Topical treatment use and under-use in childhood eczema: secondary analysis of RCTs and cohort data in the UK and the Netherlands

Abstract

Background: underuse of emollients and topical corticosteroids (TCS) contributes to uncontrolled atopic eczema, but variations between countries remain unclear.

Aim: to compare the actual use of emollient and TCS use in childhood eczema in the UK and The Netherlands (NL) and examine treatment adherence in relation to guidelines.

Design & setting: a secondary analysis of data from the Rotterdam Eczema cohort study (n=367) (NL), the BATHE trial (n=482) (UK) and BEE trial (n=520) (UK).Methods: Frequency of emollient and TCS use were compared at baseline and after 12-16 weeks of follow-up by age, sex and disease severity. Treatment adherence was defined as: 1 a) not using an emollient at all, 1b) not using an emollient when a TCS was used, 2) not using a TCS when eczema is mild or worse. Overall undertreatment was defined as category 1 and 2 combined.

Results: in total, questionnaire data from 1312 children (aged 3 months-17 years) with mostly mild (26-37%) or moderate (45-48%) eczema were analysed. Not using an emollient was significantly more prevalent in NL at baseline (14%) and follow-up (19%) than in the UK (4% and 7.6%, respectively). Not using a TCS when eczema is mild or worse differed significantly (P<0.05) between countries. The overall undertreatment rate was high and did not differ significantly between countries at baseline (UK 52.0%-NL 48.2%) and follow-up (UK 45.0%-NL 49.8%).

Conclusion: undertreatment with emollients and TCS are common and a reminder for clinicians to explain treatment rationale and check treatment adherence. Differences in treatment practices between countries warrant further exploration.
