Maintaining a Reference Base for Relative Reference Ranges

Certain use of relative reference ranges involves an automated processing type of Library (see https://ehealth-dk.atlassian.net/wiki/spaces/EDTW/pages/1251409937/Library+Resources#Assessment-of-Relative-Reference-Ranges-Library-and-Rule ) which compares a submitted measurement against a reference base.

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

• 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), a number of Goal should be made with respective target.measure matching the components (e.g. systolic and diastolic blood pressure for blood pressure).

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