An attempt to model activity of individual histopathologists or depart
ments is illustrated, in which specimen numbers and types are weighted
to produce an overall Kim unit (KU) activity. By cross referencing th
is numerical score against individual pathologists and clinicians, it
is not only possible to interrogate departmental activity retrospectiv
ely, but also to predict and cost the impact of any change in service.
The advantages over Welcans and Korner Units are illustrated.
