Purpose : Currently the Braden Scale is very popular for use in predicting pressure ulcer development.However, when we used this scale in clinical studies in hospitals in Japan, the specificity was below 70%. The braden Scale's constant use of the same subcategorize during patient treatment does not consider other factors which change over time.The purpose of this study is to establish a new scale for pressure ulcer prediction and evaluate the predictive validity.Method1. We performed inductive analysis in the changes of factors affecting pressure ulcer development2. We established a conceptual framework using above factors, and a conductive new scale3. We compared the predictive validity using the sensitivity and specificity between the new scale (K-scale) and Braden Scale.Results1. Risk FactorsThere were three categories affecting pressure ulcer development over the course of time : (1) the predisposing factors, (2) nursing intervention, (3) the trigger factors. The subcategories in … More the predisposing factor consisted of incapability of position change, degree of bony prominence, malmutrition and head elevation of the bed. Those in nursing intervention consisted of selecting appropriate support surfaces and availability of a caretaker. Those in he trigger fators consisted of skin irritation, respiratory and circulatory insufficiency, and degree of inappropriate position change.2. Conceptual Framework and New Predictive Pressure Ulcer Scale (K-scale)The conceptual framework for pressure ulcer development which we established using the risk factors above investigated the content validity. (by the researchers and unrses who were familiar with pressure ulcers.) We established a new scale involving the quantitative categories by selecting the key factors from the conceptual framework. The new scale divided two parts. One was the predisposing categories, the other was the trigger categories.3. Evaluate the Predictive Validity of New ScaleWe calculated the sensitivity and specificity of the new scale versus the Braden scale on 107 hospitalized elderly patients. The both of sensitivity and specificity of the new scale was higher than that of the Braden Scale.ConclusionWe believe that the new scale which we developed is more predictive than the Braden Scale.

目的：目前Braden量表在预测压疮发展方面非常流行。然而，当我们在日本医院使用该量表进行临床研究时，特异性低于70%。 Braden量表在患者治疗过程中不断使用相同的子类别，没有考虑随时间变化的其他因素。本研究的目的是建立一个新的压疮预测量表并评估其预测有效性。方法1．我们对影响压疮发生的因素的变化进行了归纳分析2。我们利用上述因素建立了一个概念框架，以及一个传导性的新尺度3。我们使用新量表（K 量表）和 Braden 量表之间的敏感性和特异性比较了预测有效性。结果1。危险因素随着时间的推移，影响压疮发展的因素有三类：(1)诱发因素，(2)护理干预，(3)触发因素。诱发因素的子类别包括无法改变体位、骨突出程度、营养不良和床头抬高。护理干预包括选择适当的支撑表面和看护人员的可用性。诱发因素有皮肤刺激、呼吸循环功能不全、体位改变程度不适当等。 2．概念框架和新预测压疮量表（K量表）我们利用上述风险因素建立的压疮发展概念框架调查了内容有效性。 （由熟悉压疮的研究人员和非护士组成。）我们通过从概念框架中选择关键因素，建立了一个涉及定量类别的新量表。新的量表分为两部分。一是诱发类别，二是触发类别。3．评估新量表的预测有效性我们对 107 名住院老年患者计算了新量表与 Braden 量表的敏感性和特异性。新量表的敏感性和特异度均高于Braden量表。结论我们认为我们开发的新量表比Braden量表更具预测性。较少的
