In a recent Wired magazine article, "Gadgets Like Fitbit Are Remaking How Doctors Treat You," I was reminded of the quote from the TV show House. The lead character in the show, Dr. Gregory House, M.D., is portrayed as a genius of diagnostic medicine who frequently quips, "Everybody lies." He is generally referring to patients who are being asked difficult personal questions, but the Wired article caused me to consider if that was true about patients in general. For example, do patients listen when a doctor prescribes rest? Does the patient know if they're lying? Is one man's "rest" the same as another? Could activity trackers and heart rate monitors really provide accurate data to the doctors? Could this data be reviewed by the doctor and eliminate follow-up appointments? Does the combination of a sensor-laden super-computer in our pocket and an activity tracker on our wrist allow us to provide real information to our doctors?
