摘　　要：目的采用Logistic回归模型评价压疮常见危险因素。方法采用病例对照方法,收集我院神经内科近两年住院患者共1973例,用Logistic回归模型对临床常见的压疮危险因素进行分析。结果采用单因素分析,发现卧床时间、意识、活动能力、体位变换能力、皮肤感觉、皮肤状况与压疮的发生明显相关(P<0.01),进一步进行多元逻辑回归分析,发现活动能力和体位变换能力具有较高的相对危险度,其OR值分别为2.87和2.45(P<0.01)。结论采用Logistic回归模型对压疮危险因素进行分析,能够有效甄别出对压疮发生影响较大的高危因素。Objective To evaluate the risk factors of pressure Ulcer based on the logistic regression model. Methods We collected the data of 1,973 hospitalized cases in the Department of Neurology, and analyzed the risk factors of pressure ulcer by logistic regression model in a case control study. Results We found the bed time, consciousness, activity, position change, skin feel and skin condition were related with pressure ulcer significantly based on the univariate analysis （P 〈 0. 01 ）. In addition, the multi- variable logistic regression analysis showed activity（ OR = 2. 87 ） and position change（ OR = 2. 45 ） were the high riskfactors associ- ated with pressure ulcer（ P 〈 0. 01 ）. Conclusion we could screen out the high risk factors of pressure ulcer effectively, based on the analysis of logistic regression model.
