Depression in schizophrenia: recognition and management in the USA.
The recognition of depression as a distinct syndrome within schizophrenia is a relatively recent development. The International Survey of Depression in Schizophrenia was designed to evaluate current clinical practice and prescribing trends in the management of the depressive component of schizophrenia. A 48-item questionnaire, comprising fixed-response questions and questions stimulated by case scenarios, was distributed to 37513 psychiatrists in the USA. A total of 43484 psychiatrists in Canada, Australia and 21 European countries also received the questionnaire. A total of 1128 US psychiatrists responded. Analysis of the data revealed that US psychiatrists identify symptoms of depression in approximately one-third of patients with schizophrenia, and largely appreciate the magnitude of the resultant burden on patients and their families. Responses to questions regarding treatment approaches and case scenarios demonstrated that the level of adjunctive prescribing of antidepressants in the USA is often higher than in other regions. Levels of awareness of depression in patients with schizophrenia and recognition of the need for effective management appear to be high among US psychiatrists. However, more than a quarter of these specialists rarely or never prescribe adjunctive antidepressant medications. Disparities in treatment approaches varying from the existing scientific evidence base underscore the need for further investigation into ways of optimizing the management of this serious coexisting condition.
