Frequently Asked Questions

What geographies can I view?

Data are presented for Upper Tier Local Authorities and England, former Government Office Regions and where available Lower Tier Local Authorities.

How do you convert data collected at DAT (Drug and Alcohol Treatment Team)  level into indicators for local authorities?

The metadata for the indicator which has been converted from Drug and Alcohol Team level to Local Authority level describes in detail how this is done. This applies to the following indicators:

Will you publish data for District Councils?

Due to the nature of the indicators, and the inherently small numbers involved (particularly for non-alcoholic fatty liver disease (NAFLD) and the hepatitidies), we are unable to produce reliable, robust analyses to populate the indicators at the Lower Tier (District) Level.

How can I compare my area to other local authorities?

In the data tool, it is possible to compare your local authority with others in the same region, Public Health England Centre or deprivation decile in the Overview tab. Other comparators may be added in future. Please let us know if you have any specific requirements.

How were indicators selected for the Liver Disease Profiles?

Detailed criteria were used to select indicators. They were developed in collaboration with expert input from stakeholders, epidemiologists, clinicians and professionals in alcohol, drugs, hepatitis and obesity, to provide a comprehensive means of assessing the suitability of each candidate indicator. These were used to assess the final set of indicators including those suggested in response to the consultation exercises.

What are Official Statistics?

Updates to the Public Health Outcomes Framework data tool are published as official statistics. They are produced in accordance with best practice set out in the Code of Practice for Official Statistics for example, to ensure that they are fit for purpose, methodologically sound, politically independent and produced in a transparent way.

Why are some indicators presented as Higher/Lower than the benchmark and shaded blue, instead of Better/Worse and shaded Red Amber Green?

Indicators that are shaded blue rather than Red/Amber/Green are presented in this way because it is not possible/appropriate to apply the explicit value judgement inherent in the "Better/Worse" system. For example the 'Percentage of people who inject drugs indicator', is an artefact of the population demographics (a measure of population at risk), of the particular Local Authority, and is not a measure of performance as is implied by the Better/Worse system. Indicators that are shaded white are presented in this way because they do not have confidence intervals associated with them by which to compare against the benchmark value, and therefore it is not possible to determine whether the local value is statistically significantly higher or lower than the benchmark.

How do you determine the colour of areas for particular indicators in the tool?

The way that the colour is assigned is based on statistically significant differences from the England value. This is determined within the Liver Disease Profiles tool by using the England value, and seeing whether this lies within the confidence interval of the Local Authority in question.

Who is responsible for collating and publishing Liver Disease Profiles data?

Responsibility for collating and publishing indicators is Public Health England, Knowledge and Intelligence Team (South West).

What are the sources of data for Liver Disease Profiles indicators?

Indicators in the Liver Disease Profiles have been based on existing data sources wherever possible. The data source for each indicator is set out within the definitions tab.

Can I re-use the data and charts in my own work?

You can use and re-use the data and charts from the Liver Disease Profile tool (not including logos) free of charge in any format or medium under the terms of the Open Government Licence. To view this licence in an offline capacity write to the Information Policy Team, The National Archives, Kew, London TW9 4DU, or e-mail: psi@nationalarchives.gsi.gov.uk. Please state that you obtained the information from the National Liver Disease data tool in your published document.

How can I find more detailed information for my area?

More information is available for different health related topics and for smaller geographical areas. See www.localhealth.org.uk for profiles of your electoral ward, click here or click the 'Further Info' tab for more health profilling tools.

How can I influence what indicators are included in the Liver Disease Profiles in future?

Please let us know  if you would like to provide comments on the profiles or be involved in their further development.

Why is the 'Persons starting HCV treatment indicator not in the data tool?

Indicators are only shown in the tool where there are data available for them. Currently no data is available for this indicator. It is a 'placeholder' indicator in the pdf profiles, demonstrating to Local Authorities the importance of this indicator, but the fact that there is currently no data available to populate it.
