ELI5: How do films/tv shows film get permission to film in hospitals?

I understand how for example if a TV set wants to film on a particular road or street they an get council/ government permission to close that area off to the public, who are able to find an alternate route. But a hospital needs all the space it needs and often must run at full capacity, so how can tv shows or film crews film in a hospital?

Most shows/movies use stages that are designed to look like a hospital. They are much easier to use and do not have all the hassles of trying to work around a real hospital.

Examples:

* Scrubs - filmed in a closed down hospital    
* General Hospital - filmed entirely in a Hollywood movie studio
* Grey's Anatomy - filmed in a Seattle studio 
* The Dark Knight - those famous scenes were filmed in an abandoned candy factory

I am not saying that no one films in a real hospital, but it is far far more common for TV shows or movies to use studios or other buildings and dress them up like a hospital.
