2. Task.implicitRules
Definition

A reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc.

ShortA set of rules under which this content was created
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.

R5: Task.requestedPeriod (new:Period)

ShortR5: When the task should be performed (new)
Comments

Element Task.requestedPeriod has a context of Task based on following the parent source element upwards and mapping to Task. Element Task.requestedPeriod has no mapping targets in FHIR R4. Typically, this is because the element has been added (is a new element). This is typically used when the Task is not seeking fulfillment of a focus Request, as in that case the period would be specified on the Request and/or in the Task.restriction.period. Instead, it is used for stand-alone tasks.

10. Task.modifierExtension
Definition

An Extension


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).

ShortExtensionExtensions that cannot be ignored
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.

Control0..*
TypeExtension
Is Modifiertrue because Modifier extensions are expected to modify the meaning or interpretation of the resource that contains them
Summaryfalse
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.

    Slice NamedoNotPerform
    Definition

    R5: Task.doNotPerform (new:boolean)

    ShortR5: True if Task is prohibiting action (new)
    Comments

    Element Task.doNotPerform has a context of Task based on following the parent source element upwards and mapping to Task. Element Task.doNotPerform has no mapping targets in FHIR R4. Typically, this is because the element has been added (is a new element). An externally-defined extension that has been mapped as the representation of FHIR R5 element Task.doNotPerform: http://hl7.org/fhir/StructureDefinition/request-doNotPerform. The attributes provided with the Task qualify what is not to be done. For example, if a requestedPeriod is provided, the 'do not' request only applies within the specified time. If a requestedPerformer is specified then the 'do not' request only applies to performers of that type. Qualifiers include: code, subject, occurrence, requestedPerformer and performer.

    In some cases, the Request.code may pre-coordinate prohibition into the requested action. E.g. 'NPO' (nothing by mouth), 'DNR' (do not recussitate). If this happens, doNotPerform SHALL NOT be set to true. I.e. The resource shall not have double negation. (E.g. 'Do not DNR').

    doNotPerform should ONLY be used with Tasks that are tightly bounded in time or process phase. E.g. 'Do not fulfill the midnight dose of medication X tonight due to the early morning scheduled procedure, where the nurse could reasonably check off 'Med X not given at midnight as instructed'. Similarly, a decision support proposal that a patient should not be given a standard intake questionnaire (because the patient is cognitively impaired) would be marked as 'complete' or 'rejected' when the clinician preps the CarePlan or order set after reviewing the decision support results. If there is a need to create a standing order to not do something that can't be satisfied by a single 'non-action', but rather an ongoing refusal to perform the function, MedicationRequest, ServiceRequest or some other form of authorization should be used.

    Control0..1
    TypeExtension(Do not perform) (Extension Type: boolean)

      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).

      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.

This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.

            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.

            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).

            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.

Element Task.requestedPeriod has no mapping targets in FHIR R4. Typically, this is because the element has been added (is a new element). This is typically used when the Task is not seeking fulfillment of a focus Request, as in that case the period would be specified on the Request and/or in the Task.restriction.period.

                Element Task.doNotPerform has a context of Task based on following the parent source element upwards and mapping to Task. Element Task.doNotPerform has no mapping targets in FHIR R4. Typically, this is because the element has been added (is a new element). An externally-defined extension that has been mapped as the representation of FHIR R5 element Task.doNotPerform: http://hl7.org/fhir/StructureDefinition/request-doNotPerform. The attributes provided with the Task qualify what is not to be done. For example, if a requestedPeriod is provided, the 'do not' request only applies within the specified time. If a requestedPerformer is specified then the 'do not' request only applies to performers of that type. Qualifiers include: code, subject, occurrence, requestedPerformer and performer.

                In some cases, the Request.code may pre-coordinate prohibition into the requested action. E.g. 'NPO' (nothing by mouth), 'DNR' (do not recussitate). If this happens, doNotPerform SHALL NOT be set to true. I.e. The resource shall not have double negation. (E.g. 'Do not DNR').

                doNotPerform should ONLY be used with Tasks that are tightly bounded in time or process phase. E.g. 'Do not fulfill the midnight dose of medication X tonight due to the early morning scheduled procedure, where the nurse could reasonably check off 'Med X not given at midnight as instructed'. Similarly, a decision support proposal that a patient should not be given a standard intake questionnaire (because the patient is cognitively impaired) would be marked as 'complete' or 'rejected' when the clinician preps the CarePlan or order set after reviewing the decision support results. If there is a need to create a standing order to not do something that can't be satisfied by a single 'non-action', but rather an ongoing refusal to perform the function, MedicationRequest, ServiceRequest or some other form of authorization should be used.

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.
