Count

Base StructureDefinition for Count Type: 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.

Properties

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	< | <= | >= | > - how to understand the value 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.
