A study on development of perinatal data processing system using microcomputer based local area network.

医疗信息是复杂的，包括离散和连续的时间序列数据，书面信息和测量。为了控制如此海量的信息，电子数据处理系统是必要的。因此，我们开发了一个基于微机的局域网（LAN）来处理与围产期事件相关的围产期信息，并评估了该系统的临床应用。在这个系统中，安装在门诊部和产科病房的六个微型计算机终端机与一个中央控制单位相连。通过使用该系统，所有医务人员都可以在检查期间将数据输入微机终端。数据以实时方式处理，可以随时随地在最近的终端上与先前输入的信息一起反馈到电视显示器上。软件方面，我们为该系统开发了一些应用程序。特别是，为了克服人机界面的困难，在每个终端上都准备了一本几乎包括所有医学术语的词典，并在选择合适的项目后，将输入操作减少到只使用数字键。该系统自1986年6月开始进行临床试验。我们对该系统在医生、病人和机器界面之间的适用性进行了临床评估。所有医务人员经过一小时的培训，使用简单的操作手册即可操作该系统进行日常工作。虽然数据输入比以前平均多花了3分钟，但数据的访问和检索更加可行。与图表上描述的信息相比，计算机记录的数据具有很高的准确性。经过20个月的测试，发现该系统是未来围产期医学应用的可扩展原型。

Medical information is complex and includes discrete as well as continuous ous data in a time-sequence, written information and measurement. In order to control such a large mass of information, and electronic data processing system is necessary. Therefore, we developed a microcomputer based local area network(LAN) to process perinatal information related to perinatal events and assessed this system's clinical use. In this system, six microcomputer terminals, installed at the outpatient department and obstetric ward, were linked to a central control unit. By using this system, all members of the medical staff can enter data into a microcomputer terminal during an examination period. The data is processed in a real time manner amd can be fed back on TV display, anytime and anywhere, at the nearest terminal together with previously entered information. With regard to software, we developed some application programs for this system. Especially, in order to overcome the difficulty of the man-machine interface, a dictionary including almost all medical terms was prepared in each terminal and input operation was minimized to using only numeric keys after selecting an appropriate item. This system has been in clinical test run since June, 1986. We gave a clinical assessment of this system in regard to applicability between doctor, patient and machine interfaces. All medical staff members could operate this system for daily work after one hour training using a simple operating manual. Although data input takes an average of 3 minutes longer than before, access and retrieval of data is more feasible. Compared to information described on charts, there is a high level of accuracy of data recorded by computer. When tested over a 20-month period, this system was found to be an extensible prototype for application in future perinatal medicine.
