11.2 Resource MedicationAdministration - Content

Pharmacy Work Group Maturity Level : 2   Trial Use Compartments : Device , Encounter , Patient , Practitioner , RelatedPerson

Describes the event of a patient consuming or otherwise being administered a medication. This may be as simple as swallowing a tablet or it may be a long running infusion. Related resources tie this event to the authorizing prescription, and the specific encounter between patient and health care practitioner.

11.2.1 Scope and Usage

This resource covers the administration of all medications and vaccines. Please refer to the Immunization Resource/Profile for the treatment of vaccines. It will principally be used within care settings (including inpatient) to record the capture of medication administrations, including self-administrations of oral medications, injections, intra-venous adjustments, etc. It can also be used in out-patient outpatient settings to record allergy shots and other non-immunization administrations. In some cases it might be used for home-health reporting, such as recording self-administered or even device-administered insulin.

MedicationAdministration is an event resource from a FHIR workflow perspective - see Workflow Event

11.2.2 Boundaries and Relationships

The Medication domain includes a number of related resources

MedicationRequest An order for both supply of the medication and the instructions for administration of the medicine to a patient.
MedicationDispense Provision of a supply of a medication with the intention that it is subsequently consumed by a patient (usually in response to a prescription).
MedicationAdministration When a patient actually consumes a medicine, or it is otherwise administered to them
MedicationStatement This is a record of a medication being taken by a patient or that a medication has been given to a patient, where the record is the result of a report from the patient or another clinician. A medication statement is not a part of the prescribe->dispense->administer sequence, but is a report that such a sequence (or at least a part of it) did take place, resulting in a belief that the patient has received a particular medication.

MedicationAdministration is intended for tracking the administration of non-vaccine medications. Administration of vaccines is intended to be handled using the Immunization resource. Some systems treat immunizations in the same way as any other medication administration. Such systems SHOULD use an immunization resource to represent these. If systems need to use a MedicationAdministration resource to capture vaccinations for workflow or other reasons, they SHOULD also create and expose an equivalent Immunization instance.

This resource is referenced by AdverseEvent , ChargeItem , MedicationStatement , Observation and Procedure

Typically the rate for an infusion e.g. 100 ml per 1 hour or 100 ml/hr. May also be expressed as a rate per unit of time e.g. 500 ml per 2 hours.

11.2.3.1 Terminology Bindings

Path Definition Type Reference

MedicationAdministration.medication[x] Codes identifying substance or product that can be administered. Example SNOMED CT Medication Codes
MedicationAdministration.performer.function A code describing the role an individual played in administering the medication Example MedicationAdministrationPerformerFunction
MedicationAdministration.reasonNotGiven MedicationAdministration.statusReason A set of codes indicating the reason why the MedicationAdministration is negated. Example SNOMED CT Reason Medication Not Given Codes

MedicationAdministration.dosage.method A coded concept describing the technique by which the medicine is administered. Example SNOMED CT Administration Method Codes

11.2.3.2 Constraints

  • mad-1 : On MedicationAdministration.dosage: SHALL have at least one of dosage.dose or dosage.rate[x] ( expression on MedicationAdministration.dosage: dose.exists() or rate.exists() )
    • mad-2 : Reason not given is only permitted if NotGiven is true ( expression : reasonNotGiven.empty() or notGiven = true ) mad-3 : Reason given is only permitted if NotGiven is false ( expression : reasonCode.empty() or notGiven.empty() or notGiven = 'false' )

11.2.4 Known Issues

Issue Comments
Medication Resource A medication will typically be referred to by means of a code drawn from a suitable medication terminology. However, on occasion a product will be required for which the "recipe" "recipe" must be specified. This implies a requirement to deal with a choice of either a code or a much more complete resource.
Currently that resource has not been created.
Contrast Media Is this resource adequate for administering contrast media to a patient?
Author (accountability) Authorship (and any other accountability) is assumed to be dealt with by the standard FHIR methods.
