Interoperability for the NHIN Thomas Jepsen, IEEE-USA MTPC Version 1.3 Updated July 5, 2005
What is Interoperability? Ability of two or more systems or components to exchange information and to use the information that has been exchanged. Source: IEEE Standard Computer Dictionary: A Compilation of IEEE Standard Computer Glossaries, IEEE, 1990
Functional vs. Semantic Interoperability Functional Interoperability: Shared Architectures Shared Methods Shared Frameworks Semantic Interoperability: Shared Datatypes Shared Terminologies Shared Codings Source: IEEE 1073/ISO TC215 WG2.1/CEN TC251 WGIV Point of Care Medical Device Communications
A Real World Model: The Internet/World Wide Web Functional interoperability – browsing/searching/online purchasing work the same, regardless of what browser I use or what operating system my computer uses Semantic interoperability – the functional interoperability of the Internet/WWW relies on the semantic interoperability provided by http, html, xml, etc…
What is NHIN? National Health Information Network Not a physical network, but rather a conceptual network May include information that is not in electronic online format – e.g. legacy paper records May consist of multiple networks with linkages to each other To be built upon existing network technology Part of the nations critical infrastructure
Who May Use NHIN? Healthcare professionals use it to diagnose and treat patients (e.g. telemedicine, home healthcare) Healthcare professionals use it to access/update/transfer electronic health records (EHR) and other personal health information (PHI) Patients use it to access/verify EHR information and other PHI Public health officials use it to broadcast healthcare/epidemiological alerts and healthcare-related information Medical/emergency first responders use it to obtain PHI in emergency situations Healthcare providers and insurors use it to submit/process/pay insurance claims Public health agencies use it to obtain information on quality of healthcare Pharmacists may use it to fill prescriptions electronically

Known Gaps in the Interoperability Picture QOS/Bandwidth Requirements for video transmission – IEEE 802.1ah is working on QOS standards for streaming multimedia over Ethernet Network Reliability – no known standards Need to identify NHIN as part of national critical infrastructure
New Protocols? Standards for lossless imaging? Security Standards? Encryption? Standards for network compatibility? Compatible storage formats? Other Areas for Investigation
Moving Forward… Recommendations for action: Position paper on interoperability – complete by Nov/Dec 2005 White paper on interoperability for greater depth Recommendations/liaisons to standards bodies – IEEE Reliability Society, Critical Infrastructure Committee, 802.1ah Request input from NCHIT, HHS, CDC, FDA, etc. on requirements Other?
