We describe a microcomputer-based clinical laboratory data acquisition system linked with a minicomputer-based patient data management system and report on its performance. The system consists of a microcomputer and six laboratory analyzers: a blood gas analyzer, a flame photometer, a plasma osmotic pressure meter, a chloride ion titrator, a blood sugar analyzer, and a hemoglobin concentration and saturation meter. With the addition of a previously developed microinterface unit to each laboratory analyzer, data from each analyzer can be automatically transmitted to the microcomputer through a communication network. These data are then automatically transmitted to the patient data management system and thereby become part of that data base. Performance of this system was evaluated in two ways: (1) by comparing the turnaround time from an anesthetist's order for a laboratory analysis to receipt of the analysis with the time required in a control situation and (2) by comparing the number of steps a laboratory technician is required to walk to obtain and deliver the laboratory result with the number of steps required in a control situation in which no system was used. The turnaround time and the number of steps walked using this system were 552 +/- 41 seconds (n = 19, P less than 0.001) and 197 +/- 31 steps, respectively (n = 19, P less than 0.001), contrasted with 622 +/- 52 seconds and 374 +/- 87 steps without the system.
我们描述了一种基于微型计算机的临床实验室数据采集系统，该系统与基于小型计算机的患者数据管理系统相连，并报告了其性能。该系统由一台微型计算机和六台实验室分析仪组成：一台血气分析仪、一台火焰光度计、一台血浆渗透压计、一台氯离子滴定仪、一台血糖分析仪以及一台血红蛋白浓度和饱和度计。通过在每台实验室分析仪上添加一个先前开发的微型接口单元，各分析仪的数据能够通过通信网络自动传输至微型计算机。这些数据随后会自动传输至患者数据管理系统，从而成为该数据库的一部分。该系统的性能通过两种方式进行评估：（1）将麻醉师下达实验室分析指令至收到分析结果的周转时间与对照情况下所需时间进行比较；（2）将实验室技术人员获取并交付实验室结果所需行走的步数与未使用系统的对照情况下所需步数进行比较。使用该系统时的周转时间和行走步数分别为552±41秒（n = 19，P＜0.001）和197±31步（n = 19，P＜0.001），而未使用该系统时分别为622±52秒和374±87步。
