This paper reports on a study of psychiatric morbidity in 920 patients attending 18 General Practitioners in Lewisham, South East London. Two indices of morbidity were computed on the basis of the patients responses to the General Health Questionnaire (GHQ) and the GPs' own estimates. Indices of the GPs' detection ability were found by comparing questionnaire and GP rating. The results are compared to those obtained by other workers in a sample of Manchester GPs. The GHQ gave a prevalence estimate of 42.9% which is comparable to that of 39.6% obtained in the Manchester study. In addition, the variation in caseness across sociodemographic groups was consistent with the Manchester findings. The GPs' estimates of morbidity, while much lower than those obtained in Manchester, have similar sociodemographic profiles. The results support the use of the GHQ as a screening device in epidemiological studies, and suggest the need for further investigation of the individual GP's performance as a case detector.

Length of stay is not predictive in the Cox regression model, which suggests patients are not being prematurely discharged. The derived models may have value in service planning, audit and resource allocation.

This paper describes a survey of British Community Mental Health Centres (CMHCs). CMHCs are by far the most visible manifestation of the implementation of community mental health care policies of the 1980s. While these centres have demonstrated achievements in terms of accessibility, co-ordination and responsiveness to clients, they have also been bedevilled by ambiguity. The vast majority of CMHCs aim to serve the needs of all forms of mental illness within their catchment area, yet in practice, they have frequently failed to meet the needs of people with long term severe disorders and concentrate instead on providing assessment and counseling services for neurotic and transient situational disorders. It appears that this is a function of an early failure of multidisciplinary teams to delineate boundaries and priorities. If the British CMHC movement sharpens its focus and combines this with a determination to address the complexities involved in both rationing and enhancing choice, it could begin to improve upon rather than simply repeat the history of similar developments in America.
