BACKGROUND The American College of Surgeons Commission on Cancer (CoC) has conducted national Patient Care Evaluation (PCE) studies since 1976. METHODS Over 1500 hospitals with CoC-approved cancer programs were invited to participate in this prospective cohort study of U.S. thyroid carcinoma cases treated in 1996. Follow-up will be conducted through the(More)
Most healthcare data is narrative text and often not accessible and easy to find at the clinical workstation. XML related standards (XML schema, XForms, XSL, Topic Maps, etc.) provide an infrastructure that might change the situation. Yet, it is up to the application developers to combine the given standards and tools into a running system. The cost of(More)
BACKGROUND To determine current patterns of care and disease characteristics for patients with thyroid carcinoma, a Patient Care Evaluation Study was initiated in 1996 in the U.S. and Germany. This project addresses ongoing concerns with respect to the diagnostic evaluation and treatment of patients diagnosed with thyroid carcinoma and raises questions(More)
OBJECTIVES Data and information in medicine are mainly represented in slightly structured or even unstructured, narrative text documents. It is nearly impossible to detect and handle relationships between data elements within narrative documents or to retrieve parts of documents that contain specific information. But information access and retrieval are(More)
A b s t r a c t With the introduction of ICD-10 as the standard for diagnostics, it becomes necessary to develop an electronic representation of its complete content, inherent semantics, and coding rules. The authors' design relates to the current efforts by the CEN/TC 251 to establish a European standard for hierarchical classification systems in health(More)
The application of XML (Extensible Markup Language) is still costly. The authors present an approach to ease the development of XML applications. They have developed a Web-based framework that combines existing XML resources into a comprehensive XML application. The XML framework is model-driven, i.e., the authors primarily design XML document models (XML(More)
Guidelines in medicine have been proposed as a way to assist physicians in the clinical decision-making process. Increasingly, they form the basis for assessing accountability in the delivery of healthcare services. However, experiences with their evaluation, as the most important step in the continuous guidelines process, are rare. Patient Care Evaluation(More)
Most clinical data is narrative text and often not accessible and searchable at the clinical workstation. We have therefore developed a search engine that allows indexing, searching and linking different kinds of data using web technologies. Text matching methods fail to represent implicit relationships between data, e.g. the relationship between HIV and(More)
Measures are designed to evaluate the processes and outcomes of care associated with the delivery of clinical (and non-clinical) services. They allow for intra- and interorganizational comparison to be used continuously to improve patient health outcomes. The use of performance measures always means to abstract the complex reality (medical scenarios and(More)
With the introduction of the ICD-10 as the standard for diagnosis, the development of an electronic representation of its complete content, inherent semantics and coding rules is necessary. Our concept refers to current efforts of the CEN/TC 251 to establish a European standard for hierarchical classification systems in healthcare. We have developed an(More)
