RESUMO
OBJECTIVES: The goal of this study was to assess the level and analyze the determinants of under-recognition of symptomatic depression by geriatricians in hospitalized geriatric patients. METHODS: This was a prospective study of 155 patients who were consecutively hospitalized in the geriatric unit of an academic hospital. The diagnosis of symptomatic depression was established, in a parallel blinded manner either by one psychogeriatrician using a geriatric depression scale and the DSM-IV criteria for depression or by one geriatrician using a global assessment score included in a comorbidity index or by both. RESULTS: The psychogeriatrician diagnosed symptomatic depression in 67 of the 155 patients (43%). In contrast, the geriatrician identified symptomatic depression in 29 (19%) of the 155 patients, one of whom was not diagnosed with depression by the psychogeriatrician. Thus the geriatrician failed to identify 39 patients who were diagnosed with depression by the psychogeriatrician. CONCLUSIONS: In this study of hospitalized geriatric patients, a geriatrician failed to recognize more than half of those who were diagnosed with symptomatic depression by a psychogeriatrician. Uncontrolled comorbidity and therapeutics may be misleading factors in diagnosing depression. The presence of a psychogeriatrician in a geriatric unit could prevent underestimation of depressive symptoms among geriatric patients.
