Living Dead Lock Up 2: March of the Dead (2007)

The first film in this series (number 4 is being shot) had the clever idea of being chased by zombies when confined to a prison; it unfortunately made little of that. This second film takes place in a hospital, rather than the prison and as far as "March of the Dead" goes, there's never more than 3 or 4 zombies on screen. The hospital seems to have a total of 4 people, including staff and patients. It's extremely low budget (under $1000), but has nothing to make up for that. What more do I need to say?
