Obligations

Obligations are a new (and evolving) mechanism in FHIR to provide a consistent and machine processable way for profiles to define their expectations for system behaviors.

This profile utilizes the Obligation Extension to convey these expectations.

Note: Simplifier is working on rendering of Obligations. In the meantime the Obligations applied on the profile (see JSON & XML structure) have been rendered as a table below for easier viewing.

Obligation Code Actor Elements
SHALL:able-to-populate Server Actor (CA Core) code, status, form, amount, .ingredient.item[x]:itemCodeableConcept, .ingredient.strength
SHALL:no-error Client Actor (CA Core) code, status, form, amount, .ingredient.item[x]:itemCodeableConcept, .ingredient.strength

Terminology

This version of the guide is based on the early content development of the pan-Canadian Health Data Content Framework (pCHDCF). The pCHDCF is beginning to introduce recommended terminology for select concepts. Implementers should be aware that the identification of preferred terminology continues to progress and that some coded elements may have terminology recommendations added in future releases.

Note: Implementers should be aware of the limitations in some terminology referenced in this guide that is not fully expressed as an enumerated FHIR ValueSet or resolvable FHIR CodeSystems. Readers should refer to the Known Issues & Future Development page.

Bindings

Primary bindings are expressed in the rendering of the profile above (as well as can be found in the JSON/XML file).

Additional terminology bindings are also expressed in this profile to surface Alternate Value Sets expressed in the pCHDCF Data Content Standard. Currently, Simplifier does not render the additionalBinding extension that is applied within the profile to express these Alternate Value Sets. See Known Issues & Future Development page.

In the interim, the terminology that has been expressed as additionalBindings is rendered below for ease of use:

Mappings to pCHDCF

Draft Data Content Standard Element (As of 2024-02-15) Draft Data Content Standard Element Definition (As of 2024-02-15) FHIR Profile Element Additional Notes
Medication Code The code (e.g., DIN) of the medication that was administered or was to be administered. Medication.code
Medication Status A code to indicate if the medication is in active use. Medication.status
Medication Form The physical form (e.g., liquid, tablet) of a dose of the medication. Medication.form
Medication Amount The specific amount of the drug in the packaged product, when specifying a product that has the same strength. Medication.amount
Medication Active Ingredient A list of Substance that alone or in combination with one or more other ingredients produces the intended activity of a medicinal product. Medication.ingredient.item[x]:itemCodeableConcept
Medication Strength The potency of the drug/chemical, usually measured in metric weight and described as the strength of the product’s active (medicinal) ingredient. Medication.ingredient.strength Explicit mappings to value and units can be found in the Drug Quantity Profile
Medication Strength Unit of Measure The units of measure for the medication prescribed strength number. Quantity.system + Quantity.code To fully provide meaning to unit of measure under this definition (which has an expected CodeableConcept data type), the system and code sub-elements must be used together
