Depression is frequent in populations of elderly. Methodological differences between the studies hinder consistent conclusions about geographical and cross-cultural variations in prevalence and predictors of depression. Improved comparability will provide a basis for consistent conclusions.

An ICD-10 diagnosis of depressive disorder or dysthymia predicted increased use of psychiatric services, more psychiatric diagnoses and increased mortality, indicating poor late-life psychiatric outcome. Contrasting with other studies, depression did not predict increased use of somatic hospital services or more somatic diagnoses. The differences in health care status and use between elderly living in the capital and in rural areas elderly are novel findings.

The objectives of this report were to investigate the functional implications and the possible rehabilitation potentials of dementia, delirium, and psychosis in elderly inpatients, compared with that in depression. During 1 year, all patients in a psychogeriatric university clinic were assessed on admission and at discharge with a selection of rating scales and diagnosed according to ICD-10 by consultants with no knowledge of the results of the ratings. All patients who had a principal diagnosis of major depression, dementia, delirium, or a psychosis are discussed. Ratings were made for psychopathology, behavioral disorders, depressive statements, intellectual functioning, activities of daily living, and gait. Depressive and delirious patients improved their status significantly (p ≤ .03) in all six assessments, and patients with dementia improved their psychopathology status (p = .002), but the other assessments were unchanged. Results from the small sample (n = 8) of psychotic patients were mainly inconclusive, but there was a tendency for improvement with respect to psychopathology and gait.

The study aims to establish the predictive value of a diagnosis of depression among elderly according to the 10th revision of the International Statistical Classification of Diseases (ICD-10) by measuring morbidity, medication usage, health service utilization and mortality during an 8-year follow-up of depressed elderly inpatients (n=76) and community-living depressed patients (n=38) compared with controls (n=116). The data were taken from GPs' medical records and health statistics registers. At baseline, no significant differences were observed between the two cohorts of depressed patients and the controls in terms of prevalence of cardiovascular, respiratory or cerebrovascular morbidity. During follow-up, both cohorts of depressed patients had significantly increased rates of recurrent depressions, consumption of antidepressants, psychiatric in- and outpatient admissions, and home visits; inpatients used more psychiatric hospital days. Health service utilization in somatic hospitals and somatic diagnoses was not significantly increased. Inpatients used significantly fewer GP office-hour services but more out-of-hours services than the control group. Community-living depressed patients experienced no significant increase in use of GP services. Survival was unaffected in both cohorts. In agreement with other studies, especially inpatient depression predicted increased rates of recurrent depressions and increased use of psychiatric hospital services, indicating poor long-term outcome. Inpatients consumed fewer GP office-hour services but more out-of-hours services, possibly due to less office-hour contact. Contrasting with other studies, ICD-10 depression among elderly predicted no increase in the use of somatic hospital facilities.
