The preventive medicine myth.

“Researchers who have examined the effects of preventive care generally find that the added costs of widespread use of preventive services tend to exceed the savings from averted illness.”

That’s a quote from a recent letter penned by Director Doug Elmendorf of the Congressional Budget Office (CBO) to Congress. It’s just one more inconvenient truth for the Obama administration’s health care experiment, one of many that have already come from the CBO, including estimates to Congress that the proposed plans by the two different Democratic committee plans would add a $1 trillion and $1.6 trillion, respectively, to the national debt over just the first 10 years.

The latest CBO letter, the one which included the quote above, was in response to the Obama fallacy that preventative health care “saves money.” Saves for the one, yes. But saves for all? Not so.

Charles Krauthammer explains:

How can that be? If you prevent somebody from getting a heart attack, aren’t you necessarily saving money? The fallacy here is confusing the individual with society. For the individual, catching something early generally reduces later spending for that condition. But, explains Elmendorf, we don’t know in advance which patients are going to develop costly illnesses. To avert one case, “it is usually necessary to provide preventive care to many patients, most of whom would not have suffered that illness anyway.” And this costs society money that would not have been spent otherwise.

Think of it this way. Assume that a screening test for disease X costs $500 and finding it early averts $10,000 of costly treatment at a later stage. Are you saving money? Well, if one in 10 of those who are screened tests positive, society is saving $5,000. But if only one in 100 would get that disease, society is shelling out $40,000 more than it would without the preventive care.

That’s a hypothetical case. What’s the real-life actuality? In Obamaworld, as explained by the president in his Tuesday town hall, if we pour money into primary care for diabetics instead of giving surgeons “$30,000, $40,000, $50,000″ for a later amputation — a whopper that misrepresents the surgeon’s fee by a factor of at least 30 — “that will save us money.” Back on Earth, a rigorous study in the journal Circulation found that for cardiovascular diseases and diabetes, “if all the recommended prevention activities were applied with 100 percent success,” the prevention would cost almost 10 times as much as the savings, increasing the country’s total medical bill by 162 percent. That’s because prevention applied to large populations is very expensive, as shown by another report Elmendorf cites, a definitive review in the New England Journal of Medicine of hundreds of studies that found that more than 80 percent of preventive measures added to medical costs.

This doesn’t mean we shouldn’t be preventing illness. Of course we should. But in medicine, as in life, there is no free lunch. The idea that prevention is somehow intrinsically economically different from treatment — that treatment increases costs and prevention lowers them — is simply nonsense. Prevention is a wondrous good, but in the aggregate it costs society money. Nothing wrong with that. That’s the whole premise of medicine. Treating a heart attack or setting a broken leg also costs society. But we do it because it alleviates human suffering. Preventing a heart attack with statins or breast cancer with mammograms is costly. But we do it because it reduces human suffering.

However, prevention is not, as so widely advertised, healing on the cheap. It is not the magic bullet for health-care costs.
