Recent news about hacking at a hospital in the US.

“A cyberattack launched against the Hollywood Presbyterian Medical Center has forced staff to declare an “internal emergency” and left employees unable to access patient files.

[…]

As medical records including patient details, X-rays, CT scans and lab work could not be accessed, this has made the situation very dangerous for patients.

As a result, a number of patients have not been able to receive treatment and some have been transported to other hospitals.

Medical staff have been relying on fax machines and telephones as the week-long outage continues to wreak havoc, which had led to a decrease in efficiency and an inability, in some cases, to safely help patients”.
