NHS Digital is committed to only releasing patient and service user data to those who have a genuine need for it and can demonstrate this to an independent oversight panel.

Help us to improve these pages

These pages are in public beta. You can complete this short questionnaire to provide feedback. 

These pages provide a link to the description of data sets readily available to request through our Data Access Request service (DARS). These data may be provided in the Secure Data Environment or as an extract. For clinical trials you may also want to use the DigiTrials Service which can also provide access to this data. 

Data not included

Please be aware that due to the differences in the cohorts used to create publications versus those in the data sent out via NHS England data sharing agreements, it may not be possible to reproduce results from official statistical publications using data disseminated under an NHS England data sharing agreement.
