A lot of innovations and medical technology advancements have been introduced these days that are meant to improve and develop better ways of diagnosing illnesses and diseases as well as treatment and prevention.
Surprisingly, several research have found that some medical practices, old or new – are actually useless and are not actually effective, even more worse to patients. Still, several doctors persist to continue using these practices.
According to a review of each issue from The New England Journal of Medicine by several scientists from 2001 through 2010, they surprisingly found 363 practices that were a clinically established medical practice, even these days. Among these 363 clinically established practices, they found out that 146 of them were actually useless or could even be worse. The original report can be found here.
In a more detailed report, they simply found out that among all the clinically established medical procedures, a stunning 40% were ineffective, 38% were beneficial, and the remaining 22% were unknown or have found no benefits, nor harmful effects.
Often, doctors persist with medical procedures even though it lacks evidence about its effectiveness and worthiness on diagnosing, treating and preventing diseases or illnesses. “They all sound good if you talk about the mechanism. You have cholesterol-clogged arteries, it makes sense that if you open them up it will help. But when that was studied, it didn’t improve survival” said Dr. Prasad, the chief fellow in medical oncology at the National Cancer Institute.
He added, “They tend to gravitate toward the nuts and bolts — what does it do, how does it work?But the real question is: Does it work? What evidence is there that it does what you say it does? What trials show that it actually works? You shouldn’t ask how does it work, but whether it works at all.”
