1.9.0 - Standard for Trial Use

This page is part of the CH EMS (R4) (v1.9.0: STU) based on FHIR R4. . For a full list of available versions, see the Directory of published versions



This FHIR implementation guide defines a standardised information workflow applicable to Swiss emergency services (EMS). It is used as a basis for projects to digitalise the processes in the Swiss emergency services and to connect these organisations to other EMS, hospitals and the Swiss Electronic Patient Record (EPR).
The project is under the leadership of the “Interverband für Rettungswesen”.
This information workflow is established as standard at the association eCH under the number eCH-0207, Version 2, and at eHealth Suisse under the name CH-EMS (official data exchange format according to Swiss legislation).

Swiss specific context

The CH EMS implementation guide describes the FHIR representation of the defined Emergency Medical Service protocol. This implementation guide is dependent on CH Core and CH EPR Term, which describe the Swiss specific context, especially related to the Swiss electronic patient record (EPR).

Swiss context

The CH EMS profiles are based on the CH Core basic profiles. Thus, the examples of the EMS protocols (Einsatzprotokolle 1, 1b, 2, 2b) are valid in the Swiss context. In order to verify the correctness, the documents can be validated against the CH EMS Document Profile. (The requirements of the CH Core Document Profile are thus also fulfilled and checked).

Validation: see README CH EMS

Swiss EPR context

If the documents are used in the EPR context, the requirements of the CH Core Document Profile EPR must also be fulfilled. For the use case of the emergency services, there are two main aspects that must be considered in the EPR context:

  • The social security number (AHVN13) of the patient must not be stored in the EPR
  • For a valid EPR document, the name of the patient must be known, which is not always guaranteed in emergency services

To support the compatibility check against the CH Core EPR profiles, a warning is generated in case of deviations during validation:
‘ch-ems-epr: Warning that the resource is not conform to the CH Core EPR restrictions’

Validation: see README CH Core
