Abstract
Wound analytics, infection detection, and oxygenation measurement are the three critical prerequisites for appropriate wound care. Although devices that rapidly detect the above-mentioned parameters independently exist, there is no single point-of-care device that is enabled with all the three functionalities. Through this study, we are introducing and evaluating the performance of Illuminate Pro Max-a novel, rapid, hand-held non-contact, point-of-care multimodal imaging device that is equipped to measure the three wound assessment parameters. Here, a total of 60 diabetic foot ulcer patients were imaged using Illuminate Pro Max to detect bioburden and measure StO2 levels and wound dimensions (size and depth). The results were further evaluated against the current gold standard technique for each parameter, that is, culture test to detect bioburden, a transcutaneous oxygen pressure (TcPO2) measuring device-Perimed Periflux 5000 to measure oxygenation, and paper ruler to measure wound size. Culture tests reported 42 samples as infection-positive and 18 samples as infection-negative. On comparing with the culture report, the device showed 88% sensitivity and 86% PPV in detecting the bioburden. Wound dimensions (length and width) were comparable with the paper scale measurements. Wound depth was also reported by the device. The StO2 map generated by the device depicted the tissue oxygenation levels in various regions of the wound. In conclusion, this novel, comprehensive point-of-care multispectral imaging device can be an effective tool for rapid wound assessment which can help in prompt treatment.

Abstract
Age-related skin changes lead to increased susceptibility to skin damage and delayed wound healing, which is exacerbated by comorbidities such as cardiovascular disease and diabetes mellitus. In some cases, wound healing is not achievable or realistic and this needs to be reflected in the wound management plan. To improve outcomes and experience in older people presenting with wounds it is important to select wound management products that protect the wound bed and surrounding skin, minimise trauma, reduce symptoms and/or promote healing. This article explores how conducting holistic wound assessments, setting realistic treatment aims, and using wound management strategies tailored to each person's needs and wishes can have a positive effect on older people's quality of life.

Abstract
OBJECTIVE The effective assessment of wounds, both acute and hard-to-heal, is an important component in the delivery by wound care practitioners of efficacious wound care for patients. Improved wound diagnosis, optimising wound treatment regimens, and enhanced prevention of wounds aid in providing patients with a better quality of life (QoL). There is significant potential for the use of artificial intelligence (AI) in health-related areas such as wound care. However, AI-based systems remain to be developed to a point where they can be used clinically to deliver high-quality wound care. We have carried out a narrative review of the development and use of AI in the diagnosis, assessment and treatment of hard-to-heal wounds. We retrieved 145 articles from several online databases and other online resources, and 81 of them were included in this narrative review. Our review shows that AI application in wound care offers benefits in the assessment/diagnosis, monitoring and treatment of acute and hard-to-heal wounds. As well as offering patients the potential of improved QoL, AI may also enable better use of healthcare resources.

Abstract
Chronic limb-threatening ischemia (CLTI) represents one of the most severe forms of peripheral arterial disease implying impaired wound healing and tissue loss at the same time posing a significant impact on the quality of life of patients and a serious economic burden on healthcare systems around the world. A major challenge in the management of patients with CLTI is the validity and role of non-invasive hemodynamic parameters in assessing their clinical status before and after revascularization. Traditionally, the diagnosis of CLTI is routinely based on clinical symptoms and confirmed by measurements of non-invasive limb hemodynamics including ankle-brachial pressure index (ABPI) and toe-brachial pressure index (TBPI). However, whether these indices alone can provide definitive treatment or be used as adjunctive tool along with the implementation of novel techniques to help guide revascularization for CLI patients still remains unclear.

Abstract
PURPOSE Effective treatment of diabetic foot ulcers (DFUs) involves a multidisciplinary treatment plan to promote wound healing and prevent complications. Given the lack of consensus data on the factors affecting patient adherence, a systematic review was performed to identify and classify factors according to the WHO Dimensions of Adherence to Long-Term Therapies. METHODS Six hundred and forty-three articles from PubMed, Embase, and Scopus were reviewed. The inclusion criteria included qualitative and quantitative studies which discussed factors affecting patient adherence to DFU treatment, had study populations that comprised patients with either prior history of or existing DFU, and had either prior history of DFU treatment or were currently receiving treatment. Factors, and associated measures of adherence, were extracted and organized according to the WHO Dimensions of Adherence to Long-Term Therapies. RESULTS Seven quantitative and eight qualitative studies were included. Eleven patient-related factors, seven condition-related factors, three therapy-related factors, five socioeconomic factors, and five health system-related factors were investigated by the included studies. The largest proportion of factors studied was patient-related, such as patient insight on DFU treatment, patient motivation, and patient perception of DFU treatment. There was notable overlap in the range of discussed factors across various domains, in the socioeconomic (including social support, income, social and cultural acceptability of DFU therapy, cost) and therapy-related domains (including duration of treatment, offloading footwear, and reminder devices). Different studies found that specific factors, such as gender and patients having a low internal locus of control, had differing effects on adherence on different cohorts. CONCLUSION Current literature presents heterogeneous findings regarding factors affecting patient adherence. It would be useful for future studies to categorize factors as such to provide more comprehensive understanding and personalized care to patients. Further research can be done to explore how significant factors can be addressed universally across different cohort populations in different cultural and socioeconomic contexts.

Abstract
BACKGROUND Chronic wounds present significant challenges for patients and nursing care teams worldwide. Digital health tools offer potential for more standardised and efficient nursing care pathways but require further rigorous evaluation. OBJECTIVE This retrospective matched cohort study aimed to compare the impacts of a digital tracking application for wound documentation versus traditional manual nursing assessments. METHODS Data from 5236 patients with various wound types were analysed. Propensity score matching balanced groups, and bivariate tests, correlation analyses, linear regression, and Hayes' Process Macro Model 15 were utilised for a mediation-moderation model. RESULTS Digital wound tracking was associated with significantly shorter healing durations (15 vs. 35 days) and fewer clinic nursing visits (3 vs. 5.8 visits) compared to standard nursing monitoring. Digital tracking demonstrated improved wound size reduction over time. Laboratory values tested did not consistently predict healing outcomes. Digital tracking exhibited moderate negative correlations with the total number of nursing visits. Regression analysis identified wound complexity, hospitalizations, and initial wound size as clinical predictors for more nursing visits in patients with diabetes mellitus (p < .01). Digital tracking significantly reduced the number of associated nursing visits for patients with peripheral vascular disease. CONCLUSION These findings suggest that digital wound management may streamline nursing care and provide advantages, particularly for comorbid populations facing treatment burdens. REPORTING METHOD This study adhered to STROBE guidelines in reporting this observational research. RELEVANCE TO CLINICAL PRACTICE By streamlining documentation and potentially shortening healing times, digital wound tracking could help optimise nursing resources, enhance wound care standards, and improve patient experiences. This supports further exploration of digital health innovations to advance evidence-based nursing practice. PATIENT OR PUBLIC CONTRIBUTION This study involved retrospective analysis of existing patient records and did not directly include patients or the public in the design, conduct, or reporting of the research.

Abstract
Skin tears, defined as traumatic wounds caused by mechanical forces, can be debilitating for individuals, causing pain and reduced mobility. Although skin tears can develop throughout the lifespan, older age can make the skin increasingly susceptible to this type of injury. Studies have found wide variation in the incidence and prevalence of skin tears, in part because of suboptimal recognition and reporting practices among healthcare professionals. Effective prevention of skin tears requires a standardised approach to risk assessment, prevention, recognition and classification, such as that offered by the International Skin Tear Advisory Panel (ISTAP) best practice recommendations. This article examines the literature on the incidence, prevalence, prevention and recognition of skin tears, and outlines some of the ISTAP best practice recommendations on risk assessment, prevention and recognition. The authors also consider the need for patient and healthcare professional education to optimise the prevention of skin tears.

Abstract
OBJECTIVE To (i) quantitatively measure wound tension in experimental skin wounds using a newly developed wound tensiometer and (ii) establish reference values for primary skin wound closure in medium- and large-breed dogs. STUDY DESIGN Experimental cadaveric study. ANIMAL POPULATION Nineteen dogs of medium to large breeds (BW 20 to 40 kg). METHODS Elliptical skin wounds of different sizes were created on the chest and abdomen. The wounds were gradually enlarged. Experienced surgeons (ECVS diplomates or professors of small animal surgery) and inexperienced surgeons (1st year after graduation) independently assessed wound tension through manual manipulation and determined whether the wound could be closed without tension-relieving measures. In addition, wound tension was objectively quantified using a newly developed wound tensiometer. RESULTS The upper threshold for wound tension at which direct appositional wound closure was recommended by the experienced surgeons was 5.4 N, and the median minimal tension without recommendations for closure was 6.0 N. The data also demonstrate that wound tension and wound size do not necessarily correlate, and inexperienced surgeons need to develop a feel for wound tension. CONCLUSION The intraoperative use of the wound tensiometer, in combination with established cut-off values, might facilitate decision-making regarding primary wound closure. CLINICAL RELEVANCE The findings of this study provide evidence for the applicability of a wound tensiometer in guiding inexperienced surgeons in their choice of the skin wound closure method.

Abstract
A specific assessment tool is urgently needed to guide effective wound care for diabetic foot ulcers. However, the tool has not been available in Chinese. We aimed to culturally translate and verify the validity and reliability of the new Diabetic Foot Ulcer Assessment Scale (DFUAS). The original scale was translated into Chinese according to the Brislin guidelines. Patients satisfying the inclusion and exclusion criteria were recruited. Each of the included foot ulcers was evaluated independently by two wound care specialists using the new DFUAS and by the third wound care specialists at the same time using the Bates-Jensen Wound Assessment Tool according to per guidelines. 210 diabetic foot ulcers were included for data analysis. The S-CVI of the Chinese version of the DFUAS was 0.96, and the I-CVIs ranged from 0.89 to 0.98. The total Cronbach's Alpha of the scale was 0.709, and the corrected item-total correlation of the items ranged from 0.4 to 0.872. The DFUAS had high inter-observer reliability of 0.997, and there were weak, moderate, and strong correlations between each pair of the items. The Bland-Altman plots showed a good agreement between the scale and the Bates-Jensen Wound Assessment Tool. We concluded that the Chinese version of the DFUAS showed good validity and reliability and is a reliable instrument for the assessment of diabetic foot ulcers.

Abstract
Despite its increasing prevalence, severity, and mortality, Diabetic foot syndrome (DFS) still remains an unaddressed critical issue. The management of DFS is adequately performed only in few centers, and clinical outcomes vary, depending on the possibility of patients to access optimal standards of care. To focus on the critical aspects of the management of DFS in Italy with the purpose of suggesting arguments that might have a more general audience, to improve the quality of therapy and accessibility to optimal care, we have written this article.

Abstract
Non-optimal wound management and late referral to specialised units negatively impacts patient prognosis and quality of life, as well as healthcare costs. Healico is a new mobile application (app), created in the wound care field, in response to the challenges and difficulties encountered by health professionals (HPs) who deal with patients with wounds on a daily basis. This article aims to describe how this new app was developed, how it works, as well as the real-life clinical benefits and evidence supporting its use. The Healico App assists nurses, physicians and other HPs by: supporting a holistic approach to patient management; facilitating wound assessment and documentation, irrespective of where care is provided (primary, specialised or hospital services, in either public or private institutions); and supporting consistent and safe clinical practice, as well as reducing variation in care. It also provides a fast, fluid and secure communication channel, and effective coordination between HPs, supporting early interventions. The app has also been shown to improve therapeutic adherence of patients by promoting inclusive dialogue with them.

Abstract
OBJECTIVE The aim of this study was to measure wound pH, wound temperature and wound size together to gain further understanding of their impact as predictors of wound healing outcomes. METHOD This study employed a quantitative non-comparative, prospective, descriptive observational design. Participants with both acute and hard-to-heal (chronic) wounds were observed weekly for four weeks. Wound pH was measured using pH indicator strips, wound temperature was measured using an infrared camera and wound size was measured using the ruler method. RESULTS Most of the 97 participants (65%, n=63) were male; participant's ages ranged between 18 and 77 years (mean: 42±17.10. Most of the wounds observed were surgical 60%, (n=58) and 72% (n=70) of the wounds were classified as acute, with 28% (n=27) classified as hard-to-heal wounds. At baseline, there was no significant difference in pH between acute and hard-to-heal wounds; overall the mean pH was 8.34±0.32, mean temperature was 32.86±1.78°C) and mean wound area was 910.50±1132.30mm2. In week 4, mean pH was 7.71±1.11, mean temperature was 31.90±1.76°C and mean wound area was 339.90±511.70mm2. Over the study follow-up period, wound pH ranged from 5-9, from week 1 to week 4, mean pH reduced by 0.63 units from 8.34 to 7.71. Furthermore, there was a mean 3% reduction in wound temperature and a mean 62% reduction in wound size. CONCLUSION The study demonstrated that a reduction in pH and temperature was associated with increased wound healing as evidenced by a corresponding reduction in wound size. Thus, measuring pH and temperature in clinical practice may provide clinically meaningful data pertaining to wound status.

Abstract
The aim of this feasibility study was to investigate the impact of inflammation management on wound pH, temperature, and bacterial burden, using the principles of TIME and Wound Bed Preparation. A quantitative non-comparative, prospective, descriptive observational design. Following ethical approval, 26 participants with 27 wounds of varying aetiologies were observed twice weekly for 2 weeks. Wounds were treated with cleansing, repeated sharp debridement, and topical cadexomer iodine. Wound pH (pH indicator strips), temperature (infrared camera), bacterial burden (fluorescence imaging) and size (ruler method) was monitored at each visit. The mean age of all participants was 47 years (SD: 20.3 years), and 79% (n = 19) were male, and most wounds were acute (70%; n = 19) and included surgical and trauma wounds, the remaining (30%; n = 8) were chronic and included vascular ulcers and non-healing surgical wounds. Mean wound duration was 53.88 days (SD: 64.49 days). Over the follow up period, pH values ranged from 6 to 8.7, temperature (centre spot) ranged from 28.4°C to 36.4°C and there was an average 39% reduction in wound size. Inflammation management had a positive effect on pH, temperature, bacterial burden, and wound size. This study demonstrated that it was feasible to practice inflammation management using a structured approach to enhance wound outcomes.

Abstract
Maggot debridement therapy (MDT) has been used for years in the treatment of chronic wounds and necrotic tissues. We report a case of subtotally amputated third toe that was treated with MDT after reattachment and developing complete necrosis. The necrotic toe was replaced with viable tissue and the wound healed completely after 2 weeks of MDT application. This case points out the regenerative effects of MDT besides its mechanical debridement effect on the necrotic tissue.

Abstract
BACKGROUND Ulcer area is a critical parameter in diabetic foot ulcer assessment but existing methods have deficiencies for routine measurement. AIM We hypothesized that the Image J-based Computer Analysis method has a high level of agreement with the commonly used Maximum Length and Width and the Transparent Dressing-based Square Grid methods and aimed to test the consistency and verify the feasibility of the Image J-based Computer Analysis method in the routine assessment of ulcers. METHODS Outpatient attendees with diabetic foot ulcers at the Department of Endocrinology of Sun Yat-sen Memorial Hospital were enrolled between October 2020 and October 2021. The three methods sequentially assessed the area of 65 included ulcers. Results were analysed using one-way analysis of variance and Bland-Altman plots to perform consistency analysis. RESULTS The mean ± standard deviation ulcer area measured using the three methods were 14.79 ± 5.39, 14.35 ± 5.26, and 14.30 ± 5.26 cm2 , respectively. The measurement differences among the three groups or between any two were not statistically significant. Bland-Altman plots showed good consistency between the Image J-based Computer Analysis and the other two methods. CONCLUSION The Image J-based Computer Analysis method can be interchanged with the other methods to assess ulcer areas. It is freely accessible, accurate and home-operable, thus worth consideration by nurses for routine ulcer area assessment.

Abstract
Tetanus infection is caused by the Clostridium tetani bacterium, which can enter the body through a wound or puncture in the skin. Patients who present to an emergency department (ED) with a laceration, wound or bite require a risk assessment to determine whether the wound is clean, tetanus prone or high-risk tetanus prone. Those assessed as tetanus prone or high-risk tetanus prone, with an uncertain or inadequate immunisation history, should receive tetanus prophylaxis treatment. However, some patients receive this treatment unnecessarily. This article describes a service evaluation that explored whether practice in one ED was contributing to potentially avoidable tetanus prophylaxis treatment. The article outlines the results of a five-year retrospective database review, which determined that 18% of all tetanus prophylaxis treatments delivered in the ED during that period were unnecessary. The author makes some recommendations to improve practice.

Abstract
Exercise therapy helps improve glycaemic control and insulin sensitivity and may be relevant in treating patients with diabetic foot ulcers (DFUs). This study describes the development of a 12-week exercise therapy program for patients with DFUs and the preliminary feasibility of the program focusing on the program's inclusion, adherence, and safety. The development process is built on knowledge from a published systematic review on exercise for people with DFUs and a grounded theory study on the main concerns of people with DFUs regarding physical activity. The development involved doctors, wound care nurses, podiatrists, and feedback from patients and physical therapists using semi-structured interviews. The program was designed as a combination of aerobic and resistance training exercises. The aerobic exercise phase on the stationary bike of 30-minute duration was aimed at a moderate intensity. Resistance exercises were conducted with a 15-repetition maximum approach (four to five sets per trial) throughout the 12-week period. Three patients were included and received the exercise intervention. Except for recruitment and retention rates, acceptance levels were met for all other research progression criteria. Patients found the intervention relevant, wanted further guidance on continuing exercising, and would have liked the intervention closer to their home for example, a municipality setting. Although the exercise therapy program for patients with DFUs was developed in a thorough process with the inclusion of available evidence and the involvement of patients and other stakeholders conclusions on feasibility are limited due to the low recruitment rate. A reconsideration of the setting is needed in future exercise intervention studies.

Abstract
Background: Infection in the ulcerated foot is a foremost cause of morbidity, constituting the biggest proportion of hospitalization and amputation among patients with diabetic foot ulcers. Assessment of infection severity lays a foundation for making treatment decisions, for which the IDSA/IWGDF classification is recommended. Different factors may cause various severity of infection. However, few investigations have been conducted concerning factors associated with infection severity of diabetic foot ulcers. Objective: To investigate factors associated with infection severity of diabetic foot ulcers. Methods: This cross-sectional study involved 150 subjects hospitalized in the Department of Endocrinology of Sun Yat-sen Memorial Hospital in Guangdong Province between July 2020 and September 2021. The IDSA/IWGDF classification was adopted to assess ulcer infection severity. Demographic and disease information, laboratory reports, and ulcer assessment results were evaluated for an association with the infection severity. The generalized linear model was performed to conduct multivariate analyses of the factors associated with the severity of foot infection. Results: The prevalence of mild, moderate, and severe infected diabetic foot was 23.3%, 64.7% and 10.2%, respectively. The results of generalized linear models showed a correlation between Alb (OR = -1.74, 95%CI1.12-6.58, p = .023), CRP (OR = 2.13, 95%CI1.38-7.21, p = .014), PCT (OR = 2.01, 95%CI1.29-7.64, p = .013), microbial type (OR = 2.04, 95%CI1.43-7.83, p = .004) and ulcer infection severity. Conclusion: Alb, CRP, PCT and microbial type were among the factors influencing infection severity of diabetic foot ulcers.

Abstract
Medical devices such as peripheral intravenous cannulae (PIVC) are commonly used in the care of children across all hospital settings. However, the association between PIVC and the development of pressure injuries in this population became a concern on one Australian paediatric ward. A quality improvement project was conducted to reduce the incidence of pressure injuries in children caused by PIVCs. A tubular bandage and microfoam surgical tape were introduced to replace crepe bandage PIVC securement. At the same time, education was provided to alert nurses to medical device-related pressure injuries and the PIVC securement changes. The introduction of the tubular bandage and staff education improved skin inspections of PIVCs and decreased the incidence of pressure injuries from these devices.

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

Abstract
A wound can be defined as infected when the presence and subsequent proliferation of microorganisms leads to a local or systemic response in an individual. Wound infection is associated with delayed healing, wound chronicity, increased risk of hospital admission, loss of limb or digit and increased healthcare costs. The presence of biofilm is also recognised as a challenge in infected wounds and is associated with chronicity and delays in healing. Identifying and managing wound infection early can contribute to faster wound healing, thus reducing the risk of negative outcomes. This article details the pathophysiology, risk factors and signs and symptoms of wound infection. It also outlines various prevention and management options for wound infection.

Abstract
Background Skin ulcers are an important cause of morbidity and mortality everywhere in the world and occur due to several causes, including diabetes mellitus, peripheral neuropathy, immobility, pressure, arteriosclerosis, infections, and venous insufficiency. Ulcers are lesions that fail to undergo an orderly healing process and produce functional and anatomical integrity in the expected time. In most cases, the methods of analysis used nowadays are rudimentary, which leads to errors and the use of invasive and uncomfortable techniques on patients. There are many studies that use a convolutional neural network to classify the different tissues in a wound. To obtain good results, the network must be trained with a correctly labeled data set by an expert in wound assessment. Typically, it is difficult to label pixel by pixel using a professional photo editor software, as this requires extensive time and effort from a health professional. Objective The aim of this paper is to implement a new, fast, and accurate method of labeling wound samples for training a neural network to classify different tissues. Methods We developed a support tool and evaluated its accuracy and reliability. We also compared the support tool classification with a digital gold standard (labeling the data with an image editing software). Results The obtained comparison between the gold standard and the proposed method was 0.9789 for background, 0.9842 for intact skin, 0.8426 for granulation tissue, 0.9309 for slough, and 0.9871 for necrotic. The obtained speed on average was 2.6, compared to that of an advanced image editing user. Conclusions This method increases tagging speed on average compared to an advanced image editing user. This increase is greater with untrained users. The samples obtained with the new system are indistinguishable from the samples made with the gold standard.

Abstract
Preventing recurrent pressure ulcers is an important challenge in healthcare. One of the reasons for the high rate of recurrent pressure ulcers is the lack of assessment methods for their early detection. Therefore, this study aimed to determine the thermographic characteristics of the healed area and to consider the predictive validity of thermographic images for recurrent pressure ulcers within a 2-week period. This observational study was conducted at a long-term care facility in Japan between July 2017 and February 2019 among patients whose pressure ulcers had healed. Thermographic images of the healed area were recorded once a week until recurrence or until the end of the study. We enrolled 30 participants, among whom 8 developed recurrent pressure ulcers. The generalised estimation equation revealed that the thermographic finding of increased temperature at the healed area compared to that of the surrounding skin was significantly associated with recurrent pressure ulcers (odds ratio: 101.13, 95% confidence interval: 3.60-2840.77, p = .007); the sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio and negative likelihood ratio for recurrent pressure ulcers within 2 weeks were 0.80, 0.94, 0.62, 0.97, 12.9 and 0.2, respectively. Our thermographic findings revealed that the temperature of the healed area was higher than that of the surrounding skin; this could be a useful predictor of pressure ulcer recurrence within 2 weeks, even in the absence of macroscopic changes.

Abstract
An 84-year-old male patient with no known comorbidity was admitted to the emergency department with complaints of dyspnea and respiratory distress. The patient was referred to the COVID outpatient clinic, laboratory and radiology tests were performed. Thoracic CT scan of the patient showed large peripheral patchy ground glass densities observed in the lower lobes of both lungs. CT imaging findings were evaluated by an experienced radiologist and reported as COVID-19 pneumonia. The patient, who was self-isolated at home for 5 days, presented to the emergency department again on the fifth day with complaints of respiratory distress, fever, bruising with cough, and loss of peripheral pulse in the left lower extremity. Necessary tests were performed on the patient. An above-knee amputation was performed when a diagnosis of limb ischemic necrosis was made and no revascularization attempt was considered by the CVS department. This case study describes the coexistence of sudden lower extremity thrombosis and Covid-19 in our case without a known chronic disease.

Abstract
MolecuLight i:X is a noninvasive, portable device that captures images, measures wound areas, and allows the evaluation of the bacterial environment in real time. The aim of the study was to correlate the different fluorescence (light green, red, cyan) and dark red-purple-black color areas with average pH values in these areas and with average wound bed score (WBS). During a 4-week period, we enrolled 43 adult patients (23 females and 20 males) with clinically infected and uninfected chronic ulcers. In our study, the mean age was 68 years old. The etiologies were 21 venous ulcers, 3 arterial ulcers, 4 vasculitis, 7 pyoderma gangrenosum, 7 traumatic ulcers, and 1 neoplastic ulcer. The average area was 16.92 cm2 and the average WBS was 9.17. A total of 16 ulcers (37%) were positive for clinical signs and symptoms of infection and 27 ulcers were negative (63%). Thirty-six ulcers emitted a single fluorescence: cyan (n = 13), red (n = 1), light green (n = 14), and dark red-purple-black (n = 8). Six wounds showed a double fluorescence area: red and cyan (n = 1) and cyan and light green (n = 5). One ulcer emitted a triple fluorescence area: red, cyan, and light green. Overall in 43 ulcers, we found 43 fluorescence and 8 dark red-purple-black color. We found significant data between pH and fluorescence. pH values on wound bed confirm in a noninvasive way the correlation between fluorescence and bacterial burden. Moreover, MolecuLight i:X is able to detect objectively the bacterial proliferation, in contrast with pH which cannot distinguish different types of bacteria.

Abstract
Objective: High bacterial load contributes to chronicity of wounds and is diagnosed based on assessment of clinical signs and symptoms (CSS) of infection, but these characteristics are poor predictors of bacterial burden. Point-of-care fluorescence imaging (FL) MolecuLight i:X can improve identification of wounds with high bacterial burden (>104 colony-forming unit [CFU]/g). FL detects bacteria, whether planktonic or in biofilm, but does not distinguish between the two. In this study, diagnostic accuracy of FL was compared to CSS during routine wound assessment. Postassessment, clinicians were surveyed to assess impact of FL on treatment plan. Approach: A prospective multicenter controlled study was conducted by 20 study clinicians from 14 outpatient advanced wound care centers across the United States. Wounds underwent assessment for CSS followed by FL. Biopsies were collected to confirm total bacterial load. Three hundred fifty patients completed the study (138 diabetic foot ulcers, 106 venous leg ulcers, 60 surgical sites, 22 pressure ulcers, and 24 others). Results: Around 287/350 wounds (82%) had bacterial loads >104 CFU/g, and CSS missed detection of 85% of these wounds. FL significantly increased detection of bacteria (>104 CFU/g) by fourfold, and this was consistent across wound types (p < 0.001). Specificity of CSS+FL remained comparably high to CSS (p = 1.0). FL information modified treatment plans (69% of wounds), influenced wound bed preparation (85%), and improved overall patient care (90%) as reported by study clinicians. Innovation: This novel noncontact, handheld FL device provides immediate, objective information on presence, location, and load of bacteria at point of care. Conclusion: Use of FL facilitates adherence to clinical guidelines recommending prompt detection and removal of bacterial burden to reduce wound infection and facilitate healing.

Abstract
Hand injury is a common presentation in the emergency department (ED). The accurate assessment of hand injuries is essential to ensure optimal management, which may need to include referral to a tertiary trauma centre. However, hand injury assessment can be challenging, particularly in children. A better understanding of the accuracy of hand injury referrals to tertiary care can help improve clinical practice and clinician training. This article reports on a service improvement project that aimed to determine the accuracy of hand injury referrals from EDs and general practices to a tertiary trauma centre. The retrospective investigation found the accuracy of referrals to be high, but also identified areas where hand injury assessment required improvement, one of them being the training of clinicians referring complex cases to tertiary care.

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

Abstract
Wounds have become a significant public health challenge and consume a large amount of healthcare resources. Wounds can have severe negative effects on patients' quality of life, causing psychological and social distress, and may lead to significant periods of lost employment, resulting in financial loss. For nurses to manage wounds effectively, they need to be competent in undertaking holistic wound assessments. This article supports nurses' understanding by providing information on various types of wounds and their differing aetiologies. It also outlines the elements of a wound assessment and discusses some of the challenges that may be encountered during this process.

Abstract
Patients with diabetic neuropathy and peripheral arterial disease often suffer pain, develop foot wounds, and go on to lose limbs leaving them with a painful limb. Electrical stimulation is one possibility open to physicians. In this study, the effects of the FlowAid FA100 SCCD, a sequential contraction compression device, were tested. The FA100 device is noninvasive; it uses 4 electrodes to sequentially stimulate the calf muscles in a modified intermittent pneumatic compression manner. A total of 14 patients with diabetic neuropathy, peripheral arterial disease, unilateral amputation, and a painful limb were treated with FlowAid FA100 (FlowAid Medical Technologies Corporation, New York, NY) with prior ethical approval. The study design was open, pre-post intervention comparison, and nonrandomized. Pain perceived was measured using Visual Analogue Scale (VAS) scores. Assessments of ankle brachial index (ABI), ultrasound color Duplex, and tissue oxygen using the transcutaneous oxygen technique were done at baseline and 2 successive follow-ups 4 weeks apart. Three out of 14 patients dropped out on account of distances involved in traveling to the clinic. Eleven out of 14 patients experienced statistically significant reduction in pain mean VAS scores (7.5 ± 0.93 to 5.8 ± 1.47, P = .002) associated with increase in ABI (0.64 ± 0.06 to 0.69 ± 0.04, P < .001) and transcutaneous oxygen tension measured on the dorsum (29.4 ± 4.03 to 33.2 ± 5.26 in mm Hg, P = .005). When pain scores were regressed against ABI and transcutaneous oxygen tension values, there was a significant association between these (r = 0.8, P = .002). The reduction in pain following regular use of FlowAid was accompanied by beneficial and statistically significant increases in perfusion and oxygenation.

Abstract
OBJECTIVE Diagnostics which provide objective information to facilitate evidence-based treatment decisions could improve the chance of wound healing. Accurate wound measurements, objective bacterial assessment, and the regular, consistent tracking of these parameters are important aspects of wound care. This study aimed to assess the accuracy, clinical incorporation and documentation capabilities of a handheld bacterial fluorescence imaging device (MolecuLight i:X). METHOD Benchtop wound models with known dimensions and clinical wound images were repeatedly measured by trained clinicians to quantify accuracy and intra/inter-user coefficients of variation (COV) of the imaging device measurement software. In a clinical trial of 50 wounds, wound dimensions were digitally measured and fluorescence images were acquired to assess for the presence of bacteria at moderate-to-heavy loads. Finally, fluorescence imaging was implemented into the routine assessment of 22 routine diabetic foot ulcers (DFU) to determine appropriate debridement level and location based on bacterial fluorescence signals. RESULTS Wound measurement accuracy was >95% (COV <3%). In the clinical trial of 50 wounds, 72% of study wounds demonstrated positive bacterial fluorescence signals. Levine sampling of wounds was found to under-report bacterial loads relative to fluorescence-guided curettage samples. Furthermore, fluorescence documentation of bacterial presence and location(s) resulted in more aggressive, fluorescence-targeted debridement in 17/20 DFUs after standard of care debridement failed to eliminate bacterial fluorescence in 100% of DFU debridements. CONCLUSION The bacterial fluorescence imaging device can be readily implemented for objective, evidenced-based wound assessment and documentation at the bedside. Bedside localisation of regions with moderate-to-heavy bacterial loads facilitated improved sampling, debridement targeting and improved wound bed preparation.

Abstract
OBJECTIVE Telemedicine is an essential support system for clinical settings outside the hospital. Recently, the importance of the model for assessment of telemedicine (MAST) has been emphasised. The development of an eHealth-supported wound assessment system using artificial intelligence is awaited. This study explored whether or not wound segmentation of a diabetic foot ulcer (DFU) and a venous leg ulcer (VLU) by a convolutional neural network (CNN) was possible after being educated using sacral pressure ulcer (PU) data sets, and which CNN architecture was superior at segmentation. METHODS CNNs with different algorithms and architectures were prepared. The four architectures were SegNet, LinkNet, U-Net and U-Net with the VGG16 Encoder Pre-Trained on ImageNet (Unet_VGG16). Each CNN learned the supervised data of sacral pressure ulcers (PUs). RESULTS Among the four architectures, the best results were obtained with U-Net. U-Net demonstrated the second-highest accuracy in terms of the area under the curve (0.997) and a high specificity (0.943) and sensitivity (0.993), with the highest values obtained with Unet_VGG16. U-Net was also considered to be the most practical architecture and superior to the others in that the segmentation speed was faster than that of Unet_VGG16. CONCLUSION The U-Net CNN constructed using appropriately supervised data was capable of segmentation with high accuracy. These findings suggest that eHealth wound assessment using CNNs will be of practical use in the future.

Abstract
OBJECTIVE Clinical evaluation of signs and symptoms (CSS) of infection is imperative to the diagnostic process. However, patients with heavily colonised and infected wounds are often asymptomatic, leading to poor diagnostic accuracy. Point-of-care fluorescence imaging rapidly provides information on the presence and location of bacteria. This clinical trial (#NCT03540004) aimed to evaluate diagnostic accuracy when bacterial fluorescence imaging was used in combination with CSS for identifying wounds with moderate-to-heavy bacterial loads. METHODS Wounds were assessed by study clinicians using NERDS and STONEES CSS criteria to determine the presence or absence of moderate-to-heavy bacterial loads, after which the clinician prescribed and reported a detailed treatment plan. Only then were fluorescence images of the wound acquired, bacterial fluorescence determined to be present or absent and treatment plan adjusted if necessary. RESULTS We examined 17 VLUs/2 DFUs. Compared with CSS alone, use of bacterial fluorescence imaging in combination with CSS significantly improved sensitivity (22% versus 72%) and accuracy (26% versus 74%) for identifying wounds with moderate-to-heavy bacterial loads (≥104 CFU/g, p=0.002). Clinicians reported added value of fluorescence images in >90% of study wounds, including identification of wounds incorrectly diagnosed by CSS (47% of study wounds) and treatment plan modifications guided by fluorescence (73% of study wounds). Modifications included image-guided cleaning, treatment selection, debridement and antimicrobial stewardship. CONCLUSION Findings from this pilot study suggest that when used in combination with CSS, bacterial fluorescence may: (1) improve the diagnostic accuracy of identifying patients with wounds containing moderate-to-heavy bacterial loads and (2) guide more timely and appropriate treatment decisions at the point-of-care.

Abstract
While medical technology is continuing to improve healthcare outcomes and quality of life for patients, the number of people affected by medical device-related skin damage is increasing. In many cases, life-preserving medical devices used in interventions such as nasal continuous positive airway pressure or oxygen therapy can cause significant skin damage, with negative consequences including pain, infection and delayed hospital discharge. This article outlines methods that nurses can use to minimise the risk of skin damage, focusing primarily on the prevention of pressure ulcers. It also examines how nurses can work collaboratively with patients, manufacturers and regulatory bodies to reduce the risk of medical device-related skin damage in the future.

Abstract
Wounds have traditionally been classified as acute or chronic. While this classification is useful when attempting to estimate healing times, it might lead to an acceptance that some wounds will take longer to heal or might not heal at all. Chronic wounds can adversely affect patients' quality of life, and the management of these wounds may involve significant healthcare resources and costs. Chronic wounds rarely develop in healthy individuals and are often associated with pre-existing conditions that complicate wound healing, such as diabetes mellitus and vascular disease. This article discusses how acute wounds and chronic wounds are differentiated. It details the phases of wound healing and identifies potential barriers to progression through these phases. Enhancing nurses' understanding of chronic wounds will enable them to identify any potential barriers to wound healing early and remove or ameliorate them. While a holistic assessment should also include a thorough assessment of the wound itself, this is beyond the scope of this article.

Abstract
The persistent presence of pathogenic bacteria is one of the main obstacles to wound healing. Detection of wound bacteria relies on sampling methods, which delay confirmation by several days. However, a novel handheld fluorescence imaging device has recently enabled real-time detection of bacteria in wounds based on their intrinsic fluorescence characteristics, which differ from those of background tissues. This device illuminates the wound with violet (405 nm) light, causing tissues and bacteria to produce endogenous, characteristic fluorescence signals that are filtered and displayed on the device screen in real-time. The resulting images allow for rapid assessment and documentation of the presence, location, and extent of fluorescent bacteria at moderate-to-heavy loads. This information has been shown to assist in wound assessment and guide patient-specific treatment plans. However, proper image interpretation is essential to assessing this information. To properly identify regions of bacterial fluorescence, users must understand: (1) Fluorescence signals from tissues (e.g., wound tissues, tendon, bone) and fluids (e.g., blood, pus); (2) fluorescence signals from bacteria (red or cyan); (3) the rationale for varying hues of both tissue and bacterial fluorescence; (4) image artifacts that can occur; and (5) some potentially confounding signals from non-biological materials (e.g., fluorescent cleansing solutions). Therefore, this tutorial provides clinicians with a rationale for identifying common wound fluorescence characteristics. Clinical examples are intended to help clinicians with image interpretation-with a focus on image artifacts and potential confounders of image interpretation-and suggestions of how to overcome such challenges when imaging wounds in clinical practice.

Abstract
The heel is a common site for pressure ulcer development, particularly in people who are supine or semi-recumbent because of immobility. There is little protective subcutaneous tissue and no muscle or fascia within the heel, which means that it is vulnerable to pressure, friction and shear forces. Heel pressure ulceration remains a clinical challenge for nurses and the wider healthcare team, as well as a cause of pain and physical debilitation for the patient. This article examines the risk factors for heel pressure ulceration, and details patient assessment and specific measures that can be undertaken to prevent the development of heel pressure ulcers.

Abstract
Fingertip injuries in children are a common presentation in emergency settings. These injuries result from a variety of mechanisms with most occurring at home by crushing fingers in a door and are distressing for the child and parent or carer. It is essential that emergency clinicians respond competently and confidently. This article reviews the literature on the management of fingertip crush injuries to establish, where possible, best evidence. The article also describes the anatomy and assessment of the finger in relation to fractures of the distal phalanx, nail bed injury and subungual haematoma, and considers the use of antibiotics in the treatment of a subungual haematoma with a distal phalanx fracture.

Abstract
The aim of this study was to examine if using orthogonal and oblique factor analysis detect changes in health-related quality of life differently in diabetic patients on the Short Form-36 (SF-36) survey. A total of 155 patients had diabetic foot complications (DFC), and 145 patients had no DFCs. The SF-36 Physical Component Summary (PCS) and Mental Component Summary (MCS) scores were calculated using scoring coefficients determined by orthogonal and oblique rotation principle component analyses of the subscales. The DFC group had lower orthogonal ( P < .00001) and oblique PCS scores ( P < .00001). However, despite lower Mental Health subscale scores in the patients with DFCs, orthogonal MCS scores ( P = .156) did not differ. In contrast, the oblique MCS scores reflected the difference in the Mental Health subscale ( P = .0005). Orthogonal and oblique PCS scores did not differ significantly. However, orthogonal MCS scores were significantly higher than oblique MCS scores in those with DFCs ( P = .0004) and without DFCs ( P = .005). The shorter, 12-item SF-12 survey demonstrated similar results. Poorer physical function leads to higher orthogonal MCS scores than if determined by oblique scoring coefficients since Physical Function, Bodily Pain, and General Health are weighted more negatively in orthogonal coefficients when calculating the MCS score. Oblique scoring coefficients may address this issue, but further study is necessary to confirm whether oblique MCS scores accurately represent the mental health of patients with diabetic foot disease.

Abstract
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.

Abstract
The development of wound management protocols and guidelines such as the T.I.M.E. acronym are useful tools to aid wound care practitioners deliver effective wound care. The tissue, infection/inflammation, moisture balance and edge of wound (T.I.M.E.) framework provides a systematic approach for the assessment and management of the majority of acute and chronic wounds. The debridement of devitalised tissue from the wound bed, the reduction in wound bioburden and effective management of wound exudate - i.e., wound bed preparation - are barriers to wound healing progression that are targeted by T.I.M.E. There are a large number of wound dressings available to experienced wound care practitioners to aid in their goal of healing wounds. Despite the systematic approach of T.I.M.E., the large number of wound dressings available can introduce a level of confusion when dressing choices need to be made. Any simplification in dressing choice, for example by choosing a dressing system comprising of a limited number of dressings that are able to address all aspects of T.I.M.E., would be a valuable resource for delivering effective wound care. This article briefly reviews the principles of T.I.M.E. and describes the evidence for the use of a two-dressing, moisture balance-oriented, dressing-based wound management system.

Abstract
The D+Wound Solution is a mobile phone application (app) that assists users in the assessment and treatment of the wound. The app has 6 components for assessment: need for debridement, infection control, revascularization, and exudate control; whether it is chronic; and finally, the top surface of the skin. These components are named D.I.R.E.C.T. The app makes you review these components as an algorithm to provide a reasonable solution for dressing. It is designed to understand the status of the wound and provide a practical treatment idea for wound care providers. A total of 118 nurses were divided into 2 groups, designated as experienced and less-experienced groups, and surveyed. Both groups found the app to be helpful in making a treatment plan. However, the less-experienced group found it to be significantly more useful in assessing the wound ( P = .026) but difficult to understand the logic. The experienced group found the logic to be significantly easier to understand ( P = .018) and had significantly higher similarities ( P = .015) in treatment protocols compared with the less-experienced group. We may conclude that this app has a logical algorithm resembling experienced wound caregivers and is more useful in the less-experienced group.

Abstract
OBJECTIVE Accurate evaluation of non-healing, chronic wounds followed by the selection of an appropriate therapeutic strategy is a must for the foundation of health-care management. Assessment of non-healing chronic wounds in clinical practice in the Czech Republic is not standardised in acute care settings or in residential social care facilities. The aim of the study was to analyse the methods being used to assess non-healing, chronic wounds in residential social services in the Czech Republic, where more patients with chronic wounds are present because of the increasing incidence of wounds in old age. METHOD The research was carried out at 66 residential social care institutions across all regions of the Czech Republic. A mixed model was used for the research (participatory observation including creation of field notes and content analysis of documents for documentation and analysis of qualitative and quantitative data). The same methodology was used in previous work which has been done in acute care settings in 2013. RESULTS The results of this research have corroborated the inconsistencies in procedures used by general nurses for assessment of non-healing, chronic wounds. However, the situation was found to be more positive with regard to the evaluation of basic/fundamental parameters of a wound (e.g. size, depth and location of the wound) compared with the evaluation of more specific parameters (e.g. exudate or signs of infection). This included not only the number of observed variables, but also the action taken. Both were improved when a consultant for wound healing was present. CONCLUSION An effective strategy for wound management depends on the method and scope of the assessment of non-healing, chronic wounds in place in clinical practice in observed facilities; improvement may be expected following the general introduction of 'non-healing, chronic wound assessment' algorithm.

Abstract
AIM To determine whether bacteriological analysis of a wound swab is supportive in the clinical assessment of infection of a chronic wound. METHODS Patients attending an outpatient wound clinic who had endured a chronic wound for more than 3 weeks were clinically assessed for infection. In addition, standardized wound swabs were taken according to the Levine technique and the microbiological findings of the swabs compared with the clinical assessment of the wounds. RESULTS There was no significant relationship between the clinical assessments of the chronic wounds and the qualitative or quantitative bacteriological results of the swabs. CONCLUSION Microbiological analysis of wound swabs taken from chronic wounds to support clinical assessment of the wounds is waste of time and money. It may be preferable to assess chronic wounds clinically, however, validation studies of these signs and symptoms are needed.

Abstract
OBJECTIVE To verify the reliability and validity of FLIR ONE, a device connected to a smartphone, for the assessment of inflammation based on relative temperature increase compared with the thermography routinely used in pressure ulcer (PU) and diabetic foot assessment. METHOD Participants in this pilot cross-sectional observational study were recruited from the patients in the PU team rounds and the diabetic foot outpatient clinic at the university hospital in January 2015. Cohen's kappa coefficient with its 95% confidence intervals was used to evaluate the criterion-related validity and inter- and intra-rater reliability for the thermal imaging assessment. For assessing criterion-related validity, a hand-held high-end infrared thermography device was used to provide reference data. Comparison of thermal images between the smartphone-connected device and the hand-held device was performed with both a 'predetermined range' and an 'automatically-set range.' For assessing inter-rater reliability, two assessors evaluated the thermal images taken by the mobile thermography. For assessing intra-rater reliability, one assessor evaluated the thermal images twice. The thermal images were shown to the assessors at random. RESULTS Among 16 thermal images obtained from eight patients, kappa coefficients for each value were as follows: for the predetermined range and automatically-set range, respectively, the criterion-related validity was 1.00 (95% confidence interval 1.00-1.00) and 1.00 (95% confidence interval 1.00-1.00); the inter-rater reliability was 1.00 (95% confidence interval 1.00-1.00) and 1.00 (95% confidence interval 1.00-1.00); and the intra-rater reliability was 1.00 (95% confidence interval 1.00-1.00) and 1.00 (95% confidence interval 1.00-1.00). CONCLUSION This pilot study suggests that FLIR ONE can work as an alternative device for assessing subclinical inflammation in PUs and the diabetic foot in clinical settings. Our results may facilitate clinicians in accepting the routine use of thermal imaging assessment at the patients' bedside.
