U.S. Data Access Framework (DAF) Vital Signs Profile vs QICore-Observation

Messages

A series of messages from the comparison algorithm. Errors indicate that solutions cannot be interoperable across both implementation guides (or that there are structural flaws in the definition of at least one).

Warnings about the comparison
Observation.referenceRange.lowStructureDefinition U.S. Data Access Framework (DAF) Vital Signs Profile has a constraint that is not found in QICore-Observation and it is uncertain whether they are compatible (not(exists(f:code)) or exists(f:system))
Observation.referenceRange.lowStructureDefinition U.S. Data Access Framework (DAF) Vital Signs Profile has a constraint that is not found in QICore-Observation and it is uncertain whether they are compatible (not(exists(f:comparator)))

Notes about differences (e.g. definitions)
Observation.codeElements differ in definition for short:
"Coded Responses from C-CDA Vital Sign Results"
"Type of observation (code / type)"
Observation.codeElements differ in definition for definition:
"Coded Responses from C-CDA Vital Sign Results."
"Describes what was observed. Sometimes this is called the observation "name"."
Observation.codeElements differ in definition for requirements:
"5. SHALL contain exactly one [1..1] code, where the @code SHOULD be selected from ValueSet HITSP Vital Sign Result Type 2.16.840.1.113883.3.88.12.80.62 DYNAMIC (CONF:7301)."
"Knowing what kind of observation is being made is essential to understanding the observation."
Observation.codeElements differ in definition for binding.description:
"This identifies the vital sign result type."
"LOINC codes"
Observation.effective[x]Elements differ in definition for short:
"Often just a dateTime for Vital Signs"
"Clinically relevant time/time-period for observation"
Observation.effective[x]Elements differ in definition for definition:
"Often just a dateTime for Vital Signs."
"The time or time-period the observed value is asserted as being true. For biological subjects - e.g. human patients - this is usually called the "physiologically relevant time". This is usually either the time of the procedure or of specimen collection, but very often the source of the date/time is not known, only the date/time itself."
Observation.value[x]Elements differ in definition for short:
"Vital Sign Value recorded with UCUM"
"Actual result"
Observation.value[x]Elements differ in definition for definition:
"Vital Sign Value recorded with UCUM."
"The information determined as a result of making the observation, if the information has a simple value."
Observation.value[x]Elements differ in definition for requirements:
"9. SHALL contain exactly one [1..1] value with @xsi:type="PQ" (CONF:7305)."
"An observation exists to have a value, though it may not if it is in error, or it represents a group of observations."
Observation.value[x]Elements differ in definition for binding.description:
"Common UCUM units for recording Vital Signs"
"SNOMED CT for coded results"
Observation.value[x].codeElements differ in definition for short:
"Coded responses from the common UCUM units for vital signs value set."
"Coded form of the unit"
Observation.value[x].codeElements differ in definition for definition:
"Coded responses from the common UCUM units for vital signs value set."
"A computer processable form of the unit in some unit representation system."
Observation.referenceRange.lowElements differ in definition for short:
"A fixed quantity (no comparator)"
"Low Range, if relevant"
Observation.referenceRange.lowElements differ in definition for definition:
"The comparator is not used on a SimpleQuantity"
"The value of the low bound of the reference range. The low bound of the reference range endpoint is inclusive of the value (e.g. reference range is >=5 - <=9). If the low bound is omitted, it is assumed to be meaningless (e.g. reference range is <=2.3)."
Observation.referenceRange.highElements differ in definition for short:
"A fixed quantity (no comparator)"
"High Range, if relevant"
Observation.referenceRange.highElements differ in definition for definition:
"The comparator is not used on a SimpleQuantity"
"The value of the high bound of the reference range. The high bound of the reference range endpoint is inclusive of the value (e.g. reference range is >=5 - <=9). If the high bound is omitted, it is assumed to be meaningless (e.g. reference range is >= 2.3)."
Observation.relatedElements differ in definition for short:
"Used when reporting systolic and diastolic blood pressure."
"Resource related to this observation"
Observation.relatedElements differ in definition for definition:
"Used when reporting systolic and diastolic blood pressure."
"A reference to another resource (usually another Observation but could also be a QuestionnaireAnswer) whose relationship is defined by the relationship type code."

Intersection

The intersection of the 2 constraint statements. This is what resource authors (either client or server) would need to conform to produce content valid against both implementation guides.
