某三甲医院耐甲氧西林金黄色葡萄球菌流行分布及医院感染特征分析

The Prevalence Characteristics of Mehticillin-resisitan Staphylococcus aureus(MRSA)in a Tertiary Hospital from 2018 to 2020

目的 研究2018—2020年某三甲医院耐甲氧西林金黄色葡萄球菌流行分布及医院感染特征,为精准化防控提供更多依据。方法 医院感染管理科专职人员,按照统一的调查内容与调查表、统一诊断标准,对耐甲氧西林金黄色葡萄球菌(MRSA)的住院患者资料进行回顾性调查及数据分析。结果 MRSA检出率逐年升高;呼吸科、ICU的MRSA检出率、MRSA多重耐药菌感染发现率、MRSA感染千日发生率等均高于其他科室,P值有统计学意义;MRSA检出阳性病例中社区感染42.5%;定植状态占28.75%;医院感染占28.75%。医院感染病例中,以呼吸系统感染为主占62.35%;男女比例3.26:1;年龄分布以70~90岁为主,占64.5%。结论 MRSA检出率逐年升高要引起重视,尤其是呼吸科、ICU等MRSA检出率、MRSA多重耐药菌感染发现率、MRSA感染千日发生率均高于其他科室的部门,要加强防控措施的规范落实。对MRSA检出阳性病例要及时判断医院感染、定植、社区感染等状态,利于诊治措施的分类实施;对于医院感染病例,要根据其感染部位及年龄特征落实诊治及防控措施。

Objective Study the prevalence characteristics of Mehticillin-resisitan Staphylococcus aureus(MRSA)in atertiary hospital from 2018 to 2020,to provide more precise basis for prevention and controlling MRSA.Methods The staff of the hospital infection management department judged the MRSA was hospital infection,implantation or the community infection according to the unified method with the same diagnostic standard.The inpatients of MRSA infected were conducted a retrospective investigation.Results The detection rate of methicillin resistant Staphylococcus aureus (MRSA) was increased year by year.The detection rate,infection rate of multiple resistant bacteria in respiratory and ICU department were higher than other departments.The community infection and implantation status of MRSA positive cases accounted for 71.25%.The hospital infection accounted for 28.75%.Among hospital infections,respiratory infections accounted for 62.35%.The rate of male and female was 3.26:1,and age mainly distribution were 70~90 years,accounted for 64.5%.Conclusions Comprehensive measures should be taken to reduce the detection of MRSA.For positive cases,hospital infection,implantation status and community infection should be timely analyzed,and targeted prevention and control measures should be taken.
