![Page 3: AIRA Update](https://reader030.fdocuments.in/reader030/viewer/2022021503/588a60aa1a28ab7a768b6869/html5/thumbnails/3.jpg)
Key Principles of
Interoperability
![Page 4: AIRA Update](https://reader030.fdocuments.in/reader030/viewer/2022021503/588a60aa1a28ab7a768b6869/html5/thumbnails/4.jpg)
Key Concepts
• Interoperability
Definition from HIMSS:
Interoperability describes the extent to which systems and devices
can exchange data, and interpret that shared data. For two
systems to be interoperable, they must be able to exchange data
and subsequently present that data such that it can be understood
by a user.
• Conformance
Definition of Conformance Testing from NIST:
Conformance testing is testing to see if an implementation meets
the requirements of a standard or specification.
![Page 5: AIRA Update](https://reader030.fdocuments.in/reader030/viewer/2022021503/588a60aa1a28ab7a768b6869/html5/thumbnails/5.jpg)
Key Principles
1. Standards should not be locally interpreted
![Page 6: AIRA Update](https://reader030.fdocuments.in/reader030/viewer/2022021503/588a60aa1a28ab7a768b6869/html5/thumbnails/6.jpg)
Key Principles
• Examples of local interpretations that change the
standard meaning:
– Using Administered-at Location (RXA-11.4) to indicate the facility
where the vaccination was recorded for historical immunizations
– Using Lot Number (RXA-15) to:
• Indicate flag vaccine funding source
• Store additional information, comments or details
– Not allowing Financial Eligibility Code “V01: Not VFC eligible” to
be reported for adults
![Page 7: AIRA Update](https://reader030.fdocuments.in/reader030/viewer/2022021503/588a60aa1a28ab7a768b6869/html5/thumbnails/7.jpg)
Key Principles
2. Conformance to standards should be testable
IG 2.3.1 HL7 2.5 IG Release 1.5
Does your system meet these standards?
![Page 8: AIRA Update](https://reader030.fdocuments.in/reader030/viewer/2022021503/588a60aa1a28ab7a768b6869/html5/thumbnails/8.jpg)
Key Principles
• Written standards and conformance testing
processes must be developed in tandem
– No normative standard should be approved without a
corresponding process to determine whether an
interface meets the standard
• AIRA is working with NIST to make this a reality– Implementation Guide Authoring Management Tool (IGAMT)
– NIST testing framework
– EHR Certification Testing
– IIS Assessment

Key Principles
3. Interoperability should be a science not an art

Future
Key Principles
• Interoperability as a science is still maturing
• Various initiatives are decreasing variability:
Present
• HL7 2.3.1
• IG 2.3.1
• HL7 2.9
• IG balloted by HL7
• NIST EHR Certification
• IIS Assessment
• Implementation Guide Authoring
• Functional Standards
• HL7 2.5.1
• IG r1.5
• NIST EHR 2015
Certification
Past
![Page 11: AIRA Update](https://reader030.fdocuments.in/reader030/viewer/2022021503/588a60aa1a28ab7a768b6869/html5/thumbnails/11.jpg)
Key Principles
4. Focus on interoperability not conformance
![Page 12: AIRA Update](https://reader030.fdocuments.in/reader030/viewer/2022021503/588a60aa1a28ab7a768b6869/html5/thumbnails/12.jpg)
Key Principles
• These organizations are working to establish standards:
– HL7: Create standards
– CDC: Foster data exchange
– NIST: Verify systems meets the standards
• Only IIS can:
– Collect complete and accurate immunization histories
– Manage inventory and track funded vaccines
– Ensure that data quality problems are prevented or detected
early and fixed
![Page 13: AIRA Update](https://reader030.fdocuments.in/reader030/viewer/2022021503/588a60aa1a28ab7a768b6869/html5/thumbnails/13.jpg)
Insuring Interoperability
• NIST certifies EHR system conformance:
– Confirms software is able to perform in a standards way
– How EHR and IIS actually operate in production is out-of-scope
• IIS must focus on interoperability
• Conformance is a tool IIS can use to help
• But a conformant interfaces can still fail to work
• And working interfaces can be non-conformant

Interoperability
Exercise

Usage: RE
• Examples:
– Patient Address (PID-11)
– Completion Status (RXA-20)
![Page 17: AIRA Update](https://reader030.fdocuments.in/reader030/viewer/2022021503/588a60aa1a28ab7a768b6869/html5/thumbnails/17.jpg)

![Page 19: AIRA Update](https://reader030.fdocuments.in/reader030/viewer/2022021503/588a60aa1a28ab7a768b6869/html5/thumbnails/19.jpg)
Usage: C(a/b)
• Example:
– Birth Order (PID-25) is C(RE/O)
• RE if Multiple Birth Indicator (PID-24) is Yes.
![Page 20: AIRA Update](https://reader030.fdocuments.in/reader030/viewer/2022021503/588a60aa1a28ab7a768b6869/html5/thumbnails/20.jpg)
Exercise
• Review message on Side A
– Identify as many conformance issues as you can:
• Focus on MSH, PID, and RXA segments
• OBX segments were removed for brevity, ignore this issue
• Review message on Side B
– This message meets current NIST standards for MU 2014
• Do not review it for technical issues
– Examine the message for data quality issues
• Contrast Side A and Side B
– Can conformance checking ensure high quality data?
– Can non-conformant messages transmit high quality data?

Pop Quiz
1. Can the IIS accept into production a message that does
not conform to CDC or HL7 standards?
2. If a required (R) field is empty, may an IIS still process
and store the data in the rest of the message?
3. If a not supported (X) field is valued,
must the IIS reject the message
entirely?
4. Can an IIS pick and choose
what data gets accepted
and what does not?

Proper Use of Required
• Use required to ensure proper structure
• Do not move fields to required to improve data quality
• Changing an RE to R can have un-intended
consequences
• Examples of un-intended consequences when health
industry marked certain fields as required:
– Patient Name (PID-5): Not all patients have names
– Administered Amount (RXA-6): May not be known
• It is better to improve data quality by creating auxiliary
processes for assessing data quality

Local Guides
• Keep local implementation guide short
– Less than 25 pages is ideal
– Consider making a 1-2 page “delta guide” to show difference
between CDC IG and Local IIS IG
• Document how errors and warnings are messaged and
handled by the IIS
• Follow HL7 constraining rules
– R and X usage can not be changed
– RE can go to R
– O can be changed to R, RE or X
• Prepare for transition to the new NIST Immunization
Authoring Guide Management Tool

Big Picture
• Discovery Phase
– IIS Interoperability Status Check Project
• Connect to IIS test systems
• Submit a thousand VXU and QBP messages every month
– Aggregate Analysis Reporting Tool (AART)
• Collects information from all tests performed
• Create AART Report for IIS to see the results of testing
• Assessment Phase
– Measurement for Assessment and Certification Advisory Work
Group (MACAW) was convened this spring
– MACAW will lead community to set assessment measures
– Certification will build on assessment work, but certification is still
on the far horizon and details are yet to be determined
