Objectives: The authors' aims were to explore prevalence of anxiety among patients admitted to departments of geriatric psychiatry for treatment of various diagnoses and to examine how often anxiety was registered as a previous or ongoing diagnosis. Method: In all, 473 patients admitted to one of five departments of geriatric psychiatry were included in a quality register and examined according to a standardised protocol. The Geriatric Anxiety Inventory (GAI) was used to measure anxiety during the first week after admission. Diagnoses were made at discharge. Results: Using a cutoff on the GAI of 8/9, the prevalence of anxiety for the following diagnostic groups was depression 65.3%, psychosis 28%, dementia 38.8% and mania 33.3%. Of 24 patients with a primary diagnosis of anxiety, 66.7% scored above 8 on the GAI. Of 236 patients with a GAI score above 8, only 22 (9.3%) were reported to have a comorbid anxiety disorder by the treating psychiatrist. In a multiple regression analysis, we found that the severity of depression (beta 0.585, p < 0.001), being female (beta 0.096, p 0.028) and the use of antipsychotic drugs (beta 0.129, p 0.006) and anxiolytic drugs (beta 0.129, p 0.005) were associated with a higher GAI score. Conclusion: Anxiety is common in geriatric psychiatric patients, regardless of the primary diagnosis. The findings suggest that anxiety is often a hidden comorbidity in various psychiatric disorders. A high score on the GAI was associated with the severity of depression, female gender and the use of antipsychotic and anxiolytic drugs. (Edited publisher abstract)
