HL7 Fast Healthcare Interoperability Resource (FHIR)

FHIR (pronounced "fire") is a standard used to make healthcare data easier to share and exchange between different systems, like hospitals, clinics, and insurance companies. FHIR consists of resources which are predefined data structures for specific pieces of healthcare data. The following are the available nutrition-related resources:

• NutritionOrder: this resource describes a request for oral diets, oral nutrition supplements, enteral nutrition, and infant formula in the inpatient setting as well as other settings (eg, outpatient, home health). This resource captures the type of oral diet, any nutrient restrictions, and any texture modifications. For supplements, the resource captures the product, schedule, amount, and any special instructions. For enteral nutrition orders, the resource captures the product type and name, route of administration, scheduling, quantity, rate, and more. Modular additives are also accounted for.
• NutritionIntake: this resource describes intake by a patient. It allows for recording of food, liquid, breastmilk, infant formula, oral nutrition supplements, and enteral formula. The resource captures the item consumed (or not consumed), the amount, timing, and total nutrient and/or energy consumed.
• NutritionProduct: this resource describes a food (solid or liquid) or supplement product that can be consumed by a patient. The NutritionIntake resource references the NutritionProduct resource within its structure. This resource also captures the nutritional information, ingredients, and allergens for each product.
