A Secure Data Environment (SDE) is a new method of storing and accessing health and care data, and is also sometimes known as a Trusted Research Environment. These are spaces where approved users can access health and care data that is not identifiable for use in research that can save and improve lives.
Getting access is subject to strict approval processes and only approved users with a legitimate need can access the data. Those who could access the data includes NHS providers or local authority planners, researchers (both public and private sector), and charities.
