| Name | Card. | Type | Constraints and Usage |
|---|---|---|---|
 Quantity | 0..* | qty-3: If a code for the unit is present, the system SHALL also be present sqty-1: The comparator is not used on a SimpleQuantity Definition: A measured or counted amount of a medication expressed as a value and human-readable string with optional coded units expressed in a local coding system Comments: Usage Note: Quantity is used throughout the messages. It may be a drug form (e.g. TAB) an administrable drug (e.g. PUFF) form or a unit of measure (e.g. mg). | |
 value | 1..1 | decimal | Definition: The value of the measured amount. The value includes an implicit precision in the presentation of the value. Comments: The implicit precision in the value should always be honored. Monetary values have their own rules for handling precision (refer to standard accounting text books). |
| unit | 1..1 | string | Definition: A human-readable form of the unit. Comments: Usage Note: This must be used to convey the english display that is associated with the code. (Note: Rationale for change: to accommodate fax template) |
| system | 0..1 | uri | Definition: The identification of the system that provides the coded form of the unit. |
 code | 0..1 | code | Binding: PrescribedQuantityUnit (extensible) Definition: A computer processable form of the unit in some unit representation system. Comments: Conformance Rule: A Code must be supplied if one is available from the PrescribedQuantityUnit subset. If the user picks a prescribed quantity unit that does not have a code in the PrescribedQuantityUnit subset, only then can unit be supplied without a code. If a receiving system receives a code that it doesn't recognize, the system must just display the unit. |
