Indicators↑ Contents

Indicator selection in the PHOF↑ Contents

Detailed criteria were used to select indicators for inclusion in PHOF. These are set out in the table below.

Essential [required for all indicators]

Clarity

it is clear what it measures, outcomes or activities

Rationale

it addresses a specific policy issue or draws attention to a particular outcome

Relevance

it is relevant to the policy and there is action available to improve

Attributable

it measures progress attributable to the interventions or activities

Interpretation

it is meaningful to the intended audience(s)

Validity

it has an unambiguous definition, is methodologically and technically sound from a reliable data source which is available at an appropriate level (for example local authority or integrated care board (ICB)) to make it meaningful and sustainable

Construction

the methods used support the stated purpose of the indicator and there is transparency about how they have been tested

Risks

any limitations, risks or perverse incentives are identified and stated with any mitigating actions

Availability

it is collected at sufficient level of geographical or organisational split

Affordability and value for money

it benefits without disproportionate costs and where new burdens are created these will be estimated, as well as sustainable funding identified

 

Desirable [wherever possible]

Timeliness                                   

it is possible to update with sufficient frequency (ideally quarterly) and data time lag (ideally less than one year but may vary for surveys)

Comparable

suitable UK or international metrics are available for making meaningful direct or proxy comparisons

Disaggregates

there is potential to break down by equality and inequality characteristics to measure impacts on different groups

Supports alignment

it is used across the health and care system via the other outcome frameworks.

How to interpret indicator values↑ Contents

All indicators require context in order to understand them. In general, the indicator values are somewhat abstract, and don’t mean much to anyone unless they are presented in comparison to other values of the same indicator. The Fingertips platform that is used to present PHOF indicators shows:

  • changes over time for most indicators, with a clear indication of whether the indicator values are rising or falling, and whether that change is ‘good’ or ‘bad’
  • indicator values for different areas alongside each other, showing an area in the context of other areas’ values
  • indicators alongside comparator values, such as national or regional averages, targets or benchmarks, and highlights differences between local values and the selected reference value using red-amber-green (RAG) ratings

OHID has produced a range of technical guidance to aid the interpretation of indicators and comparators.

Sources of data for PHOF indicators↑ Contents

Indicators in the PHOF use existing data sources wherever possible. The data source for each indicator is set out in the definitions tab.

Indicators are only shown in the tool where there are data available for them. All indicator data that is contained in the webtool is available to download from the download tab and metadata for the data download is available.

The fingertipsR package allows you to download public health data using R and the Fingertips API (Chrome only) allows public health data to be retrieved in either JSON or CSV formats.

Inequalities↑ Contents

Most indicators in the PHOF have the potential to impact on inequalities. We aspire to make it possible for all indicators to be disaggregated by equality characteristics and by socioeconomic analysis wherever possible. This is intended to support work locally to reduce in-area health inequalities where these persist. There is a list of inequalities data for each indicator and the data can be accessed from the Inequalities data view.

Data display↑ Contents

Information about areas↑ Contents

Where possible, indicators in the PHOF are presented at the following levels:

  • counties and unitary authorities
  • districts and unitary authorities
  • regions (statistical)
  • integrated care boards
  • NHS regions
  • England
  • combined authorities
  • local authority based deprivation deciles

Details of which geography level is presented for each indicator is available.

Values for City of London and Isles of Scilly local authorities are not included when calculating the highest and lowest values for England that are used in the spine charts in the Area Profiles view. The reason for this is that for many indicators, these values can artificially skew the distribution of values in England. They are therefore excluded to give a more representative range of values.

The England best and worst values are not displayed (and the spine chart is absent) in the Area Profiles view if more than 25% of local indicator values are not presented.

Colour shading↑ Contents

For many indicators, the way that the colour is assigned is based on statistically significant differences from the England value. This is determined within the PHOF tool by using the England or region value depending on the benchmark selected and seeing whether this lies within the confidence interval of the local value in question. For some indicators, there is a set goal (for example, 90% for many of the immunisation indicators). If a local value meets this goal or not determines their colour.

When not using the RAG rating, the colour of the indicators are:

  • blue when it is not straightforward to determine whether a high value is good or bad
  • white when they do not have confidence intervals with 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

Recent trends markers↑ Contents

At this stage we have only implemented a simple chi squared test for trend. For this to be a valid test for a statistically significant trend in an indicator, it needs to meet the following:

  • there must be at least five consecutive data points
  • the data points must be non overlapping, for example single years rather than three year rolling averages, and
  • the indicator must be a proportion or a crude rate

When there are at least five consecutive non overlapping data points available for a proportion or crude rate indicator, a chi squared statistical test for trend is carried out on the most recent five points. If a statistically significant trend is present, a red or green arrow is shown next to the indicator. If there is no significant trend in the most recent five points, the test is redone, including an additional (sixth) point, and so on, going further back until the full series has been tested. For more information, visit the Trend markers - technical specification for users.

Box plots↑ Contents

The box plot is a standardised way of displaying the distribution of data. In the Fingertips profiles we have displayed the 95th percentile, 75th percentile, median, 25th percentile, and 5th percentile in chart format, as well as the minimum and maximum values in table format, for each indicator.

Supporting data↑ Contents

Slope index of inequality in life expectancy↑ Contents

Life expectancy at birth and Healthy life expectancy at birth for each deprivation decile in England is available in the data download. 

Also available is a guide to the slope index of inequality method for PHOF overarching indicators and a link to the ONS data and briefing for A02c (local level healthy life expectancy slope index of inequality).

Slope index of inequality data for 2016 to 2018 onwards have been calculated using the Index of Multiple Deprivation 2019. A summary report and set of charts have been produced to assess the impact of using the Index of Multiple Deprivation 2019 rather than the Index of Multiple Deprivation 2015 for this time period:

Obesity and excess weight↑ Contents

Supporting indicators for the excess weight in adults (aged 18 and over) data in the PHOF are available. Breakdowns of local authority prevalence data by BMI category (underweight, healthy weight, overweight, obese, severe obesity and excess weight) are presented in an Excel spreadsheet: .

Trend data is available for small areas and health geographies on the prevalence of excess weight (overweight including obesity) in children from 2010 to 2011 to 2017 to 2018 and obesity from 2008 to 2009 to 2017 to 2018. Data from the National Child Measurement Programme (NCMP) is presented for Middle Super Output Areas, Electoral Wards, and Clinical Commissioning Groups (CCG).
