Set of definitional characteristics for a kind of observation or measurement produced or consumed by an orderable health care service. Set of definitional characteristics for a kind of observation or measurement produced or consumed by an orderable health care service. If the element is present, it must have either a @value, an @id, or extensions An absolute URL that is used to identify this ObservationDefinition when it is referenced in a specification, model, design or an instance. This SHALL be a URL, SHOULD be globally unique, and SHOULD be an address at which this ObservationDefinition is (or will be) published. The URL SHOULD include the major version of the ObservationDefinition. For more information see Technical and Business Versions. Business identifiers assigned to this ObservationDefinition by the performer and/or other systems. These identifiers remain constant as the resource is updated and propagates from server to server. The identifier that is used to identify this version of the ObservationDefinition when it is referenced in a specification, model, design or instance. This is an arbitrary value managed by the ObservationDefinition author and is not expected to be globally unique. For example, it might be a timestamp (e.g. yyyymmdd) if a managed version is not available. There is also no expectation that versions are orderable. Indicates the mechanism used to compare versions to determine which is more current. A natural language name identifying the ObservationDefinition. This name should be usable as an identifier for the module by machine processing applications such as code generation. A short, descriptive, user-friendly title for the ObservationDefinition. The current state of the ObservationDefinition. A flag to indicate that this ObservationDefinition is authored for testing purposes (or education/evaluation/marketing), and is not intended to be used for genuine usage. The date (and optionally time) when the ObservationDefinition was last significantly changed. The date must change when the business version changes and it must change if the status code changes. In addition, it should change when the substantive content of the ObservationDefinition changes. Helps establish the "authority/credibility" of the ObservationDefinition. May also allow for contact. Contact details to assist a user in finding and communicating with the publisher. A free text natural language description of the ObservationDefinition from the consumer's perspective. The content was developed with a focus and intent of supporting the contexts that are listed. These contexts may be general categories (gender, age, ...) or may be references to specific programs (insurance plans, studies, ...) and may be used to assist with indexing and searching for appropriate ObservationDefinition instances. A jurisdiction in which the ObservationDefinition is intended to be used. Explains why this ObservationDefinition is needed and why it has been designed as it has. Copyright statement relating to the ObservationDefinition and/or its contents. Copyright statements are notices of intellectual property ownership and can include restrictions on the use and publishing of the ObservationDefinition. A short string (<50 characters), suitable for inclusion in a page footer that identifies the copyright holder, effective period, and optionally whether rights are restricted. (e.g. 'All rights reserved', 'Some rights reserved'). The date on which the asset content was approved by the publisher. Approval happens once when the content is officially approved for usage. The date on which the asset content was last reviewed. Review happens periodically after that, but doesn't change the original approval date. The period during which the ObservationDefinition content was or is planned to be effective. The canonical URL pointing to another FHIR-defined ObservationDefinition that is adhered to in whole or in part by this definition. The URL pointing to an externally-defined observation definition, guideline or other definition that is adhered to in whole or in part by this definition. A code that describes the intended kind of subject of Observation instances conforming to this ObservationDefinition. The type of individual/organization/device that is expected to act upon instances of this definition. A code that classifies the general type of observation. Describes what will be observed. Sometimes this is called the observation "name". The data types allowed for the value element of the instance observations conforming to this ObservationDefinition. Multiple results allowed for observations conforming to this ObservationDefinition. The body structure on the subject's body where the observation is to be made. The method or technique used to perform the observation. The kind of specimen that this type of observation is produced on. The measurement model of device or actual device used to produce observations of this type. The preferred name to be used when reporting the results of observations conforming to this ObservationDefinition. Units allowed for the valueQuantity element in the instance observations conforming to this ObservationDefinition. A set of qualified values associated with a context and a set of conditions - provides a range for quantitative and ordinal observations and a collection of value sets for qualitative observations. This ObservationDefinition defines 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. Some observations have multiple component observations, expressed as separate code value pairs. Set of definitional characteristics for a kind of observation or measurement produced or consumed by an orderable health care service. A concept defining the context for this set of qualified values. The target population this set of qualified values applies to. The sex parameter for clinical use this set of qualified values applies to. The age range this set of qualified values applies to. The gestational age this set of qualified values applies to. Description of the criterion for which the qualified value is valid. The category of range of values for continuous or ordinal observations that match the criteria of this set of qualified values. The range of values defined for continuous or ordinal observations that match the criteria of this set of qualified values. The set of valid coded results for qualitative observations that match the criteria of this set of qualified values. The set of normal coded results for qualitative observations that match the criteria of this set of qualified values. The set of abnormal coded results for qualitative observations that match the criteria of this set of qualified values. The set of critical coded results for qualitative observations that match the criteria of this set of qualified values. The expected coded interpretation values of an observation that matches this qualified interval. For example, high, low, normal. Set of definitional characteristics for a kind of observation or measurement produced or consumed by an orderable health care service. Describes what will be observed.
