An educational programme for patients with psoriasis and atopic dermatitis: a prospective randomized controlled trial

A systematic review of 454 randomized controlled trials using the Dermatology Life Quality Index: experience in 69 diseases and 43 countries

BACKGROUND

Over 29 years of clinical application, the Dermatology Life Quality Index (DLQI) has remained the most used patient-reported outcome (PRO) in dermatology due to its robustness, simplicity and ease of use.

OBJECTIVES

To generate further evidence of the DLQI's utility in randomized controlled trials (RCTs) and to cover all diseases and interventions.

METHODS

The methodology followed PRISMA guidelines and included seven bibliographical databases, searching articles published from 1 January 1994 until 16 November 2021. Articles were reviewed independently by two assessors, and an adjudicator resolved any opinion differences.

RESULTS

Of 3220 screened publications, 454 articles meeting the eligibility criteria for inclusion, describing research on 198 190 patients, were analysed. DLQI scores were primary endpoints in 24 (5.3%) of studies. Most studies were of psoriasis (54.1%), although 69 different diseases were studied. Most study drugs were systemic (85.1%), with biologics comprising 55.9% of all pharmacological interventions. Topical treatments comprised 17.0% of total pharmacological interventions. Nonpharmacological interventions, mainly laser therapy and ultraviolet radiation treatment, comprised 12.2% of the total number of interventions. The majority of studies (63.7%) were multicentric, with trials conducted in at least 42 different countries; 40.2% were conducted in multiple countries. The minimal clinically importance difference (MCID) was reported in the analysis of 15.0% of studies, but only 1.3% considered full score meaning banding of the DLQI. Forty-seven (10.4%) of the studies investigated statistical correlation of the DLQI with clinical severity assessment or other PRO/quality of life tools; and 61-86% of studies had within-group scores differences greater than the MCID in 'active treatment arms'. The Jadad risk-of-bias scale showed that bias was generally low, as 91.8% of the studies had Jadad scores of ≥ 3; only 0.4% of studies showed a high risk of bias from randomization. Thirteen per cent had a high risk of bias from blinding and 10.1% had a high risk of bias from unknown outcomes of all participants in the studies. In 18.5% of the studies the authors declared that they followed an intention-to-treat protocol; imputation for missing DLQI data was used in 34.4% of studies.

CONCLUSIONS

This systematic review provides a wealth of evidence of the use of the DLQI in clinical trials to inform researchers' and -clinicians' decisions for its further use. Recommendations are also made for improving the reporting of data from future RCTs using the DLQI.

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 Dermatitis Disease Education

There has been an influx of new educational resources for atopic dermatitis (AD) patients in recent years. The two primary organizations in the United States offering educational materials, online resources, and other forms of support include the National Eczema Association (NEA) and the American Academy of Dermatology (AAD). Educational workshops and interventions have emerged as tools that can deliver comprehensive information on AD, such as symptoms, treatments, and disease management. In regard to these workshops, studies have proven longer interventions to be more effective. Studies have also found multidisciplinary teams, including psychologists, dietitians, and AD specialists, to be more effective in AD treatment and education. Additionally, video-based education was found to be the most effective delivery medium compared to various written modes of education. Given the psychosocial impacts of AD, support groups have been found to improve life quality and decrease disease severity, with age-specific groups offering the greatest benefits. Technology such as social media and smartphones has also improved education. Social media has allowed the rapid exchange of information to wider audiences, but due to its unregulated nature, false information has also been disseminated. Despite this, web-based interventions have still been found to be satisfying, convenient, and effective in increasing treatment awareness. The advent of smartphone applications has provided patients with access to information on AD symptoms and treatment on demand. While the effectiveness of these promising applications hasn't been confirmed by studies, patient provider interactions via smartphone (teledermatology) have been found to be as effective as in-person appointments. This chapter will discuss these different types of emerging resources available to AD patients including educational materials, interventions, support groups, organizational support, and technological resources and their effectiveness.

Patient education in atopic dermatitis: a scoping review

BACKGROUND

Atopic dermatitis (AD) is a chronic inflammatory skin disease that affects children and adults. Poor treatment adherence in AD requires interventions to promote self-management; patient education in chronic diseases is key to self-management. Many international AD management guidelines published to date include a recommendation for educating patients as part of their treatment but there are no formal recommendations on how to deliver this knowledge. MAIN: We performed a scoping review to map the existing literature on patient education practices in AD and to highlight the clinical need for improved patient education in AD. The literature search was performed with the online databases MEDLINE, Embase, Grey Matters, ClinicalTrails.gov and the International Clinical Trials Registry Platform (ICTRP). The search strategy yielded 388 articles. Of the 388 articles screened, 16 studies met the eligibility criteria, and the quantitative data was summarized by narrative synthesis. The majority of studies were randomized controlled trials conducted in Europe, Asia and North America. Since 2002, there have been limited studies evaluating patient education in the treatment of AD. Frequent education methods used included group-based educational programs, educational pamphlets, individual consultations and online resources. Education was most commonly directed at caregivers and their children. Only one study compared the efficacy of different education methods. In all included studies, the heterogenous nature of outcome measures and study design limited the consistency of results. Despite the heterogeneity of studies, patient education was shown to improve quality of life (QoL), disease severity and psychological outcomes in AD patients.

CONCLUSION

This scoping review highlights that patient education is effective in a variety of domains relevant to AD treatment. Further comparative studies and randomized trials with longer-term follow-up are needed to provide validated and consistent patient education recommendations for AD; these may depend on age and population.

Patient Education with New Media Integration Self-Management Support Model Improves Therapeutic Outcomes of Rosacea Patients

Objective

To retrospectively analyze the factors influencing the treatment of rosacea patients with regular follow-up by self-management support in the new media chronic disease management model, to explore the effect of self-management support and to provide an objective basis for clinical application.

Methods

Female patients with rosacea who were regularly followed up for more than 6 months at the rosacea follow-up clinic of the Department of Dermatology, West China Hospital, Sichuan University, from March 2022 to June 2023, with erythema and capillary dilation as the main clinical phenotype, met the rosacea diagnostic criteria of the American Rosacea Expert Committee 2017 edition, and received medications recommended by the Chinese Rosacea Treatment Guidelines (2021 edition). A total of 125 patients were treated with combined photobiomodulation therapy (PBMT), and the patients were divided into a standardized group (CEA<1, IGA<1) and a non-standardized group (CEA≥1, IGA≥1) based on significant rosacea efficacy (CEA<1, IGA<1) within 6 months. The age, gender, education level, duration of rosacea, treatment regimen, education intensity, CEA, and IGA baseline data were compared between the two groups, and logistic regression analysis was performed to analyze the factors influencing the significant efficacy of rosacea.

Results

There was a significant difference in the mean length of education between the two groups (P<0.05), and the differences between the rest of the baseline information of the two groups were not statistically significant (P>0.05). Logistic regression analysis showed that the variable that significantly influenced the efficacy of treatment was the mean length of education (≥130.5 min/month), and the intensity of education was significantly associated with the efficacy of treatment.

Conclusion

Self-management support in the new media chronic disease management model has a positive impact on the treatment of rosacea patients.

Implementation of the Hand Hygiene Eczema Education Program to Improve Patient Knowledge and Symptoms

Background: COVID-19 hand hygiene recommendation had resulted in a hand eczema -exacerbation. The guidelines of care for the management of hand eczema recommend the use of educational interventions for patients. Objective: An educational intervention was designed to increase the patient's knowledge of appropriate hand hygiene and improve the patient's symptoms. Methods: The validated self-assessment patient-oriented eczema measure tool and pre- and post-tests were used to measure outcomes prior to educational intervention and again in 1-2 months postintervention. Of the 26 participants enrolled, 21 completed the study. The study included newly diagnosed or established patients with eczema, and the education material was available for all patients. Results: The difference between the average pretest and initial posttest was statistically significant (df = 20, P (T ≤ t) = 0.000663535, p < .05). Similarly, the difference between the average pretest and follow-up posttest was also statistically significant (df = 20, P (T ≤ t) < 0.001, p < .05). Participants also had a 2.04 mean point decrease in symptoms severity. Conclusions: The results demonstrated an improvement in patient's knowledge and reduction in symptoms. Implications for Nursing: The program can serve as a new guideline for managing hand eczema symptoms due to COVID-19 in the adult population in the private office setting.

The Effect of Lifestyle Changes on Disease Severity and Quality of Life in Patients with Plaque Psoriasis: A Narrative Review

Objective

To evaluate the effect of lifestyle changes on the severity of psoriasis and the quality of life in patients with psoriasis.

Methods

For this narrative review, PubMed, Embase and ClinicalTrials.gov were searched for lifestyle intervention studies with an intervention duration of at least 12 weeks.

Results

Thirty-four intervention studies were included. Most studies performed interventions in the diet of patients with psoriasis (n=9), or added supplements to the diet (n=18). Three studies comprised relaxation techniques and four studies combined relaxation or stress-reducing techniques with an educational program or exercise. No interventional studies were carried out regarding smoking, alcohol and sleep. Especially dietary and relaxation interventions showed promising results with respect to psoriasis severity and dermatology-related QoL, respectively. Regarding dietary supplements, the three largest studies investigating fish oil or vitamin D did not show significant effects.

Conclusion

There is some evidence that dietary and relaxation interventions could be promising with respect to psoriasis severity and dermatology-related QoL, respectively. Furthermore, our review identified important gaps in psoriasis lifestyle research regarding study design and reporting of outcomes.

Impact of an eHealth Smartphone App on the Mental Health of Patients With Psoriasis: Prospective Randomized Controlled Intervention Study

Background

Psoriasis has a negative impact on patients’ physical and mental health and can lead to anxiety and depression. Disease management strategies, including educational programs and eHealth devices, have been shown to improve health care for several chronic diseases. However, such disease management strategies are lacking in the routine care of patients with psoriasis.

Objective

This study aims to study the impact of a novel intervention that combines an educational program with a disease management smartphone app on the mental health of patients with psoriasis.

Methods

Patients with psoriasis in the intervention group received an educational program; attended visits on weeks 0, 12, 24, 36, and 60; and had access to the study app. Patients in the control group only attended the visits. The primary endpoint was a significant reduction of scores on the Hospital Anxiety and Depression Scale (HADS). Secondary end points were reductions in Dermatology Life Quality Index score, Psoriasis Area and Severity Index score, pruritus, and pain, as well as improvements in mood and daily activities. In addition, modulating effects of sex, age, disease duration, and app use frequency were evaluated.

Results

A total of 107 patients were included in the study and randomized into the control group (53/107, 49.5%) or intervention group (54/107, 50.5%). Approximately 71.9% (77/107) of the patients completed the study. A significant reduction in HADS-Depression (HADS-D) in the intervention group was found at weeks 12 (P=.04) and 24 (P=.005) but not at weeks 36 (P=.12) and 60 (P=.32). Patient stratification according to app use frequency showed a significant improvement in HADS-D score at weeks 36 (P=.004) and 60 (P=.04) and in HADS-Anxiety (HADS-A) score at weeks 36 (P=.04) and 60 (P=.05) in the group using the app less than once every 5 weeks. However, in patients using the app more than once every 5 weeks, no significant reduction in HADS-D (P=.84) or HADS-A (P=.20) score was observed over the 60-week study period compared with that observed in patients in the control group. All findings were independent of sex, age, and disease duration.

Conclusions

These findings support the use of a disease management smartphone app as a valid tool to achieve long-term improvement in the mental health of patients with psoriasis if it is not used too frequently. Further studies are needed to analyze the newly observed influence of app use frequency.

Impact of pharmacist care in the management of autoimmune disorders: A systematic review of randomized control trials and non-randomized studies

INTRODUCTION

Autoimmune disorders are chronic, self-mediated, misdirected immune responses against their own immune system. It required intensive, complex and costly drug treatment regimen increased the risk of pharmacotherapy error and adversely affects patients. Hence, pharmacist care will have vital roles in autoimmune disorders to achieve health related outcomes.

OBJECTIVES

This review aimed to gather evidence on the impact of pharmacist care on clinical, humanistic and economic outcomes, adherence to medications, and drug related problems in the management of autoimmune disorders among the usual care group.

METHODOLOGY

A comprehensive review conducted in compliance with the PRISMA statement and systematic search was performed across five databases included PubMed Central, Web of Sciences, Scopus, Cochrane Library andgoogle scholar from inception until August 2020. This research included full-text articles of randomized and non-randomized studies that evaluated impact of pharmacist care in autoimmune disorders.

RESULTS

A total of nine studies were included (seven RCTs and two non-RCTs), including 829 patients with autoimmune disorders. A total of four studies (80%) show an enhancement in at least one clinical parameter due to pharmacist care. A substantial improvement in at least one humanistic parameter observed in all five studies (100%). While four out of five studies (80%) clearly displayed a remarkable improvement in medication adherence in the pharmacist care group from baseline to the completion of follow-ups. One study quantified a 99.08% resolution of DRPs in the pharmacist care group. Another study estimated the cost of medical resources uses per patient and found no difference in cost-effectiveness over six months between groups.

CONCLUSION

This review reinforces the vital contribution of pharmacists to achieve clinical outcomes, humanistic outcomes, adherence to medications and DRPs in the efficient management of autoimmune disorders. However, no notable changes in economic outcomes were observed in this review.

Methods to improve quality of life, beyond medicines. Position statement of the European Academy of Dermatology and Venereology Task Force on Quality of Life and Patient Oriented Outcomes

The pharmaceutical approach to skin disease has been hugely successful, but despite effective drugs being available and used, there are still vast numbers of people who continue to have some level of persisting skin disease and continue to experience quality of life (QoL) impairment. So the question that needs to be answered, while we await further advances in our drug-based armamentarium, is how can we improve patients' QoL, beyond drugs? A working group was formed from members of the EADV Task Force on QoL and Patient Oriented Outcomes. Participants were asked to suggest all the ways in which they considered patients' QoL may be improved beyond medicines. Four groups of management approaches that may improve QoL in dermatology were identified: interventions within the dermatology service (hospitalization, multidisciplinary teams, patch testing and establishing relevant allergens and education), external services (corrective make-up, climatotherapy and balneotherapy), psychological (psychological intervention, cognitive therapy, hypnosis), lifestyle (lifestyle behavioural changes, religion and spirituality and music). The ultimate aim of therapy is to eradicate a disease in an individual and return the person's life to normal. But until the day comes when this has been achieved for every skin disease and for every patient there will be a need to support and assist many patients in additional non-pharmaceutical ways. These 'adjuvant' approaches receive too little attention while dermatologists and researchers strive for better pharmacological therapy. The different ways in which patients may benefit have been reviewed in our paper, but the reality is that most have a very poor evidence base. The research challenges that we have to meet are to identify those approaches that might be of value and to provide evidence for their optimal use. In the meantime, clinicians should consider the use of these approaches where QoL remains impaired despite optimal use of standard therapy.

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; I2  =  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; I2= 89.0%) and Infants' Dermatology Quality of Life Index (SMD = 0.30, 95% CI = - 1.04, 1.63; I2= 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.

Comparison of Personality Traits among Patients with Psoriasis, Atopic Dermatitis, and Stress: A Pilot Study

BACKGROUND

Psoriasis and atopic dermatitis are chronic skin diseases that greatly affect the quality of life. Both diseases can be triggered or exacerbated by stress.

OBJECTIVE

We aimed to differentiate personality traits between patients with chronic skin conditions and people treated for stress in a pilot study.

METHODS

Patients participating voluntarily in educational programs in Belgium and Switzerland were recruited to complete personality trait questionnaires, including the Temperament and Character Inventory (TCI) and the Tridimensional Personality Questionnaire (TPQ). A comparison was made with patients treated for work-related stress.

RESULTS

A total of 48 and 91 patients suffering from skin diseases and work-related stress, respectively, were included in the study. Based on the questionnaires, we found that dermatology patients were less persistent and impulsive than those with work-related stress. Dermatology patients also exhibited more rigidness and less focus on performance. Finally, patients with work-related stress seem more likely to change in response to health-promoting programs than patients with chronic dermatoses.

CONCLUSION

Patients with chronic skin diseases may perceive and cope with stress differently in comparison to patients with work-related stress due to inherent personality traits. Therefore, stress coping mechanisms may differ among different diseases. More research is needed into the design of educational interventions and the impact of personality traits in disease-specific groups.

Analyzing the value of an educational program for psoriasis patients: a prospective controlled pilot study

Background

Psoriasis is a chronic inflammatory skin disease associated with a reduced life-quality. Severe disease forms put the patients at risk for life-treating cardiovascular events, metabolic, and other immune-mediated disorders. Psoriasis patients are often not sufficiently informed about their condition leading to suboptimal treatment adherence and, consequently, worse patient outcome. We investigated the value of an educational program on knowledge and self-expertise about the disease in psoriasis patients in general and dependent on age and disease duration.

Methods

Regular visit psoriasis-patients were asked to participate and choose to receive an additional educational program or not. Participating patients (n = 53) filled out two questionnaires: one at study inclusion and one at the next regular visit or after the absolved educational program. Surveys included disease knowledge assessment and numeric rating scales (0–10) for self-expertise about the disease, therapy adherence, and therapy satisfaction. The Dermatology Life Quality Index (DLQI) was used to investigate the quality of life.

All continuous parameters were examined for statistically significant differences by paired t-test or unpaired t-test. Continuous parameters without Gaussian distribution were analyzed with the Wilcoxon matched pairs test or the Mann-Whitney test. For all categorical parameters, Fisher’s exact test was used.

Results

Patients who chose to be educated (n = 24) showed a significant increase in knowledge, self-expertise about the disease and amelioration of general health. No positive short-term effects were seen on the quality of life and therapy adherence. Analyzing the effect of age and disease duration, the educational program led to significant improvement of the emotional well-being in older patients (≥50 years) and with a longer disease duration as well as significant amelioration of the self-expertise about psoriasis in younger patients (< 50 years).

Conclusions

Patients who chose to participate in an educational program show a higher gain in knowledge and self-expertise about the psoriatic disease. Educational program thus might have a positive effect on the long-term management of psoriasis. Further long-term studies are needed to provide evidence for the influence educational programs have on outcome, quality of life, and treatment adherence of psoriatic patients.

Psychological Therapies in Management of Psoriatic Skin Disease: A Systematic Review

BACKGROUND

Psoriasis is a chronic, immune-mediated skin disease shown to have a multifaceted relationship with psychological factors. Because these factors have been shown to both worsen and result from psoriasis, an increasing number of studies have sought to investigate the efficacy of various psychological interventions in psoriasis management.

METHODS

A systematic review of PubMed^® and Scopus^® databases was performed for studies investigating psychological interventions in psoriasis management published from 1 January 1990 through 4 November 2018. Primary articles published in English and conveying physical treatment outcomes were included, whereas articles not describing clinical outcomes were excluded. Studies supporting intervention efficacy were graded with a level of evidence according to the Scottish Intercollegiate Guidelines Network levels of evidence.

RESULTS

A total of 28 reports studying 27 unique sets of patients receiving psychological therapies in psoriasis management were identified, including three case reports and series and 24 clinical trials, investigating 1522 patients in total. Cognitive behavioral therapy and its variants, biofeedback, meditation and mindfulness-based therapies, hypnosis, music resonance therapy, motivational interviewing, emotional disclosure, and educational and multidisciplinary approaches have been studied in the treatment of psoriasis. Although 16 randomized controlled trials were included in this review, literature is limited by heterogeneity of methodology, analyses, and outcomes. Only 4 of 27 studies (three of which investigated cognitive behavioral therapy) were rated a level of evidence of 1+ or greater. Studies, overall, have sample sizes often < 50 patients, lack follow-up past 12 months, and have attrition rates > 20%.

CONCLUSIONS

Based on assigned levels of evidence, the most promising methods of psychological intervention in psoriasis include cognitive behavioral therapy, mindfulness-based therapies, motivational interviewing, and educational and interdisciplinary interventions. Further study is needed to determine the efficacy, practicality, and economic feasibility of these treatment options for patients with psoriasis.

Lifestyle changes for treating psoriasis

BACKGROUND

Psoriasis is an inflammatory skin disease that presents with itching, red, scaling plaques; its worsening has been associated with obesity, drinking, smoking, lack of sleep, and a sedentary lifestyle. Lifestyle changes may improve psoriasis.

OBJECTIVES

To assess the effects of lifestyle changes for psoriasis, including weight reduction, alcohol abstinence, smoking cessation, dietary modification, exercise, and other lifestyle change interventions.

SEARCH METHODS

We searched the following databases up to July 2018: the Cochrane Skin Specialised Register, CENTRAL, MEDLINE, Embase, and LILACS. We also searched the China National Knowledge Infrastructure, the Airiti Library, and five trials registers up to July 2018. We checked the references of included trials for further relevant trials, and we asked the authors of the included trials if they were aware of any relevant unpublished data.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) of lifestyle changes (either alone or in combination) for treating psoriasis in people diagnosed by a healthcare professional. Treatment had to be given for at least 12 weeks. Eligible comparisons were no lifestyle changes or another active intervention.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane. The primary outcome measures were 'Severity of psoriasis' and 'Adherence to the intervention'. Secondary outcomes were 'Quality of life', 'Time to relapse', and 'Reduction in comorbidities'. We used GRADE to assess the quality of the evidence for each outcome.

MAIN RESULTS

We included 10 RCTs with 1163 participants (mean age: 43 to 61 years; 656 men and 478 women were reported). Six trials examined the effects of dietary intervention (low-calorie diet) in 499 obese participants (mean age: 44.3 to 61 years; where reported, 395 had moderate-to-severe psoriasis). One trial assessed a combined dietary intervention and exercise programme in 303 obese participants with moderate-to-severe psoriasis who had started a systemic therapy for psoriasis and had not achieved clearance after four weeks of continuous treatment (median age: 53 years). Another trial assessed a walking exercise and continuous health education in 200 participants (mean age: 43.1 years, severity not reported). Finally, two trials included education programmes promoting a healthy lifestyle in 161 participants (aged 18 to 78 years), with one trial on mild psoriasis and the other trial not reporting severity.Comparisons included information only; no intervention; medical therapy alone; and usual care (such as continuing healthy eating).All trials were conducted in hospitals and treated participants for between 12 weeks and three years. One trial did not report the treatment period. Seven trials measured the outcomes at the end of treatment and there was no additional follow-up. In two trials, there was follow-up after the treatment ended. Five trials had a high risk of performance bias, and four trials had a high risk of attrition bias.We found no trials assessing interventions for alcohol abstinence or smoking cessation. No trials assessed time to relapse. Only two trials assessed adverse events; in one trial these were caused by the add-on therapy ciclosporin (given in both groups). The trial comparing two dietary interventions to a no-treatment group observed no adverse events.The results presented in this abstract are based on trials of obese participants.Outcomes for dietary interventions versus usual care were measured 24 weeks to six months from baseline. Compared to usual care, dietary intervention (strict caloric restriction) may lead to 75% or greater improvement from baseline in the Psoriasis Area and Severity Index (PASI 75) (risk ratio (RR) 1.66, 95% confidence interval (CI) 1.07 to 2.58; 2 trials, 323 participants; low-quality evidence). Adherence to the intervention may be greater with the dietary intervention than usual care, but the 95% CI indicates that the dietary intervention might also make little or no difference (RR 1.26, 95% CI 0.76 to 2.09; 2 trials, 105 participants; low-quality evidence). Dietary intervention probably achieves a greater improvement in dermatology quality-of-life index (DLQI) score compared to usual care (MD -12.20, 95% CI -13.92 to -10.48; 1 trial, 36 participants; moderate-quality evidence), and probably reduces the BMI compared to usual care (MD -4.65, 95% CI -5.93 to -3.36; 2 trials, 78 participants; moderate-quality evidence).Outcomes for dietary interventions plus exercise programme were measured 16 weeks from baseline and are based on one trial (303 participants). Compared to information only (on reducing weight to improve psoriasis), combined dietary intervention and exercise programme (dietetic plan and physical activities) probably improves psoriasis severity, but the 95% CI indicates that the intervention might make little or no difference (PASI 75: RR 1.28, 95% CI 0.83 to 1.98). This combined intervention probably results in a greater reduction in BMI (median change -1.10 kg/m², P = 0.002), but there is probably no difference in adherence (RR 0.95, 95% CI 0.89 to 1.01; 137/151 and 145/152 participants adhered in the treatment and control group, respectively). There were no data on quality of life. These outcomes are based on moderate-quality evidence.

AUTHORS' CONCLUSIONS

Dietary intervention may reduce the severity of psoriasis (low-quality evidence) and probably improves quality of life and reduces BMI (moderate-quality evidence) in obese people when compared with usual care, while combined dietary intervention and exercise programme probably improves psoriasis severity and BMI when compared with information only (moderate-quality evidence). None of the trials measured quality of life.We did not detect a clear difference in treatment adherence between those in the combined dietary intervention and exercise programme group and those given information only (moderate-quality evidence). Adherence may be improved through dietary intervention compared with usual care (low-quality evidence). Participants generally adhered well to the lifestyle interventions assessed in the review.No trials assessed the time to relapse. Trial limitations included unblinded participants and high dropout rate.Future trials should reduce dropouts and include comprehensive outcome measures; they should examine whether dietary intervention with or without an exercise programme is effective in non-obese people with psoriasis, whether an additional exercise programme is more effective than dietary intervention alone, whether the time to relapse prolongs in people who receive dietary intervention with or without exercise programme, and whether smoking cessation and alcohol abstinence are effective in treating psoriasis.

ALIGNed on adherence: subanalysis of adherence in immune-mediated inflammatory diseases in the DACH region of the global ALIGN study

Background

Non‐adherence to medication is a challenging problem in daily clinical practice.

Objective

To assess reasons for non‐adherence in patients with chronic immune‐mediated inflammatory diseases (IMIDs) in a direct comparison including evaluation of treatment necessity and concerns.

Methods

ALIGN was a non‐interventional, multicountry, multicentre, self‐administered, cross‐sectional, epidemiologic survey study. Here, we investigate the German, Austrian and Swiss (DACH) cohort. Six hundred thirty‐one patients with different IMIDs (rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, plaque psoriasis, Crohn's disease and ulcerative colitis) under systemic therapies were evaluated concerning adherence, beliefs of necessity and concerns towards treatment in patients with IMIDs.

Results

The DACH cohort had significantly different levels of adherence depending on the IMID (P < 0.05) and the type of therapy (P < 0.05). Based on the significant influence of concerns on treatment adherence (P < 0.05) and the high belief of treatment necessity, patients could be classified in four attitudinal segments, which were unequally distributed throughout various IMIDs. High concerns had a significant influence on non‐adherence, whereas necessity did not. Older age, female sex, TNFi mono‐, conventional combination and TNFi combination therapy are positively associated with adherence.

Conclusions

In the DACH region, patients are less concerned about medication and believe in the necessity of treatment. Therefore, we suggest adapting the communication in the various patient groups.

Effect of an Educational and Psychological Intervention on Knowledge and Quality of Life among Patients with Psoriasis

Background:

Psoriasis is one of the most common skin disorders with a prevalence rate of 0.1%–3%. Chronic nature, frequent relapses, absence of permanent cure, and the cosmetic disfigurement of psoriasis have a negative impact on quality of life (QoL) by causing psychological stress. Patients with psoriasis often have unambiguous ideas about the causes, controllability, consequences, and expected time-course of their disease.

Aim:

The aim of this study is to assess the effectiveness of a video-assisted teaching program regarding psoriasis on the level of knowledge and relaxation therapy on QoL among patients with psoriasis.

Materials and Methods:

Experimental design was adapted. One hundred and four participants diagnosed with psoriasis were randomly allocated either to an experimental or to a control group. Fifty-two participants were included in each group by simple random sampling. A video-assisted teaching program on psoriasis and relaxation exercises was taught to the participants over a period of 3 months. The tools used were: Psoriasis Knowledge Assessment Questionnaire, modified psoriasis disability index, and modified psoriasis life stress inventory.

Results:

In the experimental group, the knowledge score was increased significantly from 9 ± 2.2 at baseline to 23.6 ± 1.5 after the intervention. The disability score was decreased from 15.6 to 9.9 and the stress score related to the illness was decreased from 22.8 to 16.9 after the intervention.

Conclusion:

Educational intervention about disease process and relaxation exercises was effective in improving the knowledge and QoL of patients with psoriasis.

Therapeutic patient education in children with moderate to severe atopic dermatitis: A multicenter randomized controlled trial in China

BACKGROUND

Therapeutic patient education is a continuous, systematic, patient-centered learning process to help patients and their families acquire and maintain the skills they need to manage their lives with a chronic disease. It has been proven effective in increasing treatment adherence and improving quality of life for patients with atopic dermatitis (AD) in Western countries. We introduce the first multicenter, randomized controlled clinical trial of therapeutic patient education in Chinese children with AD.

OBJECTIVES

To evaluate the effects of therapeutic patient education on the severity of AD, quality of life, and understanding and successful use of emollients in Chinese children with eczema.

METHODS

We recruited 580 children, ages 2-14 years, with moderate to severe AD from six hospitals in China. Participants were randomized (1:1) to an intervention (n = 293) or control (n = 249) group. In addition to the severity of AD, data on quality of life and a questionnaire on family and patient knowledge of emollients were evaluated at the 6-month follow-up.

RESULTS

On study completion, we found that the intervention group showed a significantly greater reduction in mean SCORing Atopic Dermatitis (P < .001) and Infant's Dermatology Life Quality Index (P = .030) scores than the control group. In addition, knowledge about the use of emollients improved significantly in the intervention group. There was no significant difference between groups in Children's Dermatology Life Quality Index scores.

CONCLUSIONS

The first randomized controlled trial of a therapeutic patient education program in China had positive long-term effects on decreasing eczema severity and improvement of quality of life in children 2-4 years of age with AD, as well as in promoting greater understanding of the use of emollients.

Addressing comorbidities in psoriatic disease

Psoriasis and PsA are associated with comorbidities including cardiovascular disease, obesity, metabolic syndrome and depression. The purpose of this study was to examine if patients recognize that they are being monitored for comorbidities associated with their condition, and to determine which physicians are managing these comorbidities. Patients with psoriasis without arthritis (PsC) and patients with PsA were recruited from the University of Toronto Psoriasis Cohort and Psoriatic Arthritis Clinic, respectively. A comorbidity questionnaire was developed through a literature review and patients completed the questionnaire at clinic visits or over the telephone. PsA patient responses were compared with information recorded by physicians at clinic visits. A total of 268 patients (103 PsC and 164 PsA) were included. Patients indicated having their blood pressure (96.3%), weight (94.4%), blood sugar (75%) and cholesterol (79.5%) levels checked, with PsA patients indicating being checked more frequently than PsC patients. PsA patients were most uncertain about whether their blood sugar and cholesterol levels were checked by physicians. The highest correlation between patient responses and physician records occurred for medications for diabetes, depression and hypercholesterolemia. Patients indicated their family physician were most responsible in monitoring the comorbidities. Overall, patients documented being moderately well screened for most comorbidities and were most unsure about having their blood sugar and cholesterol levels monitored. Patient education and records should be improved at clinic visits, as there are discrepancies between patient responses and physician records regarding the presence and treatment of comorbidities.

Systematic review of self-management interventions for people with eczema

Eczema is a common long‐term condition, but inadequate support and information can lead to poor adherence and treatment failure. We have reviewed the international literature of interventions designed to promote self‐management in adults and children with eczema. MEDLINE, MEDLINE in process, Embase, CINAHL and the Global Resource for EczemA Trials database were searched from their inception to August 2016, for randomized controlled trials. Two authors independently applied eligibility criteria, assessed risk of bias for all included studies and extracted data. Twenty studies (3028 participants) conducted in 11 different countries were included. The majority (n = 18) were based in secondary care and most (n = 16) targeted children with eczema. Reporting of studies, including descriptions of the interventions and the outcomes themselves, was generally poor. Thirteen studies were face‐to‐face educational interventions, five were delivered online and two were studies of written action plans. Follow‐up in most studies (n = 12) was short term (up to 12 weeks). Only six trials specified a single primary outcome. There was limited evidence of effectiveness. Only three studies collected and reported outcomes related to cost and just one study undertook any formal cost‐effectiveness analysis. In summary, we have identified a general absence of well‐conducted and well‐reported randomized controlled trials with a strong theoretical basis. Therefore, there is still uncertainty about how best to support self‐management of eczema in a clinically effective and cost‐effective way. Recommendations on design and conduct of future trials are presented.

What's already known about this topic?

Eczema requires a high degree of self‐management by patients.

Adherence to eczema treatments, and hence control of symptoms, can be poor.

There is uncertainty about how best to support self‐management in a clinically effective and cost‐effective way.

What does this study add?

A wide range of interventions designed to promote self‐management have been evaluated in 20 studies across 11 different countries.

Reporting of the design and conduct of these studies is generally poor, and explicit theory describing how interventions are expected to improve care is uncommon.

What works best for people with eczema and whether it is cost‐effective is unknown.

Recommendations for future trials are made.

Multidisciplinary interventions in the management of atopic dermatitis

Atopic dermatitis (AD) is the most common pediatric skin disease. AD has a significant effect on patient and family quality of life caused by intense pruritus, sleep disruption, dietary and nutritional concerns, and psychological stress associated with the disease and its management. Multidisciplinary approaches to AD care have been developed in appreciation of the complex interplay among biological, psychological, behavioral, and dietary factors that affect disease control and the wide range of knowledge, skills, and support that patients and families require to effectively manage and cope with this condition. Common components of multidisciplinary treatment approaches include medical evaluation and management by an AD specialist, education and nursing care, psychological and behavioral support, and nutritional assessment and guidance. Models of care include both clinical programs and structured educational groups provided as adjuncts to standard clinical care. Available evidence suggests beneficial effects of multidisciplinary interventions in improving disease severity and quality of life, particularly for patients with moderate-to-severe disease. Additional research is needed to identify the best candidates for the various multidisciplinary approaches and evaluate the cost-effectiveness of these programs.

Psychological and Educational Interventions for Atopic Dermatitis in Adults: A Systematic Review and Meta-Analysis

Psychological and educational interventions are valuable adjuncts in the management of adult atopic dermatitis. We performed a systematic review and meta-analysis of randomised controlled trials (RCTs) of the efficacy of these interventions. Twelve articles published between 1986 and 2013 were identified through electronic searches. The methodological quality was assessed according to the Cochrane Handbook for Systematic Reviews of Interventions, version 5.1.1 (Higgins & Green, 2015). A random-effects model was used to estimate the standardised mean difference (SMD). No significant difference was found in eczema severity determined in three RCTs (124 participants; SMD, -0.29; 95% CI [-0.64, 0.07]) and dropout rate in five RCTs (198 participants; relative risk, 0.66; 95% CI [0.20, 2.17]). Education via online video was significantly superior to handouts in ameliorating eczema severity in one RCT (80 participants). We conclude that, rather than a combination of these interventions with conventional therapy being of no value, the data did not have sufficient power to provide evidence-based conclusions.

Atopic Dermatitis Disease Education

Atopic dermatitis is a skin condition that is increasing burdensome to patient's lives. Patients require effective strategies to cope with the condition as well as the vast amount of new research that is coming to the forefront. This chapter discusses the patient education aspect of atopic dermatitis. We drew from various sources-such as peer-reviewed academic journals, online groups, and organizational websites-to provide a brief survey of the available types of patient educational resources. We discuss educational materials and interventions, such as workshops and support groups. In addition to the content of the workshops, we also explore the importance of their facilitators. We also review organizations in the US that pertain to atopic dermatitis and eczema care, such as the National Eczema Association and the American Academy of Dermatology. Lastly, we survey the role of technology-such as social media, web-based applications and teledermatology-in facilitating patient education. Despite the promising impacts of these technological interventions in the way patients consume educational materials, we also acknowledge that they are not widely used.

Educational interventions to improve quality of life in people with chronic inflammatory skin diseases: systematic reviews of clinical effectiveness and cost-effectiveness

BACKGROUND

Inflammatory skin diseases include a broad range of disorders. For some people, these conditions lead to psychological comorbidities and reduced quality of life (QoL). Patient education is recommended in the management of these conditions and may improve QoL.

OBJECTIVES

To assess the clinical effectiveness and cost-effectiveness of educational interventions to improve health-related quality of life (HRQoL) in people with chronic inflammatory skin diseases.

DATA SOURCES

Twelve electronic bibliographic databases, including The Cochrane Library, MEDLINE and EMBASE, were searched to July 2014. Bibliographies of retrieved papers were searched and an Advisory Group contacted.

REVIEW METHODS

Systematic reviews were conducted following standard methodologies. Clinical effectiveness studies were included if they were undertaken in people with a chronic inflammatory skin condition. Educational interventions that aimed to, or could, improve HRQoL were eligible. Studies were required to measure HRQoL, and other outcomes such as disease severity were also included. Randomised controlled trials (RCTs) or controlled clinical trials were eligible. For the review of cost-effectiveness, studies were eligible if they were full economic evaluations, cost-consequence or cost analyses.

RESULTS

Seven RCTs were included in the review of clinical effectiveness. Two RCTs focused on children with eczema and their carers. Five RCTs were in adults. Of these, two were of people with psoriasis, one was of people with acne and two were of people with a range of conditions. There were few similarities in the interventions (e.g. the delivery mode, the topics covered, the duration of the education), which precluded any quantitative synthesis. Follow-up ranged from 4 weeks to 12 months, samples sizes were generally small and, overall, the study quality was poor. There appeared to be positive effects on HRQoL in participants with psoriasis in one trial, but no difference between groups in another trial in which participants had less severe psoriasis. Carers of children in one RCT of eczema showed improvement in HRQoL; however, in a RCT evaluating a website intervention there were no demonstrable effects on HRQoL. Neither the RCT in those adults with acne nor the RCT in those adults with mixed skin conditions demonstrated an effect on HRQoL. One RCT reported subgroups with atopic dermatitis or psoriasis and education was effective for psoriasis only. Other outcomes also showed mixed results. It is unclear how clinically meaningful any of the observed improvements are. Three studies of cost-effectiveness were included. The interventions, comparators and populations varied across the studies and, overall, the studies provided limited information on cost-effectiveness. The studies did provide detailed information on resources and costs that could be useful to inform a future cost-effectiveness evaluation in this area.

LIMITATIONS

The application of the inclusion criterion around whether the interventions were aimed at improving HRQoL or the inference that they could improve HRQoL was difficult as information was rarely reported.

CONCLUSIONS

There is uncertainty regarding whether educational interventions addressing issues that could improve HRQoL in people with chronic skin conditions are effective. Tentative conclusions about the best approach to delivering these kinds of interventions are that face-to-face, group, sessions may be beneficial; however, text messages may also be effective. Delivery over a period of time and by a multidisciplinary team may also be associated with positive outcomes. There is uncertainty over whether or not educational interventions are cost-effective.

Education to improve quality of life of people with chronic inflammatory skin conditions: a systematic review of the evidence

Patient and carer education has been proposed as a way of improving health-related quality of life (HRQoL) among people with chronic inflammatory skin conditions. This systematic review aimed to assess the effects of education that specifically addresses HRQoL among people with chronic inflammatory skin conditions. We searched 12 literature databases and other sources (up to July 2014). Seven randomized controlled trials (RCTs) met the review inclusion criteria. Data from these RCTs were extracted and critically appraised. Two RCTs showed that for psoriasis in adults, group-based and text message education (as adjuncts to usual care) resulted in better HRQoL and disease severity outcomes than comparators, respectively. One RCT found that group-based education for children with eczema (atopic dermatitis) and their parents resulted in greater improvements in parents' HRQoL and in the children's disease severity than no education at 12 months. The remaining RCTs evaluated an educational session for psoriasis, a website for carers of children with eczema, information on skincare and make-up use given to women with acne, and an itch-coping programme for a range of conditions, all as adjuncts to usual care. None of these RCTs found statistically significant effects on HRQoL or disease severity compared with usual care. Common features of the effective interventions were long delivery (over 6 weeks to 3 months) and delivery by a multidisciplinary team. Overall, the evidence base is currently limited and generally has an unclear risk of bias. There is a need for more large RCTs evaluating piloted and theory-based interventions.

Getting under the Skin: Report from the International Psoriasis Council Workshop on the Role of Stress in Psoriasis

Psoriasis is a chronic inflammatory skin condition with significant physical and psychosocial comorbidity. A workshop of leading experts in dermatology and psychology with the purpose of better understanding the current role of psychological comorbidities in psoriasis was held by the International Psoriasis Council in November 2013. The role of stress reactivity with a focus on the hypothalamic-pituitary-adrenal axis was emphasized. While cognitive behavioral therapy remains the most extensively studied and successful treatment strategy in patients with psoriasis and various psychological comorbidities, new and innovative interventions such as online-based therapies have recently emerged. Strategies and recommendations toward approaching psychological comorbidities are discussed.

A multileveled approach in psoriasis assessment and follow-up: A proposal for a tailored guide for the dermatological practice

BACKGROUND

Psoriasis is a complex and heterogeneous disease resulting from interactions between genetic, immunological, and environmental factors. To make the most optimal treatment decision, the dermatologist must therefore have a detailed overview of the patient's history and lifestyle.

OBJECTIVES

We sought to offer an overview of the various relevant aspects in clinical dermatological assessment of psoriasis patients, emphasizing the importance of a multidisciplinary and integrated clinical approach.

METHODS

We gathered information on psoriasis management and developed a tailored checklist covering all health-related aspects associated with psoriasis.

RESULTS

Demographics, personal and family history were elaborately described as well as drug history to discuss how they affect psoriasis management. Relevant patient information such as the vaccination status or cardiovascular profile were included in the checklist as well and treatment recommendations were adapted and updated in accordance with evidence-based literature. This checklist also emphasizes the importance of drug surveillance, proper follow-up and specialist referral, and why the dermatologist needs to address these health-related aspects when assessing psoriasis patients, going beyond optimal skin care.

CONCLUSIONS

Our comprehensive overview can be used as a consultation checklist for good clinical practice in psoriasis patient management and aid in treatment decision.

A Review of Multidisciplinary Interventions in Atopic Dermatitis

Multidisciplinary interventions have been developed for patients with atopic dermatitis (AD) and their families, with the aim of improving outcomes such as disease control, adherence, and quality of life. We reviewed the content of different multidisciplinary approaches to intervention for AD and evidence for their impact on key outcome measures. We also provided data from our multidisciplinary outpatient program for pediatric AD. Studies included in the review suggest benefits of multidisciplinary interventions as models of treatment or adjuncts to standard medical care, with a positive impact on outcomes including disease severity and itching/scratching. There were limitations to existing studies, including heterogeneous methods used to assess quality of life outcomes across studies and lack of controlled studies assessing the outcome of clinical care programs. Further research will be useful in assessing the impact of multidisciplinary interventions on important outcomes such as treatment adherence and sleep, identifying the elements of multidisciplinary interventions that are most critical for improved outcomes, and identifying the best candidates for multidisciplinary intervention approaches.

Novel investigational therapies for atopic dermatitis

Introduction: Atopic dermatitis (AD) is a common skin disease. Although most patients are well served by existing therapies, a subset of patients with severe AD are still not adequately treated. An improved understanding of the pathogenic mechanisms behind the disease has led to the development of a range of potential new drugs for this indication. Areas covered: The authors provide a narrative review of the drugs in Phase II trials listed on Clinicaltrials.gov. The authors supplement this information with recently published literature located through PubMed. The main target of new treatments appears to be the inflammation process, whereas drugs aimed at reducing itching or increasing the barrier function are fewer to nonexistent. A wide range of drugs, including small molecules and antibodies, are being tested. Expert opinion: The focus on inflammation is not only driven by the limitations posed by our current understanding of biology, but also by the broader scope of these drugs, which may be used in other diseases. In alignment with the recent drug development of other dermatological diseases, antibodies directed at key molecules in the pathogenesis of AD appear to be the most promising.

Atopic dermatitis: an evidence-based treatment update

BACKGROUND

Atopic dermatitis (AD) is a common inflammatory disorder of skin with significant comorbidities. AD care often requires a combination of treatment approaches, including emollients, topical steroids, systemic immunosuppressants and/or phototherapy.

PURPOSE

Our purpose was to review recent randomized controlled trials (RCT) and systematic reviews of AD treatments.

METHODS

A MEDLINE search was performed focusing on RCTs of AD treatments, with a sample size ≥ 15, and systematic reviews published from 2011 to 2013, limited to the English language. A total of 53 manuscripts met the inclusion/exclusion criteria, including 44 RCTs and nine systematic reviews.

RESULTS

Investigator-initiated RCTs support the use of the systemic agents cyclosporine, methotrexate, azathioprine and mycophenolate mofetil. In one RCT, petrolatum was found to be as effective as creams containing ceramides or glycyrrhetinic acid. Additional therapeutic approaches supported by RCTs include balneotherapy, oral and/or topical probiotics, nutritional interventions, vitamin D with or without vitamin E supplementation, as well as several new topical and complementary medicines.

CONCLUSIONS

Advances have been made with respect to AD treatment in the past few years through the use of well designed RCTs and comparative efficacy studies. However, more well designed RCTs and investigator-initiated studies are needed in order to improve the care of AD patients.

Non-pharmacologic therapies for atopic dermatitis

Atopic dermatitis (AD) continues to present significant therapeutic challenges, especially in severe cases. Navigating the line between risk and benefit can be difficult for more powerful medications such as immunosuppressants, but non-pharmacologic treatments are often overlooked and underutilized. Creative application of these more physical therapies can serve to minimize the pharmacologic treatments and their side effects, and possibly even create synergy between modalities, to maximize benefit to the patient.

Limited evidence of the effects of patient education and self-management interventions in psoriasis patients: a systematic review

OBJECTIVE

To describe the contents of educational and self-management programmes for patients with psoriasis, and to evaluate their effects.

METHODS

A systematic review of randomized controlled trials (RCTs), quasi-randomized trials and controlled clinical trials identified by a systematic literature search. Risk of bias was assessed by two independent reviewers and interventional effects were summarized descriptively and by meta-analysis.

RESULTS

Nine studies were included, which ranged from single brief interventions to long complex multidisciplinary programmes. Four RCTs with adequate sequence allocation were included to analyze interventional effects. One RCT compared two different educational programmes and found no differences between groups. The results of three trials that focused on combinations of education and self-management were heterogeneous. One RCT based on a 12-week comprehensive programme reported statistically significant effects (p<0.05) on disease severity and health-related quality of life. Two RCTs with less comprehensive programmes reported no effects on HRQoL.

CONCLUSION

This review showed that little evidence is available to support the effects of educational and self-management interventions in patients with psoriasis that are studied in RCTs. There is a significant lack of focused self-management and, compared with other chronic conditions, there appear to be few effective disease-specific tailored educational programmes for psoriasis.
