prescriber

The person who ordered the prescription.

The prescriber attribute references the QDM entities (Patient, Care Partner, Practitioner, or Organization) and any or all of the attributes of the respective QDM entity. For example, to reference that a physician who prescribed a medication is the same person who was the primary participant in an Encounter and assure the physician’s specialty meets the measures requirements, the eCQM can use the Practitioner entity and its attributes.

Should the eCQM choose to reference a physician practice or a hospital, the performer can reference the Organization entity and indicate the identifier and/or the organization type.

[See Section 2.6 for description of Entities].

The CQL can specify which identifier the measure expects to be used (e.g., NPI or Tax Identifier Number) or it can avoid referencing an identifier to allow the implementing organization or practice to use its own identifier.
