Heads-Up: Intermountain's switch to Epic EHR and what to expect on cutover day.

The issue is resolved. Federated Query is back online.

Please note: This fix has introduced an unintended behavior. Once the query has finished running and the “Federated Query update completed” message appears, users must refresh the browser tab to see the document.

Our vendor has been notified and is working on a fix. In the meantime, please remember to refresh your session to view the latest data from IHC. We apologize for the inconvenience and will let you know when the refresh step is no longer required.

Epic ADTs are now flowing successfully, and the ADT Service is fully operational.
The federated query remains down at this time. We're actively working with our vendor and Intermountain to get this resolved and will keep you posted as soon as a fix is in place.

As a reminder, Intermountain is transitioning to Epic on September 6th. Their rationale for the A03/A01 approach:
- Reduces interface complexity and supports standardized workflows across ancillary systems.
- Ensures compatibility with medication management and other ancillary systems that require a clean discharge/re-admission process for continuity and integrity.
- While a silent cutover could reduce visible disruption, it adds significant planning and technical complexity. The discharge/readmit model simplifies configuration and lowers go-live risk.

UHIN's MPI will link new and old MRNs from Intermountain before we begin routing the new Epic ADT messages to you. Approximately 2,500 patients are expected to have a Cerner A03 and an Epic A01 message. Please monitor your feeds and let us know if you encounter any issues.

Intermountain is transitioning from their Cerner-based EHR (iCentra) to Epic, with a planned cutover date of September 6, 2025. During the cutover, all inpatients will be discharged from iCentra and admitted into Epic.

For consumers receiving ADTs:
(i) You will first receive A03 discharge messages from iCentra (with iCentra’s MRN)
(ii) Followed by A01 admit messages from Epic (with the new Epic MRN)

We’re checking with them whether A08s might be an alternative or whether specific values will be included in relevant HL7 segments to help us distinguish between technically triggered discharges and actual patient discharges. We'll keep you updated as we learn more.

Please plan accordingly and let us know if you have other questions.
