I use Yahoo Messenger. Granted, it is not secure but I do not put in any last names or other important info. In each of my exam rooms, I have a different Yahoo Messenger identity..."GardenDoc, BeachDoc and CabinDoc". The staff, who each have their own Yahoo identity know who is in that room. I can messenger up front and say "Please find Susan's CT from FMH from Oct". The patient isn't even aware I have sent the message to staff. Within a few minutes, here comes the report under the door. Or, I can message back to billing..."Susan will be out in a minute and has a question about her encounter date 2/2/08". The billing staff can already have everything pulled up and waiting on her. I can also ask the staff to "rescue me please" if I get stuck in a room with a chatty patient. Within a minute or so there is a knock on the door telling me the ER is on the phone and needs to speak with me. Works great, especially because as soon as a message reaches someone, there is a highlighted bar on the toolbar letting them know a message is there and who is messaging them.
