although I haven't read too much about healthcare, I decided to get back into casual reading and I've found Relman's "second opinion" to be pretty good in terms of history, current state, and the author's view on how to change it. kings hit it on the button when saying that it will prepare you for interviews.
it is a bit biased in terms of massive reform, but it's easily arguable that drastic steps need to be taken so that there aren't kids like me who can't track down their immunization records because they're split across 5 doctors who happened to be the lowest-cost-to-uninsured providers. Of course, I don't think that you'll find many doctors who publish books that say "we dont need to change the healthcare system." Relman makes sure to tell you that the "it will work itself out" camp are all economists and/or special interest groups.
It's a very interesting (and applicable) topic. Looking forward to seeing more recommendations on what I should read next.
