# Real-Life Examples

Here below are examples of customers that we helped building profiles.

## Nictiz
Nictiz is the centre of expertise for standardization and eHealth in The Netherlands. HL7 Netherlands core and MedMij profiles are published on [Simplifier](https://simplifier.net/NictizSTU3 "Nictiz project"). MedMij is a national project that aims to give Dutch citizens integrated access to all their health data in one personal health environment. FHIR is used as a standard to exchange health information between the involved parties. The profiles are based on standardized clinical building blocks called Health and Care Information Models (HCIM).

Below is an example of the Dutch profile on Medication, which is defined as the HCIM called ZIB Product.

In the Netherlands, the Z-Index maintains a classification system called the G-Standaard for medication. Different CodeSystems can be used to describe medication products and ingredients:
* GRP - Generic product codes to describe material, strength and way of prescription.
* HPK - Trade product codes to describe all information of a product and its supplier. Physicians use these codes to prescribe specific medication from a specific brand, for example when a patient has an allergy or intolerance for a particular material present in the same product from other suppliers.
* PRL - Prescription codes to describe material in a broader sentence, giving a broader choice between brands. For example, a pharmacist may choose to issue a cheaper variant of the same product.

Besides the registration of G-Standaard codes, ATC codes are registered as well. The Anatomical Chemical Therapeutical (ACT) classification is a hierarchical classification of medicines on organ (system) and therapeutical and chemical properties.

Nictiz has defined different ValueSets to capture the codes from these CodeSystems. In the Dutch Medication profile called ZIB-Product, the ``medication.code.coding`` and ``ingredient.itemCodeableConcept.coding`` elements are sliced. Each slice contains a required binding to one of these ValueSets. In this way, all codes are allowed, but the receiving party can distinguish between the different CodeSystems that are used.

## HelseVest 
HelseVest is a Norwegian health authority, responsible for the western region of Norway. One of their projects is the Helsevest Prescription project, which aims to provide integrations for medication prescription. Below is an example of one of the ValueSets that is used in this project.

The ValueSet includes all codes from the core units-of-time ValueSet, but excludes the code `wk` for week. Here below is the corresponding XML code.
