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.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.basedOn
Definition	A reference to the request that is fulfilled by this risk assessment.
Control	0..1
Type	Reference ( Any )
RiskAssessment.parent
Definition	A reference to a resource that this risk assessment is part of, such as a Procedure.
Control	0..1
Type	Reference ( Any )
RiskAssessment.status
Definition	The status of the RiskAssessment, using the same statuses as an Observation.
Control	1..1
Terminology Binding	ObservationStatus ( Required )
Type	code
RiskAssessment.code

Control	0..1
Type	Reference ( Patient \| Group )
Summary	true
To Do	Should this cover anything else? Device? Location?
RiskAssessment.context
Definition	The encounter where the assessment was performed.
Control	0..1
Type	Reference ( Encounter \| EpisodeOfCare )
Summary	true
RiskAssessment.occurrence[x]
Definition	The date (and possibly time) the risk assessment was performed.
Control	0..1
Type	dateTime \| Period
[x] Note	See Choice of Data Types for further information about how to use [x]
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.performer
Definition	The provider or software application that performed the assessment.
Control	0..1
Type	Reference ( Practitioner \| Device )
Summary	true
RiskAssessment.reason[x]
Definition	The reason the risk assessment was performed.
Control	0..1
Type	CodeableConcept \| Reference ( Any )
[x] Note	See Choice of Data Types for further information about how to use [x]
RiskAssessment.method
Definition	The algorithm, process or mechanism used to evaluate the risk.
Control	0..1
Terminology Binding	RiskAssessmentMethod :
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.
Invariants	Defined on this element ras-2 : Must be <= 100 ( expression : probability is decimal implies probability.as(decimal) <= 100, xpath: not(f:probabilityDecimal) or f:probabilityDecimal/@value <= 100)
RiskAssessment.prediction.outcome
Definition	One of the potential outcomes for the patient (e.g. remission, death, a particular condition).
Control	1..1
Terminology Binding	RiskAssessmentOutcome :
Type	CodeableConcept
RiskAssessment.prediction.probability[x]
Definition	How likely is the outcome (in the specified timeframe).
Control	0..1
Terminology Binding	Risk Probability ( 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']))
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.
RiskAssessment.note
Definition	Additional comments about the risk assessment.
Control	0..1
