摘要
目的分析不同临床标本微生物检验的阳性率与流行病学分布。方法标本检验时间介于2018年5月—2020年6月间,共计临床标本900份,粪便标本计入155份,呼吸道标本计入348份,血液标本计入271份,尿液标本计入126份。病房分布为:呼吸病房377份,心内病房160份,普外病房108份,消化病房255份。对比不同标本与病房的微生物阳性率,并记录病原菌分布情况。结果粪便标本的阳性率为7.10%,呼吸道标本的阳性率为34.20%,血液标本的阳性率为9.96%,尿液标本的阳性率为38.10%,尿液标本与血液、粪便标本对比,差异有统计学意义(χ^(2)=44.424、40.261,P<0.001)。呼吸道标本与粪便、血液标本对比,差异有统计学意义(χ^(2)=41.089、49.638,P<0.001)。呼吸病房的阳性率为33.95%,心内病房为12.50%,普外病房为6.48%,消化病房为12.16%,呼吸病房与心内、普外、消化病房对比,差异有统计学意义(χ^(2)=25.892、31.539、38.377,P<0.001)。结论尿液标本的阳性率最高,且流行病学显示微生物阳性多分布在呼吸病房,需要明确分析阳性率高的原因,并进行质控管理,进而科学指导临床诊治工作。
Objective To analyze the positive rate and epidemiological distribution of microbiological tests of different clinical specimens.Methods Specimen inspection time was between May 2018 and June 2020.A total of 900 clinical specimens were included,stool specimens are counted as 155,respiratory tract specimens were counted as 348,blood specimens were counted as 271,and urine specimens were counted 126 copies.The wards were distributed as follows:377 respiratory wards,160 intracardiac wards,108 general surgery wards,and 255 digestive wards.Compared the positive rates of microorganisms in different specimens and wards,and record the distribution of pathogens.Results The positive rate of stool specimens was 7.10%,the positive rate of respiratory tract specimens was 34.20%,the positive rate of blood specimens was 9.96%,and the positive rate of urine specimens was 38.10%.Comparing urine specimens with blood and stool specimens,the difference was statistically significant(χ^(2)=44.424,40.261,P<0.001).The respiratory specimens were compared with the feces,blood specimens,and the difference was statistically significant(χ^(2)=41.089,49.638,P<0.001).The positive rate of the respiratory ward was 33.95%,the cardiac ward was 12.50%,the general surgery ward was 6.48%,and the digestive ward was 12.16%.The difference was statistically significant between respiratory ward and cardiac ward,general ward and digestive ward(χ^(2)=25.892,31.539,38.377,P<0.001).Conclusion The positive rate of urine specimens is the highest,and epidemiology shows that microbe positives are mostly distributed in the respiratory ward.It is necessary to analyze the reasons for the high positive rate and carry out quality control management to scientifically guide clinical diagnosis and treatment.
