flag outside room door so staff can be found

[afteralltheseyears]

We are a small hospital with limited funds to purchase staff tracking technology (device that turns on a light above the room door so you can see when a staff member is in the room). Anyone have any ways of "flagging" a room so it is easy to see from down the hall when a staff member is in the room? I looked at the mounted metal flag sets that you can flip a colored flag up when a certain staff member (RN, LPN or CNA) is in the room-good idea but for our 24 rooms it would still be several hundred dollars. It would be money well spent as we waste alot of time hunting for staff going room to room but does anyone know of anything else even cheaper than that?

Everyone has great suggestions, but couldn't you just overhead page with your call light system and ask for "nurse Susie, please put on your call light?" You know immediately where she is and can talk to her if needed.
