DX error by age groups

Does looking at other professions/activities help?

There is data suggesting Docs crash their private planes mor often, but then there may have been other factors e.g. The beachcraft bonanza which lost it's tail section was bought more frequently by physicians. With private planes there is a very cautious period followed by a confident period and then another cautious period. Crashes are low then higher then low again. So complex.

I would like to follow diagnostic errors by University/Hospital training as it related to to safety culture and a teaching course on safety (I think I read that only 50% of medical schools in the US have a formal safety course.

Also, are other countries better than the US - with many healthcare parameters the developed nations are far better.

Also, is there a litigation effect?

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.
