Depending on the door/situation, you could also try the following: position yourself in a way that the monster in front of the door won't be able to see you through the grates (if there are any), becouse if it can see you, than it knows you're inside and will stay in front of the door; the same goes for trying to open the door with the monster in front of it - don't. Try crouching in a corner with no direct view from the door, face the wall and go make yourself a sandwich (or wait)
