The New York Times: Why Doctors Still Offer Treatments That May Not Help by Austin Frakt
Even when we learn something doesn’t make us better, it’s hard to get the system to stop doing it. It takes years or even decades to reverse medical convention. Some practitioners cling to weak evidence of effectiveness even when strong evidence of lack of effectiveness exists.
This is not unique to clinical medicine. It exists in health policy, too. Much of what we do lacks evidence; and even when evidence mounts that a policy is ineffective, our political system often caters to invested stakeholders who benefit from it.
An honest assessment of the state of science behind clinical practice and health policy is humbling. Though many things we do and pay for are effective, there is a lot we don’t know. That’s inevitable. What isn’t inevitable — and where the real problems lie — is assuming, without evidence, that something works.
