品管圈在改善急诊生化检验及时率中的应用

Application of quality control circle on timely rate improvement in emergency biochemistry tests

目的用品管圈活动方法提高急诊生化检验及时率。方法成立品管圈小组,分析上海儿童医学中心1年内的急诊生化检验样本周转时间(TAT)的状况,找出不及时原因,制定改进措施并判断效果。结果现况调查得出检验不及时的主要原因为样本高峰期的仪器拥堵、夜班人员晨间样本来不及处理、内部运送不及时、结果异常样本需复查等。通过提高仪器检测速度、检测高峰时段分流样本、优化运送流程、特殊时段合理调配人员、检验信息系统预警等方法缩短急诊生化样本的检测TAT,不及时率从10.73%下降到2.40%。结论品管圈活动对缩短急诊生化检验样本TAT有实际价值,值得临床上推广应用。

Objective To improve the timely rate of emergency biochemistry tests with quality control circle. Methods A quality control circle group was set up, and the data of sample turn-around time （ TAT ） for past 1 year of emergency biochemistry tests in Shanghai Children＇s Medical Center were analyzed. The reason causing TAT retardation was found, in order to draw up solutions to improve TAT status, and the efficiency was assessed. Results For the emergency biochemistry tests, 4 major reasons contributed to TAT retardation： equipment busy at peak time, labor shortage for night-shift persons at morning time, inner sample transfer retardation and time-consuming for re-check of abnormal samples. Accordingly, through improving instrument test speed and sample distribution at peak time, optimizing sample transaction and human resource at specific time period, and pre-waming through laboratory information systems, all solutions could contribute to TAT improvement. The untimely rate reduced from 10.73% to 2.40%. Conclusions The TAT could be saved in clinical laboratories with the application of quality control circle, and it is worth to be adapted in clinical laboratories.
