Integration of Trusted Third Party Software into an EDC System for Data Protection - Compliant Identity Management, Consent Management and Pseudonymization in Medical Research Studies.

Introduction: Medical research studies which involve electronic data capture of sensitive data about human subjects need to manage medical and identifying participant data in a secure manner. To protect the identity of data subjects, an independent trusted third party should be responsible for pseudonymization and management of the identifying data.

Methods: We have developed a web-based integrated solution that combines REDCap as an electronic data capture system with the trusted third party software tools of the University Medicine Greifswald, which provides study personnel with a single user interface for both clinical data entry and management of identities, pseudonyms and informed consents.

Results: Integration of the two platforms enables a seamless workflow of registering new participants, entering identifying and consent information, and generating pseudonyms in the trusted third party system, with subsequent capturing of medical data in the electronic data capture system, while maintaining strict separation of medical and identifying data in the two independently managed systems.

Conclusion: Our solution enables a time-efficient data entry workflow, provides a high level of data protection by minimizing visibility of identifying information and pseudonym lists, and avoids errors introduced by manual transfer of pseudonyms between separate systems.
