A randomised controlled trial of a community nursing intervention: improved quality of life and healing for clients with chronic leg ulcers

Interventions to Reduce Skin-related Self-stigma: A Systematic Review

Self-stigma beliefs are common among people with visible chronic skin diseases and can negatively affect their quality of life and psychosocial wellbeing. Hence, evidence-based interventions are urgently needed. The objective for this systematic review was to summarize research on available interventions and evaluate their benefits and limitations. Following PRISMA guidelines, we conducted an electronic database search of four databases (EMBASE, PsycINFO, PubMed, Web of Science). Studies were eligible if they (a) investigated interventions to reduce self-stigma in adults with chronic skin disease, (b) were original empirical articles, and (c) were written in English or German. Two independent reviewers conducted the abstract and full text screening as well as data extraction. The quality of the included studies was evaluated using the Critical Appraisal Skills Programme checklists. The initial search yielded 5811 abstracts; of which, 23 records were eligible. Studies addressed a broad range of skin conditions, and interventions ranged from social skills training, counselling and self-help to psychosocial and behavioural interventions. Overall, interventions had mostly positive effects on self-stigma and related constructs. However, the study quality was heterogeneous, and further efforts to develop, thoroughly evaluate and implement interventions tackling self-stigma in multiple skin conditions and languages are warranted.

The client and family experience of attending a nurse-led clinic for chronic wounds

BACKGROUND

The quality of life for individuals with chronic wounds is diminished due to poor health-related outcomes and the financial burden of wound care. The literature has shown nurse-led wound care to have a positive impact on wound healing and psychosocial wellbeing. However, there is minimal research investigating the lived experience of attending a nurse-led clinic for chronic wounds. The purpose of this study was to explore the client and family experience of attending a nurse-led clinic for chronic wounds.

METHODS

Qualitative descriptive study. Semi-structured telephone interviews were transcribed verbatim and thematic analysis was undertaken.

RESULTS

Twelve clients and two family members participated, and the average length of interviews was 20min. Three main themes emerged: (1) expecting and managing pain; (2) receiving expert advice and reflecting on previous care; and (3) managing the cost of care. There was an emphasis on the impact of chronic wounds on pain and the ability to complete the activities of daily living. Expert advice, client satisfaction and physical accessibility were highlighted as benefits of the clinic. Cost and minimal client education were identified as challenges of the clinic.

CONCLUSIONS

The findings demonstrated that chronic wounds have a significant impact on the client and family attending the nurse-led clinic. Comprehensive pain assessment, improved social support, better client education and cost-effective care is required to optimise the experience for people attending the nurse-led clinic.

The Lindsay Leg Club® Well Leg Regime: an evidence review

This article aims to review the scarce available evidence on the effectiveness of the Well Leg Programme within the Lindsay Leg Clubs in terms of preventing wound recurrence and improving members' wellbeing. It collates the numerical data on members' wounds and healing rates from the Lindsay Leg Club relational database and members' narratives from a qualitative service evaluation of the Lindsay Leg Clubs. Findings of the review suggest that remaining within the Well Leg regime for several months (or longer) after having had a healed ulcer seems to provide further opportunity to prevent recurrence, and may also provide non-clinical benefits, such as improved wellbeing. Based on the review of available published evidence into the effectiveness of the Well Leg regime, we conclude that there is scope for further studies, including a comparison with other existing treatment and prevention protocols.

Effect of educational interventions on wound healing in patients with venous leg ulceration: A systematic review and meta-analysis

Educational interventions for patients with venous leg ulceration (VLU) may promote adherence and self-management, however, their effect on wound healing is unclear. A systematic literature search was performed and randomised controlled trials with a focus on educational interventions were included. Wound healing was analysed by assessing wound healing rate, ulcer size, and the PUSH Score. Additional outcomes comprised pain, quality of life, and functional ability. The study protocol for this work is registered at PROSPERO 2020 (ID: CRD42021286152). Nine studies were included in this meta-analysis. The odds ratio for wound healing was 1.91 (95% CI, 0.99-3.67, P = .053) in favour of educational interventions compared to usual care. Ulcer size reduction was higher (MD: -7.22; 95% CI, -11.91 to -2.53, P = .003) in patients following educational interventions. Included studies also showed significant effects on pain, quality of life, and functional analysis, though no quantitative synthesis was feasible. The overall risk of bias showed some concerns. Educational interventions aim to actively involve patients in their treatment, thereby appearing to be able to have a positive impact on wound healing within 12 weeks. Consequently, integrating educational approaches to routine wound care may be a promising strategy to improve treatment of VLU.

Prospects for the application of home care in chronic wound management

With the aggravation of population aging, the number of patients with chronic diseases increases and public medical resources are increasingly strained. Home care allows patients to receive professional nursing services at home while achieving disease prevention, health promotion, and ease of public healthcare resources. Nowadays, home care services have been gradually applied and promoted in patients with chronic wounds. This article reviews the application effect of current home care services in the daily management of chronic wound patients and puts forward relevant suggestions.

Systematic review of adapted physical activity and therapeutic education of patients with chronic venous disease

BACKGROUND

Chronic venous disease (CVD), comprising impaired lower limb venous return, will lead to chronic distal venous pressure overload manifested by various clinical signs and symptoms and resulting in diminished quality of life. The CEAP (Clinical, Etiology, Anatomy, and Pathophysiology) classification of CVD distinguishes six stages (C0-C6) using clinical, etiologic, anatomic, and pathophysiologic parameters. In the present study, we analyzed the effects of adapted physical activity (APA) and patient-oriented therapeutic education (PTE) programs on the clinical signs, symptoms, and quality of life of patients with CVD.

METHODS

Our analysis, in accordance with the PRISMA (preferred reporting items for systematic reviews and meta-analyses) recommendations, included a search of PubMed, CINAHL and LiSSa databases, using a single search equation.

RESULTS

A total of 21 studies were selected for analysis. The analysis revealed first, that patients at stage C0 to C5 had had access to an APA program. This therapy alleviated the clinical signs and symptoms and improved the patients' quality of life. The beneficial effects of APA were greater in the programs that had included aquatic activities than in the program that were exclusively dry-land programs. Second, patients at stage C6 had predominantly followed a PTE program. This therapy showed beneficial effects on the clinical signs and symptoms. However, the quality of life had rarely been assessed.

CONCLUSIONS

At present, APA and PTE programs comprise useful and complementary therapeutic options for the care of patients with CVD. Two of the studies included in our review had evaluated the effects of combining these two approaches, notably in the context of balneotherapy, and reported promising results.

Potential predictors of quality of life in patients with venous leg ulcers: A cross-sectional study in Taiwan

Internationally, the impact of venous leg ulcers (VLUs) on the quality of life is well recognised; however, in Taiwan, the focus is only on chronic wound management. This cross‐sectional correlational study conducted at the cardiovascular and plastic surgery clinics of a regional teaching hospital between August 2019 and June 2020 investigates venous clinical severity, pain, fatigue, depression, sleep quality, quality of life, and related factors among 167 patients with VLUs. The potential predictors of the quality of life in terms of activities were venous clinical severity (P < 0.001), pain (P = 0.004), and fatigue (P < 0.001) after adjusting for covariates. The potential predictors of the quality of life in terms of the psychological domain were marital status (single/divorced) (P = 0.016), marital status (widowed) (P = 0.027), venous clinical severity (P < 0.001), pain (P = 0.001), and fatigue (P = 0.002). The potential predictors of the quality of life with regard to symptoms were venous clinical severity (P < 0.001), pain (P < 0.001), fatigue (P = 0.001), and depression (P = 0.038). These potential predictors can serve as the basis of interventions for patients with VLUs, such as those related to nutrition or training in wound dressing.

Social networks and their impact on access to health care: insights from older widows living alone in Kottayam, South India

The feminisation of ageing observed across the world is a significant challenge in many societies. Women's greater longevity is associated with the increased likelihood of age-related disability and morbidity. Furthermore, gendered disadvantage and poverty can make access to health care increasingly problematic in later years. Among the Indian states, Kerala has the highest number of residents above the age of 60 and many are older widows. Given this context, this paper explores what promotes access to health care for older widows living alone in the south Indian state of Kerala. Thirty-two in-depth interviews, eight focus group discussions and eight units of participant observation were carried out among widows, health-care providers and key informants. Applying a reflexive inductive approach to our analysis, the main barriers to access that emerged were altered family structures and loneliness, whilst enablers included good social networks and access to neighbourhood clinics. Our participants’ social networks were drawn from three levels: family, neighbourhood and the wider community. The ability to form a personal community from their social networks and the quality of relationships within this community strongly predicted the capacity to access health care. Efforts to improve access to health care for older widows requires a response that is rooted in the socio-cultural context of the community. Comprehensive social protection policies that promote initiatives to engender social capital among the older population, decentralised primary health-care services, and the training and sensitisation of health service staff would be key to promote equitable access for older widows.

Challenges of treating mixed arterial-venous disease of lower extremities

INTRODUCTION

Mixed arterial-venous lower extremity disease (AVLED) poses a unique challenge for clinicians. This review will outline the impact mixed AVLED has on patients and the healthcare system, by reviewing its epidemiology, diagnosis, current treatment, and the challenges encountered implementing therapies.

EVIDENCE ACQUISITION

An extensive search of current literature from online sources, journals and book chapters identified the current challenges facing the treatment of mixed arterial venous ulcers of the lower extremities and potential solutions to these challenges.

EVIDENCE SYNTHESIS

The challenges that are identified in the search are the time to heal AVLED, patient education and motivation, early detection of AVLED, wound care center development, treatment consensus from multidisciplinary team members, and cost of treatment.

CONCLUSIONS

AVLED ulcers are a challenging problem, but over time we have continued and will continue to improve patient care and tackle these difficult challenges as we have throughout the last century. A diagnostic algorithm to address how we approach these patients in terms of conservative care with wound care and compression and treat arterial and venous insufficiency is crucial. In looking to the future, continued standardization of wound care centers will overcome the social and financial challenges faced by patients and continued clinical research will improve targeted therapies and treatment challenges faced by physicians.

Patient education for preventing recurrence of venous leg ulcers: a systematic review

OBJECTIVE

To investigate the impact of patient education interventions on preventing the recurrence of venous leg ulcers (VLU).

METHOD

A systematic review was undertaken using the following databases: Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL; The Cochrane Library); Ovid; Ovid (In-process and Other Non-Indexed Citations); Ovid Embase and EBSCO CINAHL. Trial registries and reference lists of relevant publications for published and ongoing trials were also searched. There were no language or publication date restrictions. Randomised controlled trials (RCTs) and cluster RCTs of patient educational interventions for preventing VLU recurrence were included. Review authors working independently assessed trials for their appropriateness for inclusion and for their risk of bias, using pre-determined inclusion and quality criteria.

RESULTS

A total of four studies met the inclusion criteria (274 participants). Each trial explored different interventions as follows: the Lively legs programme; education delivered via a video compared with education delivered via a pamphlet; the Leg Ulcer Prevention Programme and the Lindsay Leg Club. Only one study reported the primary outcome of incidence of VLU recurrence. All studies reported at least one of the secondary outcomes: patient behaviours, patient knowledge and patient quality of life (QoL). It is uncertain whether patient education programmes make any difference to VLU recurrence at 18 months (risk ratio [RR]: 0.82; 95% confidence interval: [CI] 0.59 to 1.14) or to patient behaviours (walked at least 10 minutes/five days a week RR: 1.48; 95%CI: 0.99 to 2.21; walked at least 30 minutes/five days a week: RR 1.14; 95%CI: 0.66 to 1.98; performed leg exercises: RR: 1.47; 95%CI: 1.04 to 2.09); to knowledge scores (MD (mean difference) 5.12, 95% CI -1.54 to 11.78); or to QoL (MD: 0.85, 95% CI -0.13 to 1.83), as the certainty of evidence has been assessed as very low. It is also uncertain whether different types of education delivery make any difference to knowledge scores (MD: 12.40; 95%CI: -5.68 to 30.48). Overall, GRADE assessments of the evidence resulted predominantly in judgments of very low certainty. The studies were at high risk of bias and outcome measures were imprecise due to wide CIs and small sample sizes.

CONCLUSION

It is uncertain whether education makes any difference to the prevention of VLU recurrence. Therefore, further well-designed trials, addressing important clinical, QoL and economic outcomes are justified, based on the incidence of the problem and the high costs associated with VLU management.

Treatment with type-I collagen scaffolds in patients with venous ulcers. Case report

Introduction: Chronic venous insufficiency affects about 5% of the global adult population. Venous leg ulcers are one of the most frequent complications of this pathology, with a global prevalence of 2%. This disease affects both the quality of life of patients and, due to the high cost of the treatment, the health system. Compressive therapy and moist wound healing have been the gold standard treatment. However, when complications occur, they may not be effective.Case report: This is the case of a 66-year-old female patient with venous ulcers on her lower limbs and symptoms of fever and local pain that did not respond to conventional therapies. The patient was treated with a new dermal substitute made of an acellular type-I collagen membrane, which promotes the closure of the ulcer by stimulating the replacement of injured tissue with tissue similar to the healthy one. The condition of the patient improved at 16 weeks, and after 8 months of treatment there was no recurrence of the lesions.Conclusions: Acellular type-I collagen membrane developed by the Tissue Engineering Working Group of the Department of Pharmacy of the Universidad Nacional de Colombia is effective in treating venous ulcers of the lower limbs. Its low cost facilitates the access of the whole population to therapies based on its application.

Psychosocial factors of patients with venous leg ulcers and their association with healing

Objectives: To identify psychosocial factors present in patients with venous leg ulcers and the association that these factors have in the healing of venous leg ulcers. Methods: An integrative review of the quantitative studies in MEDLINE, Scielo and Cochrane Library databases, between 2008 and 2019, using the keywords, psychosocial factors, venous ulcer, wound healing, anxiety and depression in English, Spanish and Portuguese. Results: sixteen studies were included. The psychosocial factors present in patients with venous ulcers were depression, anxiety, feelings of helplessness, subjective well-being, self-esteem, loneliness and spirituality. Stress, a negative perception of venous ulcer, living alone and severe experience of symptoms such as pain and depression have statistically significant associations with longer periods of healing. Conclusions: Depression is one of the most frequently measured factors and present in this population. The available evidence on the association of psychosocial factors with the healing of venous ulcers is low.

Factores psicosociales en los pacientes con úlceras venosas y su asociación con la cicatrización

Objetivo: Identificar los factores psicosociales presentes en pacientes con úlceras venosas y la evidencia disponible sobre la asociación que estos factores tienen con la curación de este tipo de heridas. Métodos: Revisión integradora de la literatura de estudios cuantitativos en las bases de datos MEDLINE, Scielo y Cochrane Library entre los años 2008 y 2019, utilizando las palabras clave, factores psicosociales, úlcera venosa, cicatrización de heridas ansiedad y depresión en idioma inglés, español y portugués. Resultados: Dieciséis estudios fueron incluidos. Los factores psicosociales presentes en los pacientes con úlceras venosas fueron depresión, ansiedad, sentimientos de impotencia, bienestar subjetivo, autoestima, soledad y espiritualidad. El estrés, una percepción negativa de la úlcera venosa, vivir solo y la experiencia severa de síntomas como dolor y depresión tienen asociaciones estadísticamente significativas con periodos más prolongados de curación. Conclusión: La depresión es uno de los factores psicológicos medido y presente con mayor frecuencia en esta población. La evidencia disponible frente a la asociación de los factores psicosociales con la curación de úlceras venosas es escasa.

Influence of peer-based rehabilitation interventions for improving mobility and participation among adults with mobility disabilities: a systematic review

Purpose: The prevalence of mobility disability reaches up to 20.5% among older adults. Mobility is a key factor of participation, thus rehabilitation interventions often aim to improve mobility and participation. Peer-based approaches to intervention delivery have become increasingly common. This study aims to identify peer-based rehabilitation interventions and summarize their influence on mobility and participation among individuals with mobility disabilities.Method: A systematic review was conducted using CINALH, EMBASE, MEDLINE, and PsycINFO. Articles that evaluated peer-based rehabilitation interventions for individuals with a mobility disability and assessed mobility or participation, as defined in the International Classification of Functioning, Disability and Health framework, were included. Study quality was assessed using the Physical Therapy Evidence Database and the Quality Assessment Tool for Before-After Studies With No Control Group.Results: Thirteen peer-based studies were identified. Six peer-led studies evaluated participation and two evaluated mobility. Seven professional-led studies evaluated participation and six evaluated mobility. Randomized controlled trials had fair to high quality. The quality of pre-post studies ranged from poor to good.Conclusion: Peer-based interventions should not be overlooked as a potential intervention strategy, but further research is needed to establish their influence on mobility and participation.Implications for rehabilitationPeers offer a unique model of intervention that could support clinicians in their effort to improve mobility and participation outcomes for individuals with disabilities.There are currently two main models of peer-based interventions in rehabilitation: professional-led (peers assist professionals to facilitate the intervention) and peer-led interventions (peers facilitate the intervention).Both professional-led and peer-led models of intervention could be helpful in facilitating participation and in increasing mobility.

Quality indicators for a community-based wound care centre: An integrative review

The purpose of this review was to identify the role and contribution of community-based nurse-led wound care as a service delivery model. Centres increasingly respond proactively to assess and manage wounds at all stages - not only chronic wound care. We conducted an integrative review of literature, searching five databases, 2007-2018. Based on inclusion and exclusion criteria, we systematically approached article selection and all three authors collaborated to chart the study variables, evaluate data, and synthesise results. Eighteen studies were included, representing a range of care models internationally. The findings showed a need for nurse-led clinics to provide evidence-based care using best practice guidelines for all wound types. Wound care practices should be standardised across the particular service and be integrated with higher levels of resources such as investigative services and surgical units. A multi-disciplinary approach was likely to achieve better patient outcomes, while patient-centred care with strong patient engagement was likely to assist patients' compliance with treatment. High-quality community-based wound services should include nursing leadership based on a hub-and-spoke model. This is ideally patient-centred, evidence-based, and underpinned by a commitment to developing innovations in terms of treatment modalities, accessibility, and patient engagement.

The outcomes and experience of people receiving community-based nurse-led wound care: A systematic review

AIMS AND OBJECTIVES

To review the literature related to the outcomes and experience of people receiving nurse-led care for chronic wounds in the community.

BACKGROUND

Chronic wounds lead to a poor quality of life and are an economic burden to the Australian healthcare system. A lack of awareness into the significance of chronic wounds leads to limited resources being available to facilitate the provision of evidence-based care. The majority of chronic wounds are managed by nurses in the community, and a better understanding into current models of care is required to inform future practice.

DESIGN

A systematic quantitative literature review.

METHODS

A systematic search was conducted in four electronic databases, and the inclusion criteria were as follows: English language, peer-reviewed, published from 2009-2019 and primary research. The data were compiled into an Excel database for reporting as per the Pickering and Byrne (Higher Education Research & Development, 33, 534.) method of systematic quantitative literature review. This review used the PRISMA checklist. The Mixed Methods Appraisal Tool was used for quality appraisal.

RESULTS

Twelve studies were included in the review. Home nursing care, social community care and nursing within a wound clinic were identified as three types of nurse-led care in the literature. The findings demonstrate that nurse-led care was cost-effective, reported high levels of client satisfaction and contributed to improved wound healing and reduced levels of pain.

CONCLUSIONS

Nurse-led care is a positive experience for people with chronic wounds and leads to better outcomes. The findings suggested a need for further client education and specialised training for healthcare practitioners managing chronic wounds.

RELEVANCE TO CLINICAL PRACTICE

This review demonstrates that nurse-led care for people with chronic wounds in the community is cost-effective and improves client outcomes. Raising awareness into the significance of chronic wounds aims to promote the resources required to facilitate evidence-based care.

Nursing Interventions Aimed at Persons with Venous Ulcers: an Integrative Review

Objectives: This work sought to identify and describe the theoretical foundations, components, duration, delivery mode, and results of the nursing interventions aimed at persons with venous ulcers as available in the literature. Materials and method: Integrative review between 2000 and 2018 in the Pubmed, Ovidnursing, and EBSCOhost electronic databases. Results: This review includes 16 articles. Most of the interventions were of educational nature; three were developed in the community (through the Leg Club model) and the other ones were delivered by a nursing professional, face to face. The minimum time of duration for these was eight weeks, with telephone follow up. The most-common result variables were venous ulcer healing and reduction of the wound area. Conclusions: Diversity existed in relation with the components of the interventions and the results expected. Report of the interventions must be reinforced, along with the use of nursing theories that support their design.

The lived experience of recurrence prevention in patients with venous leg ulcers: An interpretative phenomenological study

AIM OF THE STUDY

To explore patient understanding of why they develop a venous leg ulcer and how they can prevent recurrence.

METHOD

The methodological framework of the hermeneutic phenomenological approach was used. Semi-structured interviews were conducted with seventeen participants living with a venous leg ulcer from May 2017 to November 2018. Data were analysed using Smith's interpretative hermeneutic analysis.

RESULTS

The results are categorised into three main themes: "Trauma due to accident" (initial venous leg ulcer) and "Prevention of ulcer recurrence" (compression); "Trauma due to compression therapy" (venous leg ulcer recurrence). The findings demonstrate active venous leg ulcers are often caused by acute incidents while carrying out an activity in people with underlying chronic venous insufficiency. After a complete healing, preventive measures, such a compression stockings are initiated by the patient or health care provider. Trauma due to adherence to compression stockings caused skin breakdown beneath compression that caused subsequent ulcer recurrence.

CONCLUSION

This study contributes to understanding the lived experience of patients with venous leg ulcers who develop a venous leg ulcer and their understanding of how they can prevent recurrence. Patients with VLUs would benefit from early preventive strategies, such as such a compression stockings fitting and application, integrated into daily care plan of primary care and community settings.

Pain in persons with chronic venous leg ulcers: A systematic review and meta-analysis

Pain is a serious problem for patients with leg ulcers. Research mainly focuses on dressing‐related pain; however, chronic background pain may be just as devastating. Our main objective was to describe the prevalence and characteristics of wound‐related background pain in persons with chronic venous leg ulcers. We performed a systematic review to synthesise data from quantitative studies. Studies were eligible if they reported original baseline‐ or cross‐sectional data on background pain in chronic venous leg ulcers. The initial search identified 2454 publications. We included 36 descriptive and effect studies. The pooled prevalence of wound‐related background pain (from 10 studies) was 80% (95% CI 65‐92%). The mean pain intensity score (from 27 studies) was 4 (0‐10 numeric rating scale) (95% CI 3.4‐4.5). Other pain characteristics could not be synthesised. We identified few sufficiently high‐quality studies on prevalence and intensity of wound‐related background pain in patients with chronic venous leg ulcers. Four of five persons experience mild to moderate pain. Because of poor quality of pain assessment and report, we believe that the available research does not provide a sufficiently nuanced understanding of background pain in this patient group.

Research on a physical activity tracking system based upon three-axis accelerometer for patients with leg ulcers

Venous leg ulcerations are a common problem, with high prevalence in the middle-aged and elderly population, and more attention on research of their physical activities has been paid, as they have great effects on the blood circulation of the lower limb. With enough, appropriate training, the chronic venous ulcerations in the lower limb can be avoided and alleviated, and venous hypertension can be reduced effectively. The study deals with a physical activity tracking system for the patients based on a three-axis accelerometer. The system uses a three-axis accelerometer, a microcontroller, and a wireless Bluetooth module to form a data acquisition platform to acquire accelerations of the lower limb movement, and sends it to a smart mobile phone via the wireless Bluetooth module. The system takes advantages of the smart mobile phone to guide the chronic venous leg ulcers to do prescribed rehabilitation exercises for the lower limb muscles, perform acceleration data preprocessing, wavelet transform and reconstruction, denoising and feature extraction, obtain the results of the rehabilitation exercises, and then give reasonable evaluation and judgment. It is helpful to treat underlying venous reflux, create such an environment that allows skin to grow across an ulcer, and accelerate ulcer healing process consequently.

Peripheral arterial disease screening and diagnostic practice: A scoping review

Early reliable, valid screening, diagnosis, and treatment improve peripheral arterial disease outcomes, yet screening and diagnostic practices vary across settings and specialties. A scoping literature review described reliability and validity of peripheral ischaemia diagnosis or screening tools. Clinical studies in the PUBMED database January 1, 1970, to August 13, 2018, were reviewed summarising ranges of reliability and validity of peripheral ischaemia diagnostic and screening tools for patients with non-neuropathic lower leg ischaemia. Peripheral ischaemia screening and diagnostic practices varied in parameters measured such as timing, frequency, setting, ordering clinicians, degree of invasiveness, costs, definitions, and cut-off points informing clinical and referral decisions. Traditional ankle/brachial systolic blood pressure index <0.9 was a reliable, valid lower leg ischaemia screening test to trigger specialist referral for detailed diagnosis. For patients with advanced peripheral ischaemia or calcified arteries, toe-brachial index, claudication, or invasive angiographic imaging techniques that can have complications were reliable, valid screening, and diagnostic tools to inform management decisions. Ankle/brachial index testing is sufficiently reliable and valid for use during routine examinations to improve timing and consistency of peripheral ischaemia screening, triggering prompt specialist referral for more reliable, accurate Doppler, or other diagnosis to inform treatment decisions.

Construção e validação de um folheto educativo para tratamento de úlcera venosa

Adjuvant therapies in venous leg ulcer management: A scoping review

Compression therapy is the current evidence-based approach to manage venous leg ulcers (VLU); however, adherence is a major barrier to successful treatment. Combination approaches may relieve the burden of treatment by shortening the time to ulcer healing. This scoping review conducted by Australian researchers aimed to establish the evidence of effectiveness of various adjuvant methods on wound healing and recurrence. Randomized Controlled Trials (RCTs), and Systematic Reviews (SR) and Meta-Analyses (MA) on VLU management approaches published from January 2015 to December 2018 were included in this review. The articles included in the scoping review were grouped according to the management approaches, including (1) pharmaceutical interventions, (2) surgical interventions, (3) topical agents, (4) the use of devices, and (5) other, such as physiotherapy and psychological interventions. Results of this scoping review indicate that there is a limited high-quality evidence of effectiveness in most adjuvant therapies on wound healing and recurrence. Given the low-quality evidence observed in this scoping review for adjuvant treatments, the implication for practice is that current management guidelines be followed. Further rigorous studies have the potential to produce better quality evidence. Quality of evidence can be improved by ensuring large sample sizes of a single etiology wounds, standardizing reporting outcomes, and maintaining detailed and evidence-based protocols in physiological or psychological interventions.

Implementation of the Champions for Skin Integrity model to improve leg and foot ulcer care in the primary healthcare setting

AIMS

To facilitate evidence-based leg and foot ulcer management through implementation of the Champions for Skin Integrity model to education in primary health care in Australia.

BACKGROUND

Leg and foot ulcers are frequently seen wounds in general practice and wound care the most frequently performed activity by practice nurses. The literature reports the lack of evidence-based leg and foot ulcer assessment, management and prevention strategies in this setting, and previous research in regard to confidence and knowledge has indicated that general practice health professionals have the greatest need for education in wound care.

DESIGN

Pre-post, nonequivalent group research design.

METHODS

The Champions for Skin Integrity model of evidence-based wound management utilised strategies including workshops, development of Champions and use of resources. Pre- and post-implementation health professional surveys and patient clinical audits were completed. Descriptive statistics were calculated for all variables. Paired t tests identified statistically significant differences between the pre/post staff survey data. STROBE guidelines for reporting were followed (See Appendix S1).

RESULTS

One hundred nine general practice healthcare professional staff attended the workshops. Significant outcomes were noted in increased levels of confidence in ability to assess, manage and prevent all types of leg and foot ulcers, as well as to apply evidence-based practice and change management following workshops. Pre- and post-skin audits also indicated an increase in evidence-based practices.

CONCLUSION

Implementation of Champions for Skin Integrity strategies in this sample of primary healthcare professionals in general practice fostered a positive change in evidence-based wound management, assessment and prevention.

RELEVANCE TO CLINICAL PRACTICE

The Champions for Skin Integrity model has supported increases in evidence-based practices in treatment and management of wounds in primary healthcare professionals, similar to the positive outcomes gained in the aged care setting. This is likely to lead to positive outcomes for those with wounds in this setting.

In situ gelation of rhEGF-containing liquid crystalline precursor with good cargo stability and system mechanical properties: a novel delivery system for chronic wounds treatment

The objective of this study was to develop a novel delivery system for recombinant human epidermal growth factor (rhEGF) for chronic wound treatment. Such a delivery system should be of good cargo stability and system mechanical properties in order to guarantee a satisfactory wound-healing effect. rhEGF-containing lyotropic liquid crystalline precursors (rhEGF-LLCPs) with in situ gelation capability were considered as a promising candidate to achieve this aim. Various properties of the optimal formulations (rhEGF-LLCP1 and rhEGF-LLCP2) were characterized, including apparent viscosity, gelation time, in vitro release and phase behavior. The stability of rhEGF and system mechanical properties (i.e. mechanical rigidity and bioadhesive force) were verified. Interestingly, rhEGF-LLCP2 with a larger internal water channel diameter exhibited faster release rate in vitro and then better bioactivity in Balb/c 3T3 and HaCaT cell models. Moreover, rhEGF-LLCP2 showed distinct promotion effects on wound closure, inflammatory recovery and re-epithelization process in Sprague-Dawley rat models. In conclusion, rhEGF-LLCP emerged as a prospective candidate to preserve the stability and enhance the wound-healing effect of rhEGF, which might serve as a new delivery system for chronic wound therapies.

Chronic wounds in Australia: A systematic review of key epidemiological and clinical parameters

Chronic wounds are a significant problem in Australia. The health care-related costs of chronic wounds in Australia are considerable, equivalent to more than AUD $3.5 billion, approximately 2% of national health care expenditure. Chronic wounds can also have a significant negative impact on the health-related quality of life of affected individuals. Studies have demonstrated that evidence-based care for chronic wounds improves clinical outcomes. Decision analytical modelling is important in confirming and applying these findings in the Australian context. Epidemiological and clinical data on chronic wounds are required to populate decision analytical models. Although epidemiological and clinical data on chronic wounds in Australia are available, these data have yet to be systematically summarised. To address these omissions and clarify the state of existing evidence, we conducted a systematic review of the literature on key epidemiological and clinical parameters of chronic wounds in Australia. A total of 90 studies were selected for inclusion. This paper presents a synthesis of the evidence on the prevalence and incidence of chronic wounds in Australia, as well as rates of infection, hospitalisation, amputation, healing, and recurrence.

Patient experiences of living with chronic leg ulcers and making the decision to seek professional health-care

OBJECTIVE:

The aim of the study was to elucidate how patients experience living with chronic leg ulcers before consulting a health professional, and to determine the reasons behind the decision to visit a health-care centre.

METHOD:

A qualitative interview study was carried out. There were 11 participants, five men and six women (age range: 27-83 years old). All participants in the study were patients visiting the public primary medical centre in western Sweden for the first time for a chronic leg ulcer. The data was obtained by recorded interviews. Systematic text condensation (STC) by Malterud was applied to the analysis.

RESULTS:

The analysis identified five main categories of the issues relating to ulcers to their ulcers: convictions, pain, emotions, strategies, and health-care treatment. At first, patients accepted the inconvenience of a leg ulcer. Gradually, they focused more on strategies dealing with the ulcer, and withdrew from their social context, while their fears increased. Many needed support in the decision to seek professional care.

CONCLUSION:

Despite pain, anxiety, emotional lability, and disappointment, they had strategies to cope with ulcers on their own. A social network seems crucial for the decision to seek professional health care and greater knowledge of leg ulcers, particularly in the elderly population, is needed.

Effectiveness of the strategies of an orientation programme for the lifestyle and wound-healing process in patients with venous ulcer: A randomised controlled trial

This study aimed to evaluate the effect of strategies of a lifestyle orientation programme on patients with venous ulcer in elastic compression therapy. This was a single-blind, 2-arm, randomised clinical controlled trial. The primary outcome included the reduction of the wound surface area. The secondary outcomes included the perception of pain, questionnaire of ulcer status, and quality of life. Seventy-one patients with ulcers of venous aetiology were randomised into 2 arms: control group (CG) and intervention group (IG), with a 12-week follow up. The CG was provided with the routine guidelines of the health services. Meanwhile, the IG was provided with lifestyle guidelines regarding the physiopathology of a venous ulcer, importance of compression therapy, physical exercises and rest in 4 face-to-face and 2 telephone interviews. The IG had significant improvement on the wound healing on 30, 60, and 90 days of follow up when compared with the CG (P = .0197; P = .0472; P = .0116). There were no statistical differences between groups; both had improvement in the quality of life and pain perception. Our results demonstrated that elastic compression therapy along with guidelines on lifestyle is effective adjunctive treatment to promote wound healing in patients with leg ulcers.

Management of Patients With Venous Leg Ulcers: Challenges and Current Best Practice

Introduction It is well documented that the prevalence of venous leg ulcers (VLUs) is increasing, coinciding with an ageing population. Accurate global prevalence of VLUs is difficult to estimate due to the range of methodologies used in studies and accuracy of reporting. (1) Venous ulceration is the most common type of leg ulceration and a significant clinical problem, affecting approximately 1% of the population and 3% of people over 80 years of age (2) in westernised countries. Moreover, the global prevalence of VLUs is predicted to escalate dramatically, as people are living longer, often with multiple comorbidities. Recent figures on the prevalence of VLUs are based on a small number of studies, conducted in Western countries, and the evidence is weak. However, it is estimated that 93% of VLUs will heal in 12 months, and 7% remain unhealed after five years. (3) Furthermore, the recurrence rate within 3 months after wound closure is as high as 70%. (4) (-6) Thus, cost-effective adjunct evidence-based treatment strategies and services are needed to help prevent these ulcers, facilitate healing when they occur and prevent recurrence. The impact of a VLU represents social, personal, financial and psychological costs on the individual and further economic drain on the health-care system. This brings the challenge of providing a standardised leg ulcer service which delivers evidence-based treatment for the patient and their ulcer. It is recognised there are variations in practice and barriers preventing the implementation of best practice. There are patients not receiving appropriate and timely treatment in the initial development of VLUs, effective management of their VLU and preventing recurrence once the VLU has healed. Health-care professionals (HCPs) and organisations must have confidence in the development process of clinical practice guidelines and have ownership of these guidelines to ensure those of the highest quality guide their practice. These systematic judgments can assist in policy development, and decision making, improve communication, reduce errors and improve patient outcomes. There is an abundance of studies and guidelines that are available and regularly updated, however, there is still variation in the quality of the services offered to patients with a VLU. There are also variations in the evidence and some recommendations contradict each other, which can cause confusion and be a barrier to implementation. (7) The difference in health-care organisational structures, management support and the responsibility of VLU management can vary in different countries, often causing confusion and a barrier to seeking treatment. These factors further complicate the guideline implementation process, which is generally known to be a challenge with many diseases. (8).

A systematic review of community Leg Clubs for patients with chronic leg ulcers

Aim

Appraise the evidence on the outcomes of Leg Clubs on ulcer healing, psychosocial outcomes, patient safety, cost and experiences of Leg Club members.

Background

The Leg Club is a community-based social model of care in 30 UK locations and nine overseas for treating patients with chronic leg wounds. However, its cumulative effectiveness has not been reviewed to-date.

Methods

Systematic review of primary research relating to the impact and quality of care of Leg Clubs treating patients with leg ulcers. Six electronic databases were systematically searched using the MeSH term ‘leg ulcer’, including other representative terms, in combination with ‘Leg Club’. The quality of individual studies was assessed using appraisal tools. The confidence in the quantitative evidence was evaluated using Grading of Recommendations Assessment, Development and Evaluation (GRADE); and the Confidence in the Evidence from Reviews of Qualitative Research (CERQual) assessed the quality of qualitative findings.

Findings

A total of 17 relevant publications were identified. Out of the 17 articles, four publications represent findings from randomised controlled trial (RCT). Thus, evidence from 14 independent studies involving at least 532 participants were included in the synthesis of this review. The quality of the evidence varied across the different outcomes and were mostly low or of very low quality. Findings from one underpowered RCT from Australia reporting on clinical, patient-reported outcomes and economic outcomes were evaluated as moderate quality. Studies indicate that the Leg Club model has a positive impact on ulcer healing and recurrence, mood, sleep, quality of life and pain. Moreover, only three studies assessed wound infections and reported no infections had occurred during treatment at the Leg Clubs. Economic evaluations find Leg Clubs to be probably more cost-effective than usual care. Both patients and nurses projected positive views about the Leg Clubs, with particular emphasis on improved social interactions and delivery of patient-centred care.

The effects of psychological interventions on wound healing: A systematic review of randomized trials

PURPOSE

Psychological stress has been shown to delay wound healing. Several trials have investigated whether psychological interventions can improve wound healing, but to date, this evidence base has not been systematically synthesized. The objective was to conduct a systematic review of randomized controlled trials in humans investigating whether psychological interventions can enhance wound healing.

METHODS

A systematic review was performed using PsychINFO, CINAHL, Web of Science, and MEDLINE. The searches included all papers published in English up until September 2016. The reference lists of relevant papers were screened manually to identify further review articles or relevant studies. Nineteen studies met inclusion criteria and were included in the review.

RESULTS

Fifteen of nineteen studies were of high methodological quality. Six studies were conducted with acute experimentally created wounds, five studies with surgical patients, two studies with burn wounds, two studies with fracture wounds, and four studies were conducted with ulcer wounds. Post-intervention standardized mean differences (SMD) between groups across all intervention types ranged from 0.13 to 3.21, favouring improved healing, particularly for surgical patients and for relaxation interventions. However, there was some evidence for publication bias suggesting negative studies may not have been reported. Due to the heterogeneity of wound types, population types, and intervention types, it is difficult to pool effect sizes across studies.

CONCLUSIONS

Current evidence suggests that psychological interventions may aid wound healing. Although promising, more research is needed to assess the efficacy of each intervention on different wound types. Statement of contribution What is already known on this subject? Psychological stress negatively affects wound healing. A number of studies have investigated whether psychological interventions can improve healing. However, no systematic reviews have been conducted. What does this study add? Synthesis and review of 19 trials conducted on psychological interventions and wound healing. Most evidence supports improved healing, particularly for surgical wounds and relaxation interventions. More research is needed on different intervention types with clinical wounds and into mechanisms of action.

Distinct Wound Healing and Quality-of-Life Outcomes in Subgroups of Patients With Venous Leg Ulcers With Different Symptom Cluster Experiences

CONTEXT

Adults with venous leg ulcers frequently experience multiple symptoms that may influence quality of life (QOL).

OBJECTIVES

The objective of this study was to identify patient subgroups based on their experience with a pain-depression-fatigue-sleep disturbance symptom cluster and to identify differences in patient characteristics and wound-healing and QOL outcomes between the subgroups.

METHODS

Secondary data analysis from previous longitudinal studies of 247 patients with venous leg ulcers. Latent class analysis identified subgroups of patients with distinct experiences with the symptom cluster of pain, depression, fatigue, and sleep disturbance. Hierarchical regression analysis identified relationships between the subgroups and QOL outcomes. Survival analysis identified differences between the subgroups and ulcer healing.

RESULTS

Latent class analysis found 67% of patients were in a mild symptom subgroup (i.e., experiencing no or mild pain, depressive symptoms, fatigue, or sleep disturbance). One-third of the samples were in a severe symptom subgroup, who reported moderate-to-severe levels of these symptoms. Compared with the mild subgroup, patients in the severe subgroup had poorer QOL scores (t = 8.06, P < 0.001). Symptom subgroup membership accounted for 19% of the variance (P < 0.001) within a hierarchical regression model that explained 42% of the variance in QOL (F(7,170) = 16.89, P < 0.001, R² = 0.42). Cox proportional hazards regression found that at enrollment into the study, patients in the severe symptom subgroup were 1.5 times (95% confidence interval 1.02-2.08) less likely to heal in the following 24 weeks (P = 0.037).

CONCLUSION

Significant relationships were found between delayed ulcer healing, decreased QOL, and membership in the severe symptom subgroup. These findings suggest that comprehensive symptom assessment is needed to identify patients at higher risk for poor outcomes and enable early intervention.

Reduced prevalence and severity of wounds following implementation of the Champions for Skin Integrity model to facilitate uptake of evidence-based practice in aged care

AIMS AND OBJECTIVES

To evaluate the implementation of the Champions for Skin Integrity model on facilitating uptake of evidence-based wound management and improving skin integrity in residents of aged care facilities.

BACKGROUND

The incidence of skin tears, pressure injuries and leg ulcers increases with age, and such wounds can be a serious issue in aged care facilities. Older adults are not only at higher risk for wounds related to chronic disease but also injuries related to falls and manual handling requirements.

DESIGN

A longitudinal, pre-post design.

METHODS

The Champions for Skin Integrity model was developed using evidence-based strategies for transfer of evidence into practice. Data were collected before and six months after implementation of the model. Data on wound management and skin integrity were obtained from two random samples of residents (n = 200 pre; n = 201 post) from seven aged care facilities. A staff survey was also undertaken (n = 126 pre; n = 143 post) of experience, knowledge and evidence-based wound management. Descriptive statistics were calculated for all variables. Where relevant, chi-square for independence or t-tests were used to identify differences between the pre-/postdata.

RESULTS

There was a significant decrease in the number of residents with a wound of any type (54% pre vs 43% post, χ² 4·2, p = 0·041), as well as a significant reduction in specific wound types, for example pressure injuries (24% pre vs 10% post, χ² 14·1, p < 0·001), following implementation of the model. An increase in implementation of evidence-based wound management and prevention strategies was observed in the postimplementation sample in comparison with the preimplementation sample. This included use of limb protectors and/or protective clothing 6% pre vs 20% post (χ² 17·0, p < 0·001) and use of an emollient or soap alternative for bathing residents (50% pre vs 74% post, χ² 13·9, p = 0·001).

CONCLUSIONS

Implementation of the model in this sample fostered an increase in implementation of evidence-based wound management and prevention strategies, which was associated with a decrease in the prevalence and severity of wounds.

RELEVANCE TO CLINICAL PRACTICE

This study suggests the Champions for Skin Integrity model has the potential to improve uptake of evidence-based wound management and improve skin integrity for older adults.

Ulcer area reduction at 2 weeks predicts failure to heal by 24 weeks in the venous leg ulcers of patients living alone

OBJECTIVE

Chronic wounds are costly and affect approximately 1-2% of the population. Venous disease is responsible for about 60% of all chronic leg ulcers and these ulcers can be debilitating, with evidence of a decreased quality of life. Unfortunately, up to 30% of venous leg ulcers (VLUs) fail to heal, despite best practice treatment. This study aimed to identify risk factors associated with delayed healing in participants with VLUs and in particular, whether psychosocial factors play a part in this process.

METHOD

A secondary analysis was conducted of a large data set of clinical, wound healing, health, social, economic and psychological data collected in previous prospective studies of participants with VLUs. Generalised linear mixed modelling was used to identify independent predictors of failure to heal after 24 weeks.

RESULTS

We recruited 247 participants with 318 VLUs from hospital and community settings. Findings revealed that four early predictors were independently significantly associated with failure to heal by 24 weeks. These were: participants who lived alone (OR 2.3, 95%CI [1.13-4.61], p=0.03); had less than 25% reduction in ulcer area within two weeks of treatment (OR 10.07, 95%CI [4.60-22.19], p<0.001); had higher ulcer severity scores (OR 5.1, 95%CI [2.33-11.88], p=0.001); and participants who were not treated with high level compression therapy (i.e.>30 mmHg) at the time of assessment (OR 4.18, 95% CI [1.95-8.97], p=0.002).

CONCLUSION

Identified risk factors offer an opportunity for clinicians to determine realistic outcomes for their patients and to guide decisions on early referral and implementation of tailored adjunctive interventions. Additionally, findings from this study suggest health professionals need to assess and address not only clinical risk factors but also social risk factors, when planning interventions to promote healing.

Improving the self-management of chronic pain: COping with persistent Pain, Effectiveness Research in Self-management (COPERS)

Background

Chronic musculoskeletal pain is a common problem that is difficult to treat. Self-management support interventions may help people to manage this condition better; however, there is limited evidence showing that they improve clinical outcomes. Our overarching research question was ‘Does a self-management support programme improve outcomes for people living with chronic musculoskeletal pain?’.

Aim

To develop, evaluate and test the clinical effectiveness and cost-effectiveness of a theoretically grounded self-management support intervention for people living with chronic musculoskeletal pain.

Methods

In phase 1 we carried out two systematic reviews to synthesise the evidence base for self-management course content and delivery styles likely to help those with chronic pain. We also considered the psychological theories that might underpin behaviour change and pain management principles. Informed by these data we developed the Coping with persistent Pain, Evaluation Research in Self-management (COPERS) intervention, a group intervention delivered over 3 days with a top-up session after 2 weeks. It was led by two trained facilitators: a health-care professional and a layperson with experience of chronic pain. To ensure that we measured the most appropriate outcomes we reviewed the literature on potential outcome domains and measures and consulted widely with patients, tutors and experts. In a feasibility study we demonstrated that we could deliver the COPERS intervention in English and, to increase the generalisability of our findings, also in Sylheti for the Bangladeshi community. In phase 2 we ran a randomised controlled trial to test the clinical effectiveness and cost-effectiveness of adding the COPERS intervention to a best usual care package (usual care plus a relaxation CD and a pain toolkit leaflet). We recruited adults with chronic musculoskeletal pain largely from primary care and musculoskeletal physiotherapy services in two localities: east London and Coventry/Warwickshire. We collected follow-up data at 12 weeks (self-efficacy only) and 6 and 12 months. Our primary outcome was pain-related disability (Chronic Pain Grade disability subscale) at 12 months. We also measured costs, health utility (European Quality of Life-5 Dimensions), anxiety, depression [Hospital Anxiety and Depression Scale (HADS)], coping, pain acceptance and social integration. Data on the use of NHS services by participants were extracted from NHS electronic records.

Results

We recruited 703 participants with a mean age of 60 years (range 19–94 years); 81% were white and 67% were female. Depression and anxiety symptoms were common, with mean HADS depression and anxiety scores of 7.4 [standard deviation (SD) 4.1] and 9.2 (SD 4.6), respectively. Intervention participants received 85% of the course content. At 12 months there was no difference between treatment groups in our primary outcome of pain-related disability [difference –1.0 intervention vs. control, 95% confidence interval (CI) –4.9 to 3.0]. However, self-efficacy, anxiety, depression, pain acceptance and social integration all improved more in the intervention group at 6 months. At 1 year these differences remained for depression (–0.7, 95% CI –1.2 to –0.2) and social integration (0.8, 95% CI, 0.4 to 1.2). The COPERS intervention had a high probability (87%) of being cost-effective compared with usual care at a threshold of £30,000 per quality-adjusted life-year.

Conclusions

Although the COPERS intervention did not affect our primary outcome of pain-related disability, it improved psychological well-being and is likely to be cost-effective according to current National Institute for Health and Care Excellence criteria. The COPERS intervention could be used as a substitute for less well-evidenced (and more expensive) pain self-management programmes. Effective interventions to improve hard outcomes in chronic pain patients, such as disability, are still needed.

Difficult-to-heal wounds of mixed arterial/venous and venous etiology: a cost-effectiveness analysis of extracellular matrix

Importance

Difficult-to-heal wounds pose clinical and economic challenges, and cost-effective treatment options are needed.

Objective

The aim of this study is to determine the cost-effectiveness of extracellular matrix (ECM) relative to standard of care (SC) on wound closure for the treatment of mixed arterial/venous (A/V) or venous leg ulcers (VLUs).

Design, setting, and participants

A two-stage Markov model was used to predict the expected costs and outcomes of wound closure for ECM and SC. Outcome data used in the analysis were taken from an 8-week randomized clinical trial that directly compared ECM and SC. Patients were followed up for an additional 6 months to assess wound closure. Forty-eight patients completed the study; 25 for ECM and 23 for SC. SC was defined as a standard moist wound dressing. Transition probabilities for the Markov states were estimated from the clinical trial.

Main outcomes and measures

The economic outcome of interest was direct cost per closed-wound week. Resource utilization was based on the treatment regimen used in the clinical trial. Costs were derived from standard cost references. The payer’s perspective was taken.

Results

ECM-treated wounds closed, on average, after 5.4 weeks of treatment, compared with 8.3 weeks for SC wounds (P=0.02). Furthermore, complete wound closure was significantly higher in patients treated with ECM (P<0.05), with 20 wounds closed in the ECM group (80%) and 15 wounds closed in the SC group (65%). After 8 months, patients treated with ECM had substantially higher closed-wound weeks compared with SC (26.0 weeks versus 22.0 weeks, respectively). Expected direct costs per patient were $2,527 for ECM and $2,540 for SC (a cost savings of $13).

Conclusion and relevance

ECM yielded better clinical outcomes at a slightly lower cost in patients with mixed A/V and VLUs. ECM is an effective treatment for wound healing and should be considered for use in the management of mixed A/V and VLUs.

[People with vascular ulcers in outpatient nursing care: a study of sociodemographic and clinical variables]

The aim of this study was to analyze the sociodemographic and clinical characteristics of people with vascular ulcers and to investigate the association between these variables. This cross-sectional, observational clinical study was conducted in outpatient clinics from February to August 2009. Interview, clinical exam, Pressure Ulcer Scale Healing and photographic registry of the wounds were performed. Forty-two individuals participated who were, on average, 60 (± 12) years old, 73.8% males, with single wounds (66.7%) resulting from alterations in venous circulation (90.5%). Their wounds had lasted for up to one year (55.5%). There was an association between the PUSH score (p=0.019) and depth of wound (p=0.027) with currently performing occupational activity, as well as between history of tobacco use and gender (p=0.049). The sociodemographic characteristics that were observed were similar to the others, except for being male, which indicates the need for more studies in the population in Goiânia, Brazil.

Interventions for helping people adhere to compression treatments for venous leg ulceration

BACKGROUND

Chronic venous ulcer healing is a complex clinical problem that requires intervention from skilled, costly, multidisciplinary wound-care teams. Compression therapy has been shown to help heal venous ulcers and to reduce recurrence. It is not known which interventions help people adhere to compression treatments. This review is an update of a previous Cochrane review.

OBJECTIVES

To assess the benefits and harms of interventions designed to help people adhere to venous leg ulcer compression therapy, to improve healing and prevent recurrence after healing.

SEARCH METHODS

In June 2015, for this first update, we searched: The Cochrane Wounds Specialised Register; The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library); Ovid MEDLINE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations); Ovid EMBASE and EBSCO CINAHL. We also searched trial registries, and reference lists of relevant publications for published and ongoing trials. There were no language or publication date restrictions.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) of interventions that aim to help people with venous leg ulcers adhere to compression treatments compared with usual care, or no intervention, or another active intervention. Our main outcomes were ulcer healing, ulcer recurrence, quality of life, pain, adherence to compression therapy and number of people with adverse events.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected studies for inclusion, extracted data, assessed the risk of bias of each included trial, and assessed overall quality of evidence for the main outcomes in 'Summary of findings' tables.

MAIN RESULTS

One randomised controlled trial was added to this update making a total of three. One ongoing study was also identified.One trial (67 participants) compared a community-based Leg Club® that provided mechanisms for peer-support, assistance with goal setting and social interaction with home-based care. There was no clear difference in healing rates at three months (12/28 people healed in Leg Club group versus 7/28 in home-based care group; risk ratio (RR) 1.71, 95% confidence interval (CI) 0.79 to 3.71); or six months (15/33 healed in Leg Club group versus 10/34 in home-based care group; RR 1.55, 95% CI 0.81 to 2.93); or in quality of life outcomes at six months (MD 0.85 points, 95% CI -0.13 to 1.83; 0 to 10 point scale). The Leg Club may lead to a small reduction in pain at six months, that may not be clinically significant (MD -12.75 points, 95% CI -24.79, -0.71; 0 to 100 point scale, 15 point reduction is usually considered the minimal clinically important difference) (low quality evidence downgraded for risk of selection bias and imprecision).Another trial (184 participants) compared a community-based, nurse-led self-management programme of six months' duration promoting physical activity (walking and leg exercises) and adherence to compression therapy via counselling and behaviour modification (Lively Legs®) with usual care in a wound clinic. At 18 months follow-up, there were no clear differences in healing rates (51/92 healed in Lively Legs group versus 41/92 in usual care group; RR 1.24 (95% CI 0.93 to 1.67)); rates of recurrence of venous leg ulcers (32/69 with recurrence in Lively Legs group versus 38/67 in usual care group; RR 0.82 (95% CI 0.59 to 1.14)); or adherence to compression therapy (42/92 people fully adherent in Lively Legs group versus 41/92 in usual care group; RR 1.02 (95% CI 0.74 to 1.41)). The evidence from this trial was also downgraded to low quality due to risk of selection bias and imprecision.A single study compared patient education delivered via video with education delivered by text (pamphlet). However, no outcomes relevant to this review were reported.We found no studies that investigated other interventions to promote adherence to compression therapy.

AUTHORS' CONCLUSIONS

It is unclear whether interventions designed to help people adhere to compression therapy improve venous ulcer healing and reduce recurrence. There is a lack of trials of interventions that promote adherence to compression therapy for venous ulcers.

Contribution of the Leg Club model of care to the well-being of people living with chronic wounds

OBJECTIVE

Social support impacts well-being. Higher levels of social support encourage treatment adherence and aid healing in people living with chronic wounds. The Leg Club model of care harnesses social support mechanisms to improve patient outcomes. This study investigated whether social support mechanisms available through a Leg Club environment influenced well-being.

METHOD

Participants were community Leg Club members. Socio-demographic data was collected, and the Well-being in Wounds Inventory (WOWI) administered to assess 'wound worries,' 'personal resources,' and 'well-being'. Participants' perceived social situation, length of time attending a Leg Club, wound duration, and feelings about their physical appearance were also measured.

RESULTS

The subjects recruited (n=49) were aged between 50 and 94 years (mean=75.34, standard deviation=10.31). Membership of a Leg Club did impact well-being factors. Time spent at a Leg Club improved 'personal resources' over time. 'Perceived social situation' predicted key aspects of well-being, as did 'time spent attending a Leg Club' and 'feelings about physical appearance.' Social support and relief from social isolation were important aspects of Leg Club membership for participants.

CONCLUSION

Attending a Leg Club enhances well-being in people living with a chronic wound; social support has an important role to play in this relationship. Future research should consider the specific interplay of social support mechanisms of Leg Club, and other relevant wound-related variables to optimise patient well-being and treatment outcomes.

Stress-related changes to immune cells in the skin prior to wounding may impair subsequent healing

Higher psychological stress is associated with slower dermal wound healing, but the immunological mechanisms behind this effect are only partially understood. This paper aims to investigate whether immune cells present in the skin prior to wounding can affect subsequent healing in high-stress and low-stress participants. Two studies are presented in which skin biopsies were analysed using immunohistochemistry for numbers of macrophages and Langerhans cells, and immune cell activation (Study 2 only). Immune cells were related to perceived stress levels and subsequent healing. Study 1 included 19 healthy older adults and showed that higher stress was associated with significantly fewer macrophages in the skin. Study 2 included 22 younger adults and showed that higher stress was associated with significantly lower activation of immune cells in the skin. Furthermore, lower activation of immune cells (as measured by human leukocyte antigen (HLA expression)) and fewer Langerhans cells were associated with slower healing. Together these studies show the first preliminary evidence that the number and activation of immune cells in the skin prior to wounding are affected by stress and can impact healing. Larger studies are needed to confirm these effects.

Goal setting and lifestyle changes in a nurse-led counselling programme for leg ulcer patients: an explorative analysis of nursing records

AIMS AND OBJECTIVES

To describe goals set in individual nurse-led lifestyle counselling sessions in leg ulcer patients, and to explore patient and goal characteristics in relation to health behaviour change.

BACKGROUND

Goal setting is increasingly used in nurse-led counselling programmes, but the delivery is often unknown, especially in patient groups for which only recently programmes have been developed, such as patients with venous leg ulcers.

DESIGN

A secondary analysis of data collected in the intervention arm of a randomised clinical trial of counselling sessions in venous leg ulcer patients.

METHODS

Nursing records (n = 71) were explored for the number of goals set, topic, quality and course of goals during the trajectory. Furthermore, goals and patient characteristics were compared in relation to health behaviour change.

RESULTS

Forty-one patients (58%) succeeded in changing their behaviour after setting a goal. Setting goals for conducting leg exercises was chosen by most patients in this study, goals for adherence with compression therapy were chosen the least. Sixty-eight per cent of the goals met criteria for being Specific, Measurable and Time-bound. Patients who achieved behaviour change were significantly younger compared to the patients who did not. Except for age, there were no differences in characteristics between the group that did and did not achieve behaviour change.

CONCLUSIONS

Goal setting could be improved by setting goals more Specific, Measurable and Time-bound, and by setting goals on an essential topic for behaviour change. This explorative study did not show that goal characteristics, including the quality of goals, were related to patients' behaviour change.

RELEVANCE TO CLINICAL PRACTICE

The delivery of goal setting in this programme, and most likely in similar programmes, could be improved. Regular quality checks in daily goal setting practice should be considered. More research is needed into how to best provide health promotion to frail and elderly people.

A Multicenter Randomized Controlled Trial Comparing Treatment of Venous Leg Ulcers Using Mechanically Versus Electrically Powered Negative Pressure Wound Therapy

Objective: This study compares two different negative pressure wound therapy (NPWT) modalities in the treatment of venous leg ulcers (VLUs), the ultraportable mechanically powered (MP) Smart Negative Pressure (SNaP^®) Wound Care System to the electrically powered (EP) Vacuum-Assisted Closure (V.A.C.^®) System. Approach: Patients with VLUs from 13 centers participated in this prospective randomized controlled trial. Each subject was randomly assigned to treatment with either MP NPWT or EP NPWT and evaluated for 16 weeks or complete wound closure. Results: Forty patients (n=19 MP NPWT and n=21 EP NPWT) completed the study. Primary endpoint analysis of wound size reduction found wounds in the MP NPWT group had significantly greater wound size reduction than those in the EP NPWT group at 4, 8, 12, and 16 weeks (p-value=0.0039, 0.0086, 0.0002, and 0.0005, respectively). Kaplan-Meier analyses showed greater acceleration in complete wound closure in the MP NPWT group. At 30 days, 50% wound closure was achieved in 52.6% (10/19) of patients treated with MP NPWT and 23.8% (5/21) of patients treated with EP NPWT. At 90 days, complete wound closure was achieved in 57.9% (11/19) of patients treated with MP NPWT and 38.15% (8/21) of patients treated with EP NPWT. Innovation: These data support the use of MP-NPWT for the treatment of VLUs. Conclusions: In this group of venous ulcers, wounds treated with MP NPWT demonstrated greater improvement and a higher likelihood of complete wound closure than those treated with EP NPWT.

Scoping study into wound management nurse practitioner models of practice

OBJECTIVES

The primary objective of this research was to investigate wound management nurse practitioner (WMNP) models of service for the purposes of identifying parameters of practice and how patient outcomes are measured.

METHODS

A scoping study was conducted with all authorised WMNPs in Australia from October to December 2012 using survey methodology. A questionnaire was developed to obtain data on the role and practice parameters of authorised WMNPs in Australia. The tool comprised seven sections and included a total of 59 questions. The questionnaire was distributed to all members of the WMNP Online Peer Review Group, to which it was anticipated the majority of WMNPs belonged.

RESULTS

Twenty-one WMNPs responded (response rate 87%), with the results based on a subset of respondents who stated that, at the time of the questionnaire, they were employed as a WMNP, therefore yielding a response rate of 71% (n=15). Most respondents (93%; n=14) were employed in the public sector, with an average of 64 occasions of service per month. The typical length of a new case consultation was 60 min, with 32 min for follow ups. The most frequently performed activity was wound photography (83%; n=12), patient, family or carer education (75%; n=12), Doppler ankle-brachial pressure index assessment (58%; n=12), conservative sharp wound debridement (58%; n=12) and counselling (50%; n=12). The most routinely prescribed medications were local anaesthetics (25%; n=12) and oral antibiotics (25%; n=12). Data were routinely collected by 91% of respondents on service-related and wound-related parameters to monitor patient outcomes, to justify and improve health services provided.

CONCLUSION

This study yielded important baseline information on this professional group, including data on patient problems managed, the types of interventions implemented, the resources used to accomplish outcomes and how outcomes are measured.
