失禁患者发生失禁相关性皮炎危险因素的Logistic回归分析

Logistic Regression Analysis of Risk Factors of Incontinence-Associated Dermatitis among Patients with Incontinence

目的探讨失禁患者发生失禁相关性皮炎(incontinence-associated dermatitis,IAD)的危险因素。方法选取一段时间内某院普通病区和监护病区的失禁患者121例,记录性别、年龄、是否存在慢性病、失禁类型、失禁次数、有无进行机械通气、营养支持方式、白蛋白水平、抗生素种数、供氧方式、是否使用镇静剂、Braden评分、体温等13个指标,对可能影响失禁相关性皮炎发生的因素作单因素分析与Logistic多元回归分析。结果单因素分析共筛选出白蛋白水平、供氧方式、有无进行机械通气、是否使用镇静剂、体温、失禁次数、是否存在慢性病、抗菌药物种数、Braden评分9方面因素有统计学意义(均P<0.05);以有失禁相关性皮炎发生为应变量,其他因素为自变量赋值后进行非条件多因素回归分析,最终显示抗菌药物种数和Braden评分2方面因素是失禁患者发生失禁相关性皮炎的危险因素。结论合理使用抗菌药物,科学地使用Braden量表,能有效预防失禁相关性皮炎的发生。

Objective To explore risk factors of incontinence-associated dermatitis （IAD） in patients with incontinence. Methods Totally 121 patients with incontinence in general wards and care units were included in this study and 13 parameters including gender, age, with chronic disease or not, types of incontinence, frequency of incontinence, with mechanical ventilation or not, modes of nutrition support, albumin, species of antibiotics, methods of oxygen supplying, with sedative or not, Braden scores, body temperature were recorded respectively. The potential influencing factors were analyzed by single factor analysis and logistic regression analysis. Results Single factor analysis revealed that incontinence-associated dermatitis was related with nine factors （P〈 0.05）, which involved albumin, methods of oxygen supplying, with mechanical ventilation or not, with sedative or not, body temperature, frequency of incontinence, with chronic disease or not, species of antibiotics and Braden scores. Logistic regression indicated that risk factors included species of antibiotics and Braden scores. Conclusion Reasonable application of antibiotics and Braden scale are beneficial to effective prevention of IAD.
