Clinical trial overload

So, I'm just thrilled our medical spending is going to this, what about you?

A finding has to be reproducible to be believable. Only if different scientists in different places do the same study and get the same outcomes can physicians have confidence the finding is actually true. Only then is it ready to be put into clinical practice.

Nevertheless, one of medicine's most overlooked problems is the fact that some questions keep being asked over and over. Repeated tests of the same diagnostic study or treatment are a waste -- of time and money, and of volunteers' trust and self-sacrifice. Unnecessary clinical trials may also cost lives.

All this is leading some experts to ask a new question: "What part of 'yes' don't doctors understand?"

Great.
