Adam Bosworth of Google gave a speech at the "Connecting Americans to Their Health Care" conference citing their ongoing efforts in the healthcare industry. They have already started giving patients and caregivers easier access to the information found on the Internet through Google Co-op, but that is a very small piece of the pie.
His speech got more into what he calls your "Health URL" that gives patients control of their personal health data. It allows them to share important information with those that can use it to provide better care.
Let me add something to the suggestion box. I really like the idea of a "Health URL" -- it is easily accessible by caregivers as long as they are invited. Why not issue "Google Health Cards" displaying a private URL that doesn't require a login. To reveal the URL, someone would have to scratch the coating (like a scratch ticket).
If someone is carrying their card in their wallet or purse, emergency crews would have access to your personal health record -- something that could potentially save your life. People worried about their privacy might not want to carry these cards around with them, forcing some to choose between health and privacy -- for me that's not a difficult decision.
