老年非静脉曲张性上消化道出血患者并发医院感染的危险因素分析

目的探讨老年非静脉曲张性上消化道出血患者并发医院感染发生的危险因素，以利于合理防治。方法回顾性调查老年非静脉曲张性上消化道出血住院患者210例，对69例并发医院感染病例（感染组）与141例未并发医院感染病例（非感染组）进行logistic回归分析。结果210例老年患者中，发生院内感染69例，感染率32．9％。患者营养状况、体力状况、住院时间、侵入性操作与发生医院感染呈显著正相关（P〈0．05），与性别、贫血程度无明显相关性。医院感染部位以下呼吸道和泌尿道、导管相关血源性感染为主，分别占55．1％、40．6％和4．3％。菌群组成以革兰阴性杆菌为主，占64．6％。结论老年上消化道出血患者住院期间易发生医院感染，感染发生与患者营养状况、体力状况、住院时间、侵入性操作有关，应重视危险因素，采取积极应对措施，减少医院感染的发生：

Risk factors of nosocomial infection in elderly patients with nonvariceal upper gastrointestinal bleeding
