The CH EMED implementation guide describes the FHIR representation of the documents for the exchange of medication information in the context of the EPR (electronic patient record) in Switzerland. This implementation guide is dependent on CH Core and CH Term, which describe the Swiss specific context, especially related to the Swiss EPR.
Initially this implementation guide was based on the CDA-CH-EMED eMedication ART-DECOR® specification which has been published by eHealth Suisse. CDA-CH-EMED defined the eMedication documents for the information exchange in the context of the EPR in Switzerland. The documents were based on the IHE Pharmacy Technical Framework modelled and specialized in the Building Block Repository CH-PHARM. Base for this modelling was the report from IPAG eMedikation, 7.6.2017 and the work of IPAG/eHealth Suisse.
Due to difficulties in modeling and mapping, the further development of the specifications, especially in the area of dosage, has been difficult. This and the fact that the format CDA-CH-EMED was only little in use, led then to the fact that the CDA format was abandoned and the exchange format on the basis of FHIR was developed further.
Scope
The following documents have been defined (and described in more detail on the respective subsections):
The use case (de, fr) illustrates the processes related to medication. In successive steps, situations are depicted in which the various eMedication documents are used. For each step, the structured FHIR examples are provided.
To explain the different focus areas in more detail, there is a guidance section with the following topics:

MustSupport
For all elements listed in the minimum data set in the IPAG report the corresponding FHIR elements 'mustSupport' flag have been set to true. 'MustSupport' flags are currently only defined for the Medication Card document.
Meaning of the Flag MustSupport for this Implementation Guide
The flag mustSupport follows the IHE use of R2 as defined in Appendix Z. It demands that the content creator must support these elements if they are known. If the sending application has data for the element, it is required to populate the element with a non-empty value. If the value is not known, the element may be omitted. A receiving application may ignore the information conveyed by the element. A receiving application shall not raise an error solely due to the presence or absence of the element.
Implication of MustSupport to the Original Representation
The original representation of the Medication Card document and the Medication Prescription document must be embedded as a PDF in PDF/A-1 or PDF/A-2 format. If elements of the minimum data set in the IPAG report are provided in the bundle, they are also required to be represented in the original representation (PDF). Guidance on the readable representation of EPR documents with an example of handling the referencing from narrative to data can be found here.
