Abstract

This methodological study aimed to evaluate the predictive validity of the Braden scale in critical care patients. The study was conducted in four intensive care units of a general private hospital. After approval of the project by the Hospital Ethics Committee, during six months, adult patients admitted to ICUs with a Braden score <18 and without PU were assessed upon admission and at 48-hours intervals as long as the patient remained at risk or until the development of PU, patients' discharge, death or transfer from the ICU. The cut-off scores of the Braden scale in the first, second and third assessments were 12, 13 and 13, respectively. Sensitivity was 85.7%, 71.4% and 71.4% and specificity was 64.6%, 81.5% and 83.1%, respectively. Areas under the ROC curves revealed very good accuracy for the cut-off scores. The Braden cut-off score 13 in the third assessment showed the best predictive performance in critical care patients.
