Structures

This structure refers to these other structures:

• Patient Profile - NEIR (http://nhin.example.ng/StructureDefinition/neir-patient)

Slices

This structure defines the following Slices:

• The element 1 is sliced based on the value of Observation.component
• The element 1 is sliced based on the value of Observation.component.value[x]

This structure is derived from Observation

Summary

Mandatory: 15 elements
Must-Support: 3 elements

Structures

This structure refers to these other structures:

• Patient Profile - NEIR (http://nhin.example.ng/StructureDefinition/neir-patient)

Slices

This structure defines the following Slices:

• The element 1 is sliced based on the value of Observation.component
• The element 1 is sliced based on the value of Observation.component.value[x]
