Examples
Description
This profile represents the constraints applied to the Observation resource by the PS-CA project to represent Alcohol use assessment in a patient summary. It allows for cross-border and cross-jurisdiction sharing of Social History Information.

<comment value="This is a fixed pattern that enforces the presence of a globally shared code to represent this concept. It is meant to mimic the approach used in a number of FHIR implementation guides to constrain alcohol use observations, however minimal existing alcohol use observation profiles exist - so this code may change if other terminology is identified. Additional codings can be supplied, but at least one of them must follow the pattern below." />

Key Differences between the IPS-UV and PS-CA
Must Support Differences:
PS-CA has added a Must Support (MS) flag to the following elements, which are not MS in the IPS-UV specification:
Observation.statusObservation.value[x]andObservation.value[x]:valueQuantity
Cardinality Differences:
There are no cardinality differences between this profile and IPS-UV
Vocabulary Differences:
There are no vocabulary differences between this profile and IPS-UV
Other differences between the IPS and PS-CA Include:
- Data type profiles (e.g., CodeableConcept) and reference targets (e.g., Patient) replaced with PS-CA equivalents when appropriate
Observation.code: IPS datatype profiling removed- extension slicing corrected
