This page list all the queries that Child Health Project team wants to discuss with CWG and decide a path forward.
Date and Decision
At this moment NCDHC uses only a handful of elements from the default FHIR profiles. This gives an option to the implementer to supply more data than originally supported by NCDHC. We want to decide whether we should restrict the data set or leave as it is with some control.
I think we have two options on this:
Option 1: Remove all non-supported elements from the profile. This may introduce strict boundary on the profile and loose re-usability.
Option 2: Use must support flag to indicate what is supported by NCDHC. If the source system supplies more data, then NCDHC will not remove them but will not process them or take any ownership of that additional data. They will remain as-is in the supplied resources.
Date and Decision
Shall we make effective[x] as mandatory in the profile when there any value[X] provided?
in what situation effective[x] can not be provided (other than historical observations which we are not dealing with in NCDHC)?
Add Invariant to check the existence of effective[x] if the absentReason is not provided
Use of component or hasMember along with dataAbsentReason
Do not allow dataAbsentReason along with component and/or hasMember in the same Observation instance.
Use closed slice vs open slice in coding
NCDHC recommends to use closed slice to avoid ambiguous codes in the instance
What is recommended to use for Observation.category
NCDHC to use ‘procedure’ or ‘exam’ as category (as applicable)
There are some Observation profiles under NCDHC which points to http://build.fhir.org/ig/hl7au/au-fhir-childhealth/ValueSet-ncdhc-observation-completion-status-1.html just to record if the Procedure was performed or not.
The main objective of these types of Observations are to capture the Observation.interpretation and comments (if any)
The ValueSet includes the following values:
443938003 - Procedure carried out on subject
416237000 - Procedure not done
439495000 - Counselling declined
Proposal: Remove this valueset and implement the following changes
Observation.value[x] make it valueBoolean to allow true/false
move “Procedure not done” and “Counselling declined” as part of Observation.dataAbsentReason
Use of au-practitionerrole to record “Examiner” in Observation instead of current implementation where we are usingau-practitioner
Use of au-practitionerrole to record “Examiner” in Observation. This provide the option to record the Examiner and associated Organisation along with practitioner's role.
