How can I get my mother's doctors to exchange information and work as a team?

A fellow caregiver asked...

Has a whole team of doctors who though are able to connect with one another on same computer system they don't. Every time my mother has to see someone new its like I have to start all over again with explaining how her body react to different things only for them to look me in my face and tell me that's not true but later find out that I was right all along. I feel burnted out and that the doctors, nurses, and home care professionals look down at me cause I didn't go to med school and its causing me to be angry and depressed all the time cause this is my mother not theirs.
