OrthelligentFitIndexReport (DiagnosticReport)
The OrthelligentFitIndexReport is the actual payload of the data export bundle. It contains all measurement values with Orthelligent up to the export date.
Each tuple of a measurement value (OrthelligentTestResult) and a corresponding reference value (analogous measurement of the healthy body site, for instance, a historical reference value, or a fixed reference value) forms a test Fit Index (OrthelligentTestFitIndex).
All Fit Indices of a category result in a category Fit Index (OrthelligentCategoryFitIndex). The category Fit Indices are the basis for the overall Fit Index (OrthelligentFitIndex).
The OrthelligentFitIndexReport contains these data sets in a tree structure:
- OrthelligentFitIndex (result: Observation)
- Overall Fit Index value (value)
- Included category Fit Indices (derivedFrom: Observation)
- Category Fit Index value (value)
- Included test Fit Indices (derivedFrom: Observation)
- Test Fit Index value (value)
- Included test results (derivedFrom: Observation)
- Test result description (code)
- OrthelligentPatient (subject)
- Test timestamp (effective)
- Measurement value (value)
- Additional information/calculation data (component)
- Affected/measured body part (bodySite)
- Test type (e.g. sensor-based measurement) (method)
- Sensor ID or S/N (optional) (device)
- Comments on test execution (note)
- Pain value (0..10) during test (component)

DiagnosticReport | I | DiagnosticReport | There are no (further) constraints on this element Element idDiagnosticReport A Diagnostic report - a combination of request information, atomic results, images, interpretation, as well as formatted reports Alternate namesReport, Test, Result, Results, Labs, Laboratory DefinitionThe findings and interpretation of diagnostic tests performed on patients, groups of patients, devices, and locations, and/or specimens derived from these. The report includes clinical context such as requesting and provider information, and some mix of atomic results, images, textual and coded interpretations, and formatted representation of diagnostic reports. This is intended to capture a single report and is not suitable for use in displaying summary information that covers multiple reports. For example, this resource has not been designed for laboratory cumulative reporting formats nor detailed structured reports for sequencing.
| |
id | Σ | 0..1 | string | There are no (further) constraints on this element Element idDiagnosticReport.id Logical id of this artifact DefinitionThe logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes. The only time that a resource does not have an id is when it is being submitted to the server using a create operation. |
meta | Σ | 0..1 | Meta | There are no (further) constraints on this element Element idDiagnosticReport.meta Metadata about the resource DefinitionThe 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 | Σ ?! | 0..1 | uri | There are no (further) constraints on this element Element idDiagnosticReport.implicitRules A set of rules under which this content was created DefinitionA 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. Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element. Often, when used, the URL is a reference to an implementation guide that defines these special rules as part of it's narrative along with other profiles, value sets, etc.
|
language | 0..1 | codeBinding | There are no (further) constraints on this element Element idDiagnosticReport.language Language of the resource content DefinitionThe base language in which the resource is written. Language is provided to support indexing and accessibility (typically, services such as text to speech use the language tag). The html language tag in the narrative applies to the narrative. The language tag on the resource may be used to specify the language of other presentations generated from the data in the resource. Not all the content has to be in the base language. The Resource.language should not be assumed to apply to the narrative automatically. If a language is specified, it should it also be specified on the div element in the html (see rules in HTML5 for information about the relationship between xml:lang and the html lang attribute). A human language.
| |
text | 0..1 | Narrative | There are no (further) constraints on this element Element idDiagnosticReport.text Text summary of the resource, for human interpretation Alternate namesnarrative, html, xhtml, display DefinitionA 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 resources do not have narrative. Resources that are not contained SHOULD have a narrative. In some cases, a resource may only have text with little or no additional discrete data (as long as all minOccurs=1 elements are satisfied). This may be necessary for data from legacy systems where information is captured as a "text blob" or where text is additionally entered raw or narrated and encoded information is added later.
| |
contained | 0..* | Resource | There are no (further) constraints on this element Element idDiagnosticReport.contained Contained, inline Resources Alternate namesinline resources, anonymous resources, contained resources DefinitionThese 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. This should never be done when the content can be identified properly, as once identification is lost, it is extremely difficult (and context dependent) to restore it again. Contained resources may have profiles and tags In their meta elements, but SHALL NOT have security labels.

extension | I | 0..* | Extension | There are no (further) constraints on this element Element idDiagnosticReport.extension Additional content defined by implementations Alternate namesextensions, user content DefinitionMay 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. There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone. Unordered, Open, by url(Value) Extensions are always sliced by (at least) url Constraints

modifierExtension | ?! I | 0..* | Extension | There are no (further) constraints on this element Element idDiagnosticReport.modifierExtension Extensions that cannot be ignored Alternate namesextensions, user content DefinitionMay 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). Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions. There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

basedOn | S I | 1..1 | Reference(OrthelligentTreatment) | Element idDiagnosticReport.basedOn Orthelligent Treatment (CarePlan) Alternate namesRequest DefinitionThe Orthelligent Treatment (CarePlan) in the context of which this overall fit index has been reached by the Patient. This allows tracing of authorization for the report and tracking whether proposals/recommendations were acted upon. Note: Usually there is one test request for each result, however in some circumstances multiple test requests may be represented using a single test result resource. Note that there are also cases where one request leads to multiple reports. Reference(OrthelligentTreatment) Constraints
|
status | Σ ?! | 1..1 | codeBinding | There are no (further) constraints on this element Element idDiagnosticReport.status registered | partial | preliminary | final + DefinitionThe status of the diagnostic report. Diagnostic services routinely issue provisional/incomplete reports, and sometimes withdraw previously released reports. Note that FHIR strings SHALL NOT exceed 1MB in size The status of the diagnostic report.
|
category | Σ | 0..* | CodeableConcept | There are no (further) constraints on this element Element idDiagnosticReport.category Service category Alternate namesDepartment, Sub-department, Service, Discipline DefinitionA code that classifies the clinical discipline, department or diagnostic service that created the report (e.g. cardiology, biochemistry, hematology, MRI). This is used for searching, sorting and display purposes. Multiple categories are allowed using various categorization schemes. The level of granularity is defined by the category concepts in the value set. More fine-grained filtering can be performed using the metadata and/or terminology hierarchy in DiagnosticReport.code. Codes for diagnostic service sections.
|
code | Σ | 1..1 | CodeableConceptBinding | There are no (further) constraints on this element Element idDiagnosticReport.code Name/Code for this diagnostic report Alternate namesType DefinitionA code or name that describes this diagnostic report. Not all terminology uses fit this general pattern. In some cases, models should not use CodeableConcept and use Coding directly and provide their own structure for managing text, codings, translations and the relationship between elements and pre- and post-coordination. Codes that describe Diagnostic Reports.

subject | Σ I | 0..1 | Reference(Patient | Group | Device | Location) | Element idDiagnosticReport.subject The Orthelligent Patient Alternate namesPatient DefinitionThe subject of the report. This is a user of Orthelligent Knee, i.e. the Orthelligent Patient. SHALL know the subject context. References SHALL be a reference to an actual FHIR resource, and SHALL be resolveable (allowing for access control, temporary unavailability, etc.). Resolution can be either by retrieval from the URL, or, where applicable by resource type, by treating an absolute reference as a canonical URL and looking it up in a local registry/repository. Reference(Patient | Group | Device | Location) Constraints
|
encounter | Σ I | 0..1 | Reference(Encounter) | There are no (further) constraints on this element Element idDiagnosticReport.encounter Health care event when test ordered Alternate namesContext DefinitionThe healthcare event (e.g. a patient and healthcare provider interaction) which this DiagnosticReport is about. Links the request to the Encounter context. This will typically be the encounter the event occurred within, but some events may be initiated prior to or after the official completion of an encounter but still be tied to the context of the encounter (e.g. pre-admission laboratory tests).
|
effective[x] | Σ | 0..1 | There are no (further) constraints on this element Element idDiagnosticReport.effective[x] Clinically relevant time/time-period for report Alternate namesObservation time, Effective Time, Occurrence DefinitionThe time or time-period the observed values are related to. When the subject of the report is a patient, this is usually either the time of the procedure or of specimen collection(s), but very often the source of the date/time is not known, only the date/time itself. Need to know where in the patient history to file/present this report. If the diagnostic procedure was performed on the patient, this is the time it was performed. If there are specimens, the diagnostically relevant time can be derived from the specimen collection times, but the specimen information is not always available, and the exact relationship between the specimens and the diagnostically relevant time is not always automatic.

effectivePeriod | Period | There are no (further) constraints on this element Data type | ||
issued | Σ | 0..1 | instant | There are no (further) constraints on this element Element idDiagnosticReport.issued DateTime this version was made Alternate namesDate published, Date Issued, Date Verified DefinitionThe date and time that this version of the report was made available to providers, typically after the report was reviewed and verified. Clinicians need to be able to check the date that the report was released. May be different from the update time of the resource itself, because that is the status of the record (potentially a secondary copy), not the actual release time of the report.
|
performer | Σ I | 0..* | Reference(Practitioner | PractitionerRole | Organization | CareTeam) | There are no (further) constraints on this element Element idDiagnosticReport.performer Responsible Diagnostic Service Alternate namesLaboratory, Service, Practitioner, Department, Company, Authorized by, Director DefinitionThe diagnostic service that is responsible for issuing the report. Need to know whom to contact if there are queries about the results. Also may need to track the source of reports for secondary data analysis. This is not necessarily the source of the atomic data items or the entity that interpreted the results. It is the entity that takes responsibility for the clinical report.

specimen | I | 0..* | Reference(Specimen) | There are no (further) constraints on this element Element idDiagnosticReport.specimen Specimens this report is based on DefinitionDetails about the specimens on which this diagnostic report is based. Need to be able to report information about the collected specimens on which the report is based. If the specimen is sufficiently specified with a code in the test result name, then this additional data may be redundant. If there are multiple specimens, these may be represented per observation or group.

imagingStudy | I | 0..* | Reference(ImagingStudy) | There are no (further) constraints on this element Element idDiagnosticReport.imagingStudy Reference to full details of imaging associated with the diagnostic report DefinitionOne or more links to full details of any imaging performed during the diagnostic investigation. Typically, this is imaging performed by DICOM enabled modalities, but this is not required. A fully enabled PACS viewer can use this information to provide views of the source images. ImagingStudy and the image element are somewhat overlapping - typically, the list of image references in the image element will also be found in one of the imaging study resources. However, each caters to different types of displays for different types of purposes. Neither, either, or both may be provided.

Need to track the status of individual results. Some results are finalized before the whole report is finalized. This element is labeled as a modifier because the status contains codes that mark the resource as not currently valid. Codes providing the status of an observation.
|
category | S | 0..* | CodeableConceptBinding | Element idObservation.category Classification of type of fit index DefinitionA code that classifies the type of fit index: overall fit index, category fit index, or test fit index. Used for filtering what observations are retrieved and displayed. In addition to the required category valueset, this element allows various categorization schemes based on the owner’s definition of the category and effectively multiple categories can be used at once. The level of granularity is defined by the category concepts in the value set. Codes for high level observation categories.
|
code | Σ | 1..1 | CodeableConcept | There are no (further) constraints on this element Element idObservation.code Type of observation (code / type) Alternate namesName DefinitionDescribes what was observed. Sometimes this is called the observation "name". Knowing what kind of observation is being made is essential to understanding the observation. All code-value and, if present, component.code-component.value pairs need to be taken into account to correctly understand the meaning of the observation. Codes identifying names of simple observations.

subject | Σ I | 0..1 | Reference(Patient | Group | Device | Location) | There are no (further) constraints on this element Element idObservation.subject Who and/or what the observation is about DefinitionThe 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 Observations have no value if you don't know who or what they're about. One would expect this element to be a cardinality of 1..1. The only circumstance in which the subject can be missing is when the observation is made by a device that does not know the patient. In this case, the observation SHALL be matched to a patient through some context/channel matching technique, and at this point, the observation should be updated. Reference(Patient | Group | Device | Location) Constraints
|
focus | Σ I | 0..* | Reference(Resource) | There are no (further) constraints on this element Element idObservation.focus What the observation is about, when it is not about the subject of record DefinitionThe 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. Typically, an observation is made about the subject - a patient, or group of patients, location, or device - and the distinction between the subject and what is directly measured for an observation is specified in the observation code itself ( e.g., "Blood Glucose") and does not need to be represented separately using this element.

encounter | Σ I | 0..1 | Reference(Encounter) | There are no (further) constraints on this element Element idObservation.encounter Healthcare event during which this observation is made Alternate namesContext DefinitionThe healthcare event (e.g. a patient and healthcare provider interaction) during which this observation is made. For some observations it may be important to know the link between an observation and a particular encounter. This will typically be the encounter the event occurred within, but some events may be initiated prior to or after the official completion of an encounter but still be tied to the context of the encounter (e.g. pre-admission laboratory tests).

effective[x] | Σ | 0..1 | There are no (further) constraints on this element Element idObservation.effective[x] Clinically relevant time/time-period for observation Alternate namesOccurrence DefinitionThe 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. Knowing when an observation was deemed true is important to its relevance as well as determining trends. At least a date should be present unless this observation is a historical report. For recording imprecise or "fuzzy" times (For example, a blood glucose measurement taken "after breakfast") use the Timing datatype which allow the measurement to be tied to regular life events.

value[x] | S Σ I | 1..1 | Element idObservation.value[x] FitIndex (percentage value) DefinitionThis is fit index value of the respective measurement:
An observation exists to have a value, though it might not if it is in error, or if it represents a group of observations. An observation may have; 1) a single value here, 2) both a value and a set of related or component values, or 3) only a set of related or component values. If a value is present, the datatype for this element should be determined by Observation.code. A CodeableConcept with just a text would be used instead of a string if the field was usually coded, or if the type associated with the Observation.code defines a coded value. For additional guidance, see the Notes section below.

dataAbsentReason | I | 0..1 | CodeableConceptBinding | There are no (further) constraints on this element Element idObservation.dataAbsentReason Why the result is missing DefinitionProvides a reason why the expected value in the element Observation.value[x] is missing. For many results it is necessary to handle exceptional values in measurements. Null or exceptional values can be represented two ways in FHIR Observations. One way is to simply include them in the value set and represent the exceptions in the value. For example, measurement values for a serology test could be "detected", "not detected", "inconclusive", or "specimen unsatisfactory". The alternate way is to use the value element for actual observations and use the explicit dataAbsentReason element to record exceptional values. For example, the dataAbsentReason code "error" could be used when the measurement was not completed. Note that an observation may only be reported if there are values to report. For example differential cell counts values may be reported only when > 0. Because of these options, use-case agreements are required to interpret general observations for null or exceptional values.

Historically used for laboratory results (known as 'abnormal flag' ), its use extends to other use cases where coded interpretations are relevant. Often reported as one or more simple compact codes this element is often placed adjacent to the result value in reports and flow sheets to signal the meaning/normalcy status of the result.

Need to be able to provide multiple reference ranges for different contexts. Most observations only have one generic reference range. Systems MAY choose to restrict to only supplying the relevant reference range based on knowledge about the patient (e.g., specific to the patient's age, gender, weight and other factors), but this might not be possible or appropriate. Whenever more than one reference range is supplied, the differences between them SHOULD be provided in the reference range and/or age properties.

Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc. Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element.

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 resources do not have narrative. Resources that are not contained SHOULD have a narrative. In some cases, a resource may only have text with little or no additional discrete data (as long as all minOccurs=1 elements are satisfied). This may be necessary for data from legacy systems where information is captured as a "text blob" or where text is additionally entered raw or narrated and encoded information is added later.

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. Typically, an observation is made about the subject - a patient, or group of patients, location, or device - and the distinction between the subject and what is directly measured for an observation is specified in the observation code itself ( e.g., "Blood Glucose") and does not need to be represented separately using this element.

encounter | Σ I | 0..1 | Reference(Encounter) | There are no (further) constraints on this element Element idObservation.encounter Healthcare event during which this observation is made Alternate namesContext DefinitionThe healthcare event (e.g. a patient and healthcare provider interaction) during which this observation is made. For some observations it may be important to know the link between an observation and a particular encounter. This will typically be the encounter the event occurred within, but some events may be initiated prior to or after the official completion of an encounter but still be tied to the context of the encounter (e.g. pre-admission laboratory tests).

effective[x] | Σ | 0..1 | There are no (further) constraints on this element Element idObservation.effective[x] Clinically relevant time/time-period for observation Alternate namesOccurrence DefinitionThe 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. Knowing when an observation was deemed true is important to its relevance as well as determining trends. At least a date should be present unless this observation is a historical report. For recording imprecise or "fuzzy" times (For example, a blood glucose measurement taken "after breakfast") use the Timing datatype which allow the measurement to be tied to regular life events.

value[x] | S Σ I | 1..1 | There are no (further) constraints on this element Element idObservation.value[x] FitIndex (percentage value) DefinitionThis is fit index value of the respective measurement:
An observation exists to have a value, though it might not if it is in error, or if it represents a group of observations. An observation may have; 1) a single value here, 2) both a value and a set of related or component values, or 3) only a set of related or component values. If a value is present, the datatype for this element should be determined by Observation.code. A CodeableConcept with just a text would be used instead of a string if the field was usually coded, or if the type associated with the Observation.code defines a coded value. For additional guidance, see the Notes section below.

dataAbsentReason | I | 0..1 | CodeableConceptBinding | There are no (further) constraints on this element Element idObservation.dataAbsentReason Why the result is missing DefinitionProvides a reason why the expected value in the element Observation.value[x] is missing. For many results it is necessary to handle exceptional values in measurements. Null or exceptional values can be represented two ways in FHIR Observations. One way is to simply include them in the value set and represent the exceptions in the value. For example, measurement values for a serology test could be "detected", "not detected", "inconclusive", or "specimen unsatisfactory". The alternate way is to use the value element for actual observations and use the explicit dataAbsentReason element to record exceptional values. For example, the dataAbsentReason code "error" could be used when the measurement was not completed. Note that an observation may only be reported if there are values to report. For example differential cell counts values may be reported only when > 0. Because of these options, use-case agreements are required to interpret general observations for null or exceptional values.

Need to be able to provide multiple reference ranges for different contexts. Most observations only have one generic reference range. Systems MAY choose to restrict to only supplying the relevant reference range based on knowledge about the patient (e.g., specific to the patient's age, gender, weight and other factors), but this might not be possible or appropriate.

Resource definitions may define what content should be represented in the narrative to ensure clinical safety. Contained resources do not have narrative. Resources that are not contained SHOULD have a narrative. In some cases, a resource may only have text with little or no additional discrete data (as long as all minOccurs=1 elements are satisfied). This may be necessary for data from legacy systems where information is captured as a "text blob" or where text is additionally entered raw or narrated and encoded information is added later.

code | Σ | 1..1 | CodeableConcept | There are no (further) constraints on this element Element idObservation.code Type of observation (code / type) Alternate namesName DefinitionDescribes what was observed. Sometimes this is called the observation "name". Knowing what kind of observation is being made is essential to understanding the observation. All code-value and, if present, component.code-component.value pairs need to be taken into account to correctly understand the meaning of the observation. Codes identifying names of simple observations.

subject | Σ I | 0..1 | Reference(Patient | Group | Device | Location) | There are no (further) constraints on this element Element idObservation.subject Who and/or what the observation is about DefinitionThe 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 Observations have no value if you don't know who or what they're about. One would expect this element to be a cardinality of 1..1. The only circumstance in which the subject can be missing is when the observation is made by a device that does not know the patient. In this case, the observation SHALL be matched to a patient through some context/channel matching technique, and at this point, the observation should be updated. Reference(Patient | Group | Device | Location) Constraints
|
focus | Σ I | 0..* | Reference(Resource) | There are no (further) constraints on this element Element idObservation.focus What the observation is about, when it is not about the subject of record DefinitionThe 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. Typically, an observation is made about the subject - a patient, or group of patients, location, or device - and the distinction between the subject and what is directly measured for an observation is specified in the observation code itself ( e.g., "Blood Glucose") and does not need to be represented separately using this element.

encounter | Σ I | 0..1 | Reference(Encounter) | There are no (further) constraints on this element Element idObservation.encounter Healthcare event during which this observation is made Alternate namesContext DefinitionThe healthcare event (e.g. a patient and healthcare provider interaction) during which this observation is made. For some observations it may be important to know the link between an observation and a particular encounter. This will typically be the encounter the event occurred within, but some events may be initiated prior to or after the official completion of an encounter but still be tied to the context of the encounter (e.g. pre-admission laboratory tests).
|
effective[x] | Σ | 0..1 | There are no (further) constraints on this element Element idObservation.effective[x] Clinically relevant time/time-period for observation Alternate namesOccurrence DefinitionThe 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. Knowing when an observation was deemed true is important to its relevance as well as determining trends. At least a date should be present unless this observation is a historical report. For recording imprecise or "fuzzy" times (For example, a blood glucose measurement taken "after breakfast") use the Timing datatype which allow the measurement to be tied to regular life events.

May give a degree of confidence in the observation and also indicates where follow-up questions should be directed. References SHALL be a reference to an actual FHIR resource, and SHALL be resolveable (allowing for access control, temporary unavailability, etc.). Resolution can be either by retrieval from the URL, or, where applicable by resource type, by treating an absolute reference as a canonical URL and looking it up in a local registry/repository.

value[x] | S Σ I | 1..1 | There are no (further) constraints on this element Element idObservation.value[x] FitIndex (percentage value) DefinitionThis is fit index value of the respective measurement:
An observation exists to have a value, though it might not if it is in error, or if it represents a group of observations. An observation may have; 1) a single value here, 2) both a value and a set of related or component values, or 3) only a set of related or component values. If a value is present, the datatype for this element should be determined by Observation.code. A CodeableConcept with just a text would be used instead of a string if the field was usually coded, or if the type associated with the Observation.code defines a coded value. For additional guidance, see the Notes section below.

dataAbsentReason | I | 0..1 | CodeableConceptBinding | There are no (further) constraints on this element Element idObservation.dataAbsentReason Why the result is missing DefinitionProvides a reason why the expected value in the element Observation.value[x] is missing. For many results it is necessary to handle exceptional values in measurements. Null or exceptional values can be represented two ways in FHIR Observations. One way is to simply include them in the value set and represent the exceptions in the value. For example, measurement values for a serology test could be "detected", "not detected", "inconclusive", or "specimen unsatisfactory". The alternate way is to use the value element for actual observations and use the explicit dataAbsentReason element to record exceptional values. For example, the dataAbsentReason code "error" could be used when the measurement was not completed. Note that an observation may only be reported if there are values to report. For example differential cell counts values may be reported only when > 0. Because of these options, use-case agreements are required to interpret general observations for null or exceptional values.

interpretation | 0..* | CodeableConceptBinding | There are no (further) constraints on this element Element idObservation.interpretation High, low, normal, etc. Alternate namesAbnormal Flag DefinitionA categorical assessment of an observation value. For example, high, low, normal. For some results, particularly numeric results, an interpretation is necessary to fully understand the significance of a result. Historically used for laboratory results (known as 'abnormal flag' ), its use extends to other use cases where coded interpretations are relevant. Often reported as one or more simple compact codes this element is often placed adjacent to the result value in reports and flow sheets to signal the meaning/normalcy status of the result. Codes identifying interpretations of observations.

Only used if not implicit in code found in Observation.code. In many systems, this may be represented as a related observation instead of an inline component. If the use case requires BodySite to be handled as a separate resource (e.g. to identify and track separately) then use the standard extension bodySite. Codes describing anatomical locations. May include laterality.

referenceRange | I | 0..* | BackboneElement | There are no (further) constraints on this element Element idObservation.referenceRange Provides guide for interpretation DefinitionGuidance 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 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. Most observations only have one generic reference range. Systems MAY choose to restrict to only supplying the relevant reference range based on knowledge about the patient (e.g., specific to the patient's age, gender, weight and other factors), but this might not be possible or appropriate. Whenever more than one reference range is supplied, the differences between them SHOULD be provided in the reference range and/or age properties.

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 can 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). Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions. There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions.

low | I | 0..1 | SimpleQuantity | There are no (further) constraints on this element Element idObservation.referenceRange.low Low Range, if relevant DefinitionThe value of the low bound of the reference range. The low bound of the reference range endpoint is inclusive of the value (e.g. reference range is >=5 - <=9). If the low bound is omitted, it is assumed to be meaningless (e.g. reference range is <=2.3). The context of use may frequently define what kind of quantity this is and therefore what kind of units can be used. The context of use may also restrict the values for the comparator.

high | I | 0..1 | SimpleQuantity | There are no (further) constraints on this element Element idObservation.referenceRange.high High Range, if relevant DefinitionThe value of the high bound of the reference range. The high bound of the reference range endpoint is inclusive of the value (e.g. reference range is >=5 - <=9). If the high bound is omitted, it is assumed to be meaningless (e.g. reference range is >= 2.3). The context of use may frequently define what kind of quantity this is and therefore what kind of units can be used. The context of use may also restrict the values for the comparator.

This is a neonatal age (e.g. number of weeks at term) if the meaning says so. Some analytes vary greatly over age. The stated low and high value are assumed to have arbitrarily high precision when it comes to determining which values are in the range. I.e. 1.99 is not in the range 2 -> 3.

When using this element, an observation will typically have either a value or a set of related resources, although both may be present in some cases. For a discussion on the ways Observations can assembled in groups together, see Notes below. Note that a system may calculate results from QuestionnaireResponse into a final score and represent the score as an Observation.

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. For a discussion on the ways Observations can be assembled in groups together see Notes below.

An observation exists to have a value, though it might not if it is in error, or if it represents a group of observations. Used when observation has a set of component observations. An observation may have both a value (e.g. an Apgar score) and component observations (the observations from which the Apgar score was derived).

Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc. Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element. Often, when used, the URL is a reference to an implementation guide that defines these special rules as part of it's narrative along with other profiles, value sets, etc.

Language is provided to support indexing and accessibility (typically, services such as text to speech use the language tag). The html language tag in the narrative applies to the narrative. The language tag on the resource may be used to specify the language of other presentations generated from the data in the resource. Not all the content has to be in the base language. The Resource.language should not be assumed to apply to the narrative automatically. If a language is specified, it should it also be specified on the div element in the html (see rules in HTML5 for information about the relationship between xml:lang and the html lang attribute). A human language.

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 resources do not have narrative. Resources that are not contained SHOULD have a narrative. In some cases, a resource may only have text with little or no additional discrete data (as long as all minOccurs=1 elements are satisfied). This may be necessary for data from legacy systems where information is captured as a "text blob" or where text is additionally entered raw or narrated and encoded information is added later.

This should never be done when the content can be identified properly, as once identification is lost, it is extremely difficult (and context dependent) to restore it again. Contained resources may have profiles and tags In their meta elements, but SHALL NOT have security labels.

Need to track the status of individual results. Some results are finalized before the whole report is finalized. This element is labeled as a modifier because the status contains codes that mark the resource as not currently valid. Codes providing the status of an observation.

In addition to the required category valueset, this element allows various categorization schemes based on the owner’s definition of the category and effectively multiple categories can be used at once. The level of granularity is defined by the category concepts in the value set. Codes for high level observation categories.

subject | Σ I | 0..1 | Reference(Patient | Group | Device | Location) | There are no (further) constraints on this element Element idObservation.subject Who and/or what the observation is about DefinitionThe 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 Observations have no value if you don't know who or what they're about. One would expect this element to be a cardinality of 1..1. The only circumstance in which the subject can be missing is when the observation is made by a device that does not know the patient. In this case, the observation SHALL be matched to a patient through some context/channel matching technique, and at this point, the observation should be updated. Reference(Patient | Group | Device | Location) Constraints
|
focus | Σ I | 0..* | Reference(Resource) | There are no (further) constraints on this element Element idObservation.focus What the observation is about, when it is not about the subject of record DefinitionThe 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. Typically, an observation is made about the subject - a patient, or group of patients, location, or device - and the distinction between the subject and what is directly measured for an observation is specified in the observation code itself ( e.g., "Blood Glucose") and does not need to be represented separately using this element.

For some observations it may be important to know the link between an observation and a particular encounter. This will typically be the encounter the event occurred within, but some events may be initiated prior to or after the official completion of an encounter but still be tied to the context of the encounter (e.g. pre-admission laboratory tests).

effective[x] | S Σ | 1..1 | There are no (further) constraints on this element Element idObservation.effective[x] Clinically relevant time/time-period for observation Alternate namesOccurrence DefinitionThe 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. Knowing when an observation was deemed true is important to its relevance as well as determining trends. At least a date should be present unless this observation is a historical report. For recording imprecise or "fuzzy" times (For example, a blood glucose measurement taken "after breakfast") use the Timing datatype which allow the measurement to be tied to regular life events.

value[x] | S Σ I | 1..1 | There are no (further) constraints on this element Element idObservation.value[x] Actual result DefinitionThe information determined as a result of making the observation, if the information has a simple value. An observation exists to have a value, though it might not if it is in error, or if it represents a group of observations. An observation may have; 1) a single value here, 2) both a value and a set of related or component values, or 3) only a set of related or component values. If a value is present, the datatype for this element should be determined by Observation.code. A CodeableConcept with just a text would be used instead of a string if the field was usually coded, or if the type associated with the Observation.code defines a coded value.

dataAbsentReason | I | 0..1 | CodeableConceptBinding | There are no (further) constraints on this element Element idObservation.dataAbsentReason Why the result is missing DefinitionProvides a reason why the expected value in the element Observation.value[x] is missing. For many results it is necessary to handle exceptional values in measurements. Null or exceptional values can be represented two ways in FHIR Observations. One way is to simply include them in the value set and represent the exceptions in the value. For example, measurement values for a serology test could be "detected", "not detected", "inconclusive", or "specimen unsatisfactory". The alternate way is to use the value element for actual observations and use the explicit dataAbsentReason element to record exceptional values. For example, the dataAbsentReason code "error" could be used when the measurement was not completed. Note that an observation may only be reported if there are values to report. For example differential cell counts values may be reported only when > 0. Because of these options, use-case agreements are required to interpret general observations for null or exceptional values.

Need to be able to provide multiple reference ranges for different contexts. Most observations only have one generic reference range. Systems MAY choose to restrict to only supplying the relevant reference range based on knowledge about the patient (e.g., specific to the patient's age, gender, weight and other factors), but this might not be possible or appropriate. Whenever more than one reference range is supplied, the differences between them SHOULD be provided in the reference range and/or age properties.
