Atopic dermatitis (eczema) affects 15 to 20% of preschool children in western countries. In this study, 3 questions in a parental questionnaire were sufficient for diagnosing eczema in children: "rash? itchy? which areas?"
The 3 key questions were:
1. Does your child have a red rash/eczema which can come and go?
2. Has the rash caused itching or scratching?
3. Has this red rash/eczema affected any of the following areas (during the last week): Around the eyes, ears, scalp, cheeks, forehead, neck, trunk, folds of the elbows/behind the knees, wrist or ankle, outer arms/legs?
“Yes” answer to all 3 questions diagnosed eczema with sensitivity of 0.91 and a specificity of 1.
