某综合医院血培养标本送检状况调查

目的 调查某综合医院2011年第1季度血培养标本的送检状况,为规范化措施的制定提供依据.方法 记录1 879份血培养标本的采集时间、上机时间、送检瓶数、采血量以及培养结果等信息进行分析.结果 延迟2 h以上送检的有1 063份血培养标本,延迟送检率高达56.6%.抽查579份血培养标本中,采血量不足的占47.5%.整个病程单瓶送检率高达76.6%,血培养阳性率低,仅为6.7%,占第1位的分离菌是凝固酶阴性葡萄球菌.结论 血培养标本的采集和送检过程极不规范,需对血培养实验前的质量控制进行干预.

Investigation of blood culture specimen inspection situation in a general hospital

Objective To investigate the blood culture specimen inspection situation in a general hospital in the first season of 2011,so as to provide a scientific basis for standardizing regulation.Methods 1 879 blood culture specimens were recorded about the collection time,the time entry into the blood culture system,the number of consecutive cultures,the volume of blood,and the pathogenic bacteria detected.Results 1 063 blood culture specimens(1 063/1 879,56.6%) were delayed to laboratory more than 2 hours.The volume of blood in 275 bottles(275/579,47.5%) was inadequate.1 439 blood culture specimens(1 439/1 879,76.6%) were single bottle inspection throughout the course of disease.126 strains(6.7%) were isolated from 1 879 specimens.Coagulase-negative Staphylococcus(43 strains) was the predominant.Conclusion Blood culture specimens sampling and inspection are not standard.It is necessary to intervene in the quality control before experiment.
