Observation Definition
Observations are a central element in healthcare, used to support the diagnosis, monitor progress, determine baselines and patterns and even capture demographic characteristics. Most observations are simple name/value pair assertions with some metadata, but some observations group other observations together logically, or even are multi-component observations.

Description
At its core, Observation allows expressing a name-value pair or structured collection of name-value pairs. As such, it can support conveying any type of information desired. However, that is not its intent. Observation is intended for capturing measurements and subjective point-in-time assessments. It is not intended to be used for those specific contexts and use cases already covered by other FHIR resources. For example, the Allergy Intolerance resource represents patient allergies, Medication Statement resource: medications taken by a patient, Family Member History resource: a patient’s family history, Procedure resource: information about a procedure, and Questionnaire Response resource: a set of answers to a set of questions.
The Observation resource should not be used to record clinical diagnosis about a patient or subject that are typically captured in the Condition resource or the Clinical Impression resource. The Observation resource is often referenced by the Condition resource to provide specific subjective and objective data to support its assertions. There will however be situations of overlap. For example, a response to a question of “have you ever taken illicit drugs” could in principle be represented using Medication Statement, but most systems would treat such an assertion as an Observation. In some cases, such as when source data is coming from a Health Level Seven International (HL7) volume two feed, a system might not have information that allows it to distinguish diagnosis, allergy and other “specialized” types of observations from laboratory, vital sign and other observation types intended to be conveyed with this resource. In those circumstances, such specialized observations may also appear using this resource. Adhering to such convention is an appropriate use of Observation. If implementers are uncertain whether a proposed use of Observation is appropriate, they’re encouraged to consult with implementers.

Data Fields
Name | Description | Type | Constraints |
---|---|---|---|
Concept_Name | Name of the concept in the FHIR structure. | string | required : 1 |
Computer_Ready_Name | A Computer-ready name (e.g. a token) that identifies the structure - suitable for code generation. Note that this name (and other names relevant for code generation, including element & slice names, codes etc) may collide with reserved words in the relevant target language, and code generators will need to handle this. | string | - |
Type | The type the structure describes. | string | - |
Dollar_Ref | The "$ref" string value contains a Uniform Resource Identifier (URI) which identifies the location of the JSON value being referenced. | string | - |
Description | A free text natural language description of the structure and its use. | string | - |
Items | The value of the keyword should be an object or an array of objects. If the keyword value is an object, then for the data array to be valid each item of the array should be valid according to the schema in this value. | string | - |
Enum | The enum is used to restrict a value to a fixed set of values. It must be an array with at least one element, where each element is unique. | string | - |
Required | The value of the keyword should be an array of unique strings. The data object to be valid should contain all properties with names equal to the elements in the keyword value. | string | - |
Const | The value of this keyword can be anything. The data is valid if it is deeply equal to the value of the keyword. | string | - |
