Recent advances in laboratory information systems have largely been focused on automation. However, the phlebotomy services have not been completely automated. To address this issue, we introduced an automated reception and turnaround time (TAT) management system, for the first time in Korea, whereby the patient's information is transmitted directly to the actual phlebotomy site and the TAT for each phlebotomy step can be monitored at a glance.
The GNT5 system (Energium Co., Ltd., Korea) was installed in June 2013. The automated reception and TAT management system has been in operation since February 2014. Integration of the automated reception machine with the GNT5 allowed for direct transmission of laboratory order information to the GNT5 without involving any manual reception step. We used the mean TAT from reception to actual phlebotomy as the parameter for evaluating the efficiency of our system.
Mean TAT decreased from 5:45 min to 2:42 min after operationalization of the system. The mean number of patients in queue decreased from 2.9 to 1.0. Further, the number of cases taking more than five minutes from reception to phlebotomy, defined as the defect rate, decreased from 20.1% to 9.7%.
The use of automated reception and TAT management system was associated with a decrease of overall TAT and an improved workflow at the phlebotomy room.
实验室信息系统的最新进展主要集中在自动化方面。然而，静脉采血服务尚未完全实现自动化。为解决这一问题，我们在韩国首次引入了自动化接待和周转时间（TAT）管理系统，通过该系统患者信息可直接传输至实际静脉采血点，且每个采血步骤的TAT一目了然。
2013年6月安装了GNT5系统（韩国Energium有限公司）。自动化接待和TAT管理系统自2014年2月起投入使用。自动化接待机器与GNT5的整合使得实验室订单信息无需任何人工接待步骤即可直接传输至GNT5。我们将从接待到实际采血的平均TAT作为评估系统效率的参数。
系统投入使用后，平均TAT从5分45秒降至2分42秒。排队患者的平均数量从2.9人降至1.0人。此外，从接待到采血用时超过五分钟的病例数（定义为缺陷率）从20.1%降至9.7%。
使用自动化接待和TAT管理系统可降低总体TAT，并改善静脉采血室的工作流程。
