As you know I’ve been following this number for 10 years (not to mention working with and at Harris during part of that time), and the increase in the last few years has been remarkable. After all the fast pace growth in the internet was in the 1990s not in the 2000s, yet its use for health care continues to increase.
And talking about cyberchondria, I had severe chest pain about a month ago that felt pretty bad while I was out of state. I searched on the web for chest pain, confirmed that I had 3 of 4 symptoms of a heart attack and got myself to a doctor rapidly. The EKG was negative, but of course had there been no Internet I might not have bothered and I might have ignored a heart attack or arrhythmia. Presumably that’s not the preferred use of health online, but it really helped me.
