目的:探讨老年上消化道出血患者医院感染危险因素.方法:对我院2006-2012年收治的282例上消化道出血住院患者病历资料进行回顾性分析,根据患者是否出现医院感染将其分为感染组以及对照组,对两组患者的一般资料等进行分析.结果:单因素分析:性别比、住院时间、抗生素的使用情况、mini评分、合并基础疾病以及年龄等均有相关性(P＜0.05)；多因素分析:mini评分、体力状况评分、侵入性操作以及住院时间、抗生素联合使用情况是导致患者出现医院感染的独立危险因素.结论:mini评分、体力状况评分、侵入性操作以及住院时间、抗生素联合使用情况是导致医院感染的独立影响因素,在治疗中应当对相关因素进行积极处理,以达到预防医院感染的目的.%Objective To investigate the risk factors for nosocomial infection in elderly patients with upper gastrointestinal bleeding. Methods Medical records of 282 elderly inpatients with upper gastrointestinal bleeding from 2006 to 2012 were retrospectively analyzed. All patients were divided into infection group and control group according to the onset of nosocomial infection; the general data of patients in the two groups were analyzed. Results Univariate analysis showed that sex ratio, duration of hospitalization, the use of antibiotics, mini score, combined underlying diseases, and age were the correlated factors for nosocomial infection (P < 0.05). Multivariate analysis showed that mini score, performance status score, invasive operation and hospitalization time, the joint use of antibiotics were independent risk factors for nosocomial infection. Conclusion Mini score, physical status score, invasive procedures and hospitalization time, the joint use of antibiotics were the independent risk factors for nosocomial infection, indicating that active treatments for these relevant factors should be administered to prevent nosocomial infection.
