Tri-City Healthcare in North County San Diego was the victim of a ransomware attack that halted the facility’s ability to accept patients Thursday, a source told NBC 7.
Tri-City, which has a medical center located in Oceanside, California, placed itself on an Internal Disaster Diversion with San Diego County’s Office of Emergency Services, county officials said.
“This means the hospital cannot accept any patients through the 911 system because of a critical disruption of the ability to provide medical services,” the county said.
An Internal Disaster Diversion can be initiated due to structural failures, infrastructure, disruptions or health and safety threats, according to a county health and safety code update in July 2021.
NBC 7 is in the process of reaching out to Tri-City Healthcare to confirm it asked the county for an internal disaster diversion and other details
The North County medical center recently announced a partnership with UC San Diego Health, which was set to take over the healthcare facility’s operations next March.
UC San Diego was itself a victim of a data breach in 2021. In that incident, employee email accounts were targeted that may have contained personal information about patients, students and employees. UCSD Health said patient care was otherwise unaffected.
About 147,000 patients were likely affected by a ransomware attack upon Scripps Health in 2021. The healthcare system agreed to a class-action settlement a year later. And, in 2020, San Ysidro Health was hit by a similar attack that compromised patient information.
