Development of a Pediatric Dermatology Screening Tool Based on Two Parent-Reported Skin Symptoms: Comparison of Parental Recognition and Physician Diagnosis of Skin Symptoms of Infants and Toddlers

AIM: The objective of the present study was to develop a tool for mothers to assess their children’s skin condition with the ultimate goal of its wider use in general health checkups for infants and toddlers. METHODS: This was a single-institution, cross-sectional study in Japan, targeting parents of 200 infants and toddlers who visited a dermatology clinic between December 2018 and March 2019. The parents completed a self-administered survey of the mother’s perception of her child’s dermatological symptoms, itchiness, and sleep status, and a quality-oflife assessment, using a nine-question version of the Quality of life in Primary Caregivers of children with Atopic Dermatitis questionnaire (QP9). The attending physician was asked to complete a form about the child’s dermatological condition and the treatment prescribed. The severity of the dermatological condition noted by the physician was compared with the combined response to the 3 perception items (dermatological condition, itchiness, and sleep) reported by the parents, in order to identify the optimal cutoff score. RESULTS: Of 200 parent questionnaires distributed, 198 (99% response rate) were returned and analyzed, along with the responses from 198 physician records (100% response rate). The optimal cutoff score was 2/3 for the total score (range 0-6) for 2 items, itchiness and sleep status (sensitivity 73%, specificity 64%). There was a significant difference in QP9 scores between the 2 groups categorized by the cutoff score CONCLUSIONS: A pediatric dermatological screening tool based on 2 symptoms reported by the parents of children with atopic dermatitis was developed, and its precision and criterion-related validity were confirmed. This simple tool could help parents become better aware of their children’s skin condition and allow healthcare workers to provide adequate skin care advice. This practical tool could be widely applicable in primary child care and public health service settings.
