Definition
The ratio of the number of patients, who are attributed to a clinician or practice, with a diagnosis of any stage of cognitive impairment over the expected number of cases based on a predictive model. 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.
