<a id="NutritionIntake"></a>

## NutritionIntake
Record of intake by a patient

**Definition:** 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.

## NutritionIntake.identifier
External identifier

**Definition:** 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.

<a id="NutritionIntake.status"></a>

## NutritionIntake.status
preparation | in-progress | not-done | on-hold | stopped | completed | entered-in-error | unknown

**Definition:** 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.

**Comments:** 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.

**Cardinality:** 1..1

**Type:** [code](/code)

**Binding:** required:[event-status](/valueset-event-status)

**Summary:** true

**Is Modifier:** true (Reason: This element is labelled as a modifier because it is a status element that contains status entered-in-error which means that the resource should not be treated as valid)

<a id="NutritionIntake.statusReason"></a>

## NutritionIntake.statusReason
Reason for current status

**Definition:** Captures the reason for the current state of the NutritionIntake.

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

**Comments:** 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.
