ABSTRACT
BACKGROUND: Hidradenitis suppurativa (HS) is a chronic, painful disease affecting flexures and other skin regions, producing nodules, abscesses and skin tunnels. Laser treatment targeting hair follicles and deroofing of skin tunnels are standard HS interventions in some countries but are rarely offered in the UK. OBJECTIVES: To describe current UK HS management pathways and influencing factors to inform the design of future randomized controlled trials (RCTs). METHODS: THESEUS was a nonrandomized 12-month prospective cohort study set in 10 UK hospitals offering five interventions: oral doxycycline 200â mg daily; oral clindamycin and rifampicin both 300â mg twice daily for 10 weeks, extended for longer in some cases; laser treatment targeting hair follicles; deroofing; and conventional surgery. The primary outcome was the combination of clinician-assessed eligibility and participant hypothetical willingness to receive each intervention. The secondary outcomes were the proportion of participants selecting each intervention as their final treatment option; the proportion who switch treatments; treatment fidelity; and attrition rates. THESEUS was prospectively registered on the ISRCTN registry: ISRCTN69985145. RESULTS: The recruitment target of 150 participants was met after 18â months, in July 2021, with two pauses due to the COVID-19 pandemic. Baseline demographics reflected the HS secondary care population: average age 36â years, 81% female, 20% non-White, 64% current or ex-smokers, 86% body mass index ≥ 25, 68% with moderate disease, 19% with severe disease and 13% with mild disease. Laser was the intervention with the highest proportion (69%) of participants eligible and willing to receive treatment, then deroofing (58%), conventional surgery (54%), clindamycin and rifampicin (44%), and doxycycline (37%). Laser was ranked first choice by the greatest proportion of participants (41%). Attrition rates were 11% and 17% after 3 and 6â months, respectively. Concordance with doxycycline was 52% after 3â months due to lack of efficacy, participant choice and adverse effects. Delays with procedural interventions were common, with only 43% and 26% of participants starting laser and deroofing, respectively, after 3â months. Uptake of conventional surgery was too small to characterize the intervention. Switching treatment was uncommon and there were no serious adverse events. CONCLUSIONS: THESEUS has established laser treatment and deroofing for HS in the UK and demonstrated their popularity with patients and clinicians for future RCTs.

BACKGROUND: The Harmonising Outcome Measures for Eczema (HOME) initiative has agreed upon the Core Outcome Set (COS) for use in atopic dermatitis (AD) clinical trials, but additional guidance is needed to maximize its uptake. OBJECTIVES: To provide answers to some of the commonly asked questions about using the HOME COS; to provide data to help with the interpretation of trial results; and to support sample size calculations for future trials. METHODS AND RESULTS: We provide practical guidance on the use of the HOME COS for investigators planning clinical trials in patients with AD. It answers some of the common questions about using the HOME COS, how to access the outcome measurement instruments, what training/resources are needed to use them appropriately and clarifies when the COS is applicable. We also provide exemplar data to inform sample size calculations for eczema trials and encourage standardized data collection and reporting of the COS. CONCLUSIONS: By encouraging adoption of the COS and facilitating consistent reporting of outcome data, it is hoped that the results of eczema trials will be more comprehensive and readily combined in meta-analyses and that patient care will subsequently be improved.

Recap of atopic eczema (RECAP) is a self-reported 7-item questionnaire recommended by the Harmonising Outcome Measures in Eczema initiative to measure eczema control. As RECAP has not been validated in a real-world clinical population in Asia, RECAP was investigated as a measure of eczema control in Singapore. Patients with atopic eczema at the National Skin Centre from July 2019 to January 2020 were included for analysis. Both patient- and physician-reported outcome measures were available for correlation analyses. Correlation analysis was also performed to investigate construct validity, and floor or ceiling effects of RECAP. A total of 260 atopic eczema patients aged between 15 and 87 years were recruited. There were minimal floor and ceiling effects for RECAP scores. There were strong, significant correlations of RECAP with POEM (r = 0.84, p < 0.001) and DLQI (r = 0.81, p < 0.001). Correlation with SCORAD was moderate (r = 0.60, p < 0.001). Correlations remained similar after age, gender, and ethnicity adjustments. Discriminative validity was demonstrated by a significant linear trend of increasing RECAP scores with increasing eczema severity. RECAP demonstrates good discriminative and construct validity evidenced by strong correlations with symptoms and quality of life and moderate correlations with eczema signs. RECAP is useful to measure eczema control in Singapore.

BACKGROUND: Core outcome sets (COS) are consensus-driven sets of minimum outcomes that should be measured and reported in all clinical trials. COS aim to reduce heterogeneity in outcome measurement and reporting, and selective outcome reporting. Implementing COS into clinical trials is challenging. Guidance to improve COS uptake in dermatology is lacking. OBJECTIVES: To develop a structured practical guide to COS implementation. METHODS: Members of the Harmonising Outcome Measurement for Eczema (HOME) executive committee developed an expert opinion-based roadmap founded on a combination of a review of the COS implementation literature, the Core Outcome Measures in Effectiveness Trials (COMET) initiative resources, input from HOME members and experience in COS development and clinical trials. RESULTS: The data review and input from HOME members was synthesized into themes, which guided roadmap development: (a) barriers and facilitators to COS uptake based on stakeholder awareness/engagement and COS features; and (b) key implementation science principles (assessment-driven, data-centred, priority-based and context-sensitive). The HOME implementation roadmap follows three stages. Firstly, the COS uptake scope and goals need to be defined. Secondly, during COS development, preparation for future implementation is supported by establishing the COS as a credible evidence-informed consensus by applying robust COS development methodology, engaging multiple stakeholders, fostering sustained and global engagement, emphasizing COS ease of use and universal applicability, and providing recommendations on COS use. Thirdly, incorporating completed COS into primary (trials) and secondary (reviews) research is an iterative process starting with mapping COS uptake and stakeholders' attitudes, followed by designing and carrying out targeted implementation projects. Main themes for implementation projects identified at HOME are stakeholder awareness/engagement; universal applicability for different populations; and improving ease-of-use by reducing administrative and study burden. Formal implementation frameworks can be used to identify implementation barriers/facilitators and to design implementation strategies. The effect of these strategies on uptake should be evaluated and implementation plans adjusted accordingly. CONCLUSIONS: COS can improve the quality and applicability of research and, so, clinical practice but can only succeed if used and reported consistently. The HOME implementation roadmap is an extension of the original HOME roadmap for COS development and provides a pragmatic framework to develop COS implementation strategies.

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.

Core outcome sets are critically important outcomes that should be measured in clinical trials. Their absence in atopic dermatitis is a form of research waste and impedes combining evidence to inform patient care. Here, we articulate the rationale for core outcome sets in atopic dermatitis and review the work of the international Harmonising Outcome Measures for Eczema group from its inception in Munich, 2010. We describe core domain determination (what should be measured), to instrument selection (how domains should be measured), culminating in the complete core outcome measurement set in Tokyo, 2019. Using a "road map," Harmonising Outcome Measures for Eczema includes diverse research methods including Delphi and nominal group techniques informed by systematic reviews of properties of candidate instruments. The 4 domains and recommended instruments for including in all clinical trials of atopic dermatitis are patient symptoms, measured by Patient-Oriented Eczema Measure and peak Numerical Rating Scale 11 for itch intensity over 24 hours, clinical signs measured using the Eczema Area and Severity Index, quality of life measured by the Dermatology Life Quality Index series for adults, children, and infants, and long-term control measured by either Recap of atopic eczema or Atopic Dermatitis Control Tool.

BACKGROUND: Validated outcome measures are needed for vitiligo trials. OBJECTIVES: To assess construct validity, interpretability, reliability and acceptability of the Vitiligo Noticeability Scale (VNS). METHODS: We used images of vitiligo before and after treatment, plus outcome data, from the HI-Light Vitiligo trial. We compared outcome assessments made by trial participants with assessments of images by clinicians and people with vitiligo who were not trial participants [Patient and Public Involvement (PPI) panel]. Hypothesis testing assessed psychometric properties of the VNS, with κ statistics to assess agreement between outcomes. Three focus groups and two online discussion groups provided insight into the use of VNS by people with vitiligo. RESULTS: Our hypothesis of a positive association between VNS and participant-reported global treatment success was supported for trial participants (κ = 0·41 if VNS success was defined as ≥ 4; κ = 0·71 if VNS success was defined as ≥ 3), but not for the blinded PPI panel (κ = 0·28). As hypothesized, the association with participant-reported global success was higher for VNS (κ = 0·41) than for clinician-reported percentage repigmentation (κ = 0·17). Seventy-five per cent of trial participants valued a VNS of 3 (partial response) as a treatment success. Test-retest reliability was good: κ = 0·69 (95% confidence interval 0·63-0·74). Age and skin phototype did not influence interpretation of the VNS scores. To people with vitiligo, the VNS is an acceptable and meaningful patient-reported outcome measure. CONCLUSIONS: Trial participants may assess their vitiligo differently compared with blinded assessors. A VNS score of 3 may be more highly valued by people undergoing vitiligo treatment than was previously thought. What is already known about this topic? Vitiligo is a common condition, and can have a considerable psychological impact. A Vitiligo Core Outcome Set is being developed, to enable the results of vitiligo trials to be compared and combined more easily. The Vitiligo Noticeability Scale (VNS) is a patient-reported outcome measure (PROM) developed in partnership with people with vitiligo; initial validation studies have been promising. What does this study add? The VNS shows good construct validity, reliability and acceptability; it can be used in all ages and skin phototypes. All five levels of the VNS scale should be reported for transparency, to aid interpretation of trial findings, and to facilitate meta-analysis in systematic reviews. VNS assessments made by trial participants and independent observers are likely to be qualitatively different, making blinded assessment of VNS by independent observers difficult to interpret. Blinding of participants to trial interventions is recommended whenever possible. What are the clinical implications of the work? The VNS can be used as a PROM to assess the cosmetic acceptability of repigmentation at individual patches of vitiligo. A VNS score of 3 or more is likely to be valued by patients as a treatment success.

BACKGROUND: Recap of atopic eczema (RECAP) is a patient-reported outcome measure assessing eczema control. This instrument has been developed and validated in the UK. There are self-reported and proxy-reported versions in English, Dutch and German. However, it is unclear whether the self-reported version shows adequate content validity when completed by young people (8-16 years) in these languages. OBJECTIVES: To assess the content validity (comprehensibility, relevance and comprehensiveness) of the English, German and Dutch versions of the self-reported RECAP in young people with atopic eczema and to identify the most appropriate age cutoff for self-completion. METHODS: We conducted 23 semistructured cognitive interviews with young people aged 8-16 years, using the 'think-aloud' method. In Germany and the Netherlands, participants were recruited in dermatology clinics and in the UK through social media and existing mailing lists. Interviews were audio recorded, transcribed verbatim and analysed in the three languages, using a problem-focused coding manual. Transcripts were coded by two independent reviewers in each country. Themes were translated into English and compared across the three countries. RESULTS: Significant age-related comprehensibility issues with the last three items of the questionnaire occurred with young people aged 8-11 years, causing difficulties completing RECAP without help. However, older children had only minor problems and were able to complete the questionnaire by themselves. The self-reported version of RECAP has sufficient content validity for self-completion in young people aged 12 years and above. However, the German version with some translational adaptations may be appropriate for children from the age of 8 years. There may be some situations where the proxy version is needed for older children too. CONCLUSIONS: The self-reported version of RECAP is appropriate for use from the age of 12 years. The proxy version can be used in children younger than 12 years. Other measurement properties should be further investigated. What is already known about this topic? Recap of atopic eczema (RECAP) is an instrument recommended by the Harmonising Outcome Measures for Eczema initiative for the core outcome domain of long-term control of atopic eczema. Content validity of RECAP for self-completion by adults and of the proxy version has been assessed. What does this study add? In this study, content validity (comprehensibility, relevance and comprehensiveness) of the self-reported version of RECAP among young people (aged 8-16 years) with atopic eczema across the UK, Germany and the Netherlands is assessed. Based on these findings, key recommendations on how to measure eczema control in young people with atopic eczema are formulated. What are the clinical implications of this work? The Dutch, English and German self-completion versions of RECAP are recommended for use in adolescents from the age of 12 years. The proxy version could be used in children younger than 12 years or where children are cognitively or physically incapable of reporting their experience of eczema control. Caregivers should be encouraged to complete RECAP together with their child where possible.

BACKGROUND: Eczema is a common skin condition. Although topical corticosteroids have been a first-line treatment for eczema for decades, there are uncertainties over their optimal use. OBJECTIVES: To establish the effectiveness and safety of different ways of using topical corticosteroids for treating eczema. SEARCH METHODS: We searched databases to January 2021 (Cochrane Skin Specialised Register; CENTRAL; MEDLINE; Embase; GREAT) and five clinical trials registers. We checked bibliographies from included trials to identify further trials. SELECTION CRITERIA: Randomised controlled trials in adults and children with eczema that compared at least two strategies of topical corticosteroid use. We excluded placebo comparisons, other than for trials that evaluated proactive versus reactive treatment. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methods, with GRADE certainty of evidence for key findings. Primary outcomes were changes in clinician-reported signs and relevant local adverse events. Secondary outcomes were patient-reported symptoms and relevant systemic adverse events. For local adverse events, we prioritised abnormal skin thinning as a key area of concern for healthcare professionals and patients. MAIN RESULTS: We included 104 trials (8443 participants). Most trials were conducted in high-income countries (81/104), most likely in outpatient or other hospital settings. We judged only one trial to be low risk of bias across all domains. Fifty-five trials had high risk of bias in at least one domain, mostly due to lack of blinding or missing outcome data. Stronger-potency versus weaker-potency topical corticosteroids Sixty-three trials compared different potencies of topical corticosteroids: 12 moderate versus mild, 22 potent versus mild, 25 potent versus moderate, and 6 very potent versus potent. Trials were usually in children with moderate or severe eczema, where specified, lasting one to five weeks. The most reported outcome was Investigator Global Assessment (IGA) of clinician-reported signs of eczema. We pooled four trials that compared moderate- versus mild-potency topical corticosteroids (420 participants). Moderate-potency topical corticosteroids probably result in more participants achieving treatment success, defined as cleared or marked improvement on IGA (52% versus 34%; odds ratio (OR) 2.07, 95% confidence interval (CI) 1.41 to 3.04; moderate-certainty evidence). We pooled nine trials that compared potent versus mild-potency topical corticosteroids (392 participants). Potent topical corticosteroids probably result in a large increase in number achieving treatment success (70% versus 39%; OR 3.71, 95% CI 2.04 to 6.72; moderate-certainty evidence). We pooled 15 trials that compared potent versus moderate-potency topical corticosteroids (1053 participants). There was insufficient evidence of a benefit of potent topical corticosteroids compared to moderate topical corticosteroids (OR 1.33, 95% CI 0.93 to 1.89; moderate-certainty evidence). We pooled three trials that compared very potent versus potent topical corticosteroids (216 participants). The evidence is uncertain with a wide confidence interval (OR 0.53, 95% CI 0.13 to 2.09; low-certainty evidence). Twice daily or more versus once daily application We pooled 15 of 25 trials in this comparison (1821 participants, all reported IGA). The trials usually assessed adults and children with moderate or severe eczema, where specified, using potent topical corticosteroids, lasting two to six weeks. Applying potent topical corticosteroids only once a day probably does not decrease the number achieving treatment success compared to twice daily application (OR 0.97, 95% CI 0.68 to 1.38; 15 trials, 1821 participants; moderate-certainty evidence). Local adverse events Within the trials that tested 'treating eczema flare-up' strategies, we identified only 26 cases of abnormal skin thinning from 2266 participants (1% across 22 trials). Most cases were from the use of higher-potency topical corticosteroids (16 with very potent, 6 with potent, 2 with moderate and 2 with mild). We assessed this evidence as low certainty, except for very potent versus potent topical corticosteroids, which was very low-certainty evidence. Longer versus shorter-term duration of application for induction of remission No trials were identified. Twice weekly application (weekend, or 'proactive therapy') to prevent relapse (flare-ups) versus no topical corticosteroids/reactive application Nine trials assessed this comparison, generally lasting 16 to 20 weeks. We pooled seven trials that compared weekend (proactive) topical corticosteroids therapy versus no topical corticosteroids (1179 participants, children and adults with a range of eczema severities, though mainly moderate or severe). Weekend (proactive) therapy probably results in a large decrease in likelihood of a relapse from 58% to 25% (risk ratio (RR) 0.43, 95% CI 0.32 to 0.57; 7 trials, 1149 participants; moderate-certainty evidence). Local adverse events We did not identify any cases of abnormal skin thinning in seven trials that assessed skin thinning (1050 participants) at the end of treatment. We assessed this evidence as low certainty. Other comparisons Other comparisons included newer versus older preparations of topical corticosteroids (15 trials), cream versus ointment (7 trials), topical corticosteroids with wet wrap versus no wet wrap (6 trials), number of days per week applied (4 trials), different concentrations of the same topical corticosteroids (2 trials), time of day applied (2 trials), topical corticosteroids alternating with topical calcineurin inhibitors versus topical corticosteroids alone (1 trial), application to wet versus dry skin (1 trial) and application before versus after emollient (1 trial). No trials compared branded versus generic topical corticosteroids and time between application of emollient and topical corticosteroids. AUTHORS' CONCLUSIONS: Potent and moderate topical corticosteroids are probably more effective than mild topical corticosteroids, primarily in moderate or severe eczema; however, there is uncertain evidence to support any advantage of very potent over potent topical corticosteroids. Effectiveness is similar between once daily and twice daily (or more) frequent use of potent topical corticosteroids to treat eczema flare-ups, and topical corticosteroids weekend (proactive) therapy is probably better than no topical corticosteroids/reactive use to prevent eczema relapse (flare-ups). Adverse events were not well reported and came largely from low- or very low-certainty, short-term trials. In trials that reported abnormal skin thinning, frequency was low overall and increased with increasing potency. We found no trials on the optimum duration of treatment of a flare, branded versus generic topical corticosteroids, and time to leave between application of topical corticosteroids and emollient. There is a need for longer-term trials, in people with mild eczema.

When aiming to improve another person's long-term well-being, people may choose to induce a negative emotion in that person in the short term. We labeled this form of agent-target interpersonal emotion regulation altruistic affect worsening and hypothesized that it may happen when three conditions are met: (a) The agent experiences empathic concern for the target of the affect-worsening process, (b) the negative emotion to be induced helps the target achieve a goal (e.g., anger for confrontation or fear for avoidance), and (c) there is no benefit for the agent. This hypothesis was tested by manipulating perspective-taking instructions and the goal to be achieved while participants ( N = 140) played a computer-based video game. Participants following other-oriented perspective-taking instructions, compared with those following objective perspective-taking instructions, decided to induce more anger in a supposed fellow participant who was working to achieve a confrontation goal and to induce more fear in a supposed fellow participant who was working to achieve an avoidance goal.

Importance: Outcome measurement is an essential component of value-based health care and can aid patient care, quality improvement, and clinical effectiveness evidence generation. The Harmonising Outcome Measures for Eczema Clinical Practice initiative aims to identify a list of validated, feasible, outcome measurement instruments recommended to measure atopic dermatitis (AD) in the clinical practice setting. The clinical practice set is a list of instruments that clinicians can pick and choose from to suit their needs in the context of clinical care. Objective: To recommend instruments to measure clinical signs of AD in clinical practice. Evidence Review: Following the predefined roadmap, a mixed methods design was implemented and incorporated systematic reviews and qualitative consensus methods. Previous systematic reviews identified few clinical signs instruments with sufficient validation for recommendation. An updated systematic review evaluating the validity of clinical signs instruments informed an international meeting to reach consensus on recommended instruments to measure AD clinical signs in clinical practice. Consensus was defined as less than 30% disagreement. An in-person consensus exercise was held in Montreal, Canada, on October 16, 2022. The 34 attendees included patient and patient advocate research partners, health care professionals, researchers, methodologists, and industry representatives. Findings: The updated systematic review found that the Eczema Area and Severity Index (EASI), Scoring Atopic Dermatitis, and objective Scoring Atopic Dermatitis were the only instruments that demonstrated sufficient performance in all assessed measurement properties. The modified EASI and Signs Global Assessment × Body Surface Area instruments were also recommended. The EASI, Validated Investigator Global Assessment, and Investigator's Global Assessment multiplied by or measured concurrently with a body surface area measure achieved consensus in criteria and were adopted. Conclusions and Relevance: This consensus statement by the Harmonising Outcome Measures for Eczema initiative suggests that when assessing and documenting clinical signs of AD, there are several valid and feasible instruments that can best fit a clinician's specific practice needs. These instruments should improve and standardize the documentation of signs severity, help determine the effect of treatment, facilitate the generation of clinical effectiveness evidence, and enhance the implementation of value-based health care.

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.

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. TRIAL REGISTRATION: This trial was registered prospectively with the ISRCTN registry (ISRCTN79282252). URL www.EczemaCareOnline.org.uk .
ABSTRACT
OBJECTIVES: In psoriatic arthritis (PsA), self-management is important for patient function and quality of life. Behaviour change can be difficult, patients could benefit from high-quality support to initiate change. Our aim was to codesign the project as theory-informed, evidence-based, patient-focused, materials supporting healthy lifestyle changes for patients diagnosed with PsA. METHODS: Development of the materials was overseen by a steering group of patients with PsA, psychologists, rheumatologists, a design team and researchers. First, a literature review was performed to establish the evidence base for behaviours and potential interventions in PsA, including diet, weight, alcohol, smoking, exercise, anxiety, depression and stress. An initial roundtable of patients with PsA prioritised areas and content ideas. Draft materials including a website and downloadable materials were produced. A second roundtable of patients with PsA collected feedback on the draft content and design. A third roundtable was held with patients with PsA and a fourth with clinicians to refine the materials and ensuring that they were evidence based, accessible, interesting, and helpful to initiate and maintain change. A final evaluation survey was performed to review the draft website before launching the final materials. RESULTS: 15 candidate topics were prioritised. A website and set of postcards summarising the topics were developed by the design team and refined following feedback from the roundtable groups. CONCLUSION: This project created patient-focused resources to support behaviour change. It addresses common concerns of patients with PsA about how they may optimise their health by providing practical and brief interventions to challenge and support them to make changes.

Background: Hidradenitis suppurativa is a chronic inflammatory skin disease characterised by recurrent inflammatory lesions and skin tunnels in flexural sites such as the axilla. Deroofing of skin tunnels and laser treatment are standard hidradenitis suppurativa interventions in some countries but not yet introduced in the United Kingdom. Objective: To understand current hidradenitis suppurativa management pathways and what influences treatment choices to inform the design of future randomised controlled trials. Design: Prospective 12-month observational cohort study, including five treatment options, with nested qualitative interviews and an end-of-study consensus workshop. Setting: Ten United Kingdom hospitals with recruitment led by dermatology and plastic surgery departments. Participants: Adults with active hidradenitis suppurativa of any severity not adequately controlled by current treatment. Interventions: Oral doxycycline 200 mg once daily; oral clindamycin and rifampicin, both 300 mg twice daily for 10 weeks initially; laser treatment targeting the hair follicle (neodymium-doped yttrium aluminium garnet or alexandrite); deroofing; and conventional surgery. Main outcome measures: Primary outcome was the proportion of participants who are eligible, and hypothetically willing, to use the different treatment options. Secondary outcomes included proportion of participants choosing each of the study interventions, with reasons for their choices; proportion of participants who switched treatments; treatment fidelity; loss to follow-up rates over 12 months; and efficacy outcome estimates to inform outcome measure instrument responsiveness. Results: Between February 2020 and July 2021, 151 participants were recruited, with two pauses due to the COVID-19 pandemic. Follow-up rates were 89% and 83% after 3 and 6 months, decreasing to 70% and 44% at 9 and 12 months, respectively, because pandemic recruitment delays prevented all participants reaching their final review. Baseline demographics included an average age of 36 years, 81% female, 20% black, Asian or Caribbean, 64% current or ex-smokers and 86% with a raised body mass index. Some 69% had moderate disease, 19% severe disease and 13% mild disease. Regarding the study's primary outcome, laser treatment was the intervention with the highest proportion (69%) of participants who were eligible and hypothetically willing to receive treatment, followed by deroofing (58%), conventional surgery (54%), the combination of oral clindamycin and rifampicin (44%) and doxycycline (37%). Considering participant willingness in isolation, laser was ranked first choice by the greatest proportion (41%) of participants. The cohort study and qualitative study demonstrated that participant willingness to receive treatment was strongly influenced by their clinician. Fidelity to oral doxycycline was only 52% after 3 months due to lack of effectiveness, participant preference and adverse effects. Delays receiving procedural interventions were common, with only 43% and 26% of participants commencing laser therapy and deroofing, respectively, after 3 months. Treatment switching was uncommon and there were no serious adverse events. Daily pain score text messages were initiated in 110 participants. Daily responses reduced over time with greatest concordance during the first 14 days. Limitations: It was not possible to characterise conventional surgery due to a low number of participants. Conclusion: The Treatment of Hidradenitis Suppurativa Evaluation Study established deroofing and laser treatment for hidradenitis suppurativa in the United Kingdom and developed a network of 10 sites for subsequent hidradenitis suppurativa randomised controlled trials. Future work: The consensus workshop prioritised laser treatment and deroofing as interventions for future randomised controlled trials, in some cases combined with drug treatment. Trial registration: This trial is registered as ISRCTN69985145.
