Results from the 1995 survey of prevalent clinically diagnosed HIV infection in England, Wales, and Northern Ireland.

Health districts in England, Wales, and Northern Ireland were surveyed in 1996 to collect summary information about people with diagnosed HIV infection who received care under the statutory services in 1995. The survey provided demographic and epidemiological information about the prevalent caseload by area of residence, and the extent to which patients with diagnosed HIV infection travelled to obtain care related to it. A total of 13362 people with diagnosed HIV infection were reported to be resident and treated in England, Wales, or Northern Ireland in 1995. Forty-four per cent of these were treated outside the health district where they lived, with regional specialist centres attracting patients from wider areas. At least 13% received care from more than one treatment centre. This national survey of prevalent diagnosed HIV infections provided public health specialists with information relevant to their own localities without compromising confidentiality. This information complements surveillance data from confidential AIDS case diagnosis reports, laboratory reports of HIV infections, and the unlinked anonymous HIV prevalence monitoring programme, all of which contribute to the assessment and projection of demands on health and social services, and provide evidence on which to develop and direct national and local health campaigns.
