[Revue des effets de l'institutionnalisation sur le développement de la dépression chez les personnes âgées résidant en maison de retraite].

Depression is a prevalent mental health issue among elderly people residing in nursing homes, with significant implications for quality of life. From an initial pool of 175 articles, seven met the inclusion criteria, including four longitudinal studies, two controlled trials, and one systematic review. The findings indicate mixed outcomes regarding the impact of institutionalization on the trajectory of depression, underlining the complexity of its support. A number of risk factors appear to be associated with depression, such as gerontopsychiatric disorders, functional impairment, chronic illness and gender. Interventions such as increased exposure to natural light and psycho-educational programmes could be relevant therapeutic tools. This review emphasizes the need for more robust longitudinal research, and uniform depression assessment methods to better manage depression at the entrance of the nursing home.
