Wound care in calciphylaxis remains poorly defined without evidence-based consensus on timing and technique of surgical intervention. We demonstrate that surgical debridement and subsequent wound closure are safe and effective in calciphylaxis and describe a systematic multidisciplinary approach to intervention. We retrospectively reviewed a cohort of patients with calciphylaxis at our institution. Those who underwent surgical debridement and wound closure were analysed with emphasis on wound healing, progression to amputation and mortality. Sixty-two patients with calciphylaxis underwent surgical debridement. Twenty patients had wound closure by skin grafting, five were excised with primary wound closure, and 37 were debrided and allowed to heal by secondary intention. There were excellent rates of healing in all groups, and no patients demonstrated wound progression or new lesions following operative intervention. Surgical debridement and wound closure are safe and effective in treating wounds related to calciphylaxis.
The financial burden of diabetes-related foot disease (DFD) in Australia remains inadequately understood. This study aimed to explore the direct costs and resource utilisation associated with DFD management, incorporating insights from healthcare professionals actively involved in the treatment of individuals with DFD. A three-step approach informed the economic evaluation. First, a systematic review identified existing Australian cost data. Second, semi-structured interviews with healthcare professionals generated estimates of resource utilisation and addressed data source gaps. Third, a Markov model evaluated the costs of DFD management at both the individual and health system levels. The model included direct costs related to hospital admissions, outpatient/community visits, medications, diagnostics, wound care, offloading devices and amputation-related expenses. The average annual cost per patient for DFD management was AUD $44 691. The primary cost drivers were hospital admissions ($21 566), outpatient/community visits ($14 212) and wound debridement ($5918). The total cost to the Australian healthcare system in 2026 is estimated at AUD $3.08 billion, with projections reaching AUD $3.81 billion by 2030. This study provides essential cost estimates for DFD management at both the individual and health system levels, offering critical insights for policymakers seeking to optimise service delivery and improve patient outcomes in Australia.
Chronic wounds present a significant challenge to society and have a negative impact on the quality of life and daily activities of patients. This review aimed to identify the cost-effectiveness of the currently used care alternatives for the treatment of chronic wounds. This study serves to identify cost-effectiveness boundaries and provide a basis for determining the cost-effectiveness of the proposed care alternatives. A systematic literature search was conducted in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Articles published on Web of Science and PubMed from June 2013 to June 2023 were included. A comparative analysis was performed using the data adjusted for inflation and transformed for the same time horizon. The median time to heal was approximately 2.5 months in the first quartile of studies ending at 1.3 months and the third quartile ending at 3.7 months. The average cost of complete chronic wound healing for all care alternatives in the study sample was $6435, with a median cost of $5814. This systematic review covers a diverse range of treatment alternatives, their health effects and costs and highlights the complex landscape of cost-effectiveness in the treatment of chronic wounds.

Cognitive impairment is associated with people with diabetes-related foot ulcers (DFU). However, it is unclear if cognitive impairment is associated with the ulcer itself or other co-existing diabetes-related complications such as peripheral neuropathy. We aimed to investigate cognition in people with diabetes-related peripheral neuropathy and compare those with DFUs to those without DFUs. In this age- and sex-matched, multicentre, case-control, observational study of 89 participants with Type 2 diabetes and peripheral neuropathy, we compared 49 participants with DFUs (cases) to 40 without DFUs (controls). Global cognition scores were assessed using the Montreal Cognitive Assessment tool. Participants with DFUs had similar characteristics to those without DFUs (all, p > 0.05), except for lower body mass index (p = 0.028). Participants with active DFUs had significantly lower global cognition scores compared to those without DFUs (median [IQR] 24.0 [21.0–25.0], 26.0 [24.0–28.0]; p < 0.001). After adjusting for other diabetes-related complications, lower global cognition was independently associated with a DFU, peripheral artery disease, lower physical activity and no family history of diabetes (all, p ≤ 0.019). People with DFUs had lower cognitive scores than those without DFUs, suggesting that the DFU itself is independently associated with cognitive impairment. Future studies should explore causal pathways and targeted management strategies.
Keloids are chronic fibroproliferative skin disorders with high recurrence rates and limited treatment options, yet reliable diagnostic biomarkers are lacking. Current classification systems rely heavily on clinical observation, underscoring the need for objective, noninvasive tools. In this exploratory study, serum-based 1H nuclear magnetic resonance (NMR) measurement combined with short-time Fourier transform (STFT) for time-frequency analysis was performed, followed by principal component analysis (PCA), to investigate potential patient subgroups. Serum samples from 29 patients were analysed and PC1 scores suggested two potential patient subgroups. Retrospective analysis showed that these subgroups differed primarily in keloid aetiology: one group predominantly included cases arising from unclear or minimal causes (e.g., acne, folliculitis), whereas the other comprised cases following clear traumatic events (e.g., surgery). Although most clinical variables showed no significant differences, significant differences in aetiology and Japan Scar Workshop Scar Scale (JSS) scores support the biological relevance of this separation of subgroups. These findings suggest that the time-frequency features of NMR signals from serum samples capture systemic characteristics associated with keloid pathophysiology. If validated in larger cohorts, this approach may serve as a noninvasive adjunct to clinical assessment and lay the foundation for objective patient stratification and precision-guided treatment strategies.
Pressure ulcers (PUs) (also termed pressure injuries [PIs]) remain a major patient safety issue, particularly in critical care and other high-risk healthcare settings. Nurses are central to PUs/PIs prevention; however, deficiencies in knowledge, attitudes, and preventive practices among nursing staff may negatively affect patient outcomes. To systematically synthesise global evidence on nurses' knowledge, attitudes, and practices related to PUs/PIs prevention, and to identify factors influencing preventive performance. A systematic review was conducted in accordance with PRISMA guidelines. Electronic databases including PubMed, CINAHL, EBSCO, MEDLINE, PsycINFO, and Springer were searched for studies published between 2011 and 2025. Eligible studies were primary research articles examining registered nurses' knowledge, attitudes, and/or practices regarding PUs/PIs prevention, using cross-sectional, observational, or non-experimental designs. Data extraction focused on study characteristics, settings, samples, assessment instruments, and key outcomes related to knowledge, attitudes, and preventive practices. Due to methodological heterogeneity, a narrative synthesis was performed. Twenty-nine studies from diverse geographical regions were included, with sample sizes ranging from 28 to 950 nurses. Overall, nurses' knowledge of PUs/PIs prevention was frequently inadequate, particularly in prevention-specific domains. In contrast, attitudes toward prevention were generally positive across studies. Preventive practices, however, were often suboptimal. Commonly reported barriers included staff shortages, high workload, limited resources, and insufficient institutional support. Higher educational attainment, specialised clinical experience, recent training, and professional seniority were consistently associated with better knowledge, more positive attitudes, and improved preventive practices. Although nurses generally demonstrate positive attitudes toward PUs/PIs prevention, persistent gaps in knowledge and practice remain. These findings underscore the need for structured education programmes, simulation-based training, and strengthened organisational support to enhance adherence to evidence-based prevention strategies. Future research should employ experimental and longitudinal designs, standardised measurement tools, and broader international representation to support sustainable improvements in PUs/PIs prevention and patient safety.
Thromboangiitis obliterans (TAO) is a rare, tobacco-associated vasculitis that primarily affects the distal extremities of young males. In advanced stages, it often leads to chronic limb ischemia with ischemic ulceration, culminating in amputation. Data on risk factors for reamputation in this population remain limited. This study aimed to identify clinical, radiological and microbiological predictors of reamputation in patients with TAO-related foot ulcers undergoing amputation. A retrospective cohort study was conducted on 25 patients (31 limbs) with Fontaine stage IV TAO ulcers who underwent lower extremity amputation between January 2021 and December 2024. Patients were stratified into two groups based on whether they underwent repeat amputation (Group 1) or a single procedure (Group 2). Preoperative magnetic resonance imaging, intraoperative tissue cultures and laboratory data were evaluated. Smoking status, hospitalisation metrics and adjunctive therapies were recorded. Statistical analysis included Mann–Whitney U, Fisher's exact test, ROC curve analysis and multivariate logistic regression. Seventeen limbs required reamputation. Persistent smoking was observed in 100% of Group 1 compared with 58.4% of Group 2 (p = 0.015). Positive intraoperative cultures were significantly more frequent in Group 1 (64.7% vs. 21.4%; p = 0.029), with all multidrug-resistant organisms confined to this group. Length of hospital stay was significantly longer in Group 1 (25.2 ± 6.4 vs. 15.8 ± 5.3 days; p = 0.001). ROC analysis identified > 19 days of hospitalisation as a threshold for reamputation risk (AUC = 0.781; p = 0.018). Multivariate analysis identified three independent predictors of reamputation: persistent smoking (OR: 5.2, 95% CI: 1.2–22.8; p = 0.015), positive intraoperative culture (OR: 4.7, 95% CI: 1.1–20.1; p = 0.041), and hospitalisation longer than 19 days (OR: 6.5, 95% CI: 1.4–29.4; p = 0.018). Reamputation in advanced-stage TAO is strongly associated with modifiable factors, particularly ongoing tobacco use, Gram-negative infection and prolonged hospital stay. Early identification and targeted intervention addressing these variables may improve limb preservation outcomes in this high-risk population.
Surgical site infections (SSI) in vascular surgery have a huge impact on patients’ morbidity and mortality and healthcare systems worldwide. Dialkylcarbamoylchoride (DACC) is a synthetically produced material that can irreversibly bind and inactivate bacteria that exhibit cell-surface hydrophobicity (CSH). The DACC in the Reduction of Surgical Site Infection (DRESSINg) trial is a multicentre randomised controlled trial which aims to assess the effectiveness of DACC-coated post-operative dressings in the prevention of SSI in vascular surgery. Seven hundred and eighteen participants undergoing clean or clean-contaminated lower limb vascular surgery will be randomised in a 1:1 ratio to either DACC-coated dressings or standard dressings for their postoperative wounds. The primary outcome is the incidence of SSI defined by the Centers for Disease Control and Prevention (CDC) criteria or total ASEPSIS score of 21 or more within 30 days of surgery. The secondary outcomes include satisfactory wound healing with a total ASEPSIS score of 10 or less, quality of life pre and post surgery, Bluebelle wound healing scores, resource use and financial (£), and environmental (KgCO2e) cost analyses. This multicentre randomised controlled trial will provide level 1 evidence on the effectiveness of preventing SSI in lower limb vascular surgery.
Pressure injuries present significant challenges in clinical care, leading to severe complications such as infection, pain and delayed wound healing. They are a common chronic wound that contribute to increased morbidity, prolonged hospital stays and substantial healthcare costs. Despite national efforts to enhance chronic wound management, development of optimal treatment strategies remains a priority. The Pressure Injury Treatment Advisory (PITA) Quick Guide was developed to provide an evidence-based guide to support clinicians in pressure injury management. A survey was conducted to evaluate clinician perspectives on the usability and practicality of the Guide in acute care, residential aged care and community settings. A post-test survey was conducted on a convenience sample of healthcare professionals from three healthcare settings across metropolitan, regional and rural Australia. The survey included 5-point Likert-scale items assessing ease of use, effectiveness and integration with workflows. Three hundred and two responses were received (66.7% response rate). Clinicians expressed overwhelmingly positive perceptions, with over 95% agreeing or strongly agreeing on the guide's utility and effectiveness. No respondents strongly disagreed with any item. Residential aged care and rural clinicians rated the tool slightly higher than acute care and medical clinicians. The PITA Quick Guide was well-received across all settings, demonstrating strong potential to enhance evidence-based pressure injury management.
Necrotising fasciitis (NF) is a rapidly progressing, life-threatening infection with mortality rates that are exceedingly high. Despite the notably high risks of developing NF in patients with diabetes mellitus (DM), factors associated with mortality in this population are poorly understood. Therefore, to determine at-risk patients and to improve overall clinical outcomes via hastening management, the objective of this systematic review is to determine what factors are associated with mortality for diabetic patients with NF. This systematic review followed the PRISMA guidelines. Patient data pertaining to outcomes and surgical management were extracted, and mortality rates were evaluated. Studies were assessed for quality using the Alberta Heritage Foundation for Medical Research (AHFMR) and Risk of Bias tool. A total of 25 studies were reviewed, covering 7879 patients with NF and DM with a 23.5% mortality rate. The most prevalent comorbidities among those who died included chronic kidney disease (15.95%), hypertension (9.42%) and obesity (9.02%). While limbs were the most common location for the disease, NF in the trunk and groin regions showed the highest mortality rates at 62.07%. Among those who died, common complications were acute renal failure (13.41%), pulmonary issues (20.41%) and septicaemia (12.80%). Mortality rates by surgical management were fasciotomy (42.9%), surgical debridement (40.68%) and amputation (9.09%). Mortality was comparable between patients with NF and DM (23.54%) and those with NF alone (23.61%). Although DM may not independently increase mortality, it can worsen outcomes when combined with other comorbidities, indicating a need for clearer clinical guidance.
Preventing pressure injuries among nursing home residents is a significant challenge that necessitates understanding the barriers and facilitators from the perspective of staff. This qualitative study aimed to describe these factors within Sri Lankan nursing homes. Semi-structured interviews were conducted with 15 nursing home staff members from nine nursing homes in and near the Colombo district, Sri Lanka. The study was informed by the capability, opportunity, motivation, and behaviour model that guided both data collection and analysis. Data were analysed using content analysis. Using deductive coding based on capability, opportunity, and motivation, followed by inductive analysis, four primary categories emerged: focusing on skincare is foundational for pressure injury prevention, pressure injury knowledge is critical for prevention, pressure injury prevention is a low organisational priority, and overcoming challenges to enact pressure injury prevention. Key facilitators included access to skincare products, maintaining clean and dry skin, recognising risk factors, proactively managing risks, and understanding the broader implications of pressure injuries on residents and their families. Conversely, barriers encompassed limited training, varying staff support, inadequate resources, and the complexities of managing multiple tasks. This research highlights that enhancing knowledge and allocating resources effectively can improve the implementation of pressure injury prevention strategies in Sri Lankan nursing homes.
Open femoral vessel access is commonly performed in vascular surgery, but surgical site complications (SSCs) occur frequently. The aim of this study is to evaluate the incidence and identify potential risk factors by applying a new standardised definition and grading of various types of groin wound complications. This retrospective analysis includes 201 consecutive patients with 219 vertical groin incisions to expose the femoral vessels for different vascular interventions. A prophylactic drain was placed intraoperatively in almost all incisions (91%). Groin SSCs were defined and graded into four categories according to a modified Clavien-Dindo classification. Potential risk factors were evaluated using univariable analysis. For multivariable analysis, a multiple logistic regression was performed. Cutoff values were determined through ROC analysis. According to the proposed definition, regular postoperative course grade 0 (no SSC) occurred in 163 patients (74.4%), grade 1 (minor SSC) in 10 (4.6%), grade 2 (moderate SSC) in 14 (6.4%), and grade 3/4 (major or life-threatening SSC) in 32 (14.6%) incisions. The incidence of clinically relevant SSCs (grade 2–4) was 21%. Drainage volume was an independent parameter that predicted relevant SSCs with a threshold value of 70 mL/24 h on postoperative day 4 (sensitivity 100%; specificity 67%; AUC = 0.835; p = 0.0004). Groin wound complications following vascular procedures are common. Lymphatic leakage appears to be the most significant, potentially preventable condition associated with relevant SSCs. Prophylactic or early therapeutic interventions should focus on reducing lymphatic morbidity.
Needling therapy may be a novel alternative therapeutic intervention for burn injuries and related complications. This scoping review aimed to comprehensively evaluate the evidence status of needling therapy for burns and their complications. Studies on needling therapy for burns and related complications were retrieved from inception to 1st June 2024. Nine databases (MEDLINE, Embase, CENTRAL, CNKI, CiNii, RISS, KISS, DBpia and OASIS) were searched without any language or study-type restrictions. The study design, details of the needling therapy, and results of needling for burn injuries (or related complications) were evaluated. Of the 1475 articles screened, 46 studies (comprising 16 experimental studies, 12 case studies, four observational studies, 13 randomised controlled trials, and one systematic review) were included in the final analysis. Most studies (71.7%) investigated the acute-phase burn wound healing process, while the remaining studies (28.3%) focused on the modulation of burn-related complications. Experimental studies demonstrated that needling therapy activates phases of the wound healing process including the inflammation, proliferation, and remodelling phases and modulates the cholinergic anti-inflammatory response in burn-related acute symptoms. Clinical studies exhibited a significant heterogeneity regarding treatment period, patient population, and needling type across different study designs. Experimental studies have primarily focused on the wound healing process itself, whereas clinical studies have investigated short-term outcomes related to burn complications, with great heterogeneity observed in the methods of needling employed. Further studies are required to strengthen research gaps between experimental and clinical research, with proper treatment and evaluation periods to demonstrate the effectiveness of needling therapy for burns and associated complications.

The aim in this human trial is to compare the efficacy and safety of polygalacturonic–caprylic acid (PG–CAP) ointment to MediHoney in chronic wounds at three international medical centres. In this prospective open-label study, patients with chronic full-thickness wounds were randomised to daily treatment with PG–CAP ointment or MediHoney. Assessments were obtained weekly for 6 weeks. The validated Pressure Ulcer Scale for Healing (PUSH) score was used to track healing. Efficacies were compared using the Wilcoxon rank-sum test for continuous variables and chi-square or Fisher's exact test for categorical variables. Twenty-six patients with chronic wounds were included. Baseline characteristics were comparable between the groups; however, the history of diabetes mellitus was higher in the PG–CAP group (p = 0.011). All 13 PG–CAP patients showed improvement (100%), compared to only 69% of the 13 MediHoney patients (p = 0.023). Half of the failures in the MediHoney arm were associated with death (15%). No failures, adverse events or deaths occurred in the PG–CAP arm. PG–CAP wound ointment is a novel combination of two plant-based compounds that pose minimal risk of promoting antimicrobial resistance, was highly effective for eradicating wound-pathogen biofilms in vitro and promoted chronic wound healing in vivo with minimal inflammatory reactions. Our findings support PG–CAP as safe, noninferior and possibly more effective than MediHoney in healing chronic contaminated wounds.
Assessing and treating a patient's wound is something that every medical student may be faced with from day one of their postgraduate clinical career, regardless of their chosen field of specialisation. This includes acute or post-surgical wounds as well as chronic wounds. In contrast, learning content concerning wound care is currently underrepresented in medical school curricula, although there are many possible topics and options to incorporate this subject into medical teaching. As a first step in curriculum development, this study provides a comprehensive yet clinically relevant catalogue of possible learning objectives for medical students in wound care. An interprofessional and interdisciplinary group of wound care experts collected a first draft of learning objectives. Then a group of clinicians from 16 different medical specialties was consulted to additionally rate the relevance of each proposed learning objective. By this approach, a consensus catalogue of 32 relevant learning objectives in wound care for medical students was developed. Furthermore, varying perspectives of experts and clinicians on wound care topics and their relevance for medical students were identified. The findings of this study will facilitate future discussions about implementation of wound care content into medical curricula.
The treatment of chronic wounds in the Aged is often difficult. Masquelet technique is used for the treatment of infected large segmental bone defects as it provides an adequate blood supply for bone and soft tissue reconstruction. In this study, a two-stage wound management strategy was used, consisting of covering the initial wound with bone cement and skin grafting under induced membranes. From September 2020 to September 2022, 20 Aged patients with chronic refractory wounds of the lower extremities with exposed bone or tendons were recruited in the Department of Wound Repair Surgery of the Second Affiliated Hospital of Wenzhou Medical University. Each patient was reconstructed according to a two-stage process. In the first stage, while treating the patient's underlying disease, several debridements were first performed on the wound; subsequently, the Masquelet technique was applied to seal the wound with antibiotic bone cement. Four to 6 weeks later, the second stage was initiated—after confirming the sufficient formation of wound induced membranes, the bone cement was removed, and free skin grafts were finally used to cover the chronic refractory wounds on the extremities. The area of the defects ranged from 4.5 × 3.0 cm to 15.0 × 6.0 cm, and all soft tissue defects were associated with tendon or bone exposure. After the surgery, patients attended regular outpatient visits and were followed up by telephone and video to observe the healing of the wounds and whether there were any complications in the donor site. The Lower Extremity Function Scale (LEFS) score was used to evaluate the functional recovery of the lower extremities. We found that all implants survived without necrosis or infection. All 20 cases were followed up regularly after surgery for 3 to 12 months, with a mean of 7.6 months. In the first stage, Induced Membranes induction was performed 1–4 times, with an average of (1.3 ± 0.7) times, and in the second stage, free skin grafting was performed on the induction membrane, and all 20 cases of skin grafting survived without necrosis or infection; the appearance and texture of the skin in the grafted area were satisfactory, and the postoperative LEFS score was (69.83 ± 10.82). Finally, our strategy for the management of chronic refractory wounds in the Aged can achieve satisfactory clinical results, reduce surgical risk, be simple and reliable, and be an effective addition to the repair modality.
Patients with combat wounds and injuries, presented as extensive infected and purulent defects with antibiotic-resistant microflora, were treated in a surgical inpatient setting. Closure of extensive soft tissue defects of the limbs is possible using methods of plastic and reconstructive surgery and requires preoperative infection control. The lack of effect from preoperative treatment for purulent limb defects with antibiotic-resistant microflora leads to limb amputation. This clinical study proposes a method of treatment by hyperbaric oxygenation with an ozone-containing steam–water mixture as an anti-bacterial agent. Eighteen male patients, aged between 20 and 60 years, were categorised into three groups based on the time elapsed since the injury. All patients were treated using the proposed method. The high effectiveness of the proposed method was demonstrated in all groups and resulted in saving limbs from amputation, establishing suitable conditions for closing the soft tissue defects of the limbs and achieving significant progress in the recovery.
We aimed to investigate the learning needs of general practitioners and their preferences as regards the most appropriate teaching session for continuing medical education in wound management. A survey targeting general practitioners at the public health centres in the City of Helsinki. Twenty-seven general practitioners participated in the study. The majority (74.1%) had received education in medical school, 40.7% from wound care nurses, and 40.7% from colleagues. Participants felt the most competent in wound diagnosis (59.3%) and etiological tests (55.6%) and requested training in these topics (74.1% and 74.1%). A peer-led lecture (88.9%) was the most preferred technique, followed by lectures by wound care nurses (55.6%), an educational video (44.4%), a specialist-led lecture (37.0%), an interactive wound product session (29.6%), and digital self-study (29.6%). Wound diagnostics and etiological tests are recognised as crucial topics for continuing medical education. Peer-led lectures were preferred over other techniques; however, we observed varying preferences regarding the most optimal technique. Based on our results, we propose a half-day training including lectures, interactive and hands-on activities, and reflection, led by a peer and a wound care nurse with supporting video materials. Future studies could assess its impact on learning outcomes and wound care quality.
Self-treatment of benign symptoms using hot water bottles, steam inhalation or hot tea is common in households and poses risks of severe scald injuries. This study aims to investigate associated hazards and identify high-risk patient groups to facilitate targeted prevention. A retrospective, single-center descriptive study was conducted on adult burn patients with scald injuries from hot water bottles, steam inhalation or hot tea. Demographic information, injury mechanism and outcomes were analysed. A total of 43 patients (mean age: 37.5 years; female:male ratio 23:20) were included. Injuries were caused by hot water/tea (37.2%), steam (34.9%) and hot water bottles (27.9%). The average burned total body surface area (TBSA) was 4%, with 79.1% of injuries being superficial partial-thickness burns. Surgical intervention was required in 13.9% of cases. Hot water bottle injuries predominantly affected young females (75%, mean age 32.6 years), with a high incidence of genital burns (58.3%). Hot tea-related injuries were more frequent in older males (62.5%, mean age 41.6 years), involving greater TBSA (6.5%) and a higher necessity for skin grafting (18.8%). Common self-treatment strategies can cause serious scalds, particularly in specific demographic groups, thereby burdening healthcare systems. Awareness of these risks is pivotal for effective education and prevention.
