NUMERATOR / DENOMINATOR
- DENOMINATOR: Number of unique patients seen by the Eligible Physician (EP) or other eligible professional during the EHR reporting period.
- NUMERATOR: Number of unique patients in the denominator who have at least one entry (or an indication that the patient has no known medication allergies) recorded as structured data in their medication allergy list.
The resulting percentage (Numerator ÷ Denominator) must be more than 80 percent in order for an EP to meet this measure.
- For patients with no active medication allergies, an entry must still be made to the active medication allergy list indicating that there are no active medication allergies.
- An EP is not required to update this list at every contact with the patient. The measure ensures that the EP has not ignored having a medication allergy list for patients seen during the EHR reporting period and that at least one piece of information on medication allergies is presented to the EP. The EP can then use their judgment in deciding what further probing or updating may be required given the clinical circumstances at hand.
