 Supporting Data
 Future Directions
 Conclusion
CIR HISTORY
 Started in 1997
 Contains 70 million immunizations for 5.2
million patients
 Approximately 1800 active provider sites
 Reporting is mandated for patients 0-18,
consent is required for reporting immunizations
given to adults
 Paper reporting  Online registry  Flat file
 real-time HL7
CIR’S HL7 DATA EXCHANGE
 Real-time, bi-directional exchange through a
SOAP web service
 No batch file option for providers
 First facility began submitting data through the
web service in February 2011
 Currently 465 provider sites + 400 pharmacies
sending HL7 data through the web service; (189
provider sites are bi-directional)
DEFINITIONS
 Real-time
 Synchronous Transport- User submits an HL7 message,
and as part of that transaction/connection to the IIS, the
application waits for an acknowledgment response
 Synchronous Processing- Upon receipt of an HL7
message, IIS processes the message and
acknowledges the results of processing. Data is
immediately accessible to users of the IIS.
 Bi-directional
 EHR sends an HL7 query message (VXQ or QBP) and
receives a response containing patient’s immunization
history, evaluation and decision support
 EHR imports IIS data and stores it as structured data
INTEROPERABILITY STANDARDS
 HL7 2.5.1
 Supported by 44 immunization registries as of Sep
2013
 Well-defined standard for immunization reporting
(VXU) and query/response (QBP/RSP)
 SOAP Web Services
 National standard recommended by CDC’s
Transport Layer Expert Panel
 Supported by 30 immunization registries as of Sep
2013

BENEFITS OF REAL-TIME
BI-DIRECTIONAL EXCHANGE
For Providers:
 Avoid double data entry (89 CIR facilities have moved
from online registry to HL7 web service)
 Accessibility of information (both immunization history
and clinical decision support) within provider workflow
 Accuracy of data within provider EHR
 Data immediately available in IIS for use with school
forms, other pre-completed forms
 Particularly beneficial for first-time EHR implementers

BENEFITS OF REAL-TIME
BI-DIRECTIONAL EXCHANGE
For an IIS:
 Timeliness
 Completeness of immunization information (lot number,
manufacturer, expiration date, etc)
 Providers have continuous interaction with the IIS

MEANINGFUL USE AND IIS
CIR built HL7 web service in 2009
Stage 1:
Began January 2011; Eligible providers and
hospitals must perform a test of EHRs
capability to send data to an IIS in HL7 format
Stage 2:
Began January 2014; Eligible providers and
hospitals must institute ongoing reporting to
an IIS in HL7 2.5.1 format

service

CHALLENGES OF BI-DIRECTIONAL
HL7 EXCHANGE
 How can we ensure that the IIS finds and
returns the correct patient?
 EHR should send all possible demographic information
 Exchange unique IDs (Medical record number, IIS ID)
 Will the EHR display IIS data correctly?
 Thorough testing with the EHR vendor
 Involve providers in testing
 How will the EHR de-duplicate immunizations?
 EHR record and IIS record must be fully synced
to ensure accurate clinical decision support
BEST PRACTICES FOR REAL-TIME
BI-DIRECTIONAL EXCHANGE
For IIS:
 Webinars (or site visits) with providers to understand
how their EHR works
 Set up the ability to restrict queries from specific
accounts
 Store unique IDs sent by the EHR
 Data quality monitoring; daily e-mails
For EHRs:
 Store patient’s registry ID and send in all transactions
 Automatic re-query to get decision support updated
 Full sync of registry record with EHR record —critical
for accurate decision support
FUTURE DIRECTIONSIIS COMMUNITY
 Advocate for MU Stage 3 to include bidirectional exchange
 Reduce Variability in HL7 implementations
between IIS
 Find ways to partner with EHR vendors that will
be mutually beneficial
 Create a set of recommendations to EHR
vendors for best practices
CONCLUSIONS
 Meaningful Use has facilitated increased adoption
of HL7 standards among practices reporting to CIR
 Real-time, bi-directional exchange is feasible and
scalable to a large number of facilities
 Presents a number of benefits to both providers
and IIS
 IIS nationally have well-defined standards for
message content and transport
 Preference of EHR vendors in MU stages 1 and 2
has been for a unidirectional HL7 interface;
inclusion of a bi-directional requirement in stage 3
would accelerate implementation of bi-directional
interfaces
