Yes we do and I wish all service providers had similar communication access.
My mom's doctor, test results and medical records are available to me 24/7. Often I see test results before the doctor does.
I have periodic email conversations with her about mom's medications, test results and minor illnesses. Before our regular appointments with her I send her a list of items I want to cover with explanations. It saves time and let's her use the time to focus on mom rather than listen to me giving the background info she could more easily read and it makes mom more comfortable not to have us talking about her worsening symptoms in front of her.
