Picture Archiving and Communication Systems (PACS) are expected to replace the currently existing film systems within the decade. However, presently there are no formal measures to evaluate the cost-effectiveness of image management systems. The objective of this Program Project is to develop a methodology to compare the cost-effectiveness of a PACS and the existing film management system. We will measure cost-effectiveness in the Medical Intensive Care Unit, the Emergency Department, and in the outpatient Neurology suite. The effects of diagnostic outcomes on health outcomes will also be estimated. The first project develops and evaluates a model that describes the diagnostic value of an image management system. The model will be validated and tested to determine its predictive capability. The second project evaluates workstations for clinical effectiveness, analyzes the radiologist-referring physician interaction, and studies physician acceptance. Teleconsulting between the radiologist and the referring physician including the transmission of outside images from the referring physician to the radiologist will also be studied. The third project utilizes clinical-history derived rules to optimize the display with diagnostically-relevant information. The fourth project uses the results of the other projects to measure the cost-effectiveness of PACS. Both direct and indirect costs before and after implementing PACS will be combined with data from the diagnostic value model to derive the incremental cost-effectiveness and to compare the usefulness of PACS to other medical interventions. The Operations core is responsible for software development, data collection, and quality control. This Program Project will provide the methodology for other institutions to determine the value of implementing PACS in their environment. Additionally, it may be applicable for the assessment of other medical technologies and to aid in the comparison of investments in such technologies.

图像存储和通信系统（PACS）预计将取代 现有的电影系统。 但是当前 没有正式的措施来评估图像的成本效益 管理系统。 该项目的目标是开发一个 比较PACS和现有PACS的成本效益的方法 电影管理系统 我们将衡量医疗成本效益 重症监护室、急诊室和门诊部 神经科套房。 诊断结果对健康结果的影响 也将被评估。 第一个项目开发和评估一个模型，该模型描述了 图像管理系统的诊断价值。 该车型将 经过验证和测试，以确定其预测能力。 第二 项目评估工作站的临床有效性，分析 放射科医生-转诊医生互动，以及研究医生 验收 放射科医师和转诊医师之间的咨询 包括来自转诊医生的外部图像的传输 医生对放射科医生也将进行研究。 第三个项目 利用临床历史导出的规则来优化显示， 诊断相关信息。 第四个项目使用结果 的其他项目，以衡量PACS的成本效益。 两 在实施PACS之前和之后的直接和间接成本将 结合来自诊断价值模型的数据， 增加成本效益，并比较PACS的有用性， 其他医疗干预。 运营核心负责 软件开发、数据收集和质量控制。 该计划项目将为其他机构提供方法， 确定在其环境中实施PACS的价值。 此外，它可能适用于其他医疗评估。 技术，并帮助比较在这种投资 技术.
