A logical model showing the elements of a Symptom that have been deemed important and relevant for capture and exchange.
Symptom Logical Model mapping to Symptom Observation
This table maps the Symptom Observation elements to the Symptom Logical Model
All FHIR elements must have a @value or children
hasValue() or (children().count() > id.count())
Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
Extensions are always sliced by (at least) url
Additional content defined by implementations
May be used to represent additional information that is not part of the basic definition of the element. 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.
Must have either extensions or value[x], not both
exists(f:extension)!=exists(f:*[starts-with(local-name(.), "value")])
A unique string that identifies this instance of a symptom
Whether the symptom is present or absent
The patient who is experiencing the symptom
The person who is reporting the symptom information
Textual description of symptom as provided by patient or care team member
Where the patient feels the symptom in the body.
Other symptoms associated with this symptom
Extensions that cannot be ignored even if unrecognized
May be used to represent additional information that is not part of the basic definition of the element and that modifies the understanding of the element in which it is contained 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 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](http://hl7.org/fhir/R4/extensibility.html#modifierExtension).
Modifier extensions are expected to modify the meaning or interpretation of the element that contains them
The patient's internal perception of the symptom.
Textual description of the symptom quality
Code for the specific scale or assessment (if any) used to determine the quality
Code that represents the symptom quality
The intensity with which the patient experiences the symptom.
Textual description of the symptom severity
Code for the specific scale or assessment if any used to determine the severity
Code that represents the symptom severity
How the symptom affects the patient's daily activities.
Code for the specific scale or assessment (if any) used to determine the impact
Code that represents the functional impact
Emotional or mental impact of a symptom.
Code that represents the affective grade
What was occurring at the time of symptom onset.
Patient reported actions, conditions, events, physical objects or other factors that initiate or worsen symptoms or the condition of interest (pain, nausea, dyspnea, dizziness, or other).
Medication that triggers or exacerbates the symptom
Information given about actions, conditions, events, or other factors
Patient-reported actions, conditions, events, or other factors that decrease the symptoms or condition
Patient-reported actions that were occuring at time of symptom onset
How often the patient experiences the symptom i.e. expressed as 3x/day or 2x/week.
Timing includes the actual or estimated date/time of onset, character of onset, how often the patient experiences the symptom, and the length of time the symptom persists.
The rate at which a physiological symptom became apparent.
Clinically relevant time or period for the symptom since first occurance.
The length of time the symptom persists in this instance of occurance.
Term to represent both the course and onset of a disease. Many conditions with an acute (sudden) onset also have an acute (short duration) course.
Whether a condition is improving, worsening, stable, or resolved.
Non clinical information about the symptom
The date the symptom was entered, edited, or deleted.
Date/time when the current version was made available.
