Public consultation by NHS Digital on planned amendments to Compenium Indicators

Closed 22 Jun 2018

Opened 10 May 2018

Feedback updated 30 Aug 2018

We asked

We asked for feedback on proposed changes to:

  •  the way indicators are reported
  • archiving and signposting indicators we no longer update or hold the most relevant data for
  • the new approach to disclosure control to be adopted across all compendium indicators

You said

The responses received supported each of our proposals.  In respect of the second proposal, the need for the archive to be easy to access and fully searchable was highlighted. 

Several items of supplementary feedback not directly related to the proposals were also received, and specific responses have already been sent out to the individuals concerned.

We did

After careful consideration, we decided to abandon our first proposal in relation to amalgamating indicators.

Our second proposal was to signpost all indicators where more contemporary information is held elsewhere, and to move indicators to a new ‘archive’ series where this is not possible.  We intend to complete this work by the end of 2018.

Our final proposal was to adopt a ‘central suppression’ method, based on rounding, across all compendium indicators to speed up production and make suppression more reliable.  This will be implemented henceforth, starting with the compendium mortality indicators that are due to be released in batches from Autumn 2018 onwards. 

The central suppression method will be applied flexibly where necessary to ensure full compliance with births and deaths disclosure control guidelines published by data providers such as the Office for National Statistics (ONS).

There are a series of compendium indicators relating to hospital readmissions within 28 days where planned updates have been postponed pending methodological review, but which are known to be popular among users.  The wider Clinical Indicators team are currently undertaking an options appraisal for standardisation, and our plan is to resume publishing readmissions indicators by the end of 2018.

Finally, in response to feedback highlighting the need for indicators to be properly catalogued and indexed, we recently released an 'Overall list of Clinical Indicators' list.  This list is published under the 'Overview' section at and can easily be filtered to show only compendium indicators.


NHS Digital's "Compendium" is a collection of indicators, giving a comprehensive overview of population health at a national, regional and local level. 

The indicators within the Compendium can be useful for:

  • comparing the profile of your local area with other regions and national averages 
  • understanding what the population health challenges are in your area and how they may be changing over time 
  • exploring the diverse range of factors that influence health inequalities

The Compendium covers a wide range of indicators:

Cancer incidence, prevalence, survival and screening

  • Hospital care
  • Mortality
  • Public health
  • Local Basket of Inequality Indicators (LBOI)
  • Other (Area classification including deprivation, education, population, social care and socio-economic factors)

Why your views matter

This consultation is inteneded to gather feedback on proposed changes to:
