How to get doctors, visiting nurses and facilities to work together to not have so many appointments? I fear I am going to lose my job!

I am having to take so much time off of work because the Doctor makes me bring my Mother in to the office for something as simple as a blood test result...she also has a visiting nurse come in but some facilities choose not to "work" with them which requires separate appointments...I am at the least having to take her to an appointment 2 to 3 times a week....can you point me in the direction where I can get assistance in getting these place to work together?...
