I'm using the KP health system. Its pretty awesome. Everything in integrated. I can use the website or phone app to check any of my test results. I can message my doctor for a e-consult at no extra cost. They usually reply within half day. I can book most appointments online. If I went to a specialist, I can continue messaging them in the future. And since the doctor is gate keeper, you just need them to approve a procedure and it will happen.
