Since I started following cryptocurrencies, I have not seen yet a promising ICO or existing project that is aimed with Health Care. It seems this is a bit of a challenge, as personal medical records might become public if put in an online ledger.
There have been several icos that were related to healthcare in fact I remember at least two that happened in the last year and for some time they were successful in the market but I never heard anything about being successful at what they promised, you need to be very careful because when it comes to healthcare there are a lot of regulations that you need to follow and that makes it a difficult market to succeed.
