Sending medical images via MMS
I had to visit the ER after a cycling injury in fall 2014 and the doctor wanted to have a specialist check on something before stitching me up and sending me home. She took a few pictures with her smartphone and texted to him, which I'm pretty sure has to be a HIPAA violation in the US. I didn't care since the alternate was me waiting around an extra half hour while he drove to the hospital to examine me in person.
I'm sure the solution to this will be use of a camera to take photos that are passed to a computer then sent via secure email to a special app on a hospital issued smartphone or tablet the doctor will carry. Which despite being simple to do the "HIPAA approved" software will be marked up to an astronomical level since health care is a cost insensitive business. And that's the reason why health care costs will continue to spiral!
