临床标本微生物检验结果阳性率情况分析

periods and different types of clinical specimens

目的探讨不同时段且不同类型的临床标本微生物检验结果阳性率分布情况。方法收集东丽医院用药前临床标本1000例,设置为对照组,并收集用药后的临床标本1000例,设置为观察组。对两个时段的临床标本微生物检验阳性率进行比较,分析不同时段不同类型的临床标本微生物检验结果阳性率分布情况。结果对照组呼吸道标本微生物、非呼吸道标本微生物、血培养标本微生物检验阳性率明显高于观察组,差异均有统计学意义(P<0.05)。但两组标本在粪便标本的微生物检验阳性率上差异无统计学意义(P>0.05)。结论临床用药前采集的呼吸道标本、非呼吸道标本以及血液标本的微生物检验阳性率会升高,但粪便标本微生物检验差异不明显。通过这种手段能够提升疾病诊断的准确性,值得临床推广应用。

Objective To investigate the positive rate distribution of microbial test results in different periods and different types of clinical specimens. Methods 1 000 clinical specimens were collected before treatment and set as control group. Another 1 000 clinical specimens after the treatment were collected and set as observation group. The positive rates of microbiological examination of clinical specimens in two periods were compared,and the positive rate distribution of different periods and different types of clinical specimens were analyzed. Results In the control group,the positive rate of respiratory specimen microbe,non respiratory specimen microbe and blood culture specimen microbe were higher than those in the observation group,the differences above were statistically significant（P〈0.05）. However,there was no significant difference between the two groups in the positive rate of stool specimens（P〉0.05）. Conclusion The positive rate of microbial examination of respiratory specimens microbe,non respiratory specimen microbe and blood culture specimen microbe will increase collected before clinical medication,but there was no significant difference in the detection of fecal samples. This method can improve the accuracy of disease diagnosis,and is worthy of popularization and application.
