This profile defines the UK constraints and extensions on the International FHIR resource MedicationAdministration.


Profile_Purpose

The purpose of this profile is to describe 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.

Detailed Descriptions

MedicationAdministration
DefinitionDescribes 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.

MedicationAdministration.id
DefinitionThe logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes.
Cardinality0...1
Typestring
SummaryTrue
Comments

The only time that a resource does not have an id is when it is being submitted to the server using a create operation.

MedicationAdministration.meta
DefinitionThe metadata about the resource. This is content that is maintained by the infrastructure. Changes to the content might not always be associated with version changes to the resource.
Cardinality0...1
TypeMeta
SummaryTrue
Invariants
  • ele-1: All FHIR elements must have a @value or children
    hasValue() or (children().count() > id.count())
Mappings
  • rim: n/a
  • rim: N/A
MedicationAdministration.implicitRules
DefinitionA reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc.
Cardinality0...1
Typeuri
ModifierTrue
SummaryTrue
Comments

Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element. Often, when used, the URL is a reference to an implementation guide that defines these special rules as part of it's narrative along with other profiles, value sets, etc.

Invariants
  • ele-1: All FHIR elements must have a @value or children
    hasValue() or (children().count() > id.count())
Mappings

MedicationAdministration.language
DefinitionThe base language in which the resource is written.
Cardinality0...1
Typecode
Binding

A human language.

CommonLanguages (preferred)
Comments

Language is provided to support indexing and accessibility (typically, services such as text to speech use the language tag). The html language tag in the narrative applies to the narrative. The language tag on the resource may be used to specify the language of other presentations generated from the data in the resource. Not all the content has to be in the base language. The Resource.language should not be assumed to apply to the narrative automatically. If a language is specified, it should it also be specified on the div element in the html (see rules in HTML5 for information about the relationship between xml:lang and the html lang attribute).

Invariants
  • ele-1: All FHIR elements must have a @value or children
    hasValue() or (children().count() > id.count())
Mappings
  • rim: n/a
MedicationAdministration.text
DefinitionA human-readable narrative that contains a summary of the resource and can be used to represent the content of the resource to a human. The narrative need not encode all the structured data, but is required to contain sufficient detail to make it "clinically safe" for a human to just read the narrative. Resource definitions may define what content should be represented in the narrative to ensure clinical safety.
Cardinality0...1
TypeNarrative
Aliasnarrative, html, xhtml, display
Comments

Contained resources do not have narrative. Resources that are not contained SHOULD have a narrative. In some cases, a resource may only have text with little or no additional discrete data (as long as all minOccurs=1 elements are satisfied). This may be necessary for data from legacy systems where information is captured as a "text blob" or where text is additionally entered raw or narrated and encoded information is added later.

MedicationAdministration.contained
DefinitionThese resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, and nor can they have their own independent transaction scope.
Cardinality0...*
TypeResource
Aliasinline resources, anonymous resources, contained resources
Comments

This should never be done when the content can be identified properly, as once identification is lost, it is extremely difficult (and context dependent) to restore it again. Contained resources may have profiles and tags In their meta elements, but SHALL NOT have security labels.

Mappings
  • rim: Entity. Role, or Act
  • rim: N/A
MedicationAdministration.extension
DefinitionMay be used to represent additional information that is not part of the basic definition of the resource. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.
Cardinality0...*
TypeExtension
Aliasextensions, user content
Comments

There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

MedicationAdministration.modifierExtension
DefinitionMay be used to represent additional information that is not part of the basic definition of the resource and that modifies the understanding of the element that contains it and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions. Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).
Cardinality0...*
TypeExtension
ModifierTrue
Aliasextensions, user content
Requirements

Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.

DefinitionIdentifiers associated with this Medication Administration that are defined by business processes and/or used to refer to it when a direct URL reference to the resource itself is not appropriate. They are business identifiers assigned to this resource by the performer or other systems and remain constant as the resource is updated and propagates from server to server.

TypeAnnotation
Comments

For systems that do not have structured annotations, they can simply communicate a single annotation with no author or time. This element may need to be included in narrative because of the potential for modifying information. Annotations SHOULD NOT be used to communicate "modifying" information that could be computable. (This is a SHOULD because enforcing user behavior is nearly impossible).

Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.

Aliasextensions, user content, modifiers
Requirements

Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.

Not all terminology uses fit this general pattern. In some cases, models should not use CodeableConcept and use Coding directly and provide their own structure for managing text, codings, translations and the relationship between elements and pre- and post-coordination.

MedicationAdministration.dosage.method
DefinitionA 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.
Cardinality0...1
TypeCodeableConcept
Binding

A coded concept describing the technique by which the medicine is administered.

UKCoreMedicationDosageMethod (preferred)
Comments

One of the reasons this attribute is not used often, is that the method is often pre-coordinated with the route and/or form of administration. This means the codes used in route or form may pre-coordinate the method in the route code or the form code. The implementation decision about what coding system to use for route or form code will determine how frequently the method code will be populated e.g. if route or form code pre-coordinate method code, then this attribute will not be populated often; if there is no pre-coordination then method code may be used frequently.

Cardinality0...1
TypeRatio
Comments

If the rate changes over time, and you want to capture this in MedicationAdministration, then each change should be captured as a distinct MedicationAdministration, with a specific MedicationAdministration.dosage.rate, and the date time when the rate change occurred. Typically, the MedicationAdministration.dosage.rate element is not used to convey an average rate.

Examples

Timoptol Eye Drops - An example to illustrate a medication administration of eye drops.
Example UKCore-MedicationAdministration-TimoptolEyeDrops

Example Usage Scenarios

The following are example usage scenarios for the UK Core Medication Administration profile:

  • To share inpatient or outpatient non-immunization administrations of medication between clinical systems. Example scenarios include inpatient patient transfer from ward-to-ward or hospital-to-hospital, where different clinical systems are in use. For immunisations use the Profile UKCore-Immunization resource.
  • To share patient self-administration of medication.
  • To share home-health reporting from medicines administration and monitoring devices.

Profile Specific Implementation Guidance:

Mandatory and Must Support Data Elements

The following elements are identified as MustSupport, and it is expected that consumers and suppliers SHALL support these as per the MustSupport Guidance.

ElementReason
MedicationAdministration.identifierAllows the resource to be referenced within / by other resources.
MedicationAdministration.statusAllows an administration to be marked as in-progress or completed.
MedicationAdministration.medication[x]Identifies the medication that was administered.
MedicationAdministration.subjectIdentifies the patient receiving the medication.
MedicationAdministration.effective[x]The start and end time of the administration.
MedicationAdministration.dosageThe dosage instruction for the administered medication.


Bindings (differential)

partOf

An optional reference to a Procedure that could be used for medications given intraoperatively (during an operation / procedure) where there may not be a MedicationRequest resource to reference. A reverse reference could be added as ‘partOf’ of the Procedure resource.

This element can also reference another MedicationAdministration resource. Where several medication administrations relate to the same MedicationRequest, the reference to the MedicationRequest within ‘request’ is sufficient for logical data linkage purposes. It may give additional business benefit to also logically link the MedicationAdministration resources using ‘partOf’.

Where possible, it is expected that the resource being referenced SHOULD conform to one of the following UK Core profiles:


status

The MedicationAdministration.status element SHALL be populated with a value from the International FHIR ValueSet medication-admin-status, which is shown expanded here with additional guidance.

Systems consuming the data SHOULD use MedicationAdministration.status to support workflow.

The status can be used to determine the overall status of medication administration events.

It is recommended that the MedicationAdministration.status is used to indicate the status at a high-level so that integrated systems can determine how to represent this information.

Status FHIR Definition Implementation Guidance
in-progress The administration has started but has not yet completed. Would be a suitable status to use, for example, by an infusion pump device which is interoperable with the clinical system to denote an infusion is in progress.
not-done The administration was terminated prior to any impact on the subject (though preparatory actions may have been taken) Use this when there is not the intention to undertake the administration at a future time.
on-hold Actions implied by the administration have been temporarily halted, but are expected to continue later. May also be called 'suspended'. Use this when there is the intention to administer the medication at a future time. For example, if the patient is temporarily unavailable.
completed All actions that are implied by the administration have occurred. This would be a suitable trigger to share the medication administration event with shared records.
entered-in-error The administration was entered in error and therefore nullified. There is limited value in sharing records that are entered in error.
stopped Actions implied by the administration have been permanently halted, before all of them occurred. A MedicationAdministration.statusReason SHOULD be populated with a coded reason for stopping the medication administration.

This is for things like patches and continuous infusions etc. where administration is over a period of time. The MedicationAdministration.dosage SHOULD reflect the amount administered (or whatever the source system has recorded).
unknown The authoring system does not know which of the status values currently applies for this request. Note: This concept is not to be used for 'other' - one of the statuses listed is presumed to apply, it's just not known which one. The patient may have had some encounter with this medication, but the current status is unknown. Avoid the use of this status value where possible.

statusReason

A coded reason for why an administration was not performed.

SHOULD only be populated when the MedicationAdministration.status is either stopped, not-done or on-hold.

Example scenarios for the use of status and statusReason.

Some medication was taken, but not all that was intended, for whatever reason, e.g. an infusion that was started, and finished prematurely.

  • status = stopped
  • status reason = 416093006 | Allergic reaction to drug
  • dosage = Should reflect how much was actually administered, e.g. 150ml (instead of 200ml requested)

Note: For this example it would be expected that the originating MedicationRequest would be updated with a status of stopped which should prevent the system from scheduling an administration or delete any that have been scheduled. Where administration records are retained, use the status of stopped.

Patient refused to take the medication.

  • status = not-done
  • statusReason = 182895007 | Drug declined by patient (finding) - or a child concept of the above

Where required use MedicationAdministration.note to capture additional notes for why the patient refused the medication.

Patient not available, e.g. on home leave for a couple of days, moved ward, location unknown, etc. and not recorded as on-hold.

  • status = not-done
  • statusReason = 398090008 | Patient unavailable (finding)

Medication was taken but patient then vomited all/some of the medication.

  • status = on-hold or stopped
  • statusReason = 419219000 | Drug-induced nausea and vomiting

Use MedicationAdministration.note for additional notes for what happened, provided the administration record can be amended after the vomiting episode.

An infusion for the patient is paused for a period based on blood test results. Or, a nutrition feed is paused for clinical reasons, to restart again later.

  • status = on-hold
  • statusReason = Optional. Any valid SNOMED term.
  • dosage = The dosage would either be recorded with a zero rateRatio or rateQuantity or may be fully omitted. Both must be interpreted as a zero medication administration.

medication[x]

Medication WITH dm+d code

Where a dm+d code exists it SHALL be used either as MedicationAdministration.medicationCodeableConcept.coding or as MedicationAdministration.medicationReference.Medication.code.

Where CodeableConcept is used, MedicationAdministration.medicationCodeableConcept.coding is the dm+d code and MedicationAdministration.medicationCodeableConcept.text is dm+d concept name/description.

Can be either a dm+d code as a CodeableConcept or reference to a Profile UKCore-Medication.

Using a CodeableConcept is preferred unless additional data is required that would be contained within a Profile UKCore-Medication.

The elements MedicationAdministration.medicationCodeableConcept.coding and MedicationAdministration.medicationReference.Medication.code are both bound to ValueSet UKCore-MedicationCode

Examples where a reference to a Profile UKCore-Medication would be applicable include:

  • Record a VTM with a specific form
  • Record manufacturer with a concept as described in ValueSet UKCore-MedicationCode
  • Record batch number
  • Record ingredients (for example with a magisterial prescription or an excipient).

Medication WITHOUT dm+d code

Medication not published within the dm+d may be requested in the Acute care setting.

In this scenario it is recommended to use the CodeableConcept variant for this element.

If the prescribing system has both a locally assigned code and description for the medication then;

  • The MedicationAdministration.medicationCodeableConcept.text SHOULD be the description for the medication.
  • The MedicationAdministration.medicationCodeableConcept.coding.code SHOULD be the code for the medication.
  • The MedicationAdministration.medicationCodeableConcept.coding.display SHOULD be the description for the medication, i.e. the same value as MedicationAdministration.medicationCodeableConcept.text.

If the prescribing system only has a description for the medication then;

  • The MedicationAdministration.medicationCodeableConcept.text SHOULD be the locally assigned description for the medication.

subject

A reference to the patient.

Within a FHIR Messaging or FHIR Document implementation, include a Profile UKCore-Patient resource within the Bundle with at least the minimum dataset populated as defined within the UK Core standard. The MedicationAdministration.subject.reference points to the resource in the Bundle.


context

Where possible, it is expected that the resource being referenced SHOULD conform to one of the following UK Core profiles:


supportingInformation

Where a UK Core profile exists, the resource being referenced SHOULD conform to the profile.


reasonReference

Where possible, it is expected that the resource being referenced SHOULD conform to one of the following UK Core profiles:


request

In many cases, a Profile UKCore-MedicationRequest resource will exist and can be referenced. Consideration must be made when sharing the records to either also share the MedicationRequest or make it accessible by query, if/when required.

Cases where a MedicationRequest may not exist include administration of medication bought over the counter or via an emergency supply of medication.


device

The resource being referenced SHALL conform to the UKCore-Device.


dosage

Consider aligning to the Implementation Guide for Digital Medicines, but as a minimum, MedicationAdministration.dosage.text.

A MedicationAdministration resource may be used to describe a period of no administration. The MedicationAdministration.status would be on-hold and either the dosage would be omitted, or a dosage would be recorded with a zero rate or quantity. For example;

Example of MedicationAdministration.dosage usage:
