Wouldn't it be great if consumers could access all their personal medical records quickly and share them with doctors, family members and others they trust?

This could lead to revolutionary changes in patient outcomes with less bureaucracy and fewer medical mistakes and unnecessary tests.

In recent weeks, major announcements by Apple and Google, plus a new healthcare alliance by Amazon, Berkshire Hathaway and JP Morgan Chase are signs of accelerated change.

No one is better equipped to interpret these changes than physician and entrepreneur, Dr. Joe Habboushe, our expert guest on this episode of "How Do We Fix It?"

Joe is CEO of MD Calc--a leading online medical tool for clinical decisions by physicians-- and a specialist in emergency medicine at NYU Medical Center in New York.

On this show we look at opportunities and hazards in the changing relationship between doctors and parents. We discuss privacy concerns and examine how data, smartphone apps and other innovations could reduce costs and lead to better diagnosis of common illnesses and physical ailments.
