You will invariably videotape someone other than your intended subject. That person has the right to not be recorded in the private, vulnerable setting that is a hospital. In addition, a lot of medical providers do not like a videotape of their acts in case something goes wrong and the videotape can be used against them, especially if it's bloody and a jury doesn't like seeing blood, even if it's not the doctor's fault. Medical cases get to be decided based on the providers' written records, which logically are carefully written after an incident occurs. So leave your recording devices at home and wait for the written account later.
