiscipline intensive care units were separated from the postoperative intensive units and the one specialty intensive units. The effect of it was analyzed. METHODS: Data were got from the National Health Insurance Fund Administration of the intensive care units for 10 years. There were investigated the organizational and the patient care related data. RESULTS: In 2012 the number of the multidiscipline intensive care units decreased 20% and the number of beds decreased 10%.  Due to reorganization both the CMI and days of mechanical ventilation increased significantly in the multidiscipline intensive care units. In 2000 the 12% of the patients were discharged from the intensive care units to home, but by 2014 this rate decreased to 3%.  It showed the use of the intensive care units were partially unnecessary before the reorganization. If we take the optimal bed-usage for the intensive care units to be 85%, in the new situation the actually available reimbursement approached to the theoretical value. The average bed-usage was 55% in the both period, but the statistical variance between the separated intensive care units decreased in the last years. CONCLUSIONS: The results shows that the reorganization was effective.  Level of the intensive care have got higher, the use of the beds and the reimbursement increased. It is suggested to do similar reorganizations in the other specialties.
