RESUMEN
It is common for community-based healthcare providers (CHPs)-many of whom have not received specialised training in wound care-to deliver initial and ongoing management for various wound types and diverse populations. Wounds in any setting can rapidly transition to a stalled, hard-to-heal wound (HTHW) that is not following a normal healing trajectory. Failure to recognise or address issues that cause delayed healing can lead to increased costs, healthcare utilisation and suffering. To encourage early intervention by CHPs, a panel of wound care experts developed actionable evidence-based recommendations for CHPs delineating characteristics and appropriate care in identifying and treating HTHWs. A HTHW is a wound that fails to progress towards healing with standard therapy in an orderly and timely manner and should be referred to a qualified wound care provider (QWCP) for advanced assessment and diagnosis if not healed or reduced in size by 40%-50% within 4 weeks. HTHWs occur in patients with multiple comorbidities, and display increases in exudate, infection, devitalised tissue, maceration or pain, or no change in wound size. CHPs can play an important initial role by seeing the individual's HTHW risk, addressing local infection and providing an optimal wound environment. An easy-to-follow one-page table was developed for the CHP to systematically identify, evaluate and treat HTHWs, incorporating a basic toolkit with items easily obtainable in common office/clinic practice settings. A flow chart using visual HTHW clinical cues is also presented to address CHPs with different learning styles. These tools encourage delivery of appropriate early interventions that can improve overall healthcare efficiency and cost.

The Wound Healing Foundation (WHF) recognised a need for an unbiased consensus on the best treatment of chronic wounds. A panel of 13 experts were invited to a virtual meeting which took place on 27 March 2021. The proceedings were organised in the sub-sections diagnosis, debridement, infection control, dressings, grafting, pain management, oxygen treatment, outcomes and future needs. Eighty percent or better concurrence among the panellists was considered a consensus. A large number of critical questions were discussed and agreed upon. Important takeaways included that wound care needs to be simplified to a point that it can be delivered by the patient or the patient's family. Another one was that telemonitoring, which has proved very useful during the COVID-19 pandemic, can help reduce the frequency of interventions by a visiting nurse or a wound care center. Defining patient expectations is critical to designing a successful treatment. Patient outcomes might include wound specific outcomes such as time to heal, wound size reduction, as well as improvement in quality of life. For those patients with expectations of healing, an aggressive approach to achieve that goal is recommended. When healing is not an expectation, such as in patients receiving palliative wound care, outcomes might include pain reduction, exudate management, odour management and/or other quality of life benefits to wound care.

ABSTRACT: Wound infection is a major challenge for clinicians globally, with accurate and timely identification of wound infection being critical to achieving clinical and cost-effective management, and promotion of healing. This paper presents an overview of the development of the International Wound Infection Institute (IWII)'s 2022 Wound Infection in Clinical Practice consensus document. The updated document summarises current evidence and provides multidisciplinary healthcare providers with effective guidance and support on terminology, paradigms related to biofilm, identification of wound infection, wound cleansing, debridement and antimicrobial stewardship. Integral to the update is revision of wound infection management strategies which are incorporated within the IWII's Wound Infection Continuum (IWII-WIC) and management plan. The aim of the 2022 IWII consensus document update was to provide an accessible and useful clinical resource in at least six languages, incorporating the latest evidence and current best practice for wound infection and prevention. Dissemination techniques for the consensus are discussed and highlighted.

FOREWORD. WOUND HYGIENE: THE NEXT STAGE: Since a panel published the first consensus document on Wound Hygiene in March 2020, there has been a flurry of activity in support of this newly established concept in proactive wound healing.1 The document concluded that all wounds, particularly hard-to-heal ones, will benefit from Wound Hygiene, which should be initiated at the first referral, following a full holistic assessment to identify the wound aetiology and comorbidities, and then implemented at every dressing change until full healing occurs.1 The consensus has since been bolstered by educational webinars; competency-based skills training and support; development of international Wound Hygiene ambassadors; a survey of 1478 respondents, published in July 2021;2 and a case study supplement, published in January 2022, featuring a range of wound types, anatomies and underlying conditions on the improvements in wound-healing progress that can be achieved.3 Wound Hygiene has gained its own identity and is now a term in and of itself, that encompasses a 4-step protocol of care. It is an antibiofilm approach that is increasingly being used across wound care. The results of the survey2 were particularly encouraging for seeing how far Wound Hygiene has come, and how quickly: More than half (57.4%) had heard of the concept of Wound Hygiene Of those, 75.3% have implemented Wound Hygiene Overall, following implementation of Wound Hygiene, 80.3% of respondents reported improved healing rates.2 However, the top three barriers identified by the survey-lack of confidence, competence and research data-show that there is more to be done to support Wound Hygiene in practice.2 As a result, a consensus panel of international key opinion leaders convened virtually in the summer of 2021 to discuss what has been done so far, the outputs of the survey, and ideas for addressing the unmet needs identified by the results. The result is this publication, which represents an addendum to the initial consensus document, broadening support for implementation of Wound Hygiene. This document will reflect on the reasons Wound Hygiene has been successful in its first two years of implementation, reiterating its DNA: Do not wait to treat hard-to-heal wounds Use a simple 4-step approach Enable all healthcare professionals to implement and use Wound Hygiene. The document will also discuss the evolution of the Wound Hygiene concept, focusing on how and when to implement Wound Hygiene on all tissue types of hard-to-heal wounds, and proposing what these are. The panel has expanded the framework in which Wound Hygiene is used, with the ultimate objective of introducing the concept of 'embedding Wound Hygiene intro a proactive wound healing strategy.' Key inefficiencies are often observed along the journeys of people living with hard-to-heal wounds. The limited number of specialised healthcare professionals and the resulting delays in reaching them may increase the likelihood of a hard-to-heal wound developing. In a world where so much is happening so quickly that we may, at times, feel powerless to drive change, the panel wants to provide further guidance to propel the use of Wound Hygiene. The concept of Wound Hygiene is resonating, and the panel wants you to know that in whatever region you work, in whatever area of clinical practice, you are enabled to make this change. Wielding the 4-step Wound Hygiene protocol consistently is a key action every healthcare professional in every care setting can take to tackle the global wound care crisis. Wound Hygiene has taken off-now, where do we want to land? In a place where Wound Hygiene is practised on all wounds, at every stage, until healing. The panel once again recognises that the community of global healthcare providers should consider their local standards and guidelines when applying the recommendations of this document. To this end, the panel has created a flexible 3-phase framework that situates Wound Hygiene as integral to proactive wound healing. The panel hopes you will continue to implement Wound Hygiene and see the benefits it can bring to people living with wounds, as well as those who care for them.

Chronic, nonhealing wounds consume a great deal of healthcare resources and are a major public health problem, associated with high morbidity and significant economic costs. Skin grafts are commonly used to facilitate wound closure. The grafts can come from the patient's own skin (autograft), a human donor (allograft), or from a different species (xenograft). A fish skin xenograft from cold-water fish (Atlantic cod, Gadus morhua) is a relatively recent option that shows promising preclinical and clinical results in wound healing. Chronic wounds vary greatly in etiology and nature, requiring large cohorts for effective comparison between therapeutic alternatives. In this study, we attempted to imitate the status of a freshly debrided chronic wound by creating acute full-thickness wounds, 4 mm in diameter, on healthy volunteers to compare two materials frequently used to treat chronic wounds: fish skin and dHACM. The purpose is to give an indication of the efficacy of the two therapeutic alternatives in the treatment of chronic wounds in a simple, standardized, randomized, controlled, double-blind study. All volunteers were given two identical punch biopsy wounds, one of which was treated with a fish skin graft and the other with dehydrated human amnion/chorion membrane allograft (dHACM). In the study, 170 wounds were treated (85 wounds per group). The primary endpoint was defined as time to heal (full epithelialization) by blinded assessment at days 14, 18, 21, 25, and 28. The superiority hypothesis was that the fish skin grafts would heal the wounds faster than the dHACM. To evaluate the superiority hypothesis, a mixed Cox proportional hazard model was used. Wounds treated with fish skin healed significantly faster (hazard ratio 2.37; 95% confidence interval: (1.75-3.22; p = 0.0014) compared with wounds treated with dHACM. The results show that acute biopsy wounds treated with fish skin grafts heal faster than wounds treated with dHACM.

Biofilms play a central role in the chronicity of non-healing lesions such as venous leg ulcers and diabetic foot ulcers. Therefore, biofilm management and treatment is now considered an essential part of wound care. Many antimicrobial treatments, whether topical or systemic, have been shown to have limited efficacy in the treatment of biofilm phenotypes. The antimicrobial properties of iodine compounds rely on multiple and diverse interactions to exert their effects on microorganisms. An expert panel, held in Las Vegas during the autumn Symposium on Advanced Wound Care meeting in 2018, discussed these properties, with the focus on iodine and iodophors and their effects on biofilm prevention and treatment.

Products that provide a protective skin barrier play a vital role in defending the skin against the corrosive effect of bodily fluids, including wound exudate, urine, liquid faeces, stoma output and sweat. There are many products to choose from, which can be broadly categorised by ingredients. This article describes the differences in mechanisms of action between barrier products comprising petrolatum and/or zinc oxide, silicone film-forming polymers and cyanoacrylates, and compares the evidence on them. The literature indicates that all types of barrier product are clinically effective, with little comparative evidence indicating that any one ingredient is more efficacious than another, although film-forming polymers and cyanoacrylates have been found to be easier to apply and more cost-effective. However, laboratory evidence, albeit limited, indicates that a concentrated cyanoacrylate produced a more substantial and adherent layer on a porcine explant when compared with a diluted cyanoacrylate and was more effective at protecting skin from abrasion and repeated exposure to moisture than a film-forming polymer. Finally, a silicone-based cream containing micronutrients was found to significantly reduce the incidence of pressure ulceration when used as part of a comprehensive prevention strategy.

Despite the understanding that wounds are a common problem affecting the individual, the health service and society as a whole, there continues to be a lack of a systematic, structured, evidence-based approach to wound management. The TIME principle was first published in 2003, 1 and has since been integrated by many into clinical practice and research. However, this tool has been criticised for its tendency to focus mainly on the wound rather than on the wider issues that the patient is presenting with. At an expert meeting held in London in 2018, this conundrum was addressed and the TIME clinical decision support tool (CDST) was elaborated upon. This article introduces the TIME CDST, explains why it is required and describes how its use is likely to benefit patients, clinicians and health-service organisations. It also explores the framework in detail, and shows why this simple and accessible framework is robust enough to facilitate consistency in the delivery of wound care and better patient outcomes. Finally, it outlines the next steps for the rollout, use and evaluation of the impact of the TIME CDST.

Appropriate and effective wound cleaning represents an important process that is necessary for preparing the wound for improved wound healing and for helping to dislodge biofilms. Wound cleaning is of paramount importance to wound bed preparation for helping to enhance wound healing. Surfactant applications in wound care may represent an important area in the cleaning continuum. However, understanding of the role and significance of surfactants in wound cleansing, biofilm prevention and control, and enhancing cellular viability and proliferation is currently lacking. Despite this, some recent evidence on poloxamer-based surfactants where the surfactants are present in high concentration have been shown to have an important role to play in biofilm management; matrix metalloproteinase modulation; reducing inflammation; and enhancing cellular proliferation, behaviour, and viability. Consequently, this review aims to discuss the role, mode of action, and clinical significance of the use of medically accepted surfactants, with a focus on concentrated poloxamer-based surfactants, to wound healing but, more specifically, the role they may play in biofilm management and effects on cellular repair.

OBJECTIVE: Removal of slough and other devitalised tissue is an important step in biofilm-based wound care (BBWC) and wound bed preparation. Debridement is key to management of both slough and biofilm, and a number of methods are available to achieve this, including surgical/sharp and mechanical debridement. Developments have led to products indicated for debridement of wounds, including a sterile pad consisting of monofilament fibres. Our aim is to examine the effectiveness of a monofilament wound debridement pad (WDP), Debrisoft. METHOD: We assessed the WDP, in laboratory tests, for the removal of mature biofilm from porcine dermal tissue in an ex vivo model, and the clinical management of sloughy wounds that would benefit from debridement. We used the UPPER score to determine the superficial infection status. RESULTS: The WDP was effective in removing biofilm from porcine dermal tissue. A case series of 10 patients with chronic wounds suggested that the WDP was beneficial in the removal of slough. All chronic wounds had slough and were cleaned weekly, for four weeks, using the MDP to achieve improved healing and a clean wound bed. The average wound size decreased from 8.09cm2 at baseline to 2.3cm2 at week four, with three wounds healed completely. Exudate was reduced, and the UPPER score improved in every patient. CONCLUSION: These results indicate that the WDP effectively debrides biofilm and slough, and contributes to care that follows the principles of wound bed preparation and BBWC.

The characteristic clinical signs of chronic wounds, which remain in a state of prolonged inflammation, include increased production of devitalised tissue and exudate, pain and malodour. The presence of necrotic tissue, slough and copious exudate encourages microbial proliferation, potentially resulting in planktonic and/or biofilm infection. For patients, the consequences can include leakage of exudate, pain and reduced mobility, which can impair their ability to socialise and perform activities of daily living. This can severely reduce their quality of life and wellbeing. Concentrated surfactant-based gels (Plurogel and Plurogel SSD) are used in wound cleansing to help manage devitalised tissue. In vitro studies indicate they can sequester planktonic microbes and biofilm from the wound bed, although there is, limited clinical evidence to support this. A group of health professionals who have used this concentrated surfactant gel, in combination with standard care, in their clinical practice for several years recently met at a closed panel session. Here, they present case studies where topical application of these gels resulted in positive clinical outcomes in previously long-standing recalcitrant wounds. In all cases, the reduction in inflammation and bioburden alleviated symptoms that previously severely impaired health-related quality of life and wellbeing.

Chronic wounds remain a significant clinical challenge both for those affected and for healthcare systems. The treatment is often comprised and complex. All patients should receive wound care that is integrated into a holistic approach involving local management that addresses the underlying etiology and provides for gold standard therapy to support healing, avoid complications and be more cost effective. There have been significant advances in medicine over the last few decades. The development of new technologies and therapeutics for the local treatment of wounds is also constantly increasing. To help standardize clinical practice with regard to the multitude of wound products, the M.O.I.S.T. concept was developed by a multidisciplinary expert group. The M stands for moisture balance, O for oxygen balance, I for infection control, S for supporting strategies, and T for tissue management. Since the M.O.I.S.T. concept, which originated in the German-speaking countries, is now intended to provide healthcare professionals with an adapted instrument to be used in clinical practice, and a recent update to the concept has been undertaken by a group of interdisciplinary experts to align it with international standards. The M.O.I.S.T. concept can now be used internationally both as an educational tool and for the practical implementation of modern local treatment concepts for patients with chronic wounds and can also be used in routine clinical practice.
RESUMEN
Significance: The Wound Healing Foundation recognized the need for consensus-based unbiased recommendations for the treatment of wounds. As a first step, a consensus on the treatment of chronic wounds was developed and published in 2022. The current publication on acute wounds represents the second step in this process. Acute wounds may result from any number of conditions, including burns, military and combat operations, and trauma to specific areas of the body. The management of acute wounds requires timely and evidence-driven intervention to achieve optimal clinical outcomes. This consensus statement provides the clinician with the necessary foundational approaches to the causes, diagnosis, and therapeutic management of acute wounds. Presented in a structured format, this is a useful guide for clinicians and learners in all patient care settings. Recent Advances: Recent advances in the management of acute wounds have centered on stabilization and treatment in the military and combat environment. Specifically, advancements in hemostasis, resuscitation, and the mitigation of infection risk through timely initiation of antibiotics and avoidance of high-pressure irrigation in contaminated soft tissue injury. Critical Issues: Critical issues include infection control, pain management, and the unique considerations for the management of acute wounds in pediatric patients. Future Directions: Future directions include new approaches to preventing the progression and conversion of burns through the use of specific gel formulations. Additionally, the use of three-dimensional bioprinting and photo-modulation for reconstruction is a promising area for continued discovery.
RESUMEN
Significance: Chronic venous disease (CVD) is prevalent in the aging population and leads to venous leg ulcers (VLUs). These wounds can last and recur for years, significantly impacting quality of life. A large body of literature exists on CVD and VLU diagnosis and treatment. Multiple algorithms, guidelines, and consensus documents have been published on this topic, highlighting the importance of this issue in clinical practice. However, these documents are not fully aligned with each other. Recent Advances: The latest update of the internationally used classification system for CVD was recently published. Our review aims to summarize the existing information to provide an educational tool for clinicians new to this topic, and to highlight the commonalities between the published recommendations. Critical issues: VLUs need to be treated with consideration for the extent of venous disease present in the patient. This requires a good understanding of the various components involved and the possible additional concomitant conditions by the first-line clinician who encounters the patient. A multidisciplinary team is necessary for a successful overall treatment plan, and this plan should be tailored to each patient's specific needs and lifestyle. Future Directions: Compression is still the mainstay of treatment for CVD and VLUs. Compression is needed long term, but it does not suffice by itself to prevent recurrences without interventional correction. Venous intervention should be offered early to prevent or slow disease progression and reduce recurrence.

Management of chronic wounds remains challenging in terms of prevalence and complexity. Considerable progress has been made in understanding the science of wound healing during the past decade, sparking volumes of publications and the development of hundreds of dressing and therapy options. There is a need for a simpli ed overview of evidence-based criteria to assist in the accurate diagnosis and appropriate management of chronic wounds in all care settings. An expert panel of 11 wound healing specialists experienced in various care settings convened to discuss best practices and recommended guidelines for managing major chronic wound types. Prior to the meeting, panel members reviewed 8 preselected peer-reviewed articles and 1 white paper containing treatment algorithms for all major chronic wound types. During the meeting, each panelist presented current evidence-based guidelines regarding a specific chronic wound type and case studies to illustrate concepts in the guidelines. This publication is a result of the panel discussion and presents an overview of literature- and experience- based criteria to help guide chronic wound diagnosis, assessment, treatment, and follow-up. A cycle of steps is presented as a framework to guide holistic care for all patients with chronic wounds, including de- hisced surgical wounds, diabetic foot ulcers, venous leg ulcers, arterial insu ciency ulcers, and pressure ulcers/injuries. Emphasis is placed on criteria to assist accurate diagnosis and dressing/therapy selection, holistic elements of patient and wound bed preparation, interventions to achieve patient adherence to a care plan, and follow-up to help prevent wound recurrence.

Care of chronic and stalled wounds is hampered by the lack of diagnostic tools to help direct clinicians to specific treatments or diagnose specific conditions. Studies have shown a correlation between high protease levels and nonhealing wounds; a diagnostic protease test is under development. Seven wound care experts (two podiatrists, two vascular surgeons, a physician expert in hyperbaric oxygen therapy, a physical therapist with a specialty in home health, and a registered nurse) met to reach consensus on several aspects about a point-of-care protease test. They agreed that although disease states interfere with wound healing, such states do not automatically mean that wound healing will be impaired or that the wound becomes stalled after inception; and that patient comorbidities, patient factors, patient medications, and the microenvironment of the wound all affect the risk of nonhealing. They also agreed that: 1) appropriate protease activity was important in healing, 2) measuring just one individual protease would be unlikely to be representative of the proteolytic environment of the wound, 3) no diagnostic or theranostic tests to detect high protease activity levels in a wound is currently available, and 4) the development of a simple, widely available protease diagnostic test could dramatically change the provision of care, especially in outpatient settings. If subsequent research confirms that high protease activity levels delay healing, confirmation that a stalled wound has high protease activity levels could better target protease-modulating therapies and improve outcomes. Extensive validation of a protease test will be necessary from proof-of-concept pilot studies to controlled clinical trials to demonstrate that use of the test improves outcomes of care.

Individuals with Bruton's X-linked agammaglobulinemia (XLA) inherit a defect in the Btk gene, critical for B-cell differentiation. As a result, there is an absence of mature B-cells in the peripheral circulation with a marked reduction in serum levels of all immunoglobulin subtypes, predisposing patients with XLA to recurrent bacterial infections. Btk also functions in myeloid and dendritic cells, specifically in Toll-like receptor (TLR) signaling. TLRs are important in the recognition of foreign pathogens and elaboration of cytokines, such as tumor necrosis factor alpha (TNF-α). This suggests that the pathophysiology of XLA involves additional and unexplored immune dysregulation. The coexistence of pyoderma gangrenosum (PG) in a patient with Bruton's XLA has been rarely reported. PG is an uncommon, ulcerating, neutrophilic dermatosis. Although its etiology is unknown, it is noninfectious and thought to involve abnormal immune and neutrophil responses. Anti-TNF agents have been effective in treating some patients with PG, suggesting TNF-α may play a role in the pathogenesis of PG. Here we report the association of PG and Bruton's XLA, and demonstrate the presence of TNF-α within the lesion of PG.
