老年医学科医院感染现状及抗菌药物使用分析

Analysis on the status of healthcare-associated infection and the use of antibiotics in the Department of Geriatrics

目的分析本院老年住院患者医院感染的特点及抗菌药物使用情况。方法对本院老年医学科住院患者医院感染的部位、年龄、致病菌、抗菌药物等进行回顾性分析。结果 3 008例老年住院患者病例资料,699例次(506人次)符合医院感染诊断标准,发生率为23.3%;80岁以上的高龄老人更容易合并感染(占90.9%),肺部感染居首位(占46.5%),其感染的病原微生物以革兰阴性杆菌为主(占55.0%),β内酰胺类抗菌药物应用最为广泛(占70.5%)。结论老年患者医院感染发病率高,通过对感染易发部位,常见病原微生物及敏感抗菌药物等的分析,可早期预防及针对性的治疗。

Objective The characteristics of healthcare-associated infection(HAI)and the use of antibiotics in the elderly hospitalized patients in our hospital were analyzed.Methods The location,age,pathogenic bacteria and antimicrobial agents of HAI in the Department of geriatrics of our hospital were analyzed retrospectively.Results 3 008 cases of elderly hospitalized cases,699 cases(506 times)were in line with the diagnostic standard of HAI,the incidence rate was 23.3%.Over the age of 80,the oldest old is more likely to infection(90.9%).Lung infection is the leading cause(46.5%).The most common pathogenic bacteria are gram negative bacilli(55.0%),and beta lactam antibiotics are the most widely used(70.5%).Conclusion The incidence of HAI in elderly patients is high.Early prevention and targeted treatment can be achieved through analyzing the vulnerable sites,common pathogenic microorganisms and sensitive antibiotics.
