EHDS Logical Information Models
0.4.0 - draft

EHDS Logical Information Models, published by Xt-EHR. This guide is not an authorized publication; it is the continuous build for version 0.4.0 built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/Xt-EHR/xt-ehr-common/ and changes regularly. See the Directory of published versions

## Logical Model: Dosage model

Official URL: http://www.xt-ehr.eu/fhir/models/StructureDefinition/EHDSDosage | Version: 0.4.0
Draft as of 2026-02-23 | Computable Name: EHDSDosage

The model covers usage instructions for administering a medicinal product, focusing on the most frequently used data elements. More complex dosage schemes may require additional elements, which should be communicated as part of the rendered dosage instructions element.

Usages:

- Derived from this Logical Model: Administered dosage model and Dosage obligations
- Use this Logical Model: Medication dispense model, Medication prescription model and Medication use model

You can also check for usages in the FHIR IG Statistics

#### Dosage examples

##### Simple dosage examples

The following examples represent relatively simple dosage patterns, which are common across prescribing domain. All these patterns use only one dosage regimen. The renderedDosageInstruction is autogenerated from the structured information, and the exact algorithm may be language and implementation specific.
