重症监护室的患者比其他患者发生压疮的风险更高。为了防止重症监护患者发生压疮，必须准确评估压疮发生的风险。通过使用来自电子健康记录的4年数据，评价Braden量表评估重症监护患者发生压疮风险的预测有效性。从2007年1月1日至2010年12月31日期间入住重症监护室的患者的电子健康记录中提取的数据来自学术医疗中心的数据仓库。预测有效性通过敏感性、特异性、阳性预测值和阴性预测值来衡量。生成受试者工作特征曲线，并报告曲线下面积。共有7790名重症监护患者纳入分析。Braden量表的临界值为16分，敏感性为0.954，特异性为0.207，阳性预测值为0.114，阴性预测值为0.977。曲线下面积为0.672（95% CI，0.663-0.683）。根据受试者工作特征曲线确定的重症监护患者的最佳截止值为13。Braden量表在鉴别有压疮发生风险的重症监护患者方面显示出不足的预测有效性和较差的准确性。Braden量表可能无法充分反映重症监护患者的特征。需要进一步的研究来确定哪些可能的预测因素是特定于重症监护病房，以增加布雷登量表预测重症监护患者压疮的有用性。
Patients in intensive care units are at higher risk for development of pressure ulcers than other patients. In order to prevent pressure ulcers from developing in intensive care patients, risk for development of pressure ulcers must be assessed accurately. To evaluate the predictive validity of the Braden scale for assessing risk for development of pressure ulcers in intensive care patients by using 4 years of data from electronic health records. Data from the electronic health records of patients admitted to intensive care units between January 1, 2007, and December 31, 2010, were extracted from the data warehouse of an academic medical center. Predictive validity was measured by using sensitivity, specificity, positive predictive value, and negative predictive value. The receiver operating characteristic curve was generated, and the area under the curve was reported. A total of 7790 intensive care patients were included in the analysis. A cutoff score of 16 on the Braden scale had a sensitivity of 0.954, specificity of 0.207, positive predictive value of 0.114, and negative predictive value of 0.977. The area under the curve was 0.672 (95% CI, 0.663–0.683). The optimal cutoff for intensive care patients, determined from the receiver operating characteristic curve, was 13. The Braden scale shows insufficient predictive validity and poor accuracy in discriminating intensive care patients at risk of pressure ulcers developing. The Braden scale may not sufficiently reflect characteristics of intensive care patients. Further research is needed to determine which possibly predictive factors are specific to intensive care units in order to increase the usefulness of the Braden scale for predicting pressure ulcers in intensive care patients.
