eRezept App

Introduction

Prescriptions for medicines that are only available in pharmacies can be issued as electronic prescriptions (e-prescriptions resp. E-Rezepte) for people with public health insurance from 1 July 2021. The official gematik E-Rezept App (electronic prescription app) is available to receive and redeem prescriptions digitally. Anyone can download the app for free:

and login with the health card of the public health insurance. In July 2021, the e-prescription will start with a test phase, initially in the focus region Berlin-Brandenburg. The nationwide rollout will follow three month later in the fourth quarter.

The e-prescriptions are stored in the telematics infrastructure, for which gematik is responsible.

Licensing

The E-Rezept App is licensed under the European Union Public Licence (EUPL); every use of the E-Rezept App Sourcecode must be in compliance with the EUPL.

Development

Getting started

run $ make setup to start developing locally. This will make sure all the dependencies are put in place and the Xcode-project will be generated and/or overwritten.

You'll need a running implementation of IDP and FD. A reference implementation for IDP and FD is available.

Documentation for setting up the entire system will be available at a later date.

Project setup

Dependencies are a mix of SPM (Swift Package Manager) and Carthage right now. The Xcode-project is generated using xcodegen. The more complex build configuration(s) is done with the help of Fastlane. See the ./fastlane directory for full setup.

The App uses Apple's Combine.framework for operation scheduling. The UI-Layer is built with The Composable Architecture ♥️ and SwiftUI ♥️. Minimum platform requirements are: MacOS 11 and iOS 14.0

Modularization

The app is composed of several modules:

• eRpApp is the iOS front-end (consumer facing) eRezept App.
• eRpKit bundles all non platform specific business logic.
• eRpLocalStorage and eRpRemoteStorage serve as the FHIR communication module to send and request all the eRezept resources and store them locally.
• Pharmacy handles communication with the Pharmacy API.
• FHIRClient powers eRpRemoteStorage and Pharmacy by providing a generic FHIR interface (see FHIR for more information about the FHIR standard).
• HTTPClient provides the interface for HTTP communication within the project.
• IDP is used for authentication against the eHealth network.
• VAU provides an encrypted communication channel with the eHealth network.
• TrustStore validates trust with a given trust anchor and handles ocsp responses.

You can find more documentation about each module here.

Generated Source

We use sourcery to generate some data structures. Run $ sourcery to update generated code. The compiler will tell you, if you need to update the generated code by running sourcery in most cases. As sourcery is used as a weak (generated code is checked in, CI is not executing sourcery) dependency, you have to install sourcery manually by running $ brew install sourcery.

Build iOS app for release

Run $ make build

Note: make sure you've ran $ make setup before and have code-signing setup for your local (or ci-build) build.

Functional Requirements

The underlying requirements can be found within the Gematik Fachportal. Search for "E-Rezept Frontend des Versicherten".

A mapping of these requirements can be found within the documentation. To generate the mapping from requirements to implementation run bundle exec fastlane list_requirements.
