Element id

MedicationRequest.id

Short description

Logical id of this artifact

Definition

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

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.

Short description

Metadata about the resource

Definition

The 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.

Element id

MedicationRequest.implicitRules

Short description

A set of rules under which this content was created

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

Comments

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

MedicationRequest.language

Short description

Language of the resource content

Definition

The base language in which the resource is written.

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).

Data type

Binding

A human language.

Element id

MedicationRequest.text

Short description

Text summary of the resource, for human interpretation

Alternate names

narrative, html, xhtml, display

Definition

A 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.

Comments

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

Short description

Contained, inline Resources

Alternate names

inline resources, anonymous resources, contained resources

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.

Comments

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

Additional content defined by implementations

Alternate names

Definition

May 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.

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.

Comments

The URI may be an OID (urn:oid:...) or a UUID (urn:uuid:...). OIDs and UUIDs SHALL be references to the HL7 OID registry. Otherwise, the URI should come from HL7's list of FHIR defined special URIs or it should reference to some definition that establishes the system clearly and unambiguously.

Version of the system - if relevant

Definition

The version of the code system which was used when choosing this code. Note that a well-maintained code system does not need the version reported, because the meaning of codes is consistent across versions. However this cannot consistently be assured, and when the meaning is not guaranteed to be consistent, the version SHOULD be exchanged.

Comments

Where the terminology does not clearly define what string should be used to identify code system versions, the recommendation is to use the date (expressed in FHIR date format) on which that version was officially published as the version date.

If this coding was chosen directly by the user

Definition

Indicates that this coding was chosen by a user directly - e.g. off a pick list of available items (codes or displays).

Requirements

This has been identified as a clinical safety criterium - that this exact system/code pair was chosen explicitly, rather than inferred by the system based on some rules or language processing.

Comments

Amongst a set of alternatives, a directly chosen code is the most appropriate starting point for new translations. There is some ambiguity about what exactly 'directly chosen' implies, and trading partner agreement may be needed to clarify the use of this element and its consequences more completely.

extensions, user content

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 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).

Requirements

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

Short description

Description of identifier

Definition

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

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.

Definition

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

The value that is unique

Definition

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

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. Identifier.value is to be treated as case sensitive unless knowledge of the Identifier.system allows the processer to be confident that non-case-sensitive processing is safe.

Definition

A code specifying the current state of the order. Generally, this will be active or completed state.

code	Definition
active	The prescription is 'actionable', but not all actions that are implied by it have occurred yet. It has not been dispensed or filled.
cancelled	The prescription is to be cancelled or it has been cancelled been withdrawn before any administrations have occurred. Prescriptions in the process of being cancelled will be regarded as active until all actions are complete.
stopped	Actions implied by the prescription are to be permanently halted, before all of the administrations occurred. This should not be used if the original order was entered in error
completed	All actions that are implied by the prescription have occurred.

Logical medicationRequest status transitions

This state transition diagram is an enhancement over the generic State Machine defined within the FHIR specification. It includes the status values associated with a medication request with transitions applicable to a UK implementation.

Plain text representation of the concept

Definition

A human language representation of the concept as seen/selected/uttered by the user who entered the data and/or which represents the intended meaning of the user.

Requirements

The codes from the terminologies do not always capture the correct meaning with all the nuances of the human using them, or sometimes there is no appropriate code at all. In these cases, the text is used to capture the full meaning of the source.

Comments

Very often the text is the same as a displayName of one of the codings.

Short description

The complete dosage instruction as a human readable string.

Definition

The complete dosage instruction as a human readable string.

<div class="nhsd-a-box nhsd-a-box--bg-light-blue nhsd-!t-margin-bottom-6 nhsd-t-body"> <strong>Recommendation</strong>: Use the <a href='DosetoTextTranslation'>translation algorithm</a> published within this guide to create a string from the coded Dosage elements. It is planned for this translation algorithm to be available as an API. </div>

For example;

<text value="1 tablet - every 6 hours - oral" />

Where additional dosage instructions need to be conveyed that cannot be described using any other element of the Dosage structure, then append these to the end of the translated dosage text.

For example, the instruction to “infuse as rapidly as possibly via intraperitoneal port” is not a coded term so cannot be shared as a additionalInstruction. It would neither be appropriate as a patientInstruction string.

For example;

<text value="{the dosage elements translated as text} - infuse as rapidly as possibly via intraperitoneal port" />

For example, the instruction “immediately following drug {X}”), where {X} is the name of a drug, is neither suitable as a additionalInstruction nor patientInstruction.

For example;

<text value="500 milligrams - once - oral - immediately following drug {X}" />

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. Additional information about administration or preparation of the medication should be included as text.

Element id

MedicationRequest.dosageInstruction.timing

Short description

When medication should be administered

Definition

Adding constraints, bounds or limits to a dosage instruction.

Requirements

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.

Comments

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.

BID | TID | QID | AM | PM | QD | QOD | +

Definition

A code for the timing schedule (or just text in code.text). Some codes such as BID are ubiquitous, but many institutions define their own additional codes. If a code is provided, the code is understood to be a complete statement of whatever is specified in the structured timing data, and either the code or the data may be used to interpret the Timing, with the exception that .repeat.bounds still applies over the code (and is not contained in the code).

Comments

BID etc. are defined as 'at institutionally specified times'. For example, an institution may choose that BID is "always at 7am and 6pm". If it is inappropriate for this choice to be made, the code BID should not be used. Instead, a distinct organization-specific code should be used in place of the HL7-defined BID code and/or a structured representation should be used (in this case, specifying the two event times).

MedicationRequest.dosageInstruction.asNeeded[x]

Short description

Take "as needed" (for x)

Definition

The asNeeded structure can be used to define a simple “as required” (or “pro re nata” expressed as “PRN” for those who still prefer to use Latin abbreviations) instructions.

In this case use the asNeededBoolean option. The absence of asNeededBoolean is equivalent to where asNeededBoolean has a value of false.

The asNeededCodeableConcept option is used to bound the dosage instruction to a coded term. Any number of coded terms can be used from the SNOMED-CT hierarchy as a descendant of 404684003 Clinical Finding (finding). An extensive medication-as-needed-reason value-set is defined within FHIR which is a subset of the SNOMED-CT clinical findings hierarchy.

Comments

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".

Binding

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.

Any route can be used from the SNOMED-CT hierarchy as a descendant of the concept 284009009 Route of administration value (qualifier value).

<!-- Route -->

        <code value="78421000"/>
        <display value="intramuscular route"/>
    </coding>
</route>

Requirements

A code specifying the route or physiological path of administration of a therapeutic agent into or onto a patient's body.

Comments

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.

Data type

Binding

A coded concept describing the route or physiological path of administration of a therapeutic agent into or onto the body of a subject.

Technique for administering medication

Definition

The 999000041000001103 ePrescribing method simple reference set (foundation metadata concept) reference set collates the commonly used terms for method for use in the United Kingdom.

Whilst a FHIR value-set for method does exist, together with two separate hierarchies within SNOMED-CT (Dose form administration method and Dosing instruction fragment), it is recommended to use the ePrescribing reference set in the first instance.

</method>

Use of synonyms

In most instances it is anticipated that the UK Preferred term should be the term applied to SNOMED CT concepts However for some cases, for example the anatomically correct SNOMED-CT term may not be easily understood by the patient or clinician, the use of a synonym may be preferred.

Guidance for using terms that are not preferred terms is available within the published document Guidance on the use of CodeableConcept.

Requirements

A coded value indicating the method by which the medication is introduced into or onto the body. Most commonly used for injections. For examples, Slow Push; Deep IV.

Comments

Terminologies used often pre-coordinate this term with the route and or form of administration.

MedicationRequest.dosageInstruction.doseAndRate

Short description

Amount of medication administered

Definition

Dose and Rate elements within the Dosage structure have been combined within the R4 standard, but their underlying use and purpose is the same as per R4.

A dose or rate of medication can be described via one of the following methods. In both instances when considering Units of Measure note that UCUM is preferred.

Sub-element: `Dosage.doseAndRate.doseQuantity`

The amount of medication per dose, as a simple coded quantity.

<!-- Example A: 1 capsule -->
<doseAndRate>
    <doseQuantity>
        <value value="1"/>
        <unit value="capsule"/>
        <system value="http://snomed.info/sct"/>
        <code value="732937005"/>
    </doseQuantity>
</doseAndRate>

<!-- Example B: 30 milligrams -->
<doseAndRate>
    <doseQuantity>
        <value value="30"/>
        <unit value="milligram"/>
        <system value="http://unitsofmeasure.org"/>
        <code value="mg"/>
    </doseQuantity>
</doseAndRate>

Sub-element: `Dosage.doseAndRate.doseRange`

A dose that may be in a given low / high range.

<!-- for a dose between 7.5 to 30 milligram -->
<doseAndRate>
    <doseRange>
        <low>
            <value value="7.5"/>
            <unit value="milligram"/>
            <code value="mg"/>
            <system value="http://unitsofmeasure.org"/>
        </low>
        <high>
            <value value="30"/>
            <unit value="milligram"/>
            <code value="mg"/>
            <system value="http://unitsofmeasure.org"/>
        </high>
    </doseRange>
</doseAndRate>

A rate-based quantity, such as 30 ml per hour, can be expressed as a rateRatio with coded numerator and denominator values.

Where the unit of measure for the ratio is defined within UCUM (see Common UCUM Units), for example, “milliliter per hour”, it can also be expressed using the simpler rateQuantity structure.

Sub-element: `Dosage.doseAndRate.rateRatio`

Where the rate is expressed as coded numerator and denominator values.

at a rate of 30ml/hour using rateRatio

<doseAndRate>
 <rateRatio>
  <numerator>
   <value value="30"/>
   <unit value="millilitre"/>
   <system value="http://unitsofmeasure.org"/>

   <value value="1"/>
   <unit value="hour"/>
   <system value="http://unitsofmeasure.org"/>
   <code value="h"/>
  </denominator>
 </rateRatio>
</doseAndRate>

Sub-element: `Dosage.doseAndRate.rateQuantity`

Where the unit of measure applicable to a rate is defined within UCUM which is mathematically equivalent to defining the rate using the more complex rateRatio structure.

at a rate of 30ml/hour using rateQuantity

<rateQuantity>
 <value value="30"/>
 <unit value="milliliters per hour"/>
 <system value="http://unitsofmeasure.org"/>
 <code value="mL/h"/>
</rateQuantity>

at a rate of 1mcg/kg/hour using rateQuantity

<doseAndRate>
 <rateQuantity>
  <value value="1"/>
  <unit value="microgram per kilogram per hour"/>
  <system value="http://unitsofmeasure.org"/>
  <code value="ug/kg/h"/>
 </rateQuantity>
</doseAndRate>

Sub-element: `Dosage.doseAndRate.rateRange`

Where the unit of measure applicable to a rate range is defined within UCUM the rateRange structure can be used.

give at 1-2 litres per minute using rateRange

<doseAndRate>
 <rateRange>
  <low>
   <value value="1"/>

Amount of medication per dose

Definition

Amount of medication per dose.

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.

Amount of medication per unit of time

Definition

Amount of medication per unit of time.

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.

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 maxDosePerPeriod is defined for each dosage instruction. For a multi-sequence instruction it would therefore be possible to define different maximum dosing periods within different sequences of the complete instruction.

An example would be Anagrelide for which a single dose should not exceed 2.5 mg. The maxDosePerAdministration is defined as 2.5mg.

In many scenarios it is expected that the dosage.doseRange would be used instead of maxDosePerAdministration.

The maxDosePerAdministration is defined for each dosage instruction. For a multi-sequence instruction it would therefore be possible to define different maximum dose administrations within different sequences of the complete instruction.

Comments

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.

The maxDosePerLifetime can be defined for each dosage instruction; which, for a multi-sequence instruction is illogical, as any maxDosePerLifetime is equally applicable to all dosage sequence that relate to the single medication coded concept.

Requirements

Indicates when the Prescription becomes valid, and when it ceases to be a dispensable Prescription.

Comments

It reflects the prescribers' perspective for the validity of the prescription. Dispenses must not be made against the prescription outside of this period. The lower-bound of the Dispensing Window signifies the earliest date that the prescription can be filled for the first time. If an upper-bound is not specified then the Prescription is open-ended or will default to a stale-date based on regulations.

MedicationRequest.dispenseRequest.numberOfRepeatsAllowed

Short description

Number of refills authorized

Definition

The number of repeat issues authorised if specified. <br> <b>MUST</b> be present where a continuous or continuous-repeat-dispensing is authorised for a defined number of issues. <br> <b>MUST</b> NOT be specified where the number of repeat issues has not been defined. Therefore, the numberOfRepeats allowed is the total number of allowed issues. See also <a href="#repeatInformation">extension repeatInformation</a>

For continuous orders and continuous-repeat-dispensing with intent=reflex-order (i.e., orders sent from EPS to pharmacists) this <b>MUST</b> be zero. The numberOfRepeatsAllowed in the extension to basedOn can be used to convey this information to inform patients that they need to re-order the medication.

Example for a continuous issue:


"dispenseRequest": {
        "numberOfRepeatsAllowed": 0
    }

Example for a continuous-repeat-dispensing issue with intent of original-order:


"dispenseRequest": {
        "numberOfRepeatsAllowed": 2
    }

This will result in a total of three issues of the medication.

MedicationRequest.dispenseRequest.expectedSupplyDuration

Short description

Days Supply

Definition

The expectedSupplyDuration entity is required for repeat dispensing (repeatable) prescriptions only.

The expectedSupplyDuration element defines the expected duration, in days, of each issue of the prescription. A default value of 28 can be used which must be amendable by the prescriber when required. The value must be an integer value greater than zero. A sensible upper limit validation should be included within the System. If this value is omitted, the Spine will assume a value of 28.

"dispenseRequest": {
          ...
          "expectedSupplyDuration": {
            "value": 28,
            "unit": "days",
            "system": "http://unitsofmeasure.org",
            "code": "d"
          }
      }

Comments

In some situations, this attribute may be used instead of quantity to identify the amount supplied by how long it is expected to last, rather than the physical quantity issued, e.g. 90 days supply of medication (based on an ordered dosage). When possible, it is always better to specify quantity, as this tends to be more precise. expectedSupplyDuration will always be an estimate that can be influenced by external factors.

A list of events of interest in the lifecycle

Definition

Links to Provenance records for past versions of this resource or fulfilling request or event resources that identify key state transitions or updates that are likely to be relevant to a user looking at the current version of the resource.

Comments

This might not include provenances for all versions of the request – only those deemed “relevant” or important. This SHALL NOT include the provenance associated with this current version of the resource. (If that provenance is deemed to be a “relevant” change, it will need to be added as part of a later update. 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.).

Short description

active | cancelled | stopped

Definition

A code specifying the current state of the order. Generally, this will be active or completed state.

code	Definition
active	The prescription is 'actionable', but not all actions that are implied by it have occurred yet. It has not been dispensed or filled.
cancelled	The prescription is to be cancelled or it has been cancelled been withdrawn before any administrations have occurred. Prescriptions in the process of being cancelled will be regarded as active until all actions are complete.
stopped	Actions implied by the prescription are to be permanently halted, before all of the administrations occurred. This should not be used if the original order was entered in error
completed	All actions that are implied by the prescription have occurred.

Element id

MedicationRequest.dosageInstruction.doseAndRate

Short description

Amount of medication administered

Definition

Dose and Rate elements within the Dosage structure have been combined within the R4 standard, but their underlying use and purpose is the same as per R4.

A dose or rate of medication can be described via one of the following methods. In both instances when considering Units of Measure note that UCUM is preferred.

Sub-element: `Dosage.doseAndRate.doseQuantity`

The amount of medication per dose, as a simple coded quantity.

<!-- Example A: 1 capsule -->
<doseAndRate>
    <doseQuantity>
        <value value="1"/>
        <unit value="capsule"/>
        <system value="http://snomed.info/sct"/>
        <code value="732937005"/>
    </doseQuantity>
</doseAndRate>

<!-- Example B: 30 milligrams -->
<doseAndRate>
    <doseQuantity>
        <value value="30"/>
        <unit value="milligram"/>
        <system value="http://unitsofmeasure.org"/>
        <code value="mg"/>
    </doseQuantity>
</doseAndRate>

Sub-element: `Dosage.doseAndRate.doseRange`

A dose that may be in a given low / high range.

<!-- for a dose between 7.5 to 30 milligram -->
<doseAndRate>
    <doseRange>
        <low>
            <value value="7.5"/>
            <unit value="milligram"/>
            <code value="mg"/>
            <system value="http://unitsofmeasure.org"/>
        </low>
        <high>
            <value value="30"/>
            <unit value="milligram"/>
            <code value="mg"/>
            <system value="http://unitsofmeasure.org"/>
        </high>
    </doseRange>
</doseAndRate>

A rate-based quantity, such as 30 ml per hour, can be expressed as a rateRatio with coded numerator and denominator values.

Where the unit of measure for the ratio is defined within UCUM (see Common UCUM Units), for example, “milliliter per hour”, it can also be expressed using the simpler rateQuantity structure.

Sub-element: `Dosage.doseAndRate.rateRatio`

Where the rate is expressed as coded numerator and denominator values.

at a rate of 30ml/hour using rateRatio

<doseAndRate>
 <rateRatio>
  <numerator>
   <value value="30"/>
   <unit value="millilitre"/>
   <system value="http://unitsofmeasure.org"/>
   <code value="mL"/>
  </numerator>
  <denominator>
   <value value="1"/>
   <unit value="hour"/>
   <system value="http://unitsofmeasure.org"/>
   <code value="h"/>
  </denominator>
 </rateRatio>
</doseAndRate>

Sub-element: `Dosage.doseAndRate.rateQuantity`

Where the unit of measure applicable to a rate is defined within UCUM which is mathematically equivalent to defining the rate using the more complex rateRatio structure.

at a rate of 30ml/hour using rateQuantity

<rateQuantity>
 <value value="30"/>
 <unit value="milliliters per hour"/>
 <system value="http://unitsofmeasure.org"/>
 <code value="mL/h"/>
</rateQuantity>

at a rate of 1mcg/kg/hour using rateQuantity

<doseAndRate>
 <rateQuantity>
  <value value="1"/>
  <unit value="microgram per kilogram per hour"/>
  <system value="http://unitsofmeasure.org"/>
  <code value="ug/kg/h"/>
 </rateQuantity>
</doseAndRate>

Sub-element: `Dosage.doseAndRate.rateRange`

Where the unit of measure applicable to a rate range is defined within UCUM the rateRange structure can be used.

give at 1-2 litres per minute using rateRange

<doseAndRate>
 <rateRange>
  <low>
   <value value="1"/>
   <unit value="liter per minute"/>
   <system value="http://unitsofmeasure.org"/>
   <code value="L/min"/>
  </low>
  <high>
   <value value="2"/>
   <unit value="liter per minute"/>

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 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).

Usage Notes: This integer does not include the original order dispense. This means that if an order indicates dispense 30 tablets plus "3 repeats", then the order can be dispensed a total of 4 times and the patient can receive a total of 120 tablets. A prescriber may explicitly say that zero refills are permitted after the initial dispense. ```json "extension": [ { "url": "https://fhir.nhs.uk/StructureDefinition/Extension-EPS-RepeatInformation", "extension": [ { "url": "numberOfRepeatsAllowed", "valueInteger": 2 } ] } ] ```

MedicationRequest.groupIdentifier

Definition The purpose of the Short Form Prescription ID is to identify the prescription during its lifecycle within the Spine (i.e. prescribe, dispense & claim). The prescription UUID is retained to provide the link through to the Spine medication record within the PSIS and must be included as the first identifier within the prescription message. The format of the Short Form Prescription ID is as follows; `--` Where; `` is a locally generated random number each time a Prescription ID is generated of length 6 hexadecimal characters. `` is the unique ODS code for the practice or clinic code (aka cost centre) as defined within the Spine SDS of length 6 characters. Where the prescriber ODS code is shorter than 6 characters it must be zero-padded up to six characters from the start of the ODS code, e.g. “0A1B2C”. `` is an incremental sequence number starting from 00000 that is reset after FFFFF back to zero of length 5 hexadecimal characters. For systems that support multiple practices or clinics, a sequence number per practice/clinic is required. This is to ensure uniqueness of prescriptions within the Spine EPS component during the prescription lifecycle. `` is calculated on the entire ID using the ISO/IEC 7064:2003 MOD 37-2 standard. The check digit algorithm is identical to that using for EPS Release 1. Note. Hyphens are always included to separate the ID into 3 blocks of 6 characters. Note. The implementation of the MOD 37-2 standard uses a “+” character for char 36 opposed to a “*” character. Short Form Prescription ID example (for illustration purposes only); **83C40E-A23856-00123W** ```json "groupIdentifier": { ...

MedicationRequest.note

Definition Clinical information relating to a prescribed medication item that cannot be conveyed within dosage instructions is populated within `note` field. Examples of dispensing notes are: - To explain changes in dosage, for example, “Dosage has been increased on advice of the hospital”. - "Tell patient to stop their statin whilst on this anitbiotic" - "hospital consultant has confirmed dual treatment" One scenario where `note` must be populated is when the current prescribed medication item is the last authorised repeat of that medication within a repeat prescribing cycle. Appropriate text, such as “Last authorised repeat” must be included within the `note` to inform the dispenser and to allow the dispenser to communicate to the patient or patient representative. Note that for repeat dispensing, the ‘numberOfPrescriptionsIssued’ element also conveys this information. ```json "note": [ { "text": "Tell patient to stop their statin whilst on this anitbiotic" } ], ```

MedicationRequest.dosageInstruction

Definition The content of the `dosageInstruction` should follow guidance in [Digital Medicines Dosage](https://simplifier.net/guide/ukcoreimplementationguideformedicines/ElementDosage). `dosageInstruction.text` **MUST** be supplied and is a human readable version of the structured dose as would be printed on a paper prescription. The use of a generic default value, for example “Use as directed”, if a value is not entered, is not acceptable from a clinical perspective. The user must be asked to select a dosage instruction from a pick list, type by hand or have the system populate with a valid and clinically safe dosage instruction relevant to the prescribed medication or clinical circumstances. As per BNF guidelines, the dosage must be presented to the user without abbreviation although it may be entered and stored within the PMR in an abbreviated form. Within HL7 messaging, the dosage instruction must be represented without abbreviation. ```json "dosageInstruction": [ { "text": "Inject 10 milligram, once a week, Subcutaneous route, for 10 weeks", "timing": { "repeat": { "boundsDuration": { "value": 10, "unit": "week", "system": "http://unitsofmeasure.org", "code": "wk" }, "frequency": 1, "period": 1, "periodUnit": "wk" } }, "route": { "coding": [ { "system": "http://snomed.info/sct", "code": "34206005", "display": "Subcutaneous route" } ] }, "method": { "coding": [ { "system": "http://snomed.info/sct", "code": "422145002", "display": "Inject" } ] }, "doseAndRate": [ { "doseQuantity": { "value": 10, "unit": "milligram", "system": "http://unitsofmeasure.org", "code": "mg" } } ] } ] ```

Definition May be used to represent additional information that is not part of the basic definition of the element and that modifies the understanding of the element in which it is contained 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 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).

MedicationRequest.dosageInstruction.sequence

Definition A multi-sequence would be required where a dosage instruction changes over a given time schedule, where a dosage instruction includes optional follow-up doses or where a concurrent dosage instruction is required for the same medication at a different dose. Examples below include Prednisolone to treat Bell’s palsy where a dose starts at 60 mg per day for a period of time then reduces by 10 mg per day. This would be described as a sequential dosage instruction. A concurrent dosage example is provided to describe a different dose in the morning to that at midday. #### Sequential Instructions Where the value of sequence is an incremental integer it defines a sequential instruction. #### Concurrent Instructions Where the same integer value of sequence is defines it means a concurrent instruction.

MedicationRequest.dosageInstruction.text

Definition

The complete dosage instruction as a human readable string.

Recommendation: Use the translation algorithm published within this guide to create a string from the coded Dosage elements. It is planned for this translation algorithm to be available as an API.

For example; ```xml ``` Where additional dosage instructions need to be conveyed that cannot be described using any other element of the Dosage structure, then append these to the end of the translated dosage text. For example, the instruction to `“infuse as rapidly as possibly via intraperitoneal port”` is not a coded term so cannot be shared as a `additionalInstruction`. It would neither be appropriate as a `patientInstruction` string. For example; ```xml ``` For example, the instruction `“immediately following drug {X}”)`, where {X} is the name of a drug, is neither suitable as a `additionalInstruction` nor `patientInstruction`. For example; ```xml ```

MedicationRequest.dosageInstruction.doseAndRate

Definition Dose and Rate elements within the Dosage structure have been combined within the R4 standard, but their underlying use and purpose is the same as per R4. A dose or rate of medication can be described via one of the following methods. In both instances when considering Units of Measure note that UCUM is preferred. ### Sub-element: `Dosage.doseAndRate.doseQuantity` The amount of medication per dose, as a [simple coded quantity](http://hl7.org/fhir/datatypes.html#SimpleQuantity). ```xml ``` ### Sub-element: `Dosage.doseAndRate.doseRange` A dose that may be in a given low / high range. ```xml ``` A rate-based quantity, such as _30 ml per hour_, can be expressed as a `rateRatio` with coded numerator and denominator values. Where the unit of measure for the ratio is defined within UCUM (see [Common UCUM Units](https://www.hl7.org/fhir/valueset-UCUM-common.xml)), for example, “milliliter per hour”, it can also be expressed using the simpler `rateQuantity` structure. ### Sub-element: `Dosage.doseAndRate.rateRatio` Where the rate is expressed as coded numerator and denominator values. **at a rate of 30ml/hour using rateRatio** ```xml ``` ### Sub-element: `Dosage.doseAndRate.rateQuantity` Where the unit of measure applicable to a rate is defined within UCUM which is mathematically equivalent to defining the rate using the more complex `rateRatio` structure. **at a rate of 30ml/hour using rateQuantity** ```xml ``` **at a rate of 1mcg/kg/hour using rateQuantity** ```xml ``` ### Sub-element: `Dosage.doseAndRate.rateRange` Where the unit of measure applicable to a rate range is defined within UCUM the `rateRange` structure can be used. **give at 1-2 litres per minute using rateRange** ```xml ```

MedicationRequest.dosageInstruction.maxDosePerPeriod

Definition

Used to define a maxiumum dose over a given time period.

An example would be a Sumatriptan 6mg injection which can be repeated after an hour but not again over a 24 hour period. The `maxDosePerPeriod` is defined as 12mg/24hours. The `maxDosePerPeriod` is defined for each dosage instruction. For a multi-sequence instruction it would therefore be possible to define different maximum dosing periods within different sequences of the complete instruction.

A real-world example of where this would be required has not yet been identified.

Definition

Used to define a maximum dose for a single administration.

An example would be Anagrelide for which a single dose should not exceed 2.5 mg. The `maxDosePerAdministration` is defined as 2.5mg. In many scenarios it is expected that the `dosage.doseRange` would be used instead of `maxDosePerAdministration`. The `maxDosePerAdministration` is defined for each dosage instruction. For a multi-sequence instruction it would therefore be possible to define different maximum dose administrations within different sequences of the complete instruction.

MedicationRequest.dosageInstruction.maxDosePerLifetime

Definition

Used to define the maximum cumulative dose over the lifetime of a patient.

An example would be Daunorubicin which may have a maximum cumulative dose of 600mg/m2 (based on the size of the patient). The `maxDosePerLifetime` is defined as 600 mg/m2. The `maxDosePerLifetime` can be defined for each dosage instruction; which, for a multi-sequence instruction is illogical, as any `maxDosePerLifetime` is equally applicable to all dosage sequence that relate to the single medication coded concept.

Note: If a maxDosePerLifetime statement is required with a multi-sequence instruction, it is recommended to define it within the last / final sequence to ensure that the information is presented at the end of a the complete instruction, rather than th middle which could be overlooked.

MedicationRequest.dispenseRequest.numberOfRepeatsAllowed

Definition An integer indicating the number of times, in addition to the original dispense, (aka refills or repeats) that the patient can receive the prescribed medication. Usage Notes: This integer does not include the original order dispense. This means that if an order indicates dispense 30 tablets plus "3 repeats", then the order can be dispensed a total of 4 times and the patient can receive a total of 120 tablets. A prescriber may explicitly say that zero refills are permitted after the initial dispense. The number of repeat issues authorised if specified.
MUST be present where a `continuous` or `continuous-repeat-dispensing` is authorised for a defined number of issues.
MUST NOT be specified where the number of repeat issues has not been defined. Therefore, the numberOfRepeats allowed is the total number of allowed issues. See also extension repeatInformation For `continuous` orders and `continuous-repeat-dispensing` with intent=`reflex-order` (i.e., orders sent from EPS to pharmacists) this MUST be zero. The `numberOfRepeatsAllowed` in the extension to `basedOn` can be used to convey this information to inform patients that they need to re-order the medication. Example for a `continuous` issue: ```json "dispenseRequest": { "numberOfRepeatsAllowed": 0 } ``` Example for a `continuous-repeat-dispensing` issue with intent of `original-order`: ```json "dispenseRequest": { "numberOfRepeatsAllowed": 2 } ``` This will result in a total of three issues of the medication.

MedicationRequest.substitution

Definition

Within UK healthcare, substitution is not the norm and so this element will normally be set to a default of `false`. Substitution being set to false is a mandatory requirement for EPS.. Substituition is a mandatory requirement for EPS.

Important Note:

Within UK healthcare, substitution is not the norm so the international FHIR definition where "_If nothing is specified substitution may be done._" does not align with UK healthcare prescribing best practice.

It could be unwise to assume all UK implementations will prevent substitution if not explicitly stated, especially if the same clinical system has been previously implemented outside the UK.

UK Core has profiled this element as MANDATORY and MUST have a default boolean value of false to denote substitution is not allowed.

Allowing substitution

Where substitution to be be allowed, set to true. The inclusion of the coded reason is optional as the valueset defined in FHIR is of limited benefit to UK healthcare.
