Data are presented for upper tier local authorities and England, regions and where available lower tier local authorities and integrated care boards.
The metadata for the indicator which has been converted from DAT level to local authority level describes in detail how this is done. This applies to indicator 90883 - percentage of people who inject drugs, aged between 15 and 64 years
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.
In the profile, it is possible to compare your local authority with others in the same region, or deprivation decile by selecting 'Overview' under the 'Data view' dropdown menu. Other comparators may be added in future. Please let us know if you have any specific requirements.
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.
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.
Indicators that are shaded blue rather than red, amber or green are presented in this way because it is not possible or appropriate to apply the explicit value judgement inherent in the 'better' or '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' or '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.
The way that the colour is assigned is based on statistically significant differences from the England value. This is determined within the liver disease profile tool by using the England value, and seeing whether this lies within the confidence interval of the local authority in question.
Responsibility for collating and publishing indicators is with the Office for Health Improvement and Disparities (OHID), Public Health Analysis Unit.
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.
You can use and reuse 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. Please state that you obtained the information from the 'Office for Health Improvement and Disparities (OHID) liver disease profile' in your published document.
More information is available for different health related topics and for smaller geographical areas within fingertips. Links to other statstical resources published by OHID are available from the
statistics at OHID webpage.
Please let us know if you would like to provide comments on the profiles or be involved in their further development.
