DX error by age groups

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.
