Properties

Public property identifier : TIdentifierArray read GetidentifierArray;

A unique identifier assigned to this observation.

Public property basedOn : TReferenceArray read GetbasedOnArray;

A plan, proposal or order that is fulfilled in whole or in part by this event.

Public property status : string read Getstatus write Setstatus;

The status of the result value.

Public property statusElement : TObservationStatus read GetstatusElement write SetstatusElement;
 
Public property category : TCodeableConceptArray read GetcategoryArray;

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

Public property code : TCodeableConcept read Getcode write Setcode;

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

Public property subject : TReference read Getsubject write Setsubject;

The patient, or group of patients, location, or device whose characteristics (direct or indirect) are described by the observation and into whose record the observation is placed. Comments: Indirect characteristics may be those of a specimen, fetus, donor, other observer (for example a relative or EMT), or any observation made about the subject.

Public property context : TReference read Getcontext write Setcontext;

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

Public property effective : TElement read Geteffective write Seteffective;

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.

Public property issued : string read Getissued write Setissued;

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

Public property issuedElement : Tinstant read GetissuedElement write SetissuedElement;
 
Public property performer : TReferenceArray read GetperformerArray;

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

Public property value : TElement read Getvalue write Setvalue;

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

Public property dataAbsentReason : TCodeableConcept read GetdataAbsentReason write SetdataAbsentReason;

Provides a reason why the expected value in the element Observation.value[x] is missing.

Public property interpretation : TCodeableConcept read Getinterpretation write Setinterpretation;

The assessment made based on the result of the observation. Intended as a simple compact code often placed adjacent to the result value in reports and flow sheets to signal the meaning/normalcy status of the result. Otherwise known as abnormal flag.

Public property comment : string read Getcomment write Setcomment;

May include statements about significant, unexpected or unreliable values, or information about the source of the value where this may be relevant to the interpretation of the result.

Public property commentElement : Tstring read GetcommentElement write SetcommentElement;
 
Public property bodySite : TCodeableConcept read GetbodySite write SetbodySite;

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

Public property method : TCodeableConcept read Getmethod write Setmethod;

Indicates the mechanism used to perform the observation.

Public property specimen : TReference read Getspecimen write Setspecimen;

The specimen that was used when this observation was made.

Public property device : TReference read Getdevice write Setdevice;

The device used to generate the observation data.

Public property referenceRange : TObservationReferenceRangeArray read GetreferenceRangeArray;

Guidance on how to interpret the value by comparison to a normal or recommended range.

Public property related : TObservationRelatedArray read GetrelatedArray;

A reference to another resource (usually another Observation) whose relationship is defined by the relationship type code.

Public property component : TObservationComponentArray read GetcomponentArray;

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.
