Willingness to pay and quality of life in patients with atopic dermatitis

Atopic dermatitis (AD) is a frequent and burdensome disease. The objectives of this study were (1) to assess the willingness to pay (WTP) and quality of life (Qol) in AD patients and (2) to compare the results with data on other chronic skin diseases. To collect data, a non-interventional, cross-sectional nationwide postal survey on adult patients with clinically diagnosed AD was performed; socio-demographic data, clinical features/symptoms, WTP and QoL were recorded. WTP was assessed in three different approaches, including relative and absolute figures. Data from n = 384 AD patients (mean age 42.0, range 18-92, 69.8 % female) were analyzed. WTP for complete healing was on median a,not sign1,000 (average a,not sign11,884) and exceeded WTP in rosacea (median a,not sign500) but not in vitiligo (median a,not sign3,000). Mean Dermatology Life Quality Index (DLQI) was 8.5 (vitiligo 7.0; psoriasis 6.7; rosacea 4.3) and correlated with pruritus, xerosis and disturbed sleep. WTP and DLQI correlated only marginally (r (s) = 0.134, p = 0.01). In conclusion, AD patients show high WTP and markedly reduced QoL compared to other chronic skin diseases.
