DICOM and ISO/TC215 Hidenori Shinoda Charles Parisot

Scope of ISO/TC215 Formed in January, 1998 Standardization in the field of information for health, and Health Information and Communications Technology (ICT) to achieve compatibility and interoperability between independent systems. Also, to ensure compatibility of data for comparative statistical purposes (e.g. classifications), and to reduce duplication of effort and redundancies.

Organization TC215 WG1: Health records and modeling coordination WG 2: Messaging and communication Direct Liaison with DICOM Strategic Committee WG 3: Health concept representation WG 4: Security WG 5: Health cards AHGs: Consumer Policies E-Pharmacy Mobile Health

What ISO/TC215 would try to cover? Country Border Secure Message Transfer Health Indicators and Statistics Electronic Prescription EPR System Interface Certification

WG1: Health records and modeling coordination Scope Standards for the Trusted Management of Information Concerning Health and Healthcare Process Health Record Standards Health Information Modeling Current Work Items Country Identifier Mechanism in Healthcare Requirements for an Electronic Healthcare Record Reference Architecture Health Indicators Conceptual Framework

WG2: Messaging and Communication Scope of Effort Defined in: A General Statement of the Types of Standards to Be Considered The Specific Domains of Activity A Set of Additional Tasks or Working Principles that Will Guide the Effort Specific Domains Clinical Messaging Medical Device Communication Business and Financial Messaging Current Work Items Point-of-Care Medical Device Communication Related Items Method for the Development of Messages Key Characteristics for Interoperability and Compatibility in Messaging and Communication Standards

WG3: Health Concept Representation Scope Standards for the Representation of Health Concepts Formal Models of Representation and Description of Health Concepts Principles of their Organization within Terminologies and their Related Systems Issues Concerning the Context of their Use in Electronic Health Record Current Work Items Vocabulary on Terminological Systems Controlled Health Vocabularies – Vocabulary Structure & High-Level Quality Indicators Integration of a Reference Terminology Model for Nursing

WG4: Security Scope Technical Measures to Protect and Enhance the Confidentiality, Availability, and Integrity of Health Information Accountability for Users Guidelines for Security Management in Healthcare Current Work Items Public Key Infrastructure Directory Services for Security for Communications and Identification of Professional and Patient Security requirements for Archiving and Backup – Archiving of Health Record

WG5: Health Cards Scope Healthcare Usage of Machine Readable Cards Technology Independent Data Structures Leading to Interoperability and Compatibility Identification for Patients and Healthcare Providers Patient Data Cards to Convey Healthcare Data Set Current Work Items Patient Healthcare Data Health Cards – General Characteristics Machine Readable Cards – Health Care Applications – Numbering System and Registration Procedure for Issuer Identifiers

Brief History of Interaction between DICOM and ISO/TC215 TC215 decided not to establish an imaging WG at Berlin meeting in ISO/TC 215 established a peer liaison with DICOM Close cooperation established and now have a yearly joint meeting between DICOM WG10 and TC 215 WG2 DICOM has agreed to respond to TC215's interest to standardize the means for referring images from EPRs.

Pilot Projects DICOM and ISO agreed to begin a pilot project to attain an ISO status to DICOM standard. ISO has a process of approving standards developed by the third standard development organizations (SDOs) as ISO standards. IEEE already started to use this process for Point-of-Care devices. HL7 started this pilot process for gaining ISO standard status for HL7 V2.4.

Next Steps DICOM plans to: negotiate with ISO/TMB (Technical Management Board) to start the pilot project, obtain approval of DICOM 2002 by ISO/TC215 also discuss an specification for referring medical images in EPR.

Conclusion ISO/TC 215’s main role is to facilitate the consolidation of existing standardization efforts such as IEEE, CEN, HL7 and DICOM DICOM has a responsibility of developing international Medical Imaging and Communications Standards and jointly harmonizing them with other healthcare standards with TC215.
