statusregistered | preliminary | final | amended +The status of the RiskAssessment, using the same statuses as an Observation.
methodEvaluation mechanismThe algorithm, process or mechanism used to evaluate the risk.
codeType of assessmentThe type of the risk assessment performed.

contextWhere was assessment performed?The encounter where the assessment was performed.
occurrence[x]When was assessment made?The date (and possibly time) the risk assessment was performed.
conditionCondition assessedFor assessments or prognosis specific to a particular condition, indicates the condition being assessed.
performerWho did assessment?The provider or software application that performed the assessment.

reasonReferenceWhy the assessment was necessary?Resources supporting the reason the risk assessment was performed.
basisInformation used in assessmentIndicates the source data considered as part of the assessment (for example, FamilyHistory, Observations, Procedures, Conditions, etc.).
predictionOutcome predictedDescribes the expected outcome for the subject.Multiple repetitions can be used to identify the same type of outcome in different timeframes as well as different types of outcomes.
prediction.idUnique id for inter-element referencingUnique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
prediction.extensionAdditional content defined by implementationsMay 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.
prediction.modifierExtensionExtensions that cannot be ignored even if unrecognizedMay 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).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.
prediction.outcomePossible outcome for the subjectOne of the potential outcomes for the patient (e.g. remission, death, a particular condition).
prediction.probability[x]Likelihood of specified outcomeIndicates how likely the outcome is (in the specified timeframe).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).
prediction.qualitativeRiskLikelihood of specified outcome as a qualitative valueIndicates how likely the outcome is (in the specified timeframe), expressed as a qualitative value (e.g. low, medium, or high).
prediction.relativeRiskRelative likelihoodIndicates 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.).
prediction.when[x]Timeframe or age rangeIndicates the period of time or age range of the subject to which the specified probability applies.If not specified, the risk applies "over the subject's lifespan".
prediction.rationaleExplanation of predictionAdditional information explaining the basis for the prediction.
mitigationHow to reduce riskA description of the steps that might be taken to reduce the identified risk(s).
noteComments on the risk assessmentAdditional comments about the risk assessment.

Scope and Usage

This resource is an event resource from a FHIR workflow perspective - see Workflow, specifically Event.

This resource captures predicted outcomes for a patient or population on the basis of source information. Examples include:

This resource can be used to represent the results of formal scoring/decision support tools that evaluate risk. It can also be used to capture a practitioner's subjective assessment of the patient's risk based on existing knowledge and previous experience.

Boundaries and Relationships

Risk assessments are a specialized type of observation. A specialized resource is used to provide a simpler mechanism to capture of a series of risks and to associate those risks with time-ranges, probabilities, etc. All risk assertions are captured at one time based on a single set of source inputs. Capture of a single risk MAY be done using the Observation class, particularly in circumstances where it's treated as a generic observation, but for consistency, all risk assessments and prognosis SHOULD be captured using RiskAssessment.

Risk assessments may be based on a variety of factors, including:

Because so many resources can potentially be used, no limit is placed on what resources can be sent in RiskAssessment.basis. However, some resources would be nonsensical for this use (e.g. MessageHeader).

AllergyIntolerance and RiskAssessment

AllergyIntolerance describes a specific type of risk - propensity to reaction to a substance while RiskAssessment describes general risks to a subject, not generally based on a reaction.

Background and Context

Risk Assessments can be determined manually by health-care providers based on their professional expertise, by using an algorithmic scoring system or through a combination. Risk assessments can also be computed by decision support systems. OperationDefinitions may be defined by servers to generate risk assessments based on particular combinations of source resources or other inputs.
