A record of intake by a patient. A NutritionIntake may indicate that the patient may be consuming the food or fluid now or has consumed 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 or fluids 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.

Identifiers associated with this Nutrition Intake that are defined by business processes and/or used to refer to it when a direct URL reference to the resource itself is not appropriate. They are business identifiers assigned to this resource by the performer or other systems and remain constant as the resource is updated and propagates from server to server.

This is a business identifier, not a resource identifier.

Instantiates FHIR protocol or definition.

Instantiates external protocol or definition.

A plan, proposal or order that is fulfilled in whole or in part by this event.

Allows tracing of authorization for the event and tracking whether proposals/recommendations were acted upon.

A larger event of which this particular event is a component or step.

This should not be used when indicating which resource a NutritionIntake has been derived from. If that is the use case, then NutritionIntake.derivedFrom should be used.

A code representing the patient or other source's judgment about the state of the intake that this assertion is about. Generally, this will be active or completed.

NutritionIntake is a statement at a point in time. The status is only representative at the point when it was asserted. The value set for NutritionIntake.status contains codes that assert the status of the consumption of the food (i.e. solid and/or liquid), breastmilk, infant formula, supplements, enteral formula by the patient (for example, stopped or on hold) as well as codes that assert the status of the Nutrition Intake itself (for example, entered in error).

This element is labeled as a modifier because the status contains codes that mark the resource as not currently valid.

Captures the reason for the current state of the NutritionIntake.

This is generally only used for "exception" statuses such as "not-taken", "on-hold", "cancelled" or "entered-in-error". The reason for performing the event at all is captured in reasonCode, not here.

Overall type of nutrition intake.

The person or group who is/was consuming the food (i.e. solid and/or liquid).

The encounter that establishes the context for this NutritionIntake.

The interval of time during which it is being asserted that the patient is/was consuming the food (i.e. solid and/or liquid).

This attribute reflects the period over which the patient consumed the food (i.e. solid and/or liquid) and is expected to be populated on the majority of NutritionIntake. If the food (i.e. solid and/or liquid) is still being taken and is expected to continue indefinitely at the time the usage is recorded, the "end" date will be omitted. If the end date is known, then it is included as the "end date". The date/time attribute supports a variety of dates - year, year/month and exact date. If something more than this is required, this should be conveyed as text.

The date when the Nutrition Intake was asserted by the information source.

Indicates if this record was captured as a secondary 'reported' record rather than as an original primary source-of-truth. It may also indicate the source of the intake record.

The nutrition product intended for consumption and/or administration.

Indicates what a category of item that is intended to be consumed: e.g., food (i.e. solid and/or liquid), breastmilk, infant formula, supplements, enteral formula.

Identifies the food (i.e. solid and/or liquid) product that is to be consumed. This is potentially a link to a resource representing the details of the food product or a simple attribute carrying a code that identifies the food from a known list of foods.

If only a code is specified, then it needs to be a code for a specific product. If more information is required, then the use of a new nutritionProduct resource is recommended.

What nutrition item was consumed.

Scheduled frequency of consumption.

Quantity of the specified food (i.e. solid and/or liquid) .

Rate of enteral feeding administration.

Nutrients and/or energy contained in the intake.

Type of nutrient consumed. This could be a macronutrient (protein, fat, carbohydrate), or a vitamin and mineral.

Total amount of nutrient consumed.

Total energy consumed in kilocalories or kilojoules.

Indicator that the nutrition item was not consumed, such as it was refused, held (e.g., tube feedings), or otherwise not provided.

Document the reason the nutrition item was not consumed, such as refused, held, etc.

Who performed the intake and how they were involved.

Type of performer.

Who performed the intake.

Where the intake occurred.

Allows linking the NutritionIntake to the underlying NutritionOrder, or to other information, such as AllergyIntolerance, that supports or is used to derive the NutritionIntake.

Likely references would be to AllergyIntolerance, Observation or QuestionnaireAnswers.

A reason, Condition or observation for why the food (i.e. solid and/or liquid) is /was consumed.

Provides extra information about the Nutrition Intake that is not conveyed by the other attributes.
