Summary

Mandatory: 7 elements
Must-Support: 9 elements

Structures

This structure refers to these other structures:

• Patient - Kisumu Patient (http://fhir.kisumuhealth.co.ke/StructureDefinition/ksm-patient)
• Encounter - Kisumu Patient (http://fhir.kisumuhealth.co.ke/StructureDefinition/ksm-patient-encounter)

Slices

This structure defines the following Slices:

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

This structure is derived from Observation

Summary

Mandatory: 7 elements
Must-Support: 9 elements

Structures

This structure refers to these other structures:

• Patient - Kisumu Patient (http://fhir.kisumuhealth.co.ke/StructureDefinition/ksm-patient)
• Encounter - Kisumu Patient (http://fhir.kisumuhealth.co.ke/StructureDefinition/ksm-patient-encounter)

Slices

This structure defines the following Slices:

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