Education and training for major incidents and disasters started in Croatia 20 years ago during the Homeland War, 1991-1995. In the beginning of the war in Croatia, all medical institutions were receiving orders and instructions for crisis preparation from the Crisis Headquarters of the Ministry of Health. The integrated health system had been established in which civilian and military systems were mutual. Proper planning and preparedness resulted in excellent medical care performed by civilian and military organizations; 20 years later we started education and training in Croatia based on Medical Response to Major Incidents courses.
