  1. World Class Commissioning Inequalities Indicator Slope Index of Inequality Dave Jephson, Public Health Analyst, EMPHO

  2. Background • In the 2008 World Class Commissioning (WCC) Framework contained 2 compulsory indicators – Life Expectancy and Index of Multiple Deprivation (IMD) • The IMD indicator was criticised on the grounds of: - Not routinely updated, and when updated, the definition had changed - Most of the components of the IMD are beyond the PCTs sphere of influence - It was a national level indicator, allowing PCTs to be compared to others, but not looking at inequalities within PCTs

  3. Reviewed for 2009 • Department of Health (DH), in response to feedback decided a change of indicator was necessary • DH asked APHO (represented by LHO as lead on Health Inequalities and EMPHO who had recently completed review of methods of measuring inequalities with Derbyshire PCT) to recommend an indicator for 2009 • APHO proposed the Slope Index of Inequality for Life Expectancy at birth (separately for males and females), using grouped data for deciles of deprivation within the PCT (5 year grouped data) • DH agreed and APHO produced the indicator

  4. How do I calculate the Slope Index?Stage 1 – Life Expectancy by decile Individual Level Mortality Data Use postcode lookup LSOA Level Population Data, by age and sex (provided to PHOs by ONS) LSOA Level Mortality Data, by age and sex Use IMD scores to group LSOAs within a PCT into deciles PCT Deprivation Decile Population Data, by age and sex PCT Deprivation Decile Mortality Data, by age and sex Use published SEPHO Life Expectancy Calculator PCT Deprivation Decile Life Expectancy Data, by sex

  5. How do I calculate the Slope Index?Stage 2 – Get the chart data Example – Made-up PCT (Males)

  6. How do I calculate the Slope Index?Step 3 – Plot the data and get regression line Slope is the LE value of the line at 100% - LE value of the line at 0%

  7. Having said all that… • Go to the APHO website - http://www.apho.org.uk/resource/view.aspx?RID=75050 • Contains a lookup showing which LSOAs are in which decile • Contains spreadsheets with Life Expectancy data by decile, and slope index values for 2001-5, 2002-6, 2003-7 and recently updated with 2004-8 • Contains charts showing the data plotted for 2003-7 and 2004-8 • Contains ‘Guide to interpretation’, ‘Guidance on setting trajectories’ and the full APHO recommendation for the indicator

  8. Trajectory setting advice • As the indicator is based on five years’ aggregated data, the extent to which the indicator is likely to change is small • For most PCTs, it is expected that the SII will not increase or decrease by more than 10% from one five year period to the next. • PCTs are encouraged to aim high, and set ambitious targets “as a means of stimulating and encouraging increased levels of improvement in health” • The national target for LE inequalities is to reduce the gap by approximately 1% per year. • Local trajectories of this order may be appropriate
