1. Patient Care Device Interoperability Standards
IHE-PCD
Patient Care Device Interoperability Standards

2. State of open standards-based medical device connectivity?
Nonexistent!
Proprietary Interfaces + Partnerships =
Security for vendors
Limitations & expense for providers & patients
A business issue – not a lack of technology

3. What has blocked implementation of medical device interoperability?
Incomplete standards … but no longer the case!
Uncoordinated & inconsistent demand from providers and other user stakeholders
Undefined stakeholder value propositions
Resources – esp. of standardization efforts
Infrastructure is a hard sell (who benefits?!)
A business issue – not a lack of technology

4. Enterprise Integration
(HL7, DICOM, X12,…X73)
Dialysis Machine
Vital Signs Monitor
LAB
Vent
Pharmacy
CIS
Pulse Ox
Infusion Pumps
Device Data Manager
Gateway
PACS
PoC Integration (X73)
HIS
Multi-vendor environment Requires both semantic & technical interoperability

5. IHE Patient Care Devices Domain

EMBS 1073
CEN
TC251 WGIV
HL7
DEV SIG

6. ISO/IEEE purpose:
Provide real-time plug-and-play interoperability for patient-connected medical devices
and
Facilitate the efficient exchange of vital signs and medical device data, acquired at the point-of-care, in all health care environments
…leveraging off-the-shelf technologies, scaling across a wide range of system complexities, and supporting commercially viable implementations.

7. Core set of standards in place…
Nomenclature / Terminology
Information model
Application Profile – Base Std.
Transport Profile: Cabled
Transport Profile: IR wireless
Together these support connector-to-content interfaces!

9. Pending IEEE projects (PARs) …
– Recommended Practice – Profile template
– Nomenclature - Virtual attributes
– Application profile - Clinical context management (CCoM)
– Inter-LAN (vLAN, IP, medical session, QoS, security, UDP, TCP,
multicast discovery, addressing characters)
– RF wireless – Framework & Overview
– RF wireless – Local area network (wLAN)
– RF wireless – Wide area (mobile phone) network (wWAN)

10. Current activities include…
HL7 (v2.x) Observation Reporting Interface Gateway
RF Wireless transports
Profile templates
Application profiles (incl. external control)
Annotated ECG & IDC (pacemaker) terminologies
Dialysis device specializations (incl. treatment summary reports)
Conformance testing tools
Operating Room of the Future Plug-n-Play Initiative

11. IHE PCD will… Define open standards-based implementation profiles
Drive further standardization efforts
Enable realization of PCD value propositions!
