Procedures live on even after they’ve been proved ineffective. It can lead to harms and wasted resources. Part of a doctor’s tool kit is learning new things, but also unlearning some things.
The second part may be harder than the first. We know it can be hard to persuade physicians to do some things that have proven benefits, such as monitor blood pressure or keep patients on anticoagulants. But it might be even harder to get them to stop doing things.
In May, a systematic review in JAMA Pediatrics looked at the medical literature related to overuse in pediatric care published in 2016. The articles were ranked by the quality of methods; the magnitude of potential harm to patients from overuse; and the potential number of children that might be harmed. In 2016 alone, studies were published that showed that we still recommend that children consume commercial rehydration drinks (like Pedialyte), which cost more, when their drink of choice would do.
We give antidepressants to children too often. We induce deliveries too early, instead of waiting for labor to kick in naturally, which is associated with developmental issues in children born that way. We get X-rays of ankles looking for injuries we almost never find.
And although there’s almost no evidence that hydrolyzed formulas do anything to prevent allergic or autoimmune disease, they’re still recommended in many guidelines.
