Chronic wounds which include pressure ulcers, vascular, inflammatory, and rheumatologic subtypes affect more than 6 million people, with an expected increasing number in a ever-increasing elderly and diabetic population, and thus represent an extreme public health problem. Chronic wounds are linked with significant mortality and morbidity and present themselves as significant medical costs. Prevention and treatment of chronic wounds is correlated with disease-specific approach towards the wound and the use of moisture-retaining dressings and supportive topical therapies which promote closing of the wound. One of the most important procedures in the treatment of chronic wounds is the application of modern supportive dressings. The choice of dressings depends on a large number of wound factors that the healthcare professional using them must be aware of. Modern supportive dressings have countless advantages over the classic way of bandaging, and they greatly promote the healing of chronic wounds. A nurse/technician also participates in the care of patients, who greatly contribute to the treatment of chronic wounds. Health care professionals responsible for patients with complex wounds need a special level of expertise and education to ensure optimal wound care, since it is an extremely complex etiology. The education of nurses, who are one of the most important members of the multidisciplinary team that cares for wounds, is extremely important. Education is carried out at the high school, undergraduate, graduate and post-graduate levels of education, and nurses are obliged to continuously improve their skills. Education on care for chronic wounds is conducted at the high school and undergraduate level and is optional. The goal of the research part of the work was to assess the knowledge of nurses/technicians about the application of modern supportive dressings. The research was conducted using an anonymous questionnaire and 196 participants took part in it. The research showed that nurses have knowledge about the characteristics of the wound, but they do not have knowledge about the application of modern support dressings. The conclusion of the research is that nurses and technicians should be further educated on the topic of care for chronic wounds and the use of modern support dressings.
