72509-3

LOINC code 72509-3 identifies "Reporting rate Reporting Period Population Calculated". The "reporting rate" is an aggregate measurement used in quality reporting. Specifically, it is a ratio of of patients in the denominator (target population) who fall into one of the other subpopulations. Reporting rate is calculated using this formula: Reporting Rate = (Numerator + Denominator Exclusion + Denominator Exceptions)/(Denominator) In this formula, the Numerator is an aggregate of patients who meet the criteria for a particular quality measure. Denominator exclusions are a subset of the target population (denominator) that meets the exclusion criteria for the quality measure. 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. The denominator 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. For example, the numerator (NUMER) for a given reporting rate may include all patients with diabetes who received a dilated eye exam for diabetic retinopathy (N=75). 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). The target population (denominator, DENOM) may include all patients aged 65 years and older with an active diagnosis of diabetes mellitus (N=150). Reporting Rate = (NUMER + DENOM EXCL + DENOM EXCEP)/(DENOM) = (75+20+5)/(150) = 0.67

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