常规生化检验报告周转时间的临床调查分析

Clinical investigation and analysis of turn-around time of routine biochemical test report

目的对检验科常规生化检验报告结果周转时间(TAT)延长的原因进行调查分析,提出改进措施,优化检验结果报告流程,缩短各阶段TAT。方法收集2020年3月于曲靖市第二人民医院就诊进行生化检查的646例门诊和住院患者的实验室检查资料,分类统计申请至采样时间(TAT1)、采样至样本接收时间(TAT2)、样本接收至报告审核时间(TAT3)、报告审核至打印时间(TAT4);比较不同阶段TAT在总TAT中的占比。结果总TAT中位数为1030 min(约17 h),平均1291 min;其中TAT1、TAT2、TAT3、TAT4的中位数分别为614、117、255、44 min,TAT目标值分别为1358、180、361、169 min,均值分别为753、108、246、184 min,分别占总TAT的58.3%、8.4%、19.1%、14.2%。实验室外的TAT(TAT1+TAT2+TAT4)为1045 min,占总TAT的80.9%;实验室内TAT(TAT3)占19.1%。结论影响检验科样本TAT的主要因素在实验室外,应采取措施缩短TAT,提高患者和临床医师的满意度。

Objective To investigate and analyze the reasons for the delay of turn-around time(TAT)of routine biochemical test reports in clinical laboratory,put forward improvement measures and optimize the reporting process,so as to shorten TAT in each stage.Methods The laboratory test data of 646 outpatients and inpatients who had biochemical examination in Qujing Second People's Hospital in March 2020 were collected,and the application to sampling time(TAT1),sampling to sample receiving time(TAT2),sample receiving to report review time(TAT3)and report review to printing time(TAT4)were classified and discussed.The proportion of TAT in each stage was compared.Results The median of total TAT was 1030 minutes(about 17 hours),with average of 1291 minutes;the medians of TAT1,TAT2,TAT3 and TAT4 were 614,117,255 and 44 minutes,TAT target values were 1358,180,361 and 169 minutes,with the average of 753,108,246 and 184 minutes,and accounting for 58.3%,8.4%,19.1%and 14.2%of total TAT.The sample TAT outside laboratory(TAT1+TAT2+TAT4)accounted for 80.9%of total TAT,while the TAT in laboratory(TAT3)accounted for 19.1%of total TAT.Conclusion The main factors influencing routine biochemical TAT are outside laboratory,and measures should be taken to shorten TAT and improve the satisfaction of patients and clinicians.
