Comparing population estimates for drug users, the prevalence of blood-borne viruses and the provision of services in one London borough: Evidence of a gap in provision?

Abstract

Abstract:Aims To estimate the size of the drug using population in Lambeth, an inner city London borough, and the prevalence of blood borne virus (BBV) infections in the drug using population. To identify possible shortfalls in service provision for drug users. MethodsDirect and indirect estimates of the drug using population size using national and local data sources. Prevalence estimates for BBV infections were derived from local survey data. Routine data and a survey of borough services for drug users were compiled. FindingsBased on indirect methods we estimate there were 3117 drug users in Lambeth in 2001/2 (20 per 1000 15-44 year olds), of whom 1641 were injecting users (11 per 1000); 1353 were reported as being in drug treatment programmes. BBV prevalence rates: hepatitis B, 37%; hepatitis C, 71%; HIV, 6%. Estimated demand for needle exchange services, in terms of one syringe per injection, and methadone maintenance may be up to double local provision. ConclusionsMore accurate and feasible methods are needed for the routine estimation of the population of drug users. Accurate information is needed for service planning.
