Could your issue be a technical one dependent on the provider?
I have doctors in different healthcare networks, and so I have had the opportunity in this last year to compare them. I find that the big networks (Allina, Park Nicollet, Mayo) have very good MyChart pages with a technical support phone number. So, one only has to "create an account" and things are pretty clear. And one has the ability to forward documents to another network of providers.
BUT SMALL PRIVATE GROUPS OF DOCTORS are another thing!!! They do the minimum required by law. They have to post test results, but their "Notes" are little or non-existent. I suspect they don't have the resources to purchase the more expensive software and technical expertise or, perhaps the desire to provide notes to a visit. I utilized database technology a lot before retiring so I know this stuff should work.
