“How can we achieve 'Healthy skin for all’?” Jonathan Jeyatheswaran Introduction Skin disease is one of the most common human illnesses, impacting on all cultures and occurring at all ages, with three skin conditions in the ten most prevalent diseases worldwide.1 International dermatology organisations have posed the question of how to achieve healthy skin for all, with emphasis placed on increasing awareness of the importance of skin and delivery of care to those in need, especially developing countries.2,3 To address this question further, topics including prevention, research funding and dermatology training will be analysed as factors for achieving healthy skin for all. Developing Countries On a global scale, skin conditions were the fourth leading cause of nonfatal disease burden in both low and high-income countries, emphasising need for skin prevention and treatment in future global health prevention strategies.1 In deprived regions there is a mismatch between demand and supply in terms of dermatologists, healthcare workers, buildings and equipment.4 For example, Ethiopia has a population of around 80 million people serviced by approximately 22 dermatologists practicing in urban areas, leaving Ethiopia’s rural population without adequate care.5 With healthcare focused on life-threatening diseases, concerns about skin disease may not be addressed leading to infection, disfigurement and community ostracism.6 International task groups could be sent to these areas to draw up guidelines on carrying out health needs 1 assessments that meet international requirements and funding should be available to train more dermatologists to practice in resource-poor regions.4,7 Training healthcare professionals could be aided through voluntary work.6 Health Volunteers Overseas (HVO) has worked in partnership with the American Academy of Dermatology, providing opportunities in developing countries for dermatologists to share their skills by training local health providers in basic skin care through bedside and didactic teaching.6 Training for dermatologists and health workers should be specific to population need, with skin infections more common in developing countries, particularly children.6,8,9 Involving more women in dermatology education and training has helped in fostering improvements in skin care for women and children worldwide.10 The purpose of the International Foundation of Dermatology (IFD) is to improve dermatology education, training and programs such as the Regional Dermatology Training Centre (RDTC) in Tanzania.7 Organisations such as IFD have built strong relationships with industry, resulting in pharmaceutical companies aiding advancements of international humanitarian initiatives such as Global Alliance for the Elimination of Lymphatic Filariasis.7,11-13 Organisations similar to IFD must continue to be funded and efforts made to expand networks in dermatology between international organisations, to enable greater exchange of research, which could result in more effective affordable treatment.7,14 Such collaborations could result in the formation of an international resource, providing access to data permitting greater understanding of global issues to the wider dermatology community.7 2 Teledermatology services provide a diagnostically reliable method of increasing access to expertise in resource-poor regions.15,16 Mobile teledermatology has been introduced to overcome lack of internet in developing countries.17-19 Established teledermatology programs should be sustainable so a long-term positive contribution is made to the community such as the Panamanian Telemedicine and Telehealth Program.20 High standards of communication with referring providers and teledermatology training are necessary to support sustainable practices.15,21 Causes and clinical presentation of skin disease can be influenced by culture and religion, particularly in developing countries.22,23 Allergic contact dermatitis has been reported in Hindu women who wear the bindi, a red adhesive disc worn on the forehead.22 In Asia, skin diseases such as vitiligo lead to emotional lability, with a great psychosocial impact on women, where beauty is valued in the arranged marriage market.24 Therefore, clinicians should consider patient’s cultural heritage and religious practices to aid diagnosis and management of skin disease.24,25 3 Prevention and Standards of Care Approximately 2,200 deaths per year from skin cancer are mostly due to malignant melanoma in the United Kingdom (UK).26 Incidence of melanoma and non-melanoma skin cancer has increased over the past 50 years in fair skinned populations in Europe, North America and Australia.27-30 Nevertheless, there should be patient education about skin cancer regardless of race.31,32 Primary risk factors for developing skin cancer include degree of sun exposure, skin type and family history of skin cancer.33 However, new risk factors can emerge, with more cases of melanoma reported in young adults.34,35 De Vries et al. (2012) identified potential risk factors for skin cancer with consumption of specific food items, medication use and stress.36 Relationships between skin cancer and other conditions have been suggested such as that of melanoma and Parkinson’s disease.37,38 Research and reviews of literature into risk factors of skin diseases are continuously required to improve standards of prevention. Prevention strategies are an effective method of maintaining healthy skin as highlighted by increased percentage survival rates from melanoma when detected in its early stages.39-41 There has been greater promotion of sunbed use, especially amongst adolescent women, with endorsement of sunbeds by celebrities.42 Skin cancer prevention should focus on changing the beliefs of tanning appeal, emphasise the importance of sunscreen use and highlight the need for skin self-examination.30,43 There should be promotion of ultraviolet radiation protection through education (the SunSmart website) and regular surveys of sun exposure.44-47 Implementing these methods will save lives, reduce 4 morbidity and generate major health system cost savings.48 Regular assessments must be made of people’s awareness and attitudes to skin cancer prevention. Reviewing methods used to raise awareness in primary care, workplaces, the internet and through international campaigns such as Euromelanoma is required.49-52 Consequently, standards of prevention can be improved upon locally and globally. Similar prevention methods could be implemented for other skin conditions such as need for smoking cessation and education about how to use topical treatments for psoriasis patients.53-57 Skin conditions could increase the risk of patients suffering from other diseases such as the possible link between psoriasis and cardiovascular disease.58-61 Accessible public information about common skin conditions is provided by organisations such as The Psoriasis Association and National Eczema Society.62,63 Dermatologists and other health professionals should make patients aware of these organisations, which provide reliable and updated information and raise awareness of new research findings. Clinical guidelines offer the opportunity for standardisation of diagnostic procedures, their use guarantees equal access of patients to medical services and they represent a scaffold for inexperienced physicians.64 These guidelines should be regularly evaluated. Randomised control trials and systematic reviews should be used when developing clinical guidelines and establishing treatment efficacy.65,66 A wide range of non-clinical factors including patient, clinician and practice-related factors can influence clinical decision-making.67 Examples of 5 these are treatment adherence and time constraints in clinic.67 Understanding of non-clinical influences on decision-making is of principal importance.67 Clinical audits form part of clinical governance and are necessary for safeguarding high standards of care.68,69 Mohs micrographic surgery audits collected data including the recurrence rates of basal cell carcinoma and complications of surgery.68,69 This data could help improve aspects of care in the future and highlights the importance of auditing in dermatology.68,69 Self-management, Outcome Measures and Psychodermatology Self-management is necessary for controlling skin conditions. For example, for patients with high risk of melanoma, systematic self-examination with skin selfphotography is important and patients should remember to visit a trained doctor yearly to be examined.70,71 Furthermore, patients suffering with skin disease have to be fully aware of how to use treatments effectively and must be conscious of the side effects associated with certain therapies. Patient-centred communication and education in dermatology enhances levels of patient care including self-management, fufills professional competencies requirements, reduces medical errors, and improves health outcomes and patient satisfaction.72 Dermatologists must be taught effective techniques for verbal and non-verbal communication, especially for difficult conversations in dermatology practice.72 Outcome measures are frequently used, such as quality of life (Dermatology Life Quality Index) or severity (Psoriasis Area and Severity Index), and not process 6 measures that may assess key factors influencing such outcomes.73 Chronic disease intervention should begin with assessment of patient’s prior knowledge, personal competence, and patient identified outcomes such as the PersonCentred Dermatology Self-Care Index (PeDeSI) assessment which considers the education and support needs of patients with long-term dermatological conditions and aims to promote treatment concordance.73 Skin conditions including acne and psoriasis can affect psychological wellbeing.74 Acne may be associated with suicide, depression and higher levels of unemployment.75 Psoriasis flare-ups can occur due to significant life events.76-78 A survey provides evidence suggesting that dermatologists are underprepared to treat psychocutaneous disorders, with a lack of patient access to psychiatric support noted in dermatology departments in the UK.79,80 Greater focus should be placed on training dermatologists in pychodermatology. Treatments such as cognitive-behavioural methods, hypnosis or progressive relaxation can help to counteract stress and prevent flare-ups.81,82 Government and Commissioning Care Quality of skin care may be at risk from political agendas focused on limitation and prioritisation. It is important that international organisations have a role in analysing healthcare reforms and collaborate to make clinical guidelines.7,83 The aim of governments should be to provide the most effective and affordable dermatology care to meet the population’s need. 7 Clinical commissioning groups have the obligation to obtain advice from healthcare professionals and involve patients and the public in decisions regarding delivery of skin care. Professional organisations such as the British Association of Dermatologists (BAD) should have a primary role in illustrating to government complexities in commissioning as shown by BAD, The Lessons for the NHS: Commissioning a Dermatological Service, to improve the framework for delivering efficient skin care.84,85 . Research The United States (US) federal deficit may see a decrease in National Institute of Health (NIH) research money and Medicare funding of dermatology residency positions.86 In 2006 the UK Clinical Research Collaboration published an analysis of directly-funded UK research portfolios of the 11 largest government and charity funders of health-related research.87 Of 20 health categories, ‘skin’ ranked eighteenth for funding.87 At the 2010 UK annual scientific meeting of The Society for Academic Primary Care, of 257 abstracts featured, only one was dermatological.87 Therefore, efforts must be made to improve dermatology research funding including in countries with established healthcare systems.87 Dermatology must find new ways to fund research, possibly by encouraging investigators to collaborate, making research more efficient.86 Funding should follow the approach of the Milken prostate cancer model, which stimulates research by cutting the waiting time for grant money, emphasises funding of 8 therapy-driven ideas, holds researchers accountable for results, and demands collaboration across all disciplines and among institutions, private industry, and academia.86 Another example is the Dermatology Foundation in the US that has successfully supported future leaders who have chosen the study of skin health and extended funding to important fields including paediatric dermatology and dermatopathology.88 Furthermore, the foundation tracks career outcomes of those who have received funding through career development awards (CDAs), with a survey showing 80% of 181 past recipients of CDAs currently holding positions in academic medicine.88,89 Primary care research in the UK is supported through the National School for Primary Care Research and Primary Care Research Networks.87,90 Researchers engage with the UK Dermatology Clinical Trials Network, which provides support for developing trial ideas.87 Challenges facing expansion of primary care dermatology research are engaging general practitioners (GPs) who do not have a specific research interest and minimising the additional workload involved.87,90 Interest could be raised in dermatology through more learning opportunities of skin conditions in primary care settings at an undergraduate level.87,91 9 Training and The Future Dermatology is a specialty reliant on excellent perceptual skills and pattern recognition (non-analytical pattern recognition (NAPR)), with exposure to many cases necessary.92,93 In the UK, undergraduate training is limited to only a few weeks despite around 900,000 patients being referred from primary care to hospital care each year.92 Cutaneous malignancies account for over a quarter of all new cancers diagnosed in the UK.93 GPs are responsible for the initial assessment of skin lesions (10-15% of primary care cases).91,92 However, GPs need to see dermatology cases frequently enough to remain competent.92 Encouraging GPs to take up postgraduate dermatology degrees could improve competency.94-96 Furthermore, dermatological surgery is an area GPs could benefit from more training as specialist GPs had higher incomplete excision rates for skin cancer surgery than dermatologists.97 Final year medical students should be able to take a dermatology history, examine the skin, describe skin lesions, recognise cutaneous malignancies and know when to ask for help.93,98,99 A survey-based study of education methods and confidence levels found specialist clinical experiences and small-group learning increased confidence levels of medical students in dermatology.100 More dermatology teaching at undergraduate level is supported by an assessment of management of skin disease by Foundation Year 1 (FY1) doctors with respect to undergraduate dermatology experience.99,101,102 Longitudinal dermatology placements offer undergraduate experience in diagnosis and management that develops confidence for foundation practice.101 10 An audit of dermatological content of UK undergraduate curricula from medical schools against the recommendations for a core undergraduate dermatology curriculum published by the BAD, found evidence of good teaching on tumours, psoriasis and acne.98 Nevertheless, more assessments of dermatology knowledge in medical schools should be made to confirm students are fulfilling learning outcomes. Dermatology teaching needs to ensure opportunities for learning in the community are optimised by working with leads for primary care teaching.98 The audit found that not all curricula mentioned exploring a patient’s concerns, ‘describing skin lesions’ and recording findings accurately in patients’ notes.93,98 Clinical skills training and examination could incorporate more dermatology themes.93 To raise awareness, expert patients could help students understand the problems of living with chronic skin disease.98 Prosthetic melanomas could be a useful tool in assessing skin cancer detection skills.103 The audit found important topics such as meningococcaemia were omitted in some medical schools.98 Hence, efforts could be made to focus on a greater breadth of dermatology teaching.93,98 Dermatologists should be aware of the potential of the internet and social media as a source of public health information and teaching.104,105 Social media websites such as Facebook, Twitter and YouTube as well as Smartphone applications such as the BAD, Dermatology: Medical Student Edition or online resources including Dermatology handbook for Medical Students and Junior Doctors by the BAD have advantages of low cost, user interaction and rapid transmission of information to the wider community.105-112 However, 11 professional organisations such as the BAD must approve of content made available to the public so that information provided is reliable. The British Journal of Dermatology identified ‘ethnic skin’ as a the new era for studying human cutaneous diversity.113,114 Understanding human cutaneous diversity is important in cosmopolitan cities experiencing immigration.113 Dermatoses that may have been rare in practices are becoming more common.113 New combinations of ‘ethnic skin’ are born with new skin phenotypes and genotypes due to intermarriage.113 Focus should be placed on the subject of human cutaneous diversity to maintain high levels of skin care for future generations.113,114 Conclusion The question “how can we achieve ‘healthy skin for all’?” is challenging and involves principal focus on populations with greatest need for skin care. Continued research funding and collaboration is necessary, with improvements and assessments of dermatology training and treatments also essential. Nevertheless, more emphasis on prevention, self-management and primary care management may provide the greatest progress towards achieving this goal. Word Count: 2494 12 References 1.
