The most common causes of accidents are traffic accidents, drowning, falls, poisoning, suffocation and, burns. Accidents vary depending on the age of the child. Aim of the study: The aim of this study was to show the circumstances and frequency of accidents in children treated in the Department of Intensive Care Pediatrics with postintensive care and how these indicators vary depending on demographic characteristics (age and sex of the child). Subjects and methods: The study was conducted as a retrospective cross-sectional study from 1 January 2009 to 31 December 2018 at the Clinic for Pediatrics, University Hospital Center Split. Data were collected by searching the written protocol and medical history of children aged 0 to 18 treated for injuries at the Department of Intensive Care Pediatrics with postintensive care. Results: The study included 352 children treated for accidents. The largest number of treated children were injured in traffic accidents (39%), as passengers in a vehicle (38%). Injuries are more common in boys (69%) than in girls (31%). 21% of the patients were tourists. (79%). Children belonging to the age group of 0 to 6 years were most often injured after a fall. The largest share of injured were children aged 13 to 18 (40%). Children in the age groups of 7 to 12 and 13 to 18 were most often injured in traffic accidents. The mortality rate was 3.7%. Conclusion: Injuries are an important cause of infant morbidity and mortality. They are most often the result of falls, in smaller children, and traffic accidents, in adolescence. Boys are more prone to injury than girls. Accident prevention in children is one of the priority tasks in improving and protecting children's health. Accidents and the consequences of accidents represent a great burden to modern society, so good and quality education of children and parents is extremely important in preventing accidents. Prevention includes health education of the general public, primarily parents, as well as all others who deal with children in their work. Education at the level of primary health care should be conducted by doctors of all specialties as well as community nurses, and begin with the earliest possible teaching of pregnant women and families about possible dangerous and harmful environmental impacts on the child. As a child grows, he or she should be involved in education. Secondary and tertiary levels of health care should also be included in prevention because they care for difficult and the most difficult patients and consequently have data on such patients, which gives their preventive recommendations of special importance.
