Medical Data Integration Center

As part of the ”HiGHmed” funding project, 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.


Aims of the MeDIC and HiGHmed

Primary aim of the MeDIC is the integration of different data sources (medical reports, x-rays, laboratory results, genomic data) within Hannover Medical School to improve patient care and research. Various institutes and departments of the MHH are cooperating to reach this goal.

The strategic aim of HiGHmed is to establish an infrastructure for the cross-institutional exchange of medical data in the coming years to improve patient care and research opportunities in cooperation with the partners of 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).

To foster patient participation from the beginning, another aim 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.

Of course, data protection, data security as well as data privacy (informational self-determination) of the patients are of highest importance.


Use Cases and Advantages

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

  • 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.
  • 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.
  • 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.
