Defining Attributes

Definition

Ratio of the number of patients 65 and older diagnosed with mild cognitive impairment attributed to a clinician or practice over the number 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.

Numerator

Number of individuals aged 65 and older under the care of a clinician or practice who are diagnosed with mild cognitive impairment.

Denominator

Predicted number of individuals aged 65 and older under the care of a clinician or practice with mild cognitive impairment based on the demographic profile of the respective clinician or practice. Limit reporting to clinicians and practices with at least 25 attributed patients per CMS' guidance to ensure stability of measure results.
