There is good data to support this. Experienced doctors have poorer outcomes than newer doctors. I'm on mobile now but am happy to supply evidence later for anyone who'd like to see it.Doctors have this same problem with "bias". A lot of what they think they know from "experience" is just wrong and can be easily refuted by published studies. However, they persist in following their intuition with sometimes poor results for their patients.
The plural of anecdote is not data.
OK, sorry. Here you go.

A Freakonomics episode that covers other research (this entire 3-episode series is enjoyable, btw).
Saying that studies are biased but professional anecdotes aren't seems backward to me. Though, I may be unintentionally contorting what you've said, @tomas. Your example from the Forbes' article is a good example of how the media really casts doubt upon the validity of studies. They take marginal results from exploratory studies and headline their outcomes as truth. Reading the original study and methodology is almost always the best way to get a feel for the relevance of the conclusion.
I agree that professional opinion is worth consideration, but I do think it's always tainted with a plethora of biases. And so I'm not misconstrued, I include my own opinion in that categorization.
Apologies for misconstruing your message - as I mentioned, it was unintentional.You totally contorted what I said. Plz reread. I said a well conducted study was best basis but professional opinion not to be dismissed.
However, beware bias in and misuse of studies. As I read linked study, it appeared to conclude that probable cause of higher mortality was due to lower adherence to guidelines, probably because older physicians do not keep up with changes. It was cited in this thread as an example of where older doctors perform poorly due to experiential bias, intended to counter CPA's post. That is an incorrect interpretation and misuse of the study.
I think a lot of people start with an opinion, then reach for a study to support that opinion. Or worse yet, commission one. I appreciate a naked opinion advertised as such over an opinion dolled up with supporting studies hastily found via google. Having said that, big fan of fact checking, truth important, and data still reigns.
cool, glad I've got a young doctorApologies for misconstruing your message - as I mentioned, it was unintentional.
The linked study did not conclude cause. It was quasi-experimental (effectively an observational study) and concluded that there's a relationship between physician years of experience and length of stay/mortality. They pointed to a possibility of continuing education but also pointed out a number of interesting potential confounding factors in the study (older doctors may care for older patients). I cited the study as an example of where more experienced doctors have poorer outcomes. That seems to be consistent with the study's conclusion. For what it's worth, what you state above seems to me to be very similar. Experiential bias has a very close relationship to not adhering to new guidelines due to confidence levels in your existing bias. But that's just how it looks to me.
The Freakonomics piece referenced two studies that had similar conclusions. I believe all were observational, so no cause can be attributed in these studies.
For what it's worth, studies also support women doctors over male, and foreign-educated over domestic. I mean, if you're shopping on stats alone.cool, glad I've got a young doctor
