The NICE Glossary provides brief definitions and explanations of terms used on our site. The terms describe how we work and how our guidance is produced.

Our glossary excludes specific clinical and medical terms. If you cannot find the term you are looking for, please email us so that we can consider adding it to the glossary.

Some definitions and examples are based on those in the 'HTAi consumer and patient glossary', with thanks to Health Technology Assessment International.

  • Update for primary care

    A monthly publication for primary care staff, which summarises the latest guidance relevant to primary care. Also contains other NICE news items.
  • Utility

    In health economics, a 'utility' is the measure of the preference or value that an individual or society places upon a particular health state. It is generally a number between zero (representing death) and 1 (perfect health). The most widely used measure of benefit in cost-utility analysis is the quality-adjusted life year, but other measures include disability-adjusted life years (DALYs) and healthy year equivalents (HYEs).
