Tóm tắt	The SCORAD is a comprehensive clinician-administered tool for measuring the extent and severity of atopic dermatitis (eczema). Developed by the European Task Force on Atopic Dermatitis in 1993, it combines objective clinical assessment with subjective symptom reporting. It is the gold standard for atopic dermatitis severity in clinical trials and dermatology practice.	The POEM is a brief, patient-administered severity measure for atopic dermatitis that focuses on frequency of symptoms experienced over the past week. Developed by Charman, Venn, and Williams in 2004, it emphasizes the patient's lived experience rather than clinician observation, making it practical for routine clinical practice and remote monitoring. POEM is increasingly used alongside objective measures in clinical trials and outpatient care.	The Pruritus Visual Analog Scale (VAS) is a simple, single-item patient-administered tool measuring itch intensity on a continuous 0–10 (or 0–100) scale. Adapted from the original VAS for pain, it is one of the most frequently used outcome measures in dermatological research and clinical practice due to its simplicity, brevity, and responsiveness to treatment. Pruritus VAS is essential in trials of antipruritic therapies and in conditions where itching is a primary complaint (atopic dermatitis, psoriasis, pruritus ani, lichen planus).
