Economic Impact of Atopic Dermatitis in Korean Patients.

BACKGROUND

Atopic dermatitis is a global public health concern owing to its increasing prevalence and socioeconomic burden. However, few studies have assessed the economic impact of atopic dermatitis in Korea.

OBJECTIVE

We conducted a cost analysis of atopic dermatitis and evaluated its economic impacts on individual annual disease burden, quality of life, and changes in medical expenses with respect to changes in health related-quality of life.

METHODS

The cost analysis of atopic dermatitis was performed by reviewing the home accounting records of 32 patients. The economic impact of the disease was evaluated by analyzing questionnaires. To handle uncertainties, we compared the results with the data released by the Health Insurance Review & Assessment Board on medical costs claimed by healthcare facilities.

RESULTS

The direct cost of atopic dermatitis per patient during the 3-month study period was 541,280 Korean won (KRW), and expenditures on other atopic dermatitis-related products were 120,313 KRW. The extrapolated annual direct cost (including expenditures on other atopic dermatitis-related products) per patient was 2,646,372 KRW. The estimated annual indirect cost was 1,507,068 KRW. Thus, the annual cost of illness of atopic dermatitis (i.e., direct+indirect costs) was estimated to be 4,153,440 KRW.

CONCLUSION

The annual total social cost of atopic dermatitis on a national level is estimated to be 5.8 trillion KRW.
