9.11 Resource RiskAssessment - Content

Clinical Decision Support icon Work GroupMaturity Level: 2 Trial UseSecurity Category: Patient Compartments: Device, Patient, Practitioner

An assessment of the likely outcome(s) for a patient or other subject as well as the likelihood of each outcome.

9.11.1 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:

  • A prognosis statement for a particular condition
  • Risk of health outcome (heart attack, particular type of cancer) on the basis of lifestyle factors and/or family history
  • List of potential health risks based on a patient's genetic analysis
  • A prediction of outbreak infection rates within a geography based on immunization rates

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.

9.11.2 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.

9.11.3 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.
