Thanks for your feedback (worth more than two cents, I'm sure 😄).
I'm not on the Mayo patient portal, so I can't speak to that one, but it's nice to hear about the user interface testing. Does the testing that you've been involved in include both healthcare workers and patients who use the platform? That would be helpful so that both "sides" could see and understand the needs of each other.
My hospital portal is MyChart which might not work exactly the same way as Mayo's Patient Portal. But my hospital also has focus groups that analyze the portal. I know that patients are part of the focus group but not sure about the healthcare professionals, as I never participated in one. Overall, the portal is helpful, and I definitely use it all the time. I'm glad to have it available to me, but there are a few aspects that are not patient-user friendly. As far as I know, when I contact them, they only offer technical support or correct misinformaton in my record. Thanks, again, for your feedback. It's very helpful. You have caused me to consider signing up the next time they have another focus group.
