Back story

X73 – Standards Development Update - 2008-01-17

Back story

  • Mapping from X73 information to HL7 v3 …

    • Discussed in the JWG meetings for many years – never any traction

    • Part of the DEV WG Mission when formed 2 years ago +

    • Included in the HL7 – IEEE EMBS MoU

    • CDA representation has motivated the needed participation to move forward on X73 => v3 Mapping and prototyping

    • In IHE, exchange of device information via XDS motivates a CDA-device content profile

    • Anesthesia records – inconsistent & non-comparable device-related information (same parameter name – different measurement methods)

    • Event investigations – detailed device information during and around an adverse event

    • Medical Device Report (MDRs) CDA profile now being discussed

    • … many many more on the horizon!

HL7 DEV WG

HL7 DEV WG Vision

To facilitate integration of health care device information throughout the health care enterprise, enabling more efficient and accurate processing of device-related data and ultimately resulting in improved patient safety and quality of care.

HL7 DEV WG Relationships

Sponsor: Orders & Observations

Coordinating: Vocabulary, Patient Care, CBHS, EHR, GAS

Transitioning: Expert Domain Steering Division

HL7 DEV WG

HL7 DEV SIG Mission

  • To facilitate the integration of health care device information at the enterprise level by:

    • Establishing standardized version 2.x and version 3 messaging profiles to support health care device interoperability at the enterprise level

    • Harmonizing device data models between HL7 and other organizations including ISO/IEEE 11073

    • Harmonizing and coordinating device terminology usage within HL7 components

    • Support revision and harmonization of the Clinical and Laboratory Standards Institute (CLSI – formerly NCCLS) Point of Care Test (POCT) and laboratory automation standards

    • General coordination and harmonization between HL7 and other national and international organizations involved in health care device informatics and interoperability

X73 to v3

X73 – Standards Development Update - 2008-01-17

X73 to v3

  • Mapping from X73 semantics to HL7 v3 …

    • Continuity with v2.x mapping

    • X73 terminology usage

    • Parameter containment information

    • Device Identification & System information

    • Data types: Numerics, enumerations, wave snippets, trends, alarms, etc.

    • Language specific text labeling

    • Key Issues: Level of Detail + Textual Rendering Requirements


Related activities

X73 – Standards Development Update - 2008-01-17

Related Activities

  • Other v3 device oriented projects …

    • Annotated ECG (aECG) / RCRIM for FDA drug study submissions

    • Medical Waveform Encoding Rules (MFER) – CDA

    • Implantable Devices, Cardiac (IDC) workflow

    • Dialysis treatment summary report

    • IHE PCD v3/CDA profiling (incl. KP/Hendler prototyping)

    • Continua reports containing 11073-originated device data


Project planning

X73 – Standards Development Update - 2008-01-17

Project Planning

  • Current HL7 DEV WG plans …

    • Formally initiate a Project to produce a consistent HL7 v3 device representation based on ISO/IEEE 11073 semantics

    • Formally initiate a Project to extend this device information representation to include CDA-based documents

    • Coordinate with IHE PCD and other groups as appropriate to ensure continuity with related projects and activities
