    Observation Class

    Measurements and simple assertions made about a patient, device or other subject.

    Observations are a key aspect of healthcare. This resource is used to capture those that do not require more sophisticated mechanisms.

    FHIR Specification

    • Short: Measurements and simple assertions
    • Definition: Measurements and simple assertions made about a patient, device or other subject.
    • Comment: 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.

    Observation.status Element

    FHIR Specification

    • Short: registered | preliminary | final | amended +
    • Definition: The status of the result value.
    • Comment: This element is labeled as a modifier because the status contains codes that mark the resource as not currently valid.

    category?: CodeableConcept[]

    Observation.category Element

    FHIR Specification

    • Short: Classification of type of observation
    • Definition: A code that classifies the general type of observation being made.
    • Comment: 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.
    • Requirements: Used for filtering what observations are retrieved and displayed.
    • FHIR Type: CodeableConcept

    Observation.code Element

    FHIR Specification

    • Short: Type of observation (code / type)
    • Definition: Describes what was observed. Sometimes this is called the observation "name".
    • Comment: 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.
    • Requirements: Knowing what kind of observation is being made is essential to understanding the observation.

    subject?: Reference

    Observation.subject Element

    FHIR Specification

    focus?: Reference[]

    Observation.focus Element

    FHIR Specification

    • Short: What the observation is about, when it is not about the subject of record
    • Definition: 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.
    • Comment: 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.
    • FHIR Type: Reference
    • Cardinality: 0..*
    • isModifier: false
    • isSummary: true
    encounter?: Reference

    Observation.encounter Element

    FHIR Specification

    • Short: Healthcare event during which this observation is made
    • Definition: The healthcare event (e.g. a patient and healthcare provider interaction) during which this observation is made.
    • Comment: 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).
    • Requirements: For some observations it may be important to know the link between an observation and a particular encounter.
    • FHIR Type: Reference
    • Cardinality: 0..1
    • isModifier: false
    • isSummary: true
    effective?: IDataType

    Observation.effective[x] Element

    @ChoiceDataTypesMeta('Observation.effective[x]', ['dateTime','Period','Timing','instant',]

    FHIR Specification

    • Short: Clinically relevant time/time-period for observation
    • Definition: 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.
    • Comment: 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.
    • Requirements: Knowing when an observation was deemed true is important to its relevance as well as determining trends.
    • FHIR Types: 'dateTime', 'Period', 'Timing', 'instant',
    • Cardinality: 0..1
    • isModifier: false
    • isSummary: true
    issued?: InstantType

    Observation.issued Element

    FHIR Specification

    • Short: Date/Time this version was made available
    • Definition: The date and time this version of the observation was made available to providers, typically after the results have been reviewed and verified.
    • Comment: 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.
    • FHIR Type: instant
    • Cardinality: 0..1
    • isModifier: false
    • isSummary: true
    performer?: Reference[]

    Observation.performer Element

    FHIR Specification

    value?: IDataType

    Observation.value[x] Element

    @ChoiceDataTypesMeta('Observation.value[x]', ['Quantity','CodeableConcept','string','boolean','integer','Range','Ratio','SampledData','time','dateTime','Period',]

    FHIR Specification

    • Short: Actual result
    • Definition: The information determined as a result of making the observation, if the information has a simple value.
    • Comment: 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.
    • Requirements: An observation exists to have a value, though it might not if it is in error, or if it represents a group of observations.
    • FHIR Types: 'Quantity', 'CodeableConcept', 'string', 'boolean', 'integer', 'Range', 'Ratio', 'SampledData', 'time', 'dateTime', 'Period',
    • Cardinality: 0..1
    • isModifier: false
    • isSummary: true
    dataAbsentReason?: CodeableConcept

    Observation.dataAbsentReason Element

    FHIR Specification

    • Short: Why the result is missing
    • Definition: Provides a reason why the expected value in the element Observation.value[x] is missing.
    • Comment: 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.
    • Requirements: For many results it is necessary to handle exceptional values in measurements.
    • FHIR Type: CodeableConcept
    • Cardinality: 0..1
    • isModifier: false
    • isSummary: false
    interpretation?: CodeableConcept[]

    Observation.interpretation Element

    FHIR Specification

    • Short: High, low, normal, etc.
    • Definition: A categorical assessment of an observation value. For example, high, low, normal.
    • Comment: 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.
    • Requirements: For some results, particularly numeric results, an interpretation is necessary to fully understand the significance of a result.
    • FHIR Type: CodeableConcept
    • Cardinality: 0..*
    • isModifier: false
    • isSummary: false
    note?: Annotation[]

    Observation.note Element

    FHIR Specification

    • Short: Comments about the observation
    • Definition: Comments about the observation or the results.
    • Comment: 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.
    • Requirements: Need to be able to provide free text additional information.
    • FHIR Type: Annotation
    • Cardinality: 0..*
    • isModifier: false
    • isSummary: false
    bodySite?: CodeableConcept

    Observation.bodySite Element

    FHIR Specification

    • Short: Observed body part
    • Definition: Indicates the site on the subject's body where the observation was made (i.e. the target site).
    • Comment: 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.
    • FHIR Type: CodeableConcept
    • Cardinality: 0..1
    • isModifier: false
    • isSummary: false
    method?: CodeableConcept

    Observation.method Element

    FHIR Specification

    • Short: How it was done
    • Definition: Indicates the mechanism used to perform the observation.
    • Comment: Only used if not implicit in code for Observation.code.
    • Requirements: In some cases, method can impact results and is thus used for determining whether results can be compared or determining significance of results.
    • FHIR Type: CodeableConcept
    • Cardinality: 0..1
    • isModifier: false
    • isSummary: false
    specimen?: Reference

    Observation.specimen Element

    FHIR Specification

    • Short: Specimen used for this observation
    • Definition: The specimen that was used when this observation was made.
    • Comment: 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).
    • FHIR Type: Reference
    • Cardinality: 0..1
    • isModifier: false
    • isSummary: false
    device?: Reference

    Observation.device Element

    FHIR Specification

    referenceRange?: ObservationReferenceRangeComponent[]

    Observation.referenceRange Element

    FHIR Specification

    • Short: Provides guide for interpretation
    • Definition: 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.
    • Comment: 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.
    • Requirements: 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.
    • FHIR Type: BackboneElement
    • Cardinality: 0..*
    • isModifier: false
    • isSummary: false
    hasMember?: Reference[]

    Observation.hasMember Element

    FHIR Specification

    derivedFrom?: Reference[]

    Observation.derivedFrom Element

    FHIR Specification

    component?: ObservationComponentComponent[]

    Observation.component Element

    FHIR Specification

    • Short: Component results
    • Definition: 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.
    • Comment: For a discussion on the ways Observations can be assembled in groups together see Notes below.
    • Requirements: 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.
    • FHIR Type: BackboneElement
    • Cardinality: 0..*
    • isModifier: false
    • isSummary: true
