Ransomware hackers hit MercyOne in early October, part of a larger breach that caused hospitalwide outages at multiple health systems, according to The Des Moines Register.
CommonSpirit Health, a nonprofit health system based in Chicago, oversees 140 hospitals in 21 states; it was not clear how many of them hospitals were affected, and it declined to share the number.
For Rachel Cupples of Western Washington, the CommonSpirit Health ransomware attack meant delaying important surgery for weeks.
Like some other CommonSpirit Health hospitals that were affected, hers announced it was having trouble scheduling new patients.
Parsi and Cupples said they blamed the hackers, not the hospitals, for their pain caused by delayed care.
