1 IHE PCD Rosetta Update Paul Schluter, PhD, GE Healthcare IHE PCD F2F at ECRI, Plymouth Meeting, PA October 20, 2010

2 IHE PCD Rosetta Update October 20, Topics Overview of RTM New: Vendor_VMD  ContainedBy (version ‘3n’) Next: LOINC terms for Infant Hearing Screening Next: RTM Ventilator (work in progress) Also: Begin to compile RTM for events Also: Specify cardinality (for event content models) Also: RTM for PHD devices (Continua V1.5 WAN)

3 IHE PCD Rosetta Update October 20, IHE PCD Rosetta Terminology Management Vendor Terms RTM 1400 rows Harmonized Terms hRTM 440 terms ISO/IEEE Semantic Standards Vendor A Vendor B Vendor C HL7 V2 Message s HL7 V3 CDA/CC D PnP Comm Vendor Semantics IHE PCD TF Content Open consensus process Observation identifiers and co-constraints New terms incorporated into standards hRTM used for conformance testing

5 IHE PCD Rosetta Update October 20, New Vendor_VMD  ContainedBy Specifies VMD / CHAN OBX hierarchy above METRIC VMDVMD required, CHAN not specified VMD / [CHAN] VMD required, CHAN optional [default value] VMD / CHAN VMD and CHAN required Multiple VMD / CHAN combinations may be listed VMD is required for PCD-01 RTM now has ~30 VMDs for GE numeric parameters CHAN also provided for NIBP episodics and infusion channels Now awaiting input from other vendors!

6 IHE PCD Rosetta Update October 20, Next Support LOINC terms and mapping Add RTM column for LOINC observation identifiers for Infant Hearing Screening observation IDs Enumerated LOINC values in Enum_Values with ^LOINC Clem McDonald’s MDC to LOINC mappings (NIST RTMMS)

7 IHE PCD Rosetta Update October 20, Next RTM Respiratory and Ventilator New ventilator and gas measurement terms New gas measurement terms incorporated into RTM ‘3m’ Current focus is ventilator mode and breath annotations Informal collaboration between IHE PCD and IEEE and members of ASTM F2761 (ICE), IEC SC62A WG5, ISO IHTSDO, ISO TC215 WG7 and HL7 Health Care Devices SIG, led by Norman Jones and Jan Wittenber. Making excellent progress on ‘ventilator mode’ modelling!

8 IHE PCD Rosetta Update October 20, Also Event identifiers and content models ACM Alarm Reporters should begin to compile: Event and alarm identifiers and key properties numeric alarm or ‘pattern’ alarm (e.g. ‘asystole’) timepoint or interval event physiologic and/or technical Content models (including cardinality) infusion pump parameters related to an event Let’s start capturing this information!

9 IHE PCD Rosetta Update October 20, Also RTM for PHD over Continua WAN Capture Continua V1.5 WAN Guidelines for ISO/IEEE PHD (Personal Health Devices) in machine readable RTM format Similar format to RTM … but reflects origin from ISO/IEEE and 104xx PHD specializations, as mapped to Continua WAN interface based on IHE PCD-01 TF. Captures the following information: REFIDOBX-2OBX-3OBX-4 MDC_DEV_SPEC_PROFILE_BLD528391^MDC_DEV_SPEC_PROFILE_BP^MDC1..

11 IHE PCD Rosetta Update October 20, Semantic Interoperability Scenario: Convey near real-time medical device data -from device to device or system -from device to enterprise using a gateway -enterprise document exchange Objective: Communicate medical device data using a single unified nomenclature and semantic model that can be rigorously defined and enforced to facilitate safe and effective plug-and-play interoperability.

12 IHE PCD Rosetta Update October 20, Related RTM and hRTM Initiatives Respiratory and Ventilation extensions (current) -An informal collaboration between IHE PCD and MDC and members of ASTM F2761 (ICE), IEC SC62A WG5, ISO IHTSDO, ISO TC215 WG7, and HL7 HCD. See XML publication format for nomenclature extensions Annotated ECG (aECG) Implanted Device Cardiac (IDC) Joint IHE and Continua WAN interface -RTM and RCH (Rosetta Containment Hierarchy) for IEEE Std and personal health devices, as Continua deliverables for HITSP RMON SDE#2. NIST HL7 V2 and IEEE Message Conformance Testing

13 IHE PCD Rosetta Update October 20, Device Device Intermediary Device EHR or Care Coordination Applications Home Setting Hospital Setting Device Intermediary IHE DEC over MLLP SDE #2: IHE DEC over WS* IHE and Continua WAN (HITSP RMON SDE #2) IHE DEC: Same protocol used in two settings … SDE #1 SDE #3+

14 IHE PCD Rosetta Update October 20, Discussion Unified semantics and semantic model are essential prerequisites for safe and effective interoperability between devices and systems. The hRTM is based on the ISO/IEEE standards and leverages and extends that work by using an open consensus process. For each observation identifier, the hRTM specifies the units-of- measure, enumerated values, measurement sites and other co- constraints. The hRTM rigorously defines what may be sent and informs recipients of what they may expect to receive. The hRTM supports message conformance testing frameworks that can be used for both clinical and personal health devices.
