Key clinical point: Air pollution due to a wildfire increased the rate of clinic visits for atopic dermatitis (AD), especially at a 0-week lag, in adults aged ≥65 years.
Major finding: In adults aged ≥65 years, the adjusted rate of clinic visits for AD during a week with a wildfire was 1.4 (95% CI 1.1-1.9) times the rate during weeks without wildfire and every 1-unit increase in the mean weekly smoke plume density score increased the rate of clinic visits for AD by 1.3 (95% CI 1.1-1.6) times.
Study details : This study analyzed the data of outpatient dermatology visits for AD (5529 visits) and itch (1319 visits).
Disclosures: This study did not report the source of funding. Dr. Grimes declared receiving grants from the University of California, San Francisco.
