品管圈活动对提高血培养阳性率的效果分析

Analysis on effect of quality control circle activities on improving positive rate of blood culture

目的分析品管圈(QCC)活动对提高医院血培养阳性率的效果,为指导临床正确合理应用抗菌药物提供客观依据。方法调查曲靖市第二人民医院的血培养现状,以"提高血培养阳性率"作为活动主题开展QCC活动,分析整个血培养流程存在的问题,拟定对策并实施。绘制柏拉图和雷达图,比较改善前后血培养的查检结果,分析QCC活动的有形成果和无形成果。结果开展QCC活动后的血培养阳性率较活动前明显升高(6.93%比4.03%,P<0.05),目标达成率为108.24%,进步率为72.00%。雷达图显示,QCC活动后圈员的各项QCC能力均有一定程度提升。结论开展QCC活动可改进血培养流程,提高血培养阳性率。

Objective To investigate the effect of quality control circle (QCC) activities in our hospital on elevation of positive rate of blood culture in order to provide an objective basis for clinically using antibiotics correctly and rationally. Methods The present status of blood culture in the Second People's Hospital of Qujing City was investigated, and the QCC activities were conducted to improve the positive rate of blood culture that was the main topic of the activities. The problems existing in the whole process of the blood culture were analyzed and countermeasures were formulated to implement. The Parato diagram and radar chart were drawn, the examination results of blood culture before and after improvement were compared, and the tangible and intangible results of QCC activities were analyzed. Results By improving the quality of blood culture process, the positive rate of blood culture after the improvement was obviously increased comparedwith that before the improvement (6.93% vs. 4.03%, P< 0.05). The target achievement rate was 108.24% and the progress rate was 72.00%. The radar chart showed that the abilities of circle members in various items in the activities had been improved to a certain extent after the QCC activities. Conclusion Through the quality control circle activities, the blood culture process was improved and the positive rate of blood culture was increased.
