Aims: Atopic dermatitis (AD) is a chronic skin disease that creates a significant burden to patients and society. There is scarcity in local data about the burden of AD in the Kingdom of Saudi Arabia (KSA). We aimed to fill in this gap and quantify the humanistic and economic burden of AD among adults and adolescents in KSA. Materials and methods: A literature search and local expert interviews were conducted to assess the disease burden. Prevalence values were estimated through the literature. International data about health-related quality of life lost owing to AD was adjusted to age and prevalence in KSA. Direct and indirect costs were calculated using a bottom-up approach. Resource utilization data were collected from local dermatologists through online interviews, and indirect costs were based on absenteeism and presenteeism estimates. Validation meetings were conducted with local experts to adjust the final estimates. Results: The age-standardized health loss per patient due to AD is 0.187 quality-adjusted life-years (QALYs) annually, aggregating to 64 thousand lost QALYs in KSA. The annual average direct cost for a patient with AD was 2924 Saudi Riyal (SAR; 780 USD), totaling 373 million SAR in KSA (99.5 million USD). This value represents 0.2% of the annual health expenditure in KSA. The total productivity loss due to AD was 1.36 billion SAR (363.7 million USD). Overall, the economic burden of AD consumes up to 0.059% of the national gross domestic product. Limitations: Local quality of life and productivity lost data were not available for KSA, so global averages were used, assuming these numbers also apply to KSA. Conclusion: Indirect costs represent a large proportion of AD burden in KSA. The disease has a substantial effect on patient quality of life and social well-being. Alleviating the burden might result in significant savings in resources to society.
