新生儿血培养阳性标本的目标性监测和假阳性控制研究

摘要

Objective To explore the causes of false positive in neonatal blood culture and its countermeasures and application value.Methods The positive cases of neonatal blood culture from January 2013 to December 2015 were retrospectively studied, to analyze the main causes of false positives and to timely apply the corresponding measures.Results Conditional pathogenic bacteria belongs to main false positive cases; the false positive rate before intervention is 24.6%, the false positive rate is 6.5% after intervention. The difference has statistical signiifcance (P<0.05). Conclusion In neonatal blood culture positive specimens, the false positive cases is more, which need to strengthen the timely target monitoring, to ensure the accuracy of the test, to provide more accurate and reliable reference information for clinical diagnosis and treatment.%目的：探究新生儿血培养中出现假阳性原因和应对策略及其应用价值。方法回顾性研究2013年1月～2015年12月新生儿血培养阳性病例，分析假阳性出现的主要原因，并及时地应用相应的对策。结果条件致病菌属于主要的假阳性病例的病原菌；干预前的假阳性率是24.6%，干预后的假阳性率是6.5%，差异有统计学意义（P＜0.05）。结论在新生儿血培养阳性标本中，假阳性病例较多，需要及时地加强目标性监测，确保检验准确度，为临床诊治提供更加准确可靠的参考信息。
