Bernard Keane got a bit excited yesterday, thinking he was onto a major myth-bust: that prevention may not be better than cure. Citing a New England Journal of Medicine review of prevention’s ability to cost save, he faithfully reported the finding that "Although some preventive measures do save money, the vast majority reviewed in the health economics literature do not."

Now who ever thought that by simply uttering the magic word "prevention" that any intervention would either work (prevent disease or save lives) or save money? Just like treatments, prevention has its fair share of useless fads and non-evidence based enthusiasms.
