背景技术背景：预测压疮风险的Braden量表（Braden量表）已被测试的预测有效性，但黑人的截止分数尚未进行比较，以白色populations. Competitives：这份简短的报告的目的是要确定是否Braden量表预测压疮的风险类似的黑人和白人。在三个城市的疗养院、三级护理和退伍军人管理局医疗中心进行了布雷登量表预测有效性的多点研究（奥马哈，芝加哥，和罗利）选择最大限度地提高种族多样性。共研究了843例受试者，其中666例（79%）为白色，159例（12%）为黑人。两名护士在入院时和出院前每隔一天使用Braden量表或皮肤评估工具对每个随机选择的受试者进行独立评估。白人的压疮发生率（15%）高于黑人（5%），但两组间平均Braden量表评分无统计学显著差异（19.4，2.8，白色对比19.8，2.75，黑色）。18分最能预测两组的风险（敏感性70%，特异性77%，白人预测正确率为75%，黑人预测正确率为76%，敏感性75%，特异性76%）。受试者-操作者特征（ROC）曲线下面积无差异（0.75，0.03，白色和0.82，0.07，黑人受试者，= 0.005）。结论：得分18可用于识别黑人和白色个体的压疮风险。
BACKGROUND: The Braden Scale for Predicting Pressure Sore Risk (Braden Scale) has been tested for predictive validity, but the cut-off scores for Blacks has not been compared to White populations.OBJECTIVES: The purpose of this brief report is to determine if the Braden Scale predicts pressure ulcer risk similarly for Blacks and Whites.METHOD: A multisite study of the predictive validity of the Braden Scale was conducted in nursing homes, tertiary care, and Veteran's Administration Medical Centers in three cities (Omaha, Chicago, and Raleigh) selected to maximize ethnic diversity. A total of 843 subjects, 666 (79%) White, 159 (12%) Black were studied. Two nurses independently rated each randomly selected subject on admission and every other day until discharge, using the Braden Scale or the Skin Assessment Tool.RESULTS: Whites had a higher incidence of pressure ulcers (15%) than did Blacks (5%), but there was no statistically significant difference in the mean Braden Scale score between groups ( 19.4, 2.8, White versus 19.8, 2.75, Black). A score of 18 best predicts risk for both groups (sensitivity 70%, specificity 77%, with 75% correct predictions for Whites and sensitivity 75%, specificity 76%, with percent correct 76% for Blacks). There was no difference in the area under the receiver-operator characteristic (ROC) curves (0.75, 0.03, White and 0.82, 0.07, Black subjects, =.005).CONCLUSIONS: A score of 18 can be used for identifying Black and White individuals at risk for pressure ulcers.
