Application of specimen turnaround time in laboratory management
-
摘要: 目的:通过研究影响标本周转时间(TAT)的原因,探讨在实验室管理过程中优化TAT的措施,更好的优化患者检验流程,提高检验效率及实验室的管理水平。方法:利用实验室信息系统(LIS)采集2017年1至12月西安交通大学第一附属医院检验科使用同一检测系统血、尿、粪便常规,生化、血凝、免疫检测项目的TAT数据,采用SPSS 13.0软件对不同检测项目的各节点时间分布以及检验人员工作效率数据对TAT的影响进行统计分析。结果:血、尿、粪便常规,生化、血凝、免疫检测项目TAT基本符合科室质量目标要求,门诊患者TAT明显小于住院患者。检验流程中样本接收处理、检测、审核节点时段集中以及不同人员工作效率存在差异现象(P=0.198)是导致TAT延迟的重要原因。结论:改进样本处理手段,优化检验流程,提高工作人员工作效率以及采用自动分检和审核系统可以有效缩短TAT。Abstract: Objective:To explore the measures of optimizing TAT by studying the reasons that affect the specimens turnover time(TAT),in order to optimize the examination process of the patients and improve the examination efficiency and the laboratory management level.Method:The laboratory information system(LIS)was used to collect the TAT data of blood,urine,stool,biochemical,immunoassay and coagulation tests using the same detection system from January to December 2017.The TAT node distributions of different tests and the effect of the work efficiency of the inspectors on the TAT were analyzed by SPSS 13.0 software.Result:The TAT of blood,urine,stool,biochemical,immunoassay and coagulation tests met the requirements of laboratory quality,but the TAT of outpatients was significantly lower than that of inpatients.The node concentration for the sample receiving processing,detection and audit,and the difference of work efficiency among different people were important reasons for the delay of TAT.Conclusion:Improving sample processing,optimizing inspection process,improving staff efficiency,and adopting automatic sample sorting system and audit system can effectively shorten TAT.
