I think what you will find interesting, and what immediately leads to a sort of mindset shift - which is required to fully grasp the holistic approach that SX follows - is that SX defines #SocialNetworking as follows:
"Any direct or indirect human interaction between people."
Period. That's it. It encompasses that vast scope, which includes both our offline and online worlds (handy, to focus on that peopleverse).
A healthcare system is a complex mulitplayer environment, where many people in different stakeholder roles work with sensitive data. That is the technical perspective.
On the social side, it is a social network, for which you can apply SX as the evolutionary solution design methodology.
