Medical Data Integration Center

As part of the funding project „HiGHmed“ (Heidelberg-Göttingen-Hannover Medical Informatics), a medical data integration center (MeDIC) is established at Hannover Medical School (MHH) in cooperation with several other university hospitals, the German Cancer Research Center and other partners in healthcare, science and industry.


Primary goal is the integration of multilocal, heterogeneous data within MHH to improve patient care and research. Various institutes and clinics of the MHH cooperate in the MeDIC, i.e. the Peter L. Reichertz Institute for Medical Informatics of TU Braunschweig and Hannover Medical School (PLRI), the Center for Information Management (ZIMt), the Department of Cardiology and Angiology, the Department of Gastroenterology, Hepatology and Endocrinology, the Institute for Diagnostic and Diagnostic Interventional Radiology, the Institute of Medical Microbiology and Hospital Epidemiology, the Institute of Human Genetics, the Institute for Radiation Therapy and Special Oncology and others.


The strategic goal of the MeDIC is to establish an infrastructure based on internationally accepted, open standards for the cross-institutional exchange of medical data in the coming years to improve patient care and research opportunities in cooperation with the partners in the HiGHmed project. To achieve this goal, data must be interoperable in the participating institutions. The conditions and necessary measures for interoperability and interchangeability of the data are therefore coordinated across the institutions (common information management). Of course, data protection, data security as well as data privacy (informational self-determination) of the patients are of highest importance.


The cross-institutional exchange of medical data is expected to improve patient care within three exemplary use cases:

  • Use Case Oncology: In patients with cancer, the expertise of specialists will be consulted in cross-institutional molecular tumor boards. Hereby, extensive data about treatment and progress of the disease are integrated, prepared and presented to the doctors participating in the tumor boards.
  • Use Case Cardiology: Patients with heart failure will be enabled to link their own health-related data (such as physical activity data) with their patient record to document the further recovery process beyond their inpatient stay. Thus, an information system will be established, which provides physicians with objective measures and enables targeted recommendations.
  • Use Case Infection Control: This use case aims for the early detection and prevention of infection clusters of various pathogens (e.g., MRSA) by analyzing combined patient movement (admission, transfer, and discharge) and microbiology data within the hospital.

Research also benefits directly from the possibilities of exchanging data across institutions. On the one hand, information about similar cases can contribute to successful treatment. On the other hand, it will be possible to obtain a reliable number of cases for very rare diseases for statistical analyses and to gain new insights into the causes and course of diseases.


To foster patient participation from the beginning, another goal is to establish an innovative patient portal so that patients can access their own data on the course of treatment as well as further information about their disease.
