Introduction and research objectives: Introduction and aim of the research: Decompression sickness, also known as "divers' disease"," is a serious health risk based on Henry's law of gas solubility in body fluids under pressure. Symptoms range from mild to severe, and prompt diagnosis and treatment are essential for recovery. Prevention, which includes adherence to decompression protocols and diving techniques, is of paramount importance. Materials and methods: In this study, patients diagnosed with decompression sickness and treated at the Zadar General Hospital over an 11-year period were analyzed using data from the hospital's information system to examine sociodemographic characteristics and treatment outcomes. The analysis was based on descriptive statistics and statistical tests, focusing on the relationship between different variables. Ethical access was ensured through ethics committee approval. Results: During the eleven-year analysis period, 15 patients were included in the study of decompression sickness (DCS) at the General Hospital of Zadar. The majority of cases (66.67%) were patients aged 30 to 49 years, while a lower percentage was seen in younger and older patients. The majority of the sample consisted of men (73.33%). By year, the incidence of DCS was highest in 2016 and 2020, while in some years no cases were recorded. Most diagnoses were related to decompression sickness (86.67%), with rare cases related to barotrauma of the ear and other pressure effects. Conclusion: Research conducted by the Zadar General Hospital has shown that DCS is more common in divers aged 30 to 49 and in men than in people over 50. The fact that there were no deaths indicates the effectiveness of current treatment methods. The results highlight the importance of education and prevention to reduce the incidence of decompression sickness in divers and the need for further research to improve prevention and treatment methods.
