Elements
| Name | Required | Type | Description |
|---|---|---|---|
| id | string | Unique id for inter-element referencing | |
| Details | |||
| Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces. | |||
| extension | Extension[] | Additional content defined by implementations | |
| Details | |||
| May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. | |||
| There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone. | |||
| value | decimal | Numerical value (with implicit precision) | |
| Details | |||
| The value of the measured amount. The value includes an implicit precision in the presentation of the value. | |||
| 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). | |||
| comparator | code | < | |
| Details | |||
| How the value should be understood and represented - whether the actual value is greater or less than the stated value due to measurement issues; e.g. if the comparator is "<" , then the real value is < stated value. | |||
| unit | string | Unit representation | |
| Details | |||
| A human-readable form of the unit. | |||
| system | uri | System that defines coded unit form | |
| Details | |||
| The identification of the system that provides the coded form of the unit. | |||
| code | code | Coded form of the unit | |
| Details | |||
| A computer processable form of the unit in some unit representation system. | |||
| The preferred system is UCUM, but SNOMED CT can also be used (for customary units) or ISO 4217 for currency. The context of use may additionally require a code from a particular system. |
