The present project is a step by step description of the creation of a computerized surveillance system using historical information derived from automated expert system acquisition. Since historical information is in many cases not sufficient for establishing an individual's medical diagnosis, the accuracy of surveillance is measured against the "gold standard" diagnosis provided by a panel of physicians. It was possible to survey within acceptable limits of accuracy in the conditions of the project. The results reveal a high level of sensitivity by computer surveillance as well as an accurate ability of electronic tracking of disease incidence over a period of time. However, further investigation into the accuracy of electronic surveillance and selection of symptoms used to define a disease should be studied. The feasibility of employing electronic historical medical information to survey disease has potential in providing real-time epidemiological data.
本项目逐步描述了利用从自动化专家系统获取的历史信息创建计算机化监测系统的过程。由于在许多情况下，历史信息不足以确立个体的医学诊断，因此监测的准确性是根据一组医生提供的“金标准”诊断来衡量的。在项目条件下，可以在可接受的准确性范围内进行监测。结果显示计算机监测具有较高的灵敏度，以及在一段时间内准确跟踪疾病发病率的能力。然而，应进一步研究电子监测的准确性以及用于定义疾病的症状选择。利用电子历史医学信息进行疾病监测的可行性在提供实时流行病学数据方面具有潜力。
