Development of new predictive pressure ulcer scale involving quantitative categories.

目的：目前，Braden量表在预测压疮发展方面非常流行，但是，当我们在日本医院的临床研究中使用该量表时，特异性低于70%。Braden量表在患者治疗过程中经常使用相同的子分类，没有考虑其他随时间变化的因素。本研究的目的是建立一个新的压疮预测量表，并评价其预测效度。对影响压疮发生的因素变化进行归纳分析。我们建立了一个概念框架，使用上述因素，和一个新的导电规模3。比较新量表（K-scale）与Braden量表的敏感性和特异性。影响压疮发生的危险因素有三种：（1）诱发因素，（2）护理干预，（3）触发因素。中的子类别 ...更多信息 易患因素包括不能改变体位、骨性突出程度、畸形、床头抬高等。护理干预包括选择适当的支持表面和护理人员的可用性。诱发因素包括皮肤刺激、呼吸循环功能不全、体位改变不适当程度.概念框架和新的压疮预测量表（K量表）我们使用上述危险因素建立的压疮发展的概念框架调查了内容效度。(by熟悉压疮的研究人员和UNRSE。）我们建立了一个新的规模涉及的数量类别选择的关键因素的概念框架。新的比额表分为两部分。一个是诱发类别，另一个是触发类别。对107例住院老年患者进行新量表与Braden量表的敏感度和特异度比较。新量表的敏感性和特异性均高于Braden量表。结论我们认为新量表比Braden量表具有更好的预测性。少

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.
