Direct metagenomics investigation of non-surgical hard-to-heal wounds: a review.

BACKGROUND: Non-surgical chronic wounds, including diabetes-related foot diseases (DRFD), pressure injuries (PIs) and venous leg ulcers (VLU), are common hard-to-heal wounds. Wound evolution partly depends on microbial colonisation or infection, which is often confused by clinicians, thereby hampering proper management. Current routine microbiology investigation of these wounds is based on in vitro culture, focusing only on a limited panel of the most frequently isolated bacteria, leaving a large part of the wound microbiome undocumented. METHODS: A literature search was conducted on original studies published through October 2022 reporting metagenomic next generation sequencing (mNGS) of chronic wound samples. Studies were eligible for inclusion if they applied 16 S rRNA metagenomics or shotgun metagenomics for microbiome analysis or diagnosis. Case reports, prospective, or retrospective studies were included. However, review articles, animal studies, in vitro model optimisation, benchmarking, treatment optimisation studies, and non-clinical studies were excluded. Articles were identified in PubMed, Google Scholar, Web of Science, Microsoft Academic, Crossref and Semantic Scholar databases. RESULTS: Of the 3,202 articles found in the initial search, 2,336 articles were removed after deduplication and 834 articles following title and abstract screening. A further 14 were removed after full text reading, with 18 articles finally included. Data were provided for 3,628 patients, including 1,535 DRFDs, 956 VLUs, and 791 PIs, with 164 microbial genera and 116 species identified using mNGS approaches. A high microbial diversity was observed depending on the geographical location and wound evolution. Clinically infected wounds were the most diverse, possibly due to a widespread colonisation by pathogenic bacteria from body and environmental microbiota. mNGS data identified the presence of virus (EBV) and fungi (Candida and Aspergillus species), as well as Staphylococcus and Pseudomonas bacteriophages. CONCLUSION: This study highlighted the benefit of mNGS for time-effective pathogen genome detection. Despite the majority of the included studies investigating only 16 S rDNA, ignoring a part of viral, fungal and parasite colonisation, mNGS detected a large number of bacteria through the included studies. Such technology could be implemented in routine microbiology for hard-to-heal wound microbiota investigation and post-treatment wound colonisation surveillance.

Pressure injury education for older adults and carers living in community settings: A scoping review.

Older adults are at increased risk of pressure injuries (PIs) due to age-related changes. Traditionally, PI knowledge and education have been delivered in hospitals and residential aged care facilities, however, there remains a critical gap in understanding how PI knowledge on prevention and management is shared with older adults and their carers living in the community. We aimed to describe the nature and characteristics of structured and unstructured PI education programs available to community-dwelling older adults and their carers. As coping review was undertaken. We searched five databases: CINAHL, Medline, Scopus, Cochrane Library and ProQuest from 2009 to August 2023. The review was guided by Arksey and O'Malley's six-step framework and adhered to the PRISMA-ScR guidelines. It included primary peer-reviewed papers published in English, which focus on PI education for older adults and/or their carers living in community settings. Data extraction was organised in a table, and findings presented as a narrative summary. One-hundred and thirty-six papers were screened and four included in the review. Results indicate that consideration was placed on literacy levels and cognitive status of older adults and their carers when designing PI education materials. Educational materials such as leaflets/brochures, in-person training sessions or a combination of both were used. However, duration of these interventions varied, lasting for 1-4 weeks while others were completed over 12 months. Some improvements in PI knowledge such as how to treat PI, dietary requirements and importance of mobility were noted. However, information retention and its translation into effective long-term behaviour change remained unclear. In conclusion, adopting a multifaceted educational approach increases the effectiveness of PI knowledge translation. Continuous education, support and reinforcement on PIs over time are necessary when interacting with older adults and caregivers to ensure long-term management and prevention success. Conversations on PIs should start at the primary care levels when older adults and carers are visiting their GP clinics and accessing support services for other healthcare needs. Understanding older adults' and carers' literacy levels, cognitive status and cultural background can assist clinicians in designing and delivering fit-for-purpose PI educational interventions that are accessible, relatable and effective in promoting knowledge transfer and behaviour change. Carers are vital conduits in the care continuum. These factors will lead to a more informed, collaborative and person-centred approaches to PI management and prevention.

Treating chronic wounds in an acute care setting: the forgotten diagnosis.

BACKGROUND: Chronic wounds include lower extremity ulcers, diabetic foot ulcers, and pressure injuries, and can take months or years to heal. Wounds place a high burden on outpatient and inpatient care settings. This burden is expected to increase markedly in the United States as the population ages and with increased rates of diabetes, obesity, and COVID-19. PURPOSE: To articulate the effect of chronic, hard-to-heal wounds on acute care facilities, and how a few days of inpatient care can have a significant effect on the healing trajectory. METHODS: An expert panel of 7 members, all with extensive knowledge and experience in the assessment and treatment of chronic wounds in an acute care setting, was convened in March 2022. The panel discussed the role of hospitals as part of the longer-term healing pathway of chronic wounds. RESULTS: Chronic wounds have a significant effect on hospitals that includes unseen costs, bed occupancy, demands on bedside nurses, and wound complications that lead to extended stays or readmissions. A successful inpatient wound program offers appropriate identification of previously undiagnosed wounds, elevation of bedside care through simplified protocols, quickly and easily understood education and easy dressing selection, and comprehensive discharge planning with a multidisciplinary team for continuity of care and reduced risk of readmission. CONCLUSION: Hospitals can play a key role in the management of chronic wounds, thus reducing the effect on each facility and the wider care network.

Transiliac-Shortening Osteotomy to Treat Ischial Pressure Injury due to Fixed Pelvic Obliquity: A Case Report.

CASE: A 17-year-old adolescent boy with Gross Motor Function Classification System 5 cerebral palsy and neuromuscular scoliosis underwent posterior spinal fusion and segmental spinal instrumentation from T3 to the pelvis. He developed a right ischial pressure injury a few months postoperatively, which persisted despite nonoperative measures. He subsequently underwent an ipsilateral transiliac-shortening osteotomy 16 months after spinal surgery to treat his residual pelvic obliquity and the ischial pressure injury, which healed completely. At the 1-year follow-up visit, there were no further signs of pressure injury. CONCLUSION: This case report describes transiliac-shortening osteotomy as a viable treatment option for non-healing ischial pressure injuries secondary to fixed pelvic obliquity.

Pressure injury treatment by intermittent electrical stimulation (PROTECT-2): protocol for a multicenter randomized clinical trial.

BACKGROUND: Pressure ulcers account for a substantial fraction of hospital-acquired pathology, with consequent morbidity and economic cost. Treatments are largely focused on preventing further injury, whereas interventions that facilitate healing remain limited. Intermittent electrical stimulation (IES) increases local blood flow and redistributes pressure from muscle-bone interfaces, thus potentially reducing ulcer progression and facilitating healing. METHODS: The Pressure Injury Treatment by Intermittent Electrical Stimulation (PROTECT-2) trial will be a parallel-arm multicenter randomized trial to test the hypothesis that IES combined with routine care reduces sacral and ischial pressure injury over time compared to routine care alone. We plan to enroll 548 patients across various centers. Hospitalized patients with stage 1 or stage 2 sacral or ischial pressure injuries will be randomized to IES and routine care or routine care alone. Wound stage will be followed until death, discharge, or the development of an exclusion criteria for up to 3 months. The primary endpoint will be pressure injury score measured over time. DISCUSSION: Sacral and ischial pressure injuries present a burden to hospitalized patients with both clinical and economic consequences. The PROTECT-2 trial will evaluate whether IES is an effective intervention and thus reduces progression of stage 1 and stage 2 sacral and ischial pressure injuries. TRIAL REGISTRATION: ClinicalTrials.gov NCT05085288 Registered October 20, 2021.

Is Shock Wave Application Effective on Various Chronic Wounds in the Geriatric Population? Preliminary Clinical Study.

Purpose: Extracorporeal shock wave therapy (ESWT) is a beneficial adjunct modality for chronic wounds. Limited research has been conducted on pressure ulcers (PUs), while the majority of studies have focused on diabetic foot ulcers (DFUs) and venous leg ulcers (VLUs). This study aimed to evaluate the short-term effects of radial ESWT in older adults with chronic wounds. Patients and Methods: This study involved a total of 31 wounds: PUs (n=22), VLUs (n=7), and DFUs (n=2). A single radial ESWT was performed with 300 + 100 shocks per cm2, pressure of 2.5 bar, energy of 0.15 mJ/mm2, and frequency of 5 Hz. Assessments using digital planimetry and clinical methods, utilizing the Wound Bed Score (WBS) and the Bates-Jansen Wound Assessment Tool (BWAT) were performed before the radial ESWT application (M0) and one week after (M1). Results: A significant wound decrease in planimetry was noted (pre-ESWT vs post-ESWT), with wound area from 9.4 cm2 to 6.2 cm2, length from 6.4 cm to 3.9 cm, and width from 2.8 cm to 2.1 cm (p<0.001). Additionally, a substantial clinical improvement was noted in both the WBS with a 31.25% increase and the BWAT with a 20.00% increase (p<0.001). It was also found a significant correlation between the planimetric and clinical outcomes for both tools: WBS (r=-0.446, p=0.012) and BWAT (r=0.327, p=0.073). Conclusion: The ESWT application yields substantial immediate clinical effects that support the healing of chronic wounds in older adults. Even a single ESWT session can prove to be clinically effective and beneficial in the management of chronic wounds.

Changes in Interprofessional Practice During the COVID-19 Pandemic and the Effect on Patient Outcomes: A Retrospective Observational Study.

BACKGROUND: Changes in healthcare delivery were required during the first year of the COVID-19 pandemic. OBJECTIVE: The purpose of this study was to determine the impact of the approach to care of the COVID-19 patient on nursing sensitive indicators and nutrition therapy and the utilization of rehabilitation services during the first year of the pandemic in the acute care setting. METHOD: A retrospective study of 894 patients admitted with a COVID-19 diagnosis was conducted between March 2020 and February 2021 in 3-month cohorts. All charts were reviewed for general demographics and hospital data, nursing quality indicators, and nutritional and rehabilitation services for the first 30 days of admission. RESULTS: Differences in patient characteristics were noted among the cohorts. Variations were observed between time points in hospital-acquired pressure injury occurrence, with mechanical ventilation and proning being independent predictors of hospital-acquired pressure injuries. There were differences noted in the percentage of patients with a central line-associated bloodstream infection among the time points (P < .001), but there were no differences noted in catheter-associated urinary tract infections (P = .20). Overall, 15.5% had a malnutrition diagnosis, with most patients receiving 50% of prescribed calorie and protein needs. Rehabilitation services increased over time with these services being initiated earlier in the later cohorts (P < .001). DISCUSSION: The results of this study demonstrated the impact of the pandemic on outcomes in the areas of nursing, nutrition, and rehabilitation, which varied across quarterly cohorts as we learned and developed new practices and adapted to a novel pandemic.

Skin Tears Preventable With a Gentle Approach: A Case Series.

Skin tears are a major problem for patients and the health care professionals who treat them. Although opinions on their prevalence differ, it is estimated that they are encountered more frequently than pressure sores but are overlooked. Recommendations based on strong evidence were presented for the prevention and treatment of skin tears as classified by the International Skin Tear Advisory Panel. This case series includes the clinical status of 3 patients who developed skin tears while receiving care in the hospital, and the corrective and preventive practices related to skin tears. This article will contribute to raising the awareness of health care professionals in predicting, preventing, evaluating, and treating skin tears.

Braden score can independently predict 90-day mortality in critically ill patients with dementia.

BACKGROUND: Dementia is a significant cause of death in the older population and is becoming an important public health issue as the population ages and the prevalence of dementia increases. The Braden score is one of the most commonly used clinical tools to assess the risk of skin pressure injury in patients, and some studies have reported that it may reflect the state of frailty of patients. The present study attempted to explore the association between Braden score and 90-day mortality, pressure injury, and aspiration pneumonia in older patients with dementia in the intensive care unit (ICU). METHODS: The study involved extracting crucial data from the Medical Information Market for Intensive Care IV (MIMIC-IV) database using Structured Query Language, with a license certificate obtained after completing the necessary training and examination available on the MIMIC-IV website. A retrospective analysis was performed on older patients with dementia, aged 65 or older, who were first admitted to the ICU. Ninth and tenth revision International Classification of Diseases codes were used to identify patients with dementia. The primary outcome was 90-day mortality. Cox proportional hazards models were used to determine the association between Braden score and death, and hazard ratios (HR) and 95% confidence intervals (CI) were calculated. Propensity score matching and E-value assessments were employed for sensitivity analysis. RESULTS: A total of 2892 patients with a median age of approximately 85 years (interquartile range 78.74-89.59) were included, of whom 1625 were female (56.2%). Patients had a median Braden score of 14 (interquartile range 12-15) at ICU admission. Braden score at ICU admission was inversely associated with 90-day mortality risk after adjustment for demographics, severity of illness, treatment and medications, delirium, and sepsis (adjusted HR: 0.92, 95% CI: 0.87-0.98, p = 0.006). Patients were divided into two groups with a cut-off value of 15: high-risk group and low-risk group. Compared to the low-risk group (Braden score >15), the risk of 90-day mortality was significantly increased in the high-risk group (Braden score ≤15) (adjusted HR: 1.52, 95% CI: 1.10-2.09, p = 0.011, E-value: 2.01), the risk of pressure injury (adjusted OR: 2.62, 95% CI: 2.02-3.43, E-value: 2.62) and aspiration pneumonia (adjusted OR: 2.55, 95% CI: 1.84-3.61, E-value: 2.57) was also significantly higher. CONCLUSIONS: The Braden score may be a quick and simple screening tool to identify the risk of adverse outcomes in critically ill older adults with dementia.

Pressure Injury Prevention in Adult Critically Ill Patients: A Best Practice Implementation Project.

Implementation science is the process of integrating an intervention into practice within an organization or health system and is a useful strategy to improve practice, affect patient outcomes, and promote practice sustainability. In this series, AJN and the journal JBI Evidence Implementation have partnered to deliver examples of how health care facilities from around the world have worked to solve common patient care problems. Through this partnership, we strive to create awareness and share knowledge and experiences by publishing summaries of studies that have appeared in JBI Evidence Implementation. These summaries are designed to provide nursing teams with an overview of the barriers faced and the strategies and resources needed to improve practice and drive change at the unit level. Our goal is to ensure that AJN readers have access to important evidence-based information designed to influence patient outcomes and nursing practice.-Carl A. Kirton, DNP, MBA, RN, ANP, FAAN.

Urinary Catheter-Related Meatal Pressure Injury Risk Factors in Male Critical Care Patients: A Prospective Repeated-Measures Study.

OBJECTIVE: Urinary catheter-related meatal pressure injury (UCR-MPI) is a preventable and serious complication of indwelling urinary catheter use. This prospective study aimed to determine the prevalence and risk factors of UCR-MPI in male critical care patients. METHODS: A total of 138 male patients 18 years and older using an indwelling urinary catheter were included in the study. Participants' perineal areas were assessed daily for the development of MPI. RESULTS: The UCR-MPI prevalence was 26.1% (n = 36/138). Most patients (61.1%) had a grade I UCR-MPI with intact skin and mucosa and nonblanchable erythema. Urinary catheter irrigation (P = .001), lower Braden Scale scores (P = .040), lower Glasgow Coma Scale score (P = .002), higher Itaki Fall Risk Scale score (P = .040), higher dependency level (P = .027), hypoalbuminemia (P = .002), and perineal edema (P = .001) were risk factors for UCR-MPI. CONCLUSIONS: The prevalence of UCR-MPI was high in this sample. Providers should take preventive measures to prevent UCR-MPI in patients with a penis including early and frequent risk assessment.

Plasma-Based Scaffold Containing Bone-Marrow Mononuclear Cells Promotes Wound Healing in a Mouse Model of Pressure Injury.

Pressure injuries, or pressure ulcers, are a common problem that may lead to infections and major complications, besides being a social and economic burden due to the costs of treatment and hospitalization. While surgery is sometimes necessary, this also has complications such as recurrence or wound dehiscence. Among the newer methods of pressure injury treatment, advanced therapies are an interesting option. This study examines the healing properties of bone marrow mononuclear cells (BM-MNCs) embedded in a plasma-based scaffold in a mouse model. Pressure ulcers were created on the backs of mice (2 per mouse) using magnets and assigned to a group of ulcers that were left untreated (Control, n = 15), treated with plasma scaffold (Plasma, n = 15), or treated with plasma scaffold containing BM-MNC (Plasma + BM-MNC, n = 15). Each group was examined at three time points (3, 7, and 14 days) after the onset of treatment. At each time point, animals were subjected to biometric assessment, bioluminescence imaging, and tomography. Once treatment had finished, skin biopsies were processed for histological and wound healing reverse transcription polymerase chain reaction (RT-PCR) array studies. While wound closure percentages were higher in the Plasma and Plasma + BM-MNC groups, differences were not significant, and thus descriptive data are provided. In all individuals, the presence of donor cells was revealed by immunohistochemistry on posttreatment onset Days 3, 7, and 14. In the Plasma + BM-MNC group, less inflammation was observed by positron emission tomography-computed tomography (PET/CT) imaging of the mice at 7 days, and a complete morphometabolic response was produced at 14 days, in accordance with histological results. A much more pronounced inflammatory process was observed in controls than in the other two groups, and this persisted until Day 14 after treatment onset. RT-PCR array gene expression patterns were also found to vary significantly, with the greatest difference noted between both treatments at 14 days when 11 genes were differentially expressed.

[Incidence of pressure injuries associated with oxygen therapy devices in the neonatal intensive care unit]. / Incidencia de lesiones por presión asociadas a dispositivos de oxigenoterapia en la unidad de cuidados intensivos neonatales.

OBJECTIVE: The administration of oxygen therapy (O2) in neonatal intensive care units (NICU) increases the risk of developing pressure injuries (PBI). The aims of the study were to describe the incidence of PBI associated with O2 devices in the NICU, to identify, analyze and relate risk factors and the application of their preventive measures. METHODS: A retrospective, observational and analytical study of hospitalized neonates who developed PPL secondary to O2 devices in the NICU of the Miguel Servet University Hospital of Zaragoza was carried out. Socio-demographical, clinical, type of cot, humidity, temperature, type of oxygen therapy, ventilation mode, device and presence of ulcer (number, degree, location), and preventive measures were recorded. The study was approved by the Research Ethics Committee of the Autonomous Community of Aragon. Statistical analysis was performed using Jamovi 2.3.13®. RESULTS: A total of 191 neonates were included, of whom 158 (82.7%) received O2. Of those who received oxygen therapy, 64.10% (25) were infants, mean total age 5.20±8.46 days and mean weight 1,460.03±777.57 grams. 24.68% presented with device-associated PPL, with a mean number of days of admission at the time of onset of 3.98±5.03 days. 94.74% (36) of the lesions were grade I and 84.62% (33) were located in the nasal septum. CONCLUSIONS: The incidence of pressure injuries associated with different oxygen therapy devices increases with decreasing gestational age. The risk increases with hospital stay, with the presence of medical devices, in particular non-invasive mechanical ventilation, being the main causal relationship.

OBJETIVO: La administración de oxigenoterapia en las unidades de cuidados intensivos neonatales (UCIN) supone un aumento del riesgo de desarrollar lesiones por presión (LPP).

METODOS: Se realizó un estudio retrospectivo, observacional y analítico de neonatos hospitalizados que desarrollaran una LPP secundaria a dispositivos de O2 en la UCIN del Hospital Universitario Miguel Servet de Zaragoza. Las variables registradas fueron las sociodemográficas, las clínicas, el tipo de cuna, la humedad, la temperatura, el tipo de oxigenoterapia, el tipo de ventilación, el dispositivo utilizado, la presencia de úlcera (número, grado, localización) y las medidas preventivas aplicadas. El estudio fue aprobado por el Comité de Ética de la Investigación de la Comunidad Autónoma de Aragón. El análisis estadístico se realizó mediante Jamovi 2.3.13®. RESULTADOS: Se incluyeron 191 neonatos, de los cuales 158 (82,7%) recibieron oxigenoterapia. El 64,10% de ellos fueron niños, la media de edad fue de 5,20±8,46 días y la de peso de 1.460,0±777,57 gramos. El 24,68% presentaron LPP asociada a dispositivo, con una media de días de ingreso en el momento de la aparición de 3,98±5,03 días. El 94,74% de las lesiones fueron de grado I y el 84,62% se localizaron en tabique nasal. CONCLUSIONES: La incidencia de LPP asociada a los diferentes dispositivos de oxigenoterapia aumenta a medida que disminuye la edad gestacional. El riesgo aumenta con la estancia hospitalaria, siendo la presencia de dispositivos médicos, en particular la ventilación mecánica no invasiva, la principal causa.

Impact of shear stress on sacral pressure injury from table rotation during laparoscopic colorectal surgery performed in the lithotomy position.

This study aimed to evaluate the impact of shear stress on surgery-related sacral pressure injury (PI) after laparoscopic colorectal surgery performed in the lithotomy position. We included 37 patients who underwent this procedure between November 2021 and October 2022. The primary outcome was average horizontal shear stress caused by the rotation of the operating table during the operation, and the secondary outcome was interface pressure over time. Sensors were used to measure shear stress and interface pressure in the sacral region. Patients were divided into two groups according to the presence or absence of PI. PI had an incidence of 32.4%, and the primary outcome, average horizontal shear stress, was significantly higher in the PI group than in the no-PI group. The interface pressure increased over time in both groups. At 120 min, the interface pressure was two times higher in the PI group than in the no-PI group (PI group, 221.5 mmHg; no-PI group, 86.0 mmHg; p < 0.01). This study suggested that shear stress resulting from rotation of the operating table in the sacral region by laparoscopic colorectal surgery performed in the lithotomy position is the cause of PI. These results should contribute to the prevention of PI.

A survey of skin failure perceptions amongst pressure injury management staff in China: A cross-sectional study.

This study sought to evaluate the perceptions of pressure injury (PI) management staff regarding skin failure (SF). Additionally, an analysis of influencing factors based on the collected data was conducted to establish a foundation for targeted SF training. A descriptive, cross-sectional survey was undertaken in October-November 2023, utilising a convenience sampling method involving selected management staff of PI from 16 provinces in China. A total of 501 nursing participants were included, exhibiting an overall perception level that was moderately low. Although the majority were aware of the possibility of SF (n = 417, 83.23%), only 60% reported an understanding of the fundamentals of SF, with the lowest level of comprehension observed in differentiating between SF and PI (n = 212, 42.31%). Overall attitudes were generally positive. Regarding behaviour, active learning was more prevalent (n = 340, 67.86%), but training is less (n = 287, 57.29%). Family education (n = 401, 80.04%) and nursing record monitoring (n = 426, 85.03%) demonstrated better behaviour. Further analysis revealed that training (t = 13.937, p < 0.001) and professional title (F = 4.681, p = 0.010) had a significant effect on participants' perceptions. These findings underscore that there remains a substantial lack of perception about SF amongst participants. Overall, participants exhibited a positive attitude towards SF, highlighting the need for future improvements in SF training.

Application of deep learning to pressure injury staging.

OBJECTIVE: Accurate assessment of pressure injuries (PIs) is necessary for a good outcome. Junior and non-specialist nurses have less experience with PIs and lack clinical practice, and so have difficulty staging them accurately. In this work, a deep learning-based system for PI staging and tissue classification is proposed to help improve its accuracy and efficiency in clinical practice, and save healthcare costs. METHOD: A total of 1610 cases of PI and their corresponding photographs were collected from clinical practice, and each sample was accurately staged and the tissues labelled by experts for training a Mask Region-based Convolutional Neural Network (Mask R-CNN, Facebook Artificial Intelligence Research, Meta, US) object detection and instance segmentation network. A recognition system was set up to automatically stage and classify the tissues of the remotely uploaded PI photographs. RESULTS: On a test set of 100 samples, the average precision of this model for stage recognition reached 0.603, which exceeded that of the medical personnel involved in the comparative evaluation, including an enterostomal therapist. CONCLUSION: In this study, the deep learning-based PI staging system achieved the evaluation performance of a nurse with professional training in wound care. This low-cost system could help overcome the difficulty of identifying PIs by junior and non-specialist nurses, and provide valuable auxiliary clinical information.

Improving outcomes for patients with hard-to-heal wounds following adoption of the Wound Hygiene Protocol: real-world evidence.

OBJECTIVE: To evaluate the impact of a four-step biofilm-based wound care strategy, Wound Hygiene Protocol (WHP: cleanse, debride, refashion, and dress), on hard-to-heal wounds. METHOD: This was a prospective, real-world analysis of hard-to-heal wounds managed with the WHP that incorporated Aquacel Ag+ (Convatec Ltd., UK) dressings. Data were captured electronically between April 2021 and December 2022. The primary endpoint was change in wound volume from baseline to final assessment. RESULTS: A total of 693 wounds in 669 patients (median patient age: 74 years) were included in the analysis with a median treatment time of 31 days. Most health professionals were general nurses (50%) or nurse practitioners (38%). Patient homes (27%) and community clinics (27%) were the most common clinical settings. Venous leg ulcers (26%) and pressure ulcers/injuries (17%) were the most common wound type. Duration was >12 months in 21% of wounds. At baseline, the mean wound volume was 57.8cm3. At the final assessment, mean wound volume was 17.2cm3, corresponding to an 80% reduction from baseline; p<0.001). At baseline, 66% of wounds were static or deteriorating. At final assessment, this had decreased to 5%, and 94% had improved or healed. Exudate levels were moderate or high in 69% of wounds at baseline which decreased to 25% at final assessment (p<0.001). Suspected biofilm and local wound infection decreased from 79% and 43%, respectively, at baseline, to 18% and 3%, respectively, at final assessment (p<0.001 for both). CONCLUSION: The WHP is a new proposed standard of care that successfully treated hard-to-heal wounds by addressing the key local barriers to wound healing.
