Table 5 Costs in € per year and intangible costs (quality of life) measured by the Visual analog scale (VAS)

From: Financial burden and quality of life of informal caregivers of patients with wet age-related macular degeneration

Costs in € per year and intangible costs (QoL) measured by the Visual analog scale (VAS) Total sample
(n = 150)
Visual acuity
>0.3
(n = 92)
Visual acuity
≤0.3 - >0.1
(n = 26)
Visual auity
≤0.1
(n = 32)
Mean SD Mean SD Mean SD Mean SD
Total direct costs (€/year) 539 1,265 395 860 239 278 1,196 2,208
Direct medical costs (€/year) 133 336 90 217 62 138 314 588
Direct non medical costs (€/year) 405 1,104 305 848 176 254 881 1,780
Intangible costs (VAS) 6.7 1.9 6.8 2.0 7.2 1.7 6.2 1.7
QoL of caregivers living in the same household (n = 65) 6.6 2.0       
QoL of caregivers not living in the same household (n = 83) 6.9 1.8       
QoL of sons (n = 19) 6.7 2.2       
QoL of daughters (n = 40) 6.9 1.9       
QoL of female spouses (n = 41) 6.3 1.8       
QoL of male spouses (n = 29) 6.6 1.7       
  1. The values are divided in the total sample and the three different visual acuities. It becomes clear that total direct costs, direct medical and direct non-medical cost increase with a lower visual acuity apart from the visual acuity >0.3 to the visual acuity ≤0.3 - >0.1. Concerning the intangible costs of the different caregivers, it gets clear, that there is no significant strain difference
