Nashville, Tenn.-based Ardent Health Services is still working to restore its MyChart system after a Nov. 23 ransomware incident rendered it offline.
In a cybersecurity update on Ardent's website, the health system said "new systems are coming back online on a regular basis," and that its investigation into the incident is ongoing. Ardent said it's still determining if patient information was compromised as a result of the breach.
This comes shortly after Ardent said Dec. 6 that it has restored access to its Epic EHR system.
