摘　　要：目的 比较不同临床标本的微生物检验阳性率,为提高微生物检验质量和医院感染管理质量提供可靠依据.方法 研究对象为济南市第二人民医院2016年3月至2018年2月住院患者诊治期间临床采集的细菌培养标本2 028个,采用Micro Scan autoSCAN4全自动细菌鉴定药敏分析仪对其进行检验,严格按照说明书进行规范操作,统计分析各类临床标本的微生物检验阳性率.结果 2 028个临床标本的微生物检验阳性率为 44.33%,其中,痰液标本的微生物检验阳性率最高(58.96%),其次为眼科分泌物标本(40.64%)、眼内容物标本(37.96%)、尿液标本(34.55%)、血液标本(21.11%).结论 不同临床标本的微生物检验阳性率不同,临床上针对不同临床标本的微生物检验情况进行分析,可从侧面了解医院感染的流行病学情况,为临床预防医院感染提供可靠依据,为进一步提高临床微生物检验阳性率,还应针对其影响因素积极实施改进对策.Objective To compare the positive rate of microbiological examination in different clinical specimens,and to provide reliable basis for improving the quality of microbiological examination and management of nosocomial infection.Methods A total of 2 028 bacterial culture specimens were collected from the hospitalized patients in the Second People's Hospital of Jinanfrom March 2016 to February 2018.The samples were examined by Micro Scan autoSCAN4 automatic bacteriological identification analyzer.Strictly according to the specification of the standard operation,the positive rates of microbial testingof all kinds of clinical specimens were statistically analyzed.Results The positive rate of microbiological examination in 2 028 clinical specimens was 44.33%.The positive rate of microbiological examination in sputum was the highest(58.96%),followed by ophthalmic secretion(40.64%),eye contents(37.96%),urine(34.55%),blood(21.11%).Conclusion The positive rate of microbiological examina-tion is different in different clinical specimens.The epidemiological situation of nosocomial infection can be understood by analyzing the microbiological examination of different clinical specimens in clinic.In order to provide a reliable basis for clinical prevention and treatment of nosocomial infection,and to further improve the positive rate of clinical microbiological examination,we should actively carry out improvement countermeasures against its influencing factors.
