Abstract The impact of search strategies on systematic reviews (SR) of atopic dermatitis (AD) is unknown. The purpose of this review was to evaluate search strategies used in SR of AD and their impact on the frequency of manuscripts identified. MEDLINE and EMBASE were searched for SR related to AD. Simulations were performed by running combinations of search terms in MEDLINE and EMBASE. Overall, 250 SR met inclusion criteria, of which 225 specified search strategies. SR using 5–6 terms (20.0% to 12.1%) or ≥ 7 (40.0% to 18.8%) terms decreased, whereas SR using 3–4 terms numerically increased (18.8% to 30.2%) and 1–2 terms remained similar (37.5% to 38.9%) from 1999–2009 to 2015–2019. The most commonly searched terms were “atopic dermatitis” (n = 166), followed by “eczema” (n = 156), “dermatitis atopic’” (n = 81), “atopic eczema” (n = 74), “neurodermatitis” (n = 59), “Besniers prurigo” (n = 29), “infantile eczema” (n = 27), and “childhood eczema” (n = 19). Simulations revealed that “eczema” and “atopic dermatitis” yielded the most hits. The number of search terms that maximized hits in MEDLINE and EMBASE was 5 and 4, respectively. Search strategies for AD were heterogeneous, with high proportions of search strategies providing few search hits. Future studies should use standardized and optimized search terms.

Introduction Atopic dermatitis (AD) is a chronic inflammatory skin disease associated with heterogeneous symptoms (including itch, pain, sleep disturbance, psychosocial distress, anxiety, depression and cognitive dysfunction), triggers (including heat, sweat, climate and pollutants), lesional distribution (including flexural, extensor, hand and foot, head and neck), and associated signs (i
