 What excites me is the power of an integrated system and the ability for research to make a real difference to our members. The Vioxx story is really a good illustration of what's possible. This was a case where there was some reason to be concerned about this medication that people were taking for pain. The Food and Drug Administration came to us and said, you have great data. Can we take a look in your data to see if there really is a problem here? We discovered, in fact, there was this increased risk of heart attacks for people who were on this medication. Within 48 hours, we had everybody off that drug that had been on it. How did we do that? Well, we have electronic records. We know what medications people are taking. We had ways to get in touch with our patients, phone numbers, email addresses. That idea of being able to act on information carefully, that's incredible.
