Extension: doNotPerform

FHIR Infrastructure Work Group

Maturity Level: 1

Informative

Use Context: Any

URL for this extension:

http://hl7.org/fhir/StructureDefinition/request-doNotPerform

Status: draft. Extension maintained by: Health Level Seven, Inc. - FHIR WG

If true indicates that the request is asking for the specified action to not occur.

Comment:

The attributes provided with the request qualify what is not to be done. For example, if an effectiveTime is provided, the "do not" request only applies within the specified time. If a performerType is specified then the "do not" request only applies to performers of that type. Qualifiers include: code, subject, occurrence, perormerType and performer.

In some cases, the Request.code may pre-coordinate prohibition into the requested action. E.g. "NPO" (nothing by mouth), "DNR" (do not recussitate). If this happens, doNotPerform SHALL NOT be set to true. I.e. The resource shall not have double negation. (E.g. "Do not DNR").

Context of Use: Use on Element ID NutritionOrder
