KNOWLEDGE BASED RADIOLOGY INFORMATION SYSTEM

这个项目的目标是提高测量的准确性。 放射科医生解释X光检查。二 将研究以计算机为基础实现这一目标的方法。第一个a 将进行计算机生成的针对患者的咨询 在放射科医生看X光的时候是可用的。会的 由一份简短的临床总结组成，其要素是为 它们的信息内容，包括 患者1到5种最可能的疾病，以及提示列表 表明那些异常的X光发现会导致 最重要的是诊断病人。第二种技术 调查将是计算机管理的、持续的审计 将使用每个患者的出院诊断来帮助确定 X射线解译的平均准确度。这 机制可以向个别放射科医生提供反馈 关于特定的疾病和他们的研究结果 读数并不理想。 将通过比较胸部x线进行评估。 在咨询/提示的情况下和不使用咨询/提示时生成的解释 系统。将使用两种方法。第一个将比较所有 在实施前12个月内进行的检查 那些来自实施后类似时期的。第二 将评估对200个精选胸部X-的解释的差异- 六位医生在会诊和不会诊的情况下对射线进行了解读 和提示符。在这次测试中，一个专家小组将确定 出现了实际的异常。所收集到的对 将使用200部电影来测试审计系统，以确定 它的结果是否与传统的 基于重读多张x光片的性能测量。 在此项目期间创建的应用程序将使用Expert 帮助系统中的系统工具与一组 知识管理例程。该项目的隐含目标 是研究信息论在信息领域的应用 放射科的准确性问题。这些工具 将在医学上有普遍的适用性。

The goal of this project is to improve the accuracy of the radiologist as he/she interprets x-ray examinations. Two computer-based approaches to this goal will be studied. First a computer-generated, patient-specific consult will be made availabe to the radiologist at the time he reads the x-ray. It will consist of a brief clinical summary whose elements are chosen for their information content, a differential diagnostic list containing the patients 1 to 5 most likely diseases, and a list of prompts indicating those abnormal x-ray findings that would contribute the most to diagnosing the patient. The second technique investigated will be a computer-managed, continuous audit that will use the discharge diagnoses of each patient to help determine the average accuracy of the x-ray interpretations. This mechanism can provide feedback to the individual radiologists concerning the specific diseases and findings for which their readings are suboptimal. Evaluation will be through comparison of the chest x-ray interpretations generated with and without the consult/prompt system. Two approaches will be used. The first will compare all examinations from a 12-month period before implementation with those from a similar period after implementation. The second will assess the difference in interpretations on 200 select chest x- rays interpreted by six physicians with and without the consult and prompts. For this test, an expert panel will determine the actual abnormalities present. The collected interpretations of the 200 films will be used to test the audit system to determine whether its results conform with the results of traditional measures of performance based on rereading multiple x-rays. The applications created during this project will use the expert system tools in the HELP system combined with a group of knowledge management routines. An implicit goal of the project is to investigate the application of information theory to the problem of accuracy in the radiology department. These tools will have general applicability in medicine.
