Evidence generation for wound care dressing selection: reviewing the issues

Silver nanoparticle dressing: The knowledge of advantages and limits improves the indications in clinical practice

Silver nanoparticle dressings have gained popularity recently as a way to treat challenging wounds. Notwithstanding the properties of Ag-NPS (silver nanoparticles) described by several articles, there is a lack of clinical studies that guide healthcare professionals to specific and conscious use. In this case series, Ag-NPS dressing was tested on a randomized group of 10 patients with complex wounds requiring conservative treatment. Each case was analysed, recording the patient's history, the peculiar characteristics and the progressive changes in the wound. The wound bed and the quality of the peri-wound skin improved and a decrease in signs of infection was observed. The application of the dressing was simple and comfortable for the patient and it was appreciated for its sealing ability. A few capacity restrictions showed up: those should be read as elements to improve the indications for this peculiar dressing. The thin tissue matrix of the Ag-NPS dressing does not allow for massive absorption and also performs poorly in reducing little exudate. The reduction in wound width is also limited: reconstructive surgery was required in half of the enrolled patients to achieve wound healing.

Applications of MXene and its modified materials in skin wound repair

The rapid healing and repair of skin wounds has been receiving much clinical attention. Covering the wound with wound dressing to promote wound healing is currently the main treatment for skin wound repair. However, the performance of wound dressing prepared by a single material is limited and cannot meet the requirements of complex conditions for wound healing. MXene is a new two-dimensional material with electrical conductivity, antibacterial and photothermal properties and other physical and biological properties, which has a wide range of applications in the field of biomedicine. Based on the pathophysiological process of wound healing and the properties of ideal wound dressing, this review will introduce the preparation and modification methods of MXene, systematically summarize and review the application status and mechanism of MXene in skin wound healing, and provide guidance for subsequent researchers to further apply MXene in the design of skin wound dressing.

Diabetic foot ulcers: A devastating complication of diabetes mellitus continues non-stop in spite of new medical treatment modalities

Diabetic foot ulcer is a devastating complication of diabetes mellitus and significant cause of mortality and morbidity all over the world and can be complex and costly. The development of foot ulcer in a diabetic patient has been estimated to be 19%-34% through their lifetime. The pathophysiology of diabetic foot ulcer consist of neuropathy, trauma and, in many patients, additional peripheral arterial disease. In particular, diabetic neuropathy leads to foot deformity, callus formation, and insensitivity to trauma or pressure. The standard algorithms in diabetic foot ulcer management include assessing the ulcer grade classification, surgical debridement, dressing to facilitate wound healing, off-loading, vascular assessment (status and presence of a chance for interventional vascular correction), and infection and glycemic control. Although especially surgical procedures are sometimes inevitable, they are poor predictive factors for the prognosis of diabetic foot ulcer. Different novel treatment modalities such as nonsurgical debridement agents, oxygen therapies, and negative pressure wound therapy, topical drugs, cellular bioproducts, human growth factors, energy-based therapies, and systematic therapies have been available for patients with diabetic foot ulcer. However, it is uncertain whether they are effective in terms of promoting wound healing related with a limited number of randomized controlled trials. This review aims at evaluating diabetic foot ulcer with regard to all aspects. We will also focus on conventional and novel adjunctive therapy in diabetic foot management.

Essentials of wound care: assessing and managing impaired skin integrity

The assessment and management of impaired skin integrity as part of wound care is a common nursing task. Specific wound assessment tools may assist nurses to structure an assessment, but wider holistic factors also need to be considered. The TIMERS (tissue, inflammation and infection, moisture balance, edge, repair and regeneration, and social factors) tool offers a flexible approach to assessing wounds holistically and can be applied in all wound aetiologies. This article provides nurses with an overview of the assessment and management of impaired skin integrity using the TIMERS tool. It also discusses the importance of shared decision-making between nurses and patients when formulating a wound care regimen.

The use and meaning of the parachute metaphor in biomedicine: a citation analysis of a systematic review and a randomized trial of the parachute for freefall

Background: Numerous authors have used the 'parachute' analogy to comment on the importance of and need for randomized, controlled trials (RCTs) in the hierarchy of medical evidence. Methods: The authors completed a retrospective literature analysis examining publications citing the 2003 parachute paper by Smith and Pell and a 2018 RCT of a parachute by Yeh et al. For all of the articles that directly analogized a medical intervention to a parachute, the authors identified the desired outcome of the practice and searched PubMed for relevant RCTs. Results: Authors citing the parachute analogy are often critical of RCTs and often draw comparisons to interventions that are not parachutes.

Le transfert des connaissances en soins de plaies chez les infirmières : une revue intégrative des écrits

Introduction : Wound care represents a public health issue and is an important concern for nursing care.Context : Despite the availability of best practice recommendations and clinical practice guidelines, there is a lack of use of this evidence in clinical practice.Objectives : The aim of this integrative review is to identify the barriers to nurses’ optimal knowledge transfer in wound care.Method : An integrative literature review based on Whittemore and Knalf’s (2005) methodology was conducted ; six databases were searched.Results : Of the 82 articles that were retrieved, 13 were retained for analysis. They were all published in English. The literature highlights a theory–practice gap in wound care. Barriers related to knowledge, attitudes, and environmental factors contribute to this gap.Discussion : Nursing could benefit from interventions to improve its role in wound care. The perspectives of new graduate nurses as well as nurses working in rural healthcare settings were limited.Conclusion : A strategic plan, adapted to the situation of each healthcare facility, could improve the quality of wound care practice.

Routine Fluorescence Imaging to Detect Wound Bacteria Reduces Antibiotic Use and Antimicrobial Dressing Expenditure While Improving Healing Rates: Retrospective Analysis of 229 Foot Ulcers

Foot ulcers and their bacterial burden produce a significant strain on the National Healthcare System (NHS). Subjectivity of wound infection assessment makes appropriate dressing selection challenging. To aid point-of-care detection of bacterial burden, a fluorescence imaging device (MolecuLight i:X) was introduced to the Whipps Cross Hospital Podiatry clinic. This retrospective pre/post-analysis evaluated how implementation of fluorescence imaging impacted (1) antimicrobial dressings and antibiotics use and (2) wound healing rates. Over a 2-year period 229 lower extremity wounds were treated. Wound-related outcomes and antimicrobial dressing costs were quantified over 1-year before (2018/2019) and after (2019/2020) incorporating fluorescence imaging into routine practice. The period of fluorescence imaging saw a 27% increase in the number of wounds seen, yet annual antimicrobial dressing expenditure decreased by 33%. Implementation of fluorescence imaging was also associated with a 49% decrease in prescription of antimicrobial dressings, a 33% decrease in antibiotic prescriptions, and a 23% increase in wound healing rates within 12-weeks (48% vs. 39%), likely due to earlier bacterial detection and improved wound hygiene. This increased healing rate is projected to decrease annual wound costs by 10% (£762 per patient). Routine bacterial imaging appears to diminish clinical and economic burden to patients and the NHS.

First-Line Interactive Wound Dressing Update: A Comprehensive Review of the Evidence

Wound management is a significant and growing issue worldwide. Knowledge of dressing products and clinical expertise in dressing selection are two major components in holistic wound management to ensure evidence-based wound care. With expanding global market of dressing products, there is need to update clinician knowledge of dressing properties in wound care. Optimal wound management depends on accurate patient assessment, wound diagnosis, clinicians’ knowledge of the wound healing process and properties of wound dressings. We conducted a comprehensive review of the physical properties of wound dressing products, including the advantages and disadvantages, indications and contraindications and effectiveness of first-line interactive/bioactive dressing groups commonly used in clinical practice. These include semipermeable films, foams, hydroactives, alginates, hydrofibers, hydrocolloids, and hydrogels. In making decisions regarding dressing product selection, clinicians need to ensure a holistic assessment of patient and wound etiology, and understand dressing properties when making clinical decisions using wound management guidelines to ensure optimal patient outcomes. This review has highlighted there is lack of high quality evidence and the need for future well designed trials.

Embedding National Institute for Health and Care Excellence guidance into a leg ulcer pathway

Research has shown that leg ulcers represent the largest category of wound type treated within the UK. Venous leg ulcers are often classified as chronic wounds with increased protease levels causing the wound to become suspended in the inflammatory stage, which leads to delayed healing. If treatment choices are not evidence-based and appropriate regimens are not instigated early on in the wound care journey, the cost to both the patient and the healthcare service is substantial. Recent guidance from the National Institute of Health and Care Excellence (NICE) recommends UrgoStart (Urgo Medical) for treating venous leg ulcers as an adjunct therapy to the gold standard of compression therapy. Correct treatment choices must be made by clinicians using up-to-date relevant wound care knowledge. Evidence-based treatment algorithms and pathways can assist with correct product and therapy placement, assisting decision-making to improve patient outcomes. The present article describes a patient-centred leg ulcer pathway that embeds NICE guidance.

Wound care in older adults

Wound care in older adults is complex. A logical, structured approach should be taken, using a nursing process such as assessing, planning, implementing and evaluating. This clinical focus paper outlines the nursing process to support wound care in this patient group. It recommends considering dressing selection as a cost-effective, prescribing decision because of the risks and comorbidities associated with these patients.

Viewing dressing evaluation through a pragmatic lens: The application of Dewey's experimentalism in the development of evidence for dressing selection

RATIONALE, AIMS, AND OBJECTIVES

The aim of this paper is to (1) summarize the challenges with developing evidence for dressing selection in wound care, (2) discuss the limiting influence that the Evidence-Based Practice movement has had in this field, and (3) discuss the opportunities offered by Dewey's theory of experimentalism as a pragmatic solution to develop a structured body of evidence.

FINDINGS

Whilst the number of dressings available on the market continue to proliferate, limited progress has taken place to develop a methodology for dressing evaluation that is relevant to clinical practice. It is proposed that experimentalism can be operationalized with a mixed-methods approach that may include the following: (1) medical histories and patient's stories; (2) participant observation and informal interviews; (3) a comparative study between a new dressing and standard care; (4) a patient's satisfaction survey; (5) a staff survey; (6) a cost examination; (7) an evaluation of the packaging and procurement route; and finally (8) a clinical meeting to triangulate the data and reach a consensus.

CONCLUSION

Experimentalism offers a framework for the construction of evidence used for dressing selection. Central to this concept is the integration of experience to the data collected. The context of the evaluation has equal weight to the data thus collected.
