Ratio of observed over predicted rates for diagnosis of dementia
-
Ratio of the number of patients 65 and older diagnosed with dementia attributed to a clinician or practice over the number of cases predicted based on the demographic profile of that clinician or practice. Once the clinician’s or practice’s O/E ratio (i.e., ratio of the observed and expected rates) is calculated, a computation of its associated standard error (SE) can be used to draw inference whether the O/E ratio is significantly different from 1 or not.CBE ID3672
