        • 1.5 Measure Type
          1.7 Electronic Clinical Quality Measure (eCQM)
          1.8 Level Of Analysis
          1.20 Testing Data Sources
        • 1.14 Numerator

          The number of individuals in the denominator who receive at least one INR monitoring test during each 56-day interval with active warfarin therapy.

        • 1.15 Denominator

          Continuously enrolled individuals, at least 18 years of age at of the end of the measurement period, with at least 56 days of warfarin therapy during the measurement period.

        • Exclusions

          1. Individuals who are monitoring INR at home. These individuals are excluded because the claims associated with home INR monitoring are associated with up to four INR tests per claim. Therefore, a single claim for home INR monitoring would not be representative of a single INR test and would prohibit being able to distinguish if the home INR test was within the 56-day timeframe specified by the numerator of this measure.
          2. Individuals who have first or last warfarin claims with missing days’ supply.
