Today my medical skepticism appears as this month’s lead essay, "Cut Medicine In Half," at CATO Unbound. Distinguished health economists are scheduled to comment:  Harvard’s David Cutler on Wednesday, RAND’s Dana Goldman on Friday, and Stanford’s Alan Garber next Monday.  Open discussion begins next Wednesday.  Also, I just learned that next Tuesday a book with a related thesis, Overtreated, will appear. My essay begins: 

Car inspections and repairs take a small fraction of our total spending on cars, gas, roads, and parking. But imagine that we were so terrified of accidents due to faulty cars that we spent most of our automotive budget having our cars inspected and adjusted every week by Ph.D. car experts.  Obsessed by the fear of not finding a defect that might cause an accident, imagine we made sure inspections were heavily regulated and subsidized by government. To feed this obsession, imagine we skimped on spending to make safer roads, cars, and driving patterns, and our constant disassembling and reassembling of cars introduced nearly as many defects as it eliminated.  This is something like our relation to medicine today. …

The right says governments produce a much inferior baby.  I say: cut the medical baby in half, dollar-wise, and throw half away! …

Our main problem in health policy is a huge overemphasis on medicine.  The U.S. spends one sixth of national income on medicine, more than on all manufacturing.  But health policy experts know that we see at best only weak aggregate relations between health and medicine, in contrast to apparently strong aggregate relations between health and many other factors, such as exercise, diet, sleep, smoking, pollution, climate, and social status. Cutting half of medical spending would seem to cost little in health, and yet would free up vast resources for other health and utility gains. …
