摘　　要：目的调查青海省临床实验室临床基础检验专业急诊标本检验前和实验室内周转时间(TAT)现状,分析TAT超时的影响因素,为实验室质量改进提供依据。方法通过检验医学信息网网络平台向参加2022年青海省临床检验中心室间质量评价的临床实验室发放《2023年临床检验医疗质量控制指标室间质量评价(全年)质评上报表》,要求各实验室统计上报2022年1-12月不同专业急诊标本检验前TAT、实验室内TAT的年中位数和年第90百分位数(P_(90)),根据国家卫生健康委临床基础检验中心和青海省临床检验中心提供的《临检专业2023年临床检验医疗质量控制指标室间质评报告》摘取数据,采用SPSS22.0软件对回报数据的全血、尿液、粪便常规(简称三大常规)和凝血TAT相关信息进行统计分析,统计TAT在不同时间段内的实验室比率及超出阈外值的实验室比率。结果青海省参加该次调查的临床实验室共159家,实验室填报率为100.00%。其中,三级医院、二级医院及二级以下医院分别占16.35%、45.28%、38.36%。调查结果显示青海省临床实验室三大常规急诊标本检验前TAT年中位数、年(P_(90))小于30 min的实验室分别约占72.98%、56.61%,超出阈外值(≥30 min)的实验室占27.02%;实验室内TAT年中位数、年(P_(90))小于30 min的实验室分别约占53.46%、39.00%,超出阈外值(≥30 min)的实验室占46.54%。临床基础检验专业凝血急诊标本检验前TAT年中位数、年(P_(90))小于30 min的实验室分别约占68.35%、52.52%,超出阈外值(≥30 min)的实验室占31.65%;临床基础检验专业凝血急诊标本实验室内TAT年中位数、年(P_(90))小于60 min的实验室分别约占89.21%、74.10%,超出阈外值(≥60 min)的实验室占10.79%。结论青海省临床实验室临床基础检验专业急诊标本检验前和实验室内TAT超出阈外值的实验室较多,部分实验室需要优化标本周转环节,缩短标本TAT,应根�Objective To investigate the current status of pre-examination and intra-laboratory turnaround time(TAT)of emergency specimens in clinical laboratory medicine specialty of clinical laboratories in Qinghai Province,and to analyze the influencing factors of TAT overtime,so as to provide a basis for laboratory quality improvement.Methods“The 2023 external quality Assessment Report of Clinical Laboratory Medical Quality Control Indicators(Annual)”was distributed to the clinical laboratories participating in the 2022 external quality assessment of Qinghai Provincial Center for Clinical Laboratories through the network platform of Laboratory Medicine Information Network.Each laboratory was required to report the median and annual 90th percentile(P_(90))of pre-test TAT and intra-laboratory TAT of emergency specimens in different specialties from January to December 2022.Data were extracted according to the"2023 clinical laboratory Medical quality control indicators external quality assessment report"provided by the National Center for Clinical Laboratories of the National Health Commission and Qinghai Provincial Center for Clinical Laboratories.SPSS22.0 software was used to statistically analyze the whole blood,urine and fecal routines(the three routines)and coagulation TAT related information of the returned data.The proportion of laboratories of whole blood,urine and fecal TAT in different time periods and the proportion of laboratories exceeding the threshold value were counted.Results A total of 159 clinical laboratories in Qinghai Province participated in this survey,and the filling rate was 100.00%.Among them,tertiary hospitals,secondary hospitals and below secondary hospitals accounted for 16.35%,45.28%and 38.36%,respectively.The results showed that approximately 72.98%and 56.61%of clinical laboratories in Qinghai Province had a median and an annual(P_(90))of pre-test TAT less than 30 min in three routine emergency specimens,respectively,and 27.02%of clinical laboratories exceed the threshold value(≥30 min)
