What is an SDE?

Secure Data Environments, or SDEs, are online platforms for approved researchers to safely analyse sensitive data.

The NHS Research Secure Data Environments will provide access to analyse routinely collected health and social care data.

SDEs are also sometimes called Trusted Research Environments (TREs) or Secure Research Environments (SREs).

In 2022, a government review by Professor Ben Goldacre recommended using SDEs for healthcare research to make sure our personal data is as secure as possible. This was adopted as a government policy in Data Saves Lives, with the SDE programme funded from 2023.

SDEs securely host data from many different organisations across a region. This allows researchers to look at data from many different places. By linking this data, they can discover completely new insights about diseases and their treatments.

This SDE approach means data isn’t sent or used for any purpose other than the approved research. This approach has already been tested for several years. SDEs take it to a larger, regional scale.

SDEs could revolutionise how data is used in research. They could lead to improvements in treatments and health for everyone.

An NHS England programme

NHS England is funding regions to set up local SDEs. There will be 11 regional SDEs as well as a national one led by NHS England.

What are the benefits?

Better security

SDEs hold data securely in one place and analysis happens within the SDE.

Researchers only access the data they need for their project. Once their research is complete, their access to this data is removed.

More efficient research

SDEs will speed up the research process, making it more efficient.

Researchers will request access from one data controller, rather than several different organisations. This will also reduce the time NHS and other organisations spend dealing with access requests.

Opening up new research possibilities

Researchers will have a better understanding of what data is gathered across our region. Having access to such a rich data set will enable boundary pushing research.
