9.13 Resource NutritionRequest - Content

Orders and Observations Work Group Maturity Level : 1 Compartments : Encounter , Patient , Practitioner

A request to supply a diet, formula feeding (enteral) or oral nutritional supplement to a patient/resident.

9.13.1 Scope and Usage

This resource is a request resource from a FHIR workflow perspective - see Workflow . It is the intent of the Orders and Observation Workgroup to align this resource with the workflow pattern for request resources .

The NutritionRequest resource describes a request for oral diets (including general diets such as General Healthy diet, or therapeutic diets such as Consistent Carbohydrate, 2 gram Sodium, or Fluid Restricted), oral nutrition supplements (such as nutritionally complete pre-packed drinks), enteral nutrition (tube feedings) and infant formula which govern the distribution of food and nutritional products used to feed patients within an in-patient setting. It does not cover orders for parenteral (IV) nutrition which are typically filled by pharmacy. These nutrition orders are combined with information on a patient's food allergies and intolerances, and ethnic or cultural food preferences (e.g. Kosher or Vegetarian) to inform healthcare personnel about the type, texture, and/or quantity of foods that the patient should receive or consume.

Enteral orders are distinguished from supplements because they have some unique attributes and typically include administration information whereas oral nutritional supplements may simply be supplied (e.g. home health or outpatient settings). In a simple case, the requestor may designate type of product, product name and the route of administration along with free text instructions without a having to complete the additional structured details.

This resource is intended to be used by providers from a variety of specialties such as physicians, dietitian/nutritionists, or speech therapists. One provider may simply order a base element oral diet such as General Healthful diet. Another provider, based on scope of practice, may use other elements to communicate additional therapeutic needs or patient preferences. The optionality included gives an ordering provider the capability to write a simple order for an oral diet, nutritional supplement or formula with minimal requirements beyond that of specifying the diet, supplement or formula product, but also supports the ability to provide more detailed information that may be further augmented by a dietitian or nutrition specialist. For example, a physician may order a 2 g sodium diet. A speech therapist, based on the results of a swallowing evaluation, then orders a mechanically altered texture with nectar thick liquids.

9.13.2 Boundaries and Relationships

The NutritionRequest resource is used for requesting oral diets, oral nutrition supplements and enteral feedings in an in-patient setting. The MedicationRequest resource should be used for requesting parenteral (IV) nutrition and prescribing dietary supplements such as vitamin or mineral supplements.

The Nutrition Order is a record of the request for the supply of a diet, oral supplement or enteral formulas for a patient. However, to initiate the request requires the use of the Task resource and its associated workflow with the Nutrition Order referenced from the Order.details, or by using the Nutrition Task resource in the context of a messaging or service workflow where the request is explicit or implicit.

9.13.3.2 Constraints

  • nor-1 : Nutrition Order SHALL contain either Oral Diet , Supplement, or Enteral Formula class ( expression : oralDiet.exists() or supplement.exists() or enteralFormula.exists() )

9.13.4 Notes:

9.13.4.1 Enteral continuous vs. intermittent tube feedings

Tube feedings can be administered via continuous drip using a pump or via intermittent feedings, using gravity drip or a pump. The examples Nutrition Order Enteral Bolus Feeding Example and Nutrition Order Enteral Continuous Feeding Example show how this resource can be used to order both kinds of enteral feeding using the structured data elements. The continuous feeding typically specifies rate of administration and a maximum volume of delivery using the enteralFormula.rate and enteralFormula.maxVolumeToDeliver elements. On the other hand, the intermittent feeding typically specifies the amount and frequency of administration using the enteralFormula.quantity and enteralFormula.schedule elements. In both cases, to vary the rate or quantity over time the enteralFormula.administration element can be repeated.

9.13.4.2 Note about the examples

The examples associated with this resource demonstrate the core elements and do not necessarily reflect real world implementations that may be constrained by future profiles for a given implementation or setting. For example, a renal diet is often comprised of pre-coordinated components including common nutrient modifications such as protein, potassium and phosphorus to assist with the speed of entry of complex diet orders.
