COMPUTER BASED CLINICAL DECISION ANALYSIS

这项工作的总体目标是使用基于计算机的决策逻辑来 协助执业医师正确运用医学知识。我们 将使用患者特定的决策分析来推荐最佳诊断 以及疑似冠状动脉患者的治疗程序 疾病。使用医疗决策帮助系统，我们有 构建用于计算特定患者的模块化决策逻辑 几种可供选择的结果中每一种都会产生的概率。逻辑 还存在计算与这些可能的每一种情况相关联的实用程序的方法 结果状态。除了开发逻辑，这将增强 目前的分析能力，我们计划通过以下方式评估系统 在六名为冠心病患者看病的医生的办公室里使用它 动脉疾病。 我们还建议开发和使用基于计算机的逻辑来诊断 肺部疾病。提供有关放射学的详细描述 在决策逻辑中需要的发现，放射科医生将与 直接与计算机终端连接。作为这种交互的结果， 放射科医生将从 全面的临床数据库，是帮助系统的一部分。这个 放射科医生认为，这些信息将使他们能够更有效地 解释放射学的发现并担任顾问。

The overall goal of this work is to use computer-based decision logic to assist the practicing physician to appropriately use medical knowledge. We will use patient specific decision analysis to recommend optimal diagnostic and therapeutic procedures for patients with suspected coronary artery disease. Using the HELP system for medical decision making, we have constructed modular decision logic for calculating patient specific probabilities that each of several alternative outcomes will result. Logic also exists to calculate the utility associated with each of these possible outcome states. In addition to developing logic which will enhance the capabilities of the present analysis, we plan to evaluate the system by using it in the offices of six physicians who see patients with coronary artery disease. We also propose to develop and use computer-based logic for diagnosing pulmonary diseases. To provide the detailed descriptions of radiological findings which are needed in the decision logic, radiologists will interact directly with a computer terminal. As a result of this interaction, the radiologist will receive additional clinical information from the comprehensive clinical database which is part of the HELP system. The radiologists feel that this information will allow them to more effectively interpret radiology findings and act as consultants.
