# Integrated Care Board peers

****

**Aim:**

Identify which ICBs are ‘alike’ based on various characteristics

**Method:**

2-stage approach was used:

1. Each variable is validated and standardised by:

a) Capping each variable value at 5 standard deviations over the mean – to avoid

outlier effects.

b) Taking square root of all values – to reduce skew

c) Subtract mean and divide by the standard deviation (of square-rooted values)

2. A calculation of similarity (Euclidean distance) is then completed - this uses the standardised variables for two ICBs in each pair from the first stage of this approach and the weights associated with each variable. This produces a distance matrix, ranking the similarity distance between each ICB The similar ICBs are those with the lowest value in this matrix. The closest 5 to each ICB were chosen as the suggested set of peers.

**Variables included in model Development:**

•
Deprivation

• Population

• Adult population age groups (18-39, 65-84, 85+)

• The percentage of population with Rural/Urban residence

• The percentage of population by ethnicity (White British, Non-British, Mixed,
Asian, Black, Arab or Other)

To produce the aggregated ICS level data, where the variable was a proportion,
a weighted average was calculated. This averages the CCG level data while also
considering the proportion that the CCG’s population makes up of the overall
ICS population.

**Data sources:**

• The
average Index of Multiple Deprivation (2019) score in the LSOAs where CCGs'
registered patients lived in April 2019

• The total population registered with CCGs' practices (April 2020)

• Adult population age groups (18-39, 65-84, 85+) in CCGs

• The percentage of people who said they are of white (non-British) ethnic
origin (GP Patient Surveys 2017, 2018 and 2019)

• GP Patient Surveys 2017, 2018 and 2019)

• Percent of population who live in areas defined by the ONS Rural Urban
Classification as "Rural town and fringe in a sparse setting",
"Rural village and dispersed" or "Rural village and dispersed in
a sparse setting" (April 2018))

**Primary Outcome:**

Lists of 5 peers for each ICB.

**Secondary output:**

Output imported onto Model Health System dashboard to support benchmarking and opportunity estimations.
