11.29.0 SubstanceAmount

Pharmacy

Work Group

Maturity Level: 3

Standards Status: Trial Use

This type is still undergoing development and review by the appropriate Workgroups. At this time, is considered only as a draft design not suitable for production implementation

The SubstanceAmount structure defines TODO.

Note: the SubstanceAmount structure allows modifier extensions.

Structure

Name	Flags	Card.	Type	Description & Constraints
SubstanceAmount	Σ D		Element	Chemical substances are a single substance type whose primary defining element is the molecular structure. Chemical substances shall be defined on the basis of their complete covalent molecular structure; the presence of a salt (counter-ion) and/or solvates (water, alcohols) is also captured. Purity, grade, physical form or particle size are not taken into account in the definition of a chemical substance or in the assignment of a Substance ID Elements defined in Ancestors: id, extension, modifierExtension
amount[x]	Σ	0..1		Used to capture quantitative values for a variety of elements. If only limits are given, the arithmetic mean would be the average. If only a single definite value for a given element is given, it would be captured in this field
amountQuantity			Quantity
amountRange			Range
amountString			string
amountType	Σ	0..1	CodeableConcept	Most elements that require a quantitative value will also have a field called amount type. Amount type should always be specified because the actual value of the amount is often dependent on it. EXAMPLE: In capturing the actual relative amounts of substances or molecular fragments it is essential to indicate whether the amount refers to a mole ratio or weight ratio. For any given element an effort should be made to use same the amount type for all related definitional elements
amountText	Σ	0..1	string	A textual comment on a numeric value
referenceRange	Σ	0..1	Element	Reference range of possible or expected values
lowLimit	Σ	0..1	Quantity	Lower limit possible or expected
highLimit	Σ	0..1	Quantity	Upper limit possible or expected
