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

resourceType This is a Observation resource

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

meta 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.

implicitRules 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.

implicitRulesElement Extensions for implicitRules

language The base language in which the resource is written.

languageElement Extensions for language

text 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 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.

extension_ May be used to represent additional information that is not part of the basic definition of the resource. 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.

modifierExtension 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).

identifier A unique identifier assigned to this observation.

basedOn 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.

partOf A larger event of which this particular Observation is a component or step. For example, an observation as part of a procedure.

status The status of the result value.

statusElement Extensions for status

category A code that classifies the general type of observation being made.

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

subject 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.

focus 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.

encounter The healthcare event (e.g. a patient and healthcare provider interaction) during which this observation is made.

effectiveDateTime 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.

effectiveDateTimeElement Extensions for effectiveDateTime

effectivePeriod 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.

effectiveTiming 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.

effectiveInstant 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.

effectiveInstantElement Extensions for effectiveInstant

issued The date and time this version of the observation was made available to providers, typically after the results have been reviewed and verified.

issuedElement Extensions for issued

performer Who was responsible for asserting the observed value as "true".

valueQuantity The information determined as a result of making the observation, if the information has a simple value.

valueCodeableConcept The information determined as a result of making the observation, if the information has a simple value.

valueString The information determined as a result of making the observation, if the information has a simple value.

valueInteger The information determined as a result of making the observation, if the information has a simple value.

valueIntegerElement Extensions for valueInteger

valueRange The information determined as a result of making the observation, if the information has a simple value.

valueRatio The information determined as a result of making the observation, if the information has a simple value.

valueSampledData The information determined as a result of making the observation, if the information has a simple value.

valueTime The information determined as a result of making the observation, if the information has a simple value.

valueTimeElement Extensions for valueTime

valueDateTime The information determined as a result of making the observation, if the information has a simple value.

valueDateTimeElement Extensions for valueDateTime

valuePeriod The information determined as a result of making the observation, if the information has a simple value.

dataAbsentReason Provides a reason why the expected value in the element Observation.valuex is missing.

interpretation A categorical assessment of an observation value. For example, high, low, normal.

note Comments about the observation or the results.

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

method Indicates the mechanism used to perform the observation.

specimen The specimen that was used when this observation was made.

device The device used to generate the observation data.

referenceRange 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.

hasMember 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.

derivedFrom The target resource that represents a measurement from which this observation value is derived. For example, a calculated anion gap or a fetal measurement based on an ultrasound image.

component 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.
