a
Adapted from Turner et al.
b
A measure of relative deprivation for small areas; a higher score indicates more deprivation (range, 0-100). English and Welsh scores are not directly comparable; therefore, they are reported separately.
c
A system for the performance management and payment of primary care clinicians based on the quality of their care.
d
Based on data from 2007 and 2008.
e
Calculated as (No. of individuals registered with a health condition at each practice/total No. of individuals registered at each practice) × 100.
