I guess I see this as somewhat different. These people are proactively choosing to maintain a relationship with a physician for an elective $50/month. I think the type of patient who wants a type of this relationship is the type who is going to solicit more than a single appointment per year; otherwise, why not just use what the current system gives us?

I could see something like this being useful for me; I'm constantly nagging my physician for different drugs I am triaging for a condition I'm dealing with. But, in that case, I wouldn't be the ideal patient for the physician. I wish this kind of thing could work, but I'm not sure how I see it working in practice, unless you move up market and charge more.
