Direct costs associated with depression in old age in Germany

Area of Science:

• Geriatric Medicine
• Health Economics
• Psychiatry

Background:

• Depression is prevalent in the elderly population.
• Limited research exists on depression's impact on direct costs in older adults, particularly outside the USA.
• This study focuses on the German advanced elderly (75+).

Purpose of the Study:

• To determine the effect of depression on direct healthcare costs in advanced elderly individuals in Germany.
• To analyze the societal perspective of these costs.

Main Methods:

• A face-to-face investigation of 451 primary care patients aged 75 and older.
• Assessment of depressive symptoms using the Geriatric Depression Scale (GDS).
• Evaluation of chronic medical illness using the Chronic Disease Score and resource utilization via cost diaries, with costs valued at 2004/2005 prices.

Main Results:

• Mean annual direct costs for depressed individuals (euro5241) were significantly higher than for non-depressed individuals (euro3648).
• Significant cost differences were observed in pharmaceuticals, medical supplies, dentures, and home care.
• A one-point increase in the GDS score correlated with a euro336 increase in annual direct costs, even after controlling for other factors.

Conclusions:

• Depression in old age substantially increases direct healthcare costs, independent of chronic medical conditions.
• The findings suggest that future demographic shifts in Germany will exacerbate the economic burden of elderly depression.
• Health policies should prioritize the development and implementation of cost-effective depression treatment strategies for the elderly.
