Old age medical patients screening positive for depression.

Objective: The aim was to observe whether medical inpatients screening positive for depression using the Geriatric Depression Scale (GDS) continue to screen positive following hospital discharge.

Method: Participants aged 65 or over, were recruited from consecutive admissions to a city teaching hospital. Subjects had an Abbreviated Mental Test Score (AMTS) of seven or above and a GDS-15 score of five or above. Information was collected on past psychiatric history and living arrangements. Subjects were followed-up three months later and the GDS repeated.

Results: Thirty subjects were recruited and 26 (87%) followed-up. Ten (38%) no longer scored positive on the GDS, and overall the mean GDS score decreased by two points (Z = 2.235 p < 0.05). Patients with a past psychiatric history or living alone were more likely to be depressed at follow-up. No participants were referred to the psychiatric service or started on antidepressant medication during the course of the study.

Conclusion: Depressive symptoms are likely to persist following hospital discharge, especially in those patients with a past psychiatric history. An understanding of the risk factors associated with persistent depressive symptoms is necessary if the patients appropriate for treatment are to be identified.
