Background: Clinical information is often used for biomedical research. Data warehouses can help providing researchers with data and the opportunity to find eligible participants for clinical trials.

Objectives: To define an information platform for healthcare and biomedical research based on requirements by clinicians and researchers.

Methods: Interviews with clinicians, researchers, data privacy officers, IT and hospital administration combined with a questionnaire sent to 60 medical departments at our hospital were conducted.

Results: Resulting requirements were grouped and a platform architecture was designed based on the requirements.

Conclusion: Requirements lead to a single platform supporting both, patient care and biomedical research.
