Clinical laboratories are selecting total solutions to point-of-care test (POCT) by handling all aspects of information management ranging from the ordering of the test to the reporting of verified results. Today, many POCT devices can be directly connected to the laboratory information system (LIS) via data management system (DMS). We report here our experience with the networking of POCT glucometers.
We set up computerization of POCT glucometer (Precision PCx, Abbott, USA) in August, 2004 and established a quality control (QC) system for the portable glucometers on 16 wards in Chung-Ang University Hospital. Precision of the glucometers was assessed by performing 28 replicate tests using quality control specimens containing 5 different glucose concentrations. Turnaround time (TAT) was calculated from the data of 17,796 glucose tests performed during a 5-month period in 2004 before computerization of the glucometers and 31,513 tests performed during the same 5-month period of 2005 after computerization.
In the precision study, within-run and total-run CVs were within 10%. With the networking of POCT glucometers, the TAT from the collection of specimen to the specimen receipt to the LIS was 28.5+/-17.2 min compared to 43.6+/-17.5 without the networking (P<0.0001). A staff satisfaction survey received a high score (88%) for an overall satisfaction.
This device significantly expands the data management and networking capabilities of the bedside glucometer. Networking technology should allow for a centralized quality control management.
临床实验室正在通过处理从检测订单到已核实结果报告的信息管理的各个方面,来选择即时检验(POCT)的整体解决方案。如今,许多POCT设备可通过数据管理系统(DMS)直接连接到实验室信息系统(LIS)。我们在此报告我们在POCT血糖仪联网方面的经验。
我们于2004年8月实现了POCT血糖仪(美国雅培公司的Precision PCx)的计算机化,并在中央大学医院的16个病房建立了便携式血糖仪的质量控制(QC)系统。使用含有5种不同葡萄糖浓度的质量控制标本进行28次重复检测,以评估血糖仪的精密度。周转时间(TAT)根据2004年血糖仪计算机化之前5个月期间进行的17796次葡萄糖检测数据以及2005年同一5个月期间计算机化之后进行的31513次检测数据来计算。
在精密度研究中,批内和批间变异系数(CV)均在10%以内。通过POCT血糖仪联网,从标本采集到标本接收再到LIS的TAT为28.5±17.2分钟,而未联网时为43.6±17.5分钟(P<0.0001)。一项员工满意度调查的总体满意度得分很高(88%)。
该设备显著扩展了床边血糖仪的数据管理和联网能力。联网技术应能实现集中质量控制管理。
