Session Title: Terminologies, Information Models and Metadata in Healthcare
The modern approach to analysis and design begins with a formal model of the domain (the information model) and then proceeds to develop corresponding implementation specific and technology specific models. One of the advantages of the is approach is that, to a large extent, the information model provides the necessary definitions and structure of the relevant domain terminology. The terminology of the information model then serves as the foundation for both the structure and content of the actual software implementations. Prior to this, system development tended to start directly at the implementation phase without the benefit of a reference information model and terminology for the domain. One of the major uses for metadata repositories to date has been the integration and translation of 'legacy' implementations into the structure and terms of a shared information model.
The Healthcare domain faces an additional challenge above and beyond the integrating of existing implementations. Much of the “modeling” effort in the Healthcare domain took place many years or even centuries before the advent of electronic computers. These pre-existing models come in the form of coding and classification systems developed to facilitate the acquisition and analysis of large amounts of data in a paper-based environment. Many of systems are still widely used in the healthcare practice of today, frequently in roles other than those that they were designed for.
This session describes how these coding and classification systems came to be what they are today, what they are used for, some of the the unique challenges that they present when it comes to sharing healthcare information, and emerging solutions to these challenges.

Session Title:
Two presentations will be given, one that describes a metadata registry called the United Status Health Information Knowledgebase and one that describes current efforts in the U.S. Government to designate and use healthcare standards and how metadata registries will be used to support this effort.
10:30 - 11:15 AM - United States Health Information Knowledgebase
Director, e-Business Architecture e-Business Policy and Standards Information
Management,
Technology and Re-engineering, TRICARE Management Activity,
Office Assistant Secretary of Defense, Health Affairs
The United States Health Information Knowledgebase (USHIK) is a metadata project to build, populate, demonstrate, and make available for general use a data registry to assist in cataloging and harmonizing data elements across multi-organizations. It is a collaborative effort between the U.S. government agencies such as the Department of Health and Human Services/Centers for Medicare & Medicaid Services (CMS), Department of Defense (DoD)/Health Affairs (HA), Department of Veteran Affairs, and ANSI Standards Development Organizations such as the National Council For Prescription Drug Programs (NCPDP), Accredited Standards Committee, Health Care Task Group (X12), Health Level Seven (HL7), American Society for Testing and Materials Committee E31 on Healthcare Informatics (ASTM E31) and the Medical Device Communications Industry Group (IEEE 1073). The USHIK will be publicly available and managed by Health Informatics Standards Board (HISB). The presentation will provide an overview its capabilities and lessons learned during its development.

Office Assistant Secretary of Defense, Health Affairs
This presentation will describe 1) efforts within the U.S. Government to adopt federal health information interoperability standards for health data segments such as, but not limited to clinical documentation; orders and results including laboratory, radiology, pharmacy; physical examinations; and procedures and 2) how metadata registries will used to support these activities.

Session Title: The NCICB Cancer Informatics Infrastructure Backbone
The National Cancer Institute Center for Bioinformatics (NCICB) mission includes the development of infrastructure that supports the diverse life science domains critical to success in cancer research. This infrastructure can serve as a "backbone" supporting the major larger enterprise of informatics development that must take place throughout academic, government, and commercial research laboratories.
It is clear that there will not be one standard, or one approach to standards. As such, the NCICB is working to develop a "standards stack" within the cancer research community that integrates controlled vocabularies (and their related ontologies), common data elements, and logical models of elements within each domain. NCICB has developing an open source infrastructure to integrate the domain object models (caBIO), the standards based repository (SBR) and the enterprise vocabulary services (EVS) .
NCICB supports a broad initiative to standardize the data elements used in clinical trials data capture and reporting using the ISO11179 standard for metadata. These Common Data Elements (CDEs) are developed by various NCI-sponsored clinical trials organizations, and the data is then centrally stored and managed at NCICB in our Repository.
2:00
– 2:45 PM, caCORE: Common Vocabulary, Metadata, And Object
Models for Cancer Informatics
Peter Covitz
National Cancer Institute
An introduction to caCORE, the NCI Core Infrastructure backbone. caCORE consists of caBIO, a biomedical domain object model and API; caDSR, the cancer data standards repository; and EVS, enterprise vocabulary services. A description of the architecture and services will be presented with an emphasis on the caDSR, an ISO 11179-based initiative to standardize the data elements used in cancer research data capture and reporting.
4:00
– 4:45 PM, LDAP as a Web-Based Mechanism for Metadata Terminology
Publishing and Distribution
Harold Solbrig, Technical Specialist
Mayo Clinic
The Lightweight Directory Access Protocol (LDAP) is a proven technology which is widely used on the web today for publishing addresses and organizational structures. The LDAP design, however, is quite generic, and is potentially useful in situations that are typified by hierarchically organized, write-mostly information. Mr. Solbrig describes how their group has used LDAP to integrate, publish and healthcare-related terminologies and metadata.
