Health related quality of life of rosacea patients in China assessed by DLQI and willingness to pay: Cross-Sectional Questionnaire Study
ABSTRACT
Background:
Rosacea is a chronic inflammatory dermatosis with facial skin involved, leading to physical and emotional problems, which greatly affected quality of life (QoL) of patients. Dermatology Life Quality Index (DLQI) and willingness to pay (WTP) are well-established instruments assessing the health-related quality of life (HRQoL), while very few studies have been focused on this topic about rosacea in China.
Objective:
To investigate HRQoL in Chinese rosacea patients assessed by DLQI and WTP and investigate potential predictors for patients with HRQoL severely affected.
Methods:
This cross-sectional study was conducted on 973 patients with rosacea. Sociodemographic data, clinical features and DLQI were collected, and WTP was assessed by three standardized items. Multivariable logistic analysis was performed to investigate independent factors influencing QoL.
Results:
921 questionnaires were accomplished by participants. The mean DLQI score was 11.6 (median 11). Patients were willing to pay an average of $1050.2 or € 896.2 (median $431.4 or € 368.1) for complete cure. 33.3% would like to pay more than 20% of their monthly income to achieve sustainable control. There were positive correlations between WTP with DLQI (P < .05). DLQI could be independently impacted by age (21-30 and 31-40, OR = 3.242 and 3.617, respectively), the occupational requirement of appearance (high, OR = 4.410), disease duration (< 2 years, OR = 1.582), oedema (OR = 1.844) and severity of flushing, burning, stinging and pruritus (severe, OR = 2.003, 1.981, 2.491, 2.249, respectively). There were no significant associations between WTP and most of the clinical factors.
Conclusions:
The QoL was negatively affected and should not be ignored among rosacea patients in China. Patients aged 21-40y, having occupational requirement of appearance, with the disease duration less than 2 years, and suffering severe flushing and related symptoms were more likely to have severe or very severe limitation of QoL.
