Abstract

PURPOSE
Many different scoring systems have been proposed for assessing the severity of atopic dermatitis. The SCORAD (SCORing Atopic Dermatitis) is one of the best validated systems, but is too complicated and time-consuming for routine clinical use. The aim of this study is to evaluate the Three Item Severity (TIS) score in routine clinical practice and to investigate the correlation with SCORAD and quality of life. METHODS: The study was done on 69 cases of atopic dermatitis randomly selected by SCORAD severity in Kangdong Sacred Heart Hospital pediatric allergy clinic from March 2003 to August 2003. Patients were from three months old to 15 years old. A trained pediatrician assessed the TIS score and simultaneous 10 item questionnaire about quality of life (QOL) was checked. RESULTS: According to the SCORAD, there were 21 (30.4%) mild cases, 26 (37.7%) moderate cases and 22 (31.9%) severe cases out of total 69 patients. According to the TIS score, 21 (30.4%) cases were 0-2 point, 16 (23.2%) were 3 point, 11 (16.0%) were 4-5 point and include 21 (30.3%) were 6-9 point. In QOL score, 21-30 points were most common (36.2%). There was significant positive correlation between TIS score and SCORAD (Spearman's rs= 0.86, P< 0.01). There was significant positive correlation between TIS score and QOL (Spearman's rs=0.89, P< 0.01). CONCLUSION: The TIS score is a reliable and simple scoring system for atopic dermatitis. It is particularly suitable in general practice, for routine clinical use.
