Resource Profile: Conceptual Cohort Definition Outcome

Official URL: http://fhir.awmf.org/awmf.ig/StructureDefinition/conceptual-cohort-definition-outcome Version: 0.2.0
Draft as of 2026-01-29 Computable Name: ConceptualCohortDefinitionOutcome

A structured definition of the outcome as defined for a PICO question.

Guidance

This profile represents a Conceptual Cohort Definition for Outcome – a structured definition of the outcome (the "O" in PICO) as defined for a clinical question.

Overview

The outcome definition describes what clinical endpoints or results are being measured, such as mortality, morbidity, quality of life, adverse events, or other patient-relevant outcomes.

Key Elements

Code (Fixed)

The code element identifies this as an outcome definition:

* code = $cs-pico#outcome

Usage in PICO Questions

Multiple outcomes can be defined for a single PICO question. This profile is referenced from the PICO Question profile:

// In PICOQuestion:
* characteristic[outcome][+]
  * code = $cs-pico#outcome
  * valueReference = Reference(MortalityOutcome)
* characteristic[outcome][+]
  * code = $cs-pico#outcome
  * valueReference = Reference(QualityOfLifeOutcome)

Relationship to Evidence Assessment

Outcome definitions are also referenced by Evidence Overall Quality Assessment profiles when assessing the evidence for specific outcomes.

Example Usage

Instance: AllCauseMortalityOutcome
InstanceOf: conceptual-cohort-definition-outcome
Usage: #example
* code = $cs-pico#outcome
* characteristic[+]
  * code.text = "All-cause mortality"
  * valueBoolean = true

This profile of a FHIR Group is derived from the conceptual-cohort-definition FHIR resource.
