MedicationStatementPSON (MedicationStatement) | I | MedicationStatement | Element idMedicationStatement Record of medication being taken by a patient DefinitionA record of a medication that is being consumed by a patient. A MedicationStatement may indicate that the patient may be taking the medication now or has taken the medication in the past or will be taking the medication in the future. The source of this information can be the patient, significant other (such as a family member or spouse), or a clinician. A common scenario where this information is captured is during the history taking process during a patient visit or stay. The medication information may come from sources such as the patient's memory, from a prescription bottle, or from a list of medications the patient, clinician or other party maintains. The primary difference between a medication statement and a medication administration is that the medication administration has complete administration information and is based on actual administration information from the person who administered the medication. A medication statement is often, if not always, less specific. There is no required date/time when the medication was administered, in fact we only know that a source has reported the patient is taking this medication, where details such as time, quantity, or rate or even medication product may be incomplete or missing or less precise. As stated earlier, the medication statement information may come from the patient's memory, from a prescription bottle or from a list of medications the patient, clinician or other party maintains. Medication administration is more formal and is not missing detailed information. Jurisdictions mapping prescription data into FHIR profiles for the patient summary should use the MedicationRequest resource. Use of the MedicationStatement profile should be reserved for communicating a statement about the patient's usage of the medication that is ultimately provided by a patient, significant other, or a clinican.

id | Σ | 0..1 | string | There are no (further) constraints on this element Element idMedicationStatement.id Logical id of this artifact DefinitionThe logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes. The only time that a resource does not have an id is when it is being submitted to the server using a create operation. |
meta | S Σ | 1..1 | Meta | There are no (further) constraints on this element Element idMedicationStatement.meta Metadata about the resource 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.
|
id | 0..1 | string | There are no (further) constraints on this element Element idMedicationStatement.meta.id Unique id for inter-element referencing DefinitionUnique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

extension | I | 0..* | Extension | There are no (further) constraints on this element Element idMedicationStatement.meta.extension Additional content defined by implementations Alternate namesextensions, user content DefinitionMay be used to represent additional information that is not part of the basic definition of the element. 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. 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. Unordered, Open, by url(Value) Extensions are always sliced by (at least) url Constraints
|
versionId | Σ | 0..1 | id | There are no (further) constraints on this element Element idMedicationStatement.meta.versionId Version specific identifier DefinitionThe version specific identifier, as it appears in the version portion of the URL. This value changes when the resource is created, updated, or deleted. The server assigns this value, and ignores what the client specifies, except in the case that the server is imposing version integrity on updates/deletes.
|
lastUpdated | Σ | 0..1 | instant | There are no (further) constraints on this element Element idMedicationStatement.meta.lastUpdated When the resource version last changed DefinitionWhen the resource last changed - e.g. when the version changed. This value is always populated except when the resource is first being created. The server / resource manager sets this value; what a client provides is irrelevant. This is equivalent to the HTTP Last-Modified and SHOULD have the same value on a read interaction.
|
source | Σ | 0..1 | uri | There are no (further) constraints on this element Element idMedicationStatement.meta.source Identifies where the resource comes from DefinitionA uri that identifies the source system of the resource. This provides a minimal amount of Provenance information that can be used to track or differentiate the source of information in the resource. The source may identify another FHIR server, document, message, database, etc. In the provenance resource, this corresponds to Provenance.entity.what[x]. The exact use of the source (and the implied Provenance.entity.role) is left to implementer discretion. Only one nominated source is allowed; for additional provenance details, a full Provenance resource should be used. This element can be used to indicate where the current master source of a resource that has a canonical URL if the resource is no longer hosted at the canonical URL.
|
profile | S Σ | 1..* | canonical(StructureDefinition) | There are no (further) constraints on this element Element idMedicationStatement.meta.profile Profiles this resource claims to conform to DefinitionA list of profiles (references to StructureDefinition resources) that this resource claims to conform to. The URL is a reference to StructureDefinition.url. It is up to the server and/or other infrastructure of policy to determine whether/how these claims are verified and/or updated over time. The list of profile URLs is a set. canonical(StructureDefinition) Constraints
|
security | Σ | 0..* | CodingBinding | There are no (further) constraints on this element Element idMedicationStatement.meta.security Security Labels applied to this resource DefinitionSecurity labels applied to this resource. These tags connect specific resources to the overall security policy and infrastructure. The security labels can be updated without changing the stated version of the resource. The list of security labels is a set. Uniqueness is based the system/code, and version and display are ignored. Security Labels from the Healthcare Privacy and Security Classification System.
|
tag | Σ | 0..* | Coding | There are no (further) constraints on this element Element idMedicationStatement.meta.tag Tags applied to this resource DefinitionTags applied to this resource. Tags are intended to be used to identify and relate resources to process and workflow, and applications are not required to consider the tags when interpreting the meaning of a resource. The tags can be updated without changing the stated version of the resource. The list of tags is a set. Uniqueness is based the system/code, and version and display are ignored. Codes that represent various types of tags, commonly workflow-related; e.g. "Needs review by Dr. Jones".
|
implicitRules | Σ ?! | 0..1 | uri | There are no (further) constraints on this element Element idMedicationStatement.implicitRules A set of rules under which this content was created 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. 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.
|
language | 0..1 | codeBinding | There are no (further) constraints on this element Element idMedicationStatement.language Language of the resource content DefinitionThe base language in which the resource is written. 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). A human language.
| |
text | 0..1 | Narrative | There are no (further) constraints on this element Element idMedicationStatement.text Text summary of the resource, for human interpretation Alternate namesnarrative, html, xhtml, display 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. 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.
| |
contained | 0..* | Resource | There are no (further) constraints on this element Element idMedicationStatement.contained Contained, inline Resources Alternate namesinline resources, anonymous resources, contained resources 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. 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.

extension | I | 0..* | Extension | There are no (further) constraints on this element Element idMedicationStatement.extension Additional content defined by implementations Alternate namesextensions, user content 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. 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.

RenderedDosageInstruction | I | 0..1 | Extension | Element idMedicationStatement.extension:RenderedDosageInstruction Extension for representing rendered dosage instruction. Alternate namesextensions, user content DefinitionA free form textual specification generated from the input specifications as created by the provider.This is made up of either an 'Ad-hoc instruction' or 'Textual rendition of the structured dosage lines', plus route, dosage unit, and other pertinent administration information specified by the provider. Use of structured fields for dosage instructions is heavily encouraged by this specification to promote interoperability of patient summaries. However, this extension is provided to make implementers aware that legacy medication data may come from some systems in this format. This extension is used by PrescribeIT implementations when the system has difficulty sending very complex dosage instructions in the form of structured data. Implementers are encouraged to read the PrescribeIT Specification (https://specs.prescribeit.ca/R5.0/erx/extension-ext-medication-rendered-dosage.html) to understand the context around its use. http://prescribeit.ca/fhir/StructureDefinition/ext-rendered-dosage-instruction Constraints

modifierExtension | ?! I | 0..* | Extension | There are no (further) constraints on this element Element idMedicationStatement.modifierExtension Extensions that cannot be ignored Alternate namesextensions, user content 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). 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. 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.

identifier | Σ | 0..* | Identifier | There are no (further) constraints on this element Element idMedicationStatement.identifier External identifier DefinitionIdentifiers associated with this Medication Statement 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. This is a business identifier, not a resource identifier.

basedOn | Σ I | 0..* | Reference(MedicationRequest | CarePlan | ServiceRequest) | There are no (further) constraints on this element Element idMedicationStatement.basedOn Fulfils plan, proposal or order DefinitionA plan, proposal or order that is fulfilled in whole or in part by this event. Allows tracing of authorization for the event and tracking whether proposals/recommendations were acted upon. References SHALL be a reference to an actual FHIR resource, and SHALL be resolveable (allowing for access control, temporary unavailability, etc.). Resolution can be either by retrieval from the URL, or, where applicable by resource type, by treating an absolute reference as a canonical URL and looking it up in a local registry/repository. Reference(MedicationRequest | CarePlan | ServiceRequest) Constraints
|
partOf | Σ I | 0..* | Reference(MedicationAdministration | MedicationDispense | MedicationStatement | Procedure | Observation) | There are no (further) constraints on this element Element idMedicationStatement.partOf Part of referenced event DefinitionA larger event of which this particular event is a component or step. This should not be used when indicating which resource a MedicationStatement has been derived from. If that is the use case, then MedicationStatement.derivedFrom should be used. References SHALL be a reference to an actual FHIR resource, and SHALL be resolveable (allowing for access control, temporary unavailability, etc.). Resolution can be either by retrieval from the URL, or, where applicable by resource type, by treating an absolute reference as a canonical URL and looking it up in a local registry/repository.

|
status | S Σ ?! | 1..1 | codeBinding | Element idMedicationStatement.status active | completed | entered-in-error | intended | stopped | on-hold | unknown | not-taken DefinitionA code representing the patient or other source's judgment about the state of the medication used that this statement is about. Generally, this will be active or completed. In the scope of the IPS the entered-in-error concept is not allowed. Implementors should be aware that the shift to R5 MedicationUsage will also involve a new value set for status that is constrained to: recorded, entered-in-error, and draft. A coded concept indicating the current status of a MedicationStatement.
|
statusReason | 0..* | CodeableConcept | There are no (further) constraints on this element Element idMedicationStatement.statusReason Reason for current status DefinitionCaptures the reason for the current state of the MedicationStatement. This is generally only used for "exception" statuses such as "not-taken", "on-hold", "cancelled" or "entered-in-error". The reason for performing the event at all is captured in reasonCode, not here. A coded concept indicating the reason for the status of the statement.
| |
category | Σ | 0..1 | CodeableConceptBinding | There are no (further) constraints on this element Element idMedicationStatement.category Type of medication usage DefinitionIndicates where the medication is expected to be consumed or administered. 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. A coded concept identifying where the medication included in the MedicationStatement is expected to be consumed or administered.
|
medication[x] | S Σ | 1..1 | Element idMedicationStatement.medication[x] What medication was taken DefinitionIdentifies the medication being administered or the reason for absent or unknown Medication. This is either a link to a resource representing the details of the medication or a simple attribute carrying a code. To improve global interoperability is strongly encouraged that the reference to a medication resource is used, limiting the usage of the medicationCodeableConcept only to the cases in which no other information than a simple code is available. Work is underway to define the pan-Canadian terminology that will be preferred and/or socialized for this element. Unordered, Closed, by $this(Type) BindingA coded concept identifying the substance or product being taken.
| |
medicationReference | S Σ | 0..1 | Reference(MedicationPSON) | Element idMedicationStatement.medication[x]:medicationReference What medication was taken DefinitionIdentifies the medication being administered or the reason for absent or unknown Medication. This is either a link to a resource representing the details of the medication or a simple attribute carrying a code. To improve global interoperability is strongly encouraged that the reference to a medication resource is used, limiting the usage of the medicationCodeableConcept only to the cases in which no other information than a simple code is available. IPS-UV Note: If only a code is specified, then it needs to be a code for a specific product. If more information is required, then the use of the medication resource is recommended. For example, if you require form or lot number, then you must reference the Medication resource.
|
medicationCodeableConcept | S Σ | 0..1 | CodeableConceptPSONBinding | Element idMedicationStatement.medication[x]:medicationCodeableConcept Code for absent or unknown medication - or for supplying a codeableConcept when no information other than a simple code is available DefinitionCode for a negated/excluded medication statement. This describes a categorical negated statement (e.g., "No known medications") Because the IPS-UV value set on this slice is extensible, it can be used to supply other medication codes when only a simple code is available. For all CodeableConcepts, at least one of coding or text must be present. If coding contains only a display value (no code) then CodeableConcept must include text. Representation of unknown or absent medications
|
subject | S Σ I | 1..1 | Reference(PatientPSON) | Element idMedicationStatement.subject Who is/was taking the medication DefinitionThe person, animal or group who is/was taking the medication. References SHALL be a reference to an actual FHIR resource, and SHALL be resolveable (allowing for access control, temporary unavailability, etc.). Resolution can be either by retrieval from the URL, or, where applicable by resource type, by treating an absolute reference as a canonical URL and looking it up in a local registry/repository.

reference | S Σ I | 1..1 | string | There are no (further) constraints on this element Element idMedicationStatement.subject.reference Literal reference, Relative, internal or absolute URL DefinitionA reference to a location at which the other resource is found. The reference may be a relative reference, in which case it is relative to the service base URL, or an absolute URL that resolves to the location where the resource is found. The reference may be version specific or not. If the reference is not to a FHIR RESTful server, then it should be assumed to be version specific. Internal fragment references (start with '#') refer to contained resources. Using absolute URLs provides a stable scalable approach suitable for a cloud/web context, while using relative/logical references provides a flexible approach suitable for use when trading across closed eco-system boundaries. Absolute URLs do not need to point to a FHIR RESTful server, though this is the preferred approach. If the URL conforms to the structure "/[type]/[id]" then it should be assumed that the reference is to a FHIR RESTful server.
|
type | Σ | 0..1 | uriBinding | There are no (further) constraints on this element Element idMedicationStatement.subject.type Type the reference refers to (e.g. "Patient") DefinitionThe expected type of the target of the reference. If both Reference.type and Reference.reference are populated and Reference.reference is a FHIR URL, both SHALL be consistent. The type is the Canonical URL of Resource Definition that is the type this reference refers to. References are URLs that are relative to http://hl7.org/fhir/StructureDefinition/ e.g. "Patient" is a reference to http://hl7.org/fhir/StructureDefinition/Patient. Absolute URLs are only allowed for logical models (and can only be used in references in logical models, not resources). This element is used to indicate the type of the target of the reference. This may be used which ever of the other elements are populated (or not). In some cases, the type of the target may be determined by inspection of the reference (e.g. a RESTful URL) or by resolving the target of the reference; if both the type and a reference is provided, the reference SHALL resolve to a resource of the same type as that specified. Aa resource (or, for logical models, the URI of the logical model).
|
identifier | Σ | 0..1 | Identifier | There are no (further) constraints on this element Element idMedicationStatement.subject.identifier Logical reference, when literal reference is not known DefinitionAn identifier for the target resource. This is used when there is no way to reference the other resource directly, either because the entity it represents is not available through a FHIR server, or because there is no way for the author of the resource to convert a known identifier to an actual location. There is no requirement that a Reference.identifier point to something that is actually exposed as a FHIR instance, but it SHALL point to a business concept that would be expected to be exposed as a FHIR instance, and that instance would need to be of a FHIR resource type allowed by the reference. When an identifier is provided in place of a reference, any system processing the reference will only be able to resolve the identifier to a reference if it understands the business context in which the identifier is used. Sometimes this is global (e.g. a national identifier) but often it is not. For this reason, none of the useful mechanisms described for working with references (e.g. chaining, includes) are possible, nor should servers be expected to be able resolve the reference. Servers may accept an identifier based reference untouched, resolve it, and/or reject it - see CapabilityStatement.rest.resource.referencePolicy. When both an identifier and a literal reference are provided, the literal reference is preferred. Applications processing the resource are allowed - but not required - to check that the identifier matches the literal reference Applications converting a logical reference to a literal reference may choose to leave the logical reference present, or remove it. Reference is intended to point to a structure that can potentially be expressed as a FHIR resource, though there is no need for it to exist as an actual FHIR resource instance - except in as much as an application wishes to actual find the target of the reference. The content referred to be the identifier must meet the logical constraints implied by any limitations on what resource types are permitted for the reference. For example, it would not be legitimate to send the identifier for a drug prescription if the type were Reference(Observation|DiagnosticReport). One of the use-cases for Reference.identifier is the situation where no FHIR representation exists (where the type is Reference (Any).
|
display | Σ | 0..1 | string | There are no (further) constraints on this element Element idMedicationStatement.subject.display Text alternative for the resource DefinitionPlain text narrative that identifies the resource in addition to the resource reference. This is generally not the same as the Resource.text of the referenced resource. The purpose is to identify what's being referenced, not to fully describe it.
|
context | Σ I | 0..1 | Reference(Encounter | EpisodeOfCare) | There are no (further) constraints on this element Element idMedicationStatement.context Encounter / Episode associated with MedicationStatement DefinitionThe encounter or episode of care that establishes the context for this MedicationStatement. References SHALL be a reference to an actual FHIR resource, and SHALL be resolveable (allowing for access control, temporary unavailability, etc.). Resolution can be either by retrieval from the URL, or, where applicable by resource type, by treating an absolute reference as a canonical URL and looking it up in a local registry/repository. Reference(Encounter | EpisodeOfCare) Constraints
|
effective[x] | S Σ | 1..1 | There are no (further) constraints on this element Element idMedicationStatement.effective[x] The date/time or interval when the medication is/was/will be taken DefinitionThe interval of time during which it is being asserted that the patient is/was/will be taking the medication (or was not taking, when the MedicationStatement.taken element is No). This attribute reflects the period over which the patient consumed the medication and is expected to be populated on the majority of Medication Statements. If the medication is still being taken at the time the statement is recorded, the "end" date will be omitted. The date/time attribute supports a variety of dates - year, year/month and exact date. If something more than this is required, this should be conveyed as text.

Note: Use derivedFrom when a MedicationStatement is derived from other resources, e.g. Claim or MedicationRequest. References SHALL be a reference to an actual FHIR resource, and SHALL be resolveable (allowing for access control, temporary unavailability, etc.).

Likely references would be to MedicationRequest, MedicationDispense, Claim, Observation or QuestionnaireAnswers. The most common use cases for deriving a MedicationStatement comes from creating a MedicationStatement from a MedicationRequest or from a lab observation or a claim. it should be noted that the amount of information that is available varies from the type resource that you derive the MedicationStatement from.

note | 0..* | Annotation | There are no (further) constraints on this element Element idMedicationStatement.note Further information about the statement DefinitionProvides extra information about the medication statement that is not conveyed by the other attributes. 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).

dosage | S | 0..* | Dosage | There are no (further) constraints on this element Element idMedicationStatement.dosage Details of how medication is/was taken or should be taken DefinitionIndicates how the medication is/was or should be taken by the patient. The dates included in the dosage on a Medication Statement reflect the dates for a given dose. For example, "from November 1, 2016 to November 3, 2016, take one tablet daily and from November 4, 2016 to November 7, 2016, take two tablets daily." It is expected that this specificity may only be populated where the patient brings in their labeled container or where the Medication Statement is derived from a MedicationRequest.

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 can 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). 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. 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.

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. Additional information about administration or preparation of the medication should be included as text. Note that FHIR strings SHALL NOT exceed 1MB in size

additionalInstruction | Σ | 0..* | CodeableConcept | There are no (further) constraints on this element Element idMedicationStatement.dosage.additionalInstruction Supplemental instruction or warnings to the patient - e.g. "with meals", "may cause drowsiness" DefinitionSupplemental instructions to the patient on how to take the medication (e.g. "with meals" or"take half to one hour before food") or warnings for the patient about the medication (e.g. "may cause drowsiness" or "avoid exposure of skin to direct sunlight or sunlamps"). Additional instruction is intended to be coded, but where no code exists, the element could include text. For example, "Swallow with plenty of water" which might or might not be coded. Information about administration or preparation of the medication (e.g. "infuse as rapidly as possibly via intraperitoneal port" or "immediately following drug x") should be populated in dosage.text. A coded concept identifying additional instructions such as "take with water" or "avoid operating heavy machinery".

timing | S Σ | 0..1 | Timing | There are no (further) constraints on this element Element idMedicationStatement.dosage.timing When medication should be administered DefinitionWhen medication should be administered. The timing schedule for giving the medication to the patient. This data type allows many different expressions. For example: "Every 8 hours"; "Three times a day"; "1/2 an hour before breakfast for 10 days from 23-Dec 2011:"; "15 Oct 2013, 17 Oct 2013 and 1 Nov 2013". 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. This attribute might not always be populated while the Dosage.text is expected to be populated. If both are populated, then the Dosage.text should reflect the content of the Dosage.timing.

asNeeded[x] | Σ | 0..1 | There are no (further) constraints on this element Element idMedicationStatement.dosage.asNeeded[x] Take "as needed" (for x) DefinitionIndicates whether the Medication is only taken when needed within a specific dosing schedule (Boolean option), or it indicates the precondition for taking the Medication (CodeableConcept). Can express "as needed" without a reason by setting the Boolean = True. In this case the CodeableConcept is not populated. Or you can express "as needed" with a reason by including the CodeableConcept. In this case the Boolean is assumed to be True. If you set the Boolean to False, then the dose is given according to the schedule and is not "prn" or "as needed". A coded concept identifying the precondition that should be met or evaluated prior to consuming or administering a medication dose. For example "pain", "30 minutes prior to sexual intercourse", "on flare-up" etc.

dose[x] | Σ | 0..1 | There are no (further) constraints on this element Element idMedicationStatement.dosage.doseAndRate.dose[x] Amount of medication per dose DefinitionAmount of medication per dose. The amount of therapeutic or other substance given at one administration event. 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.

rate[x] | Σ | 0..1 | There are no (further) constraints on this element Element idMedicationStatement.dosage.doseAndRate.rate[x] Amount of medication per unit of time DefinitionAmount of medication per unit of time. 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. 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. It is possible to specify a rate over time (for example, 100 ml/hour) using either the rateRatio and rateQuantity. The rateQuantity approach requires systems to have the capability to parse UCUM grammer where ml/hour is included rather than a specific ratio where the time is specified as the denominator. Where a rate such as 500ml over 2 hours is specified, the use of rateRatio may be more semantically correct than specifying using a rateQuantity of 250 mg/hour.

The maximum total quantity of a therapeutic substance that may be administered to a subject per administration. This is intended for use as an adjunct to the dosage when there is an upper cap. For example, a body surface area related dose with a maximum amount, such as 1.5 mg/m2 (maximum 2 mg) IV over 5 – 10 minutes would have doseQuantity of 1.5 mg/m2 and maxDosePerAdministration of 2 mg.

Hybrid View
MedicationStatementPSON (MedicationStatement) | I | MedicationStatement | Element idMedicationStatement Record of medication being taken by a patient DefinitionA record of a medication that is being consumed by a patient. A MedicationStatement may indicate that the patient may be taking the medication now or has taken the medication in the past or will be taking the medication in the future. The source of this information can be the patient, significant other (such as a family member or spouse), or a clinician. A common scenario where this information is captured is during the history taking process during a patient visit or stay. The medication information may come from sources such as the patient's memory, from a prescription bottle, or from a list of medications the patient, clinician or other party maintains. The primary difference between a medication statement and a medication administration is that the medication administration has complete administration information and is based on actual administration information from the person who administered the medication. A medication statement is often, if not always, less specific. There is no required date/time when the medication was administered, in fact we only know that a source has reported the patient is taking this medication, where details such as time, quantity, or rate or even medication product may be incomplete or missing or less precise. As stated earlier, the medication statement information may come from the patient's memory, from a prescription bottle or from a list of medications the patient, clinician or other party maintains. Medication administration is more formal and is not missing detailed information. Jurisdictions mapping prescription data into FHIR profiles for the patient summary should use the MedicationRequest resource. Use of the MedicationStatement profile should be reserved for communicating a statement about the patient's usage of the medication that is ultimately provided by a patient, significant other, or a clinican.

This provides a minimal amount of Provenance information that can be used to track or differentiate the source of information in the resource. The source may identify another FHIR server, document, message, database, etc. In the provenance resource, this corresponds to Provenance.entity.what[x]. The exact use of the source (and the implied Provenance.entity.role) is left to implementer discretion. Only one nominated source is allowed; for additional provenance details, a full Provenance resource should be used. This element can be used to indicate where the current master source of a resource that has a canonical URL if the resource is no longer hosted at the canonical URL.

Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc. 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.

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).

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. 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.

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.

RenderedDosageInstruction | I | 0..1 | Extension | Element idMedicationStatement.extension:RenderedDosageInstruction Extension for representing rendered dosage instruction. Alternate namesextensions, user content DefinitionA free form textual specification generated from the input specifications as created by the provider.This is made up of either an 'Ad-hoc instruction' or 'Textual rendition of the structured dosage lines', plus route, dosage unit, and other pertinent administration information specified by the provider. Use of structured fields for dosage instructions is heavily encouraged by this specification to promote interoperability of patient summaries. However, this extension is provided to make implementers aware that legacy medication data may come from some systems in this format. This extension is used by PrescribeIT implementations when the system has difficulty sending very complex dosage instructions in the form of structured data. Implementers are encouraged to read the PrescribeIT Specification (https://specs.prescribeit.ca/R5.0/erx/extension-ext-medication-rendered-dosage.html) to understand the context around its use. http://prescribeit.ca/fhir/StructureDefinition/ext-rendered-dosage-instruction Constraints

category | Σ | 0..1 | CodeableConceptBinding | There are no (further) constraints on this element Element idMedicationStatement.category Type of medication usage DefinitionIndicates where the medication is expected to be consumed or administered. 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. A coded concept identifying where the medication included in the MedicationStatement is expected to be consumed or administered.

medication[x] | S Σ | 1..1 | Element idMedicationStatement.medication[x] What medication was taken DefinitionIdentifies the medication being administered or the reason for absent or unknown Medication. This is either a link to a resource representing the details of the medication or a simple attribute carrying a code. To improve global interoperability is strongly encouraged that the reference to a medication resource is used, limiting the usage of the medicationCodeableConcept only to the cases in which no other information than a simple code is available. Work is underway to define the pan-Canadian terminology that will be preferred and/or socialized for this element.

reference | S Σ I | 1..1 | string | There are no (further) constraints on this element Element idMedicationStatement.subject.reference Literal reference, Relative, internal or absolute URL DefinitionA reference to a location at which the other resource is found. The reference may be a relative reference, in which case it is relative to the service base URL, or an absolute URL that resolves to the location where the resource is found. The reference may be version specific or not. If the reference is not to a FHIR RESTful server, then it should be assumed to be version specific. Internal fragment references (start with '#') refer to contained resources. Using absolute URLs provides a stable scalable approach suitable for a cloud/web context, while using relative/logical references provides a flexible approach suitable for use when trading across closed eco-system boundaries. Absolute URLs do not need to point to a FHIR RESTful server, though this is the preferred approach. If the URL conforms to the structure "/[type]/[id]" then it should be assumed that the reference is to a FHIR RESTful server.
|
type | Σ | 0..1 | uriBinding | There are no (further) constraints on this element Element idMedicationStatement.subject.type Type the reference refers to (e.g. "Patient") DefinitionThe expected type of the target of the reference. If both Reference.type and Reference.reference are populated and Reference.reference is a FHIR URL, both SHALL be consistent. The type is the Canonical URL of Resource Definition that is the type this reference refers to. References are URLs that are relative to http://hl7.org/fhir/StructureDefinition/ e.g. "Patient" is a reference to http://hl7.org/fhir/StructureDefinition/Patient. Absolute URLs are only allowed for logical models (and can only be used in references in logical models, not resources). This element is used to indicate the type of the target of the reference. This may be used which ever of the other elements are populated (or not). In some cases, the type of the target may be determined by inspection of the reference (e.g. a RESTful URL) or by resolving the target of the reference; if both the type and a reference is provided, the reference SHALL resolve to a resource of the same type as that specified. Aa resource (or, for logical models, the URI of the logical model).
|
identifier | Σ | 0..1 | Identifier | There are no (further) constraints on this element Element idMedicationStatement.subject.identifier Logical reference, when literal reference is not known DefinitionAn identifier for the target resource. This is used when there is no way to reference the other resource directly, either because the entity it represents is not available through a FHIR server, or because there is no way for the author of the resource to convert a known identifier to an actual location. There is no requirement that a Reference.identifier point to something that is actually exposed as a FHIR instance, but it SHALL point to a business concept that would be expected to be exposed as a FHIR instance, and that instance would need to be of a FHIR resource type allowed by the reference. When an identifier is provided in place of a reference, any system processing the reference will only be able to resolve the identifier to a reference if it understands the business context in which the identifier is used. Sometimes this is global (e.g. a national identifier) but often it is not. For this reason, none of the useful mechanisms described for working with references (e.g. chaining, includes) are possible, nor should servers be expected to be able resolve the reference. Servers may accept an identifier based reference untouched, resolve it, and/or reject it - see CapabilityStatement.rest.resource.referencePolicy. When both an identifier and a literal reference are provided, the literal reference is preferred. Applications processing the resource are allowed - but not required - to check that the identifier matches the literal reference Applications converting a logical reference to a literal reference may choose to leave the logical reference present, or remove it. Reference is intended to point to a structure that can potentially be expressed as a FHIR resource, though there is no need for it to exist as an actual FHIR resource instance - except in as much as an application wishes to actual find the target of the reference. The content referred to be the identifier must meet the logical constraints implied by any limitations on what resource types are permitted for the reference. For example, it would not be legitimate to send the identifier for a drug prescription if the type were Reference(Observation|DiagnosticReport). One of the use-cases for Reference.identifier is the situation where no FHIR representation exists (where the type is Reference (Any).

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 can 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). 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.

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. This attribute might not always be populated while the Dosage.text is expected to be populated. If both are populated, then the Dosage.text should reflect the content of the Dosage.timing.

dose[x] | Σ | 0..1 | There are no (further) constraints on this element Element idMedicationStatement.dosage.doseAndRate.dose[x] Amount of medication per dose DefinitionAmount of medication per dose. The amount of therapeutic or other substance given at one administration event. 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.

rate[x] | Σ | 0..1 | There are no (further) constraints on this element Element idMedicationStatement.dosage.doseAndRate.rate[x] Amount of medication per unit of time DefinitionAmount of medication per unit of time. 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. 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. It is possible to specify a rate over time (for example, 100 ml/hour) using either the rateRatio and rateQuantity. The rateQuantity approach requires systems to have the capability to parse UCUM grammer where ml/hour is included rather than a specific ratio where the time is specified as the denominator. Where a rate such as 500ml over 2 hours is specified, the use of rateRatio may be more semantically correct than specifying using a rateQuantity of 250 mg/hour.

maxDosePerAdministration | Σ I | 0..1 | SimpleQuantity | There are no (further) constraints on this element Element idMedicationStatement.dosage.maxDosePerAdministration Upper limit on medication per administration DefinitionUpper limit on medication per administration. The maximum total quantity of a therapeutic substance that may be administered to a subject per administration. This is intended for use as an adjunct to the dosage when there is an upper cap. For example, a body surface area related dose with a maximum amount, such as 1.5 mg/m2 (maximum 2 mg) IV over 5 – 10 minutes would have doseQuantity of 1.5 mg/m2 and maxDosePerAdministration of 2 mg.

maxDosePerLifetime | Σ I | 0..1 | SimpleQuantity | There are no (further) constraints on this element Element idMedicationStatement.dosage.maxDosePerLifetime Upper limit on medication per lifetime of the patient DefinitionUpper limit on medication per lifetime of the patient. The maximum total quantity of a therapeutic substance that may be administered per lifetime of the subject. The context of use may frequently define what kind of quantity this is and therefore what kind of units can be used. The context of use may also restrict the values for the comparator.

MedicationStatementPSON (MedicationStatement) | I | MedicationStatement | Element idMedicationStatement Record of medication being taken by a patient DefinitionA record of a medication that is being consumed by a patient. A MedicationStatement may indicate that the patient may be taking the medication now or has taken the medication in the past or will be taking the medication in the future. The source of this information can be the patient, significant other (such as a family member or spouse), or a clinician. A common scenario where this information is captured is during the history taking process during a patient visit or stay. The medication information may come from sources such as the patient's memory, from a prescription bottle, or from a list of medications the patient, clinician or other party maintains. The primary difference between a medication statement and a medication administration is that the medication administration has complete administration information and is based on actual administration information from the person who administered the medication. A medication statement is often, if not always, less specific. There is no required date/time when the medication was administered, in fact we only know that a source has reported the patient is taking this medication, where details such as time, quantity, or rate or even medication product may be incomplete or missing or less precise. As stated earlier, the medication statement information may come from the patient's memory, from a prescription bottle or from a list of medications the patient, clinician or other party maintains. Medication administration is more formal and is not missing detailed information. Jurisdictions mapping prescription data into FHIR profiles for the patient summary should use the MedicationRequest resource. Use of the MedicationStatement profile should be reserved for communicating a statement about the patient's usage of the medication that is ultimately provided by a patient, significant other, or a clinican.

id | Σ | 0..1 | string | There are no (further) constraints on this element Element idMedicationStatement.id Logical id of this artifact DefinitionThe logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes. The only time that a resource does not have an id is when it is being submitted to the server using a create operation. |
meta | S Σ | 1..1 | Meta | There are no (further) constraints on this element Element idMedicationStatement.meta Metadata about the resource 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.

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. 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.

versionId | Σ | 0..1 | id | There are no (further) constraints on this element Element idMedicationStatement.meta.versionId Version specific identifier DefinitionThe version specific identifier, as it appears in the version portion of the URL. This value changes when the resource is created, updated, or deleted. The server assigns this value, and ignores what the client specifies, except in the case that the server is imposing version integrity on updates/deletes.
|
lastUpdated | Σ | 0..1 | instant | There are no (further) constraints on this element Element idMedicationStatement.meta.lastUpdated When the resource version last changed DefinitionWhen the resource last changed - e.g. when the version changed. This value is always populated except when the resource is first being created. The server / resource manager sets this value; what a client provides is irrelevant. This is equivalent to the HTTP Last-Modified and SHOULD have the same value on a read interaction.
|
source | Σ | 0..1 | uri | There are no (further) constraints on this element Element idMedicationStatement.meta.source Identifies where the resource comes from DefinitionA uri that identifies the source system of the resource. This provides a minimal amount of Provenance information that can be used to track or differentiate the source of information in the resource. The source may identify another FHIR server, document, message, database, etc. In the provenance resource, this corresponds to Provenance.entity.what[x]. The exact use of the source (and the implied Provenance.entity.role) is left to implementer discretion. Only one nominated source is allowed; for additional provenance details, a full Provenance resource should be used. This element can be used to indicate where the current master source of a resource that has a canonical URL if the resource is no longer hosted at the canonical URL.

profile | S Σ | 1..* | canonical(StructureDefinition) | There are no (further) constraints on this element Element idMedicationStatement.meta.profile Profiles this resource claims to conform to DefinitionA list of profiles (references to StructureDefinition resources) that this resource claims to conform to. The URL is a reference to StructureDefinition.url. It is up to the server and/or other infrastructure of policy to determine whether/how these claims are verified and/or updated over time. The list of profile URLs is a set. canonical(StructureDefinition) Constraints

security | Σ | 0..* | CodingBinding | There are no (further) constraints on this element Element idMedicationStatement.meta.security Security Labels applied to this resource DefinitionSecurity labels applied to this resource. These tags connect specific resources to the overall security policy and infrastructure. The security labels can be updated without changing the stated version of the resource. The list of security labels is a set. Uniqueness is based the system/code, and version and display are ignored. Security Labels from the Healthcare Privacy and Security Classification System.
|
tag | Σ | 0..* | Coding | There are no (further) constraints on this element Element idMedicationStatement.meta.tag Tags applied to this resource DefinitionTags applied to this resource. Tags are intended to be used to identify and relate resources to process and workflow, and applications are not required to consider the tags when interpreting the meaning of a resource. The tags can be updated without changing the stated version of the resource. The list of tags is a set. Uniqueness is based the system/code, and version and display are ignored. Codes that represent various types of tags, commonly workflow-related; e.g. "Needs review by Dr. Jones".
|
implicitRules | Σ ?! | 0..1 | uri | There are no (further) constraints on this element Element idMedicationStatement.implicitRules A set of rules under which this content was created 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. 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.
|
language | 0..1 | codeBinding | There are no (further) constraints on this element Element idMedicationStatement.language Language of the resource content DefinitionThe base language in which the resource is written. 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). A human language.
| |
text | 0..1 | Narrative | There are no (further) constraints on this element Element idMedicationStatement.text Text summary of the resource, for human interpretation Alternate namesnarrative, html, xhtml, display 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. 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.
| |
contained | 0..* | Resource | There are no (further) constraints on this element Element idMedicationStatement.contained Contained, inline Resources Alternate namesinline resources, anonymous resources, contained resources 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. 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.

RenderedDosageInstruction | I | 0..1 | Extension | Element idMedicationStatement.extension:RenderedDosageInstruction Extension for representing rendered dosage instruction. Alternate namesextensions, user content DefinitionA free form textual specification generated from the input specifications as created by the provider.This is made up of either an 'Ad-hoc instruction' or 'Textual rendition of the structured dosage lines', plus route, dosage unit, and other pertinent administration information specified by the provider. Use of structured fields for dosage instructions is heavily encouraged by this specification to promote interoperability of patient summaries. However, this extension is provided to make implementers aware that legacy medication data may come from some systems in this format. This extension is used by PrescribeIT implementations when the system has difficulty sending very complex dosage instructions in the form of structured data. Implementers are encouraged to read the PrescribeIT Specification (https://specs.prescribeit.ca/R5.0/erx/extension-ext-medication-rendered-dosage.html) to understand the context around its use. http://prescribeit.ca/fhir/StructureDefinition/ext-rendered-dosage-instruction Constraints

modifierExtension | ?! I | 0..* | Extension | There are no (further) constraints on this element Element idMedicationStatement.modifierExtension Extensions that cannot be ignored Alternate namesextensions, user content 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). 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. 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.

status | S Σ ?! | 1..1 | codeBinding | Element idMedicationStatement.status active | completed | entered-in-error | intended | stopped | on-hold | unknown | not-taken DefinitionA code representing the patient or other source's judgment about the state of the medication used that this statement is about. Generally, this will be active or completed. In the scope of the IPS the entered-in-error concept is not allowed. Implementors should be aware that the shift to R5 MedicationUsage will also involve a new value set for status that is constrained to: recorded, entered-in-error, and draft. A coded concept indicating the current status of a MedicationStatement.
|
statusReason | 0..* | CodeableConcept | There are no (further) constraints on this element Element idMedicationStatement.statusReason Reason for current status DefinitionCaptures the reason for the current state of the MedicationStatement. This is generally only used for "exception" statuses such as "not-taken", "on-hold", "cancelled" or "entered-in-error". The reason for performing the event at all is captured in reasonCode, not here. A coded concept indicating the reason for the status of the statement.

category | Σ | 0..1 | CodeableConceptBinding | There are no (further) constraints on this element Element idMedicationStatement.category Type of medication usage DefinitionIndicates where the medication is expected to be consumed or administered. 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. A coded concept identifying where the medication included in the MedicationStatement is expected to be consumed or administered.

medication[x] | S Σ | 1..1 | Element idMedicationStatement.medication[x] What medication was taken DefinitionIdentifies the medication being administered or the reason for absent or unknown Medication. This is either a link to a resource representing the details of the medication or a simple attribute carrying a code. To improve global interoperability is strongly encouraged that the reference to a medication resource is used, limiting the usage of the medicationCodeableConcept only to the cases in which no other information than a simple code is available. Work is underway to define the pan-Canadian terminology that will be preferred and/or socialized for this element. Unordered, Closed, by $this(Type) BindingA coded concept identifying the substance or product being taken.

medicationReference | S Σ | 0..1 | Reference(MedicationPSON) | Element idMedicationStatement.medication[x]:medicationReference What medication was taken DefinitionIdentifies the medication being administered or the reason for absent or unknown Medication. This is either a link to a resource representing the details of the medication or a simple attribute carrying a code. To improve global interoperability is strongly encouraged that the reference to a medication resource is used, limiting the usage of the medicationCodeableConcept only to the cases in which no other information than a simple code is available. IPS-UV Note: If only a code is specified, then it needs to be a code for a specific product. If more information is required, then the use of the medication resource is recommended. For example, if you require form or lot number, then you must reference the Medication resource.

This describes a categorical negated statement (e.g., "No known medications") Because the IPS-UV value set on this slice is extensible, it can be used to supply other medication codes when only a simple code is available. For all CodeableConcepts, at least one of coding or text must be present. If coding contains only a display value (no code) then CodeableConcept must include text.

reference | S Σ I | 1..1 | string | There are no (further) constraints on this element Element idMedicationStatement.subject.reference Literal reference, Relative, internal or absolute URL DefinitionA reference to a location at which the other resource is found. The reference may be a relative reference, in which case it is relative to the service base URL, or an absolute URL that resolves to the location where the resource is found. The reference may be version specific or not. If the reference is not to a FHIR RESTful server, then it should be assumed to be version specific. Internal fragment references (start with '#') refer to contained resources. Using absolute URLs provides a stable scalable approach suitable for a cloud/web context, while using relative/logical references provides a flexible approach suitable for use when trading across closed eco-system boundaries. Absolute URLs do not need to point to a FHIR RESTful server, though this is the preferred approach. If the URL conforms to the structure "/[type]/[id]" then it should be assumed that the reference is to a FHIR RESTful server.
|
type | Σ | 0..1 | uriBinding | There are no (further) constraints on this element Element idMedicationStatement.subject.type Type the reference refers to (e.g. "Patient") DefinitionThe expected type of the target of the reference. If both Reference.type and Reference.reference are populated and Reference.reference is a FHIR URL, both SHALL be consistent. The type is the Canonical URL of Resource Definition that is the type this reference refers to. References are URLs that are relative to http://hl7.org/fhir/StructureDefinition/ e.g. "Patient" is a reference to http://hl7.org/fhir/StructureDefinition/Patient. Absolute URLs are only allowed for logical models (and can only be used in references in logical models, not resources). This element is used to indicate the type of the target of the reference. This may be used which ever of the other elements are populated (or not). In some cases, the type of the target may be determined by inspection of the reference (e.g. a RESTful URL) or by resolving the target of the reference; if both the type and a reference is provided, the reference SHALL resolve to a resource of the same type as that specified. Aa resource (or, for logical models, the URI of the logical model).
|
identifier | Σ | 0..1 | Identifier | There are no (further) constraints on this element Element idMedicationStatement.subject.identifier Logical reference, when literal reference is not known DefinitionAn identifier for the target resource. This is used when there is no way to reference the other resource directly, either because the entity it represents is not available through a FHIR server, or because there is no way for the author of the resource to convert a known identifier to an actual location. There is no requirement that a Reference.identifier point to something that is actually exposed as a FHIR instance, but it SHALL point to a business concept that would be expected to be exposed as a FHIR instance, and that instance would need to be of a FHIR resource type allowed by the reference. When an identifier is provided in place of a reference, any system processing the reference will only be able to resolve the identifier to a reference if it understands the business context in which the identifier is used. Sometimes this is global (e.g. a national identifier) but often it is not. For this reason, none of the useful mechanisms described for working with references (e.g. chaining, includes) are possible, nor should servers be expected to be able resolve the reference. Servers may accept an identifier based reference untouched, resolve it, and/or reject it - see CapabilityStatement.rest.resource.referencePolicy. When both an identifier and a literal reference are provided, the literal reference is preferred. Applications processing the resource are allowed - but not required - to check that the identifier matches the literal reference Applications converting a logical reference to a literal reference may choose to leave the logical reference present, or remove it. Reference is intended to point to a structure that can potentially be expressed as a FHIR resource, though there is no need for it to exist as an actual FHIR resource instance - except in as much as an application wishes to actual find the target of the reference. The content referred to be the identifier must meet the logical constraints implied by any limitations on what resource types are permitted for the reference. For example, it would not be legitimate to send the identifier for a drug prescription if the type were Reference(Observation|DiagnosticReport). One of the use-cases for Reference.identifier is the situation where no FHIR representation exists (where the type is Reference (Any).

effective[x] | S Σ | 1..1 | There are no (further) constraints on this element Element idMedicationStatement.effective[x] The date/time or interval when the medication is/was/will be taken DefinitionThe interval of time during which it is being asserted that the patient is/was/will be taking the medication (or was not taking, when the MedicationStatement.taken element is No). This attribute reflects the period over which the patient consumed the medication and is expected to be populated on the majority of Medication Statements. If the medication is still being taken at the time the statement is recorded, the "end" date will be omitted. The date/time attribute supports a variety of dates - year, year/month and exact date. If something more than this is required, this should be conveyed as text.

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 can 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). 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. 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.

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. Additional information about administration or preparation of the medication should be included as text. Note that FHIR strings SHALL NOT exceed 1MB in size

additionalInstruction | Σ | 0..* | CodeableConcept | There are no (further) constraints on this element Element idMedicationStatement.dosage.additionalInstruction Supplemental instruction or warnings to the patient - e.g. "with meals", "may cause drowsiness" DefinitionSupplemental instructions to the patient on how to take the medication (e.g. "with meals" or"take half to one hour before food") or warnings for the patient about the medication (e.g. "may cause drowsiness" or "avoid exposure of skin to direct sunlight or sunlamps"). Additional instruction is intended to be coded, but where no code exists, the element could include text. For example, "Swallow with plenty of water" which might or might not be coded. Information about administration or preparation of the medication (e.g. "infuse as rapidly as possibly via intraperitoneal port" or "immediately following drug x") should be populated in dosage.text. A coded concept identifying additional instructions such as "take with water" or "avoid operating heavy machinery".

timing | S Σ | 0..1 | Timing | There are no (further) constraints on this element Element idMedicationStatement.dosage.timing When medication should be administered DefinitionWhen medication should be administered. The timing schedule for giving the medication to the patient. This data type allows many different expressions. For example: "Every 8 hours"; "Three times a day"; "1/2 an hour before breakfast for 10 days from 23-Dec 2011:"; "15 Oct 2013, 17 Oct 2013 and 1 Nov 2013". 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. This attribute might not always be populated while the Dosage.text is expected to be populated. If both are populated, then the Dosage.text should reflect the content of the Dosage.timing.

asNeeded[x] | Σ | 0..1 | There are no (further) constraints on this element Element idMedicationStatement.dosage.asNeeded[x] Take "as needed" (for x) DefinitionIndicates whether the Medication is only taken when needed within a specific dosing schedule (Boolean option), or it indicates the precondition for taking the Medication (CodeableConcept). Can express "as needed" without a reason by setting the Boolean = True. In this case the CodeableConcept is not populated. Or you can express "as needed" with a reason by including the CodeableConcept. In this case the Boolean is assumed to be True. If you set the Boolean to False, then the dose is given according to the schedule and is not "prn" or "as needed". A coded concept identifying the precondition that should be met or evaluated prior to consuming or administering a medication dose. For example "pain", "30 minutes prior to sexual intercourse", "on flare-up" etc.

If the type is not populated, assume to be "ordered". 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. The kind of dose or rate specified.
|
dose[x] | Σ | 0..1 | There are no (further) constraints on this element Element idMedicationStatement.dosage.doseAndRate.dose[x] Amount of medication per dose DefinitionAmount of medication per dose. The amount of therapeutic or other substance given at one administration event. 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.

rate[x] | Σ | 0..1 | There are no (further) constraints on this element Element idMedicationStatement.dosage.doseAndRate.rate[x] Amount of medication per unit of time DefinitionAmount of medication per unit of time. 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. 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. It is possible to specify a rate over time (for example, 100 ml/hour) using either the rateRatio and rateQuantity. The rateQuantity approach requires systems to have the capability to parse UCUM grammer where ml/hour is included rather than a specific ratio where the time is specified as the denominator. Where a rate such as 500ml over 2 hours is specified, the use of rateRatio may be more semantically correct than specifying using a rateQuantity of 250 mg/hour.

The maximum total quantity of a therapeutic substance that may be administered to a subject per administration. This is intended for use as an adjunct to the dosage when there is an upper cap. For example, a body surface area related dose with a maximum amount, such as 1.5 mg/m2 (maximum 2 mg) IV over 5 – 10 minutes would have doseQuantity of 1.5 mg/m2 and maxDosePerAdministration of 2 mg.
