Supporting self-care for eczema: protocol for two randomised controlled trials of ECO (Eczema Care Online) interventions for young people and parents/carers

Online behavioural interventions for children and young people with eczema: a quantitative evaluation

BACKGROUND

Two online behavioural interventions (one website for parents/carers of children with eczema; and one for young people with eczema) have been shown in randomised controlled trials to facilitate a sustained improvement in eczema severity.

AIM

To describe intervention use and examine potential mediators of intervention outcomes and contextual factors that may influence intervention delivery and outcomes.

DESIGN AND SETTING

Quantitative process evaluation in UK primary care.

METHOD

Parents/carers and young people were recruited through primary care. Intervention use was recorded and summarised descriptively. Logistic regression explored sociodemographic and other factors associated with intervention engagement. Mediation analysis investigated whether patient enablement (ability to understand and cope with health issues), treatment use, and barriers to adherence were mediators of intervention effect. Subgroup analysis compared intervention effects among pre-specified participant subsets.

RESULTS

A total of 340 parents/carers and 337 young people were recruited. Most parents/carers (87%, n = 148/171) and young people (91%, n = 153/168) in the intervention group viewed the core introduction by 24 weeks. At 24 weeks, users had spent approximately 20 minutes on average on the interventions. Among parents/carers, greater intervention engagement was associated with higher education levels, uncertainty about carrying out treatments, and doubts about treatment efficacy at baseline. Among young people, higher intervention use was associated with higher baseline eczema severity. Patient enablement (the ability to understand and cope with health issues) accounted for approximately 30% of the intervention effect among parents/carers and 50% among young people.

CONCLUSION

This study demonstrated that positive intervention outcomes depended on a modest time commitment from users. This provides further support that the wider implementation of Eczema Care Online is justified.

Cost-effectiveness of two online interventions supporting self-care for eczema for parents/carers and young people

OBJECTIVE

To estimate the cost-effectiveness of online behavioral interventions (EczemaCareOnline.org.uk) designed to support eczema self-care management for parents/carers and young people from an NHS perspective.

METHODS

Two within-trial economic evaluations, using regression-based approaches, adjusting for baseline and pre-specified confounder variables, were undertaken alongside two independent, pragmatic, parallel group, unmasked randomized controlled trials, recruiting through primary care. Trial 1 recruited 340 parents/carers of children aged 0-12 years and Trial 2 337 young people aged 13-25 years with eczema scored ≥ 5 on Patient-Oriented Eczema Measure (POEM). Participants were randomized (1:1) to online intervention plus usual care or usual care alone. Resource use, collected via medical notes review, was valued using published unit costs in UK £Sterling 2021. Quality-of-life was elicited using proxy CHU-9D in Trial 1 and self-report EQ-5D-5L in Trial 2.

RESULTS

The intervention was dominant (cost saving and more effective) with a high probability of cost-effectiveness (> 68%) in most analyses. The exception was the complete case cost-utility analysis for Trial 1 (omitting participants with children aged < 2), with adjusted incremental cost savings of -£34.15 (95% CI  - 104.54 to 36.24) and incremental QALYs of - 0.003 (95% CI  - 0.021 to 0.015) producing an incremental cost per QALY of £12,466. In the secondary combined (Trials 1 and 2) cost-effectiveness analysis, the adjusted incremental cost was -£20.35 (95% CI  - 55.41 to 14.70) with incremental success (≥ 2-point change on POEM) of 10.3% (95% CI 2.3-18.1%).

CONCLUSION

The free at point of use online eczema self-management intervention was low cost to run and cost-effective.

Atopic eczema and the barriers to treatment adherence for children: a literature review

Atopic eczema is a chronic, non-contagious, relapsing inflammatory skin condition commonly seen in children and adults. Children with atopic eczema often endure complex skincare regimens that can keep the condition under control when managed effectively. Nonadherence, particularly to topical treatments, is one of the most common causes of treatment failure in atopic eczema. This literature review aimed to explore the barriers that influence treatment adherence in children and young people with atopic eczema and identify recommendations for practice. Six studies were included in the literature review and three themes were identified: relationships, medicines concerns and information deficits. Healthcare professionals should strive to develop trusting relationships with parents and understand the barriers to treatment adherence. Individualised conversations and education about medicines concerns, understanding the psychosocial effects of atopic eczema on children and families, and providing clear, consistent advice can be beneficial.

Comparison of lotions, creams, gels and ointments for the treatment of childhood eczema: the BEE RCT

Background

Emollients are recommended for children with eczema (atopic eczema/dermatitis). A lack of head-to-head comparisons of the effectiveness and acceptability of the different types of emollients has resulted in a 'trial and error' approach to prescribing.

Objective

To compare the effectiveness and acceptability of four commonly used types of emollients for the treatment of childhood eczema.

Design

Four group, parallel, individually randomised, superiority randomised clinical trials with a nested qualitative study, completed in 2021. A purposeful sample of parents/children was interviewed at ≈ 4 and ≈ 16 weeks.

Setting

Primary care (78 general practitioner surgeries) in England.

Participants

Children aged between 6 months and 12 years with eczema, of at least mild severity, and with no known sensitivity to the study emollients or their constituents.

Interventions

Study emollients sharing the same characteristics in the four types of lotion, cream, gel or ointment, alongside usual care, and allocated using a web-based randomisation system. Participants were unmasked and the researcher assessing the Eczema Area Severity Index scores was masked.

Main outcome measures

The primary outcome was Patient-Oriented Eczema Measure scores over 16 weeks. The secondary outcomes were Patient-Oriented Eczema Measure scores over 52 weeks, Eczema Area Severity Index score at 16 weeks, quality of life (Atopic Dermatitis Quality of Life, Child Health Utility-9 Dimensions and EuroQol-5 Dimensions, five-level version, scores), Dermatitis Family Impact and satisfaction levels at 16 weeks.

Results

A total of 550 children were randomised to receive lotion (analysed for primary outcome 131/allocated 137), cream (137/140), gel (130/135) or ointment (126/138). At baseline, 86.0% of participants were white and 46.4% were female. The median (interquartile range) age was 4 (2-8) years and the median Patient-Oriented Eczema Measure score was 9.3 (SD 5.5). There was no evidence of a difference in mean Patient-Oriented Eczema Measure scores over the first 16 weeks between emollient types (global p = 0.765): adjusted Patient-Oriented Eczema Measure pairwise differences - cream-lotion 0.42 (95% confidence interval -0.48 to 1.32), gel-lotion 0.17 (95% confidence interval -0.75 to 1.09), ointment-lotion -0.01 (95% confidence interval -0.93 to 0.91), gel-cream -0.25 (95% confidence interval -1.15 to 0.65), ointment-cream -0.43 (95% confidence interval -1.34 to 0.48) and ointment-gel -0.18 (95% confidence interval -1.11 to 0.75). There was no effect modification by parent expectation, age, disease severity or the application of UK diagnostic criteria, and no differences between groups in any of the secondary outcomes. Median weekly use of allocated emollient, non-allocated emollient and topical corticosteroids was similar across groups. Overall satisfaction was highest for lotions and gels. There was no difference in the number of adverse reactions and there were no significant adverse events. In the nested qualitative study (n = 44 parents, n = 25 children), opinions about the acceptability of creams and ointments varied most, yet problems with all types were reported. Effectiveness may be favoured over acceptability. Parents preferred pumps and bottles over tubs and reported improved knowledge about, and use of, emollients as a result of taking part in the trial.

Limitations

Parents and clinicians were unmasked to allocation. The findings may not apply to non-study emollients of the same type or to children from more ethnically diverse backgrounds.

Conclusions

The four emollient types were equally effective. Satisfaction with the same emollient types varies, with different parents/children favouring different ones. Users need to be able to choose from a range of emollient types to find one that suits them.

Future work

Future work could focus on how best to support shared decision-making of different emollient types and evaluations of other paraffin-based, non-paraffin and 'novel' emollients.

Evaluating the effect of weekly patient-reported symptom monitoring on trial outcomes: results of the Eczema Monitoring Online randomized controlled trial

BACKGROUND

Patient-reported outcome measures (PROMs) are commonly used in eczema clinical trials. Several trials have used PROMs weekly for symptom monitoring. However, the increased frequency of patient-reported symptom monitoring may prompt participants to enhance the self-management of eczema and increase standard topical treatment use that can lead to improvements in outcomes over time. This is concerning as weekly symptom monitoring may constitute an unplanned intervention, which may mask small treatment effects and make it difficult to identify changes in the eczema resulting from the treatment under investigation.

OBJECTIVES

To evaluate the effect of weekly patient-reported symptom monitoring on participants' outcomes and to inform the design of future eczema trials.

METHODS

This was an online parallel-group nonblinded randomized controlled trial. Parents/carers of children with eczema and young people and adults with eczema were recruited online, excluding people scoring < 3 points on the Patient Oriented Eczema Measure (POEM), to avoid floor effects. Electronic PROMs were used for data collection. Participants were allocated using online randomization (1 : 1) to weekly POEM for 7 weeks (intervention) or no POEM during this period (control). The primary outcome was change in eczema severity based on POEM scores, assessed at baseline and week 8. Secondary outcomes included change in standard topical treatment use and data completeness at follow-up. Analyses were conducted according to randomized groups in those with complete data at week 8.

RESULTS

A total of 296 participants were randomized from 14 September 2021 to 16 January 2022 (71% female, 77% white, mean age 26.7 years). The follow-up completion rate was 81.7% [n = 242; intervention group, n = 118/147 (80.3%); control group n = 124/149 (83.2%)]. After adjusting for baseline disease severity and age, eczema severity improved in the intervention group (mean difference in POEM score -1.64, 95% confidence interval -2.91 to -0.38; P = 0.01). No between-group differences were noted in the use of standard topical treatments and data completeness at follow-up.

CONCLUSIONS

Weekly patient-reported symptom monitoring led to a small perceived improvement in eczema severity.

Eczema Care Online behavioural interventions to support self-care for children and young people: two independent, pragmatic, randomised controlled trials

OBJECTIVE

To determine the effectiveness of two online behavioural interventions, one for parents and carers and one for young people, to support eczema self-management.

DESIGN

Two independent, pragmatic, parallel group, unmasked, randomised controlled trials.

SETTING

98 general practices in England.

PARTICIPANTS

Parents and carers of children (0-12 years) with eczema (trial 1) and young people (13-25 years) with eczema (trial 2), excluding people with inactive or very mild eczema (≤5 on POEM, the Patient-Oriented Eczema Measure).

INTERVENTIONS

Participants were randomised (1:1) using online software to receive usual eczema care or an online (www.EczemaCareOnline.org.uk) behavioural intervention for eczema plus usual care.

MAIN OUTCOME MEASURES

Primary outcome was eczema symptoms rated using POEM (range 0-28, with 28 being very severe) every four weeks over 24 weeks. Outcomes were reported by parents or carers for children and by self-report for young people. Secondary outcomes included POEM score every four weeks over 52 weeks, quality of life, eczema control, itch intensity (young people only), patient enablement, treatment use, perceived barriers to treatment use, and intervention use. Analyses were carried out separately for the two trials and according to intention-to-treat principles.

RESULTS

340 parents or carers of children (169 usual care; 171 intervention) and 337 young people (169 usual care; 168 intervention) were randomised. The mean baseline POEM score was 12.8 (standard deviation 5.3) for parents and carers and 15.2 (5.4) for young people. Three young people withdrew from follow-up but did not withdraw their data. All randomised participants were included in the analyses. At 24 weeks, follow-up rates were 91.5% (311/340) for parents or carers and 90.2% (304/337) for young people. After controlling for baseline eczema severity and confounders, compared with usual care groups over 24 weeks, eczema severity improved in the intervention groups: mean difference in POEM score -1.5 (95% confidence interval -2.5 to -0.6; P=0.002) for parents or carers and -1.9 (-3.0 to -0.8; P<0.001) for young people. The number needed to treat to achieve a 2.5 difference in POEM score at 24 weeks was 6 in both trials. Improvements were sustained to 52 weeks in both trials. Enablement showed a statistically significant difference favouring the intervention group in both trials: adjusted mean difference at 24 weeks -0.7 (95% confidence interval -1.0 to -0.4) for parents or carers and -0.9 (-1.3 to -0.6) for young people. No harms were identified in either group.

CONCLUSIONS

Two online interventions for self-management of eczema aimed at parents or carers of children with eczema and at young people with eczema provide a useful, sustained benefit in managing eczema severity in children and young people when offered in addition to usual eczema care.

'Eczema shouldn't control you; you should control eczema': qualitative process evaluation of online behavioural interventions to support young people and parents/carers of children with eczema

BACKGROUND

There is a lack of well-conducted randomized controlled trials evaluating the effectiveness of theory-based online interventions for eczema. To address these deficiencies, we previously developed and demonstrated the effectiveness of two online behavioural interventions: Eczema Care Online for parents/carers of children with eczema, and Eczema Care Online for young people with eczema.

OBJECTIVES

To explore the views and experiences of people who have used the Eczema Care Online interventions to provide insights into how the interventions worked and identify contextual factors that may impede users' engagement with the interventions.

METHODS

Qualitative semistructured interviews were conducted with 17 parents/carers of children with eczema and 17 young people with eczema. Participants were purposively sampled from two randomized controlled trials of the interventions and recruited from GP surgeries in England. Transcripts were analysed using inductive thematic analysis, and intervention modifications were identified using the person-based approach table of changes method.

RESULTS

Both young people and parents/carers found the interventions easy to use, relatable and trustworthy, and perceived that they helped them to manage their eczema, thus suggesting that Eczema Care Online may be acceptable to its target groups. Our analysis suggested that the interventions may reduce eczema severity by facilitating empowerment among its users, specifically through improved understanding of, and confidence in, eczema management, reduced treatment concerns, and improved treatment adherence and management of irritants/triggers. Reading about the experiences of others with eczema helped people to feel 'normal' and less alone. Some (mainly young people) expressed firmly held negative beliefs about topical corticosteroids, views that were not influenced by the intervention. Minor improvements to the design and navigation of the Eczema Care Online interventions and content changes were identified and made, ready for wider implementation.

CONCLUSIONS

People with eczema and their families can benefit from reliable information, specifically information on the best and safest ways to use their eczema treatments early in their eczema journey. Together, our findings from this study and the corresponding trials suggest wider implementation of Eczema Care Online (EczemaCareOnline.org.uk) is justified.

How we treat atopic dermatitis now and how that will change over the next 5 years

We live in exciting times in atopic dermatitis therapeutics, with many novel treatments in the clinical trial pipeline. Frustratingly, most of these trials are vehicle- or placebo-controlled, rather than head-to-head comparisons. Network meta-analyses can rank treatments against each other, even for placebo-controlled studies, aiding evidence-based guideline formulation and clinical decision-making. Treatment registries are an important additional vehicle to collect 'real-world' data on the long-term (cost) effectiveness and safety of the new drugs, outside of the stringent and short-term settings of clinical trials. As further agents enter clinical practice, the need for biomarkers of treatment response and drug safety becomes more pressing to move us towards personalized medicine and to avoid wasting healthcare resources. This review takes stock of our current treatment armamentarium for atopic dermatitis, highlights important gaps in our knowledge - including the relatively low number of studies conducted in children - and maps out how our treatment approaches for atopic dermatitis can become more targeted and holistic in the future.

Supporting families managing childhood eczema: developing and optimising eczema care online using qualitative research

BACKGROUND

Childhood eczema is often poorly controlled owing to underuse of emollients and topical corticosteroids (TCS). Parents/carers report practical and psychosocial barriers to managing their child's eczema, including child resistance. Online interventions could potentially support parents/carers; however, rigorous research developing such interventions has been limited.

AIM

To develop an online behavioural intervention to help parents/carers manage and co-manage their child's eczema.

DESIGN AND SETTING

Intervention development using a theory-, evidence-, and person-based approach (PBA) with qualitative research.

METHOD

A systematic review and qualitative synthesis of studies (n = 32) and interviews with parents/carers (n = 30) were used to identify barriers and facilitators to effective eczema management, and a prototype intervention was developed. Think-aloud interviews with parents/carers (n = 25) were then used to optimise the intervention to increase its acceptability and feasibility.

RESULTS

Qualitative research identified that parents/carers had concerns about using emollients and TCS, incomplete knowledge and skills around managing eczema, and reluctance to transitioning to co-managing eczema with their child. Think-aloud interviews highlighted that, while experienced parents/carers felt they knew how to manage eczema, some information about how to use treatments was still new. Techniques for addressing barriers included providing a rationale explaining how emollients and TCS work, demonstrating how to use treatments, and highlighting that the intervention provided new, up-to-date information.

CONCLUSION

Parents/carers need support in effectively managing and co-managing their child's eczema. The key output of this research is Eczema Care Online for Families, an online intervention for parents/carers of children with eczema, which is being evaluated in a randomised trial.

Eczema Care Online: development and qualitative optimisation of an online behavioural intervention to support self-management in young people with eczema

OBJECTIVES

To describe the development of Eczema Care Online (ECO), an online behaviour change intervention for young people with eczema (phase I); and explore and optimise the acceptability of ECO among this target group using think-aloud interviews (phase II).

METHODS

Theory-based, evidence-based and person-based approaches to intervention development were used. In phase I, a qualitative systematic review and qualitative interviews developed an in-depth understanding of the needs and challenges of young people with eczema. Guiding principles highlighted key intervention design objectives and features to address the needs of this target group to maximise user engagement. Behavioural analysis and logic modelling developed ECO's hypothesised programme theory. In phase II, qualitative think-aloud interviews were carried out with 28 young people with eczema and the intervention was optimised based on their feedback.

RESULTS

The final intervention aimed to reduce eczema severity by supporting treatment use (emollients, topical corticosteroids/topical calcineurin inhibitors), management of irritants/triggers, emotional management and reducing scratching. Generally, young people expressed positive views of intervention content and design in think-aloud interviews. Quotes and stories from other young people with eczema and ECO's focus on living with eczema (not just topical treatments) were valuable for normalising eczema. Young people believed ECO addressed knowledge gaps they had from childhood and the safety information about topical corticosteroids was reassuring. Negative feedback was used to modify ECO.

CONCLUSIONS

A prototype of the ECO intervention was developed using rigorous and complementary intervention development approaches. Subsequent think-aloud interviews helped optimise the intervention, demonstrated ECO is likely to be acceptable to this target group, and provided support for our guiding principles including key design objectives and features to consider when developing interventions for this population. A randomised controlled trial and process evaluation of the intervention is underway to assess effectiveness and explore user engagement with the intervention's behavioural goals.

How has the COVID-19 pandemic affected eczema self-management and help seeking? A qualitative interview study with young people and parents/carers of children with eczema

Background

Eczema can have a considerable impact on quality of life. Treatments can improve this, but management is complex. Barriers to eczema self‐management may be impacted upon by environmental context, such as the COVID‐19 pandemic.

Objectives

To explore experiences of eczema, self‐management, and accessing healthcare and advice during the COVID‐19 pandemic among young people with eczema and parents/carers of children with eczema.

Methods

Qualitative semi‐structured interviews were carried out with 36 participants recruited from general practices as part of randomised controlled trials of online eczema resources.

Results

Changes to everyday life—Periods of staying at home due to the pandemic alter the burden of eczema, with reports of an improved routine and application of topical treatments for many, but difficulties with handwashing for others. Parents/carers reported improved eczema control due to closures of educational settings. Young people reported higher stress that may have triggered eczema flare‐ups. Changes to access to advice and treatment—There was a reluctance to seek medical appointments in a non‐emergency situation. Participants reported a lack of trust in the outcome of telephone consultations because health professionals were unable to see or feel the skin. Delays or difficulties when obtaining appointments and treatments caused frustration. Access to an online eczema resource was reported to have extra value in the context of the pandemic.

Conclusion

Changes to lifestyle and access to healthcare during the pandemic have affected eczema and self‐management. Healthcare settings may want to consider providing extra reassurance around remote consultations.

Evidence-based management of eczema: five things that should be done more and five things that should be dropped

PURPOSE OF REVIEW

We provide readers with an evidence-informed opinion on current treatments for eczema (atopic dermatitis) with the intention of improving patient care. We suggest five treatment aspects that should be promoted and five that should be demoted. Evidence sources include key randomized controlled trials and systematic reviews.

RECENT FINDINGS

Under-treatment of eczema can be countered by more aggressive use of topical therapies including the 'get control then keep control' regimen, and systemics for severe disease, supplemented with good patient education. Topical corticosteroids should be used once daily rather than twice daily. Topical calcineurin inhibitors are useful for sensitive sites. There is little evidence to support the continued use of oral antihistamines, oral or topical antistaphylococcal treatments for infected eczema or probiotics for treating eczema. Nonpharmacological treatments including silk clothing, ion-exchange water softeners and emollient bath additives have not been shown to benefit eczema patients. Despite promising pilot studies, large trials suggest that emollients from birth do not prevent eczema and may result in harms such as increased skin infections and food allergy.

SUMMARY

New evidence-based insights on existing and newer treatments allow clinicians the opportunity to change their practice in a way that enhances patients' quality of life.
