Log in to the Data Access Environment.
If you require access to HES data or DAE you will need to register with DARS first.
The Data Access Environment (DAE) provides secure access to the health and care data we hold and reduces the need for it to leave NHS Digital. It caters for standard DAE users with access to standard data sets, and is the platform that supports our Trusted Research Environment (TRE) service for England, providing access to Covid-related data sets for research.
DAE contains a range of built-in tools to interrogate, analyse and visualise data for a more complete picture of health and care for research and planning.
Advanced processing matches and de-identifies person-level records for improved data linkage, providing a secure and more complete set of data to support research.
All data access is strictly managed by our Data Access Request Service (DARS). Over time, DAE will integrate with DARS to provide an improved customer experience and make requesting and receiving quicker and easier for customers.
If you need to start a new application, please contact the DARS team to discuss your requirements. Not all enquiries progress to the application stage as it may be that your request can be catered for using existing publications.
A Data Sharing Agreement (DSA) is required before users can access data using DAE. If you have an existing DSA in place, it will need to include permission to access data using DAE. Once approved, users are issued with a DAE username.
To discuss any aspect of DARS or an existing application call the DARS team on 0300 303 5678 or email email@example.com.
DAE hosts some of the world’s leading analytics tools. The suite is designed to support all analysis, reporting and publication requirements, whilst providing powerful options to deliver world class data visualisation and analysis. The tools you have access to will depend on your project needs and arrangements.
Databricks is a collaborative analytics platform that supports SQL, Python and R languages for the analysis of big data in the cloud.
RStudio is a development environment for the R statistical language. It is made by statisticians for statisticians to make your work more productive.
Other tools can be hosted on the platform, depending on individual project needs.
If you have any questions or require further support, please get in touch.
We are developing our data processing services to transform how we collect, process and use data to improve health and care.
NHS Digital’s Trusted Research Environment (TRE) service for England provides approved researchers with access to essential linked, de-identified health data to quickly answer COVID-19 related research questions.
The Data Access Request Service (DARS) can offer clinicians, researchers and commissioners the data required to help improve NHS services. We handle applications, process data and provide access to specific sets of data when requests are approved.
A description of the data products we use to provide data extracts and other services.
Who hospital episode statistics (HES) are for, how they are used and how to apply for access. This includes the local authority HES Data Extract Service.
Maintenance is planned on Data Access Environment (DAE) at the following dates and times. The system may be unavailable during these times.
Master Person Service (MPS) is an enhanced patient-matching algorithm that increases the number of linkable records where incomplete records have been submitted.
‘De-identification’ protects people’s data and enables safe linkage across data sources. This enriches analysis by providing a more complete picture of health and care data.
This video explains how to use HES data. It provides users with valuable context, leading to a better understanding of the data and how it's produced.
