This sounds like a great project. I love the idea of building technology for healthcare in a small, controlled, active care environment, and then scaling those tools to a larger audience.
The bigger issue in healthcare IMHO is that the American healthcare model, while hugely inefficient, seems to be the system that best incentivizes innovation. We pay 10x what Sweden pays for medical devices, but the US market is the only reason those device companies can be profitable. If we move to a single-payer system in the US, the economic incentives for innovation go way down.
If someone can figure out how to lower costs, while still providing a profitable market in which drug and device companies can innovate, we'll all benefit.
