摘要
目的探讨高龄老年患者发生医院内感染情况。方法回顾性分析2006年12月至2016年12月1 552例住院高龄患者发生院内感染的临床资料,探究发生感染的常见部位、危险因素以及院内感染的常见致病菌,从而掌握高龄患者院内感染的特点,以采取相应措施减少院内感染及合理选择用药。结果老年患者发生院内感染部位最常见部位为下呼吸道,其次为泌尿道。年龄、基础疾病、住院时间、侵入性治疗、长期使用抗生素等均为发生院内感染的危险因素。院内感染的致病菌中,革兰氏阴性菌中多见的有铜绿假单胞菌、肺炎克雷白杆菌、鲍曼不动杆菌及大肠埃希氏菌,革兰氏阳性球菌多见的为肠球菌、金葡菌。结论院内感染影响因素较多,以感染耐药菌多见,高龄老年患者发生院内感染主要发生于呼吸系统和泌尿系统。临床医师应掌握耐药特点合理用药,进行针对性地预防及治疗。
Objective To investigate the nosocomial infection in hospitalized elderly patients. Methods A retrospective study was performed on 1 552 cases of hospitalized elderly patients with nosocomial infection from December 2006 to December 2016. To investigate the common site of infection,risk factors and common pathogenic bacteria of nosocomial infection,to master the characteristics of elderly patients with nosocomial infection,to take corresponding measures to reduce hospital infection and rational selection of drug use. Results The nosocomial infection site was at lower respiratory tract,followed by urinary infection. Age,basic diseases,hospitalization time,aggressive treatment,long-term use of antibiotics were the related risk factors of nosocomial infection. Gram negative bacteria was in the most common drug-resistant bacterias of nosocomial infection,such as Pseudomonas aeruginosa,Klebsiella pneumoniae,Bauman Acinetobacter and Escherichia coli,Gram positive cocci were Enterococcus and Staphylococcus aureus. Conclusion There are many risk factors of nosocomial infection,especially the drug-resistant bacterias are the most common. Nosocomial infection is more common in the lower respiratory system and urinary system of hospitalized elderly patients. Clinical medical workers should grasp the clinical characteristics of nosocomial infection in hospitalized patients and adopt corresponding prevention and treatment.
