That's amazingly accurate, this is not for navigation purposes within the hospital but for advertising on the hospital grounds (typically a substantial multiple of 100 yards). It's not like you want to direct someone to a certain wing, though it is probably even accurate enough for that .
Besides, for many phones it is much closer than that, because location services are enabled for instance for Google (because someone used Google maps) or because some app has linked an SDK that lifts the location data from the phone and moves it to some server.
