Measure Calculation Example

Dr. Ige has 100 patients diagnosed with isolated lower back pain between January 1 and December 31. Twelve patients were diagnosed with sciatica and two patients reported radicular symptoms. They meet exclusions and are removed from the initial population. (100-(12+2)=86. This is the denominator.

Of the 86 patients, 12 had an EMG for diagnosis of isolated lower back pain. The numerator is 12.

Quality of patient care = 12/(100-(12+2)). Dr. Ige has a score of 13.95% for this measure. A lower score indicates better care for this measure.
