The reference base is captured in a FHIR Goal with the following characteristics:

• description is Coding for reference-value (see https://docs.ehealth.sundhed.dk/latest-released/ig/ValueSet-ehealth-goal-description.html)

• lifeCycleStatus is accepted

• start has a startDate

• target.measure is an observation code in the ValueSet goal-target-measure similar to that of the corresponding ActivityDefinition

  • For an ActivityDefinition with code being a Coding of Blood Pressure (or other composite measurement), the Goal should contain a number of Goal should be made target, each with respective target.measure matching a component of the components composite measurement (e.g. systolic and diastolic blood pressure for blood pressure).

• target.detailQuantity contains the actual reference base value (and unit). The reference base value can be

• addresses is a reference to the ServiceRequest where the relative reference range is maintained.

The Goal shall be added to CarePlan.goal in the CarePlan referencing the ServiceRequest the relative reference range is maintained. As time goes, additional Goal that supersedes previous Goal can be added. This approach shall be used instead of simply adjusting the reference base value of an existing Goal.

The Library described in https://ehealth-dk.atlassian.net/wiki/spaces/EDTW/pages/1251409937/Library+Resources#Assessment-of-Relative-Reference-Ranges-Library-and-Rule favors the FHIR Goal with most recent start.startDate.
