Outside of the examination rooms in my doctor’s office (nay every doctor’s office I’ve ever seen) is a set of colored plastic bars near the door. There are about six. The lowest one is the shortest and is probably five inches long. Each bar above it is, in succession, a different color and is about 1/2 inch longer than the one below it.
I assume that these bars indicate patient care in some way (for example: whether his/her vitals have been taken, whether he/she is contagious, whether he/she is undressed). Is there a standard for all of those bars across every doctor’s office in the U.S., or is each physician free to set his/her own system? How do you actually derive information from them? Does the color of the bar indicate something, or is it the bar’s position (topmost, lowest, etc.)?
