Methododology Platforms

As part of the medical informatics initiative, methodology platforms are being developed to support the availability and analysis of data across locations. The MHH participates in two methodology platforms: GeMTeX and SU-TermServ.



The overall aim of GeMTeX "German Medical Text Corpus" is to provide a large annotated corpus of anonymised German-language medical texts for research purposes. The texts should reflec the breadth of texts occurring in routine patient care. Texts can be doctor's letters or findings from radiology, pathology or other disciplines. It is planned to use only texts from patients who have agreed to their use via the so-called Broad Consent. The broad consent is the patient’s agreement that their medical data and images may be used for scientific purposes, without a specific purpose being already known at the time of the consent. This opens up the possibility for scientific research to be able to use existing data from routine care more flexibly than in the past, without having to obtain the patient's consent for each individual research question. However, this consent only applies to routine data that arise from the pure observation of the patient. If a patient takes part in a study, a separate consent must be signed.

The MHH does not participate in the project GeMTeX on the level of providing medical texts, but on a purely methodological level. In this context, the MHH provides concepts and methods for a computerised acquisition and presentation of molecular pathology reports.



Another method platform in which the MHH is involved is the SU-TermServ project (Service Unit "Terminological Services").
In order to meet the requirements of interoperability at all medical sites in Germany, a central terminology server and supplementary IT services are necessary. With the help of this terminology server, all actors are enabled to use the same coding systems and to retrieve relevant terminological resources at any time. In order to support semantic interoperability at all operational levels, i.e. essentially

  • for modelling FHIR profiles and openEHR archetypes,
  • for validation of instantiated profiles or templates during data exchange, and
  • for queries or analyses of (coded) data,

a professional provision of agreed terminological resources and services is required. The purpose of the planned service unit is to ensure stable operation and to provide trained staff with the necessary expertise.
