I honestly do not think you've been neither fired or suspended. I am not sure about corporate hospital work, but I also worked in a contractor-based corporate environment with magnetic security cards, and it would be extremely unusual for them to just cut you off with no notice.
Also, if you are suspended, fired or quit from any such place, security WILL ask you for you card, most likely BEFORE deactivating it. I wouldn't worry too much if I were you, it's most likely an issue with the database.
