Resource Profile: Rheumatic Fever Diagnosis Group

This profile constrains the codes valid on an Observation so it can represent groups of rheumatic fever diagnosis data.

Constraints coding of a standard FHIR Observation for use in RF diagnosis representation

Usage:

• Refer to this Resource Profile: Rheumatic Fever Condition
• Examples for this Resource Profile: Observation/DiagnosisDetail-ECHO, Observation/DiagnosisDetail-JonesCriteria, Observation/DiagnosisDetail-StrepEvidence-Secondary and Observation/DiagnosisDetail-StrepEvidence
