Hospitals rarely implement a policy like this without reaching out to local law enforcement and trying to come to some agreement on how it will be done. Its a very sensitive issue, and a hospital wants their policy to be approval by the cops to reduce their own liability, etc.
Absolutely 100% false. Hospitals adhere to strict confidentiality in spite of what law enforcement may want them to do. The insurance provider for the hospital puts on all kinds of training for nurses, doctors, PCAs, staff, etc. that instruct the type of conduct this brave nurse demonstrated for the sole purpose of AVOIDING liability. Absent a statutory triggering mechanism (i.e., search warrant, patient is under arrest) law enforcement gets ZIPPO - that's the standard across the board.
