Regional Differences in Healthcare Resource Use for Psoriasis

States in the southern US have the greatest access to biologics and patients with psoriasis incurred fewer ambulatory and emergency visits, a new study found. The cross-sectional study used the 1996-2015 Medical Expenditure Panel Survey data to compare health care resource use and costs for patients with psoriasis among the 4 US census regions. Researchers found:

  • The greatest access for biologics was in the South, followed by Northeast, West, and Midwest.
  • Ambulatory visits per patient per year were highest in the West.
  • The proportion of patients with ≥1 emergency department (ED) visits was highest in the Northeast.
  • Compared with the remainder of the US, the West incurred the lowest total health care costs and lowest drug costs.
