Objectives: This study aimed to find out situation and treatments of psoriasis and economic burden for Psoriasis is a chronic disease, which is a intractable disease repeating improvement and deterioration and causing heavy economic burden to patients.
Methods: Data were collected by the survey through website with structured questionnaire. Frequencies, cross-tabulations, and multiple regression models were estimated. To find variables influencing the economic burden for treatment of psoriasis, hierarchial multiple regression models were estimated and explained based on the final model including confounding variables. Three models were estimated hierarchically to find the best model. present treatment of biological products, number of biological products, current severity, prescription period of the first biological product, average monthly household income, and male(dummy variables, Ref: female) were included in the first model. In the second model, we drooped present treatment of biological products, number of biological products, average monthly household income, and male and added the variables of present treatments as dummy variables(Ref: oriental medicine), In the third model, we added average monthly household income and male to the variables of the second model.
Results: Comparing with treatments of oriental medicine, patients treated with biological products perceived significantly less and patients treated with folk medicine perceived significantly higher economic burden. Current severity of psoriasis were estimated very significant negative coefficient on the perceived economic burden of treatment. Monthly household income was estimated as very significant positive coefficient. Prescription period of the first biological product, severity at the onset of psoriasis, and sex were estimated as insignificant coefficients.
Conclusion: Ways to reduce economic burden for treatment of psoriasis are needed, including decrease of out of pocket payment of treatments of psoriasis. Further studies are required to find whether higher income group and higher severity patients spend more cost in treating psoriasis or other confounding is present.
