Pressure ulcer (lat. decumbere = to lie down) is a localized injury of skin and/or subcutaneous tissue which arises as a result of action of pressure force or the combined action of pressure, shear and sliding (1). Damage is manifested on a thin layer of skin between the protruding bone and the outer surface. As a result, capillary circulation is interrupted, i.e. local tissue ischemia, which causes permanent deterioration of soft tissues. The most common places where pressure ulcer occures are the sacral part of the back (sacrum), petrochanteric regions, heels and ankles. Less common, but also possible places of occurrence of pressure ulcer are the ears, shoulder blades, various parts of the head, etc. According to EPUAP and NPUAP, the classification of pressure ulcer is reflected through four stages and two additional categories. The goal of this research work is to determine the knowledge and attitudes of nurses and technicians about pressure ulcers. The research was conducted among nurses and technicians employed in primary, secondary and tertiary health care, with different education degreeses and different years of service. The data was collected through an anonymous questionnaire created on the Google Forms platform called ''Knowledge and attitudes of nurses and technicians about pressure ulcers''. The survey questionnaire was sent via mobile applications Viber and Whatsapp, and the social network Facebook during March 2023. The survey questionnaire was composed in 3 parts, of which the first part refers to socio-demographic data, the second to questions about knowledge about pressure ulcers and the last to attitudes about pressure ulcers. The questionnaire contains a total of 21 questions. A total of 102 respondents participated in the research, and the results are presented in tables and graphics, and are also described in text. This research has shown that nurses and technicians have a lot of knowledge and positive attitudes about pressure ulcers.
