Two things to take home…
And some correct places
to find them, on this and the subsequent page (NOT the
pages mentioned in class)…
The improvement in the
use of special procedures (especially immunohistochemistry
(“Immunopath”), which was unheard of before 1985, has
helped in making the diagnosis more accurate, but the fall in the autopsy rate at the same time has just about cancelled that out.
Here we see an
example. In the light area (two yellow
rows), we see that diagnostic uncertainty was doubled
when there was no autopsy in the earlier time period
and “accuracy” of diagnosis about 10% more.
In the later period, virtually the same thing
was true, even though the overall figures were slightly better in each cell.
