David Leonhardt on the imperative of reducing unnecessary medical care:

We want the best possible care, no matter what. Yet we often do not get it because the current system tends to deliver more care even when it means worse care.
It’s not just CT scans. Caesarean births have become more common, with little benefit to babies and significant burden to mothers. Men who would never have died from prostate cancer have been treated for it and left incontinent or impotent. Cardiac stenting and bypasses, with all their side effects, have become popular partly because people believe they reduce heart attacks. For many patients, the evidence suggests, that’s not true.
Advocates for less intensive medicine have been too timid about all this. They often come across as bean counters, while the try-anything crowd occupies the moral high ground. The reality, though, is that unnecessary care causes a lot of pain and even death.
