The Independent Inquiry into
Inequalities in Health recommended that the needs of minority ethnic
groups are specifically considered in needs assessment, resource
allocation, and healthcare planning and provision (Independent Inquiry
into Inequalities in Health, 1998). The Inquiry also called for a review
of data requirements to improve the capacity to monitor inequalities in
health and their determinants at a national and local level. Predating
this recommendation the NHS introduced mandatory coding of patients'
ethnic group for admitted patient care in April 1995 for the purpose of
enabling "providers and purchasers to understand the needs of their
local population and to deliver more appropriate and more acceptable
services." (Information Management Group, 1994) However, there has
been little investigation into ethnic variations recorded by this new
field. Patients were to be classified using the 1991 census groups, thus
enabling comparisons to be made with resident populations. Admitted
patient care was deemed to be the only information system capable of
collecting, storing and retrieving ethnic group data, hence coding was not
extended to primary care.
3.1 The ethnic map of the West MidlandsThe following four figures display the ethnic population aggregated into the four major groups by Primary Care Group. The four major groups are composed thus:
The populations are based on the resident population at the 1991 Census. The populations have been constructed using the PCG boundaries as supplied by the West Midlands Cancer Intelligence Unit (WMCIU). Figure 3.1 Percentage of PCG Population who describe themselves as Asian Figure 3.2 Percentage of PCG Population who describe themselves as Black Figure 3.3 Percentage of PCG Population who describe themselves as from other ethnic groups Figure 3.4 Percentage of PCG Population who describe themselves as White 3.2 Quality of coding by Ethnic group across West MidlandsSince the introduction of the new field in 1995/6 the quality of coding has improved year on year and the level is now in excess of 70%. There remain however large variations in the quality of coding across trusts (see figures 3.6 and 3.7) Figure 3.6 Quality of coding across Acute Trusts measured as percentage of valid codes recorded. Figure 3.7 Quality of coding across Community Trusts measured as percentage of valid codes recorded. 3.3 Admissions rates by Ethnic group by Our Healthier Nation groupsPresented here are admissions to hospitals by residents of the West Midlands by ethnic group in 1997/8. In view of the errors in data capture these are illustrative of the type of variation observed across ethnic groups rather than a true measure of the rate. For each rate a 95% confidence interval has been calculated. Due to the problem of small populations the ethnic groups have been aggregated using the same groups as for Figures 3.1 to 3.4.
