すべてのObservation（検査測定や観察事実）の共通部分のプロファイル

The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes.

The only time that a resource does not have an id is when it is being submitted to the server using a create operation.

The metadata about the resource. This is content that is maintained by the infrastructure. Changes to the content might not always be associated with version changes to the resource.

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.

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.

The base language in which the resource is written.

Language is provided to support indexing and accessibility (typically, services such as text to speech use the language tag). The html language tag in the narrative applies to the narrative. The language tag on the resource may be used to specify the language of other presentations generated from the data in the resource. Not all the content has to be in the base language. The Resource.language should not be assumed to apply to the narrative automatically. If a language is specified, it should it also be specified on the div element in the html (see rules in HTML5 for information about the relationship between xml:lang and the html lang attribute).

A human language.

A human-readable narrative that contains a summary of the resource and can be used to represent the content of the resource to a human. The narrative need not encode all the structured data, but is required to contain sufficient detail to make it "clinically safe" for a human to just read the narrative. Resource definitions may define what content should be represented in the narrative to ensure clinical safety.

Contained resources do not have narrative. Resources that are not contained SHOULD have a narrative. In some cases, a resource may only have text with little or no additional discrete data (as long as all minOccurs=1 elements are satisfied). This may be necessary for data from legacy systems where information is captured as a "text blob" or where text is additionally entered raw or narrated and encoded information is added later.

These resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, and nor can they have their own independent transaction scope.

This should never be done when the content can be identified properly, as once identification is lost, it is extremely difficult (and context dependent) to restore it again. Contained resources may have profiles and tags In their meta elements, but SHALL NOT have security labels.

A unique identifier assigned to this observation. Observationに割り当てられたユニーク（一意）の識別ID

Allows observations to be distinguished and referenced.

A plan, proposal or order that is fulfilled in whole or in part by this event. For example, a MedicationRequest may require a patient to have laboratory test performed before it is dispensed. このイベントによって全体または部分的に実施されるプラン、提案、依頼。たとえばMedicationRequest は調剤される前に臨床検査を患者に行う必要があるかもしれない。

Allows tracing of authorization for the event and tracking whether proposals/recommendations were acted upon.

A larger event of which this particular Observation is a component or step. For example, an observation as part of a procedure. この特定のObservationが別のより大きなイベントの要素あるいは一段階であるような親イベント。たとえば、一連の処置手順の一部としてのObservation。

To link an Observation to an Encounter use encounter. See the Notes below for guidance on referencing another Observation. ObservationをEncounterにencounter要素を使ってリンクする。もうひとつ別のObservationを参照することについては、以降にあるt Notes　をガイダンスとして参照のこと。

The status of the result value.　結果値のステータス。

This element is labeled as a modifier because the status contains codes that mark the resource as not currently valid. このリソースは現在有効でないというマークをするコードを含んでいるため、この要素はモディファイアー（修飾的要素）として位置づけられている。

Codes providing the status of an observation.

Need to track the status of individual results. Some results are finalized before the whole report is finalized.

A code that classifies the general type of observation being made. 実施されているobservationの一般的なタイプを分類するコード

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. The level of granularity is defined by the category concepts in the value set. 必要なカテゴリ値セットに加えて、この要素を使用すると、所有者のカテゴリの定義に基づいたさまざまなカテゴリ化スキームが可能になり、複数のカテゴリを一度に効果的に使用できる。粒度のレベルは、値セットのカテゴリの概念によって定義される。

Codes for high level observation categories.

Used for filtering what observations are retrieved and displayed.

Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

An Extension

A reference to a code defined by a terminology system.

Codes may be defined very casually in enumerations, or code lists, up to very formal definitions such as SNOMED CT - see the HL7 v3 Core Principles for more information. Ordering of codings is undefined and SHALL NOT be used to infer meaning. Generally, at most only one of the coding values will be labeled as UserSelected = true.

Allows for alternative encodings within a code system, and translations to other code systems.

A human language representation of the concept as seen/selected/uttered by the user who entered the data and/or which represents the intended meaning of the user.

Very often the text is the same as a displayName of one of the codings.

The codes from the terminologies do not always capture the correct meaning with all the nuances of the human using them, or sometimes there is no appropriate code at all. In these cases, the text is used to capture the full meaning of the source.

Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

An Extension

The identification of the code system that defines the meaning of the symbol in the code.

The URI may be an OID (urn:oid:...) or a UUID (urn:uuid:...). OIDs and UUIDs SHALL be references to the HL7 OID registry. Otherwise, the URI should come from HL7's list of FHIR defined special URIs or it should reference to some definition that establishes the system clearly and unambiguously.

Need to be unambiguous about the source of the definition of the symbol.

The version of the code system which was used when choosing this code. Note that a well-maintained code system does not need the version reported, because the meaning of codes is consistent across versions. However this cannot consistently be assured, and when the meaning is not guaranteed to be consistent, the version SHOULD be exchanged.

Where the terminology does not clearly define what string should be used to identify code system versions, the recommendation is to use the date (expressed in FHIR date format) on which that version was officially published as the version date.

A symbol in syntax defined by the system. The symbol may be a predefined code or an expression in a syntax defined by the coding system (e.g. post-coordination).

Need to refer to a particular code in the system.

A representation of the meaning of the code in the system, following the rules of the system.

Need to be able to carry a human-readable meaning of the code for readers that do not know the system.

Indicates that this coding was chosen by a user directly - e.g. off a pick list of available items (codes or displays).

Amongst a set of alternatives, a directly chosen code is the most appropriate starting point for new translations. There is some ambiguity about what exactly 'directly chosen' implies, and trading partner agreement may be needed to clarify the use of this element and its consequences more completely.

This has been identified as a clinical safety criterium - that this exact system/code pair was chosen explicitly, rather than inferred by the system based on some rules or language processing.

Describes what was observed. Sometimes this is called the observation "name".

A human language representation of the concept as seen/selected/uttered by the user who entered the data and/or which represents the intended meaning of the user.

Very often the text is the same as a displayName of one of the codings.

The codes from the terminologies do not always capture the correct meaning with all the nuances of the human using them, or sometimes there is no appropriate code at all. In these cases, the text is used to capture the full meaning of the source.

The patient, or group of patients, location, or device this observation is about and into whose record the observation is placed. If the actual focus of the observation is different from the subject (or a sample of, part, or region of the subject), the focus element or the code itself specifies the actual focus of the observation. この観察が行われた対象となる患者、または患者のグループ、場所、またはデバイス、あるいはそれらの記録。 もし観察の実際の焦点が対象（または対象のサンプル、一部、または領域）と異なる場合、 focus要素または code自体が観察の実際の焦点を指し示す。

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. この要素は1..1のcardinalityになるはずと考えられる。この要素が欠損値になる唯一の状況は、対象患者が不明なデバイスによって観察が行われるケースである。この場合、観察は何らかのコンテキスト/チャネルマッチング技術を介して患者にマッチングされる必要があり、患者にマッチングされれば、その時点で本要素を更新する必要がある。

Observations have no value if you don't know who or what they're about.

Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

An Extension

A reference to a location at which the other resource is found. The reference may be a relative reference, in which case it is relative to the service base URL, or an absolute URL that resolves to the location where the resource is found. The reference may be version specific or not. If the reference is not to a FHIR RESTful server, then it should be assumed to be version specific. Internal fragment references (start with '#') refer to contained resources.

Using absolute URLs provides a stable scalable approach suitable for a cloud/web context, while using relative/logical references provides a flexible approach suitable for use when trading across closed eco-system boundaries. Absolute URLs do not need to point to a FHIR RESTful server, though this is the preferred approach. If the URL conforms to the structure "/[type]/[id]" then it should be assumed that the reference is to a FHIR RESTful server.

The expected type of the target of the reference. If both Reference.type and Reference.reference are populated and Reference.reference is a FHIR URL, both SHALL be consistent.

The type is the Canonical URL of Resource Definition that is the type this reference refers to. References are URLs that are relative to http://hl7.org/fhir/StructureDefinition/ e.g. "Patient" is a reference to http://hl7.org/fhir/StructureDefinition/Patient. Absolute URLs are only allowed for logical models (and can only be used in references in logical models, not resources).

This element is used to indicate the type of the target of the reference. This may be used which ever of the other elements are populated (or not). In some cases, the type of the target may be determined by inspection of the reference (e.g. a RESTful URL) or by resolving the target of the reference; if both the type and a reference is provided, the reference SHALL resolve to a resource of the same type as that specified.

Aa resource (or, for logical models, the URI of the logical model).

An identifier for the target resource. This is used when there is no way to reference the other resource directly, either because the entity it represents is not available through a FHIR server, or because there is no way for the author of the resource to convert a known identifier to an actual location. There is no requirement that a Reference.identifier point to something that is actually exposed as a FHIR instance, but it SHALL point to a business concept that would be expected to be exposed as a FHIR instance, and that instance would need to be of a FHIR resource type allowed by the reference.

When an identifier is provided in place of a reference, any system processing the reference will only be able to resolve the identifier to a reference if it understands the business context in which the identifier is used. Sometimes this is global (e.g. a national identifier) but often it is not. For this reason, none of the useful mechanisms described for working with references (e.g. chaining, includes) are possible, nor should servers be expected to be able resolve the reference. Servers may accept an identifier based reference untouched, resolve it, and/or reject it - see CapabilityStatement.rest.resource.referencePolicy.

When both an identifier and a literal reference are provided, the literal reference is preferred. Applications processing the resource are allowed - but not required - to check that the identifier matches the literal reference

Applications converting a logical reference to a literal reference may choose to leave the logical reference present, or remove it.

Reference is intended to point to a structure that can potentially be expressed as a FHIR resource, though there is no need for it to exist as an actual FHIR resource instance - except in as much as an application wishes to actual find the target of the reference. The content referred to be the identifier must meet the logical constraints implied by any limitations on what resource types are permitted for the reference. For example, it would not be legitimate to send the identifier for a drug prescription if the type were Reference(Observation|DiagnosticReport). One of the use-cases for Reference.identifier is the situation where no FHIR representation exists (where the type is Reference (Any).

Plain text narrative that identifies the resource in addition to the resource reference.

This is generally not the same as the Resource.text of the referenced resource. The purpose is to identify what's being referenced, not to fully describe it.

The actual focus of an observation when it is not the patient of record representing something or someone associated with the patient such as a spouse, parent, fetus, or donor. For example, fetus observations in a mother's record. The focus of an observation could also be an existing condition, an intervention, the subject's diet, another observation of the subject, or a body structure such as tumor or implanted device. An example use case would be using the Observation resource to capture whether the mother is trained to change her child's tracheostomy tube. In this example, the child is the patient of record and the mother is the focus. 配偶者、親、胎児、ドナーなど、患者に関連する何かまたは誰かを表す記録の患者ではない場合の、観察の実際の焦点。たとえば、母親の記録にある胎児の観察。観察の焦点はまた、既存の状態、介入、対象の食事、対象の別の観察、または腫瘍または埋め込まれた装置などの体の構造であり得る。使用例はobservationリソースを使用して、母親が子供の気管切開チューブを交換するように訓練されているかどうかをキャプチャすることである。この例では、子供が記録の患者であり、母親が焦点（focus）となる。

Typically, an observation is made about the subject - a patient, or group of patients, location, or device - and the distinction between the subject and what is directly measured for an observation is specified in the observation code itself ( e.g., "Blood Glucose") and does not need to be represented separately using this element. Use specimen if a reference to a specimen is required. If a code is required instead of a resource use either bodysite for bodysites or the standard extension focusCode. 通常、observationは対象（患者、または患者のグループ、場所、またはデバイス）について行われ、対象とobservationのために直接測定されるものとの区別は、observationコード自体（例：「血糖値」 ）で記述され、この要素を使用して個別に表す必要はない。検体（標本）への参照が必要な場合は、 specimen要素を使用する。リソースの代わりにコードが必要な場合は、人体部位にはbodysite要素を使用するか、標準の拡張機能[focusCode]（extension-observation-focuscode.html）を使用する。

The healthcare event (e.g. a patient and healthcare provider interaction) during which this observation is made. このobservationが行われるヘルスケアイベント（患者とヘルスケアプロバイダの相互作用など）（受診、入院など）。

This will typically be the encounter the event occurred within, but some events may be initiated prior to or after the official completion of an encounter but still be tied to the context of the encounter (e.g. pre-admission laboratory tests). 通常、イベントが発生したEncounterであるが、一部のイベントは、エンEncounterの正式な完了の前または後に開始される場合があり、その場合でもEncounterのコンテキストに関連付けられている（例：入院前の臨床検査）。

For some observations it may be important to know the link between an observation and a particular encounter.

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. 観測値が関連する時間または期間。レポートの対象が患者である場合、これは通常、処置や検体採取の時刻のいずれかであるが、日付/時刻の出処は不明であり、日付/時刻自体のみのことがある。

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. この観察結果が過去の報告でない限り、少なくとも日付が存在する必要がある。不正確または「あいまいな」時間を記録するには（たとえば、「朝食後」に行われた血糖測定）、[Timing]（datatypes.html＃timing）データ型を使用して、測定を通常のライフイベントに関連付けることができる。

Knowing when an observation was deemed true is important to its relevance as well as determining trends.

The date and time this version of the observation was made available to providers, typically after the results have been reviewed and verified. このバージョンのレポートが医療者に提供された日時。通常、レポートがレビューおよび検証された後となる。

For Observations that don’t require review and verification, it may be the same as the lastUpdated time of the resource itself. For Observations that do require review and verification for certain updates, it might not be the same as the lastUpdated time of the resource itself due to a non-clinically significant update that doesn’t require the new version to be reviewed and verified again. レビューと検証を必要としないobservationの場合、リソース自体の[lastUpdated]（resource-definitions.html＃Meta.lastUpdated）日時と同じになる場合がある。特定の更新のレビューと検証が必要なobservationの場合、新しいバージョンを再度レビューして検証する必要がないような臨床的に重要でない更新がなされたために、リソース自体の「lastUpdated」時間はこれと異なる場合がある。

Who was responsible for asserting the observed value as "true". そのobservationは真だと言える責任者

References SHALL be a reference to an actual FHIR resource, and SHALL be resolvable (allowing for access control, temporary unavailability, etc.). Resolution can be either by retrieval from the URL, or, where applicable by resource type, by treating an absolute reference as a canonical URL and looking it up in a local registry/repository. 参照は、実際のFHIRリソースへの参照である必要があり、解決可能（内容に到達可能）である必要がある（アクセス制御、一時的な使用不可などを考慮に入れる）。解決は、URLから取得するか、リソースタイプによって該当する場合は、絶対参照を正規URLとして扱い、ローカルレジストリ/リポジトリで検索することによって行うことができる。

May give a degree of confidence in the observation and also indicates where follow-up questions should be directed.

Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

An Extension

A reference to a location at which the other resource is found. The reference may be a relative reference, in which case it is relative to the service base URL, or an absolute URL that resolves to the location where the resource is found.

Aa resource (or, for logical models, the URI of the logical model).

This is generally not the same as the Resource.text of the referenced resource. The purpose is to identify what's being referenced, not to fully describe it.

The information determined as a result of making the observation, if the information has a simple value. 結果情報が単純な値である場合、observationを行った結果として決定された情報。

An observation may have; 1) a single value here, 2) both a value and a set of related or component values, or 3) only a set of related or component values. If a value is present, the datatype for this element should be determined by Observation.code. A CodeableConcept with just a text would be used instead of a string if the field was usually coded, or if the type associated with the Observation.code defines a coded value. For additional guidance, see the Notes section below.

An observation exists to have a value, though it might not if it is in error, or if it represents a group of observations.

Provides a reason why the expected value in the element Observation.value[x] is missing. Observation.value[x] 要素に期待される結果が存在しない理由を設定する。

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.

ヌル値または例外値は、FHIRオブザベーションで2つの方法で表すことができる。 1つの方法は、それらを値セットに含めて、値の例外を表す方法である。たとえば、血清学的検査の測定値は、「検出された」、「検出されなかった」、「決定的でない」、または「検体が不十分」である可能性がある。別の方法は、実際の観測にvalue要素を使用し、明示的なdataAbsentReason要素を使用して例外的な値を記録することである。たとえば、測定が完了しなかった場合、dataAbsentReasonコード「error」を使用できる。この場合には、観測値は、報告する値がある場合にのみ報告される可能性があることに注意する必要がある。たとえば、差分セルカウント値は> 0の場合にのみ報告される場合がある。これらのオプションのため、nullまたは例外値の一般的な観測値を解釈するにはユースケースの合意が必要である。

Codes specifying why the result (Observation.value[x]) is missing.

For many results it is necessary to handle exceptional values in measurements.

A categorical assessment of an observation value. For example, high, low, normal. 観測値のカテゴリ別評価。たとえば、高、低、通常。

Historically used for laboratory results (known as 'abnormal flag' ), its use extends to other use cases where coded interpretations are relevant. Often reported as one or more simple compact codes this element is often placed adjacent to the result value in reports and flow sheets to signal the meaning/normalcy status of the result.

「異常フラグ」として呼ばれる検査結果解釈コードが従来から使用されており、その使用はコード化された解釈が関連するような他の場合でも拡大して使われている。多くの場合、1つ以上の単純でコンパクトなコードとして報告され、この要素は、結果の意味や正常かどうかを示すために、レポートや時系列表で結果値の隣に配置されることがよくある。

Codes identifying interpretations of observations.

For some results, particularly numeric results, an interpretation is necessary to fully understand the significance of a result. 一部の結果、特に数値結果については、結果の意義を完全に理解するためには解釈コードが必要である。

Comments about the observation or the results. 観測値、結果に対するコメント

May include general statements about the observation, or statements about significant, unexpected or unreliable results values, or information about its source when relevant to its interpretation.

観察（結果）に関する一般的な記述、重要な、予期しない、または信頼できない結果値に関する記述、またはその解釈に関連する場合はそのソースに関する情報が含まれる場合がある。

Need to be able to provide free text additional information. フリーテキストの追加情報を提供できる必要がある。

Indicates the site on the subject's body where the observation was made (i.e. the target site).

Only used if not implicit in code found in Observation.code. In many systems, this may be represented as a related observation instead of an inline component.

If the use case requires BodySite to be handled as a separate resource (e.g. to identify and track separately) then use the standard extension bodySite.

Codes describing anatomical locations. May include laterality.

Indicates the mechanism used to perform the observation.

Only used if not implicit in code for Observation.code.

Methods for simple observations.

In some cases, method can impact results and is thus used for determining whether results can be compared or determining significance of results.

The specimen that was used when this observation was made. この観察（観測、検査）が実施されたときに使われた検体材料

Should only be used if not implicit in code found in Observation.code. Observations are not made on specimens themselves; they are made on a subject, but in many cases by the means of a specimen. Note that although specimens are often involved, they are not always tracked and reported explicitly. Also note that observation resources may be used in contexts that track the specimen explicitly (e.g. Diagnostic Report). Observation.codeにあるコードで暗黙的に示されない場合にのみ使用する必要がある。検体自体の観察は行われない。観察（観測、検査）対象者に対して実施されるが、多くの場合には対象者から得られた検体に対して実施される。検体が奥の場合に関わるが、それらは常に追跡され、明示的に報告されるとは限らないことに注意すること。またobservationリソースは、検体を明示的に記述するような状況下（診断レポートなど）で使用される場合があることに注意。

The device used to generate the observation data. 観察データを生成するために使われた機器

Note that this is not meant to represent a device involved in the transmission of the result, e.g., a gateway. Such devices may be documented using the Provenance resource where relevant. これは、結果の送信に関与するデバイス（ゲートウェイなど）を表すことを意図したものではない。そのようなデバイスは、必要に応じてProvenanceリソースを使用して文書化する。

Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

An Extension

A reference to a location at which the other resource is found. The reference may be a relative reference, in which case it is relative to the service base URL, or an absolute URL that resolves to the location where the resource is found. The reference may be version specific or not. If the reference is not to a FHIR RESTful server, then it should be assumed to be version specific. Internal fragment references (start with '#') refer to contained resources.

Using absolute URLs provides a stable scalable approach suitable for a cloud/web context, while using relative/logical references provides a flexible approach suitable for use when trading across closed eco-system boundaries. Absolute URLs do not need to point to a FHIR RESTful server, though this is the preferred approach. If the URL conforms to the structure "/[type]/[id]" then it should be assumed that the reference is to a FHIR RESTful server.

The expected type of the target of the reference. If both Reference.type and Reference.reference are populated and Reference.reference is a FHIR URL, both SHALL be consistent.

The type is the Canonical URL of Resource Definition that is the type this reference refers to. References are URLs that are relative to http://hl7.org/fhir/StructureDefinition/ e.g. "Patient" is a reference to http://hl7.org/fhir/StructureDefinition/Patient. Absolute URLs are only allowed for logical models (and can only be used in references in logical models, not resources).

This element is used to indicate the type of the target of the reference. This may be used which ever of the other elements are populated (or not). In some cases, the type of the target may be determined by inspection of the reference (e.g. a RESTful URL) or by resolving the target of the reference; if both the type and a reference is provided, the reference SHALL resolve to a resource of the same type as that specified.

Aa resource (or, for logical models, the URI of the logical model).

An identifier for the target resource. This is used when there is no way to reference the other resource directly, either because the entity it represents is not available through a FHIR server, or because there is no way for the author of the resource to convert a known identifier to an actual location. There is no requirement that a Reference.identifier point to something that is actually exposed as a FHIR instance, but it SHALL point to a business concept that would be expected to be exposed as a FHIR instance, and that instance would need to be of a FHIR resource type allowed by the reference.

When an identifier is provided in place of a reference, any system processing the reference will only be able to resolve the identifier to a reference if it understands the business context in which the identifier is used. Sometimes this is global (e.g. a national identifier) but often it is not. For this reason, none of the useful mechanisms described for working with references (e.g. chaining, includes) are possible, nor should servers be expected to be able resolve the reference. Servers may accept an identifier based reference untouched, resolve it, and/or reject it - see CapabilityStatement.rest.resource.referencePolicy.

When both an identifier and a literal reference are provided, the literal reference is preferred. Applications processing the resource are allowed - but not required - to check that the identifier matches the literal reference

Applications converting a logical reference to a literal reference may choose to leave the logical reference present, or remove it.

Reference is intended to point to a structure that can potentially be expressed as a FHIR resource, though there is no need for it to exist as an actual FHIR resource instance - except in as much as an application wishes to actual find the target of the reference. The content referred to be the identifier must meet the logical constraints implied by any limitations on what resource types are permitted for the reference. For example, it would not be legitimate to send the identifier for a drug prescription if the type were Reference(Observation|DiagnosticReport). One of the use-cases for Reference.identifier is the situation where no FHIR representation exists (where the type is Reference (Any).

Plain text narrative that identifies the resource in addition to the resource reference.

This is generally not the same as the Resource.text of the referenced resource. The purpose is to identify what's being referenced, not to fully describe it.

Guidance on how to interpret the value by comparison to a normal or recommended range. Multiple reference ranges are interpreted as an "OR". In other words, to represent two distinct target populations, two referenceRange elements would be used.

Most observations only have one generic reference range. Systems MAY choose to restrict to only supplying the relevant reference range based on knowledge about the patient (e.g., specific to the patient's age, gender, weight and other factors), but this might not be possible or appropriate. Whenever more than one reference range is supplied, the differences between them SHOULD be provided in the reference range and/or age properties. 通常の範囲または推奨範囲と比較して値を解釈する方法に関するガイダンス。複数の参照範囲は「OR」として解釈される。つまり、2つの異なるターゲット母集団を表すために、2つの referenceRange要素が使用される。

Knowing what values are considered "normal" can help evaluate the significance of a particular result. Need to be able to provide multiple reference ranges for different contexts. どの値が「正常」と見なされるかを知ることは、特定の結果の意義を評価するのに役立つ。さまざまなコンテキストに対応するため複数の参照範囲を提供できる必要がある。

This observation is a group observation (e.g. a battery, a panel of tests, a set of vital sign measurements) that includes the target as a member of the group. このobservationは、グループのメンバーとしてターゲットを含むグループobservation（たとえば、一連検査セット、パネル検査、バイタルサイン測定値のセット）である。

When using this element, an observation will typically have either a value or a set of related resources, although both may be present in some cases. For a discussion on the ways Observations can assembled in groups together, see Notes below. Note that a system may calculate results from QuestionnaireResponse into a final score and represent the score as an Observation. この要素を使用する場合、observationには通常、値または関連するリソースのセットのいじれかを含む。その両方を含む場合もある。複数のobservationをグループに一緒にまとめる方法については、以下の[メモ]（observation.html＃obsgrouping）を参照せよ。システムは、[QuestionnaireResponse]（questionnaireresponse.html）からの結果を計算して最終スコアにし、そのスコアをobservationとして表す場合があることに注意。

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. 一部の観測には、複数のコンポーネントの観測がある。これらのコンポーネントの観察結果は、同じ属性を共有する個別のコード値のペアとして表される。例としては、血圧測定のための収縮期および拡張期のコンポーネントの観察や、遺伝学の観察のための複数のコンポーネントの観察がある。

For a discussion on the ways Observations can be assembled in groups together see Notes below. 複数のObservation をグループに一緒にまとめる方法については、以下の[Notes]（observation.html＃notes）を参照すること。

Component observations share the same attributes in the Observation resource as the primary observation and are always treated a part of a single observation (they are not separable). 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. コンポーネントobservation は プライマリobservation としてのobservation リソースの中で同じ属性を共有し、常に単一のobservation の一部として扱われる（つまりそれらは分離可能ではないん）。ただし、プライマリobservationのreference rangeはコンポーネント値に継承されないため、reference rangeは各コンポーネントobservation に適切であれば必要である。

The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes.

The only time that a resource does not have an id is when it is being submitted to the server using a create operation.

The metadata about the resource. This is content that is maintained by the infrastructure. Changes to the content might not always be associated with version changes to the resource.

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.

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.

The base language in which the resource is written.

Language is provided to support indexing and accessibility (typically, services such as text to speech use the language tag). The html language tag in the narrative applies to the narrative. The language tag on the resource may be used to specify the language of other presentations generated from the data in the resource. Not all the content has to be in the base language. The Resource.language should not be assumed to apply to the narrative automatically. If a language is specified, it should it also be specified on the div element in the html (see rules in HTML5 for information about the relationship between xml:lang and the html lang attribute).

A human language.

A human-readable narrative that contains a summary of the resource and can be used to represent the content of the resource to a human. The narrative need not encode all the structured data, but is required to contain sufficient detail to make it "clinically safe" for a human to just read the narrative. Resource definitions may define what content should be represented in the narrative to ensure clinical safety.

Contained resources do not have narrative. Resources that are not contained SHOULD have a narrative. In some cases, a resource may only have text with little or no additional discrete data (as long as all minOccurs=1 elements are satisfied). This may be necessary for data from legacy systems where information is captured as a "text blob" or where text is additionally entered raw or narrated and encoded information is added later.

These resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, and nor can they have their own independent transaction scope.

This should never be done when the content can be identified properly, as once identification is lost, it is extremely difficult (and context dependent) to restore it again. Contained resources may have profiles and tags In their meta elements, but SHALL NOT have security labels.

An Extension

A unique identifier assigned to this observation. Observationに割り当てられたユニーク（一意）の識別ID

Allows observations to be distinguished and referenced.

A plan, proposal or order that is fulfilled in whole or in part by this event. For example, a MedicationRequest may require a patient to have laboratory test performed before it is dispensed. このイベントによって全体または部分的に実施されるプラン、提案、依頼。たとえばMedicationRequest は調剤される前に臨床検査を患者に行う必要があるかもしれない。

Allows tracing of authorization for the event and tracking whether proposals/recommendations were acted upon.

A larger event of which this particular Observation is a component or step. For example, an observation as part of a procedure. この特定のObservationが別のより大きなイベントの要素あるいは一段階であるような親イベント。たとえば、一連の処置手順の一部としてのObservation。

To link an Observation to an Encounter use encounter. See the Notes below for guidance on referencing another Observation. ObservationをEncounterにencounter要素を使ってリンクする。もうひとつ別のObservationを参照することについては、以降にあるt Notes　をガイダンスとして参照のこと。

The status of the result value.　結果値のステータス。

This element is labeled as a modifier because the status contains codes that mark the resource as not currently valid. このリソースは現在有効でないというマークをするコードを含んでいるため、この要素はモディファイアー（修飾的要素）として位置づけられている。

Codes providing the status of an observation.

Need to track the status of individual results. Some results are finalized before the whole report is finalized.

A code that classifies the general type of observation being made. 実施されているobservationの一般的なタイプを分類するコード

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. The level of granularity is defined by the category concepts in the value set. 必要なカテゴリ値セットに加えて、この要素を使用すると、所有者のカテゴリの定義に基づいたさまざまなカテゴリ化スキームが可能になり、複数のカテゴリを一度に効果的に使用できる。粒度のレベルは、値セットのカテゴリの概念によって定義される。

Codes for high level observation categories.

Used for filtering what observations are retrieved and displayed.

Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

An Extension

A reference to a code defined by a terminology system.

Codes may be defined very casually in enumerations, or code lists, up to very formal definitions such as SNOMED CT - see the HL7 v3 Core Principles for more information. Ordering of codings is undefined and SHALL NOT be used to infer meaning. Generally, at most only one of the coding values will be labeled as UserSelected = true.

Allows for alternative encodings within a code system, and translations to other code systems.

A human language representation of the concept as seen/selected/uttered by the user who entered the data and/or which represents the intended meaning of the user.

Very often the text is the same as a displayName of one of the codings.

The codes from the terminologies do not always capture the correct meaning with all the nuances of the human using them, or sometimes there is no appropriate code at all. In these cases, the text is used to capture the full meaning of the source.

Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

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.

A reference to a code defined by a terminology system.

Codes may be defined very casually in enumerations, or code lists, up to very formal definitions such as SNOMED CT - see the HL7 v3 Core Principles for more information. Ordering of codings is undefined and SHALL NOT be used to infer meaning. Generally, at most only one of the coding values will be labeled as UserSelected = true.

Allows for alternative encodings within a code system, and translations to other code systems.

Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

An Extension

The identification of the code system that defines the meaning of the symbol in the code.

The URI may be an OID (urn:oid:...) or a UUID (urn:uuid:...). OIDs and UUIDs SHALL be references to the HL7 OID registry. Otherwise, the URI should come from HL7's list of FHIR defined special URIs or it should reference to some definition that establishes the system clearly and unambiguously.

Need to be unambiguous about the source of the definition of the symbol.

The version of the code system which was used when choosing this code. Note that a well-maintained code system does not need the version reported, because the meaning of codes is consistent across versions. However this cannot consistently be assured, and when the meaning is not guaranteed to be consistent, the version SHOULD be exchanged.

Where the terminology does not clearly define what string should be used to identify code system versions, the recommendation is to use the date (expressed in FHIR date format) on which that version was officially published as the version date.

A symbol in syntax defined by the system. The symbol may be a predefined code or an expression in a syntax defined by the coding system (e.g. post-coordination).

Need to refer to a particular code in the system.

A representation of the meaning of the code in the system, following the rules of the system.

Need to be able to carry a human-readable meaning of the code for readers that do not know the system.

Indicates that this coding was chosen by a user directly - e.g. off a pick list of available items (codes or displays).

Amongst a set of alternatives, a directly chosen code is the most appropriate starting point for new translations. There is some ambiguity about what exactly 'directly chosen' implies, and trading partner agreement may be needed to clarify the use of this element and its consequences more completely.

This has been identified as a clinical safety criterium - that this exact system/code pair was chosen explicitly, rather than inferred by the system based on some rules or language processing.

A human language representation of the concept as seen/selected/uttered by the user who entered the data and/or which represents the intended meaning of the user.

Very often the text is the same as a displayName of one of the codings.

The codes from the terminologies do not always capture the correct meaning with all the nuances of the human using them, or sometimes there is no appropriate code at all. In these cases, the text is used to capture the full meaning of the source.

Describes what was observed. Sometimes this is called the observation "name".

observationの対象物を記述する。 observation の名前で呼ばれることもある。

All code-value and, if present, component.code-component.value pairs need to be taken into account to correctly understand the meaning of the observation. observationの意味を正しく理解するには、すべてのcode-valueペアと、さらに存在する場合にはcomponent.code-component.valueのペアが、考慮される必要がある。
