I went to PAMF in Palo Alto, california yesterday for a "group diagnosis session" with the dermatologist. It seems dermatologist appointments are hard to get, so they came up with this method. You sit in a circle with other patients and doctor comes to each of you and quickly checks what happened to you and prescribes medicines. If she thinks it requires deeper consultation, she will scheduler private visits. I thought this is a good system, especially if you are young and kind of know that what you have is one off fever or some such thing. What am I missing? Why are more hospitals not following this? Why is no one applying to YC with this idea?
