Effect of quality nursing intervention on wound healing in patients with burns: A meta-analysis.

This meta-analysis aimed to explore the effects of quality nursing intervention on wound healing in patients with burns. A computerised search was conducted for randomised controlled trials (RCTs) on the effect of quality nursing intervention on wound healing in patients with burns in the PubMed, Embase, Google Scholar, Cochrane Library, China National Knowledge Infrastructure and Wanfang databases from the date of database inception to November 2023. Two researchers independently screened the literature, extracted data and performed quality assessment based on the inclusion and exclusion criteria. Stata 17.0 software was used for the data analysis. Twenty-nine RCTs involving 2637 patients with burns were included. The meta-analysis revealed that compared with conventional nursing, the implementation of quality nursing intervention in patients with burns significantly shortened the wound healing time (standardised mean difference [SMD] = -2.93, 95% confidence interval [CI]: -3.44 to -2.42, p < 0.001). The incidence of wound infections (odds ratio [OR] = 0.14, 95% CI: 0.07-0.27, p < 0.001) and complications (OR = 0.16, 95% CI: 0.11-0.23, p < 0.001) was also reduced significantly. This meta-analysis shows that applying quality nursing interventions in patients with burns can significantly shorten the wound healing time and reduce the incidence of wound infection and complications, thus promoting early patient recovery.

Wound infections: an overview.

In the ever-changing world of wound care and nursing, it remains apparent that chronic wounds are a growing challenge. Evidence shows that age increases the likelihood of developing a chronic wound, which supports the notion that the burden of these wounds on the NHS is likely to further intensify with the ageing population. There are many reasons why a wound may fail to progress, including wound aetiology, comorbidities and environmental and socio-economic factors. One of the most significant reasons why wounds may fail to progress and become chronic is untreated wound infection. In order for clinicians to be able to treat and manage wound infections, it is vital that they understand how infection develops, the many ways in which infections may present themselves and how and when to initiate appropriate topical and systemic therapies to treat wound bed infections. The present article provides an overview of wound bed infections and their management.

Use of internally validated in vitro biofilm models to assess antibiofilm performance of silver-containing gelling fibre dressings.

OBJECTIVE: To assess the efficacy of five silver-containing gelling fibre wound dressings against single-species and multispecies biofilms using internally validated, UKAS-accredited in vitro test models. METHOD: Staphylococcus aureus, Pseudomonas aeruginosa and Candida albicans single- and multispecies biofilms were cultured using Centres for Disease Control (CDC) biofilm reactors and colony drip flow reactors (CDFR). Following a 72 hour incubation period, the substrates on which biofilms were grown were rinsed to remove planktonic microorganisms and then challenged with fully hydrated silver-containing gelling fibre wound dressings. Following dressing application for 24 or 72 hours, remaining viable organisms from the treated biofilms were quantified. RESULTS: In single-species in vitro models, all five antimicrobial dressings were effective in eradicating Staphylococcus aureus and Pseudomonas aeruginosa biofilm bacteria. However, only one of the five dressings (Hydrofiber technology with combination antibiofilm/antimicrobial technology) was able to eradicate the more tolerant single-species Candida albicans biofilm. In a more complex and stringent CDFR biofilm model, the hydrofiber dressing with combined antibiofilm/antimicrobial technology was the only dressing that was able to eradicate multispecies biofilms such that no viable organisms were recovered. CONCLUSION: Given the detrimental effects of biofilm on wound healing, stringent in vitro biofilm models are increasingly required to investigate the efficacy of antimicrobial dressings. Using accredited in vitro biofilm models of increasing complexity, differentiation in the performance of dressings with combined antibiofilm/antimicrobial technology against those with antimicrobial properties alone, was demonstrated.

Use of a TLC-Ag dressing on 2270 patients with wounds at risk or with signs of local infection: an observational study.

OBJECTIVE: A description of wounds treated with a poly-absorbent silver dressing (with technology lipido-colloid with silver ions, TLC-Ag), and evaluation of the short-term clinical impact of the dressing on the wound healing process, under real-life conditions. METHOD: A large, prospective, multicentre, observational study of patients in 81 centres in Germany, presenting with an exuding wound at risk or with clinical signs of local infection for whom the evaluated TLC-Ag dressing (UrgoClean Ag, Laboratoires Urgo, France) has been prescribed. Main outcomes included: reduction in number of wound infections diagnosed and clinical signs of local infection, wound healing rate, clinical assessment of wound healing progression, relative wound area reduction (RWAR), local tolerability, handling and acceptance of the dressing. RESULTS: A total of 2270 patients with acute and chronic wounds of various aetiologies were treated with the evaluated dressing for a mean duration of 22±13 days. All clinical signs of local infection and the diagnosed wound infections were substantially reduced at two weeks after the treatment initiation. All wound infection parameters continued to reduce until the last visit. In the meantime, clinical improvement in wound healing was reported in 98.9% of acute wounds, with a wound closure rate of 68.5%. In chronic wounds, a median RWAR of 57.4% was achieved, with an improvement in healing process documented by clinicians in 90.6% of cases, stabilisation in 6.1% and worsening in 3.2%. Similar results were reported, regardless of exudate level and proportion of sloughy and granulation tissues in the wound bed at baseline. The dressing was well tolerated and well accepted by both patients and health professionals. CONCLUSION: These results, documented in a large cohort of patients treated in current practice, support and complete the clinical evidence on the healing properties and safety profile of the TLC-Ag dressing in the management of wounds at risk or with clinical signs of local infection, regardless of wound and patient characteristics.

Evaluar competencia clínica del profesional de enfermería, para identificación de infección en la herida de un paciente / Evaluate clinical competence of the nursing professional to identify infection to a patient's wound Abstract

Objetivo: determinar el nivel de competencia del profesional de enfermería para identificar infección en la herida de un paciente, en dos instituciones de la ciudad de Medellín. Método: es un abordaje cuantitativo, descriptivo de corte transversal. Muestra: 116 profesionales de enfermería que se desempeñan en áreas asistenciales. Instrumento: cuestionario ad hoc, que evalúa las competencias clínicas del profesional de enfermería para reconocer infección en la herida del paciente. El análisis de los datos se realizó mediante estadística descriptiva y los datos fueron procesados en Excel 2016, y SPSS Versión 25. Resultados: el nivel de competencia clínica del profesional de enfermería puntuó en nivel medio, para las categorías de actitud, habilidad y conocimiento no hubo mayores diferencias, aunque en actitud los profesionales alcanzaron nivel bueno, ninguno llegó a nivel alto. Se evidenció que un 92,2% guían su diagnóstico de infección de la herida a través de signos clásicos de infección aguda (rubor, calor, edema, empastamiento y dolor), y que un 50% de los participantes identificaban tecnologías en apósitos para el tratamiento local de la infección de la herida. No se encontró relación entre nivel de competencia clínica y experiencia asistencial, quienes realizaron diplomado en cuidado de heridas, mostraron mejor actitud en el cuidado de heridas, se hallaron diferencias significativas entre el nivel de competencia clínica y el número de pacientes que atendían los profesionales, alcanzando nivel bueno quienes atendían 20 pacientes o más. Conclusión: el nivel de competencia clínica de los profesionales de enfermería para identificar infección en la herida de un paciente es medio, lo que infiere la necesidad de fortalecer estas competencias en el pregrado, motivar participación en diplomados y certificaciones en el tema e instar a las instituciones para favorecer habilidades, conocimiento y actitud en el cuidado de pacientes que tienen heridas en riesgo de infección o infectadas.

Objective: to determine the level of competence of the nursing professional to identify infection in a patient's wound, in two institutions in the city of Medellín. Method: it is a quantitative, descriptive, cross-sectional. Sample: 116 nursing professionals, involved in healthcare areas. Resource used: ad hoc questionnaire, which assesses the clinical skills of the nursing professional to identify infection in the patient's wound. Data analysis was performed using descriptive statistics and the data were processed in Excel (2016), and SPSS Version 25. Results: the level of clinical competence of the nursing professional scored at a medium level, for the categories of attitude, ability and knowledge there were no major differences, although in attitude the professionals reached a good level, none reached a high level. It is evidenced that 92.2% guide their diagnosis of wound infection through classic signs of acute infection (redness, heat, edema, filling and pain), and that 50% of the participants identified technologies in dressings for treatment local wound infection. No relationship was found between level of clinical competence and care experience, those who completed a diploma in wound care, improved attitude in wound care, significant differences were found between the level of clinical competence and the number of patients attended by professionals, reaching good level who attended 20 patients or more. Conclusion: the level of clinical competence of nursing professionals to identify infection in the wound of a patient is medium, which implies the need to strengthen, undergraduate, motivate participation in diplomas and certifications on the subject and urge institutions to favor skills, knowledge and attitude in the care of patients who have wounds at risk of infection or infected.

Defying hard-to-heal wounds with an early antibiofilm intervention strategy: 'wound hygiene'.

Biofilm has been implicated as a barrier to wound healing and it is widely accepted that the majority of wounds not following a normal healing trajectory contain biofilm. Therefore, strategies that inform and engage clinicians to reduce biofilm and optimise the wound tissue environment to enable wound progression are of interest to wound care providers. In March 2019, an advisory board was convened where experts considered the barriers and opportunities to drive a broader adoption of a biofilm-based approach to wound care. Poor clarity and articulation of wound terminology were identified as likely barriers to clinical adoption of rigorous and proactive microbial decontamination that is supportive of wound healing advancement. A transition to an intuitive term such as 'wound hygiene' was proposed to communicate a comprehensive wound decontamination plan with an associated message of expected habitual routine. 'Wound hygiene', is a relatable concept that supports meticulous wound practice that addresses barriers to wound healing, such as biofilm, while aligning with antimicrobial stewardship programmes.

Cost-effectiveness of adjunct haemoglobin spray in the treatment of hard-to-heal wounds in a UK NHS primary care setting.

OBJECTIVE: To evaluate the cost-effectiveness of topical haemoglobin spray as adjunct therapy in the treatment of hard-to-heal wounds within a UK National Health Service (NHS) community setting. METHOD: In a previously published comparative clinical evaluation, 50 consecutive patients treated with topical haemoglobin spray, as adjunct to standard care and followed up over 26 weeks, were compared with 50 consecutive retrospective controls from the same clinic treated with the same standard care protocol in the year prior to the introduction of adjunct topical haemoglobin spray. A de novo cost-effectiveness and break-even analysis were performed, using data from the previously published clinical evaluation, for all patients (intent-to-treat) and for patients with complete follow-up using a micro-costing approach and considering only wound care dressing costs. RESULTS: At 26 weeks, the total cost of dressings for all patients in the intervention group was £6953 with 874 cumulative weeks healed, compared with £9547 with 278 cumulative weeks healed for all patients in the control group. The incremental cost-effectiveness ratio (ICER), the incremental cost per additional week healed with adjunct topical haemoglobin spray, is therefore negative (dominant). Total treatment costs per week were lower from week six onwards, with break-even estimated to be at week 10.2. When considering only patients with complete follow-up, the results were similarly dominant, with a mean 10.9 more weeks healed, a mean dressing cost saving per patient of £81.83 by week 26 (-37%). Cost savings were realised from week five, and a break-even was estimated to occur at week 8.0. CONCLUSION: Topical haemoglobin spray has the potential to restore the healing process, reduce healing times and reduce dressing costs in a NHS community setting, within a few weeks of adoption.

Chronic wounds: the challenges of appropriate management.

The immense burden imposed by chronic wounds-those persisting over 6 weeks despite active intervention-on patients and health services is well recognised. There are various reasons for why a wound fails to progress towards closure, and clinicians must investigate the underlying cause of wound chronicity, as this information guides the management of such wounds. The TIME framework (T=tissue; I=infection/inflammation; M=moisture balance; E=wound edges) is a useful tool for practitioners to systematically undertake wound assessment and product selection. This article discusses chronic wound management based on the TIME framework, examining the aspects to be considered when managing chronic wounds. It also describes the process of dressing selection for overcoming the various barriers to wound healing, specifically discussing the AQUACEL family of dressings.

Identifying and managing wound infection in the community.

A large proportion of community wound care consists of managing chronic wounds. Given the increasingly complex patient comorbidities, early identification and treatment of wound infection can impact greatly not only on wound healing but also on the patient physically, psychologically and socially. Identifying wound infection can be challenging for clinicians, particularly in the chronic wound where infection may not always present itself as it does in acute wounds. The management of infected wounds can be complicated. Managing multiple symptoms and recognising these as being due to infection is not always straightforward and relies on the practitioner's knowledge and skills. An understanding of more commonly used antimicrobial treatments and when to employ these is paramount in enabling the practitioner to provide care that is effective, evidence based and cost efficient.

When and How to Perform Cultures on Chronic Wounds?

PURPOSE: The purpose of this Evidence-Based Report Card was to examine current best evidence related to when and how to perform cultures on chronic wounds to guide clinicians in determining the appropriate treatment. QUESTION: (1) When should cultures be performed on chronic wounds? and (2) What is the best method or technique to perform a culture on a chronic wound? SEARCH STRATEGY: A search of the literature was performed, resulting in 45 publications relevant to the topic. Following a review of titles and abstracts, 7 studies were identified that met inclusion criteria. Key search terms used were "chronic wound," "chronic infected wound," "wound culture," "specimen collection," and "wound swab." Strength of the evidence was rated based on the methodology from Essential Evidence Plus: Levels of Evidence and Oxford Center for Evidence-Based Medicine, adapted by Gray and colleagues. FINDINGS: Seven studies were identified as pertinent to the topic on wound culture and meeting inclusion criteria. The study designs included 1 randomized controlled trial, 1 quasi-experimental comparative study, 1 systematic review, 1 scoping literature review, 1 integrative literature review, and 2 professional organization expert panel reviews (consensus statement and position statement). Of the 7 studies, 3 studies suggest that classic signs of infection may not always be present but culturing may be indicated when additional signs such as pain, necrotic tissue, prolonged or delayed healing, and wound bed deterioration occur. Four studies report that a quantitative culture of wound tissue is the gold standard to obtain a wound culture, but the swab method is an acceptable alternative option. Two articles demonstrate the Levine technique is more reliable than the Z-technique to determine microbial load in the wound bed. The strength of the evidence was identified as 2 level A studies, 1 level B study, and 4 level C studies. Using Johns Hopkins methodology, the quality of the studies was deemed either high quality or good quality. CONCLUSION/RECOMMENDATION: Evidence indicates that identification of potential chronic wound infection should be considered early using clinical signs such as pain, necrotic tissue, delayed healing, and wound deterioration (in addition to classic signs of infection) to determine the need for collecting a culture (Strength of Recommendation Taxonomy [SORT] level 2); and when a culture is deemed necessary, swab culture using the Levine method is a clinically practical alternative if performed correctly (SORT level 1).

Teaching Wound Care to Family Caregivers.

: This article is part of a series, Supporting Family Caregivers: No Longer Home Alone, published in collaboration with the AARP Public Policy Institute. Results of focus groups, conducted as part of the AARP Public Policy Institute's No Longer Home Alone video project, supported evidence that family caregivers aren't given the information they need to manage the complex care regimens of family members. This series of articles and accompanying videos aims to help nurses provide caregivers with the tools they need to manage their family member's health care at home.The articles in this new installment of the series provide simple and useful instructions that nurses should reinforce with family caregivers who perform wound care tasks. Each article also includes an informational tear sheet-Information for Family Caregivers-that contains links to instructional videos. To use this series, nurses should read the article first, so they understand how best to help family caregivers, and then encourage caregivers to watch the videos and ask questions. For additional information, see Resources for Nurses.

Early wound infection identification using the WIRE tool in community health care settings: An audit report.

Wound infection is proving to be a challenge for health care professionals. The associated complications and cost of wound infection is immense and can lead to death in extreme cases. Current management of wound infection is largely subjective and relies on the knowledge of the health care professional to identify and initiate treatment. In response, we have developed an infection prediction and assessment tool. The Wound Infection Risk-Assessment and Evaluation tool (WIRE) and its management strategy is a tool with the aim to bring objectivity to infection prediction, assessment and management. A local audit carried out indicated a high infection prediction rate. More work is being done to improve its effectiveness.

[A new cleansing technique for complex wounds]. / Une nouvelle technique de détersion pour les plaies complexes.

Fast, effective and pain-free cleansing is essential in the management of wounds, in order to favour the formation of the granulation tissue and the filling of the cavity. Faced with a chronic wound which was not progressing from the inflammatory phase, caregivers put in place a technique combining negative pressure therapy and instillations of sodium bicarbonate and oxygenated water. The initial results are promising, with the patient benefiting from effective and pain-free cleansing.

Wound Infections in Critical Care.

Patients admitted to critical care units are at high risk for increased morbidity and mortality from skin and deep wound infections. Despite considerable progress, wound healing remains a challenge to many clinicians. Nurses working in critical care environments need to understand the anatomic and physiologic basis for wound healing, distinguish wound inflammation from wound infection, recognize the presence of biofilms, and implement evidence-based wound care in order to promote successful outcomes in this patient population.

Topical Corticosteroid for the Treatment of Hypergranulation Tissue at the Gastrostomy Tube Insertion Site: A Case Study.

Hypergranulation tissue formation around a gastrostomy tube insertion site is a common feeding tube-related complication that affects patients who receive long-term enteral nutrition. Some clinicians recommend use of a topical corticosteroid in patients with gastrostomy tube insertion site hypergranulation. However, documentation is scant regarding appropriate treatment for this condition. This case report describes a 67-year-old bedridden man with spinocerebellar degeneration who presented with hypergranulation at the site of the gastrostomy tube, inserted 1 week earlier. The tissue was raw and inflamed, with bleeding and exudation. The gastrostomy site was gently cleansed with gauze dampened with tap water, and topical 0.05% clobetasol propionate ointment was applied directly to the hypergranulation tissue twice daily. After 4 days of treatment, the hypergranulation tissue almost completely disappeared, redness markedly decreased, and bleeding and exudation ceased, with no recurrence observed during the 6 months of follow-up. This case study supports other reports that short-term corticosteroid treatment may be a safe, quick, noninvasive, and effective treatment for hypergranulation at the gastrostomy tube insertion site. Further studies are needed to evaluate the safety, effectiveness, appropriate dosage, and duration of topical corticosteroid for the treatment of hypergranulation tissue.

Management of diabetic foot ulcers: evaluation of case studies.

This article explores local barriers to diabetic foot ulcer healing, and describes the use of a dressing designed to manage exudate, infection and biofilm (AQUACEL® Ag+ dressing (AQAg+)) on recalcitrant diabetic foot ulcers. The authors consider four case studies that demonstrate how managing local barriers to wound healing with antimicrobial and anti-biofilm dressings in protocols of care can improve outcomes for patients.
