11.2 Resource MedicationAdministration - Content

Pharmacy Work Group Maturity Level : 2   Trial Use Security Category : Patient 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 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 MedicationUsage 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.

11.2.3 References

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

This resource implements the Event pattern.

(Strength=Example) first captured in the record - potentially significantly after the occurrence of the event ReasonMedicationGivenCodes recorded ?? » : dateTime [0..1] A code, Condition or observation that supports why the medication was administered reasonReference reason : Reference DataType [0..*] « Condition | Observation | DiagnosticReport ; A set of codes indicating the reason why the MedicationAdministration was made. (Strength=Example) DiagnosticReport ReasonMedicationGivenCodes ?? » The original request, instruction or authority to perform the administration request : Reference [0..1] « MedicationRequest » The device used in administering the medication to the patient. For example, a particular infusion pump device : Reference [0..*] « Device » Extra information about the medication administration that is not conveyed by the other attributes note : Annotation [0..*] A summary of the events of interest that have occurred, such as when the administration was verified eventHistory : Reference [0..*] « Provenance » Performer Distinguishes the type of involvement of the performer in the medication administration function : CodeableConcept [0..1] « A code describing the role an individual played in administering the medication.

When coded dosage is present, the free text dosage may still be present for display to humans. The dosage instructions should reflect the dosage of the medication that was administered text : string [0..1] A coded specification of the anatomic site where the medication first entered the body. For example, "left arm" site : CodeableConcept [0..1] « A coded concept describing the site location the medicine enters into or onto the body.

For example, topical, intravenous, etc route : CodeableConcept [0..1] « A coded concept describing the route or physiological path of administration of a therapeutic agent into or onto the body of a subject. (Strength=Example) SNOMEDCTRouteCodes ?? » A coded value indicating the method by which the medication is intended to be or was introduced into or on the body. This attribute will most often NOT be populated. It is most commonly used for injections. For example, Slow Push, Deep IV method : CodeableConcept [0..1] « A coded concept describing the technique by which the medicine is administered. (Strength=Example) SNOMEDCTAdministrationMethodC... ?? » The amount of the medication given at one administration event. Use this value when the administration is essentially an instantaneous event such as a swallowing a tablet or giving an injection dose : Quantity ( SimpleQuantity ) [0..1] Identifies the speed with which the medication was or will be introduced into the patient. 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. Other examples: 200 mcg/min or 200 mcg/1 minute; 1 liter/8 hours rate[x] : Type DataType [0..1] « Ratio | Quantity ( SimpleQuantity ) » Indicates who or what performed the medication administration and how they were involved performer [0..*] Describes the medication dosage information details e.g. dose, rate, site, route, etc dosage [0..1]

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.
