OSSE (Open Source-Registersystem für Seltene Erkrankungen in der EU / Open Source Registry System for Rare Diseases in the EU) provides patient organizations, physicians and scientists with open-source software for the creation of patient registries. As a result, the national registry landscape is improved to comply with European principles regarding e.g. minimum data set and data quality, as summarized in the EUCERD recommendation on rare disease registries. Also, the necessary interoperability is achieved to facilitate federation of those registries on a national and international level.
The registry toolbox
OSSE primarily provides a registry toolbox that allows for the definition of forms for longitudinal and medical core data and of the corresponding data schema by means of a registry editor. Common data elements, which can be chosen to build the forms, are defined within a metadata repository (MDR) following ISO/IEC 11179. This approach provides semantic interoperability and data quality. All harmonized data sets for rare diseases will be available through the MDR. Further items can be added at any time while building disease-specific registries and will be available for all OSSE-compliant registries. The OSSE registry provides plausibility checks regarding ranges defined in the MDR and field-specific dependencies, data versioning, workflow support, interfaces for configurable data import and export, and role-based access control.
To meet data protection requirements, OSSE supports pseudonymization of patient data: the part of the data allowing for the identification of patients is replaced by a pseudonym and stored separately in the patient list that should be controlled by a trusted third party. For pseudonymization we use the opensource software “Mainzelliste” ["http://www.mainzelliste.de"].
Interoperability between different OSSE registries is achieved by a distributed search infrastructure taking into account data ownership and privacy aspects. The central search broker allows specified search queries in all OSSE-compliant registries based on the existing MDR items. Results are presented to the person in charge of the data management for each registry; the exchange or dissemination of data remains in full control of the data owner.
There are two related projects currently underway at the University Medical Center in Mainz: se-atlas, an interactive map of relevant experts on rare diseases in Germany; and ZIPSE, a central information portal on rare diseases in Germany.
OSSE is funded by the German Federal Ministry of Health as part of the “National Action Plan for Rare Diseases”. For more information see http://osse-register.de.
