改进痰培养标本采集方法对细菌学检验质量的影响

Effect of Improved Sputum Culture Collection Method on Bacteriology Inspection Quality

探析改进痰培养标本采集方法对细菌学检验质量的影响。选取120例做痰培养的患者为研究对象,采用抽签法将其平均分为常规组和实验组。常规组患者采用自然咳痰法采集痰液,实验组患者采用改进痰培养标本采集方法进行采集。比较两组患者痰培养标本的采集时间、痰培养标本的合格率和实验室痰培养阳性检出情况。结果表明:实验组患者的痰培养采集时间及检验时间均显著短于常规组(P<0.05),差异有统计学意义;实验组患者的痰培养标本合格率显著高于常规组(P<0.05),差异有统计学意义。实验组患者的痰培养标本阳性检出率显著高于常规组(P<0.05),差异有统计学意义。改进痰培养标本采集方法能够显著缩短痰液收集时间,减轻痰液标本被污染的几率,提高细菌学检验质量。

The research explores the effect of improved sputum culture collection method on bacteriology inspection quality.120 patients who receive sputum culture are selected as the research objects,and they are equally divided into routine group and experimental group with lottery method.Patients in routine group adopt expectoration method to collect sputum,and patients in experimental group adopt improved sputum culture collection method.Collection time,percent of pass of sputum culture samples and the positive detection rate of laboratory sputum culture of two groups are compared.The results show that collection time and inspection time of experimental group are shorter than routine group,with statistically significant difference(P<0.05).Percent of pass of sputum culture samples of experimental group is significantly higher than control group,with statistically significant difference(P<0.05).Positive detection rate of laboratory sputum culture of experimental group is significantly higher than routine group,with statistically significant difference(P<0.05).With improved sputum culture collection method,we can significantly shorten sputum collection time,reduce the possibility of the contamination of sputum samples,and improve bacteriology inspection quality.
