Patient Education Programs in Pediatric Atopic Dermatitis: A Systematic Review of Randomized Controlled Trials and Meta-Analysis.

Introduction: Patient education is crucial for improving disease outcomes in atopic dermatitis (AD). This review aims to summarize evidence about the effectiveness of educational programs for parents of pediatric AD patients.

Methods: PubMed and Embase (inception to Feb 2020) were searched and randomized controlled trials (RCTs) in English were included. Risk of bias was assessed using Cochrane risk of bias tools and quality of evidence was assessed by Grading of Recommendations Assessment, Development and Evaluation (GRADE). Pooled standardized mean difference (SMD) and 95% confidence intervals (CIs) were calculated for the disease severity instrument (Scoring of Atopic Dermatitis, SCORAD) and quality of life (QoL) instruments using the random-effects model.

Results: A total of 13 RCTs were included in the systematic review. The meta-analysis of SCORAD contained seven studies with a total of 1853 patients. The reduction in disease severity (SCORAD) was larger in the treatment group (SMD = - 8.22, 95% CI = - 11.29, - 5.15; P < 0.001; I  =  78.6%). Subgroup analyses revealed that the association was modified by the frequency of sessions (P for Cochran Q  <  0.01) and the duration of follow-up (P for Cochran Q   <  0.01). No significant effect-modification was observed for disease severity and borderline significance was observed for session delivery (individual vs group session). The pooled effect sizes for QoL measures including Dermatitis Family Index (SMD = - 0.65, 95% CI = - 1.49, 0.18), Children's Dermatology Life Quality Index (SMD = - 1.61, 95% CI = - 3.76, 0.55; I= 89.0%) and Infants' Dermatology Quality of Life Index (SMD = 0.30, 95% CI = - 1.04, 1.63; I= 63.1%) were not significant.

Conclusions: Structured patient education is beneficial and should be implemented for the management of AD patients. However, an optimal delivery mode needs to be determined.
