In 1854, Dr. John Snow started treating victims of cholera in London. More than 500 people died in the first week the disease surfaced. Desperate to figure out what was causing the epidemic, he worked round the clock for days to hand-draw a map containing the location of all the homes of the sick and dying, and he realized that everyone who was sick got their water from the same well. He persuaded local officials to remove the well pump handle, and the epidemic stopped.
Today, a high school student using Google Maps could probably draw that same map in a few minutes by combining death notice addresses and well locations readily available on the Internet.
Data mining of accumulating electronic health records across platforms will reframe the healthcare debate.
