To know prevalence of depression in Spanish nursing home(NH) by analysing the clinical profile of residents from RESYDEM study (Identification of patients with cognitive deterioration and dementia in NH).

A multicentral, transversal, observational study was carried out in April 2005. 71 geriatrician from 54 NH representing the Spanish state participated. Depression was analysed in patient´s history and determined by NPI of Cummings, NH version.

1037 residents were randomized, 1020 were used by clinical data analysis. 941 were used to determine depression prevalence. Median age 83,4yo, 66.6% were women, 70.9% with basic educational level, 57.4% widows, 25.7% single, 41.5% had some degree of functional deterioration, 22.1% had delirium. In 26.4% were documented Stroke(17,9% TIA). 61.7% had dementia.

Depression appears in 31.4% of elderly institutionalized with the only diagnosis of depression or independent of others. There were no significant differences in age groups. However, was most frequent in women. 95.7% of patients with diagnosis of dementia had at least one drug for depression. Most used anti-depressants were trazadone (23%), citalopram (20.9%), sertraline (15.8%), fluoxetine (10.1%). No tricyclical anti-depressant reached 1% of consumption.

Depression affects practically one in three institutionalized elderly in Spain

Institutionalized elderly with depression are largely treated with ISRS. It is believed that the use of trazadone is linked with the effects on sleep and anxiety.

The high prevalence of depression, its overlapping with other processes and the comorbility of residents requires a careful search and approach in NH which implies a challenge for professionals in order to treat it.
