The Fallback Library contains a rule that ensures creation of a Task that draws attention to a measurement needing evaluation. It is intended for implicit use in case no other automated processing type Library has been set up for a given ProcedureRequest ServiceRequest through its ActivityDefinition.

...

This Library contains a generic rule that performs assessment of an Observation based on absolute reference range(s) automatically copied from a ProcedureRequest ServiceRequest referencing an ActivityDefinition that references the Library. The rule in this Library is automatically performed as a reaction to submitting of the Observation. This Library can be referenced from an ActivityDefinition along with other Library, even the Relative Reference Ranges Library described below.

The input Observation must have

It is not necessary to provide the ProcedureRequest ServiceRequest as input. The Libary$evaluate operation will retrieve it by resolving the basedOn reference in the Observation.

Output will be a code from the http://hl7.org/fhir/v3/ObservationInterpretation CodeSystem:

Output Coding

Evaluation

code=IND, system=http://hl7.org/fhir/v3/ObservationInterpretation, display=Indeterminate

The referenced

ProcedureRequest

ServiceRequest does not contain ehealth-reuseCriteria specifying a max age of the height Observation. This max age, although stated for reuse, is used for the height Observation use in an BMI calculation also.

code=N, system=http://hl7.org/fhir/v3/ObservationInterpretation, display=Normal

The height Observation has not exceeded the max age specified in ehealth-reuseCriteria in the referenced

ProcedureRequest

ServiceRequest.

code=L, system=http://hl7.org/fhir/v3/ObservationInterpretation, display=Low

The height Observation has exceeded the max age specified in ehealth-reuseCriteria in the referenced

ProcedureRequest
