description: A record of intake by a patient. A NutritionIntake may indicate that the patient may be consuming the food (i.e., solid and/or liquid), breastmilk, infant formula, supplements, enteral formula now or has consumed it in the past. The source of this information can be the patient, significant other (such as a family member or spouse), or a clinician. A common scenario where this information is captured is during the history taking process during a patient visit or stay or through an app that tracks food (i.e., solid and/or liquid), breastmilk, infant formula, supplements, enteral formula consumed. The consumption information may come from sources such as the patient's memory, from a nutrition label, or from a clinician documenting observed intake. package_name: hl7.fhir.r6.core derivation: specialization name: NutritionIntake type: NutritionIntake elements: instantiatesCanonical: {isModifier: false, short: Instantiates FHIR protocol or definition, type: canonical, mustSupport: false, array: true, isSummary: false, index: 1} instantiatesUri: {isModifier: false, short: Instantiates external protocol or definition, type: uri, mustSupport: false, array: true, isSummary: false, index: 2} derivedFrom: isModifier: false short: Additional supporting information refers: ['http://hl7.org/fhir/StructureDefinition/Resource'] type: Reference mustSupport: false array: true isSummary: false index: 39 encounter: isModifier: false short: Encounter associated with NutritionIntake refers: ['http://hl7.org/fhir/StructureDefinition/Encounter'] type: Reference mustSupport: false isSummary: true index: 9 reported: isModifier: false short: Indicates if this is a reported rather than a primary record.
