Positive weight for an explicitly true Boolean answer to a risk questionnaire item. False contributes zero. Missing or unknown is not false and must not be scored by omission. This extension records a weight, not a validated outcome probability or an executable calculation.
Context of Use
This extension may be used on the following element(s)
Questionnaire.item
In addition, the extension can only be used when these FHIRPath expressions are true:
type = 'boolean'
extension.where(url = 'https://fhir.heartlandprotocol.org/StructureDefinition/heartland-risk-true-points').count() = 1
