After at least a 45 minute to a hour wait someone should assure patients that they are not forgotten and will be seen. After being seen by the nurse and in the room again for about an hour with the door closed, someone should let you know you're not just left in the room forgotten. I should not have had to walk out in the hall to see if the doctor knew I was waiting. I know there are other patients to be seen but some kind of acknowledgment would be comforting.
