Background: Depression is common in nursing-home patients and is often of chronic nature. Aims: To examine the prevalence, incidence and the persistence rates of clinically significant depressive symptoms, and their risk factors among nursing-home patients.
Design: A 12 months follow-tip study.
Methods: A sample of 902 randomly selected nursing-home patients was assessed using the Cornell Scale, the Clinical Dementia Rating Scale, the Self-Maintenance Scale and a measurement of physical health. Information was collected from the patients' records. Clinically significant depression was defined as 8+ on the Cornell Scale.
Results: At 12 months 231 had died, and depression was together with higher age, worse physical health, poor function in activities of daily living, higher CDR score and cancer a significant predictor of death (0.03). The prevalence of depression was 21.2% at baseline and follow-up, incidence rate was 14.9% and persistence rate was 44.8%. Predictors of depression at 12 months were: high Cornell score at baseline (p<0.001), a shorter stay in a nursing home (0.011) and use of antidepressants (p = 0.050): for incident depression: higher Cornell score at baseline (p = 0.019), a shorter stay (p = 0.002) and higher CDR Score (p = 0.003); for persistent depression: higher Cornell score at baseline (0.011), use of anxiolytics (p = 0.045) and not being married (p = 0.037).
Conclusion: The incidence and persistence rates of clinical significant depressive symptoms are high in nursing-home patients. A higher score on Cornell Scale at baseline and a shorter stay in a nursing home were predictors for both incidence and persistence of clinically significant depressive symptoms.
