Data Exchange with CAIR2

Will the current data exchange (DX) process be different for CAIR2?

  • Yes, there will be a few minor changes to the HL7 message specifications, including the addition of an MSH-22 'Responsible Organization' field, plus changes to the SOAP transport configuration. Refer to the updated CAIR2 HL7 2.5.1 Data Exchange Specifications and CAIR2 Test Plan documents for CAIR2-specific changes. Please note that flat-files will not longer be accepted after the launch of CAIR2.  
  • Also, because the new software will be able to return HL7 ACK (indicating message status) messages to the submitter for each message received, Sites should discuss with their EHR vendors whether such messages can be received and displayed by their EHR systyems for data quality monitoring purposes.  If your Site is submitting through a Sending Facility (SF), you should also consult with your SF contact to determine whether the ACK messages returned by CAIR2 to the SF can be forwarded back to your EHR system. 
  • If ACK messages are not available in your EHR, new functionality in CAIR2 will allow 'Power' users at your Site to monitor data exchange activities.  'Power' users will be oriented to this new functionality during the required CAIR2 trainings but more extensive training and training materials on the use of this functionality will be offered by our DX staff later.  An additional 'DX Quality Assurance' user role is in the process of being created to allow your technical and/or QA staff to also monitor your Site's data exchange activity.   If your Site doesn't currently have a 'Power' user and/or would like to enroll a 'DX Quality Assurance' user, after your region transitions to CAIR2, go to CAIR Account Update website to user accounts for your staff.

When will these changes need to be in place?

  • On October 3, 2016, all data exchange message submission will be transferred from the IZ Portal to the new CAIR2 system.  Therefore, the all required CAIR2 message and SOAP changes must be implemented on that date or messages will be rejected.  To maintain data continuity for users still using the CAIR1 software after October 3, 2016 (Bay Area, Central Valley, and LA-Orange), data exchange doses received by CAIR2 will be synchronized back to each CAIR1 registry until each transitions to CAIR2. See the CAIR2 Timeline for when each regions  users will transition to use of the new CAIR2 software.
  • 'Power' and 'Regular' users at data exchange sites will also need to attend training. See the CAIR2 Timeline for when regional users will be eligible for and need to attend training.

What other benefits will CAIR2 have for DX sites/ users?

  • Submissions from your EHR to CAIR2 will be smoother, and messages will be less prone to being rejected. 
  • Patient and dose information sent from your EHR will be available in near real-time (within seconds).
  • DX messages sent to CAIR2 can now decrement from CAIR2 inventory but you will need to contact the CAIR DX Staff at to get this functionality turned on for your practice.

We have users who log in to CAIR. Will these users need to be trained to use CAIR2?

  • Yes.  All 'Power" and 'Regular' Users who access CAIR through the web interface will need to be trained before being given access to CAIR2. See the CAIR2 Timeline for when your regional registry will be transitioning to CAIR2 and when your site's Users will be eligible to sign up for and receive the required training.

My site is interested in bi-directional data exchange (BiDX).  When will that roll-out and how should we prepare?

  • CAIR2 will allow patient information to be returned to EHR systems through a process called bi-directional data exchange (BiDX). This involves submission by the EHR to CAIR2 of a patient query message and the return of a patient history and recommendations by CAIR to the EHR system. A formal testing and onboarding process for BiDX, independent of the current one-way data submission process is required. Onboarding of Sites to BiDX has begun. Sites interested in BiDX including data aggregators/HIEs) are required to complete the CAIR2 Bi-directional Data Exchange Interest/Readiness Survey. Interested sites should also review the national CDC HL7 2.5.1 Release 1.5 specifications and Release 1.5 Addendum for proper message formatting.  If you are a direct submitter (EHR to CAIR, no data aggregator/HIE), please consult with your EHR vendor support as to the bidirectional readiness of your EHR. 
  • To get the most value from the BiDX process, each site should consider submitting all active patient historical doses to CAIR so that patient vaccination recommendations returned to your EHR will be correct.  Consult with one of our CAIR Data Exchange Specialist about submitting prior immunizations records (historical data) for your active patients.

Will there be additional costs for bidirectional data exchange?

  • While access to CAIR is free, you will need to consult with your EHR vendor to determine if you current system is capable of bi-directional messaging and if there would be additional costs for implementation.
