Inequality in unplanned hospitalisation for chronic ambulatory care sensitive conditions

Why this fact is important:

This measure shows how much higher the rate of unplanned hospitalisation for chronic ambulatory care sensitive conditions is in the most deprived areas of a CCG compared to the least deprived.

Things to note:

The rates have been adjusted to take account of the age and sex mix of the population in a CCG. Therefore the differences are not simply because deprived and less deprived areas have an older or younger population.

A higher value indicates a higher difference between more- and less- deprived areas. The "underlying CCG mean values" are the adjusted CCG rates of unplanned hospitalisation for chronic ambulatory care sensitive conditions.

This is the absolute gradient of the relationship at Lower Super Output Area (LSOA) level between emergency admissions for chronic ambulatory care sensitive conditions per 100,000 population and deprivation, measured by the Index of Multiple Deprivation (2015).

The indicator measures the reduction over time of within-CCG variation in emergency admissions for chronic ambulatory care sensitive conditions. Variation is measured by the gap between more and less deprived Lower Super Output Area (LSOA) rates of emergency admissions for chronic ambulatory care sensitive conditions per 100,000 population. The measure uses the range of deprivation in England as a whole, which allows direct comparisons to be made between all CCGs.

The results can be interpreted as 'if my CCG had both the most and least deprived small areas in the country in it, then this is the difference in their admission rate'.

Interpretation of Results

Method of data analysis: The Absolute Gradient of Inequality (AGI) is calculated for each CCG by weighted least squares using the indirectly age-standardised rate of unplanned hospitalisation per 100,000 registered population as the dependent variable; the rank of IMD 2015 (on a scale of 0 to 1) as the independent variable, and the CCG’s population in each LSOA as the weight. The coefficient on the rank of IMD is the slope and is called the AGI.
