Abstract: Objective: To investigate and analyze the diagnosis and treatment status of atopic dermatitis in Gansu Province. Methods: An online survey questionnaire was distributed to dermatologists within the province, and data analysis was conducted using SPSS 29.0. Results: A total of 308 dermatologists participated in the survey. The most commonly used diagnostic criteria for adult/young adult AD were the Zhang criteria, while the Yao criteria were most frequently applied for infantile/childhood AD. 22.7% of the physicians considered AD to be the same disease as eczema. 20.8% of the doctors did not perform severity assessment before treatment. 24% of the respondents were unaware of the new types of drugs for AD treatment (PDE-4 inhibitors, biologics, and JAK inhibitors). In terms of drug availability, 56.8%, 47.4%, and 31.2% of the physicians reported that topical PDE-4 inhibitors, oral JAK inhibitors, and biologics, respectively, were not accessible in their regions. 19.2% of the doctors stated that none of the aforementioned new drugs were available in their areas. Regarding topical medication selection, calcineurin inhibitors (TCIs) were the most commonly used topical agents for mild-to-moderate AD in infants (40.6%) and in children/special sites (such as flexures and thin-skinned areas like the face and neck) (53.2%). For mild-to-moderate AD in young adults, adults, and the elderly, topical corticosteroids (TCS) were the most frequently used (56.2% and 54.9%, respectively). In systemic treatment, antihistamines were the most commonly used for mild-to-moderate AD (79.9%). For moderate-to-severe AD, corticosteroids were the most frequently used during acute phases (71.1%), while biologics were the most commonly used during non-acute phases (37.3%). Conclusion: The majority of dermatologists in our province comply with the domestic guidelines in the selection of diagnostic criteria for AD. However, there are issues such as difficulty in differentiating eczema from AD, lack of severity assessment before treatment, and poor accessibility and standardized use of new drugs.
