Evidence services



NICE evidence services provide access to trustworthy, high-quality evidence and best practice information.

They support professionals so they can make timely, evidence-based decisions. They are developed primarily with professionals and practitioners in mind, but patients and the wider public can also search and use much of the content.

Five of our evidence services are available through the NICE website:

  • Evidence search – providing free open access to trustworthy evidence in health, social care and public health.
  • Journals and databases –including Healthcare Database Advanced Search (HDAS), which is aimed at the expert user and provides access to an extensive set of journals and bibliographic databases.
  • Clinical knowledge summaries (CKS) - providing primary care practitioners with access to evidence-based guidance on more than 330 key topics, including cancers, neurological diseases and cardiovascular conditions.
  • British National Formulary (BNF) – providing advice and information on prescribing and pharmacology for adults and children.
  • Evidence awareness services – providing daily and weekly email alerts, to help busy professionals keep up to date with important new evidence related to medicines.

One of our evidence services is available through a partner website:

  • UK pharmaScan - a horizon-scanning database which includes information about new medicines in development by over 175 registered pharmaceutical companies. NHS England uses this database as its primary source of information on new medicines.

Highlights of 2016-17:

We redeveloped the healthcare database advanced search (HDAS) to improve its performance and stability as well as the user experience. The new live version of HDAS launched in October 2016.


In December 2016, we introduced new ‘evidence type’ filters to the NICE website. These filters split our resources into categories, which makes the search quicker for users. The filters were developed and agreed with Public Health England to help with the sharing of evidence.
