目的分析并探讨不同临床标本微生物检验的阳性率流行病学特点。方法选取2010年11月~2014年11月在本院检测的不同临床标本。其中2010年11月~2012年11月为一组,2012年11月~2014年11月为一组。采用全自动细菌鉴定药敏分析仪,根据操作规则检测结果 ,并进行总结分析。结果 2010年11月~2012年11月临床标本检验阳性率为28.18%(1105/3921),其中,呼吸道标本检验阳性率为35.55%(758/2132),血培养标本检验阳性率为7.67%(53/691),大便标本检验阳性率为0.97%(2/206),其他非呼吸道标本检验阳性率为32.74%(292/892)。2012年11月~2014年11月临床标本检验阳性率为24.70%(1310/5304),其中,呼吸道标本检验阳性率为31.04%(825/2658),血培养标本检验阳性率为9.77%(104/1065),大便标本检验阳性率为1.09%(3/274),其他非呼吸道标本检验阳性率为28.92%(378/1307)。2010年11月~2012年11月临床标本阳性率以及呼吸道标本阳性率明显高于2012年11月~2014年11月(P<0.05)。结论分析并探讨不同临床标本微生物检验的阳性率流行病学特点,对于临床检验和诊断有重要意义。
Objective To analyze and discuss the epidemiological characteristics of positive rate of microbiological tests in different clinical specimens. Methods Selected from November 2010 to November 2014 in our hospital for the detection of different clinical specimens. One November 2010 ~ November 2012 for a group, November 2012 ~ November 2014 as a group. The use of automatic bacterial identification susceptibility analyzer, according to the rules of operation test results and analysis. Results The positive rate of clinical specimens from November 2010 to November 2012 was 28.18% (1105/3921). The positive rate of respiratory specimens was 35.55% (758/2132) and the positive rate of blood culture specimens was 7.67% ( 53/691). The stool specimen positive rate was 0.97% (2/206). The positive rates of other non-respiratory specimens were 32.74% (292/892). The positive rate of clinical specimens was 24.70% (1310/5304) between November 2012 and November 2014, of which the positive rate of respiratory specimens was 31.04% (825/2658), and the positive rate of blood culture specimens was 9.77% (104 / 1065). The stool specimen positive rate was 1.09% (3/274). The positive rate of other non-respiratory specimens was 28.92% (378/1307). The positive rate of clinical specimens and the positive rate of respiratory specimens from November 2010 to November 2012 were significantly higher than that from November 2012 to November 2014 (P <0.05). Conclusion It is important to analyze and discuss the epidemiological characteristics of the positive rate of microbiological tests of different clinical specimens for clinical examination and diagnosis.
