Objective To analyze the current clinic application of severe acne treatment, and to provide evidences to improve its treatment. Methods Using sampling survey, a total of 3 012 severe acne patients who visited the dermato-logical department of 35 hospitals over the country for the first time were selected for this study. Each patient filled a ques-tionnaire about their acknowledgement, history of medical intervention and drug therapy of severe acne. Results Among all 3 012 patients with severe acne, 76.6%believed acne is a kind of skin disease, but only 35.2%of the patients went to see doctors at early stage of disease, while others choose interventions such as self-extrudation , topical medication or skin care products, herbal tea/folk recipes, beauty salons and application of coverture cosmetics. Among all severe acne patients, 2 388 cases (79.3%)had taken oral medications, which included 1 161(48.6%) patients who took anti-biotics. 394 cases (33.9%) took roxithromycine and 173 cases(14.9%) took other kinds of anti-biotics. 55.5%of all these patients who took oral medication less than 4 weeks in duration. 2 081 cases (69.1%) applied external drugs, in which includes 90 cases (4.3%) of using glucocorticoid, and 437 cases (21.0%) of using other kinds of external products. The adverse effects of topical treat-ments were commonly observed, such as erythema (512 cases, 24.6%), desquamation (683 cases, 32.8%), scab (73 cases, 3.5%) and hypersensitive (281 cases, 13.5%). Conclusion Severe acne is a disease need systematic treatment. but only mi-nority of the patients went to see doctors at early stage of disease. The current problems in treatment of severe acne include lack of target in choosing drugs, not long enough treatment course, and adverse effects of cutaneous administration.Early , safe and targeted medical attention with sufficient treatment course is encouraged.
