MODELING AND EVALUATING IMAGE MANAGEMENT SYSTEMS

该计划项目的目标是开发一种量化的 图片临床效果的客观评价模型 存档和通信系统(PACS)。 诊断准确性、效率、满意度、成本和选择 结果将在三个临床地点进行前瞻性衡量： 急诊科、内科重症监护室和外科 重症监护室。数据采集周期的迭代设计 穿插干预措施是为了促进对 日新月异的技术。 第一个项目开发了一个诊断价值的索引，该索引结合了 诊断的准确性和信息获取的效率。 通过使用观察员协议估计精度的方法将是 学习。该指数将作为有效性分析的一部分。 第二个项目研究不同的PACS实施如何影响 病人护理的有效性。数学模型将是 开发用于模拟诊断成像和信息传递 进程。这些模拟将提供有关运行的数据 在假设情况下的PAC，并将有助于识别机会 以求改进。 第三个项目研究了PACS工作站在医院中的有效使用 临床环境。它将专注于及时收购 报告和图像。 第四个项目开发了一个用于临床评估的模型 和PACS的经济成果。这个项目将把 其他项目的有效性衡量标准，并将其整合到 一种成本效益模型。 这些项目不仅将提供有关PACS的有用信息，而且 也是一种评估快速涌现的信息的模型方法 基于技术的。

The goal of the Program Project is the development of a quantitative model for the objective evaluation of the clinical impact of picture archiving and communication systems (PACS). Diagnostic accuracy, efficiency, satisfaction, cost, and selected outcomes will be measured prospectively at three clinical sites: an emergency department, a medical intensive care unit, and surgical intensive care unit. An iterative design of data collection cycles interspersed with interventions is used to facilitate the evaluation of a rapidly changing technology. The first project develops an index of diagnostic value that combines diagnostic accuracy and the efficiency of information acquisition. Methods of estimating accuracy by using observer agreement will be studied. The index will be part of the effectiveness analysis. The second project studies how various PACS implementations influence the effectiveness of patient care. Mathematical models will be developed to simulate the diagnostic imaging and information delivery process. The simulations will provide data about the operation of the PACS under hypothetical situations and will help identify opportunities for improvement. The third project studies the effective use of PACS workstation in a clinical environment. It will concentrate on the timely acquisition of reports and images. The fourth project develops a model for the evaluation of the clinical and economic outcomes of PACS. This project will bring together the effectiveness measures from the other projects and integrate them into a cost-effectiveness model. These projects will provide not only useful information about PACS but also a model methodology for evaluating a rapidly emerging information based technology.
