0. Observation
Definition | 對病人、設備或其他對象進行的測量和簡單判定。 Measurements and simple assertions made about a patient, device or other subject.
Short | 檢驗檢查，測量及簡單的判定。Measurements and simple assertions
Comments | Used for simple observations such as device measurements, laboratory atomic results, vital signs, height, weight, smoking status, comments, etc. Other resources are used to provide context for observations such as laboratory reports, etc.

Summary | false
Alternate Names | Vital Signs, Measurement, Results, Tests
Invariants | dom-2: If the resource is contained in another resource, it SHALL NOT contain nested Resources (contained.contained.empty()) dom-3: If the resource is contained in another resource, it SHALL be referred to from elsewhere in the resource or SHALL refer to the containing resource (contained.where((('#'+id in (%resource.descendants().reference | %resource.descendants().as(canonical) | %resource.descendants().as(uri) | %resource.descendants().as(url))) or descendants().where(reference = '#').exists() or descendants().where(as(canonical) = '#').exists() or descendants().where(as(canonical) = '#').exists()).not()).trace('unmatched', id).empty()) dom-4: If a resource is contained in another resource, it SHALL NOT have a meta.versionId or a meta.lastUpdated (contained.meta.versionId.empty() and contained.meta.lastUpdated.empty()) dom-5: If a resource is contained in another resource, it SHALL NOT have a security label (contained.meta.security.empty()) dom-6: A resource should have narrative for robust management (text.`div`.exists()) obs-6: dataAbsentReason SHALL only be present if Observation.value[x] is not present (`dataAbsentReason.empty() or value.empty()`) obs-7: If Observation.code is the same as an Observation.component.code then the value element associated with the code SHALL NOT be present (`value.empty() or component.code.where(coding.intersect(%resource.code.coding).exists()).empty()`) vs-2: If there is no component or hasMember element then either a value[x] or a data absent reason must be present. (`(component.empty() and hasMember.empty()) implies (dataAbsentReason.exists() or value.exists())`) obs-6: dataAbsentReason SHALL only be present if Observation.value[x] is not present (dataAbsentReason.empty() or value.empty()) obs-7: If Observation.code is the same as an Observation.component.code then the value element associated with the code SHALL NOT be present (value.empty() or component.code.where(coding.intersect(%resource.code.coding).exists()).empty())
2. Observation.implicitRules
Definition | 構建resource時遵循的一系列規則的參照，在處理內容時必須理解這些規則。通常這是對IG所定義之特殊規則及其他profiles的參照。 A reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc.
Short | 創建此內容所依據的一組規則A set of rules under which this content was created
Comments | 宣告這套規則限制了內容只能被有限的交易夥伴所理解。這從本質上限制了資料的長期有用性。然而，現有的健康生態體系高度分裂，還沒有準備好以普遍可計算的方式定義、收集和交換資料。只要有可能，實作者和/或規範編寫者應該避免使用這個資料項目。通常在使用時，此URL是對IG的參照，此IG將這些特殊規則與其他profiles、value sets等一起定義為其敘述的一部分。 Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element. Often, when used, the URL is a reference to an implementation guide that defines these special rules as part of it's narrative along with other profiles, value sets, etc.
Control | 0..1
Type | uri
Is Modifier | true because This element is labeled as a modifier because the implicit rules may provide additional knowledge about the resource that modifies it's meaning or interpretation
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Summary | true
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
4. Observation.modifierExtension
Definition | May be used to represent additional information that is not part of the basic definition of the resource and that modifies the understanding of the element that contains it and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. 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 is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions. Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).
Short | Extensions that cannot be ignored
Comments | 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.
Control | 0..*
Type | Extension
Is Modifier | true because Modifier extensions are expected to modify the meaning or interpretation of the resource that contains them
Summary | false
Requirements | Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions. Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.

Definition | 結果值的狀態 The status of the result value.
Short | registered ｜ preliminary ｜ final ｜ amended +registered | preliminary | final | amended +
Comments | 這個資料項目被標記為修飾語／修飾用，因為附加到其他文件上的文件，其本身是不完整的文件。 This element is labeled as a modifier because the status contains codes that mark the resource as not currently valid.

Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
8. Observation.category
Definition | 可以正式參照一個專門術語或本體論來定義一個概念，或者也可以文字表述此概念。 A code that classifies the general type of observation being made.
Short | 概念（concept）－參照一個專門術語或只是純文字。Classification of type of observation
Comments | 並非所有的專門術語使用都符合這個一般模式。在某些情況下，資料模型不應該使用CodeableConcept而應直接使用Coding，並提供他們自己的結構來管理text、codings、translation、資料項目之間的關係、以及先組合配對／前組合式（pre-coordination）和後組合配對／後組合式（post-coordination）。 In addition to the required category valueset, this element allows various categorization schemes based on the owner’s definition of the category and effectively multiple categories can be used at once.

Comments | 人們期望這個資料項目的cardinality為1...1。唯一可能缺少對象的情況是當檢驗檢查是由一個不認識病人的設備進行的。在這種情況下，應透過一些情境／通道對應（context／channel matching）技術將檢驗檢查與病人對應，此時，應更新檢驗檢查資訊。 One would expect this element to be a cardinality of 1..1. The only circumstance in which the subject can be missing is when the observation is made by a device that does not know the patient. In this case, the observation SHALL be matched to a patient through some context/channel matching technique, and at this point, the observation should be updated.

32. Observation.effective[x]
Definition | 宣告檢驗檢查值的產出時間或時間區段是真的。對於生物學研究對象—例如病人—這通常被稱為「生理相關時間」。這通常是處置的時間或採樣的時間，但很多時候不知道日期或時間的來源，只知道日期或時間本身。 The time or time-period the observed value is asserted as being true. For biological subjects - e.g. human patients - this is usually called the "physiologically relevant time". This is usually either the time of the procedure or of specimen collection, but very often the source of the date/time is not known, only the date/time itself.
Short | 檢驗檢查執行日期或時間區間Clinically relevant time/time-period for observation
Comments | 除非這是一份檢驗檢查的歷史報告，否則至少應該有一個日期。為了記錄不精確或「模煳」的時間（例如：測量「早餐後 」血糖），使用Timing datatype以允許測量能與常規生活事件連結。 At least a date should be present unless this observation is a historical report. For recording imprecise or "fuzzy" times (For example, a blood glucose measurement taken "after breakfast") use the Timing datatype which allow the measurement to be tied to regular life events.

Short | 缺少檢驗檢查結果的原因Why the result is missing
Comments | 空值（Null）或例外值可以在FHIR Observations中以兩種方式表示，一種方法是簡單地將它們含括在值集中，並在值中表示例外。例如：血清檢測的測量值可以是「檢測到」、「未檢測到」、「不確定」或「檢測未完成」。 另一種方法是使用資料項目value呈現實際檢驗檢查值，並使用資料項目dataAbsentReason來明確記錄例外值。例如：當測量沒有完成，可使用dataAbsentReason代碼「error」。請注意，只有在有值的情況下，才可以報告檢驗檢查。例如：只有在>0的情況下才可能報告細胞計數的差值。由於有這些選項，所以需要有使用案例協議（use-case agreements）來解釋一般檢驗檢查的例外值。 Null or exceptional values can be represented two ways in FHIR Observations. One way is to simply include them in the value set and represent the exceptions in the value. For example, measurement values for a serology test could be "detected", "not detected", "inconclusive", or "specimen unsatisfactory". The alternate way is to use the value element for actual observations and use the explicit dataAbsentReason element to record exceptional values. For example, the dataAbsentReason code "error" could be used when the measurement was not completed. Note that an observation may only be reported if there are values to report. For example differential cell counts values may be reported only when > 0. Because of these options, use-case agreements are required to interpret general observations for null or exceptional values.

52. Observation.component
Definition | 有有些檢驗檢查有多個組成之檢驗檢查，這些組成之檢驗檢查被表達為具有相同屬性的獨立的代碼值對（code value pair）。例子包括血壓測量的收縮壓和舒張壓即為組成之檢驗檢查（component observations），以及遺傳學檢驗檢查的多個組成之檢驗檢查。 Some observations have multiple component observations. These component observations are expressed as separate code value pairs that share the same attributes. Examples include systolic and diastolic component observations for blood pressure measurement and multiple component observations for genetics observations.

However, the reference range for the primary observation value is not inherited by the component values and is required when appropriate for each component observation.

54. Observation.component.modifierExtension
Definition | May be used to represent additional information that is not part of the basic definition of the element and that modifies the understanding of the element in which it is contained and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. 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. Applications processing a resource are required to check for modifier extensions. Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).
Short | Extensions that cannot be ignored even if unrecognized
Comments | 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.
