Integration vs. Interoperability Why Should I Care?
Integration What, Me Worry? Integration of patient connected medical devices with IT Systems is increasingly becoming a clinical requirement. Is there a problem? Most, if not all, EMRs can connect to devices We have a growing contingent of vendors (Capsule, Nuvon, Cerner, etc.) providing device integration middleware and services. Patient monitoring vendors have created integrated systems incorporating many 3rd party devices. Clinicians have developed many demonstrations and applications showing device integration.
However, There is a Problem Some issues with our current reality Each new device integration is a custom effort requiring months of effort using skilled engineers Clinicians desiring to use a new device must wait for their application vendor to develop a new driver (which may never happen) The complexity of device interfacing may be hindering research which could lead to improved patient care Purchasing decisions are driven by whether an interface to specific devices exists Safety issues can arise due to the sizable software effort and on-site customization required to integrate devices
However, There is a Problem More issues with our current reality Costs to Providers for system integration services are very high There is reduced assurance that all data is accurate and complete Not all required data to accomplish a Use Case may be available There can be finger pointing when trying to resolve problems Too much complexity in maintaining each link in the communication chain As device or system software is updated solutions break
Are Standards the Solution? Well, we have plenty of standards: HL7 IEEE 11073-10101, 10xxx, etc. IEEE 11073-20601, 40xxx, etc. ASTM F2761 (ICE) DICOM ISO TC215, CEN TC251, IEC, etc. Standards are just a starting point.
Is Interoperability the Solution? What is Interoperability? Unfortunately current definitions of Interoperability are not helpful Interoperability is the ability of health information systems to work together within and across organizational boundaries in order to advance the effective delivery of healthcare for individuals and communities. (HIMSS) So we already have Interoperability in the medical device space! I call this Dysfunctional Interoperabilty
So, What is the Solution? The solution is Device Interoperability based on Framework(s) of Open Standards, Profiles, Conformance Testing, Certification Testing, Regulatory Pathways, etc. Incentives that drive all parties to comply with these Framework(s) Call this Open Interoperability How does IHE PCD contribute to the concept of Open Interoperability?

Role of IHE PCD IHE PCD was formed in 2005 to address issues related to integration of Point-of- Care medical devices: With each other With enterprise systems IHE PCD wants to raise the bar from the current state of integration projects to out of the box, open, interoperable solutions. IHE PCD s co-sponsors are HIMSS and ACCE.
IHE PCD Charter The Patient Care Device Domain is concerned with use cases in which at least one actor is a patient-centric point-of-care medical device. The PCD coordinates with other IHE clinical specialty based domains such as medical imaging and lab to ensure consistency of medical device integration solutions across all IHE technical frameworks.

IHE PCD From Use Cases to Profiles
From Use Cases to Profiles The IHE process starts with an open call for Work-Item Proposals to all stakeholders. The proposals are reviewed and voted on by the Planning Committee. Proposals are evaluated on clinical benefit, technical feasibility and volunteer availability. So far most accepted proposals are related to enterprise connectivity (as contrasted with Point of Care). Vendor gateways (MDDS) to enterprise systems are easier to modify than regulated devices. Profiles are typically developed in 18 months or less. Some vendors are starting to implement PCD profiles directly in point-of-care medical devices.
Use Cases to Profiles - Developed Use Case: Time synchronization across multiple devices and systems Profile: [CT] Continuous Time, based on NTP Use Case: Reporting of device data (heart rate, infusion volume, airway pressure, etc.) to consuming systems Profile: [DEC] Device to Enterprise Communications, based on HL7 syntax and ISO/IEEE 11073 Device Model and Nomenclature. Also adopted by Continua for WAN reporting.
Rosetta Terminology Mapping [RTM]
Use Cases to Profiles - Developed Use Case: Reporting of implantable device data (Device state, ECGs, etc.) to EHRs Profile: [IDCO] Implantable Device Cardiac Observation based on HL7 syntax and ISO/IEEE 11073 Nomenclature. Use Case: Reporting of alarm/alert information to various systems such as alarm consolidator and paging solutions Profile: [ACM] Alarm Communications Management, based on HL7, ISO/IEEE 11073 and WCTP Standards.
Use Cases to Profiles - Developed Use Case: Communication of orders to the infusion device directly from the BPOC/BCMA (confirmed by the clinician). Profile: [PIV] Point of Care Infusion Verification, based on HL7 and ISO/IEEE 11073 Nomenclature Standards. Use Case: Communication of waveform information (snapshots or continuous) from devices. Profile: [WCM] Waveform Content Message, based on HL7 and ISO/IEEE 11073 Device Model and Nomenclature Standards.
Use Cases to Profiles In Process Use Case: Retrospective data retrieval from device data stores to backfill EMRs or supply Clinical Decision Support Systems. Profile: [ADQ] Asychronous Data Query Use Case: Communication of device data and control at the Point of Care (PoC). Profile: [DPI] Device Point of care Integration
Use Cases to Profiles In Process Use Case: Improved association between devices and the patient. Profile: [PCIM] Point of Care Identity Management Use Case: Communication of Events (pump stopped, bolus given, etc.) from devices to consuming systems. Profile: [IPEC] Infusion Pump Event Communication
Use Cases to Profiles In Use Case: Process Management of medical devices: Profile: Device location Device cyber security Device technical management (access to device logs, error logs, SW and HW revisions, etc.) [MEM] Medical Equipment Management
