The predictive validity of the Braden Scale and the timing of assessment for optimal prediction of pressure sore development (PS) were studied in a nursing home population. Subjects (N = 102) over age 19, free of PS and admitted within the previous 72 hr, were randomly selected from consecutive admissions to a skilled nursing facility. Subjects were assessed for risk and skin condition every 48 to 72 hr for 4 weeks. Twenty-eight subjects (27.5%) developed a PS. A cut score of 18 used at the observation prior to the first recorded PS maximized prediction, producing a sensitivity of 79%, a specificity of 74%, a 54% predictive value of a positive test, 90% predictive value of a negative test, and 75% correct classification rate.
在养老院人群中研究了Braden量表的预测效度以及为最佳预测压疮发生（PS）而进行评估的时机。从一家专业护理机构的连续入院患者中随机选取了19岁以上、无压疮且在过去72小时内入院的102名受试者。在4周内，每48至72小时对受试者进行一次风险和皮肤状况评估。28名受试者（27.5%）发生了压疮。在首次记录压疮之前的观察中使用的18分的临界值可使预测最大化，其敏感性为79%，特异性为74%，阳性试验预测值为54%，阴性试验预测值为90%，正确分类率为75%。
