(HealthDay News) — Psoriasis causes up to $135 billion a year in direct and indirect costs, according to research published online January 7 in JAMA Dermatology.

According to data included in the report, about 3.2% of the U.S. population has psoriasis. In the new analysis, a team led by Elizabeth Brezinski, MD, of the University of California Davis reviewed 22 studies to estimate the total annual cost of psoriasis to Americans.

The researchers calculated health care and other costs associated with the skin condition at between $112 billion and $135 billion in 2013. Direct costs of psoriasis ranged from $51.7 billion to $63.2 billion, and indirect costs – such as missed work days – ranged from $23.9 billion to $35.4 billion. Other health problems related to psoriasis cost more than $36.4 billion, and treating the physical and mental health effects of psoriasis cost up to $11,498 per patient.

“The direct health care costs are significantly greater for patients with psoriasis than for the general population and are also higher for patients with increasing psoriasis disease severity,” the authors write.
