This is why a policy of good, regular data backups (and regular restore/DR testing) is critical, especially in healthcare IT. I have had to deal with this on a smaller scale, and generally we have data unlocked and available within a few hours at most. Mind you, there may be data missing from the last 24 hours, but with the nature of ADT (Admission, Discharge, Transfer) data interfaces (and archiving), much of that data can be played back into the affected systems.
That being said, real doctors can do their job without computers. Definitely less efficiently, but they can still get the job done…
