Access and institutional requirements

Saved history and institutional features remain restricted and are not currently available for new access requests. You may register your interest using the access-request topic.

Evaluation study

Independent validation needs a participating institution. Scope, approvals and data handling are agreed before any work with patient data. A contact request does not enroll a hospital or authorize clinical use.

Data handling

Institutional data use and any business associate agreement are reviewed before setup. The privacy policy states what is stored and where.
