This is a follow-up visit, not an initial visit. For example, I just saw a doctor and told him everything that I could have told him by email or a question-assisted form. He didn't touch me and didn't ask me any questions. Plus, he had the benefit of seeing a report from a physical therapist so he could see a 3rd party's assessment of my situation. During these kind of follow-up visits, there is no reason that he could do one of 3 things if I had simply emailed him: 1) told me to stay the course and refill my script, 2) told me to come in for a procedure, or 3) ask that I come in because it was hard to access the situation.
Obviously different situations require different reactions. In my particular case, an email followup would have made sense. In other people's cases, the health issue may be too severe that a physical followup would be warranted no matter what.
In another personal experience, I had gone to a doctor where he didn't accept any insurance and only accepted out of pocket. In this example, the doctor was very accessible by email. I didn't need to meet with the doctor sooner than when I was scheduled for the revisit.
Healthcare is broken and unfortunately, I'm not sure it will be fixed until the doctors see us patients as the customers instead of the health insurance companies or governmental health programs.
