Health data holds enormous potential to advance medical research and improve patient care. Realising this potential requires more than making data available: sensitive information must be handled securely throughout the research process.

Within the Swiss Personalized Health Network (SPHN), secure technical infrastructures help enable privacy-preserving access to health data across institutions. They provide controlled environments in which researchers can analyse sensitive data without compromising confidentiality or transferring data unnecessarily. Clear access controls, technical safeguards and defined governance processes help protect patients while enabling scientific progress.

As health data research becomes increasingly collaborative and data-intensive, these infrastructures are essential for sustainable, trustworthy research. By supporting secure data use across institutional boundaries, SPHN contributes to a health data ecosystem that benefits research, patients and society.
