The aim of research was to investigate the success of the civil - military integrated health care in the casualties of civilians and armed forces during Patriotic war in Croatia in time from 1991 to 1995. For purposes of this research a questionnaire was made containing approximately 150 parameters and is shown in the appendix. The study was conducted on a randomly chosen sample of 5000 subjects of whom 74.1 percent were members of the armed forces, and 25.9 percent of civilians. Most were men, 93.3 percent. Most casualties were in the open space 86,0 percent, 81.1 percent of armed forces on the battlefield and civilians 72.8 percent in the place of residence. Descriptive statistic was applied to describe the data, and hypotheses are tested parametric (ANOVA) and nonparametric (x - test, Mann - Whitney test) methods. Assessment of the subjects, groups of armed forces and civilians, depending on a number of predictors was performed by logistic regression model. The most common causes of death and civilians and forces were the effects of artillery weapons. From the organ systems, most have suffered skeletal (33.2 percent) and muscular (29.8 percent), and the anatomical region of the lower extremities (36.6 percent), upper extremities (29.2 percent) and head and neck (23.8 percent). First aid as at civilians (96,0 percent) and as at forces (88.3 percent) was most frequently offered by medical teams. For civilians in the first hour help was given (71.2 percent) while in the forces (63.1 percent). The length of hospital stay was similar for civilians and members of the armed forces. In about 50,0 percent of cases it was up to 7 days, about 70,0 percent of cases it amounted to 14 days. The result of treatment was slightly better in the category of civilians where the outcome of treatments entered - "cured" (16.3 percent), and forces, 12.5 percent. Equal percentage (60,0 percent) and civilians and forces was released or transferred to other institutions with "improved" health condition. Hospital mortality as an outcome of treatment varies considerably between civilians and forces. For the category of civilians amounted to 4,0 percent, and for members of the armed forces (1, 9 percent) or an average of 2.4 percent in both groups. Comparison of the results of this work with data from the U.S., Great Britain, Israel, SSSR (Russia), Serbia and Bosnia and Herzegovina, and refer to the Vietnam War, Falklands War, the Israeli - Arab wars, the Soviet - Afghan war, modern wars leading by the U.S., NATO and its allies in Iraq and Afghanistan, and the wars in former Yugoslavia, came to the conclusion that the integrated military-civilian approach in the treatment of casualties was equally successful as the approach of large countries, but by the use of manpower and material resources was more economical.
