In this hospital, there are demented ones who used to be patients, mutated beyond reason. There are some that display some degree of sentience, enough not to attack, but there are the others that will kill you on sight. The hospital is dark, and your light source is usually the only way to see. There is no combat possible. The only way to evade enemies is to either hide, run, or shut doors in their face. Most mutated patients will try to bust down locked doors, but others open them.
