This document discusses standards for interoperability and communication for multi-parameter vital signs monitors. It describes organizations like HL7 and IHE that establish standards, as well as integration profiles defined by IHE like DEC and POI. HL7 provides basic integration standards, while IHE defines technical frameworks and profiles to organize these standards and decrease ambiguity. Examples of commercial vital signs monitors that implement IHE PCD profiles are also given.

FHIR is the latest standard to be developed under the HL7 organization. Pronounced 'Fire' , FHIR stands for Fast Healthcare Interoperability Resources. I think it's the most interesting standard to have come out of HL7 since the original HL7 protocol.
iUZ has organised last 3rd July a talk about Cross-Border Interoperability and we've broadcasted live on Youtube.
This is the presentation document.

1. Multi-parameter Vital Signs Monitors
Interoperability and Communication
Standards

August /2015
2. Organizations
• Health Level Seven International (HL7)
• ANSI-affiliated organization
• HL7 domain is clinical and administrative data
• Founded in 1987
• Provides interoperability standards in order to improve healthcare systems, optimize
dataflows, reduce ambiguities and enhance the data exchange
• Integrating the Healthcare Enterprise (IHE)
• Healhcare professionals effort
• Promotes the coordinate use of established standards such as DICOM and HL7
• Provides interoperability specifications, tools and services
• Founded in 1998
• All documents, specifications and e-mails are freely available on the IHE website
• There are annual fees for member organizations. Members can submit equipment to tests
and standards check.
01/05/2017 2
3. HL7 vs IHE
• HL7 provides vocabulary and
basic grammar to the integration
language
• IHE Technical Frameworks
organize these elements,
providing the most relevant
standards, decreasing confusion
and ambiguity
01/05/2017 3
4. IHE :: Specifications
• IHE Domains
• IHE is organized by clinical and operational domains
• Cardiology, odontology, ophthalmology, laboratory, patient care coordination, patient
care device, TI infrastructure, radiology, …
• Each domain has one or more Integration Profiles
• IHE Integration Profiles
• Provide a standards-based framework for sharing information within care
sites and across networks
• IHE Profiles are compiled into IHE Technical Frameworks-detailed technical
documents that serve as implementation guides and Technical Frameworks
freely available online
01/05/2017 4
5. IHE :: IT Infrastructure Domain (ITI)
• Most equipment must cover some IT Infrastructure profiles, for
instance:
• Consistent Time (CT)
• Defines mechanisms to synchronize the time base between multiple actors and
computers (NTP)
• Patient Administration Management (PAM)
• Establishes the continuity and integrity of patient data, and additional information such
as related persons (primary caregiver, guarantor, next of kin, etc.)
• …
01/05/2017 5
6. IHE :: Domain and Profiles for Vital Signs
Monitors
• Domain: Patient Care Device (PCD)
• Released in 2005
• Address the integration of medical devices into the healthcare enterprise, from
the point-of-care to the EHR
• PCD Integration Profiles for Vital Signs Monitors
• [DEC] Device Enterprise Communication
• [POI] Pulse Oximetry Integration
• [ACM] Alert Communication Management
• [WCM] Waveform Communication Management
01/05/2017 6
8. IHE :: Integration Profiles PCD
• [DEC] Device Enterprise Communication
• Supports publication of information acquired from point-of-care medical devices to applications such as
clinical information systems and electronic health record systems, using a consistent messaging format
and device semantic content
• [POI] Pulse Oximetry Integration
• Specifies how implementers could use the existing DEC and PCD-01 transaction to exchange pulse
oximetry observation sets with clinical information systems
• [ACM] Alert Communication Management
• Enables the remote communication of point-of-care medical device alert conditions ensuring the right
alert with the right priority to the right individuals with the right content
• [WCM] Waveform Communication Management (under development)
• Extend the [DEC] profile to provide a method for passing near real-time waveform data using HL7 v2
observation messages
01/05/2017 8
9. IHE :: Integration Profiles PCD
• Pulse oximetry is the only device that has a specific profile [POI]
• Other devices must comply DEC requirements (PCD, vol. 3, section 7.3)
• Glucometer semantic table was not found, only the ISO document
01/05/2017 9
11. IHE :: DEC Profile :: Trigger events
• Can be sent with or without a preceding order
• While a DOR Actor may be implemented directly on a medical device,
it is more often implemented on a gateway or intermediary device as
an application which implements the DOR, receiving data from one or
more patient care devices
• Trigger interval: several times per minute, typical interval of 1 minute
• The minimum and maximum intervals are configured at implementation

July, 2015.
There are other 27 devices, mostly gateways that translate proprietary structures and
protocols to IHE/HL7 standards
01/05/2017 12
13. HL7 :: Versions
• v2 (1990)
• Most popular version, used by IHE profiles
• Minor versions: 2.1, 2.2, 2.3, 2.3.1, 2.4, 2.5, 2.5.1, 2.6
• Some minor versions are mutually incompatible (for instance: 2.5.1 and 2.3)
• v3 (2006)
• XML as message format
• FHIR - Fast Healthcare Interoperable Resources (2012)
• Specification for exchanging healthcare data in a modern and developer
friendly way
HTTP based RESTful protocol
• Most recent (under development)
01/05/2017 13
14. HL7 :: Message format
• HL7 v2 – ER7
• Most popular format
• Used since the first HL7 version
• Multi-line and pipe as field separator
• HL7 v2 – XML
• Not widely used
• “Direct” conversion from ER7 to well-
structured format
• HL7 v3 – XML
• Many details and validations
• Largest message size
• FHIR – JSON or XML
Incompatible
01/05/2017 14
15. Example of HL7 v2 EL7 message - Glucose
MSH: Message Header
PID: Patient Identification
OBR: Observation Request
OBX: Observation Result
01/05/2017 15
16. Network protocols
• MLLP (Minimum Lower Layer Protocol) [HL7/IHE]
• Traditional way with TCP sockets, used since the HL7 launch
• Used in HL7 v2 as well as HL7 v3
• SOAP-WebServices [IHE]
• Released circa 2011, not widely used
• ER7 format encapsulated in a XML SOAP. IHE provides WSDL, XML schema, etc.
• IHE DEC profile suggests MLLP or WebServices (PCD Vol 2 Appendix I e J)
• ebXML (Electronic Business Extensible Markup Language) [HL7]
• SOAP based, but HL7 v2/v3 are converted to “ebXML” format
• HL7 over HTTP [HAPI]
• Launched in ~2012, not so popular
• HL7 over HTTP is an initiative to provide a standardized transport mechanism to send HL7 v2 messages
over a network using the HTTP protocol
• HTTP resources can be used (criptography, authentication, etc), therefore some overhead must be
taken into account
• HL7 FHIR HTTP (REST) [HL7]
01/05/2017 16
17. HAPI (HL7 application programming interface)
• Open-source, object-oriented HL7 2.x parser for Java
• Not affiliated with the HL7 organization
• Java API
• Full featured Java API you can use to add HL7 capabilities to your applications
• TestPanel
• Full featured HL7 message editor, transmitter and receiver
• HAPI-FHIR
• Open-source implementation of the FHIR specification in Java
• HAPI ignores HL7 v3
