BodySite

Knowing where the observation is made is important for tracking if multiple sites are possible.

Declaration

public CodeableConcept BodySite { get; set; }

Property Value

Type	Description
CodeableConcept

Category

A code that classifies the general type of observation being made. This is used for searching, sorting and display purposes.

Declaration

public CodeableConcept Category { get; set; }

Property Value

Type	Description
CodeableConcept

Code

Knowing what kind of observation is being made is essential to understanding the observation.

Declaration

public CodeableConcept Code { get; set; }

Property Value

Type	Description
CodeableConcept

Comments

Need to be able to provide free text additional information.

Declaration

public string Comments { get; set; }

Property Value

Type	Description
System.String

Component

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.

Declaration

public List<ObservationComponent> Component { get; set; }

Property Value

Type	Description
fhirCsR2.Models.List<ObservationComponent>

DataAbsentReason

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

Declaration

public CodeableConcept DataAbsentReason { get; set; }

Property Value

Type	Description
CodeableConcept

Device

The device used to generate the observation data.

Declaration

public Reference Device { get; set; }

Property Value

Type	Description
Reference

EffectiveDateTime

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

Declaration

public string EffectiveDateTime { get; set; }

Property Value

Type	Description
System.String

EffectivePeriod

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

Declaration

public Period EffectivePeriod { get; set; }

Property Value

Type	Description
Period

Encounter

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

Declaration

public Reference Encounter { get; set; }

Property Value

Type	Description
Reference

Identifier

Allows observations to be distinguished and referenced.

Declaration

public List<Identifier> Identifier { get; set; }

Property Value

Type	Description
fhirCsR2.Models.List<Identifier>

Interpretation

For some results, particularly numeric results, an interpretation is necessary to fully understand the significance of a result.

Declaration

public CodeableConcept Interpretation { get; set; }

Property Value

Type	Description
CodeableConcept

Issued

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

Declaration

public string Issued { get; set; }

Property Value

Type	Description
System.String

Method

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

Declaration

public CodeableConcept Method { get; set; }

Property Value

Type	Description
CodeableConcept

Performer

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

Declaration

public List<Reference> Performer { get; set; }

Property Value

Type	Description
fhirCsR2.Models.List<Reference>

ReferenceRange

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.

Declaration

public List<ObservationReferenceRange> ReferenceRange { get; set; }

Property Value

Type	Description
fhirCsR2.Models.List<ObservationReferenceRange>

Related

Normally, an observation will have either a value or a set of related observations. A few observations (e.g. Apgar score) may have both a value and a set of related observations or sometimes QuestionnaireResponse from which the measure is derived.

Declaration

public List<ObservationRelated> Related { get; set; }

Property Value

Type	Description
fhirCsR2.Models.List<ObservationRelated>
