The role of the nurse in the care and management of patients with atopic dermatitis.

BACKGROUND: The purpose of this paper is to provide an overview of key aspects of specialised dermatology nursing practice in the management of patients with moderate to severe atopic dermatitis. The role of dermatology nurse specialists in supporting patients and promoting disease understanding, education and treatment adherence continues to evolve. As features of specialised nursing care can also inform other nursing staff in a wide range of care settings, an overview of key components is examined. Observations presented are from a pan-European perspective and represent the collected view of a group of dermatology nurse specialists, dermatologists and patient advocates following two round-table discussions. MAIN BODY: Atopic dermatitis is a common, chronic, inflammatory disease characterised by erythematous/scaling skin lesions, with often intense pruritus. Disease course is cyclic with periodic disease flares of varying intensity, presenting management challenges to patients and families. Dermatology nurse specialists play a key role in providing education and substantial patient support to improve treatment outcomes and quality of life to patients and their family, delivered within a multidisciplinary team framework. Nurse-led education and 'eczema schools' are of benefit in reducing disease severity and improving quality of life by enhancing self-management, adherence and patient engagement. eHealth tools, such as patient portals or online training platforms, can provide online learning, individualised education, and help to improve engagement. These and other initiatives, such as written action plans, are all essential to improve or maintain treatment adherence, self-management and quality of life. CONCLUSIONS: Dermatology nurse specialists play a central role in the assessment and management of moderate to severe atopic dermatitis patients and families. This places them in an ideal position to build strong and often long-term relationships with patients and parents. Such engagement promotes trust, assists in setting realistic expectations of treatment and outcomes, and enhances self-management and engagement in their own care. Providing emotional support, as well as formal and systematic education (including individualised practical advice) all contribute to improved treatment adherence and can enhance the quality of life of patients and their families throughout the course of this long-term condition.

Smoking and common mental disorders in patients with chronic conditions: An analysis of data collected via a web-based screening system.

OBJECTIVE: Smoking is the largest preventable cause of death and disability in the UK and remains pervasive in people with mental disorders and in general hospital patients. We aimed to quantify the prevalence of mental disorders and smoking, examining associations between mental disorders and smoking in patients with chronic physical conditions. METHOD: Data were collected via routine screening systems implemented across two London NHS Foundation Trusts. The prevalence of mental disorder, current smoking, nicotine dependence and wanting help with quitting smoking were quantified, and the relationships between mental disorder and smoking were examined, adjusting for age, gender and physical illness, with multiple regression models. RESULTS: A total of 7878 patients were screened; 23.2% screened positive for probable major depressive disorder, and 18.5% for probable generalised anxiety disorder. Overall, 31.4% and 29.2% of patients with probable major depressive disorder or generalised anxiety disorder respectively were current smokers. Probable major depression and generalised anxiety disorder were associated with 93% and 44% increased odds of being a current smoker respectively. Patients with depressive disorder also reported higher levels of nicotine dependence, and the presence of common mental disorder was not associated with odds of wanting help with quitting smoking. CONCLUSION: Common mental disorder in patients with chronic physical health conditions is a risk factor for markedly increased smoking prevalence and nicotine dependence. A general hospital encounter represents an opportunity to help patients who may benefit from such interventions.

Biological therapies for the treatment of severe psoriasis in patients with previous exposure to biological therapy: a cost-effectiveness analysis.

BACKGROUND: Biologic therapies have revolutionised the care of patients with psoriasis, although they come at significant extra cost. Guidance on their use in the UK National Health Service (NHS) has so far focused on patients who are "biologic naive", yet a minority of patients have poor response and require further treatment. OBJECTIVES: To assess the potential cost effectiveness of sequential biologic therapies in patients with psoriasis who have been exposed to previous biologic therapy. METHODS: A two-part model with a 10-year time horizon was built to model an initial 13.5-week "trial" phase and a longer-term "treatment" period with annual Markov cycles. Psoriasis Area and Severity Index (PASI) response rates from subgroup analyses of three randomised placebo-controlled trials evaluating biologic agents were considered. A meta-analysis of these data provided probabilities of achieving PASI response (50/75/90) in the short term, and published evidence and assumptions were used to predict outcomes over the longer term. Benefits were measured in quality-adjusted life years (QALYs), and costs (2013-14) to the UK NHS included drugs, administration, monitoring, and hospitalisation. Costs and benefits were discounted 3.5 % per annum. Cost effectiveness of sequential biologic therapy was measured using an incremental cost-effectiveness ratio (ICER) compared to best supportive care (BSC). Extensive sensitivity analyses were performed to assess the impact of alternative assumptions on the results. RESULTS: Results indicate that over 10 years, switching to a second biologic following intolerance to or failure of a first is likely to generate more QALYs than BSC, but at a higher cost. Base case results suggest the ICER of the second biologic compared to BSC is £17,681 per QALY; however, sensitivity analyses indicate that changes in the efficacy of BSC, drug costs, dropout rates, and rates of hospitalisation have a significant impact, causing the ICER to range from less than £10,000 to over £50,000 per QALY. CONCLUSIONS: Further biologic therapy for patients with psoriasis who have previously been treated with biologic therapy may be cost effective, although there is considerable uncertainty in the results. Future studies should be designed to evaluate the clinical efficacy of biologic therapies in this subgroup with particular attention given to short-term and longer-term responses.

Psychological and educational interventions for atopic eczema in children.

BACKGROUND: Psychological and educational interventions have been used as an adjunct to conventional therapy for children with atopic eczema to enhance the effectiveness of topical therapy. This is an update of the original Cochrane review. OBJECTIVES: To assess the effect of psychological and educational interventions for atopic eczema in children. SEARCH METHODS: We updated our searches of the following databases to January 2013: the Cochrane Skin Group Specialised Register, CENTRAL in The Cochrane Library (2012, Issue 12), MEDLINE (from 1946), EMBASE (from 1974), OpenGrey, and PsycINFO (from 1806). We also searched six trials registers and checked the reference lists of included and excluded studies for further references to relevant randomised controlled trials (RCTs). SELECTION CRITERIA: Randomised controlled trials of psychological or educational interventions, or both, used to assist children and their carers in managing atopic eczema. DATA COLLECTION AND ANALYSIS: Three authors independently applied eligibility criteria, assessed trial quality, and extracted data. A lack of comparable data prevented data synthesis, and we were unable to conduct meta-analysis because there were insufficient data. MAIN RESULTS: We included 10 RCTs, of which 5 were new to this update; all interventions were adjuncts to conventional therapy and were delivered in primary- and secondary-care settings. There were 2003 participants in the 9 educational interventions and 44 participants in the 1 psychological study. Some included studies had methodological weaknesses; for example, we judged four studies to have high risk of detection bias, attrition bias, or other bias. Our primary outcomes were participant-rated global assessment, reduction in disease severity (reported as objective SCORAD (SCORing Atopic Dermatitis)), and improvement in sleep and quality of life. No study reported participant-rated global assessment or improvement of sleep.The largest and most robust study (n = 992) demonstrated significant reduction in disease severity and improvement in quality of life, in both nurse- and dermatologist-led intervention groups. It provided six standardised, age-appropriate group education sessions. Statistically significant improvements in objective severity using the SCORAD clinical tool were recorded for all intervention groups when compared with controls. Improvements in objective severity (intervention minus no intervention) by age group were as follows: age 3 months to 7 years = 4.2, 95% confidence interval (CI) 1.7 to 6.8; age 8 to 12 years = 6.7, 95% CI 2.1 to 11.2; and age 13 to 18 years = 9.9, 95% CI 4.3 to 15.5. In three of five studies, which could not be combined because of their heterogeneity, the objective SCORAD measure was statistically significantly better in the intervention group compared with the usual care groups. However, in all of the above studies, the confidence interval limits do not exceed the minimum clinically important difference of 8.2 for objective SCORAD.The largest study measured quality of life using the German 'Quality of life in parents of children with atopic dermatitis' questionnaire, a validated tool with five subscales. Parents of children under seven years had significantly better improvements in the intervention group on all five subscales. Parents of children aged 8 to 12 years experienced significantly better improvements in the intervention group on 3 of the 5 subscales. AUTHORS' CONCLUSIONS: This update has incorporated five new RCTs using educational interventions as an adjunct to conventional treatment for children with atopic eczema. We did not identify any further studies using psychological interventions. The inclusion of new studies has not substantially altered the conclusions from the original review. The educational studies in both the original review and this update lack detail about intervention design and do not use a complex interventions framework. Few use an explicit theoretical base, and the components of each intervention are not sufficiently well described to allow replication. A relative lack of rigorously designed trials provides limited evidence of the effectiveness of educational and psychological interventions in helping to manage the condition of atopic eczema in children. However, there is some evidence from included paediatric studies using different educational intervention delivery models (multiprofessional eczema interventions and nurse-led clinics) that these may lead to improvements in disease severity and quality of life. Educational and psychological interventions require further development using a complex interventions framework. Comparative evaluation is needed to examine their impact on eczema severity, quality of life, psychological distress, and cost-effectiveness. There is also a need for comparison of educational interventions with stand-alone psychosocial self-help.  

The assessment and management of psoriasis.

Psoriasis is a long-term, inflammatory skin condition that affects around 1.3-2.2% of the UK population. Nurses involved in the assessment and treatment of people with psoriasis should take into account not only the condition's physical effects but also the increased risk of health problems linked to it and its psychological effects. This article highlights National Institute for Health and Clinical Excellence guidance, primarily for non-specialist practitioners.

A multicenter study of the pharmacokinetics of tacrolimus ointment after first and repeated application to children with atopic dermatitis.

The pharmacokinetics of tacrolimus after first and repeated application of 0.1% tacrolimus ointment were evaluated in 39 children, aged 6-12 y, with moderate to severe atopic dermatitis. The patients were grouped according to the size of the affected body surface area to be treated: Group 1< or =1500 cm(2); Group 2 >1500 cm(2) < or =3000 cm(2); Group 3 >3000 cm(2) < or =5000 cm(2). Serial blood samples to calculate pharmacokinetic parameters taken on Day 1 (first ointment application) and Day 14 (last application) showed minimal systemic exposure to tacrolimus. Overall, 92% of the blood samples assayed contained tacrolimus concentrations below 1 ng per mL and 17% of samples were below 0.025 ng per mL, the lower limit of quantification. Systemic exposure to tacrolimus varied between patients and tended to increase proportionally as the size of the treated body surface area increased. Absorption decreased with time as the skin lesions healed and there was no evidence of systemic accumulation. The mean apparent half-life of tacrolimus (t(1/2, z)) was 66+/-27 h (range 19-125 h). Most patients experienced substantial clinical improvement in their atopic dermatitis. There were no clinically relevant changes in laboratory values, and the most frequently reported adverse event was skin burning, which resolved quickly as the skin condition improved.
