Abstract
Objective To investigate the sensitivity, specificity and Cut-off value of the Braden scale for predicting pressure sore risk in critical care patients. Method This study was a cross-sectional descriptive study. The Brandon scale was used to assess the risk of pressure sore in 1547 ICU patients who were purposely sampled within 24 hours of admission. Data on 1075 patients who did not have pressure ulcers at the time of admission to the ICU were included in the analysis. Results The score of Braden scale was 6 to 18 points with an average of 12.30±1.44 points. The incidence of pressure sores during ICU admission was 12.1%. Age, length of hospital stay, disease severity and the score of Braden scale were considered for predicting pressure ulcers. When the cut-off value of pressure sores was 11 or 12 points, the sensitivity was 34.6% or 66.9%, and the specificity was 75.9% or 43.4%, respectively. The cut-off values of disease severity were not less than 19.5 or 20.5 point with the sensitivity of 62.3% or 56.2% and the specificity of 49.9% or 56.8%. Conclusions The Braden Scale can be used to predict the risk of pressure ulcers in critical care patients, but cut-off values need to be explored in evidence-based practice. The assessment indicators and criteria need to be further supplemented and quantified. The disease severity can predict the risk of pressure sores. The age of the patient and length of hospital stay should be considered as risk factors for pressure ulcers.
