Portable deceives including cell phones can be HIPPA compliant. Maybe they look at it if it isn't broke why fix it.
I dont know if it's completely broke, but it does leave lots of room for improvement. We know communication is key to running any smooth operation, the better your platform to communicate is the higher your odds are of performing better.

And I would imagine malpractice insurance would go down as they can better track the communication resulting in less frivolous law suits.
