Title: "Bangladesh Observation Profile"
|
|
Description: """
|
|
Base observation profile for Bangladesh. This is an abstract-style base profile
|
|
from which all BD-Core observation profiles are derived. It is not intended to
|
|
be used directly in clinical resources — use a derived profile instead.
|
|
|
|
Derived profiles (v0.4.0):
|
|
- bd-lab-panel-observation : Laboratory panel/order (hasMember pattern)
|
|
- bd-lab-result-observation : Laboratory leaf result (child of hasMember)
|
|
|
|
Planned derived profiles (v0.5.0+):
|
|
- bd-vital-signs-observation
|
|
- bd-exam-observation
