This project contains HL7 FHIR compliant profiles for the information standard Medication Process 9.

A medication agreement is an agreement between the prescriber and the patient regarding the use of medication by that patient. An agreement to stop or change medication use is also a medication agreement.

The prescribed substance is usually medication. However medical aids and bandages can also be prescribed and supplied via the pharmacy. Food and blood products do not strictly belong in the medication category but can be prescribed and supplied by a pharmacy as well. A type of medication can be indicated with **a single code**. That code can be chosen from several possible coding systems (concretely GPK PRK HPK or article numbers). Correct use of these codes in the software systems will sufficiently record the composition of the product used making a complete product specification unnecessary. In addition to a primary code **alternative codes** from other coding systems can also be entered (so that the GPK can be sent along in the event that the patient was registered based on PRK for example). Entering multiple ingredients will enable you to display a compound product. If one of the composite parts is liquid the dosage will be given in milliliters; otherwise it will be given in ‘units’. In that case the **composition of the medication** can be specified implicitly (with the use of a medication code) or explicitly for example by listing the (active) ingredient(s) of the medication. **Magistral prescriptions** can be entered as well. This can be done by means of the option listed above to enter coded ingredients and or by entering the composition and preparation method as free text. This is a partial information model.

Instructions for the use or administration of the medication e.g. dose and route of administration. In the medication building block MedicationUse this is the pattern of use established by the patient or which the patient followed.

A medication dispense is the provision of a supply of a medicine to the patient their representative or administrator.

Medication use is a statement about the patient's historical current or intended use of a medicine. The statement can be recorded by the patient themselves but also by a healthcare professional or a representative of the patient.

A dispense request is a request from a prescriber to the supplier to dispense medication to the patient in line with the corresponding medication agreements.

An administration agreement contains the instructions for the use or administration of medication given by the supplier to the patient their representative or administrator. With this the medication agreement is specified in concrete terms.

Pre-adopt of the `.renderedDosageInstructions` concept from the FHIR R5 medication resources. It provides a full representation of the dose of the medication included in all dosage instructions. To be used when multiple dosage instructions are included to represent complex dosing such as increasing or tapering doses.

An extension to provide the date and time a certain medication agreement variable-dosing regimen administration agreement or medication administration was recorded. For the medication administration this extension can be seen as a pre-adopt of the `MedicationAdministration.recorded` element that has been added in FHIR R5.
