There is actually a counterexample to this that is happening right now. The Scripps hospital system in San Diego was hit with ransomware about two weeks ago and has been more or less down since then. Patients are not able to make new appointments, medical records are unavailable. My understanding is that doctors are still seeing patients if they have existing appointments, but surgeries are getting performed at other hospitals in other health systems.
