11.2 Resource MedicationAdministration - Content

Pharmacy Work GroupMaturity Level: 2 Trial UseCompartments: 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.

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 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

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

MedicationAdministration (DomainResource)External identifier - FHIR will generate its own internal identifiers (probably URLs) which do not need to be explicitly managed by the resource. The identifier here is one that would be used by another non-FHIR system - for example an automated medication pump would provide a record each time it operated; an administration while the patient was off the ward might be made with a different system and entered after the event.

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" 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.

Search parameters for this resource. The common parameters also apply. See Searching for more information about searching in REST, messaging, and services.
