Characteristics of early-and late-diagnosed schizophrenia : implications for first-episode studies.
First-episode studies of schizophrenia are being carried out in many places.
However, previous work has suggested that only half of the patients with schizophrenia receive the diagnosis in the initial stages of the illness.
We examined whether cases of early-and late-diagnosed schizophrenia differed with respect to key sociodemographic characteristics and indicators of service use that might bias first-episode studies.
Individuals who (i) presented for the first time between 1983 and 1993 to psychiatric services in a defined urban area with a cumulative mental health case register ; and (ii) received a diagnosis of schizophrenia at least once during their mental health career were identified (n=186).
This sample was divided into those who received the diagnosis of schizophrenia for the first time within the first year of service contact (early-diagnosed schizophrenia ; EDS), and those who received it for the first time after the first year of service contact (late-diagnosed schizophrenia ; LDS).
The 10-year incidence of EDS and LDS were 10.4 and 7.0 per 100 000 person-years, respectively.
