Medical Informatics
Fabian Prasser
Further advancing digital medicine requires innovative solutions for integrating healthcare and medical research data. From the perspective of medical informatics, there are important open questions. How can the required collection, integration and analysis of large and heterogeneous data sets be achieved in an efficient, effective and scalable manner? How can the trust of citizens and patients be maintained in the context of rapid change? These and related questions define the research profile of the group.
Research focus
We focus on four key areas: (1) technologies for interconnecting health data and for patient participation, (2) information integration and big data architectures in translational medicine, (3) cross-site data analysis and data sharing, (4) information security and data protection in digital medicine.
Our group conducts application-oriented research to create added value for health care and medical research, as well as basic research to develop novel methods with which the underlying challenges can be tackled more effectively.
Current Research Areas
- Pay-as-you-go integration systems for health data
- Scalable information infrastructures for medical research projects
- Clinical and translational data warehousing
- Data harmonization and semantic integration
- Methods and tools for applying privacy-enhancing technologies, such as anonymization and pseudonymization, in medicine
- Secure distributed computing in healthcare

Current projects
Within the Medical Informatics Initiative
Within the Medical Informatics Initiative
PrivateAIM: The goal of the PrivateAIM project is to develop a federated platform for privacy-preserving machine learning and data analytics in the MII. The general concept is that the analyses will come to the data, not the data to the analyses.
Further informationPCOR-MII: The goal of the PCOR-MII project is it to establish the digital recording of patient-reported outcomes (PROs) in clinics and to integrate them into the national core data set of the medical informatics initiative. The recording of PROs allows the subjective health status of patients to be systematically included in patient care and research.
Further informationHiGHmed: The partner sites of the HiGHmed consortium in the German Medical Informatics Initiative (MII) establish Medical Data Integration Centers (MeDICs), which integrate and harmonize data from healthcare and research systems. Important tasks include ensuring data quality and data protection to enable data sharing using the MII infrastructure. The added value of the solutions established will be demonstrated in various clinical and research use cases.
Further informationRISK PRINCIPE: The objective of this project is the development and implementation of a data-driven, risk-stratified infection control process using an automated monitoring system to effectively and efficiently minimize hospital bacteremias.
GeMTeX: The project's goal is to create a large annotated corpus of German medical texts from patient care, making them accessible in anonymized form for research.
Somnolink is an interdisciplinary project dedicated to the treatment of obstructive sleep apnoea (OSA) - a widespread disease that affects an estimated 26 million people in Germany. Despite its prevalence, OSA is often underdiagnosed but can have serious health effects if left untreated. As part of Somnolink, the existing infrastructure of the Medical Informatics Initiative (MII) is being expanded in order to integrate sleep data across different sectors and make it available for research. The aim is to improve diagnosis, treatment and therapy adherence for sleep-related illnesses, in particular obstructive sleep apnoea.
Further informationOpen Medical Inference: The project's aim is to simplify the use of AI in medicine by establishing a network of providers offering their AI models as "turnkey" services.

Prior Projects
Overview
Within the Medical Informatics Initiative:
CORD_MI: The Medical Informatics Initiative’s (MII) “Collaboration on Rare Diseases” (CORD_MI) aims to improve healthcare and research in the area of rare diseases. To achieve these goals, the technical as well as organizational solutions of the four consortia of the MII (DIFUTURE, HiGHmed, MIRACUM, SMITH) are utilized to share data on a nationwide scale. Further information
Within the Network of University Medicine:
The project "National Research Data Platform" (CODEX) of the Research Network of University Medicine on COVID-19 (NUM) aims to establish a secure and interoperable national data platform for research on SARS-CoV-2 and COVID-19. This will foster research on the current and future pandemics, as scientists from a wide range of disciplines will be able to quickly access a large number of standardized datasets. Further information
In CODEX+ the collaborative research infrastructure CODEX of the Network University Medicine (NUM) will be rolled out more broadly and developed further, with a focus on new data sources, common data models, data anonymisation and convergence with the structures of the Medical Informatics Initiative and further NUM projects. Further information
The NUM-RDP project operates a central platform for the aggregation and use of routine healthcare data in the University Medicine Network. It forms the technical basis for existing and future research projects that want to use the platform or and/or extend it with new software components. It receives, stores and provides data in an interoperable, open format. The Medical Informatics Group supports the project in the area of technical data protection and information security. Further information
Further Projects:The European Health Data & Evidence Network (EHDEN) aims to answer research questions based on large data sets distributed across Europe while preserving the anonymity of patients. With support from EHDEN, the Charité is building an infrastructure based on the Observational Medical Outcomes Partnership (OMOP) Common Data Model (CDM) and the associated tools of the Observational Health Data Sciences and Informatics (OHDSI) program to make health data accessible for research in a structured form. Further information
The European Joint Programme on Rare Diseases (EJP RD) brings together over 130 institutions from 35 countries to create a comprehensive, sustainable ecosystem for research, care and medical innovation in the area of rare diseases. In the project, the BIH Medical Informatics Group works on tools and methods supporting sustainable data sharing with a specific focus on privacy aspects. Further information
As part of the KI-FDZ project, the BIH Medical Informatics group is involved in the development and testing of anonymization and synthetization methods for routine data, as well as the experimental evaluation of the achieved level of protection. The aim is to build privacy-compliant anonymization pipelines for pilot datasets, systematically assess residual risks, and derive suitable methods for data provision at the German Research Data Centre for Health (Forschungsdatenzentrum Gesundheit).
