老年慢性心力衰竭患者医院感染相关因素分析

摘要

Objective To explore the related factors of hospital infection in elderly patients with chronic heart failure, and to provide data for infection prevention. Methods The clinical data of elderly patients with chronic heart failure who were treated in our hospital from Apr. 2011 to Jan. 2014 were retrospectively reviewed. The related factors of hospital infection were analyzed. Results Fifty-six cases had hospital infection and the infection rate was 14. 8﹪. Of which 28 patients had respiratory tract infection, 14 urinary system infection, 7 digestive system infection, 5 oral infection and 2 cases with skin ﹠ mucous infection. The hospital infection was correlated with patient's age, disease duration, cardiac functional grading, length of hospital stay, invasive operation, complicated with diabetes mellitus and lung disease ( x2=6. 077, 4. 779, 30. 375, 4. 025, 4. 273, 11. 399 and 7. 005, all P﹤0. 05). Age more than 70 years old, length of hospital stay more than 14 days, invasive operation and complicated with diabetes mellitus were independent risk factors of hospital infection ( OR = 3. 612, 1. 965, 3. 014 and 2. 735, P ﹤ 0. 05 ) . Conclusions Hospital infection rate is high in elderly patients with chronic heart failure, which is associated with multiple factors.%目的：探讨老年慢性心力衰竭患者发生医院感染的相关因素,为临床防治感染提供依据。方法回顾性分析2011年4月至2014年1月我院收治的378例老年慢性心力衰竭患者的临床资料,收集老年慢性心力衰竭患者医院感染的发生情况,并分析其相关因素。结果共56例老年慢性心力衰竭患者发生医院感染,感染率为14.8﹪；其中呼吸道感染28例,泌尿系统感染14例,消化系统感染7例,口腔感染5例,皮肤黏膜感染2例。医院感染与患者的年龄、病程、心功能分级、住院时间、侵入性操作、合并糖尿病和肺部疾病明显相关( x2=6.077、4.779、30.375、4.025、4.273、11.399和7.005,均为P﹤0.05)。年龄＞70岁、住院时间＞14 d、有侵入性操作和合并糖尿病是老年慢性心力衰竭患者发生医院感染的独立危险因素(OR=3.612、1.965、3.014和2.735,均为P﹤0.05)。结论老年慢性心力衰竭患者的医院感染发生率较高,与多个因素相关。临床上应针对医院感染相关危险因素,制定相应的防治措施,减少医院感染发生。
