PDCA循环管理法在降低新生儿血培养假阳性率中的应用

Application of PDCA cycle management method in reducing false positive rate of neonatal blood culture

目的：探讨PDCA循环管理法在降低新生儿血培养假阳性率中的应用及临床效果，为指导临床诊断及合理应用抗菌药物提供客观依据。方法：对2010年7一12月新生儿科32例血培养阳性患儿进行目标追踪监测，了解分析假阳性发生原因并采取PDCA循环管理法，比较实施前后新生儿血培养假阳性率。结果：实施前血培养假阳性患儿病原菌分布以条件致病茵为主，实施前后血培养假阳性率比较差异有统计学意义（P〈0．01）。结论：将PDCA循环管理法应用于新生儿血培养阳性目标性监测，可提高血培养标本送检质量，降低假阳性率，保证检验结果准确。

Objective：To explore the application of PDCA cycle management method in reducing false positive rate of neonatal blood euhure and investigate the clinical effect in order to provide objective basis for guiding clinical diagnosis and reasonable application of antibioties. Methods：The target tracking monitoring was conducted to 32 newborns（ born from July to December 2010） whose blood culture was positive to understand and analyze the false positive causes,and the PDCA cycle management method was implemented. The false positive rate of neonatal blood culture was compared before and after the implementation of the PDCA cycle management method. Results ： The con- ditionally pathogenic bacteria in the false positive blood culture was the main pathogen in the distribution before the implementation of the method;the difference in the comparison of the false positive rate of blood culture was statistically significant before and after the implementation of the method （P 〈 0.01 ）. Conclusion：The PDCA cycle management method applied to the target tracking monitoring can improve the quality of blood culture specimens and reduce the false positive rate so as to ensure accurate test results.
