One suspects Sharon Begley was trying to make a not-so-subtle argument for expert — i.e., government — rationing of health care with her latest Newsweek cover story.

They are applying to their personal lives a message they have become increasingly vocal about in their roles as biomedical researchers and doctors: more health care often means worse health. “There are many areas of medicine where not testing, not imaging, and not treating actually result in better health outcomes,” Redberg says. In other words, “less is more.” Archives, which is owned by the American Medical Association, has been publishing study after study about tests and treatments that do more harm than good.

That less health care can lead to better health and, conversely, that more health care can harm health, runs counter to most patients’ conviction that screenings and treatments are inherently beneficial. That belief is fueled by the flood of new technologies and drugs that have reached the market in the past two or three decades, promising to prevent disease and extend life. Most of us wouldn’t think twice if our doctor offered a test that has the power to expose a lurking tumor, or a clogged artery, or a heart arrhythmia. Better to know—and get treated—than to take any risks, the reasoning goes.

In fact, for many otherwise healthy people, tests often lead to more tests, which can lead to interventions based on a possible problem that may have gone away on its own or ultimately proved harmless.

Left unexplored is the best way to limit unnecessary medical procedures: Put policies in place to promote consumer-driven health care.
