Some patient and appointment updates from athenahealth not making it to Zus

The root cause of the issue that prevented some Athena updates from reaching the Zus data store has been identified and addressed. A fix was deployed yesterday, and monitoring has been ongoing to confirm stability.

Additional alerting has been implemented to ensure faster detection in the future, and plans are underway to introduce a self-healing mechanism to prevent data loss should a similar issue recur.

We’ve made an update to our data processing which has resolved this issue. We are going to keep this incident open as we continue to investigate the root cause and understand implications on historical data.

We are investigating some number of patient and appointment updates not arriving to Zus from athenahealth.

This issue does not impact clinical data coming from athena and does not impact a users ability to view the ZAP in Athena. The biggest impact is likely to be on up-to-date patient history queries if we miss a newly created appointment.
