The assessment of depression: a model for quality review of emergency psychiatry

Of 167 patients appearing in the psychiatric emergency room of a metropolitan hospital, 68 were categorized as significantly depressed by the Zung depression scale but only 43 were considered depressed by clinician-interviewers. The use of a patient self-rating scale, which in this setting permitted the identification of deficiencies in the recognition of depression, is applicable to quality review in a variety of clinical settings.
