Leveraging IHE profiles
and the upcoming
IHE conformity assessment in
ehealth projects

EU-Affairs and IHE Services Committees
1
strategic overview and practical principles
Bring the most recent developments in IHE to achieve
interoperability within various eHealth projects such as :
 Hospital and Hospital groups
 Regional health information exchange platforms
 National ehealth programs
Todays focus is to address the critical question of
establishing the necessary overall interoperability
governance process to solve technical and semantic
interoperability
 Note: The legal and organizational policies that ensure information exchange
participants operate with trust and clinical relevance are critical but not within the
scope of this presentation

For an effective Interoperability Governance
How should organize the processes in an eHealth program
to deliver effective interoperability ?
 Address and focus on my ehealth program objectives
 Allows the best use (and reuse) of IHE profiles
 Sets the role and structure for an Interoperability
Specification that bridges the gap between my use cases
and IHE profiles
 Assesses conformity of implementations to IHE profiles and
my Interoperability Specifications
 Establish a project specific testing platform to drive
production level interoperability.
 Can the IHE International Conformity Assessment program
to be launched in April at the Luxemburg Connectathon help

From the project specific Interoperability

Interoperability
Testing
The IHE Global Standards Adoption Process
First Step:
Select and Document a Business Use case.
Document the interoperability needed to support
Second Step:
Meet the interoperability requirements of the
business use case by specification in an
interoperability specification of:
 a combination of a suitable set of profiles
 remaining gaps by project specific custom elements
 How is this done ?

Use Case: Sharing Patient Summaries
Business Use Case (simplified):
A Patient Summary Service allows creation and access to a
standardized set of basic medical data that includes the most
important clinical facts required to ensure safe and secure healthcare.
This data is intended to aid health professionals in providing better
coordinated care as well as unscheduled care.
A medical summary consisting of general information and clinical
patient data (e.g. allergies, current medical problems, implants, or
major surgical procedures, current prescribed medications.
This service should ensure:
•
That health professionals access information either from specific
encounter or review and aggregate information across time
•
Attribution , consistency and accountability by the professionals
•
Patient’s control over access to shared information

What is meant by Conformity Assessment?
Test Report provided by a trusted neutral
organization that guarantees that an IHE profile
implementation in a commercial products is
positively tested against an IHE test plan/test tools
 Specific version of a specific product (re-testing may be
needed for every major version).
Does not imply that retesting is
needed for each product/version (e.g. using same software).
 The process and rigor of “Conformity Assessment” to be
defined in terms of a “conformity assessment scheme”
(process, test plan and test tools) to ensure world-wide
equivalence.
 Expects a vendor to pass appropriate Connectathon tests as a
prerequisite for seeking profile/actor accredited testing

Elements of an IHE Conformity Assessment Scheme
A single international scheme with delegation
of accreditation operation testing at the
national/regional level.
Allows IHE National/Regional Deployment
Committee to deliver a internationally
recognized testing report based on
transparency
Testing of National extensions/combination of
IHE Profiles is to be addressed as a subsequent
testing step (“projectathon” or ehealth projectspecific interoperability specification).

IHE Conformity Assessment for who ?
1.
The larger eHealth Projects (national, regional,
hospital network) that want to engage a broad
number of vendors to supply products with IHE
profile conformance. Use IHE Conformity
Assessment as an entry criteria into procurement
and project level lab testing (Projectathon).
2.
The care delivery organization with simple
interoperability projects (e.g. connecting devices to
a Clinical System). Only a few profiles to be
combined.
3.
Vendors that want to avoid the overhead of retesting
in each project at the profile level.
