Dual diagnosis in the suburbs: prevalence, need, and in-patient service use.
Previous research has found comorbid severe mental illness and substance misuse (dual diagnosis) to be highly prevalent and to be associated with serious clinical and social problems, and increased service use in inner-city populations. The present study measures the prevalence of dual diagnosis, patterns of substance misuse, and associated in-patient use in a more demographically representative population in a suburban area of South London. ⋯ The prevalence of substance misuse in patients with severe mental disorders in a suburban area is about as high as that for similar patients in inner-city London. While DD patients are not admitted more often than patients with psychosis alone, they have double the length of in-patient stay, which may be attributable to higher levels of unmet need.
