A QDM attribute provides specific detail about a QDM datatype.

Performance/Reporting Period
QDM Definition (QDM Version 5.5 Guidance Update):

The person who ordered the prescription.

The prescriber attribute references the new 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.

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