Popis: BACKGROUND/OBJECTIVES: We sought to quantify the reliability and validity of remote atopic dermatitis (AD) severity assessment using the Eczema Area and Severity Index (EASI) applied to caregiver-provided photos (p-EASI) and videos (v-EASI). METHODS: Children (0–17 years) with a physician diagnosis of AD were recruited. Caregivers took photos and a video of their child’s skin. A clinician scored in-person EASI on the same day, then p-EASI and v-EASI for each participant ten days or more between ratings. Two additional clinicians scored p-EASI and v-EASI. Lin’s concordance correlation coefficient (CCC) was employed to assess criterion validity using in-person EASI as the gold standard. Intraclass correlation coefficients (ICC) were calculated to assess interrater reliability of p-EASI and v-EASI. RESULTS: Fifty racially and ethnically diverse children (age (mean±SD): 4.3±4.4 years; 42% female) with a range of AD severity (EASI: 6.3±6.4) and Fitzpatrick Skin Types (1–2: 9%; 3–4: 60%; 5–6: 31%) were enrolled and received in-person EASI assessment. Fifty had p-EASI and 49 had v-EASI by the same in-person rater, and by two additional raters. The CCC and ICC for p-EASI were 0.89, 95% CI [0.83, 0.95]; and 0.81, 95% CI [0.71, 0.89], respectively. The CCC and ICC for v-EASI were 0.75, 95% CI [0.63, 0.88]; and 0.69, 95% CI [0.51, 0.81], respectively. CONCLUSIONS: In this diverse population with a range of skin tones, p-EASI showed good criterion validity and good interrater reliability. v-EASI showed moderate to good criterion validity and moderate interrater reliability. Both may be reliable and valid options for remote AD severity assessment.
