RESUMO:

The objective of this study was to validate the nursing diagnosis “Pressure ulcer risk” in patients admitted to the intensive care unit. Faced with the severity, complexity and degree of dependence of the critical patients, nursing needs to assess the presence of this diagnosis to act in the prevention of risk factors and maintenance of quality in the services offered. This was a methodological study, conducted in three steps: concept analysis, content analysis by experts and clinical validation. The first step was based on the model of Walker and Avant and performed through literature review, which occurred in the months of February and March 2015. We used the databases: Scopus, Latin American and Caribbean Health Sciences Literature, Cumulative Index to Nursing and Allied Health Literature, National Library of Medicine and National Institutes of Health, and Web of Science, and the descriptors: pressure ulcer, risk factors and intensive care units, and their respective synonyms in the English language. We obtained a sample of 22 papers. After completing the concept analysis, we identified 42 backgrounds and the following essential attributes: Pressure; Pressure combined with shearing; and Tissue ischemia. In the second step, we asked the experts to give opinions about the concept analysis, by means of a focus group, composed of seven nurses, in four meetings, which were held from May to July 2015. After finishing the discussion in the focus group, we had a total of 29 backgrounds, besides the following conceptual definition for the diagnosis under study: Vulnerability of rupture of the skin integrity as a result of the tissue ischemia provoked by pressure or pressure combined with shearing. In the third step, we conducted a case-control study with the aim of assessing, in clinical practice, the accuracy of the risk factors of the nursing diagnosis identified and validated in the preceding steps. This step took place in the intensive care unit of the Onofre Lopes University Hospital, through a form. The sample was composed of 180 participants, with 90 in the case group and 90 in the control group. The research project was submitted and approved by the Research Ethics Committee of the aforementioned hospital, under Protocol number 848.997 and Presentation Certificate for Ethics Assessment number 36883714.5.0000.5292. The results show that, through the application of the hierarchical logistic regression model, a set of five risk factors and one clinical aspect must be regarded as a strong indicator of the increased risk for pressure ulcer. The risk factors were: History of pressure ulcer; Extended period of stay in the ICU; Friction, Dehydration and High Temperature. As for the clinical aspect, it was: Treatment of comorbidities. We conclude that there is a set of variables that increase the chance of occurrence of the nursing diagnosis “Pressure ulcer risk” in patients admitted to the intensive care unit. Accordingly, we believe that this study has contributed to the improvement of the diagnostic parlance, with regard to adopting preventive measures, applying more effective interventions, achieving positive results and improving the quality of the health care provided by the nursing professional.
