Yes, evidence-based medicine should be held to a higher standard because it's already been proven. When that's the case, we're talking about a different ballgame than what's not based in evidence. It's important to realize that. When it's a legitimate way to treat someone, we need to make sure doctors are taking it with the utmost seriousness.
Yes, evidence-based medicine can be held to a higher standard of care than traditional medicine, because it is unusual. Any time that someone does something that is unconventional, they should have the higher burden of proof to show that it is a sound practice. This is especially true in the helping professions, like medicine.
Evidence-Based medicine is based on statistics and therefore can not be held to a higher standard of care than traditional medicine. Practicing medicine has it's triumphs and failures no matter what the numbers say and each patient needs to be evaluated as an individual. Evidence-Based medicine is no different than traditional medicine.
I do not believe evidence-based medicine should be held to a higher standard of care than traditional medicine. I believe they are simply methods a doctor can use. Neither is better, they're just different. We shouldn't hold one above the other, they are both options when considering treatments and health issues.
