I have long held the belief that health information technology will be harnessed to truly improve our health. There may be hiccups along the way, but one day we will be able to have our health information available where and when we need it, in a manner that will make a difference for far many more of us — whether patients, physicians, or those interested in maintaining and/or improving their health — than is the case today. As physicians, we are going to have to learn how to incorporate this data into the everyday care of our patients, especially in primary care.
I am also a believer — as are many others — that we will develop tools that will be able to monitor our important health-related behaviors as we are, where we are, in a non-intrusive way so that the process becomes seamless. Think about monitoring blood pressure, weight, blood sugar or even simple (and perhaps much more complex) blood tests through biometric wearable monitors. I would even go so far as to predict wearable devices which will tell us if we have cancer, and if we do how we are responding to treatment by measuring circulating cells or even DNA fragments. But some of these ideas could easily be termed “phantasmagorical” and probably a long way off.
