StructureDefinition: CareConnect-MedicationRequest-1 - Detailed Descriptions

Definitions for the CareConnect-MedicationRequest-1 Profile.

1. MedicationRequest
Definition

An order or request for both supply of the medication and the instructions for administration of the medication to a patient. The resource is called "MedicationRequest" rather than "MedicationPrescription" or "MedicationOrder" to generalize the use across inpatient and outpatient settings, including care plans, etc., and to harmonize with workflow patterns.

Control0..*
Alternate NamesPrescription, Order
InvariantsDefined on this element
dom-1: If the resource is contained in another resource, it SHALL NOT contain any narrative (: contained.text.empty())
dom-2: If the resource is contained in another resource, it SHALL NOT contain nested Resources (: contained.contained.empty())
dom-3: If the resource is contained in another resource, it SHALL be referred to from elsewhere in the resource (: contained.where(('#'+id in %resource.descendants().reference).not()).empty())
dom-4: If a resource is contained in another resource, it SHALL NOT have a meta.versionId or a meta.lastUpdated (: contained.meta.versionId.empty() and contained.meta.lastUpdated.empty())
2. MedicationRequest.id
Definition

The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes.

Control0..1
Typeid
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.

3. MedicationRequest.meta
Definition

The metadata about the resource. This is content that is maintained by the infrastructure. Changes to the content may not always be associated with version changes to the resource.

Control0..1
TypeMeta
4. MedicationRequest.implicitRules
Definition

A reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content.

Control0..1
Typeuri
Is Modifiertrue
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.

This element is labelled as a modifier because the implicit rules may provide additional knowledge about the resource that modifies it's meaning or interpretation.

5. MedicationRequest.language
Definition

The base language in which the resource is written.

Control0..1
BindingA human language.
The codes SHALL be taken from Common Languages; other codes may be used where these codes are not suitable
Max Binding: All Languages
Typecode
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).

6. MedicationRequest.text
Definition

A human-readable narrative that contains a summary of the resource, and may 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.

Control0..1 This element is affected by the following invariants: dom-1
TypeNarrative
Alternate Namesnarrative, 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 in formation is added later.

7. MedicationRequest.contained
Definition

These 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.

Control0..*
TypeResource
Alternate Namesinline 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.

8. MedicationRequest.extension
Definition

An Extension

Control0..*
TypeExtension
SlicingThis element introduces a set of slices on MedicationRequest.extension. The slices are unordered and Open, and can be differentiated using the following discriminators:
  • value @ url
9. MedicationRequest.extension:repeatInformation
SliceNamerepeatInformation
Definition

Medication repeat information.

Control0..1 This element is affected by the following invariants: ele-1
TypeExtension(Extension-CareConnect-MedicationRepeatInformation-1) (Extension Type: Choice of: base64Binary, boolean, code, date, dateTime, decimal, id, instant, integer, markdown, oid, positiveInt, string, time, unsignedInt, uri, Address, Age, Annotation, Attachment, CodeableConcept, Coding, ContactPoint, Count, Distance, Duration, HumanName, Identifier, Money, Period, Quantity, Range, Ratio, Reference, SampledData, Signature, Timing, Meta)

ele-1: All FHIR elements must have a @value or children (: hasValue() | (children().count() > id.count()))
ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists())
10. MedicationRequest.extension:statusReason
SliceNamestatusReason
Definition

To record the reason the medication (plan or order) was stopped and the date this occurred.

Control0..1 This element is affected by the following invariants: ele-1
TypeExtension(Extension-CareConnect-MedicationStatusReason-1) (Extension Type: Choice of: base64Binary, boolean, code, date, dateTime, decimal, id, instant, integer, markdown, oid, positiveInt, string, time, unsignedInt, uri, Address, Age, Annotation, Attachment, CodeableConcept, Coding, ContactPoint, Count, Distance, Duration, HumanName, Identifier, Money, Period, Quantity, Range, Ratio, Reference, SampledData, Signature, Timing, Meta)

11. MedicationRequest.extension:prescriptionType
SliceNameprescriptionType
Definition

Control0..1 This element is affected by the following invariants: ele-1
TypeExtension(Extension-CareConnect-PrescriptionType-1) (Extension Type: CodeableConcept)
InvariantsDefined on this element
ele-1: All FHIR elements must have a @value or children (: hasValue() | (children().count() > id.count()))
ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists())
12. MedicationRequest.modifierExtension
Definition

May 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. Usually modifier elements provide negation or qualification. In order 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.

Control0..*
TypeExtension
Is Modifiertrue
Alternate Namesextensions, 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.

13. MedicationRequest.identifier
Definition

This records identifiers associated with this medication request 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. For example a re-imbursement system might issue its own id for each prescription that is created. This is particularly important where FHIR only provides part of an entire workflow process where records must be tracked through an entire system.

NoteThis is a business identifier, not a resource identifier (see discussion)
Control0..*
TypeIdentifier
14. MedicationRequest.identifier.id
Definition

unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

SlicingThis element introduces a set of slices on MedicationRequest.identifier.extension. The slices are unordered and Open, and can be differentiated using the following discriminators:
  • value @ url
16. MedicationRequest.identifier.use
Definition

The purpose of this identifier.

Control0..1
BindingIdentifies the purpose for this identifier, if known .
The codes SHALL be taken from IdentifierUse
Typecode
Is Modifiertrue
Requirements

Allows the appropriate identifier for a particular context of use to be selected from among a set of identifiers.

Comments

This is labeled as "Is Modifier" because applications should not mistake a temporary id for a permanent one. Applications can assume that an identifier is permanent unless it explicitly says that it is temporary.

17. MedicationRequest.identifier.type
Definition

A coded type for the identifier that can be used to determine which identifier to use for a specific purpose.

Control0..1
BindingA coded type for an identifier that can be used to determine which identifier to use for a specific purpose.
The codes SHALL be taken from Identifier Type Codes; other codes may be used where these codes are not suitable
TypeCodeableConcept
Requirements

Allows users to make use of identifiers when the identifier system is not known.

Comments

This element deals only with general categories of identifiers. It SHOULD not be used for codes that correspond 1..1 with the Identifier.system. Some identifiers may fall into multiple categories due to common usage.

Where the system is known, a type is unnecessary because the type is always part of the system definition. However systems often need to handle identifiers where the system is not known. There is not a 1:1 relationship between type and system, since many different systems have the same type.

18. MedicationRequest.identifier.system
Definition

Establishes the namespace for the value - that is, a URL that describes a set values that are unique.

Control1..1
Typeuri
Requirements

There are many sets of identifiers. To perform matching of two identifiers, we need to know what set we're dealing with. The system identifies a particular set of unique identifiers.

Example
General:http://www.acme.com/identifiers/patient
19. MedicationRequest.identifier.value
Definition

The portion of the identifier typically relevant to the user and which is unique within the context of the system.

Control1..1
Typestring
Comments

If the value is a full URI, then the system SHALL be urn:ietf:rfc:3986. The value's primary purpose is computational mapping. As a result, it may be normalized for comparison purposes (e.g. removing non-significant whitespace, dashes, etc.) A value formatted for human display can be conveyed using the Rendered Value extension.

Example
General:123456
20. MedicationRequest.identifier.period
Definition

Time period during which identifier is/was valid for use.

Control0..1
TypePeriod
21. MedicationRequest.identifier.assigner
Definition

Organization that issued/manages the identifier.

Control0..1
TypeReference(CareConnect-Organization-1)
Comments

The Identifier.assigner may omit the .reference element and only contain a .display element reflecting the name or other textual information about the assigning organization.

22. MedicationRequest.definition
Definition

Protocol or definition followed by this request.

Control0..*
TypeReference(ActivityDefinition | PlanDefinition)
23. MedicationRequest.basedOn

24. MedicationRequest.groupIdentifier
Definition

A shared identifier common to all requests that were authorized more or less simultaneously by a single author, representing the identifier of the requisition or prescription.

Control0..1
TypeIdentifier
Requirements

Requests are linked either by a "basedOn" relationship (i.e. one request is fulfilling another) or by having a common requisition. Requests that are part of the same requisition are generally treated independently from the perspective of changing their state or maintaining them after initial creation.

25. MedicationRequest.groupIdentifier.id

Definition

Whether the request is a proposal, plan, or an original order.

Control1..1
BindingThe kind of medication order
The codes SHALL be taken from MedicationRequestIntent
Typecode
Is Modifiertrue
Comments

It is expected that the type of requester will be restricted for different stages of a MedicationRequest. For example, Proposals can be created by a patient, relatedPerson, Practitioner or Device. Plans can be created by Practitioners, Patients, RelatedPersons and Devices. Original orders can be created by a Practitioner only.

An instance-order is an instantiation of a request or order and may be used to populate Medication Administration Record.

This element is labeled as a modifier because the intent alters when and how the resource is actually applicable.

35. MedicationRequest.category

Control0..1
Typeinteger
Requirements

If the sequence number of multiple Dosages is the same, then it is implied that the instructions are to be treated as concurrent. If the sequence number is different, then the Dosages are intended to be sequential.

Requirements

Free text dosage instructions can be used for cases where the instructions are too complex to code. The content of this attribute does not include the name or description of the medication. When coded instructions are present, the free text instructions may still be present for display to humans taking or administering the medication. It is expected that the text instructions will always be populated. If the dosage.timing attribute is also populated, then the dosage.text should reflect the same information as the timing.

Control0..1

Requirements

The amount of therapeutic or other substance given at one administration event.

Comments

Note that this specifies the quantity of the specified medication, not the quantity for each active ingredient(s). Each ingredient amount can be communicated in the Medication resource. For example, if one wants to communicate that a tablet was 375 mg, where the dose was one tablet, you can use the Medication resource to document that the tablet was comprised of 375 mg of drug XYZ. Alternatively if the dose was 375 mg, then you may only need to use the Medication resource to indicate this was a tablet. If the example were an IV such as dopamine and you wanted to communicate that 400mg of dopamine was mixed in 500 ml of some IV solution, then this would all be communicated in the Medication resource. If the administration is not intended to be instantaneous (rate is present or timing has a duration), this can be specified to convey the total amount to be administered over the period of time as indicated by the schedule e.g. 500 ml in dose, with timing used to convey that this should be done over 4 hours.

Requirements

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. Sometimes, a rate can imply duration when expressed as total volume / duration (e.g. 500mL/2 hours implies a duration of 2 hours). However, when rate doesn't imply duration (e.g. 250mL/hour), then the timing.repeat.duration is needed to convey the infuse over time period.

Comments

It is possible to supply both a rate and a doseQuantity to provide full details about how the medication is to be administered and supplied. If the rate is intended to change over time, depending on local rules/regulations, each change should be captured as a new version of the MedicationRequest with an updated rate, or captured with a new MedicationRequest with the new rate.

101. MedicationRequest.dispenseRequest

Until then, it can be queried directly as the Provenance that points to this version using _revinclude All Provenances should have some historical version of this Request as their subject.).
