Healthcare Databases Advanced Search (HDAS) will close down on 31 March 2022.

This means that you will not be able to access or use HDAS.

  • Any alerts you have saved will stop running and sending results to you.
  • All the search strategies and search results you have saved will be deleted.
  • You will only be able to access the databases from the providers' websites.

The information on this page will help you prepare for the closure.

What you need to do now

Export your data

You can export saved searches and results from HDAS. This means you can keep a copy of the searches you've done. The exported searches can then be repurposed and used on other search platforms.

If you have lots of saved searches, and you want to keep them all, make sure you allow enough time to export the data before 31 March 2022.

Unfortunately, we cannot help you to translate any exported searches into the logic used by other search platforms.

Request support

If your organisation has an NHS library service, contact your local library about moving from HDAS to provider interfaces.

Alternatively, email and our enquiry team will respond as soon as possible.

Other services you can use in future

Once HDAS has closed, you can access bibliographic databases from the providers' websites. For example:

  • Medline
  • Embase

Health Education England provides links to these databases and materials to help you search effectively.

You will need to sign in to the databases with your NHS OpenAthens account.

NHS Knowledge and Library Hub

Health Education England are launching a new resource discovery system. The NHS Knowledge and Library Hub will give you access to all the resources available to you.

  • Basic search will offer a keyword search of all the resources.
  • Journals A-Z search will show you which journals you can access.
  • For more advanced searching, access the databases via the providers' websites.

You will need to sign in with your NHS OpenAthens account to access the resources.
