缺血性脑血管病患者绿色通道标本周转时间改进与分析

Improvement and analysis of green channel sample turnaround time in patients with ischemic cerebrovascular disease

目的分析缺血性脑血管病患者绿色通道检验标本的周转时间(TAT)等质量指标,以考察绿色通道标本检验路径TAT质量目标的实施效果,为持续改进提供支撑。方法以120例缺血性脑血管病绿色通道患者作为绿色通道组,以相应的普通急诊患者120例作为普通急诊组,统计开具检验申请单、标本采集、标本接收和报告发出4个时间段的TAT;分析各检验指标的阳性率、复检率、TAT超时原因和临床反馈指标。结果 97.5%的绿色通道标本的检测结果均在目标TAT(30min)内发出,绿色通道标本各个时间段的TAT及总TAT均明显高于同时间段普通急诊标本(P<0.05);绿色通道溶栓患者血常规的白细胞阳性率明显高于同时间段其他绿色通道患者(P<0.05);绿色通道溶栓患者的凝血检测结果阳性率明显高于普通急诊患者(P<0.05)。结论该科绿色通道标本的TAT控制取得了较好效果,达到了预定的质量目标,较好地支持了急性脑血管病的临床诊治。

Objective To analyze the quality indicators of turnaround time（TAT）of green channel laboratory sample in the patients with ischemic cerebrovascular disease in order to investigate the implementation effect of TAT quality target of green channel sample laboratory pathway to provide support for continuous improvement.Methods One hundred and twenty cases of ischemic cerebrovascular disease green channel served as the green channel group and the corresponding 120 cases of general emergency as the general emergency group.TAT at 4 time periods of issuing laboratory detection application,sample collection,sample reception and report were performed the statistics;the positive rate,re-detection rate,TAT overtime causes and clinical feed back of various detection indicators were analyzed.Results The detection results in 97.5% of green channel specimens were issued within target TAT（30min）,TAT and total TAT of green channel specimens in various time periods were significantly lower than those of the common emergency specimens at the same time periods（P0.05）.The WBC positive rate of blood routine in the patients with thrombolysis green channel was significantly higher than that in common emergency patients（P0.05）,and the positive rate of coagulation detection results in the patients with thrombolysis green channel was significantly higher than that in common emergency patients（P0.05）.Conclusion The TAT control of the green channel specimens in our department achieves good results,reaches the scheduled quality goal,and better support clinical diagnosis and treatment of acute cerebrovascular disease.
