A record of food or fluid that is being consumed by a patient. A NutritionIntake may indicate that the patient may be consuming the food or fluid now or has consumed the food or fluid 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 or fluid 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, animal or group who is/was consuming the food or fluid.

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 or fluid.

This attribute reflects the period over which the patient consumed the food fluid and is expected to be populated on the majority of NutritionIntake. If the food or fluid 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.

The person or organization that provided the information about the consumption of this food or fluid. Note: Use derivedFrom when a NutritionIntake is derived from other resources.

What food or fluid product or item was consumed.

Indicates what a category of item that was consumed: eg., food, fluid, enteral, etc.

Identifies the food or fluid product that was consumed. This is potentially a link to a resource representing the details of the food product (TBD) 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.

Scheduled frequency of consumption.

Quantity of the specified food.

Rate at which enteral feeding was administered.

Indicator when a patient is in a setting where it is helpful to know if food was not consumed, such as it was refused, held (as in tube feedings), or otherwise not provided. If a consumption is being recorded from an app, such as MyFitnessPal, this indicator will likely not be used.

Document the reason the food or fluid was not consumed, such as refused, held, etc.

Total nutrient amounts for the whole meal, product, serving, etc.

Individual item nutrients are not currently included in the resource and will likely end up as a reference in nutritionProduct to represent the individual items.

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

Total amount of nutrient consumed.

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 or fluid is /was consumed.

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