SUMMARY
Objective: To identify risk factors for the formation of UP and analyze the main characteristics of patients suffering from such injuries Internal Medicine (CM) and Intensive Care Unit (ICU). Method: The sample consisted of patients older than 18 years admitted to the CM and the ICU of a hospital Pernambuco interior. They were evaluated by EB patients without PU; in patients with UP installed was applied semi-structured questionnaire containing questions about the risk factors and complications related to UP; The records were analyzed to complement the information. Results: We submitted to EB 573 patients, most presented low risk (51.5%). Among patients at high risk, most belonged to the older age than 60 years (44.0%), which are also prevalent among patients with UP already installed (63.3%). The ICU patients had a higher risk compared to the CM. Of the 30 patients with PU installed, UP 7% acquired in extra-hospital and 93% in-hospital, among the underlying diseases of the vascular origin had a higher incidence. The sacral region was the most affected (53%). Of the 46 injuries installed 36% were stage II. Descriptors: Pressure Úlcers. Risk Factors. Health of the Elderly.
