How to use NICE indicators and how we develop them

Indicators can be used in a number of different settings to support high quality care. These include:

  • identifying where improvements are needed
  • setting priorities for quality improvement and support
  • creating local performance dashboards
  • benchmarking performance against national data
  • supporting local quality improvement schemes
  • showing progress that local health systems are making on outcomes.
