Natural history of pharmacotherapy of older depressed community residents. The MRC-ALPHA Study.

BACKGROUND

Depression in older people is common and has a high mortality, but effective treatments exist.

AIMS

To describe drug prescribing in older community residents in relation to depression status.

METHOD

The MRC-ALPHA community cohort aged 65 and over were interviewed using the Geriatric Mental State examination drug data collected at index interview and at two and four years.

RESULTS

Antidepressants were used by 10.9% of the depressed population. Benzodiazepines were used frequently. Of the antidepressant users, 59.6% took low-dose antidepressants for two years, had a poor outcome and few drug changes.

CONCLUSIONS

Trends of increasing antidepressant use have cost implications for primary care groups. Benzodiazepines may be mis-prescribed for treatment of depressive symptoms. Antidepressant users have poor outcome and follow-up.
