Note that this doesn't solve a problem that providers have right now.

For people with serious medical conditions that need to communicate that to EMS, we have physical medalert bracelets that can tell healthcare providers that you have diabetes or epelipsy. That technology works even if your provider doesn't have power or reliable internet.

Most patient provider interactions don't require history transmission because you're at a scheduled office visit or your in emergency care at a facility that is part of your giant local health network. In those cases, providers can look up your name (that they can get from your wallet even if you're not conscious) in their database and find all they need. They don't have to worry about synchronizing data with arbitrary providers and trying to remap their ontologies or deal with lossy translations.

The number of cases where providers need fine grained history information for people that they've never treated before and they need it right NOW and can't afford to wait is...very small relative to the volume of patients treated. I mean, if you've been shot in the chest, the ER is going to focus on keeping you from bleeding to death rather than poring through a history to note that you're allergic to ragweed pollen, have slightly elevated blood pressure and fractured your tibia 8 years ago.
