You are right about consumers being the key. My first 3 startup attempts were enterprise health... thought I knew insides of the system enough to be able to sell them on new tech/solutions that can change care for better.
Wrong. I found people willing to say they will adopt new tech, but fundamentally there was no incentive to actually take the steps.
To be fair, consumers are also not 100% motivated to be more accountable for their health. Delayed gratification may be a reason. But still, they will change faster than the establishment. And that may force the health establishment eventually.
Even well-researched, clinical trial based evidence from established research teams takes >decade to get entrenched into medical practice. Check this out: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1395794/
Sigh.
