[Typology of elderly patients hospitalized in psychiatry: evaluation of psychiatric antecedents before age 60]

Abstract

To take care of elderly patients in psychiatric hospital sets specific problems. It is interesting to know the mode, the frequency, and the reasons of these hospitalizations, to improve the medical care given to these subjects. We made a prospective study with elderly patients hospitalized in a psychiatric institution. The results were completed in discussions with the medical care staff. During the study (January and February 1997), 112 elderly patients, about more than 60 years old, were hospitalized in Villejuif' specialized hospital (inpsychiatric units). Informations about social facts, main psychiatric previous, reasons of the hospitalization, the caring and the evolution of these subjects were collected. The main important reflexion we did observe was the significant difference between elderly patients hospitalized in psychiatric units, with or without psychiatric previous before the age of 60. Those who were hospitalized at the first time in psychiatric units before 60, presented a medium aged population, younger than the other group. They also presented more delusion with psychosis, were more frequently hospitalized longly in psychiatric units, took neuroleptics, and their somatic associate pathologies were less difficult to take care of. In the second group including the elderly patients without psychiatric previous before 60, we did observe very different characteristics: the diagnosis of most of the patients is dementia; these elderly subjects leaved mostly at home, they presented more sadness, aggression, or social inappropriate behaviour. Depression is a more frequent diagnosis. This study of all the elderly patients admitted in a psychiatric hospital confirmed the population's heterogeneity. The existence of an hospitalisation in psychiatric unit before sixty represented a pertinent test to a major and simple approach of these differences. The psychiatric unit which receives more and more elderly patients take care of their differences to the organisation of care needs between the gerontopsychiatric patients types. The patients with a late gerontopsychiatric's disease could need a specific hospitalization in gerontopsychiatric units, especially organised to deliver psychiatric cares and somatic cares, including medical geriatric practicer and medical care staff formed to the dependence need care.
