Great point! That’s the way we are (should be) heading.
Big data *cough* (I don’t like that term) in health is one of the greatest frontiers in innovation with data. Open data initiatives etc are great. In the consumer health purchasing context, its certainly doable. In the broader health context where I am (Australia), many barriers still remain:
- Lack of integration and interoperability of health systems
- Legislative and privacy barriers to access to patient data
So yes, its a frontier, but none of the ‘good stuff' is actually available yet to leverage for any major health impact. Once this data becomes more open, perhaps through improvements in technology, legislation and streamlining personal consent, then the flood gates will open and I don’t doubt many a startup will make good use of the data.
