Information asymmetries are a huge problem in "market solutions" and there's a huge one here: doctors have 8+ years of medical training and most patients....don't. It's going to be very hard for many people to second-guess a doctor's recommendation or estimate the expected value of decisions.
In a non-emergency situation, you can certainly try to read up on your own, but the medical literature is not always easy to interpret. A friend of mine asked for advice after he was diagnosed with Parkinson's Disease. Despite having a PhD in neuroscience and working as a researcher in a PD Center of Excellence, I had a really hard time making a recommendation. (Neuro conditions are particularly hard, but this is also possibly the best-case match with my experience).
