Tri-City Medical Center in CA Operations Affected for Days

November 14, 2023


Tri-City Medical Center is diverting ambulance traffic to other hospitals Thursday as it copes with a cybersecurity attack that has forced it to declare “an internal disaster” as workers scramble to contain the damage and protect patient records. The Oceanside facility’s management confirmed the situation in a brief statement, indicating that the hospital’s emergency department remains “prepared to manage emergency cases” that may arrive in private vehicles and is “working with our other health system partners to ensure the provision of health care for our community.”

On Monday, 13 November, ambulance deliveries remain diverted from its emergency department and elective procedures remain canceled as the medical provider deals with the fallout of an attack on its digital assets and continues to operate in a state of “internal disaster.”
