Justification

The ISO/IEEE 11073 and IHE PCD technical framework (esp. the Device to Enterprise Communication (DEC) profile) standardize on an IEEE EUI-64 identifier for unique identification of medical devices. This identifier is used extensively in the equipment world - for example, MAC addresses used for Internet connections are based on the same company identifier. The specific HL7 message fields that are specified to convey this information in the IHE PCD DEC profile include MSH-3, OBR-2, OBR-3 and OBX-18.

Description

An EUI-64 consists of a 24-bit company identifier (also known as an Organizationally Unique Identifier, OUI-24) + a 40-bit extension identifier assigned by the company. This 64-bit / 8 byte value may be communicated in binary form, but for the purposes of its used in HL7 is conveyed using its most common ASCII HEX form. For example, "AABBCC1122334455". [See http://standards.ieee.org/regauth/oui/tutorials/EUI64.html for a detailed explanation of the format.]

ValueDescriptionComment
EUI-64IEEE 64-bit Extended Unique Identifier: 24-bit company identifier + 40-bit instance identifier. Typically formatted as 8 HEX digits, for example, “AABBCC1122334455”. The 24-bit Organizationally Unique Identifier (OUI-24) or company identifier is guaranteed to be globally unique. The 40-bit extensions are assigned by manufacturers. This identifier is often used in equipment interfaces (e.g., a “MAC” address).OUI-24 values are administered by the IEEE Registration Authority.
