The broad, tong-term objective of this Program Project Grant is to develop an effective imaging-based information and health care delivery system to support clinical practice, research, and education.
The specific aims of the grant are to: (1) evolve PACS into an effective infrastructure that promotes the objectification of subjective patient clinical symptoms, (2) develop methods for improving the characterization of medical data through structured data collection, natural language processing of medical reports (NLP) and parametric summarization for medical images, (3) provide flexible, patient -specific presentation methods of medical images, timelines, and structured medical data. The objectification, intelligent access, and flexible presentation of medical data provide better information, which will facilitate the evidence-based practice of medicine and enhance research and evaluation. Five integrated projects employ novel techniques to address specific elements of the system. Intelligently selected imaging protocols are used to objectify patient symptoms. Well-defined information units capture and structure diverse forms of data, whether directly or indirectly through NP for text of parametric summarization for images. Patient medical records are correlated with medical literature by content. Timelines organize the data into a format that allow medical events, their dependencies, and conditional trends to be easily visualized (Project 3). Scenario-based proxies provide up-to-date access to relevant medical information. Relaxation broadens queries to medical information when exact matches are not found. Software toolkits and user models enable user-, and domain-, and task-specific customizations. The hardware independent architecture will facilitate access to the system across different platforms and software subsystems. Together, they form a unique infrastructure that provides broad and intelligently customized access to well-defined structured data and up-to-date literature. This, in addition to patient-specific relevant data, expert opinion, and similar cases with known outcome, will promote the evidence-based practice of medicine.

This, in addition to patient-specific relevant data, expert opinion, and similar cases with known outcome, will promote the evidence-based practice of medicine. Evaluation of the impact of the proposed system will focus on technical measures; process of care; and patient and physician satisfaction. The evaluation will also explore the relationship between process changes and specific outcomes, particularly short-term health related quality of life. Although a formal cost-effectiveness study is not proposed, the foundation is laid for these measurements when these PACs technologies mature. These measurements will be facilitated by recording resource utilization, determining of imaging-based episodes of care, and counter- specific information related to a chief complaint.
