72510-1

LOINC code 72510-1 identifies "Performance rate Reporting Period Population Calculated". The "performance rate" is an aggregate measurement used in quality reporting. Specifically, it is a ratio of patients meeting numerator criteria for a particular quality measure, divided by patients in the denominator (accounting for exclusions and exceptions). Performance Rate is calculated using this formula: Performance Rate = (Numerator) / (Denominator - Denominator Exclusions - Denominator Exceptions) In this formula, the Denominator (target population) is a count of all the individuals who meet the measure's denominator criteria for which the target process, condition, event, and outcome is applicable. Denominator exclusions are a subset of the target population that meets the exclusion criteria. Denominator exceptions are another subset of the target population that are not in the exclusion criteria and not in the numerator that meet the exception criteria. For example, the numerator (NUMER) criteria for a given performance rate may include all patients with diabetes who received a dilated eye exam for diabetic retinopathy (N=75). The target population (denominator, DENOM) may include all patients aged 65 years and older with an active diagnosis of diabetes mellitus (N=150). An exclusion (EXCL) may be bilateral blindness (N=20) and the exception (EXCEP) would be the number of patients who have bed confinement status in a community where mobile eye-exam imaging is unavailable (N=5). Performance Rate = (NUMER) / (DENOM - EXCL - EXCEP) = (75)/(150-20-5) = 0.6

This code measures Performance rate in {Setting}^Population. It belongs to the DOC.QUALITY class in the LOINC classification.
