Detailed Descriptions for the elements in the NutritionIntake resource.

NutritionIntake
Element IdNutritionIntake
Definition

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.

NutritionIntake.identifier
Element IdNutritionIntake.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. 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.

Summarytrue
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 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.

NutritionIntake.statusReason
Element IdNutritionIntake.statusReason
Definition

Captures the reason for the current state of the NutritionIntake.

Comments

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.
