A Randomized Controlled Trial of an Eczema Care Plan. OBJECTIVE: To test whether an eczema care plan (ECP) would improve provider documentation and management, decrease eczema severity, and increase patient quality of life (QOL) in the pediatric primary care setting. METHODS: We conducted a randomized controlled trial from June 2015 to September 2016 at a large hospital-based pediatric primary care clinic. Participants included children from 1 month to 16 years of age with a diagnosis of eczema. The intervention group received the ECP and the control group received usual care. Both groups completed a validated eczema severity scale (Patient-Oriented Eczema Measure [POEM]) and a QOL scale (Infant's Dermatitis Quality of Life Index [IDQOL]) or Children's Dermatology Life Quality Index [CDLQI]) before the visit and again ~1 month later. RESULTS: A total of 211 caregivers completed both the pre- and postintervention surveys (100 control group and 111 intervention group [94% completion]). Intervention group providers were more likely to recommend a comprehensive "step-up" plan (88%) vs 28%; P < .001, bleach baths (45%) vs 9%; P < .001, and wet wraps (50%) vs 7%; P < .001. They were also more likely to document providing a written plan to families (80%) vs 2%; P < .001. In the intervention and control groups, eczema severity and QOL improved between the pre- and postintervention periods. However, there was not a significant difference between the groups on either measure: POEM difference -0.8, 95% confidence interval (CI) -3.2 to 1.7; IDQOL difference -0.1, 95% CI -1.8 to 1.6; CDLQI difference 0.8, 95% CI -0.9 to 2.6. CONCLUSIONS: Intervention group providers documented more comprehensive eczema care than control group providers. Although patients improved on all measures in the postintervention period, the ECP did not augment that improvement.
