2026 US Quality Core Implementation Guide, published by Office of the National Coordinator for Health Information Technology (ONC). This guide is not an authorized publication; it is the continuous build for version 0.5.0 built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/FHIR/us-quality-core/ and changes regularly. See the Directory of published versions

## Resource Profile: US Quality Core MedicationAdministration

Official URL: http://fhir.org/guides/onc/us-quality-core/StructureDefinition/us-quality-core-medicationadministration | Version: 0.5.0
Draft as of 2026-05-15 | Computable Name: USQualityCoreMedicationAdministration

Profile of MedicationAdministration for decision support/quality metrics. Defines the core set of elements and extensions for quality rule and measure authors.

Usage

To create an expression specifically requesting information that a MedicationAdministration intentionally did not occur for a medical, patient or system reason, use the profile USQualityCore MedicationAdministration Not Done.

The following example illustrates the accessing MedicationAdministration data:

    define "Low Dose Unfractionated Heparin Administration":
      ["MedicationAdministration": medication in "Low Dose Unfractionated Heparin for VTE Prophylaxis"] VTEMedication
        where VTEMedication.status = 'completed'

See the patterns page for implementation and usage patterns.

### Examples

Inhalant Example
Cumulative Duration Example

USCDI+ Quality Elements:

- status: (USCDI+ Quality) in-progress | on-hold | completed | entered-in-error | stopped | unknown
- medication[x]: (USCDI+ Quality) What was administered
- effective[x]: (USCDI+ Quality) Start and end time of administration
- dosage: (USCDI+ Quality)
- dosage.route: (USCDI+ Quality) Path of substance into body
- dosage.dose: (USCDI+ Quality) Amount of medication per dose

Usages:

- Refer to this Profile: US Quality Core AdverseEvent
- Examples for this Profile: MedicationAdministration/cmd-example and MedicationAdministration/example
- CapabilityStatements using this Profile: US Quality Core Client CapabilityStatement and US Quality Core Server CapabilityStatement
