摘要：
Background: Depressive disorders are overrepresented among patients admitted to nonpsychiatric units of general hospitals, but the majority of depressed patients are not identified in this setting. Effective and well-tolerated treatments and reliable diagnostic criteria, together with new assessment tools (self-administered or not), have been developed with encouraging results. Nevertheless, few studies have utilized standardized instruments and extensive clinical interviews by well-trained psychiatrists to assess depression. New research should test these tools in a French-speaking environment. Methods: The investigation covered 292 patients aged 18-65 who were admitted over a period of 6 months to the internal medicine units of Geneva University Hospitals. Each patient filled in a self-administered questionnaire for depression [Patient Health Questionnaire (PHQ-9)];212 patients were also evaluated by a psychiatrist using DSM-IV diagnostic assessment and the Hamilton Depression Rating Scale during the first week of their hospital stay;both assessments were single-blinded. Results: Psychiatric clinical interviews identified a high proportion (26.9%) of depressive disorders (37% among women) for all diagnoses;11.3% (17.3% among women) of the patients met the DSM-IV criteria for major depression. The PHQ-9 identified depressive disorders among 34.9% of patients (42% among women) and identified a major depressive syndrome among 18.4% of patients (29.6% among women). Physicians in the internal medicine unit identified only about half the depressive patients;at the time of psychiatric examination, fewer than one in four patients was receiving antidepressant therapy. Conclusions: Our findings confirm the results of previous investigations, which showed that the failure to detect and treat depression is a major health problem among patients admitted to nonpsychiatric units of a general hospital.
