This structure is derived from Observation

Name	Card.	Type	Constraints and Usage
Observation	0..*	Observation	obs-6: dataAbsentReason SHALL only be present if Observation.value[x] is not present obs-7: Component code SHALL not be same as observation code Definition: Measurements and simple assertions made about a patient, device or other subject. Comments: At present, only supported observations are height and weight.
id	1..1	id	Definition: The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes. Comments: Usage Note: This will usually be a GUID and is assigned by the sending application. Ideally it should be consistent for all messages referencing this observation measurement.
status	1..1	code	Binding: ObservationStatus (required): Codes providing the status of an observation. Fixed Value: final Definition: The status of the result value. Comments: Fixed value: final
category	1..1	Shared Health CodeableConcept Code	Binding: Observation Category Codes (example): Codes for high level observation categories . Definition: A concept that may be defined by a formal reference to a terminology or ontology or may be provided by text. Comments: codes are from HL7 and system URL is http://hl7.org/fhir/observation-category.
coding	1..*	Coding	Slice: Unordered, Open by value:system Definition: A reference to a code defined by a terminology system. Comments: Codes may be defined very casually in enumerations, or code lists, up to very formal definitions such as SNOMED CT - see the HL7 v3 Core Principles for more information. Ordering of codings is undefined and SHALL NOT be used to infer meaning. Generally, at most only one of the coding values will be labelled as UserSelected = true.
system	1..1	uri	Definition: The identification of the code system that defines the meaning of the symbol in the code. Comments: This is the URI that represents the coding system as defined within the binding.
code	1..1	code	Definition: A symbol in syntax defined by the system. The symbol may be a predefined code or an expression in a syntax defined by the coding system (e.g. post-coordination). Comments: This is the code as defined within the binding.
coding (HL7Code)	1..*	Coding	Definition: A reference to a code defined by a terminology system. Comments: See children for fixed value
system	1..1	uri	Fixed Value: http://hl7.org/fhir/observation-category Definition: The identification of the code system that defines the meaning of the symbol in the code. Comments: Fixed value: http://hl7.org/fhir/observation-category

code	1..1	Shared Health CodeableConcept Code	Binding: PrescriptionObservationTypeVitalSign (20170626) (required): Pharmacy-related vital signs Definition: Identification of the type of measurement/observation that was made about the patient. The only two allowable types are height and weight. Comments:
coding	1..*	Coding	Definition: A reference to a code defined by a terminology system. Comments: Code and System will be set. For Body height code value = 8302-2 For Body weight code value = 29463-7
system	1..1	uri	Definition: The identification of the code system that defines the meaning of the symbol in the code. Comments: This is the URI that represents the coding system as defined within the binding.
code	1..1	code	Definition: A symbol in syntax defined by the system. The symbol may be a predefined code or an expression in a syntax defined by the coding system (e.g. post-coordination). Comments: This is the code as defined within the binding.
subject	1..1	Reference(Shared Health Patient) {b }	Definition: A reference from one resource to another. Comments: This must point to the patient associated with the message
effective[x] (effectiveDateTime)	0..1	dateTime	Definition: When the measurement was made Comments: Conformance Rule: Observations of height and weight must be sent when there is an effective date.
value[x] (valueQuantity)	1..1	Shared Health Quantity	qty-3: If a code for the unit is present, the system SHALL also be present Definition: A measured amount (or an amount that can potentially be measured). Note that measured amounts include amounts that are not precisely quantified, including amounts involving arbitrary units and floating currencies. Comments: Conformance Rule: This MUST be expressed in kilograms (weight), and centimeters (height). Value, System and Code will be set. For Body height; value - set to height measurement in centimeters system = http://unitsofmeasure.org code = cm For Body weight: value - set to weight measurement in kilograms system = http://unitsofmeasure.org code = kg
