RiskAssessment - FHIR v1.1.0

GAO Ballot Package

This page is part of the FHIR Specification (v1.1.0: STU 3 Ballot 1). The current version which supercedes this version is 5.0.0. For a full list of available versions, see the Directory of published versions . Page versions: R5 R4B R4 R3 R2

This is a frozen snapshot of the FHIR specification created for the purpose of balloting the GAO implementation Guide. It includes draft changes that may be part of the future DSTU 2.1 release but further change is expected. Readers should focus solely on the GAO implementation content, and FHIR DSTU 2 for other purposes.

4.13.8 Resource RiskAssessment - Detailed Descriptions

Detailed Descriptions for the elements in the RiskAssessment resource.

RiskAssessment
Definition	An assessment of the likely outcome(s) for a patient or other subject as well as the likelihood of each outcome.
Control	1..1
Alternate Names	Prognosis
RiskAssessment.subject
Definition	The patient or group the risk assessment applies to.
Control	0..1
Type	Reference(Patient \| Group)
Summary	true
To Do	Should this cover anything else? Device? Location?
RiskAssessment.date
Definition	The date (and possibly time) the risk assessment was performed.
Control	0..1
Type	dateTime
Requirements	The assessment results lose validity the more time elapses from when they are first made.
Summary	true
RiskAssessment.condition
Definition	For assessments or prognosis specific to a particular condition, indicates the condition being assessed.
Control	0..1
Type	Reference(Condition)
Summary	true
RiskAssessment.encounter
Definition	The encounter where the assessment was performed.
Control	0..1
Type	Reference(Encounter)
Summary	true
RiskAssessment.performer
Definition	The provider or software application that performed the assessment.
Control	0..1
Type	Reference(Practitioner \| Device)
Summary	true
RiskAssessment.identifier
Definition	Business identifier assigned to the risk assessment.
Note	This is a business identifer, not a resource identifier (see discussion)
Control	0..1
Type	Identifier
Summary	true
RiskAssessment.method
Definition	The algorithm, process or mechanism used to evaluate the risk.
Control	0..1
Binding	RiskAssessmentMethod: The mechanism or algorithm used to make the assessment; e.g. TIMI, PRISM, Cardiff Type 2 diabetes, etc.
Type	CodeableConcept
Requirements	The method can influence the results of the assessment.
Summary	true
To Do	Is this in the 80%?
RiskAssessment.basis
Definition	Indicates the source data considered as part of the assessment (FamilyHistory, Observations, Procedures, Conditions, etc.).
Control	0..*
Type	Reference(Any)
RiskAssessment.prediction
Definition	Describes the expected outcome for the subject.
Control	0..*
Comments	Multiple repetitions can be used to identify the same type of outcome in different timeframes as well as different types of outcomes.
RiskAssessment.prediction.outcome
Definition	One of the potential outcomes for the patient (e.g. remission, death, a particular condition).
Control	1..1
Binding	RiskAssessmentOutcome: The condition or other outcome; e.g. death, remission, amputation, infection, etc.
Type	CodeableConcept
RiskAssessment.prediction.probability[x]
Definition	How likely is the outcome (in the specified timeframe).
Control	0..1
Binding	Risk Probability: The likelihood of the occurrence of a specified outcome (Example)
Type	decimal\|Range\|CodeableConcept
[x] Note	See Choice of Data Types for further information about how to use [x]
Comments	If range is used, it represents the lower and upper bounds of certainty; e.g. 40-60% Decimal values are expressed as percentages as well (max = 100).
Invariants	Defined on this element ras-1: low and high must be percentages, if present (expression: (low.empty() or ((low.code = "%") and (low.system = %ucum))) and (high.empty() or ((high.code = "%") and (high.system = %ucum))), xpath: (not(f:low) or f:low[f:code/@value='%' and f:system/@value='http://unitsofmeasure.org']) and (not(f:high) or f:high[f:code/@value='%' and f:system/@value='http://unitsofmeasure.org'])) ras-2: Must be <= 100 (expression: probabilityDecimal <= 100, xpath: @value <= 100)
RiskAssessment.prediction.relativeRisk
Definition	Indicates the risk for this particular subject (with their specific characteristics) divided by the risk of the population in general. (Numbers greater than 1 = higher risk than the population, numbers less than 1 = lower risk.).
Control	0..1
Type	decimal
Requirements	Absolute risk is less meaningful than relative risk.
To Do	Is this in the 80%?
RiskAssessment.prediction.when[x]
Definition	Indicates the period of time or age range of the subject to which the specified probability applies.
Control	0..1
Type	Period\|Range
[x] Note	See Choice of Data Types for further information about how to use [x]
Comments	If not specified, the risk applies "over the subject's lifespan".
RiskAssessment.prediction.rationale
Definition	Additional information explaining the basis for the prediction.
Control	0..1
Type	string
RiskAssessment.mitigation
Definition	A description of the steps that might be taken to reduce the identified risk(s).
Control	0..1
Type	string
Requirements	One of the main reasons for assessing risks is to identify whether interventional steps are needed to reduce risk.
