Schizophrenia sans frontieres: concepts of schizophrenia among French and British psychiatrists.

Abstract

Objective-To compare the first admission rates for schizophrenia in Conclusions-British and French psychiatrists use different diagnostic criteria and contrasting methods oftreatment for schizophrenia. Differences in diagnostic criteria probably contribute towards the disparity in administrative incidence rates and time trends for schizophrenia in the two countries. Doctors in the European Community can now work in any country. Further work is needed to ensure psychiatrists are talking a common language.

A systematic review of the incidence of schizophrenia: the distribution of rates and the influence of sex, urbanicity, migrant status and methodology

“…The 158 included studies were drawn from 32 countries. One study [13] provided rates for seven countries, and another provided rates for two countries [74]. Details of these studies are shown in Table S1 in Additional File 4.…”

“…Of the included studies, 13 included at least one rate with person years as the denominator [9,21,31,42,74,93,121,130,133,152,163,167,174]. Person-year incidence rates have been used in descriptive and model-based analyses alongside crude annual rates.…”

“…Of the 1,457 rates in the included studies, 501 (34.4%), from 42 studies, employed age-standardization: [13,31,35,45,46,50,56,68,74,76,80,88,91,102,107,109,110,115,116,118,124,127,128,130,133,135-138,141,142,144-150,168,181,187,188]. As with person-year incidence rates, age-standardized rates have been used alongside crude rates.…”

Patterns of drug treatment of schizophrenic patients in Estonia, Spain and Sweden.

“…Different concepts about diagnosis and treatment among psychiatrists in different countries are well known [19]. Schizophrenia was chosen as a study diagnosis, because it is generally regarded as having similar incidence between different cultures and times [15,16].…”

Evolutionary psychiatry and the schizophrenia paradox: a critique

“…Indeed, an ambitious international investigation, the US/UK Diagnostic Project (Cooper et al 1972), revealed that American psychiatrists made the schizophrenia diagnosis twice as much as their colleagues from Britain, even though both teams made use of identical diagnostic criteria. And as late as 1993, it turned out that French and English psychiatrists were still using substantially different concepts of schizophrenia (Van Os et al 1993).…”
