A cyberattack has disrupted services at the University of New Mexico Health System, forcing medical staff to change how they manage patient care and hospital operations.

The incident affected the health system’s computer systems, creating difficulties for staff who rely on digital tools to access information and coordinate services. Reports said the disruption led to ambulance diversions and the cancellation of some clinic appointments.

Cyberattacks on healthcare organisations can create serious problems because hospitals depend on computer networks for scheduling, medical records, laboratory results and communication between departments. When these systems become unavailable, staff may need to use alternative procedures to continue essential care.

Ambulance diversions can also place additional pressure on nearby hospitals. Emergency teams must decide where to take patients while considering travel time, available beds and the level of treatment each patient needs.

Healthcare workers often have to switch to manual processes during major technology outages. This can slow down routine tasks and make it harder to retrieve patient information quickly. Hospitals may also postpone non-urgent appointments while they focus on urgent cases and restore affected systems.

Cybersecurity experts have warned that healthcare organisations are attractive targets because they handle sensitive personal information and operate services that people urgently need. A successful attack can affect not only data security but also the delivery of medical care.

Hospitals can reduce some risks by keeping secure backups, updating software, limiting access to sensitive systems and training employees to recognise suspicious messages. They also need emergency plans that allow essential services to continue when digital systems fail.

Patients who have appointments at an affected facility should check official hospital communications before travelling and follow instructions from medical staff. Anyone facing a medical emergency should seek immediate help through local emergency services.

The incident highlights how closely modern healthcare depends on reliable technology. Restoring systems securely and maintaining patient care remain critical priorities after any major cyberattack.
