Soft silicone multi-layer dressings are commonly used for pressure ulcer (pressure injury) prevention, yet their effectiveness varies based on design, construct, and material properties. This study evaluated the protective efficacy of a new multi-layer dressing, ALLEVYN COMPLETE CARE (ACC, Smith & Nephew Limited), which incorporates an advanced structure facilitating the dissipation of shear forces through internal layer-on-layer frictional sliding within the dressing. Using a combination of experimental frictional energy absorber effectiveness (FEAE) testing and computational finite element modelling, we quantified the capacity of this dressing to mitigate strain and stress concentrations in the soft tissues of the supported posterior heel. The dressing demonstrated considerable frictional sliding between its adjacent layers, resulting in FEAE = 93% under simulated, clinically relevant usage conditions. This was associated with the dissipation of shear forces and alleviation of strain/stress concentrations in the skin and underlying soft tissues below the dressing. The dressing completely eliminated the stress and strain peaks at the top quartiles of the strain/stress domain (with reference to a no-dressing case). This work provided valuable insights into advanced testing methods and beneficial design principles for pressure ulcer prevention dressings. Earlier investigations concluded that a previous-generation ALLEVYN LIFE dressing achieved high levels of FEAE and thus provided protection. Our findings here establish that the next-generation dressing, ACC, demonstrates even greater protective capacity.
A novel advanced synthetic bioactive glass matrix was studied in patients with non-healing diabetic foot ulcers (DFUs). Bioactive glasses can be constructed to be biocompatible, with water-soluble materials in multiple geometries including fibre scaffolds that mimic the 3D architecture of a fibrin clot. In this trial, chronic, Wagner Grade 1 DFUs were randomised to receive borate-based bioactive glass Fibre Matrix (BBGFM) plus standard of care (SOC) therapy for 12 weeks or SOC alone. The primary study endpoint was the proportion of subjects that obtained complete wound closure at 12 weeks. Secondary endpoints included time to achieve complete wound closure at 12 weeks. In the modified intent-to-treat (mITT) analysis, 48% (32/67) treated with BBGFM plus SOC healed at 12 weeks compared to 24% (16/66) with SOC alone (p = 0.007). In the per protocol (PP) population, 73% (32/44) of subjects treated with BBGFM plus SOC healed versus 42% (16/38) in the SOC group (p = 0.007). Based on the success of this trial, BBGFM demonstrates faster healing of DFUs compared to SOC and should be considered in the treatment armamentarium for Wagner Grade 1 DFUs. Future trials should investigate the use of BBGFM for healing deeper chronic DFUs, other wound aetiologies, or complex surgical wounds.
Limited evidence exists regarding the effectiveness of learning approaches in supporting interprofessional wound care education transnationally. The aim of this pilot study was to explore the feasibility and preliminary impact of an international, online interprofessional masterclass in supporting baccalaureate health students' learning about wound care. Data were collected using multiple methods including quantitative survey, qualitative focus groups, and interviews with baccalaureate nursing, pharmacy, dietetics, podiatry and paramedicine students from two universities based in Australia and Northern Ireland. A retrospective pre-test design was used. A survey retrospectively assessed students' self-reported confidence and understanding before and after the masterclass, while qualitative methods explored students' experiences of interprofessional learning and wound care. Self-reported improvements in students' understanding of wound assessment and management, as well as heightened awareness of interprofessional contributions to patient care indicated the potential value of this interprofessional and international collaboration in supporting wound care education. Qualitative analysis identified four themes: recognising a wound is a person's wound; comparing international healthcare practices; fostering learner engagement; interprofessional recognition, acknowledgment, and understanding of each profession's roles, contributions and expertise. This pilot study has highlighted key issues to be addressed in future research examining the impact of a collaborative online international initiative on baccalaureate students' interprofessional learning about wound care.
Wound care remains a high-priority area for improvement in the Canadian health care system. Older adults aged 65 and older are disproportionately affected by chronic and non-healing wounds and often experience multiple co-morbid conditions, challenges which can be further complicated by living in rural and northern areas. A workshop-based multi-methods study was conducted to describe rural and northern perspectives on opportunities and feasibility to implement innovative wound care technologies. Each workshop included pre- and post- workshop surveys, a live demonstration of Swift Skin and Wound, a Q&A session, and facilitated discussion exploring the technology's feasibility, usability, and accessibility in northern and rural care contexts. Participants who volunteered for the study included care staff and healthcare executives (N = 11), described their perspectives on implementing AI-driven digital wound care management solutions with a focus on integration into health care settings. Three themes were identified including: confidence and optimism in improving wound care management, recognition of the superiority of AI-driven digital wound care solutions over current practices, and the importance of adaptable change processes for successful adoption. While generalizability may be limited, findings suggest that adopting AI-driven wound care tools could improve wound assessment accuracy and streamline care for aging populations in rural and northern areas.
Chronic wounds pose a public health challenge, with community pharmacists increasingly recognised for their potential role in wound care. Since all chronic wounds originate from acute wounds, pharmacists can play a proactive role in preventing chronicity. Assessing pharmacy staff's wound care knowledge is essential as initiatives to enhance their involvement are underway in Australia. This study aimed to assess wound care knowledge among pharmacists and non-pharmacist staff in Australian community pharmacies. A national cross-sectional electronic survey was conducted between January and August 2022. Developed with multidisciplinary experts, it assessed understanding of wound healing, referral protocols, wound identification, management, and dressing selection. Descriptive and content analyses were performed, and multivariate linear regression identified predictors of knowledge scores. Of 120 responses, 70% were pharmacists, 14% non-pharmacist staff, and 16% unspecified. The median knowledge score was 27 out of 37 (IQR = 21, 30; range = 5–37). Profession, experience, and prior training were significant predictors of higher scores (p < 0.001, R 2 = 0.347). Dressing knowledge was weakest, with only 10 out of 103 respondents (9.7%) correctly identifying all types and applications. Critical knowledge gaps underscore the need for targeted educational interventions for pharmacy staff.
Animal bites, primarily from dogs and cats, pose a significant threat, especially to children. Wound infections are common complications caused by bacterial flora in the animal's mouth, making surgical debridement and delayed primary closure the standard treatment. However, recent studies reported no increased infection rates with primary closure compared to delayed closure after adequate debridement, particularly for facial wounds. Primary closure offers better cosmetic and functional outcomes. This study presents a case series to guide decision-making on primary suturing versus leaving wounds exposed. Thirty patients with animal bites underwent surgery, including 23 dog bites and seven cat bites. Eight patients with deep facial lacerations from dog bites received immediate debridement and primary closure with epidermal and subcutaneous sutures. None developed infections, and the cosmetic results were excellent. In contrast, all seven cat bite wounds and nine infected dog bite wounds involved high-risk factors, such as puncture wounds, hand injuries or diabetes. For high-risk wounds, early debridement and leaving the wound open after initial treatment proved effective. Primary repair of facial dog bite injuries, even complex ones, is safe and yields good aesthetic outcomes. For high-risk wounds, leaving them open after debridement is recommended to minimise infection risks.
Pressure injuries (PIs) remain a problem for patient safety and the sustainability of healthcare systems. Difficulties persist in their assessment, prevention and monitoring by multidisciplinary teams. International recommendations point to this problem as a priority area for resolution in terms of patient safety. Research on the subject has been positive, resulting in several guidelines for clinical practice, but professionals' adherence remains below what is expected for their implementation. This scoping review aimed to identify interventions that increase multidisciplinary teams' adherence to the prevention and management of PIs between hospitals and the communities. The search was carried out in the MEDLINE (via PubMed), CINAHL, Scopus, Web of Science, JBI, Cochrane and grey literature databases by two independent reviewers, and led to the identification of 16 articles that met the eligibility criteria and made it possible to answer the research question. Strategies to improve adherence by health professionals include the creation and training of multidisciplinary teams, the implementation of new risk assessment models, Wound Boards, injury prevention reminders, video consultation apps, multidisciplinary rounds, documentation and recording. No studies were identified that assessed staff adherence to interventions aimed at preventing and managing PIs in the continuum between hospitals and communities, which is suggestive of the need for further research in this area.
Annually, 49 million people worldwide are impacted by lower extremity ulcers (LEUs). Diabetic foot ulcers (DFUs) and venous leg ulcers (VLUs) are the most common LEUs. Negative pressure wound therapy (NPWT) has emerged as an effective intervention for complex wounds, offering numerous favourable wound healing outcomes. The objective of this study was to evaluate the effectiveness of single-use NPWT (sNPWT) versus traditional NPWT (tNPWT) for wound closure in LEUs. Real-world data was obtained from the US-based Net Health outpatient database between January 2014 and October 2020 and included patients with LEUs (DFU or VLU) who had been treated with sNPWT or tNPWT. The rate of wound closure and time to wound closure were selected as endpoints. The wound closure rate was significantly higher for all LEUs (p = 0.039), VLUs alone (p = 0.003) and there was no difference for DFU (p = 0.90) that were treated with sNPWT versus tNPWT. The median time to wound closure was significantly shorter for sNPWT (114 days) compared to tNPWT (140 days, p < 0.01). Using sNPWT was associated with significantly higher wound closure rates and shorter time to wound closure. The results provide supportive evidence for using sNPWT for LEUs, demonstrating the opportunity to directly decrease the clinical burden of LEUs on patients. Subgroup analysis revealed a significant difference in wound closure rates for VLU, while no significant difference was observed for DFU. The overall LEU findings may be attributed to differences in the mechanisms of action between the two devices.
Wound care education is underrepresented in medical students' curricula. This scoping review aims to provide an overview of the published literature on educational methods and interventions used for chronic wound care education, specifically for medical students. A five-step framework for scoping reviews was used and includes a specific research question, identification of relevant literature, selection of studies, extraction of data and synthesis of the results. In total, six electronic databases (PubMed, Cochrane Library, Embase (Ovid), Web of Science, Scopus and APA PsychInfo) were searched with pre-defined search terms. The selection and evaluation of studies were conducted in a blinded review by three independent reviewers. The review was carried out in accordance with the PRISMA-ScR checklist for scoping reviews. We identified nine suitable studies regarding educational interventions for medical students in wound care. The included papers showed a broad variety of educational approaches, such as online learning tools or hands-on skills training. The implemented interventions had a positive effect on the students' wound care knowledge and their ability to perform wound care-related clinical skills. There is no comparison of the effectiveness of the different interventions, and it is not evaluated how effective they are compared to traditional lectures. There remains a need for more wound care education with a focus on the needs of medical students.
The aim of this study is to determine the incidence of pressure injuries (PI) and risk factors in neonatal patients followed up in the intensive care unit undergoing surgical intervention. Neonates are recognised as a patient population at high risk of pressure injury. Although the incidence of PI in hospitalised neonates is high, epidemiological studies on postoperative PI and affecting factors in hospitalised infants are scarce. A prospective, descriptive study. This study report follows the STROBE checklist. This study was conducted with 105 patients who received postoperative care in the neonatal intensive care unit of the gynaecology and obstetrics hospital of a province in XXX between November 2023 and January 2024. The Neonatal Descriptive Characteristics Form, Neonatal Q Pressure Ulcer Risk Assessment Scale, and the NPUAP Pressure Injury Classification System were used to collect data. The mean Neonatal Q Pressure Ulcer Risk Assessment Scale risk score of patients included in the research was 18.42, and 87% of those who developed PI had a risk of skin disorders. 21.9% of the neonatal patients developed PI, and 14.3% of them had Stage II PI. The majority of PI developed in the back region, and the rate of pressure injury was higher in those who underwent cardiopulmonary surgery longer than 3 h. It was determined that the use of medical equipment such as a central venous catheter, urinary catheter, drainage tube, and vasoactive drugs affected the rate of postoperative pressure injury development in neonates. The neonatals admitted in intensive care unit undergoing surgery suffered PIs. In the case of intensive care units, the incidence is even higher. The risk increases with cardiopulmonary surgery while the presence of medical devices is the main risk factor.
The Wound-QoL assesses patients' health-related quality of life. Quick and valid interpretation of the results is crucial, but no thresholds have yet been established. Additionally, counting top box responses might be a quick approximation to the Wound-QoL score itself. The aim of this study was to develop Wound-QoL bands (i.e., thresholds) and to analyse top box responses. Patients from European countries completed the Wound-QoL and a global question. We grouped patients' Wound-QoL scores and mapped these on the global question score. Upon this, we developed sets of Wound-QoL bands and calculated the weighted kappa (κ) coefficient of agreement for each set. Moreover, we analysed the correlation of the sum of top box responses with patients' Wound-QoL. The 305 patients (mean age: 68.5 years; 52.8% male) had most frequently leg ulcers (49.2%). The final set of Wound-QoL bands with the highest κ coefficient (0.564 and 0.550) was 0–0.25, not at all/rarely impaired; > 0.25 to 1, a little; > 1 to 2, moderately; > 2 to 3, quite a lot; > 3 to 4, very much. Top box responses showed strong correlation with the Wound-QoL scores (0.961–0.961). We are confident that the Wound-QoL bands will facilitate interpretation of Wound-QoL data in routine care as well as in research.
Skin allografts are essential in managing complex wounds, yet their availability is limited by low post-mortem donation rates. Skin harvested during body contouring surgeries offers a novel and sustainable source to expand tissue supply. We conducted a retrospective descriptive study at the Tarapacá Skin and Tissue Bank from January 2022 to December 2024. All donations from body contouring surgeries were processed as cryopreserved total skin allografts following national tissue banking standards. Variables included donor demographics, harvested area, units produced, microbiological results, and discard rates. To describe clinical performance, we present our group's initial clinical series of treated patients. From 248 living donors (mean age 41.3 years), 81 293 cm2 of skin generated 2050 units. The discard rate was 27%, mainly due to a storage failure and isolated microbial contamination. Clinically, all patients achieved complete initial graft take, followed by gradual necrotic eschar formation at an average of 21 days. Eschar removal revealed vital tissue firmly adhered to the recipient bed, rich in fibroblasts and neovascular structures. Subsequent management included either escharectomy with split-thickness autografting over the neodermis, or spontaneous eschar lysis and skin regeneration, with the graft functioning as a dermal regenerator. This model increases tissue availability while providing allografts with both coverage and dermal regenerative properties.
The opioid crisis has been exacerbated by xylazine, a veterinary sedative increasingly present in illicit drugs. Xylazine causes severe skin wounds that increase the risk of morbidity. Current wound classification systems fail to address the unique features of this injury, creating a need for a tailored assessment and treatment approach. We developed the HEAL-X classification system to standardise evaluation and treatment of xylazine-associated wounds. The system grades wounds using five criteria: History, Extent, Appearance, Location, and Xylazine-specific features. Grades range from 0 (normal skin) to 5 (underlying structure involvement). HEAL-X integrates principles from existing classifications while focusing on xylazine-specific pathology. This novel system was developed by an inter-disciplinary panel and requires empirical validation through clinical application and further research. HEAL-X provides a framework for grading xylazine-associated wounds, guiding treatment from lower-grade wounds to severe cases. This system aligns with the unique characteristics of xylazine wounds, offering a more tailored approach than any existing models individually. HEAL-X addresses a critical gap in managing xylazine-associated wounds. It offers a standardised tool to evaluate wound severity, guide treatment, and improve patient outcomes. As xylazine use rises and further research refines prognostic indicators and treatment outcomes, HEAL-X provides a framework on which to build.

The above article, published online on 26 May 2023 in Wiley Online Library (http://onlinelibrary.wiley.com/), has been retracted by agreement between the journal Editor in Chief, Professor Keith Harding; and John Wiley & Sons, Ltd. An investigation by the publisher found that the Methods section lacked appropriate detail and thus was not reproducible. In Section 2.1 Reference 5 was found to be irrelevant and did not support the statements regarding eligibility criteria. Additionally, the article states that they have performed a sensitivity analysis in Section 2.8, but the article does not include a sensitivity analysis. Additionally, the review found that the article contained significant textual overlap in the methods section between this article and other articles by different authors [1-3]. The authors responded to an inquiry by the publisher, but they were not able to provide a response to these concerns. As such, the retraction has been agreed to because the methodology contains missing information and is not reproducible. The authors stated that they agree to the retraction voluntarily.

Faecal contamination of sacral pressure ulcers occurs frequently, so, theoretically, faecal diversion using colostomies is a useful procedure. We retrospectively analysed the data of adult patients for whom colostomies were created to enhance wound healing and compared patients with sacral pressure ulcers who received colostomies and those who did not during the same period. Patients' characteristics analysed included age, gender, comorbidities, WBC count, serum CRP level and microbial profile (before creating colostomy). Additionally, we examined whether the wound was closed, the recurrence rate after wound closure, and mortality outcomes. Regression analysis indicated that colostomy creation was associated with fewer species of gut microbiota cultured and lower rates of wound dehiscence after closure; no association was found between colostomy and mortality. Colostomies help promote wound healing of sacral pressure ulcers after closure by eradicating wound infection, and do not increase patients' mortality rates.
Chronic and non-healing wounds are a global health issue with limited effective treatments. Wound care costs continue to rise, highlighting the need for new therapies. Medicinal plants, particularly African species, show promise for enhancing wound healing. This review analysed 93 studies and identified 37 relevant to wound healing, covering 39 plant species. Ten species were identified for their rich phytochemical content, specifically flavonoids, terpenoids, and alkaloids (plant-derived compounds). These compounds act synergistically, enhancing the wound healing process at each stage. Flavonoids reduce inflammation and support tissue turnover, while terpenoids enhance collagen production and wound closure. Alkaloids offer antimicrobial benefits and support wound contraction. Notable plants include Ageratum conyzoides and Aspilia africana (Asteraceae family); promoting haemostasis by lowering plasma fibrinogen and enhancing platelet-derived growth factors; Withania somnifera (Solanaceae); and Entada africana (Fabaceae), effectively regulating inflammation. In the proliferative phase, Ocimum gratissimum (Lamiaceae), Calendula officinalis (Asteraceae), and Centella asiatica (Apiaceae) although C. officinalis is native to Southern Europe, and C. asiatica an Asian-native; they are widely used in African traditional medicine and included here for their relevance in African wound healing practices; Justicia flava (Acanthaceae), Alternanthera sessilis (Amaranthaceae), and Acalypha indica (Euphorbiaceae); play key roles in enhancing collagen production, angiogenesis, and re-epithelialisation. This comprehensive analysis highlights the role of African medicinal plants in wound healing and their potential to improve wound care therapy.
