Collecting ethnic group data for inpatients: is it useful?

Since April last year British hospitals have had to collect data on the ethnic group of every patient. Patients must categorise their own ethnic group using the categories of the 1991 census. Claire Hilton argues that such data collection is unhelpful and will not meet its stated aim of helping to provide equitable access to NHS services for all ethnic groups. Self categorisation is unreliable, and the number of ethnic groups available is inadequate, in particular for the white population. Additional data on the size of each ethnic group in the local population and on rates of illness in particular groups are necessary to assess whether services are being provided equitably. Moreover, ethnicity is a multidimensional concept, and information on patients' language and cultural and religious practices, as well as their place of origin, is necessary if services are to be culturally sensitive.
