[摘要] 目的 了解和分析本院不同临床标本微生物检验的阳性率,为临床各科室提供有价值的流行病学参考。方法 选取2013年2~6月临床标本1876份,2013年7~11月临床标本1870份。检测细菌阳性率。 结果 2013年2~6月间,我院血液、尿液以及呼吸道标本的阳性率分别为13.82%、39.18%、48.98%,均高于2013年7~11月间相同标本阳性率(9.59%、32.65%、41.31%),差异有统计学意义(χ2=3.8479,P=0.0498;χ2=4.1968,P=0.0405;χ2=6.0739,P=0.0137)。两个时间段内痰液标本阳性率比较(20.54% vs 19.62%),差异无统计学意义(χ2=0.0236,P=0.8778)。结论 分析不同时间段医院临床标本微生物检测的阳性率情况可为临床各科室提供有意义的流行病学参考信息,同时可提高临床诊断水平,指导临床疗效观察及预后判断。

[Abstract] Objective To understand and analyze the positive rate of the different clinical specimens of microbiological examination, provide epidemiology reference value for clinical departments. Methods A total of 1876 clinical specimens from February to June 2013 and 1870 clinical specimens from July to November 2013 were respectively selected, to exam the positive rate of bacteria. Results From February to June 2013, the positive rate of blood, urine and respiratory specimens in our hospital were respectively 13.82%, 39.18% and 48.98%, were higher than that in July to November 2013 (9.59%, 32.65%, 41.31%),was statistical significance (χ2=3.8479,P=0.0498;χ2=4.1968,P=0.0405;χ2=6.0739,P=0.0137),the comparative difference of the positive rates of sputum specimens in two periods (20.54% vs 19.62%), had no statistical significance (χ2=0.0236,P=0.8778). Conclusion The analysis of the positive rates of clinical microbiological specimens examination in the hospital in different periods can provide meaningful clinical epidemiological reference information for variously clinical departments, at the same time, it also can improve clinical diagnosis level and guide the observation of clinical curative effect and prognosis judgement.

临床标本微生物的检验可为临床感染类疾病的预防、诊治、预后提供科学依据和参考,对提高临床标本阳性检出率具有重要意义[1]。随着现代科技水平的进步和发展,临床标本微生物检测技术已向自动化、微量化方向发展。相关报道显示[2],标本微生物检测结果并未达到人们满意的结果,存在较多问题,其中标本阳性率较低是主要缺点之一,影响感染性疾病的治疗。本文将我院2013年2~6月与2013年7~11月不同临床标本微生物阳性率作对比分析,现将结果报道如下。
