Overview
- A computer outage began after a routine emergency power test and knocked several hospital IT systems offline, forcing the Maasstad Ziekenhuis to cancel most outpatient appointments and surgeries.
- The failure closed the emergency department and led nearby hospitals to take diverted patients while dialysis and oncology services continued on site.
- Partial services resumed the next morning when poliklinics reopened but the emergency department remained closed and operations were still being canceled.
- By Thursday afternoon the hospital announced the IT systems were restored and all departments, including the emergency department, were back in operation and patients with canceled appointments are being contacted.
- Hospital leaders say there is no sign of a cyberattack, patient data were not compromised, and they will carry out a careful review to find the exact cause and consider alternate IT routes to prevent a repeat.
