I thought the way Eta thought.  Interesting....and interesting word
confusion.

    eg, "I cannot recommend this person highly enough"     "you will be
lucky if you get this person to work for you."

I did mean by patient age but realise that by practitioner age is also an
interesting question.

Did you mean by patient age or practitioner age?

I have been tracking exactly this question for some time.. I have located
probably 15 studies that address the question. First of all, it's easy to
show a strong positive relationship with residency training, which is not
the case if you look at measures like adherence to guidelines, ABIM
performance etc. But beyond residency it's more tricky.I have not summarized
the data quantitatively as yet, but I think the best guess is that there is
a small negative relation between age and dx error, typically around -0.1.
And many outliers. In one study we did with elite internists, the best
performer was 65, and the worst performer was 65.  

 

But a tantalizing possibility is that it may follow the "10,000" hour curve
and be curvilinear, peaking at around 45. There's just not enough data to
find this.

Hi to the new group.

 

Does anybody know of any studies that show dx error by age group?

 

Many thanks
