[Immunization] How to define tasks dependencies | Content Changes

[dubdabasoduba]

Implementation

• The Tasks resource has a Task.input attribute that is used to define the information required for the task to be
  performed. Use this attribute to define the dependencies.

Dependent Administration timing constraints

• Define time constraints for the dependencies here. This object will hold a code on the Task.input.type attribute and
  a period on the Task.input.value attribute.
  • Here is an
    example {"type":{"coding":[{"system":"http://snomed.info/sct","code":"371154000","display":"Dependent (qualifier value)"}]},"value":28}

Dependency definition

• Use the Task partOf attribute to declare the prerequisites by adding a reference to the prerequisite.
  • Here is an example {"reference":"Task/<string-uuid>"}
• The partOf attribute can be used for mapping other items therefore the following combination is needed for it to be
  interpreted as a prerequisite reference.
  • The dependent task should have a Task.input.type attribute defined with
    the {"coding":[{"system":"http://snomed.info/sct","code":"900000000000457003","display":"Reference set attribute (foundation metadata concept)"}]}
  • The Task should also have the prerequisite tasks referenced on the Task.input attribute with the reference code
    on the Task.input.type attribute and the prerequisite on the Task.input.value attribute.
    • Here is an
      example {"type":{"coding":[{"system":"http://snomed.info/sct","code":"900000000000457003","display":"Reference set attribute (foundation metadata concept)"}]},"value":{"reference":"Task/<string-uuid>"}}

Task grouping definitions

• Update the Task.groupIdentifier to add the Task grouping.
  • Here is an example {"groupIdentifier":{"use":"secondary","value":"immunizations_at_birth"}}
    or {"groupIdentifier":{"use":"secondary","value":"immunization_at_6_weeks"}}
  • Use the Task.groupIdentifier to group the Tasks in the upcoming encounters and the profile screens.

Assumptions

• This time constraint will always be defined in days.
