Definition

Indicates the source data considered as part of the assessment (FamilyHistory, Observations, Procedures, Conditions, etc.).

Control0..*
TypeReference(Any)
RiskAssessment.prediction
Definition

Describes the expected outcome for the subject.

Control0..*
Comments

Multiple repetitions can be used to identify the same type of outcome in different timeframes as well as different types of outcomes.

InvariantsDefined 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).

Control1..1
Terminology BindingRiskAssessmentOutcome:
TypeCodeableConcept
RiskAssessment.prediction.probability[x]
Definition

How likely is the outcome (in the specified timeframe).

Control0..1
Terminology BindingRisk Probability (Example)
Typedecimal|Range|CodeableConcept
[x] NoteSee 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).

InvariantsDefined 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.).

Control0..1
Typedecimal
Requirements

Absolute risk is less meaningful than relative risk.

To DoIs 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.

Control0..1
TypePeriod|Range
[x] NoteSee Choice of Data Types for further information about how to use [x]
Comments

If not specified, the risk applies "over the subject's lifespan".

Control0..1
Typestring
RiskAssessment.mitigation
Definition

A description of the steps that might be taken to reduce the identified risk(s).

Control0..1
Typestring
Requirements

One of the main reasons for assessing risks is to identify whether interventional steps are needed to reduce risk.

RiskAssessment.note
