Good writing bt not feasible yet. Imagine from the land of plenty, UK, the gvt spent over £13 billion trying have a centralised health database and still failed: http://www.telegraph.co.uk/hea....
What we need first is our gvt departments to be digitised. That means people losing jobs and others with tech motive gaining new jobs. We all kno that this is going face stiff opposition from those benefiting from long queues and public suffering
Then we need to provide infrastructure like connecting hospitals together and maybe GPs depending with security and vetting in place.
