Background Formation of new blood vessels, by either angiogenesis or vasculogenesis, is critical for normal wound healing. Major processes in neovascularization include (i) growth-promoting or survival factors, (ii) proteolytic enzymes, (iii) activators of multiple differentiated and progenitor cell types, and (iv) permissible microenvironments. A central aim of wound healing research is to “convert” chronic, disease-impaired wounds into those that will heal. The problem Reduced ability to re-establish a blood supply to the injury site can ultimately lead to wound chronicity. Basic/Clinical Science Advances (1) Human fetal endothelial progenitor cells can stimulate wound revascularization and repair following injury, as demonstrated in a novel mouse model of diabetic ischemic healing. (2) Advances in bioengineering reveal exciting alternatives by which wound repair may be facilitated via the creation of vascularized microfluidic networks within organ constructs created ex vivo for wound implantation. (3) A “personalized” approach to regenerative medicine may be enabled by the identification of protein components present within individual wound beds, both chronic and acute. Clinical Care Relevance Despite the development of numerous therapies, impaired angiogenesis and wound chronicity remain significant healthcare problems. As such, innovations in enhancing wound revascularization would lead to significant advances in wound healing therapeutics and patient care. Conclusion Insights into endothelial progenitor cell biology together with developments in the field of tissue engineering and molecular diagnostics should not only further advance our understanding of the molecular mechanisms regulating wound repair but also offer innovative solutions to promote the healing of chronic and acute wounds in vivo.

Publicly Reported Wound Healing Rates: The Fantasy and the Reality

Fife, Caroline E.; Eckert, Kristen A.; Carter, Marissa J.

2018-01-01

Significance: We compare real-world data from the U.S. Wound Registry (USWR) with randomized controlled trials and publicly reported wound outcomes and develop criteria for honest reporting of wound outcomes, a requirement of the new Quality Payment Program (QPP). Recent Advances: Because no method has existed by which wounds could be stratified according to their likelihood of healing among real-world patients, practitioners have reported fantastically high healing rates. The USWR has developed several risk-stratified wound healing quality measures for diabetic foot ulcers (DFUs) and venous leg ulcers (VLUs) as part of its Qualified Clinical Data Registry (QCDR). This allows practitioners to report DFU and VLU healing rates in comparison to the likelihood of whether the wound would have healed. Critical Issues: Under the new QPP, practitioners must report at least one practice-relevant outcome measure, and it must be risk adjusted so that clinicians caring for the sickest patients do not appear to have worse outcomes than their peers. The Wound Healing Index is a validated risk-stratification method that can predict whether a DFU or VLU will heal, leveling the playing field for outcome reporting and removing the need to artificially inflate healing rates. Wound care practitioners can report the USWR DFU and VLU risk-stratified outcome measure to satisfy the quality reporting requirements of the QPP. Future Directions: Per the requirements of the QPP, the USWR will begin publicly reporting of risk-stratified healing rates once quality measure data have met the reporting standards of the Centers for Medicare and Medicaid Services. Some basic rules for data censoring are proposed for public reporting of healing rates, and others are needed, which should be decided by consensus among the wound care community. PMID:29644145

Recent Advances in Fractional Laser Resurfacing: New Paradigm in Optimal Parameters and Post-Treatment Wound Care

PubMed Central

Hsiao, Francis C.; Bock, Gerald N.; Eisen, Daniel B.

2012-01-01

Background Laser plays an increasingly prominent role in skin rejuvenation. The advent of fractional photothermolysis revolutionizes its application. Microcolumns of skin are focally injured, leaving intervening normal skin to facilitate rapid wound healing and orderly tissue remodeling. The Problem Even with the popularity of fractional laser devices, we still have limited knowledge about the ideal treatment parameters and postlaser wound care. Basic/Clinical Science Advances Many clinicians believe that higher microbream energy in fractional laser devices results in better clinical outcome. Two recent studies argue against this assumption. One article demonstrates that lower fluence can induce comparable molecular changes with fewer side effects. Another study corroborates this by showing that lower-density settings produce similar clinical outcome in scar remodeling as higher-density ones, but with fewer side effects. To shed light on the optimal post-treatment wound care regimen from fractional ablative resurfacing, another paper shows that platelet-rich plasma (PRP) can reduce transepidermal water loss and skin color changes within 1 month after treatment. Clinical Care Relevance For fractional nonablative resurfacing, lower settings in fluence or density may produce similar dermal remodeling as higher settings and with a better side-effect profile. Moreover, autologous PRP appears to expedite wound healing after fractional ablative resurfacing. Conclusion Lower microbeam energy in fractional laser resurfacing produces similar molecular changes and clinical outcome with fewer side effects. The findings might portend a shift in the paradigm of treatment parameters. Autologous PRP can facilitate better wound healing, albeit modestly. Long-term follow-ups and larger studies are necessary to confirm these findings. PMID:24527307

The ever improving health standards in terms of quality and more efficient health care result in an increase in life expectancy, thus increasing the number of elderly people in the population. A higher level of activity in elderly population leads to greater incidence of injuries, and on the other hand, there is an increasing number of comorbidities. Circulatory disorders, diabetes mellitus, metabolic imbalances, etc. and a reduced biological potential of tissue regeneration result in an increased number of chronic wounds that pose a significant health, social and economic burden on the society. These conditions require significant involvement of medical and non-medical staff in pre-hospital institutions. Significant material and other health care resources are allocated for the treatment of chronic wounds. These conditions result in a lower quality of life of patients and their families and caregivers. Debridement is a crucial medical procedure for the treatment of acute and chronic wounds. The result of debridement is removal of all barriers within and around the wound that obstruct physiological processes of wound healing. Debridement is a repeating process when indicated. There are several types of debridement, each with its advantages and disadvantages. The method of debridement should be determined by the physician or other professional trained person on the basis of wound characteristics and in accordance with their expertise and capabilities. In the same wound, we can combine different types of debridement, all with the goal of faster and better wound healing.

The wound healing includes non-healing and overhealing of the wounds. The results of wound healing are well known by people such as non-healing of the diabetic ulcer or hypertrophic scar after deep burn. In this issue, three papers involve in wound healing, one about autologous adipose-derived mesenchymal stem cells injected into wound or scar of rabbit ear, one about severe hypoxia and hypoalbuminemia inducing human hypertrophic scar derived fibroblast apoptosis in vitro, and another about the dysfunction of protein kinase B/mammalian target of rapamycin signaling pathway contributing to the pathophysiological characteristics of diabetic skin and non-healing wound. The basic problem of hypertrophic scar study is lacking an ideal animal model. Although rabbit ear model or red Duroc pig model has been used widely for study on hypertrophic scar, they can not fully represent human dermal fibrosis after deep trauma on the skin. I recommend A novel nude mouse model of hypertrophic scarring using scratched full thickness human skin grafts recently published in Advances in Wound Care to the readers. The author emphasizes that the wound healing study is still in the situation like the game of " blind men and an elephant" .

Plastic Surgery Challenges in War Wounded II: Regenerative Medicine

PubMed Central

Valerio, Ian L.; Sabino, Jennifer M.; Dearth, Christopher L.

2016-01-01

Background: A large volume of service members have sustained complex injuries during Operations Iraqi Freedom (OIF) and Enduring Freedom (OEF). These injuries are complicated by contamination with particulate and foreign materials, have high rates of bacterial and/or fungal infections, are often composite-type defects with massive soft tissue wounds, and usually have multisystem involvement. While traditional treatment modalities remain a mainstay for optimal wound care, traditional reconstruction approaches alone may be inadequate to fully address the scope and magnitude of such massive complex wounds. As a result of these difficult clinical problems, the use of regenerative medicine therapies, such as autologous adipose tissue grafting, stem cell therapies, nerve allografts, and dermal regenerate templates/extracellular matrix scaffolds, is increased as adjuncts to traditional reconstructive measures. Basic and Clinical Science Advances: The beneficial applications of regenerative medicine therapies have been well characterized in both in vitro studies and in vivo animal studies. The use of these regenerative medicine techniques in the treatment of combat casualty injuries has been increasing throughout the recent war conflicts. Clinical Care Relevance: Military medicine has shown positive results when utilizing certain regenerative medicine modalities in treating complex war wounds. As a result, multi-institution clinical trials are underway to further evaluate these observations and reconstruction measures. Conclusion: Successful combat casualty wound care often requires a combination of traditional aspects of the reconstructive ladder/elevator with adoption of various regenerative medicine therapies. Due to the recent OIF/OEF conflicts, a high volume of combat casualties have benefited from adoption of regenerative medicine therapies and increased access to innovative clinical trials. Furthermore, many of these patients have had long-term follow-up to report on clinical outcomes that substantiate current treatment paradigms and concepts within regenerative medicine, reconstructive, and rehabilitation care. These results are applicable to not only combat casualty care but also to nonmilitary patients. PMID:27679752

The foundation of health care management of patients with non-healing, chronic wounds needs accurate evaluation followed by the selection of an appropriate therapeutic strategy. Assessment of non-healing, chronic wounds in clinical practice in the Czech Republic is not standardised. The aim of this study was to analyse the methods being used to assess non-healing, chronic wounds in inpatient facilities in the Czech Republic. The research was carried out at 77 inpatient medical facilities (8 university/faculty hospitals, 63 hospitals and 6 long- term hospitals) 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 results of this research have corroborated the suspicion of 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 evaluation of basic/fundamental parameters of a wound (e.g. size, depth and location of a 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 significantly improved when a consultant for wound healing was present (P = 0·047). The same applied to facilities possessing a certificate of quality issued by the Czech Wound Management Association (P = 0·010). In 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 a 'non-healing, chronic wound assessment' algorithm. © 2014 The Authors.

Situating wound management: technoscience, dressings and 'other' skins.

PubMed

Rudge, T

1999-09-01

This paper addresses the notion of wound care as a technology of skin and other skins imbued with the combined power of technology and science. It presents the discourses of wound care evident in the accounts of patients and nurses concerning this care, and discussions about wounds in wound care interest groups, journals, and advertising material about wound care products. The discussion focuses on wounds and wound dressings as effects immanent in the power relations of discourses of wound care. These effects colour and influence nurses' responses to wounds and wound care products. Moreover, the discourses that portray these practices are evidence of the complex articulation between technoscience and gender. Nurses and patients are fascinated by wound technoscience and lured towards it by its potential for mastery and control over wounds. Such seductions are evident in the texts of nurses, patients, and pharmaceutical advertisements for wound care products. Finally, the ways that these representations are used to talk about and market wound care products are shown as exemplifying the finer points of wound management as a nursing technoscience.

Pneumonia is one of the common complications of wounds of any localization. Therapists are involved into the treatment of lung lesions in wounded in the ICU, in the surgical and if the patient arrives "on follow-up care,"--in the medical ward. The article analyzes the main statistical indicators reflecting the prevalence and clinical and pathogenetic characteristics of lung pathology in wounded during the Great Patriotic War, during the fighting Soviet troops in the Republic of Afghanistan, the 1st and 2nd Chechen campaign. Pneumonia as a manifestation of traumatic disease can occur in two ways. Primary pneumonia is in close connection with the pathogenetic traumatic injury. Secondary lung lesions complicate the injury at a later date and are due to the introduction of a nosocomial infection process flora. We describe the clinical picture of pneumonia in the affected, the basic pathogenesis, principles of therapy. Successful treatment of lung pathology in wounded depends on the performance of a complex of activities involving a wide range of doctors of various specialties.

Off-Loading Practices for the Wounded Foot: Concepts and Choices

PubMed Central

Mrdjenovich, Donald E.

2011-01-01

A wound practitioner’s best-laid plan of care and strategy for healing an ulcerated foot is doomed to fail without a properly conceived approach based on sound off-loading principles. Wound healing that has stalled despite best-practice techniques may require reevaluation of off-loading choices. This is particularly true in the patient with abnormal foot pathologies. Special considerations are certainly required with neuropathic ulcers; however, any wound on a weight-bearing surface of the foot requires proper off-loading. This discussion explores the basic biomechanical and pathomechanical concepts that modify and influence ambulation and gait patterns. Integration of these concepts into the choices for off-loading to deter pathologic influences will alert the reader of precautionary measures and other factors for consideration. The aim of this column is to provide both an adequate working knowledge of the available off-loading devices and the necessary tools and concepts needed to stimulate wise decision protocols for wound management and healing.

Wound-healing outcomes applying standardized protocols have typically been measured within controlled clinical trials, not natural settings. Standardized protocols of wound care have been validated for clinical use, creating an opportunity to measure the resulting outcomes. Wound-healing outcomes were explored during clinical use of standardized validated protocols of care based on patient and wound assessments. This was a prospective multicenter study of wound-healing outcomes management in real-world clinical practice. Healing outcomes from March 26 to October 31, 2001, were recorded on patients in 3 long-term care facilities, 1 long-term acute care hospital, and 12 home care agencies for wounds selected by staff to receive care based on computer-generated validated wound care algorithms. After diagnosis, wound dimensions and status were assessed using a tool adapted from the Pressure Sore Status Toolfor use on all wounds. Wound, ostomy, and continence nursing professionals accessed consistent protocols of care, via telemedicine in home care or paper forms in long-term care. A physician entered assessments into a desktop computer in the wound clinic. Based on evidence that healing proceeds faster with fewer infections in environments without gauze, the protocols generally avoided gauze dressings. Most of the 767 wounds selected to receive the standardized-protocols of care were stage III-IV pressure ulcers (n = 373; mean healing time 62 days) or full-thickness venous ulcers (n = 124; mean healing time 57 days). Partial-thickness wounds healed faster than same-etiology full-thickness wounds. These results provide benchmarks for natural-setting healing outcomes and help to define and address wound care challenges. Outcomes primarily using nongauze protocols of care matched or surpassed best previously published results on similar wounds using gauze-based protocols of care, including protocols applying gauze impregnated with growth factors or other agents.

Because nurses frequently participate in decisions related to wound care, learning about wounds and their care during undergraduate education is critical. A cross-sectional, descriptive, quality improvement project was conducted in an introductory baccalaureate nursing course to identify: 1) the types of patients with wounds assigned to beginning students, 2) patient wound care procedures and dressings, and 3) student level of participation in wound care. Data were collected from the weekly notes recorded about students' (N = 49) patient care experiences in 3 acute care hospitals for 9 clinical days during 1 semester. Data were recorded on a paper-and-pencil form by instructors at the end of the clinical day and included type of wound, wound irrigation, dressing, technique of care, and student's participation. Descriptive statistics were used to examine the frequency and distribution of the wound characteristics and care assessed. Of the 284 patients assigned to students, 75 (26.4%) had a wound. The most common wound was a surgical incision (49, 65%) and was closed (36, 73.5%). Twenty-six (26) patients had a pressure ulcer, most commonly Stage II. The most common dressing was dry gauze (29). Damp gauze was used on 18 wounds. Wound irrigation was recorded for 24 wound protocols and performed with a bulb syringe or by pouring the solution from a container. Generally, nonsterile wound care was performed. Twenty-five (25) students performed wound care with the instructor, 16 watched the care performed by another clinician, and 10 participated with another nurse in the wound care. For 22 patients, the wound care was neither observed nor performed because either it was not time for the dressing to be changed or it was only to be changed by a medical team. From these data, it was concluded beginning nursing students had some, but limited, clinical experience with patients with wounds. Students' wound care experiences need further examination, especially across multiple educational courses.

Wound healing in orthopaedic care is affected by the causes of the wound, as well as concomitant therapies used to repair musculoskeletal structures. Promoting the health of the host and creating an environment to foster natural healing processes is essential for helping to restore skin integrity. Normal wound healing physiologic processes, factors affecting wound healing, wound classification systems, unique characteristics of orthopaedic wounds, wound contamination and drainage characteristics, and potential complications are important to understand in anticipation of patient needs. Accurate wound assessment and knowledge of nursing implications with specific wound care measures (cleansing, debridement, and dressings) is important for quality care. New technologies are enhancing traditional wound care measures with goals of effective comfortable wound care to promote restoration of skin integrity.

Since the caveman, man has been tending to his wounds. Wound care evolved from magical incantations, potions, and ointments, to a systematic text of wound care and surgery from Hippocrates and Celsus. These advances were lost after the fall of the Roman Empire. In Europe, the Middle Ages were a regression of wound care back to potions and charms. It was'nt until the time of large armies using muskets and cannons that surgical wound care emerged again. This article will briefly highlight major milestones in wound care.

Although the benefits of wound care services and multidisciplinary team care have been well elaborated on in the literature, there is a gap in the actual practice of wound care and the establishment of an efficient referral system. The conceptual framework for establishing efficient wound management services requires elucidation.A wound care center was established in a tertiary hospital in 2010, staffed by an integrated multidisciplinary team including plastic surgeons, a full-time coordinator, a physical therapist, occupational therapists, and other physician specialists. Referral patients were efficiently managed following a conceptual framework for wound care. This efficient wound management service consists of 3 steps: patient entry and onsite immediate wound debridement, wound re-evaluation, and individual wound bed preparation plan. Wound conditions were documented annually over 4 consecutive years.From January 2011 to December 2014, 1103 patients were recruited from outpatient clinics or inpatient consultations for the 3-step wound management service. Of these, 62% of patients achieved healing or improvement in wounds, 13% of patients experienced no change, and 25% of patients failed to follow-up. The outcome of wound treatment varied by wound type. Sixty-nine percent of diabetic foot ulcer patients were significantly healed or improved. In contrast, pressure ulcers were the most poorly healed wound type, with only 55% of patients achieving significantly healed or improved wounds.The 3-step wound management service in the wound care center efficiently provided onsite screening, timely debridement, and multidisciplinary team care. Patients could schedule appointments instead of waiting indefinitely for care. Further wound condition follow-up, education, and prevention were also continually provided.

This study was a component of a broader review to evaluate burn care in South Africa. A prospective audit of 353 children with thermal injuries admitted to the Red Cross War Memorial Children's Hospital in Cape Town was performed during 2012/2013. The audit was based to assess the adherence of initial burn management to the provincial policy guidelines on the clinical management of the burn wound. The community management of each patient prior to admission to a burns centre was assessed for the following: basic demographics, emergency home management, wound cover, analgesia and transport to medical facilities. Their ages ranged from 1 month to 14 years. The average total body surface area [TBSA] was 15% [1-86%]. Most of the injuries were due to hot water accidents [78.5%] followed by flame burns (9%), direct contact and electricity burns. Two hundred and twenty five children [63%] received first aid measures at home, including cooling with water [166] ice [30] and a cooling agent. No cooling was instituted in 130 and 65% of the patient's wounds were cooled for 10 min or less. Eighty percent proceeded to the referral centre or burns unit without their wounds being covered; with only 19 patients having any medical type of dressing available at home. Two hundred and ninety five children [83.6%] received pain medication prior to admission at the burns unit. Of the 316 patients not directly attending the burns unit, 137 received i.v. fluids of which 95 had burns greater than 10% TBSA. None of the patients were in shock on admission and all i.v. lines were functioning. Forty-four children with burns greater than 10% did not receive i.v. fluids. The audit identified six factors that were inadequately addressed during the pre-admission period: first aid, cooling of the wound, early covering of the wound, resuscitation, pain management and transfer. If these could be readdressed, basic burn care would be substantially improved in the study area. Copyright © 2015 Elsevier Ltd and ISBI. All rights reserved.

To provide information about palliative wound care management strategies for palliative patients and their circles of care. This continuing education activity is intended for physicians and nurses with an interest in skin and wound care. After participating in this educational activity, the participant should be better able to: 1. Recognize study findings, assessment tools, and non-pharmacologic strategies used for patients with palliative wounds. 2. Summarize pharmacologic and dressing treatment strategies used for wound care management of palliative patients. The principles of palliative wound care should be integrated along the continuum of wound care to address the whole person care needs of palliative patients and their circles of care, which includes members of the patient unit including family, significant others, caregivers, and other healthcare professionals that may be external to the current interprofessional team. Palliative patients often present with chronic debilitating diseases, advanced diseases associated with major organ failure (renal, hepatic, pulmonary, or cardiac), profound dementia, complex psychosocial issues, diminished self-care abilities, and challenging wound-related symptoms. This article introduces key concepts and strategies for palliative wound care that are essential for interprofessional team members to incorporate in clinical practice when caring for palliative patients with wounds and their circles of care.

As restoration of the integument is paramount to wound healing, dermatologists should be central to managing wounds; yet this is often not the case. If a training gap exists during residency training, this may account for the observed discrepancy. To identify United States (US) dermatology residents' impressions regarding their preparedness to care for wounds, and to assess the amount and type of training devoted to wound care during residency. An online survey among current US dermatology residents enrolled in a residency training program. The primary goal was to determine whether dermatology residents believe more wound care education is needed, evaluate preparedness to care for wounds, and identify future plans to manage wounds. Responses were received from 175 of 517 (33.8%) US Dermatology residents contacted. The majority of residents did not feel prepared to manage acute (78.3%) and chronic (84.6%) wounds. Over three quarters (77.1%) felt that more education is needed. Fewer than half (49.1% and 35.4%) of residents planned to care for acute and chronic wounds, respectively, when in practice. There is a gap in wound care education in US dermatology residency training. This translates to a low percentage of dermatology residents planning to care for wounds in future practice. Dermatology residents need to receive focused wound care training in order to translate the underpinnings of wound healing biology and ultimately better serve patients.

Significance: The increasing complexity of medical and surgical care provided to pediatric patients has resulted in a population at significant risk for complications such as pressure ulcers, nonhealing surgical wounds, and moisture-associated skin damage. Wound care practices for neonatal and pediatric patients, including the choice of specific dressings or other wound care products, are currently based on a combination of provider experience and preference and a small number of published clinical guidelines based on expert opinion; rigorous evidence-based clinical guidelines for wound management in these populations is lacking. Recent Advances: Advances in the understanding of the pathophysiology of wound healing have contributed to an ever-increasing number of specialized wound care products, most of which are predominantly marketed to adult patients and that have not been evaluated for safety and efficacy in the neonatal and pediatric populations. This review aims to discuss the available data on the use of both more traditional wound care products and newer wound care technologies in these populations, including medical-grade honey, nanocrystalline silver, and soft silicone-based adhesive technology. Critical Issues: Evidence-based wound care practices and demonstration of the safety, efficacy, and appropriate utilization of available wound care dressings and products in the neonatal and pediatric populations should be established to address specific concerns regarding wound management in these populations. Future Directions: The creation and implementation of evidence-based guidelines for the treatment of common wounds in the neonatal and pediatric populations is essential. In addition to an evaluation of currently marketed wound care dressings and products used in the adult population, newer wound care technologies should also be evaluated for use in neonates and children. In addition, further investigation of the specific pathophysiology of wound healing in neonates and children is indicated to promote the development of wound care dressings and products with specific applications in these populations.

Wound care is expensive and can cause immeasurable stress and inconvenience to patients and their significant others. It is therefore in the best interest of the patient, their significant others and the NHS as a whole that wounds are expertly assessed, managed and healed in the quickest timeframe possible. Nurses play a pivotal role in the process of accurate holistic wound assessment, evaluation and treatment. This article aims to help further develop and enhance both professional and clinical wound care assessment and evaluation skills. Pertinent wound care literature is critically reviewed and the crucial nature and important components of comprehensive wound assessment for facilitating the highest possible quality wound care to patients are presented alongside recommendations regarding how the enhanced knowledge and skills could be applied into everyday wound care practice.

Atelocollagen sponge and recombinant basic fibroblast growth factor combination therapy for resistant wounds with deep cavities.

2005-05-01

Recent advances in bioengineering have introduced materials that enhance wound healing. Even with such new tools, some deep ulcers surrounded by avascular tissues, including bone, tendon, and fascia, are resistant to various therapies and easily form deep cavities with loss of subcutaneous tissue. Atelocollagen sponges have been used as an artificial dermis to cover full-thickness skin defects. Topical recombinant human basic fibroblast growth factor has been introduced as a growth factor to induce fibroblast proliferation in skin ulcers. We applied these materials in combination in two patients with deep resistant wounds: one with a cavity reaching the mediastinum through a divided sternum and one with deep necrotic wounds caused by electric burns. These wounds did not respond to the topical basic fibroblast growth factor alone. In contrast, the combination therapy closed the wounds rapidly without further surgical treatment. This combination therapy is a potent treatment for resistant wounds with deep cavities.

Abstract Background Adolescent boys (aged 10–19 years) constitute the majority of voluntary medical male circumcision (VMMC) clients in sub-Saharan Africa. They are at higher risk of postoperative infections compared to adults. We explored adolescents’ wound-care knowledge, self-efficacy, and practices after VMMC to inform strategies for reducing the risks of infectious complications postoperatively. Methods Quantitative and qualitative data were collected in South Africa, Tanzania, and Zimbabwe between June 2015 to September 2016. A postprocedure survey was conducted approximately 7–10 days after VMMC among male adolescents (n = 1293) who had completed a preprocedure survey; the postprocedure survey assessed knowledge of proper wound care and wound-care self-efficacy. We also conducted in-depth interviews (n = 92) with male adolescents 6–10 weeks after the VMMC procedure to further explore comprehension of providers’ wound-care instructions as well as wound-care practices, and we held 24 focus group discussions with randomly selected parents/guardians of the adolescents. Results Adolescent VMMC clients face multiple challenges with postcircumcision wound care owing to factors such as forgetting, misinterpreting, and disregarding provider instructions. Although younger adolescents stated that parental intervention helped them overcome potential hindrances to wound care, parents and guardians lacked crucial information on wound care because most had not attended counseling sessions. Some older adolescents reported ignoring symptoms of infection and not returning to the clinic for review when an adverse event had occurred. Conclusions Increased involvement of parents/guardians in wound-care counseling for younger adolescents and in wound-care supervision, alongside the development of age-appropriate materials on wound care, are needed to minimize postoperative complications after VMMC.

To test the feasibility and effectiveness of using mobile phone text messaging to reinforce learning and the practice of diabetic foot care in a developing country. Ongoing learning reinforcement (2-3 times weekly) by text messaging followed an informal class on diabetic foot care in a community clinic setting. Subjects with cell phone access and no history of diabetic foot wounds or current wounds were recruited for participation (N = 225). Foot examinations and pretesting by survey occurred just before patients departed the clinic; the posttest survey and a final foot examination occurred 12 weeks later. The survey included basic demographic items along with items to measure knowledge and current foot care practices. One sample t tests (raw scores) and Wilcoxon signed-rank tests compared knowledge and practice before and after intervention. Initially, a majority of the sample (76%) reported poor levels of foot care. After 12 weeks <1% reported poor foot care practices. Statistical testing showed significant gains in knowledge (by score and level) and nearly unanimous compliance with daily foot examination. Mobile phone text messaging is an economical, feasible, and effective method for educators to improve diabetic self-care, even in a developing country. © 2017 John Wiley & Sons Australia, Ltd.

Health care professionals responsible for patients with complex wounds need a particular level of expertise and education to ensure optimum wound care. However, uniform education for those working as wound care nurses is lacking. We aimed to reach consensus among experts from six European countries as to the competencies for specialised wound care nurses that meet international professional expectations and educational systems. Wound care experts including doctors, wound care nurses, lecturers, managers and head nurses were invited to contribute to an e-Delphi study. They completed online questionnaires based on the Canadian Medical Education Directives for Specialists framework. Suggested competencies were rated on a 9-point Likert scale. Consensus was defined as an agreement of at least 75% for each competence. Response rates ranged from 62% (round 1) to 86% (rounds 2 and 3). The experts reached consensus on 77 (80%) competences. Most competencies chosen belonged to the domain 'scholar' (n = 19), whereas few addressed those associated with being a 'health advocate' (n = 7). Competencies related to professional knowledge and expertise, ethical integrity and patient commitment were considered most important. This consensus on core competencies for specialised wound care nurses may help achieve a more uniform definition and education for specialised wound care nurses. © 2013 The Authors.

Telemedicine in wound care is an evolving method of information technology and telecommunication designed to provide health care at a distance. Given the visual nature of wound care, telemedicine has many potential applications within this field. The authors will review the current status of wound care and telemedicine. A comprehensive literature review of articles published on telemedicine in wound care was performed. Articles were selected for their relevance to wound healing and then reviewed for their discussion on the potential applications, benefits, and limitations to telemedicine in wound care. The CICAT network data were reviewed including 5,794 patients between January 2005 and October 2015. Clinical efficacy and medicoeconomic results were analyzed. Current literature suggests a myriad of potential benefits of telemedicine in wound care, often citing increased access to professional expertise in remote and rural settings, as well as cost savings. The CICAT wound network in France analyzed wounds, which were principally pressure ulcers (44%), leg ulcers (24%), and diabetic foot ulcers (8%). Results demonstrated 75% of wounds improved or healed, a 72% reduction in the number of hospitalizations, and 56% reduction in ambulance transfers to wound healing centers. There is an increasing demand for assistance from professionals not specialized in wound healing, facing complex wounds. The goal is to enable the spread of expertise beyond major medical centers. Several limitations and barriers to the application of telemedicine in all settings are evident, including over diagnosis, dependence on a functional telecommunication system, and various legal aspects. The CICAT network in France provides an example of a how telemedicine may be of benefit in wound care, although it is important to note that in other countries, such as the United States, legal constraints and credentialing concerns may make telemedicine extremely complicated.

2018-04-24

Primary care health professionals, especially family physicians, see a variety of wounds, and yet-despite the frequency of providing wound care-many family physicians do not feel confident in wound care management. This is partly due to a lack of formal wound education in Family Medicine programs. While there are numerous electronic wound care resources available in the UK and North America, none were identified that address the specific need in supporting clinical decision-making in wound dressing selection. At the same time, healthcare providers are increasingly using technology in personal and professional contexts, and a logical extension is to use technology for knowledge translation strategies. This work developed a prototype mobile health software application named WounDS, designed to support clinical decision-making in selecting wound dressings. This article presents the development and evaluation plan for the WounDS app. WounDS has been developed on the iOS platform. The primary specification included ease of use, in that one of the primary influences in user adoption would be the ability to receive a wound dressing recommendation in under 30 seconds and under 5 taps on the screen. The WounDS app guides users through a series of binary decisions for assessing the wound and provides a wound dressing recommendation. The selection algorithm is based in best practices using the Wound Bed Preparation Paradigm. Current work is underway to examine the implementation needs for WounDS to be most effectively utilized and to pilot test its feasibility and use in clinical care. Data will be collected through user trials, focus groups, and user metadata will be collected within the app. Optimizing these preconditions will enable a subsequent phase of study to determine effects on clinical decision-making and clinical outcomes. WounDS is designed for knowledge translation, use of technology in clinical decision-making, and continuity of care. The benefits of WounDS include the potential to improve healthcare providers' competency in wound management and to improve wound healing through better alignment with evidence-based best practices in wound dressing selection, consistency in care from primary to community care, and subsequent downstream impacts in quality of life for patients. ©Scott Jordan, Jane McSwiggan, Joanne Parker, Gayle A.

2014-06-01

This study aimed to establish the prevalence and aetiology of wounds, allowing an insight into the management of wound care, the use of dressings and the nursing time allocated to the provision of wound care in a community setting in Ireland. A cross-sectional survey was used, with data collected on all clients in the community who received treatment from public health nurses or community registered general nurses for wound care over a 1-week period in April 2013. A 98.9% response rate was realised, and 188 people were identified as having wounds, equating to a crude prevalence of 5% of the active community nursing caseload. A total of 60% (n=112) had leg ulcers, 22% (n=42) had pressure ulcers, 16% (n=30) had an acute wound (surgical or traumatic wounds), 1% (n=2) had a diabetic foot wound and a further 1% (n=2) had wounds of other aetiologies. The mean duration of wounds was 5.41 months. A total of 18% of wounds were identified as infected; however, 60% (n=112) of wounds had antimicrobial products in use as either a primary or secondary dressing. The study established that there is a significant prevalence of wounds in this community care area. There was absence of a clinical diagnosis in many cases, and evidence of inappropriate dressing use, risking an increase in costs and a decrease in good clinical outcomes. It also highlighted the importance of ongoing education and auditing in the provision of wound care.

Skin wounds are associated with significant morbidity and mortality. Data are, however, not readily available for benchmarking, to allow prognostic evaluation, and to suggest when involvement of wound-healing experts is indicated. We, therefore, conducted an observational cohort study to investigate wound healing and all-cause mortality associated with different types of skin wounds. Consecutive skin wound patients who received wound care by home-care nurses from January 2010 to December 2011 in a district in Eastern Denmark were included in this study. Patients were followed until wound healing, death, or the end of follow-up on December 2012. In total, 958 consecutive patients received wound care by home-care nurses, corresponding to a 1-year prevalence of 1.2% of the total population in the district. During the study, wound healing was achieved in 511 (53.3%), whereas 90 (9.4%) died. During the first 3 weeks of therapy, healing was most likely to occur in surgical wounds (surgical vs. other wounds: adjusted hazard ratio [AHR] 2.21, 95% confidence interval 1.50-3.23), while from 3 weeks to 3 months of therapy, cancer wounds, and pressure ulcers were least likely to heal (cancer vs. other wounds: AHR 0.12, 0.03-0.50; pressure vs. other wounds: AHR 0.44, 0.27-0.74). Cancer wounds and pressure ulcers were further associated with a three times increased probability of mortality compared with other wounds (cancer vs. other wounds: AHR 3.19, 1.35-7.50; pressure vs. other wounds: AHR 2.91, 1.56-5.42). In summary, the wound type was found to be a significant predictor of healing and mortality with cancer wounds and pressure ulcers being associated with poor prognosis. © 2015 by the Wound Healing Society.

Belcher, Judy

In the current healthcare environment, clinicians are increasingly under pressure to use wound care products that are cost effective. This includes products that can be used in a variety of wounds to achieve different outcomes, depending on the wound-bed requirements. Medical-grade honey has emerged as a product that can achieve a variety of outcomes within the wound and is safe and easy to use. This article reviews the use of a medical-grade honey, with a view to including it on the wound care formulary in both primary and secondary care. It featured in a poster presentation at the Wounds UK conference at Harrogate in 2011.

Palliative management of pressure ulcers and malignant wounds in patients with advanced illness.

McDonald, Amy; Lesage, Pauline

2006-04-01

Pressure ulcers and malignant wounds are prevalent in populations with advanced illness. In these populations, the goals of care may shift from a primary focus on healing to a focus on wound management, palliation and comfort. Many complications associated with these wounds must be palliated. This review explores the palliative approach to managing pressure ulcers and malignant wounds in patients with advanced illness. A comprehensive search of MEDLINE, CINAHL, and Cochrane Databases for articles addressing wound management and palliation was performed. We also reviewed online wound care resources and textbooks related to the field. The key to good wound care is prevention if possible, ongoing wound assessment, correct choice of dressing and use of available adjuvant therapies. The ultimate goals of palliative wound care are to control pain, to manage infection, odor, bleeding, and exudate, and to maintain a good quality of life for the patient and caregiver.

Using wound care algorithms: a content validation study.

Valid and reliable heuristic devices facilitating optimal wound care are lacking. The objectives of this study were to establish content validation data for a set of wound care algorithms, to identify their associated strengths and weaknesses, and to gain insight into the wound care decision-making process. Forty-four registered nurse wound care experts were surveyed and interviewed at national and regional educational meetings. Using a cross-sectional study design and an 83-item, 4-point Likert-type scale, this purposive sample was asked to quantify the degree of validity of the algorithms' decisions and components. Participants' comments were tape-recorded, transcribed, and themes were derived. On a scale of 1 to 4, the mean score of the entire instrument was 3.47 (SD +/- 0.87), the instrument's Content Validity Index was 0.86, and the individual Content Validity Index of 34 of 44 participants was > 0.8. Item scores were lower for those related to packing deep wounds (P < .001). No other significant differences were observed. Qualitative data analysis revealed themes of difficulty associated with wound assessment and care issues, that is, the absence of valid and reliable definitions. The wound care algorithms studied proved valid. However, the lack of valid and reliable wound assessment and care definitions hinders optimal use of these instruments. Further research documenting their clinical use is warranted. Research-based practice recommendations should direct the development of future valid and reliable algorithms designed to help nurses provide optimal wound care.

French national wound management survey: choice criteria of dressings.

PubMed

Meaume, Sylvie; Barrois, Brigitte; Faucher, Nathalie

Across Europe, wound care management is organized differently, and in some countries such as the UK or Denmark, wound healing centres have been implemented. In France, a large number of health professionals are not sufficiently educated in wound care management during their vocational training. The rapid evolution of dressings has changed wound management practices and has given rise to new professional recommendations. This national survey was carried out in France in 2009, including 465 health professionals, to determine the criteria they use to choose a dressing and their habits of care with acute or chronic wounds. Around 73% of respondents were nurses and, on average, participants took care of 43 wounds per month. It was also found that 89% of the health professionals who took part prefer the sequential treatment of the wound based on its appearance. Regardless of whether the wound is acute or chronic, the priorities for wound care and the choice of dressing are the management of the exudate and the prevention or treatment of infection. These results put into evidence the adequacy of the recommendations by these practitioners and the good correlation between the choice of dressing and the local therapeutic goal. To reach the same level of expertise, the professional training for health professionals who are less frequently involved in wound care is necessary.

A guide to wound managment in palliative care.

Wound management in palliative patients is often a very challenging area of care. There are many unique issues that can combine to produce complicated wound management scenarios, including the types of wounds and wound symptoms most commonly affecting palliative care patients, as well as the presence of concurrent disease and associated treatment. Problems exist with the availability of suitable dressings and balancing life expectancy with the goals of wound care. A significant, and possibly under-recognized, issue is the emotional and social distress experienced by these patients, which can be directly attributed to their wound. These problems must all be recognized and addressed in order to manage wounds effectively in this patient population. This article aims to explore these issues and offer advice on the management of wound-related symptoms, with the ultimate goal of improving patients' quality of life.

The Internet and the World Wide Web have revolutionised communication and provide a unique forum for the exchange of information. It has been proposed that the Internet has given the public more access to medical information resources and improved patient education. This study assessed the impact of the Internet on the availability of information on wound care management. The search phrases 'wound care', 'wound healing' and 'wounds' were analysed using a powerful Metacrawler search engine (www.go2net.com). Web site access was classified according to the target audience (wound-care specialists, other health professionals, patients) and the author (societies, institutions or commercial companies). The largest proportion of web sites were commercially based (32%). Of the total number, 23% specifically targeted patients, mostly by advertising. Only 20% were aimed at wound specialists. Extensive surfing was required to obtain wound-care information, and objective information sites were under-represented. Regulated, easily accessible, objective information sites on wound-healing topics are needed for improved patient education and to balance the existing commercial bias.

Nutrition in Wound Care Management: A Comprehensive Overview.

PubMed

Quain, Angela M; Khardori, Nancy M

2015-12-01

Wound care is a multidisciplinary specialty requiring many physiologic and immunologic processes as well as physical, social, and societal factors to achieve successful wound closure. Most wounds are treated with combinations of antimicrobials, protective barriers, and topical growth agents, including skin and biologic grafts.The role of nutrition in wound healing may be overlooked in the wound care patient. Like the specialty, it is often multifaceted, with many nutritional components playing a variety of roles in the wound healing process. Suboptimal nutrition can alter immune function, collagen synthesis, and wound tensile strength, all of which are essential in the wound healing process. It is also important to remember that not all wounds are equal: a burn is different from a diabetic foot ulcer, which is different from a pressure ulcer. Nonetheless, nutrition is a common denominator for all wound patients, and what is studied in 1 wound population is often relevant in another. Due to the complexities of monitoring and measuring both wound healing and dietary intake, randomized, controlled trials of wound care patients are difficult to conduct, and much of the data concerning nutrition in wound care relies on combined supplements. In summary, it appears that some nutrients are necessary only if deficient, whereas others may become conditionally essential and serve a therapeutic role. All of the nutrients discussed should be viewed as a component of a broader, complete diet. This article is a summary of wound healing and the roles of a variety of macronutrients and micronutrients in the process.

Use of topical haemoglobin on sloughy wounds in the community setting.

PubMed

Bateman, Sharon Dawn

2015-09-01

This evaluation aimed to determine whether the use of a haemoglobin spray solution expedited sloughy wound healing. A descriptive evaluation was undertaken within a community setting exploring 25 patients presenting with sloughy healing and non-healing wounds, and the effects of 8 topically administered haemoglobin treatments over a 4-week period. Standard wound cleansing and dressing management were continued, with no changes to pre-evaluation regimens, and care being provided by the patients themselves or by a carer. Data were collected weekly with regard to primary outcomes of slough reduction, wound surface area reduction, patient ease of use (self-care), and overall product experience. At 4 weeks, all wounds demonstrated positive measured endpoints of slough elimination and continued wound-size reduction. Patients and carers found the product easy to use (self-caring) with an overall positive wound care experience. The administration of a haemoglobin spray solution on patients presenting with sloughy wounds resulted in positive healing outcomes of slough elimination and wound reduction alongside positive self-care and product satisfaction. Continued evaluation is recommended to build upon the evidence of this form of treatment.

Estimating the applicability of wound care randomized controlled trials to general wound-care populations by estimating the percentage of individuals excluded from a typical wound-care population in such trials.

To determine the percentage of individuals that would be excluded from wound care randomized controlled trials (RCTs) as a surrogate for applicability to general populations. A representative sample of wound-care RCTs was selected from the literature in the past 10 years. Exclusion criteria from the trials were evaluated, and prevalence values for each excluded condition were obtained from a large wound-care population, as well as from the literature. The percentage of patients excluded on this basis was calculated. Seventeen RCTs testing "high-technology" wound-care products were evaluated. : Patients in the trials were treated for ulcers (venous, diabetic foot, and pressure ulcers). A percentage of patients in the study population were excluded for each RCT. More than 50% of the study population would have been excluded in 15 of the 17 RCTs. When less clinically relevant exclusion criteria were removed, 14 of 17 RCTs would still have excluded between 25% and 50% of the study population. The results raise serious questions regarding the applicability of these RCTs to wound-care populations.

Innovation and wound healing.

Innovation in medicine requires unique partnerships between academic research, biotech or pharmaceutical companies, and health-care providers. While innovation in medicine has greatly increased over the past 100 years, innovation in wound care has been slow, despite the fact that chronic wounds are a global health challenge where there is a need for technical, process and social innovation. While novel partnerships between research and the health-care system have been created, we still have much to learn about wound care and the wound-healing processes.

Vowden, K; Vowden, P; Posnett, J

2009-03-01

To estimate the resource costs of providing wound care for the 488,000 catchment population of the Bradford and Airedale primary care trust (PCT). A wound survey was carried out over a one-week period in March 2007 covering three hospitals in two acute trusts, district nurses, nursing homes and residential homes within the geographical area defined by the PCT. The survey included information on the frequency of dressing change, treatment time and district nurse travel time. The resource costs of wound care in the PCT were estimated by combining this information with representative costs for the UK National Health Service and information on dressing spend. Prevalence of patients with a wound was 3.55 per 1000 population. The majority of wounds were surgical/trauma (48%), leg/foot (28%) and pressure ulcers (21%). Prevalence of wounds among hospital inpatients was 30.7%. Of these, 11.6% were pressure ulcers, of which 66% were hospital-acquired. The attributable cost of wound care in 2006-2007 was pounds 9.89 million: pounds 2.03 million per 100,000 population and 1.44% of the local health-care budget. Costs included pounds 1.69 million spending on dressings, 45.4 full-time nurses (valued at pounds 3.076 million) and 60-61 acute hospital beds (valued at pounds 5.13 million). The cost of wound care is significant. The most important components are the costs of wound-related hospitalisation and the opportunity cost of nurse time. The 32% of patients treated in hospital accounted for 63% of total costs. Putting in place care pathways to avoid hospitalisation and avoiding the development of hospital-acquired pressure ulcers and other wound complications are important ways to reduce costs.

To examine the feasibility and acceptance of teledermatology for wound management for patients with leg ulcers by home care nurses and evaluate the reduction of costs and the acceptance of teledermatology by patients and home care nurses. Case series of telemonitored patients with leg ulcers including cost-effectiveness analysis. Home monitoring by home care nurses. Sixteen patients with 45 leg ulcers of different origin were included. After an initial outpatient visit when the leg ulcers were assessed and classified, teledermatological follow-up was done by home care nurses. Relevant clinical information and 1 to 4 digital images of the wound and surrounding skin were transmitted weekly via a secure Web site to an expert at the wound care center, who assessed the wound and made therapeutic recommendations. Of the 707 images transmitted for teleconsultation, in 644 (89%) the quality of the images was excellent or sufficient and the experts were confident in giving therapeutic recommendations. Of the 45 ulcers, 32 (71%) decreased in size and 14 (31%) healed completely, whereas 10 of the 45 ulcers (22%) increased slightly in size despite the teledermatological monitoring. In 3 ulcers (7%), no measurement was possible owing to the overly large size of the ulcers. The acceptance of telemedicine was very good by most patients. Of 15 home care nurses working in the district, 7 were very satisfied with teledermatological monitoring of wound care. There was a reduction of 46% in transportation costs for the insurance companies as well as for the patients owing to a significant decrease in the number of visits to general physicians or the wound care center. The acceptance of teledermatological monitoring of wound care was very high by patients, home care nurses, and wound experts. Decreased health care costs by reducing the number of visits to wound care centers or specialist physicians and improvement in quality of life for patients with leg ulcers using telemedicine seems possible. Teledermatology offers great potential for long-term wound care.

Chlorhexidine hexametaphosphate as a wound care material coating: antimicrobial efficacy, toxicity and effect on healing.

2016-08-01

In this study, chlorhexidine hexametaphosphate (CHX-HMP) is investigated as a persistent antimicrobial coating for wound care materials. CHX-HMP was used as a wound care material coating and compared with chlorhexidine digluconate materials with respect to antimicrobial efficacy, toxicity and wound closure. Antimicrobial efficacy at day 1, 3 and 7 was observed with experimental and commercial materials. CHX-HMP coated materials had less toxic effect on human placental cells than commercial chlorhexidine dressings. CHX-HMP in pluronic gel did not delay healing but reduced wound colonization by E. faecalis. CHX-HMP could become a useful component of wound care materials with sustained antimicrobial efficacy, lower toxicity than chlorhexidine digluconate materials, and reduction in wound colonization without affecting closure.

PubMed

Tandler, Suzanne; Stephen-Haynes, Jackie

2017-06-22

This article defines fungating wounds and considers the underlying cause, location and presentation. The clinical challenges presented by fungating wounds are discussed, with reference to evidence-based care delivery. This includes wound assessment, cleansing, debridement and management of malodour, infection, bleeding and exudate. Guidance on the use of wound management dressings is considered in relation to symptom management. The importance of clinical decision-making and educational preparation in the delivery of evidenced-based care for those with fungating wounds is emphasised. A conclusion is made that the clinician can support the patient with a fungating wound by the delivery of evidenced-based care.

From October 1, 2006, to September 30, 2007, a "good wound care" intervention was implemented at a rural Veterans Affairs facility to prevent amputations in veterans with diabetes and foot ulcers. The study protocol included a template with foot ulcer variables embedded in the electronic medical record to facilitate data collection, support clinical decision making, and improve ordering and medical coding. The intervention group showed significant differences in complete documentation of good wound care compared to the historic control group (χ = 15.99, P < .001), complete documentation of coding for diagnoses and procedures (χ = 30.23, P < .001), and complete documentation of both good wound care and coding for diagnoses and procedures (χ = 14.96, P < .001). An electronic wound care template improved documentation of evidence-based interventions and facilitated coding for wound complexity and procedures.

Diabetic foot ulcers affect millions of people in the United States of America and impose tremendous medical, psychosocial and financial loss or burden. Negative pressure wound therapy (NPWT) is generally well tolerated and appears to stimulate a robust granulation tissue response compared with other wound healing modalities. This device may be a cost-effective adjunctive wound healing therapy. This literature review will focus on the clinical outcome of diabetic foot ulcers treated with NPWT, its implication in the transition from acute care to home care, factors that might influence clinical outcomes in home care as well as quality-of-life aspects in these patients. Patient care for diabetic foot ulceration is complex and necessitates multiprofessional collaboration to provide comprehensive wound care. It is clear that when we strive for limb preservation in this most high-risk population, it is important to have an available versatile, efficacious wound healing modality. There is a need for an easy transition from acute care to home care. Resources need to be combined in a collaborative and synergistic fashion to allow patient to perform many daily living activities while receiving the potential benefits of an advanced wound healing modality.

Improved wound management by regulated negative pressure-assisted wound therapy and regulated, oxygen- enriched negative pressure-assisted wound therapy through basic science research and clinical assessment.

PubMed

Regulated negative pressure-assisted wound therapy (RNPT) should be regarded as a state-of-the-art technology in wound treatment and the most important physical, nonpharmaceutical, platform technology developed and applied for wound healing in the last two decades. RNPT systems maintain the treated wound's environment as a semi-closed, semi-isolated system applying external physical stimulations to the wound, leading to biological and biochemical effects, with the potential to substantially influence wound-host interactions, and when properly applied may enhance wound healing. RNPT is a simple, safe, and affordable tool that can be utilized in a wide range of acute and chronic conditions, with reduced need for complicated surgical procedures, and antibiotic treatment. This technology has been shown to be effective and safe, saving limbs and lives on a global scale. Regulated, oxygen-enriched negative pressure-assisted wound therapy (RO-NPT) is an innovative technology, whereby supplemental oxygen is concurrently administered with RNPT for their synergistic effect on treatment and prophylaxis of anaerobic wound infection and promotion of wound healing. Understanding the basic science, modes of operation and the associated risks of these technologies through their fundamental clinical mechanisms is the main objective of this review.

Biofilm inhibitory and eradicating activity of wound care products against Staphylococcus aureus and Staphylococcus epidermidis biofilms in an in vitro chronic wound model.

Although several factors contribute to wound healing, bacterial infections and the presence of biofilm can significantly affect healing. Despite that this clearly indicates that therapies should address biofilm in wounds, only few wound care products have been evaluated for their antibiofilm effect. For this reason, we developed a rapid quantification approach to investigate the efficacy of wound care products on wounds infected with Staphylococcus spp. An in vitro chronic wound infection model was used in which a fluorescent Staph. aureus strain was used to allow the rapid quantification of the bacterial burden after treatment. A good correlation was observed between the fluorescence signal and the bacterial counts. When evaluated in this model, several commonly used wound dressings and wound care products inhibited biofilm formation resulting in a decrease between one and seven log CFU per biofilm compared with biofilm formed in the absence of products. In contrast, most dressings only moderately affected mature biofilms. Our model allowed the rapid quantification of the bacterial burden after treatment. However, the efficacy of treatment varied between the different types of dressings and/or wound care products. Our model can be used to compare the efficacy of wound care products to inhibit biofilm formation and/or eradicate mature biofilms. In addition, the results indicate that treatment of infected wounds should be started as soon as possible and that novel products with more potent antibiofilm activity are needed. © 2013 The Society for Applied Microbiology.

After Super Typhoon Haiyan, a category 5 tropical cyclone, insufficient resources were available for medical management. Many patients in the Philippines were wounded as a result of the disaster. We examined the prevalence, risk factors, and consequences of disaster-related wounds and wound infection in the post-disaster period. We performed a retrospective review of consecutive patients admitted to a Korean Disaster Relief Team clinic at St. Paul's Hospital, Tacloban City, Republic of Philippines, between December 9 and 13, 2013. Traumatic injury patients were included; patients not exhibiting a wound were excluded. Of the 160 patients enrolled in the study, 71 (44.4%) had infected wounds. There were no significant differences in the age, sex, past medical history, wound site, wound depth, injury mechanism, or inducer of injury between the uninfected and infected groups. In the univariate analysis, a foreign-body-contaminated wound, a chronic wound, elapsed time from injury to medical contact, an inadequately cared for wound, and need for subsequent wound management were associated with wound infection (P<0.05). The multivariate analysis revealed that foreign body contamination and having an inadequately cared for wound were associated with wound infection (odds ratio [OR]: 10.12, 95% confidence interval [CI]: 3.59-28.56; OR: 3.51, 95% CI: 1.07-11.51, respectively). In the post-disaster situation, many wound infections required definitive care. Wound infection was associated with inadequately cared for wounds and foreign-body-contaminated wounds.

To incorporate an international and multidisciplinary consensus in the determination of the research and education priorities for wound healing and tissue repair. A compelling reason for the study is the lack of an agreed list of priorities for wound care research and education. Furthermore, there is a growth in the prevalence of chronic wounds, a growth in wound care products and marketing, and an increase in clinician attendance at conferences and education programmes. The study used a survey method. A four-round eDelphi technique was used to collect responses from an international population of health professionals across 24 countries. Responses were obtained from 360 professionals representing many health care settings. The top education priorities related to the standardisation of all foundation education programmes in wound care, the inclusion of wound care in all professional undergraduate and postgraduate education programmes, selecting dressings and the prevention of pressure ulcers. The top research priorities related to the dressing selection, pressure ulcer prevention and wound infection. conclusion: Professionals from different backgrounds and countries who are engaged in wound management share a common set of priorities for research and education. Most notably, the priorities identified relate to long-established clinical challenges in wound care and underpin the principles of good patient care practices. The priorities are closely allied to an ageing population and identify many challenges ahead for practitioners engaged in wound management services. The provision of wound care is a major investment of health service resources and remains a clinical challenge today. Research is essential to building evidence-based practice and fundamental to development of quality in standards of practice; education is central to achieving competence to deliver effective care. The determination of research and education priorities is therefore an absolute requirement in developing services. © 2011 Blackwell Publishing Ltd.

Chronic wounds cost the Australian health system at least US$2·85 billion per year. Wound care services in Australia involve a complex mix of treatment options, health care sectors and funding mechanisms. It is clear that implementation of evidence-based wound care coincides with large health improvements and cost savings, yet the majority of Australians with chronic wounds do not receive evidence-based treatment. High initial treatment costs, inadequate reimbursement, poor financial incentives to invest in optimal care and limitations in clinical skills are major barriers to the adoption of evidence-based wound care. Enhanced education and appropriate financial incentives in primary care will improve uptake of evidence-based practice. Secondary-level wound specialty clinics to fill referral gaps in the community, boosted by appropriate credentialing, will improve access to specialist care. In order to secure funding for better services in a competitive environment, evidence of cost-effectiveness is required. Future effort to generate evidence on the cost-effectiveness of wound management interventions should provide evidence that decision makers find easy to interpret. If this happens, and it will require a large effort of health services research, it could be used to inform future policy and decision-making activities, reduce health care costs and improve patient outcomes. © 2015 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

Diabetic foot ulcers are the consequence of multiple factors including peripheral neuropathy, decreased blood supply, high plantar pressures, etc., and pose a significant risk for morbidity, limb loss and mortality. The critical aspects of the wound healing mechanism and host physiological status in patients with diabetes necessitate the selection of an appropriate treatment strategy based on the complexity and type of wound. In addition to systemic antibiotics and surgical intervention, wound care is considered to be an important component of diabetic foot ulcer management. This article will focus on the use of different wound care materials in diabetic foot. From a clinical perspective, it is important to decide on the wound care material depending on the type and grade of the ulcer. This article will also provide clinicians with a simple approach to the choice of wound care materials in diabetic foot ulcer. PMID:25126400

This study sought to explore patients' and clinicians' perceptions and experiences with the provision of standard care by a home care nurse alone or by a multidisciplinary wound care team. The interviews were conducted using an in-depth semi structured format; following a funnel idea of starting out broad and narrowing down, ensuring that all the necessary topics were covered by the end of the interview. A purposive sample of 16 patients with different wound types were interviewed to ensure that the data would reflect the range and diversity of treatment and care experience. To reflect the diversity of experiences 12 clinicians from various clinical backgrounds were interviewed. Based on the analysis of the interviews, there are four overarching themes: wound care expertise is required across health-care sectors, psychosocial needs of patients with chronic wounds are key barriers to treatment concordance, structured training, and a well-coordinated multidisciplinary team approach. Results of this qualitative study identified different barriers and facilitators that affect the experiences of community-based wound care.

Moulin, Véronique J.; Dubé, Jean; Rochette-Drouin, Olivier; Lévesque, Philippe; Gauvin, Robert; Roberge, Charles J.; Auger, François A.; Goulet, Daniel; Bourdages, Michel; Plante, Michel; Germain, Lucie

2012-01-01

Background After human epidermis wounding, transepithelial potential (TEP) present in nonlesional epidermis decreases and induces an endogenous direct current epithelial electric field (EEF) that could be implicated in the wound re-epithelialization. Some studies suggest that exogenous electric stimulation of wounds can stimulate healing, although the mechanisms remain to be determined. The Problem Little is known concerning the exact action of the EEF during healing. The mechanism responsible for TEP and EEF is unknown due to the lack of an in vitro model to study this phenomenon. Basic Science Advances We carried out studies by using a wound created in a human tissue-engineered skin and determined that TEP undergoes ascending and decreasing phases during the epithelium formation. The in vitro TEP measurements over time in the wound were corroborated with histological changes and with in vivo TEP variations during porcine skin wound healing. The expression of a crucial element implicated in Na+ transport, Na+/K+ ATPase pumps, was also evaluated at the same time points during the re-epithelialization process. The ascending and decreasing TEP values were correlated with changes in the expression of these pumps. The distribution of Na+/K+ ATPase pumps also varied according to epidermal differentiation. Further, inhibition of the pump activity induced a significant decrease of the TEP and of the re-epithelization rate. Clinical Care Relevance A better comprehension of the role of EEF could have important future medical applications regarding the treatment of chronic wound healing. Conclusion This study brings a new perspective to understand the formation and restoration of TEP during the cutaneous wound healing process. PMID:24527285

Repeated Use of Immersive Virtual Reality Therapy to Control Pain during Wound Dressing Changes in Pediatric and Adult Burn Patients

Faber, Albertus W.; Patterson, David R.; Bremer, Marco

2012-01-01

Objective The current study explored whether immersive virtual reality continues to reduce pain (via distraction) during more than one wound care session per patient. Patients: Thirty six patients aged 8 to 57 years (mean age of 27.7 years), with an average of 8.4% total body surface area burned (range .25 to 25.5 TBSA) received bandage changes, and wound cleaning. Methods Each patient received one baseline wound cleaning/debridement session with no-VR (control condition) followed by one or more (up to seven) subsequent wound care sessions during VR. After each wound care session (one session per day), worst pain intensity was measured using a Visual Analogue Thermometer (VAT), the dependent variable. Using a within subjects design, worst pain intensity VAT during wound care with no-VR (baseline, Day 0) was compared to pain during wound care while using immersive virtual reality (up to seven days of wound care during VR). Results Compared to pain during no-VR Baseline (Day 0), pain ratings during wound debridement were statistically lower when patients were in virtual reality on Days 1, 2 and 3, and although not significant beyond day 3, the pattern of results from Days 4, 5, and 6 are consistent with the notion that VR continues to reduce pain when used repeatedly. Conclusions Results from the present study suggest that VR continues to be effective when used for three (or possibly more) treatments during severe burn wound debridement. PMID:23970314

Previously, we have shown that extracellular basic pH plays a significant role in both the direct and indirect regulation of cellular processes in a wound; this in turn affects the wound-healing process. Several studies have demonstrated the importance of apoptosis modulation in the wound-healing process, especially in removing inflammatory cells and in inhibiting scar formation. However, the effects of extracellular basic pH on wound healing-related skin damage are yet to be examined. Therefore, we investigated the induction of accelerated apoptosis by extracellular basic pH in skin. Apoptosis-related protein levels were measured using an array kit, target protein expression levels were detected by immunostaining, lactate dehydrogenase was analyzed spectrophotometrically, and Annexin V levels were measured by fluorescence staining. Basic pH (8.40) strongly upregulated extrinsic apoptosis proteins (Fas, high temperature requirement A, and p21) and slightly upregulated intrinsic apoptosis proteins (cytochrome c, B-cell lymphoma 2 [Bcl-2], Bcl-2-associated death promoter, and Bcl-2-like protein 4) in a 3D human skin equivalent system. Moreover, basic pH (8.40) induced heat shock protein (HSP) 60 and 70. In addition, basic pH-exposed Fas- and HSP60-knockdown cells showed significantly decreased levels of apoptosis. Taken together, these results indicate that extracellular basic pH increases early-stage apoptosis through Fas/FasL via modulation of HSP60 and HSP70. © 2017 S. Karger AG, Basel.

Community nurses were involved in caring for 70.1% of patients with wounds, with 52.7% of wounds being treated in the patient's home. The largest proportion of wounds were surgical wounds (n=699, 41.5%), followed by leg and foot ulcers (n=629, 37.3%) and pressure ulcers (n=294, 17.4%). Diabetes and cancer were related to 15.1% and 9.7% of the wounds respectively. 41.9% of the wounds were on the lower leg. The primary and secondary dressings used the most were low/non-adherent dressings at 25.9% and 27.3% respectively.Almost half of the patients with a venous leg ulcer (46%) did not receive multilayer compression and 7% of patients with an arterial ulcer did; 23.6% of the leg and foot wounds were not assessed with a Doppler. Wounds represent a significant cause of morbidity in the general population.A systematic focus is necessary on effective and timely diagnosis, on ensuring treatment is appropriate to the cause and condition of the wound and on active measures to prevent complications.A number of initiatives have commenced in order to provide a effective and efficient wound care.

Leptospermum Honey for Wound Care in an Extremely Premature Infant.

PubMed

Esser, Media

2017-02-01

Neonatal wound care is challenging due to the fragility and vulnerable skin structure. Neonates are often left susceptible to the forces of their environment, leaving them open to infection when skin injury occurs. Leptospermum honey has been used successfully in adult patients, with evidence lacking in the neonatal population. This case demonstrates the management of a difficult-to-heal wound in a 23-week gestation infant. Selecting the proper treatment and products for wound healing is challenging, with little evidence-based research available for the treatment of neonatal wounds. Leptospermum honey and other adult-driven dressings have been used for neonatal wound care as well as other adult-driven dressings. This case demonstrates the benefits of Leptospermum honey as an option for neonatal wounds. This case presents the treatment and healing of an extensive wound of a 23-week gestation neonate using a hydrogel product initially and then transitioning to a Leptospermum honey dressing due to suboptimal healing. Results of this treatment included quick healing time, little to no scarring, and no loss of movement or function to the affected extremities. The incorporation of Leptospermum honey for wound care has the potential to promote faster wound healing, with less scarring in the neonatal population. Adult wound care principles have been applied in the face of a weak evidence base relating to neonatal-specific cases. There is a need for continued research related to moist wound healing in the neonatal population, with resulting product and practice recommendations.

Adjuvant use of acoustic pressure wound therapy for treatment of chronic wounds: a retrospective analysis.

PubMed

Cole, Pamela S; Quisberg, Jennifer; Melin, M Mark

2009-01-01

Small studies have indicated that the addition of acoustic pressure wound therapy (APWT) to conventional wound care may hasten healing of chronic wounds. We evaluated our early clinical experience using APWT as an adjunct to conventional wound care. The study was a retrospective chart review of consecutive patients receiving APWT in addition to conventional wound care in a hospital-based, primarily outpatient setting. Medical records of all patients treated with APWT between August 2006 and October 2007 were reviewed. Analysis included the 41 patients with 52 wounds who received APWT at least 2 times per week during the study period. Statistical comparisons were made for wound dimensions, tissue characteristics, and pain at start versus end of APWT. Thirty-eight percent of wounds (N = 20) healed completely with a mean 6.8 weeks of APWT. Median wound area and volume decreased significantly (88% [P < .0001] and 100% [P < .0001], respectively) from start to end of APWT. The proportion of wounds with greater than 75% granulation tissue increased from 26% (n = 12) to 80% (n = 41) (P < .0001), and normal periwound skin increased from 25% (n = 13) to 54% (n = 28) (P = .0001). Presence of greater than 50% fibrin slough decreased from 50% (n = 24) to 9% (n = 4) of wounds (P = .006). This early experience supplementing conventional wound care with APWT suggests it may promote healing in chronic wounds, where the ordered cellular and molecular processes leading to healing have stalled.

Macrophages are essential for tissue repair. They have a crucial role in cutaneous wound healing, participating actively in the inflammation phase of the process. Unregulated macrophage activation may, however, represent a source of excessive inflammation, leading to abnormal wound healing and hypertrophic scars. Our research group has shown that apoptotic endothelial and epithelial cells secrete MFG-E8, which has the ability to reprogram macrophages from an M1 (proinflammatory) to an M2 (anti-inflammatory, pro-repair) phenotype. Hence, we tested whether modulation of macrophage reprogramming would promote tissue repair. Using a mouse model of wound healing, we showed that the presence and/or addition of MFG-E8 favors wound closure associated with an increase in CD206-positive cells and basic fibroblast growth factor production in healing tissues. More importantly, adoptive transfer of ex vivo MFG-E8-treated macrophages promoted wound closure. We also observed that MFG-E8-treated macrophages produced basic fibroblast growth factor that is responsible for fibroblast migration and proliferation. Taken together, our results strongly suggest that MFG-E8 plays a key role in macrophage reprogramming in tissue healing through induction of an anti-inflammatory M2 phenotype and basic fibroblast growth factor production, leading to fibroblast migration and wound closure.

What Do Patients Want? Patient Preference in Wound Care

PubMed Central

Corbett, Lisa Q.; Ennis, William J.

2014-01-01

Patient preferences are statements made or actions taken by consumers that reflect their desirability of a range of health options. The concept occupies an increasingly prominent place at the center of healthcare reform, and is connected to all aspects of healthcare, including discovery, research, delivery, outcome, and payment. Patient preference research has focused on shared decisions, decisional aids, and clinical practice guideline development, with limited study in acute and chronic wound care populations. The wound care community has focused primarily on patient focused symptoms and quality of life measurement. With increasing recognition of wound care as a medical specialty and as a public health concern that consumes extensive resources, attention to the preferences of end-users with wounds is necessary. This article will provide an overview of related patient-centered concepts and begin to establish a framework for consideration of patient preference in wound care. PMID:25126474

This article represents a process paper describing the development, at our facility, of a wound care fellowship that was scheduled to begin in July of 2003. The proposed program is in no way a finished product or our statement of how the program must be. This article is presented as a call to wound care professionals for input, criticism, guidance, and--we hope--adoption and acceptance of wound care fellowships in some format in the future. After many years of work in this field, it has become apparent that without medical specialization wound care will never rise from its current status of part-time avocation to full-time occupation. After a brief background and description of the present status of wound care education, an initial curriculum, program objectives, and clinical rotation schedule are presented. We look forward to the day when this program will have been replaced with a fully accredited, readily accepted, board-certifiable fellowship program with all the rights and responsibilities afforded the other medical specialties.

Wound-Healing Peptides for Treatment of Chronic Diabetic Foot Ulcers and Other Infected Skin Injuries.

2017-10-18

As the incidence of diabetes continues to increase in the western world, the prevalence of chronic wounds related to this condition continues to be a major focus of wound care research. Additionally, over 50% of chronic wounds exhibit signs and symptoms that are consistent with localized bacterial biofilms underlying severe infections that contribute to tissue destruction, delayed wound-healing and other serious complications. Most current biomedical approaches for advanced wound care aim at providing antimicrobial protection to the open wound together with a matrix scaffold (often collagen-based) to boost reestablishment of the skin tissue. Therefore, the present review is focused on the efforts that have been made over the past years to find peptides possessing wound-healing properties, towards the development of new and effective wound care treatments for diabetic foot ulcers and other skin and soft tissue infections.

Wound Dressings and Comparative Effectiveness Data

Significance: Injury to the skin provides a unique challenge, as wound healing is a complex and intricate process. Acute wounds have the potential to move from the acute wound to chronic wounds, requiring the physician to have a thorough understanding of outside interventions to bring these wounds back into the healing cascade. Recent Advances: The development of new and effective interventions in wound care remains an area of intense research. Negative pressure wound therapy has undoubtedly changed wound care from this point forward and has proven beneficial for a variety of wounds. Hydroconductive dressings are another category that is emerging with studies underway. Other modalities such as hyperbaric oxygen, growth factors, biologic dressings, skin substitutes, and regenerative materials have also proven efficacious in advancing the wound-healing process through a variety of mechanisms. Critical Issues: There is an overwhelming amount of wound dressings available in the market. This implies the lack of full understanding of wound care and management. The point of using advanced dressings is to improve upon specific wound characteristics to bring it as close to “ideal” as possible. It is only after properly assessing the wound characteristics and obtaining knowledge about available products that the “ideal” dressing may be chosen. Future Directions: The future of wound healing at this point remains unknown. Few high-quality, randomized controlled trials evaluating wound dressings exist and do not clearly demonstrate superiority of many materials or categories. Comparative effectiveness research can be used as a tool to evaluate topical therapy for wound care moving into the future. Until further data emerge, education on the available products and logical clinical thought must prevail. PMID:25126472

Most of the skin disorders that occur in neonatal intensive care units are due in part to the immaturity and vulnerability of the neonatal skin. Various iatrogenic diagnostic and therapeutic procedures are also conducive to iatrogenic damage. This study was to review the neonates admitted to our neonatal intensive care unit who needed wound management, and to assess the most common skin injuries and wounds, and their aetiology. Data were extracted from medical records of neonates who needed wound management in our Neonatal Intensive Care Unit between January 31, 2012 and January 31, 2013. Information about gestational age, sex, birth weight, area of involvement, wound aetiology, and therapy were collected. Among the 211 neonates observed, wound management was required in 10 cases of diaper dermatitis, 7 epidermal stripping, 6 extravasation injuries, 5 pressure ulcers, 1 surgical wound and infection, 1 thermal burn, and 5 other lesions. International guidelines in neonatal wound care practice are not available, and further research concerns are clearly needed. Dressings and antiseptic agents should be chosen with great care for application to neonates, with particular attention to the prevention of adverse events in this sensitive population. Team work among dermatologists, neonatologists and nurses is crucial for the successful treatment of neonates.

If pharmaceutic modulation of scar formation does not improve the quality of the healing process over conventional healing, the surgeon must rely on personal skill and experience. Therefore a profound knowledge of wound healing based on experimental and clinical studies supplemented by postsurgical means of scar management and basic techniques of planning incisions, careful tissue handling, and thorough knowledge of suturing remain the most important ways to avoid abnormal scarring. This review summarizes the current experimental and clinical bases of surgical scar management.

Telemedicine (TM) is a new, rapidly evolving area and can be of great value in the provision of healthcare to remote and rural populations. Wound healing and wound management are prime candidates for TM. The treatment of skin ulcers requires frequent assessments of local wound status and adjustment of therapy. The availability of reasonably priced photographic equipment and quick electronic transfer of high-quality digital images should make the assessment of wound status by remote experts possible. Several studies showing the feasibility and the usefulness of teleconsultations in dermatology have already been described in the literature, and high accordance for diagnosis and treatment between face-to-face visits and teleconsultations has been reported. Some used digital photographs and sent the image and clinical data via the Internet to a wound care specialist (store and forward), whereas others used a webcam (televideoconferencing). Tele-wound care offers great potential for the future in chronic wound care. By reducing the need to travel long distances to the hospital or to consult with a physician, TM decreases the costs and improves the quality of life for patients with chronic wounds, while still maintaining high standards of wound care. The intent of TM is to reduce, in a clinically equivalent way, the number of visits to a specialized clinic, but not necessarily to eliminate all visits. Further well-designed research is necessary to understand how best to deploy TM services in healthcare.

: The purpose of the study was to evaluate the benefit of using pulsed radiofrequency energy (PRFE) therapy in the treatment of chronic pressure ulcers. : A retrospective analysis was performed using case series data from the Provant Wound Registry, which consists of demographic characteristics and wound healing outcomes for patients treated with the Provant Therapy System. : The analysis subset consisted of data from 39 distinct centers, including both residential and ambulatory care facilities. : The analysis included data from 89 patients. The majority of patients (89%) were cared for in residential facilities, whereas 11% of patients were cared for in ambulatory care facilities. : Specific outcomes that assessed wound healing between the initial time point and at the 4-week follow-up were as follows: percent wound surface area reduction (PWAR), proportion of wounds achieving 50% reduction or greater in wound surface area (50% PWAR), and the rate of wound healing (wound healing trajectory in centimeters squared per day). : Overall, there was a 51% median reduction in wound surface area (PWAR) after 4 weeks of PRFE therapy for wounds in the study, with 51% of wounds (56/110) achieving 50% reduction or greater in wound surface area (50% PWAR). Rate of healing measurements for the overall study group showed a median wound healing trajectory of 0.13 cm/d at 4 weeks. : Compared with historical controls and other studies using similar surrogate wound healing markers, these results suggest PRFE therapy is a beneficial adjuvant treatment option for healing chronic pressure ulcers.

Chronic wounds represent a significant burden to patients, health care professionals and the entire health care system. Regarding the healing process, wounds can be classified as acute or chronic wounds. A wound is considered chronic if healing does not occur within the expected period according to the wound etiology and localization. Chronic wounds can be classified as typical and atypical. The majority of wounds (95 percent) are typical ones, which include ischemic, neurotrophic and hypostatic ulcers and two separate entities: diabetic foot and decubital ulcers. Eighty percent of chronic wounds localized on lower leg are the result of chronic venous insufficiency, in 5-10 percent the cause is of arterial etiology, whereas the rest are mostly neuropathic ulcers. Chronic wounds significantly decrease the quality of life of patients by requiring continuous topical treatment, causing immobility and pain in a high percentage of patients. Chronic wounds affect elderly population. Chronic leg ulcers affect 0.6-3 percent of those aged over 60, increasing to over 5 percent of those aged over 80. Emergence of chronic wounds is a substantial socioeconomic problem as 1-2 percent of western population will suffer from it. This estimate is expected to rise due to the increasing proportion of elderly population along with the diabetic and obesity epidemic. It has been proved that chronic wounds account for the large proportion of costs in the health care system, even in rich societies. Socioeconomically, the management of chronic wounds reaches a total of 2-4 percent of the health budget in western countries. Treatment costs for some other diseases are not irrelevant, nor are the method and materials used for treating these wounds. Considering etiologic factors, a chronic wound demands a multidisciplinary approach with great efforts of health care professionals to treat it more efficiently, more simply and more painlessly for the patient, as well as more inexpensively for health care funds.

Management of minor acute cutaneous wounds: importance of wound healing in a moist environment.

PubMed

Korting, H C; Schöllmann, C; White, R J

2011-02-01

Moist wound care has been established as standard therapy for chronic wounds with impaired healing. Healing in acute wounds, in particular in minor superficial acute wounds - which indeed are much more numerous than chronic wounds - is often taken for granted because it is assumed that in those wounds normal phases of wound healing should run per se without any problems. But minor wounds such as small cuts, scraps or abrasions also need proper care to prevent complications, in particular infections. Local wound care with minor wounds consists of thorough cleansing with potable tap water or normal saline followed by the application of an appropriate dressing corresponding to the principles of moist wound treatment. In the treatment of smaller superficial wounds, it appears advisable to limit the choice of dressing to just a few products that fulfil the principles of moist wound management and are easy to use. Hydroactive colloid gels combining the attributes of hydrocolloids and hydrogels thus being appropriate for dry and exuding wounds appear especially suitable for this purpose - although there is still a lack of data from systematic studies on the effectiveness of these preparations. © 2010 The Authors.

To evaluate the effect of topical haemoglobin spray on treatment response and wound-closure rates in patients with chronic venous leg ulcers. A linear regression model was used to forecast healing outcomes over a 12-month period. Simulated data were taken from normal distributions based on post-hoc analysis of a 72-patient study in non-healing and worsening wounds (36 patients receiving standard care and 36 receiving standard care plus topical haemoglobin spray). Using a simulated 25,000 'patients' from each group, the proportion of wound closure over time was projected. Simulation results predicted a 55% wound closure rate at six months in the haemoglobin group, compared with 4% in the standard care group. Over a 12-month simulation period, a 43% overall reduction in wound burden was predicted. With the haemoglobin spray, 85% of wounds were expected to heal in 12 months, compared with 13% in the standard care group. Topical haemoglobin spray promises a more effective treatment for chronic venous leg ulcers than standard care alone in wounds that are non-healing or worsening. Further research is required to validate these predictions and to identify achievable outcomes in other chronic wound types.

Components and Quality Measures of DIME (Devitalized Tissue, Infection/Inflammation, Moisture Balance, and Edge Preparation) in Wound Care

ABSTRACT OBJECTIVES: To discuss how patient considerations and the initial wound environment can affect wound treatment and summarize the way in which the initial US Wound Registry measures capture aspects of the DIME (Debridement/devitalized tissue, Infection or inflammation, Moisture balance, and wound Edge preparation/wound depth) principles. DISCUSSION: The treatment of chronic wounds often involves extended hospital stays and long-term outpatient follow-up visits with costly advanced therapeutic interventions. As complex care is required for chronic wounds, treatment guidelines such as DIME have evolved to include consideration of patient-centered concerns and etiology, as well as features of wound bed preparation. The US healthcare system is in the midst of transitioning to a quality-based system. However, as wound care is not yet a recognized specialty, it is poorly represented in the current approved quality-based measures. CONCLUSION: This article helps to identify the practice guidelines that are not currently represented by quality metrics. PMID:27089149

The increasing numbers of cases of wound disease are now posing a big challenge in China. For more convenience of wound patients, wound management in community health care centers under the supervision of a specialist at general hospitals is an ideal solution. To ensure an accurate diagnosis in community health clinics, it is important that "the same language" for wound description, which may be composed of unified format description, including wound image, must be achieved. We developed a wound information management system that was built up by acquisition terminal, wound description, data bank, and related software. In this system, a 3G mobile phone was applied as acquisition terminal, which could be used to access to the data bank. This documentation system was thought to be an appropriate proposal for community wound care because of its objectivity, uniformity, and facilitation. It also provides possibility for epidemiological study in the future. © The Author(s) 2014.

Best practice wound care.

This article describes the barriers, changes and achievements related to implementing one element of a wound care programme being best practice care. With the absence of a coordinated approach to wound care, clinical practice within our Area Health Service (AHS) was diverse, inconsistent and sometimes outdated. This was costly and harmful, leading to overuse of unhelpful care, underuse of effective care and errors in execution. The major aim was to improve the outcomes and quality of life for patients with wound care problems within our community. A collaborative across ten sites/services developed, implemented and evaluated policies and guidelines based on evidence-based bundles of care. Key barriers were local resistance and lack of experience in implementing structural and cultural changes. This was addressed by appointing a wound care programme manager, commissioning of a strategic oversight committee and local wound care committees. The techniques of spread and adoption were used, with early adopters making changes observable and allowing local adaption of guidelines, where appropriate. Deployment and improvement results varied across the sites, ranging from activity but no changes in practice to modest improvement in practice. Evaluating implementation of the leg ulcer guideline as an exemplar, it was demonstrated that there was a statistically significant improvement in overall compliance from 26% to 84%. However, only 7·7% of patients received all interventions to which they were entitled. Compliance with the eight individual interventions of the bundle ranged from 26% to 84%. Generic performance was evaluated against the wound assessment, treatment and evaluation plan with an average compliance of 70%. Early results identified that 20% of wounds were healed within the target of 10 days. As more standardised process are implemented, clinical outcomes should continue to improve and costs decrease. © 2011 The Authors. © 2011 Blackwell Publishing Ltd and Medicalhelplines.com Inc.

Mesenchymal Stem Cells: A Multimodality Option for Wound Healing.

PubMed

Hanson, Summer E

2012-08-01

Although significant resources are invested in wound care and healing annually, chronic wounds remain a major medical problem as they often present a more difficult challenge than the underlying disease. Current treatment options include a multitude of dressing materials, topical agents including antibiotics, enzymatic debriders, and growth factors, mechanical debridement, and optimization of medical comorbidities. Even under optimal circumstances, the healing process leads to some form of fibrosis and scarring. Studies suggest that mesenchymal stem/stromal cells (MSCs) isolated from these diverse tissues possess similar biological characteristics, differentiation potential, and immunological properties. Enthusiasm about MSCs for use in reconstruction and regenerative medicine has been fueled by evidence that these cells possess the ability to participate in the tissue repair process through a variety of paracrine mechanisms affecting tissue regeneration and inflammation. Recent advances in stem cell immunobiology have led to increased interest in MSCs as a new therapeutic modality to address chronic wounds and other inflammatory pathology. A thorough understanding of the immunobiology of MSCs is necessary to realize the complement of pathological processes that could be affected by MSC-based therapy. The novel methods reviewed here are highly promising, with the collective goal of identifying new therapeutic approaches to wound healing that are broadly applicable to many chronic diseases, and can safely accelerate the transition of basic research findings into clinical advances in many areas of regenerative medicine and reconstructive surgery.

Honey-based dressings and wound care: an option for care in the United States.

Pieper, Barbara

2009-01-01

Honey-based wound dressings have been used worldwide since ancient times. A honey product received US Federal Drug Administration approval in 2007, making this dressing an option for wound care. Honey has been found to exert anti-inflammatory and antibacterial effects without antibiotic resistance, promote moist wound healing, and facilitate debridement. However, it may cause a stinging pain. As is true of any wound dressing, its use must be carefully selected and monitored. Continued research is needed to add to its evidence base. This article provides a summary of the current evidence base for the use of honey and a review of its therapeutic effects and discusses implications for WOC nursing practice.

Maggot Debridement Therapy in Disaster Medicine.

Stadler, Frank; Shaban, Ramon Z; Tatham, Peter

2016-02-01

When disaster strikes, the number of patients requiring treatment can be overwhelming. In low-income countries, resources to assist the injured in a timely fashion may be limited. As a consequence, necrosis and wound infection in disaster patients is common and frequently leads to adverse health outcomes such as amputations, chronic wounds, and loss of life. In such compromised health care environments, low-tech and cheap wound care options are required that are in ready supply, easy to use, and have multiple therapeutic benefits. Maggot debridement therapy (MDT) is one such wound care option and may prove to be an invaluable tool in the treatment of wounds post-disaster. This report provides an overview of the wound burden experienced in various types of disaster, followed by a discussion of current treatment approaches, and the role MDT may play in the treatment of complex wounds in challenging health care conditions. Maggot debridement therapy removes necrotic and devitalized tissue, controls wound infection, and stimulates wound healing. These properties suggest that medicinal maggots could assist health care professionals in the debridement of disaster wounds, to control or prevent infection, and to prepare the wound bed for reconstructive surgery. Maggot debridement therapy-assisted wound care would be led by health care workers rather than physicians, which would allow the latter to focus on reconstructive and other surgical interventions. Moreover, MDT could provide a larger window for time-critical interventions, such as fasciotomies to treat compartment syndrome and amputations in case of life-threatening wound infection. There are social, medical, and logistic hurdles to overcome before MDT can become widely available in disaster medical aid. Thus, research is needed to further demonstrate the utility of MDT in Disaster Medicine. There is also a need for reliable MDT logistics and supply chain networks. Integration with other disaster management activities will also be essential. In the aftermath of disasters, MDT could play an important role facilitating timely and efficient medical treatment and improving patient outcomes. Existing social, medical, and logistic barriers will need to be overcome for MDT to be mainstreamed in Disaster Medicine.

Bacteriophages could be used along with burn wound care products to enhance antimicrobial pressure during treatment. However, some of the components of the topical antimicrobials that are traditionally used for the prevention and treatment of burn wound infection might affect the activity of phages. Therefore, it is imperative to determine the counteraction of therapeutic phage preparations by burn wound care products before application in patients. Five phages, representatives of two morphological families (Myoviridae and Podoviridae) and active against 3 common bacterial burn wound pathogens (Acinetobacter baumannii, Pseudomonas aeruginosa and Staphylococcus aureus) were tested against 13 different products commonly used in the treatment of burn wounds. The inactivation of the phages was quite variable for different phages and different products. Majority of the anti-infective products affected phage activity negatively either immediately or in the course of time, although impact was not always significant. Products with high acidity had the most adverse effect on phages. Our findings demonstrate that during combined treatment the choice of phages and wound care products must be carefully defined in advance. PMID:28750102

A long period is generally required for ischemic ulcer to heal after revascularization. The strategy of postoperative wound care can affect wound healing. This study was conducted to investigate the degree to which aggressive wound care (AWC) by a team of multidisciplinary specialists actually shortens the time to wound healing and increases the rate of wound healing in limbs undergoing surgical bypass for ischemic tissue loss in a real clinical setting. A total of consecutive 126 patients undergoing infrainguinal bypass for tissue loss from April 2011 to March 2015 were reviewed. Prior to March 2013, standard wound care (SWC) including typical daily dressing change with disinfection and irrigation, occasional surgical debridement, and negative pressure wound therapy (when necessary) was performed by vascular surgeons. Thereafter, in addition to SWC, AWC including intense daily bedside surgical debridement under a sciatic nerve block by an anesthesiologist and active skin grafting by a dermatologist, if necessary, was performed. Wound healing and major amputation were defined as the end points. The 1-year outcomes of the 2 groups were calculated using the Kaplan-Meier method and compared, and the significant predictors of each outcome were determined by a Cox proportional hazards analysis. The wound healing of the AWC group was superior to that of the SWC group (AWC versus SWC, 1-year wound healing rate: 92% vs. 80%; mean wound healing time: 48 days vs. 82 days; P = 0.011), and no significant difference between the 2 regimens in the freedom from major amputation was observed. AWC, Rutherford 5, no wound infection, normal serum albumin, direct angiosome, and cilostazol use were significant predictors of wound healing, and female gender and no cilostazol use were significant predictors of major amputation by a multivariate analysis. Aggressive wound care by the team consisting of multidisciplinary specialists remarkably shortened the time to wound healing and increased the rate of wound healing within 1 year.

People with complex wounds are more likely to be elderly, living with multimorbidity and wound related symptoms. A variety of products are available for managing complex wounds and a range of healthcare professionals are involved in wound care, yet there is a lack of good evidence to guide practice and services. These factors create uncertainty for those who deliver and those who manage wound care. Formal priority setting for research and implementation topics is needed to more accurately target the gaps in treatment and services. We solicited practitioner and manager uncertainties in wound care and held a priority setting workshop to facilitate a collaborative approach to prioritising wound care-related uncertainties. We recruited healthcare professionals who regularly cared for patients with complex wounds, were wound care specialists or managed wound care services. Participants submitted up to five wound care uncertainties in consultation with their colleagues, via an on-line survey and attended a priority setting workshop. Submitted uncertainties were collated, sorted and categorised according professional group. On the day of the workshop, participants were divided into four groups depending on their profession. Uncertainties submitted by their professional group were viewed, discussed and amended, prior to the first of three individual voting rounds. Participants cast up to ten votes for the uncertainties they judged as being high priority. Continuing in the professional groups, the top 10 uncertainties from each group were displayed, and the process was repeated. Groups were then brought together for a plenary session in which the final priorities were individually scored on a scale of 0-10 by participants. Priorities were ranked and results presented. Nominal group technique was used for generating the final uncertainties, voting and discussions. Thirty-three participants attended the workshop comprising; 10 specialist nurses, 10 district nurses, seven podiatrists and six managers. Participants had been qualified for a mean of 20.7 years with a mean of 16.8 years of wound care experience. One hundred and thirty-nine uncertainties were submitted electronically and a further 20 were identified on the day of the workshop following lively, interactive group discussions. Twenty-five uncertainties from the total of 159 generated made it to the final prioritised list. These included six of the 20 new uncertainties. The uncertainties varied in focus, but could be broadly categorised into three themes: service delivery and organisation, patient centred care and treatment options. Specialist nurses were more likely to vote for service delivery and organisation topics, podiatrists for patient centred topics, district nurses for treatment options and operational leads for a broad range. This collaborative priority setting project is the first to engage front-line clinicians in prioritising research and implementation topics in wound care. We have shown that it is feasible to conduct topic prioritisation in a short time frame. This project has demonstrated that with careful planning and rigor, important questions that are raised in the course of clinicians' daily decision making can be translated into meaningful research and implementation initiatives that could make a difference to service delivery and patient care.

2008-04-01

The study goal was to evaluate the impact of the telemedicine consult on patients with chronic wounds. Thirty patients from long-term care skilled nursing facilities, referred to the ambulatory wound care program for wound assessment and preparation of management plans, were the subject of this prospective, randomized trial. To facilitate communication with a surgical wound care specialist, telemedicine feedback was provided prior to face-to-face consultation to 15 patients. The telemedicine consult included (1) wound assessment, (2) rationale for the suggested wound management with emphasis on wound risk projections, and (3) prevention and benefits of surgical intervention. This was communicated to the patient by the field wound care nurse. The telemedicine impact was measured by assessing the duration of the subsequent face-to-face consultation and patient satisfaction with further care decisions as well as by validation of a decisional conflict scale. The average duration of the face-to-face consultation was 50 +/- 12 minutes versus 35 +/- 6 (p < 0.01) minutes for patients subjected to the telemedicine feedback preceding the direct contact with the specialist. The telemedicine consult was found to be a useful aid in increasing the satisfaction rate from care decisions ultimately made during the direct consult (acceptance rate 93% vs. 47% in those subjected to treatment without the intermediate telemedicine consult, p < 0.01). The decisional conflict as a state of uncertainty about the course of action to take was reduced in patients subjected to telemedicine decision aid. The average Decisional Conflict Scale score was 14 +/- 1.73 in patients subjected to telemedicine feedback as opposed to 35 +/- 4.26 (p < 0.001) in no-telemedicine contact. The telemedicine consult preceding face-to-face evaluation improved patient satisfaction and understanding of their care as well as increased the perception of shared decision making regarding the wound care.

Wound care issues and the ability to establish intravenous (IV) access among injured or ill crew members are a source of concern for NASA flight surgeons. Indeed, the microgravity environment and the remote nature of the International Space Station (ISS) pose unique challenges in diagnosing and treating an injured astronaut. Therefore, it is necessary to identify and adapt the best evidence based terrestrial practices regarding wound care, hemostasis, and IV access for use on the ISS. Methods: A panel of consultants was convened to evaluate the adequacy of the current ISS in-flight medical system for diagnosis and treatment of wounds and establishing IV access by a nonclinician crew medical officer. Participants were acknowledged experts in terrestrial wound care and/or operational medicine. Prior to the meeting, each panelist was encouraged to participate in a pre-summit online forum. Results: Eight external experts participated in a face-to-face meeting held at NASA-Johnson Space Center. Recommendations were made to augment the space station pharmacopoeia, as well as current wound care diagnostic, therapeutic, and deorbit criteria protocols. Additionally, suggestions were offered regarding IV access techniques and devices for use in the microgravity environment. Discussion: The results of the expert panel provide an evidence-based approach to the diagnosis and care of wounds in an injured astronaut on aboard the ISS. The results of the panel underscored the need for further research in wound therapy and IV access devices.

Painful dressing changes for chronic wounds: assessment and management.

PubMed

Solowiej, Kazia; Upton, Dominic

Wound pain can arise from the wound itself, continuing wound treatment and anticipatory pain, which occurs in some patients as a consequence of negative experiences of care. Specifically, pain caused by the removal and application of dressings has been identified as a major contributor to wound pain, from both patient and health professional perspectives. This article reviews literature on the impact of pain at dressing change, and provides practical suggestions for assessment and management of pain during wound care.

Many months after the devastating earthquake in January 2010, wounds remain a major disease burden in Haiti. Since January 2010, through the efforts of corporations, nonprofit charitable organizations, and medical professionals, advanced wound care techniques, including negative-pressure wound therapy (NPWT), have been introduced into the wound care regimens of various hospitals in Haiti. In June 2010, the authors completed their second volunteer trip at a Haitian hospital specializing in orthopedic wounds. The medical team was composed of a plastic surgeon, orthopedic surgeon, anesthesiologist, medical assistant, scrub technician, and registered nurse (specializing in plastic surgery and orthopedics). The authors' team supplied NPWT devices, reticulated open-cell foam dressings, and canisters donated by Kinetic Concepts, Inc, San Antonio, Texas, for use at the hospital. This report describes the medical challenges in postearthquake Haiti (including limb salvage and infection), benefits of adjunctive use of NPWT/reticulated open-cell foam, and current wound care status in a Haitian orthopedic hospital. The future role of NPWT in Haiti and during mass catastrophe in a least-developed country is also discussed.

Honey, known for centuries as a topical treatment for a wide range of wounds, has recently known a revival in modern wound care. The objective of this systematic review is to evaluate the available evidence and the role of honey in contemporary wound care. The search strategy was developed in the databases PubMed and ISI Web of Science. Fifty-five studies of any design, evaluating the use of honey in human burns, ulcers and other wounds, written in English, French, German or Dutch were eligible for inclusion. In all three wound categories honey seems to be a dressing with wound healing stimulating properties. In burns there is also evidence for its antibacterial capacity. In general, honey is also been mentioned to have deodorizing, debridement, anti-inflammatory and wound pain reducing properties, although the evidence for these properties is rather limited. Many of the included studies have methodological problems, and the quality of certain studies is low, making it difficult to formulate conclusive guidelines. This review reveals several gaps in the research of honey in modern wound care, and recommendations are suggested for future research. Copyright © 2013 Elsevier Ltd and ISBI. All rights reserved.

The need for improved wound care is receiving considerable attention in the Islamic Republic of Iran. Beginning in 2003, maggot therapy (MT) became part of Iran's effort to advance its wound care technology. The first cohort of patients treated with MT was analysed to evaluate the use of this treatment. Patients treated with MT at three hospitals in Tehran were analysed retrospectively. Primary outcomes were time to wound debridement and time to wound healing. Factors potentially influencing primary outcomes were also recorded, including demographic factors (such as age, race, gender), wound characteristics, underlying medical illnesses, and treatment attitudes. We analysed 28 patients with 29 wounds. Most (55%) of the wounds were ischaemic, neuropathic or mixed-pathology foot ulcers in patients with diabetes. Half were considered unsalvageable. All were completely debrided and subsequently healed with MT, without amputation, grafts, or advanced interventions. Osteomyelitis was present in all cases before MT, but appeared to have been eradicated, without recurrence during at least three years' follow-up. The most common adverse events were malodour, with wound pain reported in two patients. All patients and therapists were pleased with their overall experience. Maggot therapy can provide advanced wound care even in resource-limited areas. Maggot therapy was very acceptable to the patients and their therapists.

Randomized controlled trials in wound care generalize poorly because they exclude patients with significant comorbid conditions. Research using real-world wound care patients is hindered by lack of validated methods to stratify patients according to severity of underlying illnesses. We developed a comprehensive stratification system for patients with wounds that predicts healing likelihood. Complete medical record data on 50,967 wounds from the United States Wound Registry were assigned a clear outcome (healed, amputated, etc.). Factors known to be associated with healing were evaluated using logistic regression models. Significant variables (p < 0.05) were determined and subsequently tested on a holdout sample of data. A different model predicted healing for each wound type. Some variables predicted significantly in nearly all models: wound size, wound age, number of wounds, evidence of bioburden, tissue type exposed (Wagner grade or stage), being nonambulatory, and requiring hospitalization during the course of care. Variables significant in some models included renal failure, renal transplant, malnutrition, autoimmune disease, and cardiovascular disease. All models validated well when applied to the holdout sample. The "Wound Healing Index" can validly predict likelihood of wound healing among real-world patients and can facilitate comparative effectiveness research to identify patients needing advanced therapeutics. © 2013 by the Wound Healing Society.

Open-to-Air Is a Viable Option for Initial Wound Care in Necrotizing Soft Tissue Infection that Allows Early Detection of Recurrence without Need for Painful Dressing Changes or Return to Operating Room.

The standard treatment of necrotizing soft tissue infection (NSTI) includes extensive surgical debridement. Care of these debridements is challenging because of the size of the wound and associated pain. A potential solution is to leave the wounds open-to-air in the period after the initial debridement, allowing for regular inspection at bedside while reducing pain associated with frequent dressing changes. We evaluated the feasibility of this approach from a pain control standpoint. An audit of wound care modalities used on adult patients with NSTI admitted to a regional burn center between January 2009 and May 2014 was performed. Patients with at least one operation were included. Those opting for palliative care were excluded. Wound care was divided into four categories: open-to-air (OTA), negative-pressure wound therapy (NPWT), packing, and ointment. Wound care, pain score, pain medication use, and number of operations were collected for the first seven days after initial debridement. Pain management was assessed by pain scores. Analgesic use was measured and compared using conversion to morphine milligram equivalents (MME). Ninety-six patients were included; 67% were men with average age of 50 years, resulting in a total of 672 days of wound care evaluated: 69 days of OTA, 127 days of NPWT, 200 days of packing, and 126 days of ointment (150 days were undocumented). Average daily pain score from all wound care modalities was 2.00. Negative pressure wound therapy had the highest reported daily pain score (2.18, p = 0.034), whereas OTA had the lowest pain score (1.63, p < 0.05). Mortality was lower in the OTA cohort but was not statistically significant; there were no other differences in long-term outcome. Leaving wounds OTA is a safe and viable option in the immediate post-debridement period of NSTI to reduce pain, while permitting frequent re-evaluation for quick recognition of disease progression and repeat operative debridement if necessary.

Maida, Vincent

2013-03-01

To emphasize that the management of wounds represents a significant component within the overall supportive and palliative care of patients with advanced illness. It is also intended to clarify the linguistics that are commonly used around patients with wounds. New paradigms for wound management, wound outcomes, and goal setting have been defined and graphically depicted. Recent studies show that wounds may be used as prognostic factors for patients with advanced illness. Data from recent studies also demonstrate that marginal levels of wound healing are possible for all wound classes affecting patients with advanced illness. When indicated, time-limited trials of wound healing strategies should be facilitated by the Wound Bed Preparation Paradigm. Wound palliation may be guided through the use of the Toronto Symptom Assessment System for Wounds (TSAS-W). Wound management must continue to evolve as a tenet within the overall supportive and palliative care of patients with advanced illness.

To provide information about the current state of educating nurses about wound care and pressure injuries with recommendations for the future. This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and nurses with an interest in skin and wound care. After participating in this educational activity, the participant should be better able to:1. Discuss the importance of pressure injury education and wound care for nurses and identify the current state of nursing education on the subject. 2. Identify strategies that can be used to put improved wound care and pressure injury education into practice. Wound care nursing requires knowledge and skill to operationalize clinical guidelines. Recent surveys and studies have revealed gaps in nurses' knowledge of wound care and pressure injuries and their desire for more education, both in their undergraduate programs and throughout their careers. Data from baccalaureate programs in the United States can pinpoint areas for improvement in nursing curriculum content. Lifelong learning about wound care and pressure injuries starts with undergraduate nursing education but continues through the novice-to-expert Benner categories that are facilitated by continuing professional development. This article introduces a pressure injury competency skills checklist and educational strategies based on Adult Learning principles to support knowledge acquisition (in school) and translation (into clinical settings). The responsibility for lifelong learning is part of every nurse's professional practice.

The use of medical grade honey in clinical practice.

Dunwoody, Gillian; Acton, Claire

In the current healthcare environment, clinicians are increasingly under pressure to use wound care products that are cost-effective. This includes products that can be used in a variety of wounds to achieve different outcomes, depending on the wound-bed requirements. Medical grade honey has emerged as a product that can achieve a variety of outcomes within the wound and is safe and easy to use. This article reviews the use of a medical grade honey (Medihoney) in various clinical applications, with a view to placement on the wound care formulary in both primary and secondary care. It provides an in-depth account of case studies featured in a poster presentation at the 2008 European Wound Management Association meeting in Lisbon, Portugal.

The management of chronic wounds has emerged as a major health care challenge during the 21st century consuming, significant portions of health care budgets. Chronic wounds such as diabetic foot ulcers, leg ulcers, and pressure sores have a significant negative impact on the quality of life of affected individuals. Covering wounds with suitable dressings facilitates the healing process and is common practice in wound management plans. However, standard dressings do not provide insights into the status of the wound underneath. Parameters such as moisture, pressure, temperature and pH inside the dressings are indicative of the healing rate, infection, and wound healing phase. But owing to the lack of information available from within the dressings, these are often changed to inspect the wound, disturbing the normal healing process of wounds in addition to causing pain to the patient. Sensors embedded in the dressing would provide clinicians and nurses with important information that would aid in wound care decision making, improve patient comfort, and reduce the frequency of dressing changes. The potential benefits of this enabling technology would be seen in terms of a reduction in hospitalization time and health care cost. Modern sensing technology along with wireless radio frequency communication technology is poised to make significant advances in wound management. This review discusses issues related to the design and implementation of sensor technology and telemetry systems both incorporated in wound dressings to devise an automated wound monitoring technology, and also surveys the literature available on current sensor and wireless telemetry systems.

Zarchi, Kian; Haugaard, Vibeke B; Dufour, Deirdre N; Jemec, Gregor B E

2015-03-01

Telemedicine is widely considered as an efficient approach to manage the growing problem of chronic wounds. However, to date, there is no convincing evidence to support the clinical efficacy of telemedicine in wound management. In this prospective cluster controlled study, we tested the hypothesis that advice on wound management provided by a team of wound-care specialists through telemedicine would significantly improve the likelihood of wound healing compared with the best available conventional practice. A total of 90 chronic wound patients in home care met all study criteria and were included: 50 in the telemedicine group and 40 in the conventional group. Patients with pressure ulcers, surgical wounds, and cancer wounds were excluded. During the 1-year follow-up, complete wound healing was achieved in 35 patients (70%) in the telemedicine group compared with 18 patients (45%) in the conventional group. After adjusting for important covariates, offering advice on wound management through telemedicine was associated with significantly increased healing compared with the best available conventional practice (telemedicine vs. conventional practice: adjusted hazard ratio 2.19; 95% confidence interval: 1.15-4.17; P=0.017). This study strongly supports the use of telemedicine to connect home-care nurses to a team of wound experts in order to improve the management of chronic wounds.

Holistic approach as the philosophical orientation to care underpins the fundamental wholeness of human being and emphasizes the importance of balance within the person and between the person and his/her environment. It includes elements of the physiological, sociological, economic, psychological and spiritual dimensions, and thus providesan opportunity to assess the patient as a whole and in relation to his/ her living context. Such an integrated approach is part of the basic knowledge and skills of general practitioners/family doctors and makes them equal members of a multidisciplinary team in chronic wound patient care. In this case report on a patient with mixed leg ulcer, we will try to bring closer holistic approach in care for this kind of patients in daily practice of general practitioners/family doctors.

The economic benefits of negative pressure wound therapy in community-based wound care in the NHS.

PubMed

Dowsett, Caroline; Davis, Lynn; Henderson, Valerie; Searle, Richard

2012-10-01

The human and economic costs of wounds are of major concern within today's National Health Service. Advances in wound care technology have been shown to be beneficial both in healing and in relation to patient quality of life. Negative pressure has often been associated with high-cost care and restricted to use in the secondary care setting. There is growing use of negative pressure within the community, and this has the potential to benefit the patient and the service by providing quality care in the patient's home setting. Three community sites were chosen to monitor their use of negative pressure wound therapy (NPWT) over a period of 2 years, and this paper presents some of the key findings of this work. The data generated has been used to help target resources and prevent misuse of therapy. Cost per patient episode has been calculated, and this can be compared to similar costs in secondary care, showing significant savings if patients are discharged earlier from secondary care. There is also an increased demand for more patients with complex wounds to be cared for in the community, and in the future, it is likely that community initiated NPWT may become more common. Early analysis of the data showed that the average cost of dressing complex wounds would be significantly less than using traditional dressings, where increased nursing visits could increase costs. There is a compelling argument for more negative pressure to be used and initiated in the community, based not only on improved quality of life for patients but also on the economic benefits of the therapy. © 2012 The Authors.

Medicare skilled nursing facility (SNF) residents with chronic wounds require more resources and have relatively high healthcare expenditures compared to Medicare patients without wounds. A retrospective cohort study was conducted using 2006 Medicare Chronic Condition Warehouse claims data for SNF, inpatient, outpatient hospital, and physician supplier settings along with 2006 Long-Term Care Minimum Data Set (MDS) information to compare Medicare expenditures between two groups of SNF residents with a diagnosis of pressure, venous, ischemic, or diabetic ulcers whose wounds healed during the 10-month study period. The study group (n = 372) was managed using a structured, comprehensive wound management protocol provided by an external wound management team. The matched comparison group consisted of 311 SNF residents who did not receive care from the wound management team. Regression analyses indicate that after controlling for resident comorbidities and wound severity, study group residents experienced lower rates of wound-related hospitalization per day (0.08% versus 0.21%, P < 0.01) and shorter wound episodes (94 days versus 115 days, P < 0.01) than comparison group patients. Total Medicare costs were $21,449.64 for the study group and $40,678.83 for the comparison group (P < 0.01) or $229.07 versus $354.26 (P < 0.01) per resident episode day. Additional studies including wounds that do not heal are warranted. Increasing the number of SNF residents receiving the care described in this study could lead to significant Medicare cost savings. Incorporating wound clinical outcomes into a pay-for-performance measures for SNFs could increase broader SNF adoption of comprehensive wound care programs to treat chronic wounds.

To investigate the amount, type and accuracy of citations use in support of product related claims from advertisements of wound care products. Although articles submitted to most medical journals are subjected to peer review, such scrutiny is often not required for the content of advertisements. A contents survey of advertisements from two wound care journals (Journal of Wound Care and Ostomy Wound Management) from 2002-2003 and the British Medical Journal, 2002-2003. Data collected from advertisements included identification of product related claims made and any corresponding citations. Where journal articles were cited to support claims, the articles were obtained. Where data on file were cited, this material was requested. In each case the accuracy of claims in relation to the content of the supporting citation was assessed. The use of citations to support product related claims was infrequent in advertisements from wound care journals, where 35% of advertisements containing a product related claim also contained at least one citation, compared with 63% of advertisements from the British Medical Journal. Of citations that were supplied, journal articles were less common in the wound journals (40% vs. 73% in the British Medical Journal) and data on file more common (38% vs. 6% in the British Medical Journal). Where journal articles were obtained, 56% of claims in the wound care journals advertisements were not supported by the cited article, compared with 12% of claims in the British Medical Journal. The wound journals advertised predominantly medical devices. The use and accuracy of referencing in advertisements from wound care journals was poor. Nurses have increasing responsibilities for the prescribing of both drugs and devices, which must be accompanied by the ability to interpret marketing materials and research evidence critically. Nurse educators must ensure that nurse education generally and nurse prescriber training particularly, builds skills of information retrieval and critical appraisal.

Anderson, John A. E.; Evans, Robyn; Woo, Kevin; Beland, Benjamin; Sasseville, Denis; Moreau, Linda

2017-01-01

Background Current wound assessment practices are lacking on several measures. For example, the most common method for measuring wound size is using a ruler, which has been demonstrated to be crude and inaccurate. An increase in periwound temperature is a classic sign of infection but skin temperature is not always measured during wound assessments. To address this, we have developed a smartphone application that enables non-contact wound surface area and temperature measurements. Here we evaluate the inter-rater reliability and accuracy of this novel point-of-care wound assessment tool. Methods and findings The wounds of 87 patients were measured using the Swift Wound app and a ruler. The skin surface temperature of 37 patients was also measured using an infrared FLIR™ camera integrated with the Swift Wound app and using the clinically accepted reference thermometer Exergen DermaTemp 1001. Accuracy measurements were determined by assessing differences in surface area measurements of 15 plastic wounds between a digital planimeter of known accuracy and the Swift Wound app. To evaluate the impact of training on the reproducibility of the Swift Wound app measurements, three novice raters with no wound care training, measured the length, width and area of 12 plastic model wounds using the app. High inter-rater reliabilities (ICC = 0.97–1.00) and high accuracies were obtained using the Swift Wound app across raters of different levels of training in wound care. The ruler method also yielded reliable wound measurements (ICC = 0.92–0.97), albeit lower than that of the Swift Wound app. Furthermore, there was no statistical difference between the temperature differences measured using the infrared camera and the clinically tested reference thermometer. Conclusions The Swift Wound app provides highly reliable and accurate wound measurements. The FLIR™ infrared camera integrated into the Swift Wound app provides skin temperature readings equivalent to the clinically tested reference thermometer. Thus, the Swift Wound app has the advantage of being a non-contact, easy-to-use wound measurement tool that allows clinicians to image, measure, and track wound size and temperature from one visit to the next. In addition, this tool may also be used by patients and their caregivers for home monitoring. PMID:28817649

Treatment Options to Manage Wound Biofilm

PubMed Central

Jones, Curtis E.; Kennedy, John P.

2012-01-01

Background Bioburden is an accepted barrier to chronic wound healing. Defining the significance, phenotype, clinical classification, and treatment guidelines has been historically lacking of evidence and based on paradigms that do not represent the scientific or clinical reality. The Problem Chronic wound bioburden is typically abundant, polymicrobial, and extremely diverse. These microbes naturally adopt biofilm phenotypes, which are quite often viable but not culturable, thereby going undetected. The failures of culture-based detection have led to abandonment of routine bioburden evaluation and aggressive treatment or, worse, to assume bioburden is not a significant barrier. Predictably, treatment regimens to address biofilm phenotypes lagged behind our diagnostic tools and understanding. Basic/Clinical Science Advances Microbial DNA-based diagnostic tools and treatment regimens have emerged, which provide and leverage objective information, resulting in a dramatic impact on outcomes. Relevance to Clinical Care Modern medicine demands decisions based on objective evidence. The diagnostic and treatment protocols reviewed herein empower clinicians to practice modern medicine with regard to bioburden, with DNA level certainty. Conclusion Bioburden is a significant barrier to healing for all chronic wounds. Molecular diagnostics provide the first objective means of assessing wound bioburden. The accuracy and comprehensive data from such diagnostic methodologies provide clinicians with the ability to employ patient-specific treatment options, targeted to each patient's microbial wound census. Based on current outcomes data, the most effective therapeutic options are topical (TPL) antibiofilm agents (ABF) combined with TPL antibiotics (ABX). In specific patients, systemic ABX and selective biocides are also appropriate, but not exclusive of ABF combined with TPL ABX. PMID:24527291

The effects of TeleWound management on use of service and financial outcomes.

PubMed

Rees, Riley S; Bashshur, Noura

2007-12-01

This study investigated the effects of a TeleWound program on the use of service and financial outcomes among homebound patients with chronic wounds. The TeleWound program consisted of a Web-based transmission of digital photographs together with a clinical protocol. It enabled homebound patients with chronic pressure ulcers to be monitored remotely by a plastic surgeon. Chronic wounds are highly prevalent among chronically ill patients in the United States (U.S.). About 5 million chronically ill patients in the U.S. have chronic wounds, and the aggregate cost of their care exceeds $20 billion annually. Although 25% of home care referrals in the U.S. are for wounds, less than 0.2% of the registered nurses in the U.S. are wound care certified. This implies that the majority of patients with chronic wounds may not be receiving optimal care in their home environments. We hypothesized that TeleWound management would reduce visits to the emergency department (ED), hospitalization, length of stay, and visit acuity. Hence, it would improve financial performance for the hospital. A quasi-experimental design was used. A sample of 19 patients receiving this intervention was observed prospectively for 2 years. This was matched to a historical control group of an additional 19 patients from hospital records. Findings from the study revealed that TeleWound patients had fewer ED visits, fewer hospitalizations, and shorter length of stay, as compared to the control group. Overall, they encumbered lower cost. The results of this clinical study are striking and provide strong encouragement that a single provider can affect positive clinical and financial outcomes using a telemedicine wound care program. TeleWound was found to be a credible modality to manage pressure ulcers at lower cost and possibly better health outcomes. The next step in this process is to integrate the model into daily practice at bellwether medical centers to determine programmatic effectiveness in larger clinical arenas.

To test the hypothesis that fluconazole plus standard care is superior to the standard care for diabetic foot wounds infected with deep-seated fungal infections. We carried out a randomized, controlled, open-label, parallel-arm study in 75 patients with both fungal and bacterial infections in deep tissues of diabetic foot wounds. Thirty-seven patients (control group) were given standard care (surgical debridement + culture-specific antibiotics + offloading + glycaemic control) and 38 patients (treatment group) were given fluconazole 150 mg daily plus standard care. Wound surface area was measured every 2 weeks until the endpoints (complete epithelialization or skin grafting) were met. By week 4, the mean wound surface area reduced to 27.3 from 111.5 cm(2) in the treatment group, as opposed to 67.1 from 87.3 cm(2) in the control group. Subsequently, the mean wound surface areas were remarkably smaller in the treatment group compared with the control group, and statistically significant differences (P ≤ 0.05) in mean wound surface area were observed between the treatment group and the control group at week 6. However, no statistically significant (P ≤ 0.47) difference in complete healing was observed between the treatment group and the control group, 20 vs. 24. The mean wound healing time for the treatment group was 7.3 weeks, whereas for the control group it was 11.3 weeks (P ≤ 0.022). Similarly, the probability of wound healing in the treatment group was 50 vs. 20% in the control group at week 10. Fluconazole plus standard care was superior to standard care alone in accelerating wound reduction among patients with diabetes with deep-seated fungal infections in diabetic foot wounds. Those in the treatment group who did heal, healed more quickly (P ≤ 0.022), but overall healing was not different. © 2012 The Authors. Diabetic Medicine © 2012 Diabetes UK.

Diabetic foot ulcers are a feared complication of diabetes. Care delivered via telemedicine is suggested to be a more integrated care pathway to manage diabetic foot ulcers than traditionally delivered healthcare. Our aim was to explore patients' experiences with telemedicine follow-up care as compared to traditional care. Interpretive description was used as an analysis strategy. Data were collected using individual semi-structured interviews in the context of a larger ongoing clustered randomized controlled trial. Twenty-four patients (13 in the intervention group; 11 in the control group), aged 38-88 years were purposively recruited from the RCT in order to obtain a diverse sample in terms of group composition (intervention vs. control), age, gender, marital status, setting, and comorbidities present. The control group received traditional care. Three themes emerged from the interpretive analysis: competence of healthcare professionals, continuity of care, and easy access. This was independed of types of follow-up that had limited impact on the patients' follow-up experiences. Competence of healthcare professionals and continuity of care were crucial, because they can either enhance or jeopardize wound care. If these two latter factors were absent, patients would lose confidence in the wound care process. If this happened, patients pointed out that the expert knowledge of a specialist clinic was essential to receive good care. When telemedicine functioned optimally, telemedicine was an advantage in the treatment, because the images quickly captured changes in the wound healing that immediately could be corrected. Easy access is important for patients, but the importance of accessibility appears to be primary when the other two factors were present. The best wound care pathway for patients with diabetes foot ulcers is depended on a combination of competence and professional skills in wound management, and continuity of care. If telemedicine is functioning as intended, it can be an important additional tool. Copyright © 2016. Published by Elsevier Ireland Ltd.

The objective of this study was to compare the effect of virtual reality to passive distraction and standard care on burn treatment pain in adolescents.This single-blinded, randomized controlled study enrolled 30 adolescents who were 10 to 17 years of age from the burn clinic of a large children's hospital. After providing informed consent/assent, these participants were randomly assigned to one of three groups during wound care: standard care, passive distraction watching a movie, or virtual reality (VR) using a tripod-arm device rather than an immersive helmet. Before wound care, participants completed the Spielberger's State-Trait Anxiety Inventory for Children and Pre-Procedure Questionnaire while blinded to group assignment. A total of 28 participants completed the study and rated treatment pain after wound care by using the Adolescent Pediatric Pain Tool and completed a Post-Procedure Questionnaire. The VR group reported less pain during wound care than either the passive distraction or standard care group as determined by multivariable linear regression adjusted for age, sex, preprocedure pain, state anxiety, opiate use, and treatment length. The VR group was the only group to have an estimated decrease in pain perception from baseline preprocedure pain to procedural pain reported. Adolescents pretreated with opiate analgesics and female adolescents reported more pain during wound care.This between-subjects clinical study provides further support for VR, even without requiring wearing of an immersive helmet, in lessening burn wound care pain in adolescents. Passive distraction by watching a movie may be less effective in reducing treatment pain. Additional between-subjects randomized controlled trials with larger samples of children and during other healthcare treatments may further support VR's effectiveness in pediatric procedural pain management.

To perform, from an insurance perspective, a cost analysis of one of the outpatient community wound care clinics in the Netherlands, the Knowledge Centre in Wound Care (KCWC) at Venray. This study involved a cost analysis based on an observational cohort study with a one-year pre-admission and a one-year post-admission comparison of costs. Patients were included when they first consulted the outpatient wound care clinic. Participants were all insured by the same health insurance company, Coöperatie Volksgezondheidszorg (VGZ). A standard six-step procedure for performing cost studies was used to calculate the costs. Given the skewed cost data, non-parametric bootstrapping was used to test for statistical differences. There were 172 patients included in this study. The difference in costs related to wound care between the year before and the year after initial admission to the wound clinic amounted to an average reduction of €2621 (£1873) per patient in the base case analysis. The categories 'general practitioner', 'hospital care', 'mental health care' and 'transport' scored lower, indicating lower costs, in the year after admission to the wound clinic. In this study, only the reimbursement data of patients of one health insurance company, and specifically only those made under the 2006 Dutch Health Insurance Act, were available. Because of the observational design, definitive conclusions cannot be made regarding a demonstrated reduction of costs in the year post admission. Nevertheless, this study is a first attempt of a cost analysis of an equipped outpatient wound clinic as an innovative way of responding to the increasing number of chronic wounds in the Netherlands. The calculations show that savings in wound care are possible. A possible conflict of interest should be mentioned. First author AALM Rondas, PhD student at Maastricht University, is working at the KCWC wound clinic at Venray in the Netherlands as a physician. However, the research data were provided externally by Coöperatie Volksgezondheidszorg (VGZ) and checked by the academic co-authors, none of whom have a conflict of interest. The authors have no financial or commercial interest to declare.

Importance of Scar Prevention and Treatment-An Approach From Wound Care Principles.

The increased number of cosmetic surgical and nonsurgical procedures has led to a greater demand to achieve aesthetically acceptable scars. Silicone gel (SG) dressings were evaluated in these cases following the principles of wound care and also minimizing abnormal scar formation. A newly developed solution in wound care in the form of a SG has proven to be a highly effective treatment for a series of 4 clinically challenging cases presented in this article: postprocedure healing after a laser treatment, nonhealing scalp wounds, chronic relapsing xerotic eczematous cheilitis, and the treatment of scars caused by third degree burns. A standard SG was applied to improve the scar outcome of severe burns of a young child. Silicone gels offer excellent clinical results in these 4 cases. In terms of wound care and scar management, they provide a user friendly, convenient application form and increase patient comfort and compliance. To pursue these results, further studies need to be conducted but as of now, there is strong suggestive evidence that SGs indicate beneficial properties for wound care management and scar prevention.

Peroxidases have been implicated in the responses of plants to physiological stress and to pathogens. Wound-induced peroxidase of horseradish (Armoracia rusticana) was studied. Total peroxidase activity was increased by wounding in cell wall fractions extracted from roots, stems and leaves of horseradish. On the other hand, wounding decreased the peroxidase activity in the soluble fraction from roots. The enzyme activities of the basic isozymes were induced by wounding in horseradish leaves based on data obtained by fractionation of crude enzyme in isoelectric focusing gel electrophoresis followed by activity staining. We have previously isolated genomic clones for four peroxidase genes, namely, prxC1a, prxC1b, prxC2 and prxC3. Northern blot analysis using gene-specific probes showed that mRNA of prxC2, which encodes a basic isozyme, accumulated by wounding, while the mRNAs for other peroxidase genes were not induced. Tobacco (Nicotiana tabacum) plants were transformed with four chimeric gene constructs, each consisting of a promoter from one of the peroxidase genes and the β-glucuronidase (GUS) structural gene. High level GUS activity induced in response to wounding was observed in tobacco plants containing the prxC2-GUS construct.

Background. Ixora coccinea L. (Rubiaceae) has been documented for traditional use in hypertension, menstrual irregularities, sprain, chronic ulcer, and skin diseases. In the present study, I. coccinea was subjected to in vitro and in vivo wound healing investigation. Methods. Petroleum ether, chloroform, methanol, and water sequential I. coccinea leaves extracts were evaluated for in vitro antioxidant, antimicrobial, and fibroblast proliferation activities. The promising I. coccinea methanol extract (IxME) was screened for in vivo wound healing activity in Wistar rat using circular excision model. Wound contraction measurement, hydroxyproline quantification, and western blot for collagen type III (COL3A1), basic fibroblast growth factor (bFGF), and Smad-2, -3, -4, and -7 was performed with 7-day postoperative wound granulation tissue. Gentamicin sulfate (0.01% w/w) hydrogel was used as reference standard. Results. IxME showed the potent antimicrobial, antioxidant activities, with significant fibroblast proliferation inducing activity, as compared to all other extracts. In vivo study confirmed the wound healing accelerating potential of IxME, as evidenced by faster wound contraction, higher hydroxyproline content, and improved histopathology of granulation tissue. Western blot analysis revealed that the topical application of I. coccinea methanol extract stimulates the fibroblast growth factor and Smad mediated collagen production in wound tissue.

Our purpose was to compare healing characteristics of diabetic foot ulcers treated with dehydrated human amniotic membrane allografts (EpiFix®, MiMedx, Kennesaw, GA) versus standard of care. An IRB-approved, prospective, randomised, single-centre clinical trial was performed. Included were patients with a diabetic foot ulcer of at least 4-week duration without infection having adequate arterial perfusion. Patients were randomised to receive standard care alone or standard care with the addition of EpiFix. Wound size reduction and rates of complete healing after 4 and 6 weeks were evaluated. In the standard care group (n = 12) and the EpiFix group (n = 13) wounds reduced in size by a mean of 32.0% ± 47.3% versus 97.1% ± 7.0% (P < 0.001) after 4 weeks, whereas at 6 weeks wounds were reduced by -1.8% ± 70.3% versus 98.4% ± 5.8% (P < 0.001), standard care versus EpiFix, respectively. After 4 and 6 weeks of treatment the overall healing rate with application of EpiFix was shown to be 77% and 92%, respectively, whereas standard care healed 0% and 8% of the wounds (P < 0.001), respectively. Patients treated with EpiFix achieved superior healing rates over standard treatment alone. These results show that using EpiFix in addition to standard care is efficacious for wound healing. ©2013 The Authors.

A common language and lexicon provide the easiest means of mutual understanding. Inconsistency in terminology makes effective information exchange difficult. Previous studies identified the need to determine standard, accepted definitions for the vocabulary frequently used in wound care. The objective of this study was to establish content validation for these terms and develop an evidence-based glossary for this specialty. Members of the Association for the Advancement of Wound Care Quality of Care Task Force reviewed literature to determine glossary content generation and the associated literature-based definitions. Thirty-nine wound care professionals from wound care stakeholder professional organizations in the United States and Canada participated in the content validation process. Participants were asked to quantify the degree of validity using a 367-item, 4-point Likert-type scale. On a scale of 1 to 4, the mean score of the entire instrument was 3.84. The instrument's overall scale content validity index was 0.96. Terms with an item content validity index of less than 0.70 were removed from the glossary, leaving 365 items with established content validity. Qualitative data analysis revealed themes suggesting that enhanced communication between providers improves patient outcomes. The need for ongoing updates of the glossary was also identified. The wound care glossary in its finalized form proved valid. An evidence-based glossary bridges the chasm of miscommunication and nonstandardization so that wound care, as an emerging specialized medical science field, can move forward to optimize both process and clinical outcomes.

[Nursing Care Experiences of Periwound Moisture-Associated Dermatitis After Simultaneous Pancreas-Kidney Transplantation].

PubMed

Yeh, Pei-Ying; Chen, Hsiao-Ping; Wu, Jing-Yi

2018-04-01

Simultaneous pancreas-kidney (SPK) transplantation is the primary surgical treatment for type I diabetes mellitus with end-stage renal disease. However, this transplant surgery has a high-risk of surgical complications, including duodenal anastomotic leakage, which may lead to pancreas transplantation failure if the leakage worsens. This case report describes a patient who suffered from duodenal anastomotic leakage after SPK transplantation. The digestive enzymes eroded the wound and skin around the wound, resulting in periwound moisture-associated dermatitis. During the period of nursing care, the wound-care intervention was determined by interdisciplinary cooperation. In our case report, the periwound moisture-associated dermatitis healed completely under inter-hospital care. In clinical nursing practice, periwound moisture-associated dermatitis should be cared in combination with macerated wounds. We suggest the following: (1) control the moisture source; (2) use advanced dressings as the primary dressing with sterile gauze as a secondary dressing and silver antimicrobial dressings for infected wounds; (3) consider using negative pressure wound therapy for complicated chronic wounds; and (4) use a pH-neutral skin cleanser with non-woven gauze to clean the periwound skin and keep the skin clean and dry. Finally, we suggest isolating and protecting the skin with No Sting Barrier Film and a hydrocolloid dressing. We hope this nursing care experiences serves as a reference for the nursing care of periwound moisture-associated dermatitis resulting from duodenal anastomotic leakage during / after SPK transplantation.

In September 2014, wound clinic A reported a cluster of group A Streptococcus (GAS) infections to public health authorities. Although clinic providers were individually licensed, the clinic, affiliated with hospital A, was not licensed or subject to regulation. We investigated to identify cases, determine risk factors, and implement control measures. A case was defined as GAS isolation from a wound or blood specimen during March 28-November 19, 2014, from a patient treated at wound clinic A or by a wound clinic A provider within the previous 7 days. All wound clinic A staff were screened for GAS carriage. Wound care procedures were assessed for adherence to infection control principles and possible GAS transmission routes. We identified 16 patients with 19 unique infections: 9 (56%) patients required hospitalization, and 7 (44%) required surgical debridement procedures. One patient died. Six (37%) patients received negative pressure wound therapy at GAS onset. Staff self-screening found no GAS carriers. Breaches in infection control and poor wound care practices were widespread. This GAS outbreak was associated with a wound care clinic not subject to state or federal regulation. Lapses in infection control practices and inadequate oversight contributed to the outbreak.

The clinical significance of timely re-epithelialization is obvious in burn care, since delayed wound closure is enhancing the risk of wound site infection and extensive scarring. Topical treatments that accelerate wound healing are urgently needed to reduce these sequelae. Evidence from preliminary studies suggests that betulin can accelerate the healing of different types of wounds, including second degree burns and split-thickness skin graft wounds. The goal of this combined study program consisting of two randomized phase III clinical trials in parallel is to evaluate whether a topical betulin gel (TBG) is accelerating re-epithelialization of split-thickness skin graft (STSG) donor site wounds compared to standard of care. Two parallel blindly evaluated, randomised, controlled, multicentre phase III clinical trials were performed in adults undergoing STSG surgery (EudraCT nos. 2012-003390-26 and 2012-000777-23). Donor site wounds were split into two equal halves and randomized 1:1 to standard of care (a non-adhesive moist wound dressing) or standard of care plus TBG consisting of 10% birch bark extract and 90% sunflower oil (Episalvan, Birken AG, Niefern-Oeschelbronn, Germany). The primary efficacy assessment was the intra-individual difference in time to wound closure assessed from digital photographs by three blinded experts. A total of 219 patients were included and treated in the two trials. Wounds closed faster with TBG than without it (15.3 vs. 16.5 days; mean intra-individual difference=-1.1 days [95% CI, -1.5 to -0.7]; p<0.0001). This agreed with unblinded direct clinical assessment (difference=-2.1 days [95% CI, -2.7 to -1.5]; p<0.0001). Adverse events possibly related to treatment were mild or moderate and mostly at the application site. TBG accelerates re-epithelialization of partial thickness wounds compared to the current standard of care, providing a well-tolerated contribution to burn care in practice.

Comparative effectiveness of the SNaP™ Wound Care System.

PubMed

Hutton, David W; Sheehan, Peter

2011-04-01

Diabetic lower extremity wounds cause substantial burden to healthcare systems, costing tens of thousands of dollars per episode. Negative pressure wound therapy (NPWT) devices have been shown to be cost-effective at treating these wounds, but the traditional devices use bulky electrical pumps that require a durable medical equipment rental-based procurement process. The Spiracur SNaP™ Wound Care System is an ultraportable NPWT system that does not use an electric pump and is fully disposable. It has superior healing compared to standard of care with modern dressings and comparable healing to traditional NPWT devices while giving patients greater mobility and giving clinicians a simpler procurement process. We used a mathematical model to analyse the costs of the SNaP™ system and compare them to standard of care and electrically powered NPWT devices. When compared to standard of care, the SNaP™ system saves over $9000 per wound treated and more than doubles the number of patients healed. The SNaP system has similar healing time to powered NPWT devices, but saves $2300 in Medicare payments or $2800 for private payers per wound treated. Our analysis shows that the SNaP™ system could save substantial treatment costs in addition to allowing patients greater freedom and mobility. © 2011 The Authors. © 2011 Blackwell Publishing Ltd and Medicalhelplines.com Inc.

Real-world Experience With a Decellularized Dehydrated Human Amniotic Membrane Allograft.

While randomized controlled trials (RCTs) are designed to evaluate efficacy and/or safety under controlled conditions, use of strict inclusion/ exclusion criteria are noted to exclude more than 50% of wound populations. Applicability of RCT outcomes to performance expectations in real-world wound populations raises questions about generalizing their results. The primary aim of this decellularized, dehydrated human amniotic membrane (DDHAM) Use Registry Study was to gain experience and observe outcomes with use of a DDHAM in uninfected, full-thickness, or partial-thickness wounds that, in the investigators' opinions, would benefit from such treatment. Investigators were instructed to provide usual care regarding visit and application frequencies, concomitant therapies, and change in wound-care regimens. The only exclusions were patients with actively infected wounds or known hypersensitivity to DDHAM. Fifteen sites with practicing wound care clinicians of various specialties participated in this review, enrolling chronic wounds including venous, diabetic, pressure, collagen vascular, and arterial ulcers-all of various severities, durations, sizes, and previous treatments. Twenty-eight ulcers studied had failed 32 previous treatments with advanced biologic therapies. A total of 244 wounds were observed in this study, however, this review is limited to the 179 chronic wounds in 165 patients that were enrolled at 15 of the 19 participating centers. The 4 centers that enrolled acute wounds only were excluded. Results from the analysis of this very heterogeneous population demonstrated that during the usual course of an average of 8 weeks of wound management, patients experienced factors that significantly affected wound closure. These factors included wound infections, noncompliance with prescribed treatments (eg, compression, off-loading, and wound care), re-injury of the wound, and systemic comorbidities. Nearly 50% of chronic wounds (including those that failed previous therapy with advanced biologics) with an average baseline area of 3.1 cm2 achieved complete closure within a median of 6.3 weeks without product-related adverse experiences. Despite the challenges of uncontrolled factors that affect healing, this registry study demonstrated the safety and clinical benefit of DDHAM to support wound closure across a variety of chronic wound types and patient conditions in real-world environments.

To develop a conceptual understanding of the decision-making processes used by healthcare professionals in wound care practice. With the global move towards using an evidence-base in standardizing wound care practices and the need to reduce hospital wound care costs, it is important to understand health professionals' decision-making in this important yet under-researched area. A grounded theory approach was used to explore clinical decision-making of healthcare professionals in wound care practice. Interviews were conducted with 20 multi-disciplinary participants from nursing, surgery, infection control and wound care who worked at a metropolitan hospital in Australia. Data were collected during 2012-2013. Constant comparative analysis underpinned by Strauss and Corbin's framework was used to identify clinical decision-making processes. The core category was 'balancing practice-based knowledge with evidence-based knowledge'. Participants' clinical practice and actions embedded the following processes: 'utilizing the best available information', 'using a consistent approach in wound assessment' and 'using a multidisciplinary approach'. The substantive theory explains how practice and evidence knowledge was balanced and the variation in use of intuitive practice-based knowledge versus evidence-based knowledge. Participants considered patients' needs and preferences, costs, outcomes, technologies, others' expertise and established practices. Participants' decision-making tended to be more heavily weighted towards intuitive practice-based processes. These findings offer a better understanding of the processes used by health professionals' in their decision-making in wound care. Such an understanding may inform the development of evidence-based interventions that lead to better patient outcomes. © 2014 John Wiley & Sons Ltd.

Honey is one of the most ancient remedies for wound care. Current research has shown promising results for its use in wound care. This review is intended to inform readers of the physiological properties of honey and the evidence that exists to support its clinical use. When compared with evidence for current wound treatment, honey has proven to be a safe, effective, and sometimes superior treatment for various wounds. There are currently US Food and Drug Administration-approved medical-grade honey products available in the United States. Although there have been no clinical trials exploring the use of honey in wilderness environments, it may be a safe, improvisational wound treatment. More robust studies are needed for definitive conclusions of its efficacy and safety. Published by Wilderness Medical Society on behalf of Wilderness Medical Society.

Wound care and learning disabilities: use of the Avance NPWT system.

Porter, Michelle

Over the past two decades, topical negative pressure wound therapy has gained wide acceptance as a genuine strategy in the treatment algorithm for a wide variety of acute and chronic wounds (Bovill et al, 2008) and over 1000 peer-reviewed publications describing the clinical efficacy and safety of negative pressure wound therapy (NPWT) for all wound types have been published over this period (Vig et al, 2011). Wound care and learning disabilities are very rarely discussed as joint issues. This case study aims to highlight the successful use of topical NPWT on a patient with moderate learning disabilities and examines how wound management should be individualised to meet the needs of the patient.

The integration of information technology into daily patient care potentially provides a means to standardize care and enable continuous quality improvement through improved communication among care teams. A 2-month observational study was conducted on 38 residents with pressure ulcers at a 51-bed skilled nursing facility to rate the Ease of Use and Wound Management Effectiveness of a point-of-care electronic wound documentation system. Nine nurses evaluated the use of handheld "smart phone" devices equipped with a digital camera to document pressure ulcer assessment and treatment at point of care. Ease of Use (five items) was scored on a 5-point Likert scale (5 = very easy); Wound Management Effectiveness (eight items) was scored on a 5-point Likert scale (5 = very effective). Statistically significant mean changes in nurses' ratings were found for baseline compared to 2-month follow-up by paired t-test. Ease of Use ratings across the five criteria increased from an overall mean of 3.3 at baseline to 4.7 at follow-up (P = 0.5), while Wound Management Effectiveness increased from an overall mean of 3.3 at baseline to 4.4 at follow-up (P = 0.5) . The greatest gains for single items were reviewing wound progress (mean difference = 2.35; P = 0.000) and recognizing changes in wound status (mean difference = 1.78; P = 0.001) within the Ease of Use and Wound Management Effectiveness scales, respectively. The smallest change occurred in reading charts and notes (mean difference = 0.89) and ability to determine resident's risk level (mean difference = 0.39). Further research is needed to assess use of a wound documentation system in this and other settings, as well as to ascertain validity and reliability.

The aim of this study was to test the efficacy of a wound support network model between the primary home care service and the hospital. The impact on wound healing rate, cost benefit, and transfer of knowledge was investigated. The intervention group was exposed to a wound support network (n = 32), and the control group continued standard organization of treatment (n = 21). Nonrandomized controlled study; observations were made before (baseline) and after the implementation of the intervention (12 weeks). Patients with chronic wounds (lasting >6 weeks and with wound area >1 cm) in Oslo, Norway. Closure of the observation wound; wound size; total number of wounds; presence of eczema, edema, and pain; number of dressings per week; time spent per dressing; and number of control appointments at the hospital. The economic impact is calculated for the hospital and for the community of Oslo, Norway. The number of control appointments (t = 3.80, P < .001) was significantly decreased, and the number of completed treatments (P = .02) was significantly increased after 12 weeks in the intervention group compared with the control group. A significant improvement was evident in the intervention group in terms of eczema (P = .02), edema (P = .03), and closing of the observational wound (46.7% cases in the intervention group versus 25.0% in the control group). A wound support network between the primary home care service and the hospital is cost-effective, improves clinical efficacy of the home care services' work, and reduces the need for consultations at the hospital.

This multidisciplinary panel of 15 experts in wound healing included podiatrists, wound care specialists (doctors, certified wound care nurses, and research scientists), and an orthopedist. The literature search identified 58 articles, a majority of which were low levels of evidence (69.3% were level 3 or lower). Panel members identified wound types, such as abrasions, burns, stalled wounds, diabetic foot ulcers, and pressure injuries, where ORC/collagen dressing use could be beneficial. Panel members then provided recommendations and technical pearls for the use of ORC/collagen dressings in practice. Barriers to ORC/collagen dressing use were discussed, and potential resolutions were offered. An ORC/collagen dressing can be a critical tool for clinicians to help manage a variety of wounds. Clinical and economic studies comparing standard-of-care dressings and plain collagen dressings to ORC/collagen dressings are needed.

Significance Wound care is an important area of medicine considering the increasing age of the population who may have diverse comorbidities. Light-based technology comprises a varied set of modalities of increasing relevance to wound care. While low-level laser (or light) therapy and photodynamic therapy both have wide applications in wound care, this review will concentrate on the use of ultraviolet (UV) radiation. Recent Advances UVC (200–280 nm) is highly antimicrobial and can be directly applied to acute wound infections to kill pathogens without unacceptable damage to host tissue. UVC is already widely applied for sterilization of inanimate objects. UVB (280–315 nm) has been directly applied to the wounded tissue to stimulate wound healing, and has been widely used as extracorporeal UV radiation of blood to stimulate the immune system. UVA (315–400 nm) has distinct effects on cell signaling, but has not yet been widely applied to wound care. Critical Issues Penetration of UV light into tissue is limited and optical technology may be employed to extend this limit. UVC and UVB can damage DNA in host cells and this risk must be balanced against beneficial effects. Chronic exposure to UV can be carcinogenic and this must be considered in planning treatments. Future Directions New high-technology UV sources, such as light-emitting diodes, lasers, and microwave-generated UV plasma are becoming available for biomedical applications. Further study of cellular signaling that occurs after UV exposure of tissue will allow the benefits in wound healing to be better defined. PMID:24527357

Background About 15% to 25% of people with diabetes will develop a foot ulcer. These wounds are often resistant to healing; therefore, people with diabetes experience lower limb amputation at about 20 times the rate of people without diabetes. If an ulcer does not heal with standard wound care, other therapeutic interventions are offered, one of which is hyperbaric oxygen therapy (HBOT). However, the effectiveness of this therapy is not clearly known. The objectives of this health technology assessment were to assess the safety, clinical effectiveness, and cost-effectiveness of standard wound care plus HBOT versus standard wound care alone for the treatment of diabetic foot ulcers. We also investigated the preferences and perspectives of people with diabetic foot ulcers through lived experience. Methods We performed a review of the clinical and economic literature for the effectiveness and cost-effectiveness of hyperbaric oxygen therapy, as well as the budget impact of HBOT from the perspective of the Ministry of Health and Long-Term Care. We assessed the quality of the body of clinical evidence using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) Working Group criteria. To better understand the preferences, perspectives, and values of patients with diabetic foot ulcers and their experience with HBOT, we conducted interviews and administered an online survey. Results Seven randomized controlled trials and one nonrandomized controlled trial met the inclusion criteria. Comparing standard wound care plus HBOT with standard wound care alone, we found mixed results for major amputation rates (GRADE quality of evidence: low), a significant difference in favour of standard wound care plus HBOT on ulcers healed (GRADE quality of evidence: low), and no difference in terms of adverse events (GRADE quality of evidence: moderate). There is a large degree of uncertainty associated with the evaluation of the cost-effectiveness of standard wound care plus HBOT. However, results appear to suggest that this treatment results in lower costs and better outcomes than standard wound care alone. Funding HBOT will result in a budget impact of $4 million per year in immediate treatment costs for the Ontario Ministry of Health and Long-Term Care. This cost decreases to $0.5 million per year when downstream costs are considered. There is a substantial daily burden of care and emotional weight associated with living with diabetic foot ulcers, both of which are compounded by concern regarding possible amputation. Patients feel that HBOT is an effective treatment and reported that they were satisfied with how their ulcers healed and that this improved their quality of life. Conclusions The evidence makes it difficult to draw any definitive conclusions on the clinical and cost effectiveness of standard wound care plus HBOT versus standard wound care alone for the treatment of diabetic foot ulcers.

Fresh traumatic wound is a common health problem in patients attending Trauma Center at Siriraj Hospital in Bangkok, Thailand. Antibiotic prophylaxis was given to nearly 90% of such patients. A contributing factor to a high prevalence of antibiotic prophylaxis is a lack of data on bacterial contamination at fresh traumatic wounds in Thai patients. To determine prevalence and characters of bacterial contamination, and incidence of wound infection in adult patients with fresh traumatic wounds attending Siriraj Trauma Center. Prospective study was conducted in 330 adult patients with fresh traumatic wounds from March 2012 and September 2012. All patients received wound care and antibiotic prophylaxis according to the judgment of their responsible physicians. A wound swab culture was taken from all patients. The patients were either called by telephone or asked to have follow-up visits in order to determine incidence of wound infection. The infected patient received regular care. Sixty-three percent and 8% of the patients had lacerated wounds and bite wounds, respectively. Ninety-one percent of them received antibiotics of which dicloxacillin and co-amoxiclav accounted for 80.3% and 11.4%, respectively. Wound swab cultures revealed that potential pathogenic bacteria i.e. S. aureus, streptococci, Enterobacteriaceae, Aeromonas spp., Acinetobacter spp. and non-fermentative gram-negative rods (NF GNR) were recovered from 7% of wounds. Incidence of wound infection was 1.2%, and all infected wounds were found in patients who had a contaminated wound and received antibiotic prophylaxis. Bacterial contaminations of infected patients were NF GNR, E. cloacae, and mixed organisms. All wound infections were successfully treated with appropriate wound care. More than 90% of adult patients with fresh traumatic wound at Siriraj Trauma Center received prophylactic antibiotics. Less than 10% of these wounds were contaminated with potentially pathogenic bacteria. Incidence of wound infection in fresh traumatic wounds was low.

Epidemiological approach to surgical management of the casualties of war.

Coupland, R. M.

The nature of modern conflicts precludes adequate medical care for most people wounded in wars. The traditional military approach of echeloned care for those wounded on the battlefield has limited relevance. I present an alternative, epidemiological approach whereby some effective care may reach many more. For a surgical facility to have a positive impact by using surgical and anaesthetic competence there must be access to the wounded; security for staff and patients; and a functioning hospital infrastructure. These all depend on respect for the first Geneva convention. Early hospital admission for urgent surgery is not so important if there is adequate first aid beforehand. The hospitals of the International Committee of the Red Cross have provided surgical care for thousands of wounded people by fulfilling these conditions. People wounded in modern conflicts would fare better if these priorities were recognised and less emphasis was placed on the more spectacular aspects of surgical care that benefit only a few.

Community health nursing, wound care, and...ethics?

PubMed

Bell, Sue Ellen

2003-09-01

Because of changing demographics and other factors, patients receiving care for wounds, ostomies, or incontinence are being referred in increasing numbers to community health nursing organizations for initial or continued care. As home-based wound care becomes big business, little discussion is being focused on the moral and ethical issues likely to arise in the high-tech home setting. Progressively more complex and expensive home care relies on family members to take on complicated care regimens in the face of decreasing numbers of allowable skilled nursing home visits. A framework and a principle-based theory for reflection on the character and content of moral and ethical conflicts are provided to encourage informed and competent care of patients in the home. Common moral and ethical conflicts for WOC nurses in the United States are presented. These conflicts include issues of wound care supply procurement; use of documentation to maximize care or profit; problems of quality, care consistency, and caregiver consent; and dilemmas of tiered health care options. The advantages of a framework to address ethical conflicts are discussed.

Children's experiences of procedural pain management in conjunction with trauma wound dressings.

This paper is a report of the experiences of children (5-10 years) of procedural pain when they underwent a trauma wound care session. Procedural pain in conjunction with trauma wound care often induces anxiety and distress in children. Children need to alleviate pain and avoid the development of fear in conjunction with examinations and treatments. The nurse could help children to reach this goal by using the comfort theory, which describes holistic nursing in four contexts: physical, psychospiritual, environmental and sociocultural. Few studies have focused on children's experiences of comforting activities in conjunction with trauma wound dressings. This study was conducted between May 2008 and January 2010. Thirty-nine participants aged 5-10 were consecutively included in this study. The wound care session was standardized for all the participants, and semi-structured qualitative interviews with open-ended questions were conducted with all the children in conjunction with the procedure. All the interviews were transcribed verbatim and analysed with qualitative content analysis. Four themes were identified: clinical competence, distraction, participation and security. The children were helped to reach comforting activities to enhance pain management. Children require more than just analgesics in wound care. They also need to experience security and participation in this context. When children feel clinical competence in wound care, they trust the nurse to carry out the wound dressing and instead can focus on the distraction that increases their positive outcomes. © 2011 Blackwell Publishing Ltd.

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.

Preparation and use of a newly developed pH 4.3 horizontal thin layer acrylamide gel which permits the simultaneous separation of acidic and basic isoperoxidases in up to 30 samples is described. Use of cytochrome c, horseradish peroxidase, and a purified potato isoperoxidase as internal standards for a range in isoelectric points of peroxidases from pH 3 to 11 is introduced to facilitate comparison of results obtained with different materials and different methods. Distribution of tissue-specific isoperoxidases in different cell layers of wounded potato (Solanum tuberosum L.) tissue is shown and their purification described. Evidence for the in vitro degradation of basic potato isoperoxidases resulting in more acidic forms similar to isoperoxidases occurring in wounded potato tissue is presented. The significance of this observation for the postulated differential function of different isoperoxidases is discussed. ImagesFig. 1-3 PMID:16660608

Many wound care centers (WCCs) provide a specialized level of care using various wound care therapies and are managed by quali ed healthcare professionals (QHPs) from di erent specialty backgrounds such as family medicine, podiatry, and plastic surgery. However, these QHPs are sometimes challenged by reimbursement issues, limited therapy and dressing options, reduced access to multidisciplinary team members, and cost-driven factors unique to WCCs. To help address these issues, a meeting was convened by an expert panel of WCC physicians to discuss best practices for treating complex patients in a WCC. This publication presents an overview of WCC chal- lenges, describes a holistic approach to treating WCC patients, and provides clinical guidance on the decision-mak- ing process for selecting optimal treatment plans for the WCC patient. Clinical cases of atypical, surgical and chronic wounds seen in a WCC are also presented.

We described a health care-associated Serratia marcescens outbreak of wound and soft tissue infection lasting approximately 11 months at Ankara University Ibni Sina Hospital. After identification of S marcescens strains from the clinical and environmental samples, and their susceptibility testing to antimicrobial agents, pulsed-field gel electrophoresis (PFGE) was performed to detect molecular epidemiologic relationships among these isolates. The strains which were isolated from the saline bottles used for wound cleansing in the wound care unit were found to be 100% interrelated by PFGE to the strains from the samples of the outbreak patients. Reuse of the emptied bottles has no longer been allowed since the outbreak occurred. Besides, more efficient and frequent infection control training for hospital staff has been conducted.

Evaluation of Epidermal Skin Grafts for the Treatment of Complex Wounds in a Wound Care Center: A 94-Patient Case Series.

PubMed

Lincoln, Katherine; Hyde, Jessica

2016-10-01

In recent years, a new technology for autologous epidermal harvesting has been developed to produce epidermal skin grafts (ESGs) for use over wounds. This technology employs negative pressure and heat to raise the epidermal skin layer, allowing for consistent and reproducible epidermal harvesting. The aim of this case series is to present the authors' experience using an automated, epidermal harvesting system to produce ESGs to treat wounds of patients with multiple comorbidities. This case series was conducted between January 1, 2013 and December 31, 2014. Patients with wounds (≤ 25 cm2) that failed to heal were treated with ESGs by a group of 3 wound care physicians in 2 outpatient wound care centers in a community health center setting. A total of 94 patients with 102 wounds were identified. Of the 94 patients, 3 were noncompliant and 9 were lost to follow-up. Therefore, 82 patients with 90 wounds were included in the analysis. The majority of wounds demonstrated epithelialization (83/90, 92.2%). Of the 90 wounds, 75 (83.3%) healed following epidermal grafting, 4 (4.4%) wounds displayed improvement, and 11 (12.2%) did not heal. Minimal or no pain at the donor site was reported by the patients, and all donor sites healed without complications. This case series provides additional evidence for the use of ESGs for the treatment of wounds that fail to heal.

The Combat Wound Initiative (CWI) program is a collaborative, multidisciplinary, and interservice public-private partnership that provides personalized, state-of-the-art, and complex wound care via targeted clinical and translational research. The CWI uses a bench-to-bedside approach to translational research, including the rapid development of a human extracorporeal shock wave therapy (ESWT) study in complex wounds after establishing the potential efficacy, biologic mechanisms, and safety of this treatment modality in a murine model. Additional clinical trials include the prospective use of clinical data, serum and wound biomarkers, and wound gene expression profiles to predict wound healing/failure and additional clinical patient outcomes following combat-related trauma. These clinical research data are analyzed using machine-based learning algorithms to develop predictive treatment models to guide clinical decision-making. Future CWI directions include additional clinical trials and study centers and the refinement and deployment of our genetically driven, personalized medicine initiative to provide patient-specific care across multiple medical disciplines, with an emphasis on combat casualty care.

Abstract To assess the feasibility of a wound care model using 4th-generation mobile communication technology standards (4G) with smart phones or smart glasses for wound management. This wound care model is an interactive, real-time platform for implementing telemedicine changing wound dressings, or doing operations. It was set up in March 2015 between Jinhua in Zhejiang province and Shanghai, China, which are 328 km apart. It comprised of a video application (APP), 4G net, smart phones or smart glasses, and a central server. This model service has been used in 30 patients with wounds on their lower extremities for 109 times in 1 month. Following a short learning curve, the service worked well and was deemed to be user-friendly. Two (6.7%) patients had wounds healed, while others still required wound dressing changes after the study finished. Both local surgeons and patients showed good acceptance of this model (100% and 83.33%, respectively). This telemedicine model is feasible and valuable because it provides an opportunity of medical service about wound healing in remote areas where specialists are scarce. PMID:27495023

Objective: To test whether the use of a wireless electroceutical dressing (WED) (Procellera®) in conjunction with a 5-day negative pressure wound therapy (NPWT) may reduce the number of dressing changes required per week with this therapy. Approach: At the Ohio State University Comprehensive Wound Center, chronic wound patients (n=30) undergoing NPWT were randomized into two arms following consent as approved by the institutional review board. The control arm received standard of care NPWT, where the dressing change was performed thrice a week. The test arm received the same care except that the WED was added as an interface layer and dressing change was limited to twice a week. Results: A reduced cost of care was achieved using the WED in conjunction with NPWT. Despite fewer dressing changes in wounds dressed with the WED, closure outcomes were comparable with no overt signs of any wound complication, including infection. The cost of NPWT care during the week was significantly lower (from $2918 to $2346) in the WED-treated group compared with patients in the control arm. Innovation: This work introduces a novel technology platform involving a WED, which may be used in conjunction with NPWT. If used as such, NPWT is effective in decreasing the frequency of dressing change and lowering the cost of care. Conclusion: This work points toward the benefit of using the WED combined with NPWT. A larger clinical trial investigating the cost-effectiveness of WED in wound care is warranted. PMID:26005596

The doctrine on wounds is the most important and current one in general surgery and reflects the level and development of medicine. Each surgeon should be well acquainted with all processes and stages of wound healing, because treatment of a suppurative wound requires keen knowledge and art. The basic principle of the local treatment of a septic wound is the thorough knowledge on the objective criteria underlying the course of the wound process and on the etiopathogenetic therapy. Laser therapy of wounds accomplishes adequate necrotomy, acts aseptically on the wound surfaces, inhibits the wound microbial flora and stimulates the regeneration processes. The authors record their experience in CO2 laser and helium-neon treatment of 120 patients with suppurative, atonic and decubital wounds over the period 1984-1990.

Chronic non-healing wounds challenge tissue regeneration and impair infection regulation for patients afflicted with this condition. Next generation wound care technology capable of in situ physiological surveillance which can diagnose wound parameters, treat various chronic wound symptoms, and reduce infection at the wound noninvasively with the use of a closed loop therapeutic system would provide patients with an improved standard of care and an accelerated wound repair mechanism. The indicating biomarkers specific to chronic wounds include blood pressure, temperature, oxygen, pH, lactate, glucose, interleukin-6 (IL-6), and infection status. A wound monitoring device would help decrease prolonged hospitalization, multiple doctors' visits, and the expensive lab testing associated with the diagnosis and treatment of chronic wounds. A device capable of monitoring the wound status and stimulating the healing process is highly desirable. In this review, we discuss the impaired physiological states of chronic wounds and explain the current treatment methods. Specifically, we focus on improvements in materials, platforms, fabrication methods for wearable devices, and quantitative analysis of various biomarkers vital to wound healing progress.

This paper reports the characteristics and local management of 826 acute wounds identified during an audit across all health care providers serving the population of Bradford, UK. Of the wounds encountered 303 were traumatic wounds and 237 primary closures with smaller numbers of other acute wound types. Of the 303 traumatic wounds 174 occurred in women (57.4%). Men predominated in the under 45s (65M:26F), this being largely accounted for by hand and finger trauma (n = 62) particularly in patients of working age (M32:F12). Women predominated in the over 65s (50M:130F), this being largely accounted for by lower limb traumatic wounds (M24:F91), the majority of these being in patients 65 and over (M14:F82). In this sub-group of 96 patients 25 had wounds of 6 weeks or longer duration, only 3 had undergone Doppler assessment and only 2 received compression bandaging. Typically these wounds were of recent origin and small in size (under 1 week and less than 5 cm2 in surface area) however exceptions occurred where 10 people had wounds over 25 cm2 in area while 3 wounds had been present for over 5 years. 101 (12.2%) of the encountered wounds were considered to be infected although the practice of wound swabbing in the presence of presumed infection seemed inadequate with 37.6% of all infected acute wounds not being swabbed while 97 non-infected wounds were swabbed. Where wounds were swabbed 4.5% were found to be MRSA positive. Across all acute wound types (with the sole exception of primary closures) antimicrobial wound dressings were the most prevalent form of dressing and covered 56 (55.4%) of all infected wounds.

Telemedicine coupled with digital photography could potentially improve the quality of outpatient wound care and decrease medical cost by allowing home care nurses to electronically transmit images of patients' wounds to treating surgeons. To determine the feasibility of this technology, we compared bedside wound examination by onsite surgeons with viewing digital images of wounds by remote surgeons. Over 6 weeks, 38 wounds in 24 inpatients were photographed with a Kodak DC50 digital camera (resolution 756 x 504 pixels/in2). Agreements regarding wound description (edema, erythema, cellulitis, necrosis, gangrene, ischemia, and granulation) and wound management (presence of healing problems, need for emergent evaluation, need for antibiotics, and need for hospitalization) were calculated among onsite surgeons and between onsite and remote surgeons. Sensitivity and specificity of remote wound diagnosis compared with bedside examination were calculated. Potential correlates of agreement, level of surgical training, certainty of diagnosis, and wound type were evaluated by multivariate analysis. Agreement between onsite and remote surgeons (66% to 95% for wound description and 64% to 95% for wound management) matched agreement among onsite surgeons (64% to 85% for wound description and 63% to 91% for wound management). Moreover, when onsite agreement was low (i.e., 64% for erythema) agreement between onsite and remote surgeons was similarly low (i.e., 66% for erythema). Sensitivity of remote diagnosis ranged from 78% (gangrene) to 98% (presence of wound healing problem), whereas specificity ranged from 27% (erythema) to 100% (ischemia). Agreement was influenced by wound type (p < 0.01) but not by certainty of diagnosis (p > 0.01) or level of surgical training (p > 0.01). Wound evaluation on the basis of viewing digital images is comparable with standard wound examination and renders similar diagnoses and treatment in the majority of cases. Digital imaging for remote wound management is feasible and holds significant promise for improving outpatient vascular wound care.

The skin provides essential functions, such as thermoregulation, hydration, excretion and synthesis of vitamin D. Major disruptions of the skin cause impairment of critical functions, resulting in high morbidity and death, or leave one with life-changing cosmetic damage. Due to the complexity of the skin, diverse approaches are needed, including both traditional and advanced, to improve cutaneous wound healing. Cutaneous wounds undergo four phases of healing. Traditional management, including skin grafts and wound dressings, is still commonly used in current practice but in combination with newer technology, such as using engineered skin substitutes in skin grafts or combining traditional cotton gauze with anti-bacterial nanoparticles. Various upcoming methods, such as vacuum-assisted wound closure, engineered skin substitutes, stem cell therapy, growth factors and cytokine therapy, have emerged in recent years and are being used to assist wound healing, or even to replace traditional methods. However, many of these methods still lack assessment by large-scale studies and/or extensive application. Conceptual changes, for example, precision medicine and the rapid advancement of science and technology, such as RNA interference and 3D printing, offer tremendous potential. In this review, we focus on the basics of wound treatment and summarize recent developments involving both traditional and hi-tech therapeutic methods that lead to both rapid healing and better cosmetic results. Future studies should explore a more cost-effective, convenient and efficient approach to cutaneous wound healing.

In the rural Midwest region of Western Australia (WA), wound care is a major burden on the healthcare system. Optimal wound care was found to be impeded by issues that included the involvement of multiple healthcare providers, incomplete and inconsistent documentation, and limited access to expert review. A telehealth solution was trailed in 2007. To describe the systemic barriers encountered in implementing a telehealth program in rural WA and to provide recommendations for future telehealth initiatives. This study trialled the use of a shared electronic wound imaging and reporting system in combination with an expert remote wound consultation service for the management of patients with chronic wounds in the Midwest of WA. The trial sites included rural hospital out-patient clinics, a private domiciliary nursing service, residential aged care facilities, general practices and a podiatry clinic. The implementation conformed to accepted best practice in introducing telehealth initiatives. During the trial 12 sites had the relevant software installed and were able to access a central server. Although a total of 41 patients with chronic wounds were enrolled, four sites did not enroll any patients and only two sites successfully incorporated the system into regular practice. Major obstacles were workforce issues and significant delays in installing the software at some sites. Only 47% of the healthcare providers trained to use the software at the beginning of the trial were still employed when the trial ended. Prolonged periods of vacant positions at one remote clinic and an aged care facility made it impossible for the remaining providers to allocate time for using the wound care software. The disease burden of the patient group, funding models and workforce shortages frustrated the successful adoption of an evidence based strategy that was known to improve health outcomes.

Skin abscesses are a frequent encountered health care problem and lead to a significant source of morbidity. They consequently have an essential impact on the quality of life and work. To date, the type of aftercare for surgically drained abscesses remains under debate. This leads to undesirable practice variations. Many clinical standard protocols include sterile wound dressings twice a day by a home-care service to reduce the chance of a recurrent wound infection. It is unknown, however, whether reinfection rates are comparable to adequate wound irrigation with a nonsterile solution performed by the patient. Our hypothesis is that simple wound irrigation with nonsterile water for postoperative wound care after an abscess is surgically drained is feasible. We assume that in terms of reinfection and reintervention rates unsterile wound irrigation is equal to sterile wound irrigation. The primary aim of this study is therefore to investigate if there is a need for sterile wound irrigation after surgically drained spontaneous skin abscesses. In a prospective, randomized controlled, single-blinded, single-center trial based on a noninferiority design, we will enroll 128 patients randomized to either the control or the intervention group. The control group will be treated according to our current, standard protocol in which all patients receive a sterile wound irrigation performed by a home-care service twice a day. Patients randomized to the intervention group will be treated with a nonsterile wound irrigation (shower) twice a day. All patients will have a routine clinical control visit after 1, 3, 6, and 12 weeks in the outpatient clinic. Primary outcome is the reinfection and reoperation rate due to insufficient wound healing diagnosed either at the outpatient control visit or during general practitioner visits. Secondary outcome measures include a Short Form Health Survey, Visual Analog Scale, Patient and Observer Scar Assessment Scale, Vancouver Scar Scale, and the EurolQol 5-Dimension Questionnaire. Those questionnaires will be completed at the outpatient control visits. The trial was started in June 2016 and enrolled 50 patients by article publication. Regarding the adherence to our protocol, we found 10% of loss to follow-up until now. Only 2 patients needed reoperation and only 1 patient needed a change of treatment (antiseptic therapy). Most patients are happy with their randomized treatment but as expected some patients in the sterile group complained about timing problems with their working hours and home-care service appointments. Most patients in the nonsterile group are satisfied being able to take care of their wounds independently although some patients still depend on the home-care service for the wound dressing. We are hoping to have enrolled enough patients by summer 2017. The follow-up will take until autumn 2017, and study results are expected to be published by the end of 2017. This trial is solely supported by the cantonal hospital of Lucerne. Nonsterile wound irrigation is more likely to be carried out independently by the patient than sterile wound irrigation. Therefore, if nonsterile wound care shows comparable results in terms of reinfection and reintervention rates, patient independence in the aftercare of surgically drained abscesses will increase, patients can return to work earlier, and health care costs can be reduced. In a preliminary, conservative estimation of health care costs, an annual savings of 300,000 CHF will be achieved in our hospital.

The aim of this study was to determine the cost of chronic wound care for Medicare beneficiaries in aggregate, by wound type and by setting. This retrospective analysis of the Medicare 5% Limited Data Set for calendar year 2014 included beneficiaries who experienced episodes of care for one or more of the following: arterial ulcers, chronic ulcers, diabetic foot ulcers, diabetic infections, pressure ulcers, skin disorders, skin infections, surgical wounds, surgical infections, traumatic wounds, venous ulcers, or venous infections. The main outcomes were the prevalence of each wound type, Medicare expenditure for each wound type and aggregate, and expenditure by type of service. Nearly 15% of Medicare beneficiaries (8.2 million) had at least one type of wound or infection (not pneumonia). Surgical infections were the largest prevalence category (4.0%), followed by diabetic infections (3.4%). Total Medicare spending estimates for all wound types ranged from $28.1 to $96.8 billion. Including infection costs, the most expensive estimates were for surgical wounds ($11.7, $13.1, and $38.3 billion), followed by diabetic foot ulcers ($6.2, $6.9, and $18.7 billion,). The highest cost estimates in regard to site of service were for hospital outpatients ($9.9-$35.8 billion), followed by hospital inpatients ($5.0-$24.3 billion). Medicare expenditures related to wound care are far greater than previously recognized, with care occurring largely in outpatient settings. The data could be used to develop more appropriate quality measures and reimbursement models, which are needed for better health outcomes and smarter spending for this growing population.

Fundamental principles in periodontal plastic surgery and mucosal augmentation--a narrative review.

PubMed

Burkhardt, Rino; Lang, Niklaus P

2014-04-01

To provide a narrative review of the current literature elaborating on fundamental principles of periodontal plastic surgical procedures. Based on a presumptive outline of the narrative review, MESH terms have been used to search the relevant literature electronically in the PubMed and Cochrane Collaboration databases. If possible, systematic reviews were included. The review is divided into three phases associated with periodontal plastic surgery: a) pre-operative phase, b) surgical procedures and c) post-surgical care. The surgical procedures were discussed in the light of a) flap design and preparation, b) flap mobilization and c) flap adaptation and stabilization. Pre-operative paradigms include the optimal plaque control and smoking counselling. Fundamental principles in surgical procedures address basic knowledge in anatomy and vascularity, leading to novel appropriate flap designs with papilla preservation. Flap mobilization based on releasing incisions can be performed up to 5 mm. Flap adaptation and stabilization depend on appropriate wound bed characteristics, undisturbed blood clot formation, revascularization and wound stability through adequate suturing. Delicate tissue handling and tension free wound closure represent prerequisites for optimal healing outcomes. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The wound healing trajectory and predictors with combined electric stimulation and conventional care: one outpatient wound care clinic's experience.

Zhou, Kehua; Schenk, Ronald; Brogan, Michael S

2016-12-01

Electric stimulation (E-stim) has been found to be an effective treatment in improving wound healing rates. However, the wound healing trajectory and its related predictors for complete wound closure (CWC) have not been reported with E-stim treatment. This was a retrospective study. Data on 159 patients treated at an outpatient wound clinic utilizing combined intervention of E-stim and conventional care were included. The Kaplan-Meier healing curve together with linear regression models depicted the percentage of patients with CWC against time. With 100, 112 and 140 days of treatment, the percentages of patients with CWC were 59·12%, 61·01% and 65·41%, respectively. Linear regression models predicted that all patients would achieve CWC by 21·55, 22·26 and 24·80 weeks, respectively. The speed for the increase in the number and percentage of patients with CWC peaked between 50-75 days of treatment. To optimize timely healing, referral to other treatment facilities or change of treatment protocol is warranted around the peak time. With the combined intervention of E-stim and conventional care, positive predictors for CWC included a shorter wound duration at initial evaluation (P = 0·005, OR = 3·10), better compliance with appointments (P = 0·007, OR = 3·38) and the diagnosis of venous leg ulcer (P = 0·001, OR = 3·88). This study provided preliminary data on wound healing trajectory and predictors with combined E-stim and conventional care. E-stim seemed to expedite wound healing; however, further research studies are needed. © 2016 Stichting European Society for Clinical Investigation Journal Foundation.

Factors Associated with Shooting Accuracy and Wounding Rate of Four Managed Wild Deer Species in the UK, Based on Anonymous Field Records from Deer Stalkers

PubMed Central

Aebischer, Nicholas J.; Wheatley, Christopher J.; Rose, Hugh R.

2014-01-01

The amount of wounding during routine culling is an important factor in the welfare of wild deer. Little information exists on factors determining shooting accuracy and wounding rates under field conditions in the UK. In this study, 102 anonymous stalkers collected data on the outcomes and circumstances of 2281 shots. Using hot-deck imputation and generalised linear mixed modelling, we related the probability that a shot hit its target, and the probability that the shot killed the deer if it was hit, to 28 variables describing the circumstances of the shot. Overall, 96% of deer were hit, of which 93% were killed outright. A reduced probability of hitting the target was associated with an uncomfortable firing position, too little time available, shooting off elbows or freehand, taking the head or upper neck as point of aim, a heavily obscured target, a distant target, shooting at females, lack of shooting practice and a basic (or no) stalker qualification. An increase in the likelihood of wounding was associated with an uncomfortable firing position, shooting with insufficient time, a distant target (only when time was not sufficient), a bullet weight below 75 grains, a target concealed in thicket or on the move and an area rarely stalked. To maximise stalking success and deer welfare, we recommend that stalkers ensure a comfortable firing position, use a gun rest, aim at the chest, use bullets heavier than 75 grains, avoid taking a rushed shot, shoot a distant animal only if there is plenty of time, fire only when the target is stationary, avoid shooting at an obscured animal, take care when the ground is unfamiliar, and do shooting practice at least once a month. The high miss rate of basic-level stalkers suggests that training should include additional firing practice under realistic shooting conditions. PMID:25334012

An innovative enterostomal therapy nurse model of community wound care delivery: a retrospective cost-effectiveness analysis.

PubMed

Harris, Connie; Shannon, Ronald

2008-01-01

A Canadian specialty nursing association identified the necessity to examine the role and impact of enterostomal (ET) nursing in Canada. We completed a retrospective analysis of the cost-effectiveness and benefits of ET nurse-driven resources for the treatment of acute and chronic wounds in the community. This was a multicenter retrospective pragmatic chart audit of 3 models of nursing care utilizing 4 community nursing agencies and 1 specialty company owned and operated by ET nurses. An analysis was completed using quantitative methods to evaluate healing outcomes, nursing costs, and cost-effectiveness. Kaplan-Meier estimates were calculated to determine the average time to 100% healing of acute and chronic wounds and total nursing visit costs for treatment in a community setting. Average direct nursing costs related to management of each wound were determined by number of nursing visits and related reimbursement for each visit. A Monte Carlo simulation method was used to help account for costs and benefits in determination of cost-effectiveness between caring groups and the uncertainty from variation between patients and wounds. Three hundred sixty chronic wounds and 54 acute surgical wound charts were audited. Involvement of a registered nurse (RN) with ET or advanced wound ostomy skills (AWOS) in community-level chronic and acute wound care was associated with lower overall costs mainly due to reduced time to 100% closure of the wound and reduced number of nursing visits. The differences in health benefits and total costs of nursing care between the ET/AWOS and a hybrid group that includes interventions developed by an ET nurse and followed by general visiting nurses that could include both RNs and registered practical nurses is an expected reduction in healing times of 45 days and an expected cost difference of $5927.00 per chronic wound treated. When outcomes were broken into ET/AWOS involvement categories for treatment of chronic wounds, there was a significantly faster time to 100% closure at a lower mean cost as the ET/AWOS involvement increased in the case. For acute wound treatment, the differences in health benefits and total costs between the ET/AWOS and a hybrid nursing care model were an expected reduction in healing times of 95 days and an expected cost difference of $9578.00 per acute wound treated. Again, there was a significant difference in healing times and reduced mean cost as the ET/AWOS became more involved in the treatment. The financial benefit to the Ontario Ministry of Health and Long-Term Care is estimated to increase as the involvement of nurses with ET/AWOS specialty training increases. The greater the involvement both directly and indirectly of an ET/AWOS nurse in the management of wounds, the greater the savings and the shorter the healing times.

The national health-care agenda in relation to negative pressure wound therapy.

PubMed

Sinha, Surajit; Mudge, Elizabeth

2013-09-01

The NHS was founded upon the principle of providing health care for all, regardless of financial status. However, it has reached a point where patient demands are outgrowing NHS resources, causing conflict. Chronic wound management represents a considerable financial burden on health services in terms of manpower requirement, equipment, specialist opinion, and adjunct therapies, such as negative pressure wound therapy (NPWT). Although funding bodies often perceive NPWT to be expensive, there is evidence that if used appropriately it leads to faster healing, early discharge and better quality of life for patients with chronic wounds. However, it must be acknowledged that the type and quality of studies are mixed. Further evidence is required to justify the use of NPWT in chronic wounds in the primary and secondary health-care setting.

The principle difference of the work of multiprofile military hospitals (MMH) of the Ist level during the armed conflicts on the Northern Caucasus, particularly during the second, was rendering specialized surgical care to the primary contingent of the wounded, evacuated during the nearest hours after a wound. The incoming flow to MMH of the 1st level - in connection with the primary entering of the wounded practically from a battle field - was characterized by severity (one third of the wounded had severe and extremely severe wounds) and the significant number of the wounded with multiple and combined injuries (up to 60% of the wounded). Effective treatment of the above-mentioned wounded can only be carried by specially trained surgeons in appropriately-equipped multiprofile medical hospitals. The rendered volume of specialized surgical care in MMH of the 1st level included the following operations: neurosurgical (2,4%), thoracoabdominal (19,8%), traumatologic (17,0%), angiosurgical (8,2%), special (otorhinolaryngologic, maxillofacial, ophthalmologic, urologic) - 17,7%, general surgery (35,4%). During the armed conflict of 1999-2002 due to the introduction of the early specialized surgical care concept three MMH of the 1st level in the advanced way executed 86,4 % of all complex operations in medical units and hospitals of the combat zone.

Maintaining good hospital records during military conflicts can provide medical personnel and researchers with feedback to rapidly adjust treatment strategies and improve outcomes. But to convert the resulting raw data into meaningful conclusions requires clear terminology and well thought out equations, utilizing consistent numerators and denominators. Our objective was to arrive at terminology and equations that would produce the best insight into the effectiveness of care at different stages of treatment, either pre or post medical treatment facility care. We first clarified three essential terms: 1) the case fatality rate (CFR) as percentage of fatalities among all wounded; 2) killed in action (KIA) as percentage of immediate deaths among all seriously injured (not returning to duty); and 3) died of wounds (DOW) as percentage of deaths following admission to a medical treatment facility among all seriously injured (not returning to duty). These equations were then applied consistently across data from the WWII, Vietnam and the current Global War on Terrorism. Using this clear set of definitions we used the equations to ask two basic questions: What is the overall lethality of the battlefield? How effective is combat casualty care? To answer these questions with current data, the three services have collaboratively created a joint theater trauma registry (JTTR), cataloging all the serious injuries, procedures, and outcomes for the current war. These definitions and equations, consistently applied to the JTTR, will allow meaningful comparisons and help direct future research and appropriate application of personnel.

Delivering and documenting evidence-based treatment to all Department of Veterans Affairs (VA) foot ulcer patients has wide appeal. However, primary and secondary care medical centers where 52% of these patients receive care are at a disadvantage given the frequent absence of trained specialists to manage diabetic foot ulcers. A retrospective review of diabetic foot ulcer patient records and a provider survey were conducted to document the foot ulcer problem and to assess practitioner needs. Results showed of the 125 persons with foot ulcers identified through administrative data, only, 21% of diabetic foot patients were correctly coded. Chronic Care and Microsystem models were used to prepare a tailored intervention in a VA primary care medical center. The site Principal Investigators, a multidisciplinary site wound care team, and study investigators jointly implemented a diabetic foot ulcer program. Intervention components include wound care team education and training, standardized good wound care practices based on strong scientific evidence, and a wound care template embedded in the electronic medical record to facilitate data collection, clinical decision making, patient ordering, and coding. A strategy for delivering offloading pressure devices, regular case management support, and 24/7 emergency assistance also was developed. It took 9 months to implement the model. Patients were enrolled and followed for 1 year. Process and outcome evaluations are on-going.

Just as it takes a team to manage chronic wounds, it takes a team to maintain the CDM. The technical staff from the wound care department should be represented on this team and should share the appropriate HCPCS codes and CPT codes, product descriptions, and costs for all procedures, services, supplies, drugs, and biologics used in their department. The billing department should ensure that the appropriate revenue codes for each payer are listed for each item on the CDM. Based on costs supplied by the wound care department, the finance department should consistently assign hospital charges to each line item on the CDM. The information technology department is responsible for making the specific changes to the CDM in the computer system. Most hospitals have a CDM coordinator. The technical staff from the wound care department should work closely with the CDM coordinator and should obtain from him/her the policies and procedures for maintaining the wound care department CDM. Most CDM coordinators will also provide a CDM Change Request Form. Use that form each year when the hospital is performing its annual CDM maintenance and throughout the year to add procedures, services, supplies, drugs, or biologics to your wound care offerings and/or when the cost for these offerings change.

Standards for basic documentation and the course of treatment increase quality assurance and efficiency in health care. To date, no standards for the treatment of patients with leg ulcers are available in Germany. The aim of the study was to develop standards under routine conditions in the documentation of patients with leg ulcers. This article shows the recommended variables of a "standard dataset" and a "minimum dataset". Consensus building among experts from 38 scientific societies, professional associations, insurance and supply networks (n = 68 experts) took place. After conducting a systematic international literature research, available standards were reviewed and supplemented with our own considerations of the expert group. From 2012-2015 standards for documentation were defined in multistage online visits and personal meetings. A consensus was achieved for 18 variables for the minimum dataset and 48 variables for the standard dataset in a total of seven meetings and nine online Delphi visits. The datasets involve patient baseline data, data on the general health status, wound characteristics, diagnostic and therapeutic interventions, patient reported outcomes, nutrition, and education status. Based on a multistage continuous decision-making process, a standard in the measurement of events in routine care in patients with a leg ulcer was developed.

The purpose of this study is to report the Chinese experience of establishing hospital-based wound care centers over 15 years. A total of 69 wound-healing centers (WHCs) and wound care units (WCUs) were involved. Questionnaires were diverged to the principal directors of these sites; data extracted for this study included origin, year of establishment, medical staff, degree of hospitals, wound etiology, wound-healing rate, hospital stay, and outcomes data. The period of data extraction was defined as before and after 1 year of the establishment of WHCs and WCUs. The earliest WHC was established in 1999, and from 2010 the speeds of establishing WHCs and WCUs rapidly increased. The majority of WHCs were divisions of burn departments, and all WHCs came from departments of outpatient dressing rooms. Full-time multidisciplinary employees of WHCs differed greatly to WCUs. Types of wound and outcomes vary with those of centers reported from Western countries and the United States. Improvement in wound healing caused by the establishment of WHCs and WCUs in China occurred without doubt. Some advices include the following: rearrange and reorganize the distribution of WHCs and WCUs; enact and generalize Chinese guidelines for chronic wounds; utilize medical resources reasonably; improve multidisciplinary medical staff team; draw up and change some medical and public policies and regulations. © The Author(s) 2015.

The wound debrider: a new monofilament fibre technology.

PubMed

Haemmerle, Gilbert; Duelli, Heinz; Abel, Martin; Strohal, Robert

Debridement is a basic necessity to induce the functional process of tissue repair, especially in chronic wounds. In this pilot study the authors used a new debrider technology with specific monofilament fibres in a unique texture to evaluate its efficacy, safety and tolerability. In eleven patients, exhibiting all types of wound-associated debris (biofilms, slough, necrotic crusts and hyperkeratotic plaques), the debrider, wetted with physiological solution, was wiped without specific force over the wound for about 2-4 minutes. This led to removal of almost all debris leaving healthy granulation tissue intact, including small epithelialized islands of vital tissue. The procedure was without pain and adverse events. Scanning electron microscopic analyses identified the majority of the removed debris tightly packed within the monofilament texture. A surgeon who blindly assessed pictures taken before and after the debridement categorized all except one wound without the need for surgical debridement and ranked all the debridement results with the new debrider as 'very good' (best category). This formulates the basic concept that the new debrider-based technology is easy, fast, highly efficient, well tolerated and cost effective.

Topical antimicrobial agents for the treatment of chronic wounds.

PubMed

Ousey, Karen; McIntosh, Caroline

2009-09-01

Chronic wounds are commonly observed in acute and community settings. The management of chronic wounds represents a significant proportion of health-care resources and makes up a substantial amount of contact time with community-based nurses spending approximately 25% to 50% of their time treating wounds. Chronic wounds often exhibit increased bacterial burden that can negatively impact upon patients, reduce their quality of life and substantially increase treatment costs for health care providers. Antibiotic resistance has become a major medical and public health problem, and interest has been generated in the use of topical therapies to manage wound infection. This article presents an overview of the historical use of honey, silver and iodine for the treatment of infected wounds progressing through to modern day use and the current evidence base for the use of these antimicrobial agents in the management of infected wounds.

Honey: a reservoir for microorganisms and an inhibitory agent for microbes.

Honey is an ancient remedy for the treatment of infected wounds, which has recently been 'rediscovered' by the medical profession. The use to which honey is put in medical care is increasing daily with many authors pointing out its importance and role in wound care. There have been reports that honey contains many microorganisms including bacteria and fungi. The aim of this paper is to highlight the various uses, organisms commonly found in honey, how the organisms arrived in the honey and their effects on wounds and wound care. Would the presence of these organisms not constitute a limiting factor to the use of honey in wound management? This is what this review aims to answer. A literature search was done on honey using pubmed, google, local books and journals. Relevant journals were extracted and discussed with emphasis on the antimicrobial properties as well as microbial content of honey and the implications of these. The production of honey as well as the storing process account for the presence of microorganisims. Most of these organisms are said to be in inactive forms as they can hardly survive in honey because of its several properties including hygroscopicity, hyperosmolarity, acidity, peroxide content, antibiotic activities etc. However there is a need for caution in the use of honey in wound management. We suggest that wounds to be treated with honey should be investigated i.e with a swab for the microorganisms present on the wound and their sensitivity to the honey before commencing honey treatment. This will help in carefully selecting wounds that might do well with honey treatment not withstanding other properties of honey that aid wound healing.

Diabetic foot ulcers (DFUs) are a major burden on the health-care system. The purpose of this study is to investigate factors affecting the healing rate of DFU in a university wound care center. Records of DFU patients treated between July 2013 and February 2015 were reviewed. Demographics, comorbidities, wound characteristics, and treatment modalities including offloading, hyperbaric oxygen treatment, total contact casting, and bioengineered skin were investigated. All patients underwent weekly debridement regardless of treatment modality. A total of 114 patients ages 18 to 98 comprised the study population. Total contact casting was the only treatment associated with increased healing (P = 0.02). Smoking (P = 0.004) and deep vein thrombosis history (P = 0.001) significantly decreased the likelihood of wound healing. Patients with past vascular event trended toward longer healing times (P = 0.07). Total contact casting in combination with weekly wound debridement showed benefit in DFU wound healing, whereas patients with a history of deep vein thrombosis and smoking were less likely to heal.

Design Considerations for Post-Acute Care mHealth: Patient Perspectives.

Sanger, Patrick; Hartzler, Andrea; Lober, William B; Evans, Heather L; Pratt, Wanda

2014-01-01

Many current mobile health applications ("apps") and most previous research have been directed at management of chronic illnesses. However, little is known about patient preferences and design considerations for apps intended to help in a post-acute setting. Our team is developing an mHealth platform to engage patients in wound tracking to identify and manage surgical site infections (SSI) after hospital discharge. Post-discharge SSIs are a major source of morbidity and expense, and occur at a critical care transition when patients are physically and emotionally stressed. Through interviews with surgical patients who experienced SSI, we derived design considerations for such a post-acute care app. Key design qualities include: meeting basic accessibility, usability and security needs; encouraging patient-centeredness; facilitating better, more predictable communication; and supporting personalized management by providers. We illustrate our application of these guiding design considerations and propose a new framework for mHealth design based on illness duration and intensity.

Burns and the associated wound care procedures can be extremely painful and anxiety-provoking for children. Burn injured children and adolescents are therefore at greater risk of experiencing a range of psychological reactions, in particular posttraumatic stress disorder, which can persist for months to years after the injury. Non-pharmacological intervention is critical for comprehensive pain and anxiety management and is used alongside pharmacological analgesia and anxiolysis. However, effective non-pharmacological pain and anxiety management during pediatric burn procedures is an area still needing improvement. Medical hypnosis has received support as a technique for effectively decreasing pain and anxiety levels in adults undergoing burn wound care and in children during a variety of painful medical procedures (e.g., bone marrow aspirations, lumbar punctures, voiding cystourethrograms, and post-surgical pain). Pain reduction during burn wound care procedures is linked with improved wound healing rates. To date, no randomized controlled trials have investigated the use of medical hypnosis in pediatric burn populations. Therefore this study aims to determine if medical hypnosis decreases pain, anxiety, and biological stress markers during wound care procedures; improves wound healing times; and decreases rates of traumatic stress reactions in pediatric burn patients. This is a single-center, superiority, parallel-group, prospective randomized controlled trial. Children (4 to 16 years, inclusive) with acute burn injuries presenting for their first dressing application or change are randomly assigned to either the (1) intervention group (medical hypnosis) or (2) control group (standard care). A minimum of 33 participants are recruited for each treatment group. Repeated measures of pain, anxiety, stress, and wound healing are taken at every dressing change until ≥95 % wound re-epithelialization. Further data collection assesses impact on posttraumatic stress symptomatology, speed of wound healing, and parent perception of how easy the dressing change is for their child. Study results will elucidate whether the disease process can be changed by using medical hypnosis with children to decrease pain, anxiety, and stress in the context of acute burn wounds.

Experience of organization of the surgical care in the military hospital to 438 wounded in extremities during armed conflict in Republic of Chechnya is generalized. Maximum reduction of stages of medical evacuation of the wounded in extremities, approaching of the qualified and urgent specialized surgical care directly to the region of battle actions, use of opportunities for it one-moment rendering corresponded to principles of the modern military-medical doctrine. Due to realization of the requirements of the doctrine life of many wounded ++ was saved, terms of treatment, medical and social rehabilitation are reduced. Besides lethality, treatment cost and numbers of transferring to the reserve from the Armed Forces were reduced.

abstract Wound healing is a complex physiological process including overlapping phases (hemostatic/inflammatory, proliferating and remodeling phases). Every alteration in this mechanism might lead to pathological conditions of different medical relevance. Treatments for chronic non-healing wounds are expensive because reiterative treatments are needed. Regenerative medicine and in particular mesenchymal stem cells approach is emerging as new potential clinical application in wound healing. In the past decades, advance in the understanding of molecular mechanisms underlying wound healing process has led to extensive topical administration of growth factors as part of wound care. Currently, no definitive treatment is available and the research on optimal wound care depends upon the efficacy and cost-benefit of emerging therapies. Here we provide an overview on the novel approaches through stem cell therapy to improve cutaneous wound healing, with a focus on diabetic wounds and Systemic Sclerosis-associated ulcers, which are particularly challenging. Current and future treatment approaches are discussed with an emphasis on recent advances. PMID:26652928

The Effect of Oral Medication on Wound Healing.

2017-03-01

The purpose of this learning activity is to provide information about the effects of oral medications on wound healing. This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and nurses with an interest in skin and wound care. After participating in this educational activity, the participant should be better able to:1. Identify oral medications that aid in wound healing.2. Recognize oral medications that interfere with wound healing. Given the accelerated medical discoveries of recent decades, there is a surprising lack of oral medications that directly improve wound healing. Of the oral medications available, most target ancillary aspects of wound care such as pain management, infection mitigation, and nutrition. This article describes oral pharmacologic agents intended to build new tissue and aid in wound healing, as well as an introduction to oral medications that interfere with wound healing. This review will not discuss the pharmacology of pain management or treatment of infection, nor will it address nutritional supplements.

Background Traditionally, chronic wound infection is diagnosed by visual inspection under white light and microbiological sampling, which are subjective and suboptimal, respectively, thereby delaying diagnosis and treatment. To address this, we developed a novel handheld, fluorescence imaging device (PRODIGI) that enables non-contact, real-time, high-resolution visualization and differentiation of key pathogenic bacteria through their endogenous autofluorescence, as well as connective tissues in wounds. Methods and Findings This was a two-part Phase I, single center, non-randomized trial of chronic wound patients (male and female, ≥18 years; UHN REB #09-0015-A for part 1; UHN REB #12-5003 for part 2; clinicaltrials.gov Identifier: NCT01378728 for part 1 and NCT01651845 for part 2). Part 1 (28 patients; 54% diabetic foot ulcers, 46% non-diabetic wounds) established the feasibility of autofluorescence imaging to accurately guide wound sampling, validated against blinded, gold standard swab-based microbiology. Part 2 (12 patients; 83.3% diabetic foot ulcers, 16.7% non-diabetic wounds) established the feasibility of autofluorescence imaging to guide wound treatment and quantitatively assess treatment response. We showed that PRODIGI can be used to guide and improve microbiological sampling and debridement of wounds in situ, enabling diagnosis, treatment guidance and response assessment in patients with chronic wounds. PRODIGI is safe, easy to use and integrates into the clinical workflow. Clinically significant bacterial burden can be detected in seconds, quantitatively tracked over days-to-months and their biodistribution mapped within the wound bed, periphery, and other remote areas. Conclusions PRODIGI represents a technological advancement in wound sampling and treatment guidance for clinical wound care at the point-of-care.

Dermal tissue loss in patients affected by critical limb ischemia represents a serious wound-healing problem, with high morbidity, prolonged hospital stay, and high patient care costs. Treatment of ischemic foot lesions requires limb revascularization by endovascular or open surgical intervention and individualized patient-specific wound care, including antibiotic therapy; devitalized/infected wound debridement; and advanced wound dressing. In selected patients, spinal cord stimulation, vacuum-assisted closure therapy, and bioengineered tissue or skin substitutes and growth factors have been shown to improve wound healing. In this study, we present our preliminary results on topical application of autologous platelet-rich plasma to enhance the process of wound healing after revascularization of lower limbs in patients affected by critical limb ischemia.

Several patients present to wound healing specialists seeking a natural or alternative medical approach to their wounds. The purpose of this prospective, case-cohort study of 10 patients was to evaluate the use of Oceanzyme Wound Care Spray (Ocean Aid, Inc, Boynton Beach, FL) in improving healing in diabetic foot ulcers during a 12-week period. This product contains water purified by reverse osmosis, coral reef sea salt, lysozyme, and sodium benzoate. The primary endpoint was wound closure, and secondary endpoints were infection rate and wound area reduction. Overall, 2 patients healed, 2 withdrew, and the remaining 6 had an average of 73% reduction in wound area. While more study is needed, the use of this sea salt-based spray may provide a viable alternative for patients seeking a natural therapy for their wound care.

Wound healing is a primary survival mechanism that is largely taken for granted. The literature includes relatively little information about disturbed wound healing, and there is no acceptable classification describing wound healing process in the oral region. Wound healing comprises a sequence of complex biological processes. All tissues follow an essentially identical pattern to complete the healing process with minimal scar formation. The oral cavity is a remarkable environment in which wound healing occurs in warm oral fluid containing millions of microorganisms. The present review provides a basic overview of the wound healing process and with a discussion of the local and general factors that play roles in achieving efficient would healing. Results of oral cavity wound healing can vary from a clinically healed wound without scar formation and with histologically normal connective tissue under epithelial cells to extreme forms of trismus caused by fibrosis. Many local and general factors affect oral wound healing, and an improved understanding of these factors will help to address issues that lead to poor oral wound healing. PMID:27853435

Our purpose was to compare healing characteristics of diabetic foot ulcers treated with dehydrated human amniotic membrane allografts (EpiFix®, MiMedx, Kennesaw, GA) versus standard of care. An IRB-approved, prospective, randomised, single-centre clinical trial was performed. Included were patients with a diabetic foot ulcer of at least 4-week duration without infection having adequate arterial perfusion. Patients were randomised to receive standard care alone or standard care with the addition of EpiFix. Wound size reduction and rates of complete healing after 4 and 6 weeks were evaluated. In the standard care group (n = 12) and the EpiFix group (n = 13) wounds reduced in size by a mean of 32·0% ± 47·3% versus 97·1% ± 7·0% (P < 0·001) after 4 weeks, whereas at 6 weeks wounds were reduced by −1·8% ± 70·3% versus 98·4% ± 5·8% (P < 0·001), standard care versus EpiFix, respectively. After 4 and 6 weeks of treatment the overall healing rate with application of EpiFix was shown to be 77% and 92%, respectively, whereas standard care healed 0% and 8% of the wounds (P < 0·001), respectively. Patients treated with EpiFix achieved superior healing rates over standard treatment alone. These results show that using EpiFix in addition to standard care is efficacious for wound healing.

The use of natural products in compounded wound care formulas is an exciting avenue to pursue for compounding pharmacists since these natural products may contain compounds that promote healing on their own. The use of these natural extracts as an alternative therapy for wound care may also provide several benefits, such as decreased inflammation, infection, side effects, and treatment costs. Thus far, several studies have demonstrated antimicrobial activity for various natural product extracts, including green propolis and meadowsweet. The antimicrobial properties of these extracts make them particularly interesting for wound care because the healing process is significantly delayed by bacterial infection and colonization at the site of injury. Therefore, to further investigate the antimicrobial properties of green propolis and meadowsweet extracts, we performed minimum inhibitory concentration and minimum bactericidal concentration assays against Staphylococcus aureus, a microorganism known to cause wound infections. The antimicrobial activity of green propolis and meadowsweet extracts was tested in vitro against a standard strain of Staphylococcus aureus in brain heart infusion broth and Mueller-Hinton agar plates. Green propolis extract demonstrated antimicrobial activity against Staphylococcus aureus with a minimum inhibitory concentration of 1.25 mg/mL and a minimum bactericidal concentration of 1.25 mg/mL. In contrast, meadowsweet extract failed to inhibit Staphylococcus aureus growth at the highest concentration tested (30 mg/mL). Green propolis was more effective than meadowsweet extract at inhibiting the growth of Staphylococcus aureus, suggesting that the addition of green propolis extract in wound care formulas might be more beneficial for the treatment of wounds. Therefore, we propose that green propolis extract is a promising natural product for wound care formulations. Copyright© by International Journal of Pharmaceutical Compounding, Inc.

Cost-effectiveness in the contemporary management of critical limb ischemia with tissue loss.

PubMed

Barshes, Neal R; Chambers, James D; Cohen, Joshua; Belkin, Michael

2012-10-01

The care of patients with critical limb ischemia (CLI) and tissue loss is notoriously challenging and expensive. We evaluated the cost-effectiveness of various management strategies to identify those that would optimize value to patients. A probabilistic Markov model was used to create a detailed simulation of patient-oriented outcomes, including clinical events, wound healing, functional outcomes, and quality-adjusted life-years (QALYs) after various management strategies in a CLI patient cohort during a 10-year period. Direct and indirect cost estimates for these strategies were obtained using transition cost-accounting methodology. Incremental cost-effectiveness ratios (ICERs), in 2009 U.S. dollars per QALYs, were calculated compared with the most conservative management strategy of local wound care with amputation as needed. With an ICER of $47,735/QALY, an initial surgical bypass with subsequent endovascular revision(s) as needed was the most cost-effective alternative to local wound care alone. Endovascular-first management strategies achieved comparable clinical outcomes but at higher cost (ICERs ≥$101,702/QALY); however, endovascular management did become cost-effective when the initial foot wound closure rate was >37% or when procedural costs were decreased by >42%. Primary amputation was dominated (less effectiveness and more costly than wound care alone). Contemporary clinical effectiveness and cost estimates show an initial surgical bypass is the most cost-effective alternative to local wound care alone for CLI with tissue loss and can be supported even in a cost-averse health care environment.

Both nationally and internationally concerns have been expressed over the adequacy of preparation of undergraduate nurses for the clinical skill of wound care. This project describes the educational evaluation of a series of Reusable Learning Objects (RLOs) as a blended learning approach to facilitate undergraduate nursing students learning of wound care for competence development. Constructivism Learning Theory and Cognitive Theory of Multimedia Learning informed the design of the RLOs, promoting active learner approaches. Clinically based case studies and visual data from two large university teaching hospitals provided the authentic learning materials required. Interactive exercises and formative feedback were incorporated into the educational resource. Evaluation of student perceived learning gains in terms of knowledge, ability and attitudes were measured using a quantitative pre and posttest Wound Care Competency Outcomes Questionnaire. The RLO CETL Questionnaire was used to identify perceived learning enablers. Statistical and deductive thematic analyses inform the findings. Students (n=192) reported that their ability to meet the competency outcomes for wound care had increased significantly after engaging with the RLOs. Students rated the RLOs highly across all categories of perceived usefulness, impact, access and integration. These findings provide evidence that the use of RLOs for both knowledge-based and performance-based learning is effective. RLOs when designed using clinically real case scenarios reflect the true complexities of wound care and offer innovative interventions in nursing curricula. Copyright © 2017 Elsevier Ltd.

2007-01-01

Lower extremity complications in persons with diabetes have become an increasingly significant public health concern in both the developed and developing world. These complications, beginning with neuropathy and subsequent diabetic foot wounds frequently lead to infection and lower extremity amputation even in the absence of critical limb ischemia. In order to diminish the detrimental consequences associated with diabetic foot ulcers, a common-sense-based treatment approach must be implemented. Many of the etiological factors contributing to the formation of diabetic foot ulceration may be identified using simple, inexpensive equipment in a clinical setting. Prevention of diabetic foot ulcers can be accomplished in a primary care setting with a brief history and screening for loss of protective sensation via the Semmes-Weinstein monofilament. Specialist clinics may quantify neuropathy, plantar foot pressure, and assess vascular status with Doppler ultrasound and ankle-brachial blood pressure indices. These measurements, in conjunction with other findings from the history and physical examination, may enable clinicians to stratify patients based on risk and help determine the type of intervention. Other effective clinical interventions may include patient education, optimizing glycemic control, smoking cessation, and diligent foot care. Recent technological advanced combined with better understanding of the wound healing process have resulted in a myriad of advanced wound healing modalities in the treatment of diabetic foot ulcers. However, it is imperative to remember the fundamental basics in the healing of diabetic foot ulcers: adequate perfusion, debridement, infection control, and pressure mitigation. Early recognition of the etiological factors along with prompt management of diabetic foot ulcers is essential for successful outcome.

To describe the presence or absence of key components of hospital pressure ulcer (PU) prevention programs in 6 acute care hospitals. Multisite comparative case study. Using purposeful selection based on PU rates (high vs low) and hospital size, 6 hospitals within the Veterans Health Administration health care system were invited to participate. Key informant interviews (n = 48) were conducted in each of the 6 participating hospitals among individuals playing key roles in PU prevention: senior nursing leadership (n = 9), nurse manager (n = 7), wound care specialist (n = 6), frontline RNs (n = 26). Qualitative data were collected during face-to-face, semistructured interviews. Interview protocols were tailored to each interviewee's role with a core set of common questions covering 3 major content areas: (1) practice environment (eg, policies and wound care specialists), (2) current prevention practices (eg, conduct of PU risk assessment and skin inspection), and (3) barriers to PU prevention. We conducted structured coding of 5 key components of PU prevention programs and cross-case analysis to identify patterns in operationalization and implementation of program components across hospitals based on facility size and PU rates (low vs high). All hospitals had implemented all PU prevention program components. Component operationalization varied considerably across hospitals. Wound care specialists were integral to the operationalization of the 4 other program components examined; however, staffing levels and work assignments of wound care specialists varied widely. Patterns emerged among hospitals with low and high PU rates with respect to wound care specialist staffing, data monitoring, and staff education. We found hospital-level variations in PU prevention programs. Wound care specialist staffing may represent a potential point of leverage in achieving other PU program components, particularly performance monitoring and staff education.

There are a wide variety of dressing techniques and materials available for management of both acute wounds and chronic non-healing wounds. The primary objective in both the cases is to achieve a healed closed wound. However, in a chronic wound the dressing may be required for preparing the wound bed for further operative procedures such as skin grafting. An ideal dressing material should not only accelerate wound healing but also reduce loss of protein, electrolytes and fluid from the wound, and help to minimize pain and infection. The present dictum is to promote the concept of moist wound healing. This is in sharp contrast to the earlier practice of exposure method of wound management wherein the wound was allowed to dry. It can be quite a challenge for any physician to choose an appropriate dressing material when faced with a wound. Since wound care is undergoing a constant change and new products are being introduced into the market frequently, one needs to keep abreast of their effect on wound healing. This article emphasizes on the importance of assessment of the wound bed, the amount of drainage, depth of damage, presence of infection and location of wound. These characteristics will help any clinician decide on which product to use and where,in order to get optimal wound healing. However, there are no ‘magical dressings’. Dressings are one important aspect that promotes wound healing apart from treating the underlying cause and other supportive measures like nutrition and systemic antibiotics need to be given equal attention.

The care of traumatic wounds has evolved over hundreds of years, largely as a result of armed conflicts. The lessons learned during World War I in the treatment of extensive soft-tissue injuries proved invaluable in reducing infection and preventing loss of limb and life. Foremost among these was the use of debridement. This report reviews the development of debridement as standard treatment of war wounds and highlights the surgeon largely responsible for its resurgence during one of this century's saddest chapters. Before World War I, the care of wounds consisted of minimal exploration and liberal use of then-new antiseptics. For limited injuries, this approach appeared adequate. World War I saw the introduction of devastating weapons that produced injuries that caused extensive devitalization of tissue. Standard treatment of these patients proved woefully inadequate to prevent life-threatening infections. This is a historical review of the conditions that occurred during World War I that prompted a change in wound management. One of those responsible for this change was the Belgian surgeon Antoine Depage. His life and contributions to the care of war wounds are profiled. Depage reintroduced the discarded French practice of wound incision and exploration (debridement) and combined it with excision of devitalized tissue. Through the use of debridement, excision, and delayed wound closure based on bacteriologic survey, Depage was able to reduce the incidence of infectious complications of soft-tissue injuries, particularly those involving fractures. Through his experiences in the Great War, Antoine Depage was able to formulate a treatment plan for wounds of war. All such injuries were assumed to be contaminated and, as such, they required early and careful debridement. Depage thought that wound closure should often be delayed and based his decision to close on the bacteriologic status of the wound. To him, we owe our current management of traumatic wounds.

Students in Biomaterials BBE3102 at Makerere University in Kampala, Uganda were assigned semester long group projects in the first semester of the 2014-15 academic year to determine the biomaterials type and usage in Mulago National Referral Hospital, which is emblematic of large public hospitals across East Africa. Information gathering was conducted through student interviews with Mulago physicians because there were no archival records. The students divided themselves into seven project groups covering biomaterials use in the areas of wound closure, dental and oral surgery, cardiology, burn care, bone repair, ophthalmology and total joint replacement. As in the developed world, the majority of biomaterials used in Mulago are basic wound closure materials, dental materials, and bone fixation materials, all of which are comparatively inexpensive, easy to store, and readily available from either the government or local suppliers; however, there were significant issues with the implant supply chain, affordability, and patient compliance and follow-up in cases where specialty expertise and expensive implants were employed. © 2015 Wiley Periodicals, Inc.

To determine the opinions of healthcare clinicians in the Philippines regarding the 2016 National Pressure Ulcer Advisory Panel (NPUAP) terminology changes and revised staging definitions. A survey methodology was used in Manila, Philippines. Convenience samples of healthcare clinicians of varying disciplines and employment settings were invited to participate in this research. A survey was administered at key intervals regarding the revised NPUAP terminology changes and revised staging definitions. The survey was administered before and after an interactive, basic 2-day wound course was conducted. Results revealed strong support for the 2016 NPUAP terminology change from pressure ulcer to pressure injury and the revised staging definitions. Since the NPUAP changed its terminology and revised the staging definitions, the wound care community has been responding to those changes. Because pressure injuries are a global health concern, the opinions of clinicians outside the United States are equally valuable. The healthcare clinicians in the Philippines surveyed appear to embrace the new terminology changes and revised staging definitions put forth by the NPUAP.

Based on its intrinsic mass and velocity, a bullet has an upper limit of wounding potential. Actual wound severity is a function of the bullet construction and trajectory, as well as the properties of the tissues traversed. Interpreting physicians must evaluate the bullet trajectory and describe patterns of injury resulting from the effect of energy transfer from the projectile into living tissue. A basic understanding of firearms, projectiles, and wound ballistics can help the interpreting physicians in conceptualizing these injuries and interpreting these cases.

Chronic wounds, including pressure ulcers, compromise the health of 6.5 million Americans and pose an annual estimated burden of $25 billion to the U.S. health care system. When treating chronic wounds, clinicians must use meticulous documentation to determine wound severity and to monitor healing progress over time. Yet, current wound documentation practices using digital photography are often cumbersome and labor intensive. The process of transferring photos into Electronic Medical Records (EMRs) requires many steps and can take several days. Newer smartphone and tablet-based solutions, such as Epic Haiku, have reduced EMR upload time. However, issues still exist involving patient positioning, image-capture technique, and patient identification. In this paper, we present the development and assessment of the SnapCap System for chronic wound photography. Through leveraging the sensor capabilities of Google Glass, SnapCap enables hands-free digital image capture, and the tagging and transfer of images to a patient’s EMR. In a pilot study with wound care nurses at Stanford Hospital (n=16), we (i) examined feature preferences for hands-free digital image capture and documentation, and (ii) compared SnapCap to the state of the art in digital wound care photography, the Epic Haiku application. We used the Wilcoxon Signed-ranks test to evaluate differences in mean ranks between preference options. Preferred hands-free navigation features include barcode scanning for patient identification, Z(15) = -3.873, p < 0.001, r = 0.71, and double-blinking to take photographs, Z(13) = -3.606, p < 0.001, r = 0.71. In the comparison between SnapCap and Epic Haiku, the SnapCap System was preferred for sterile image-capture technique, Z(16) = -3.873, p < 0.001, r = 0.68. Responses were divided with respect to image quality and overall ease of use. The study’s results have contributed to the future implementation of new features aimed at enhancing mobile hands-free digital photography for chronic wound care. PMID:25902061

Nurses in the field of wound care are increasingly being courted by the wound industry. A survey regarding nurses' perceptions and participation in pharmaceutical marketing was conducted. Based on existing instruments, a standardized questionnaire (39 items, 5-point Likert scale) was developed. It was sent electronically and by mail to all nursing members of the Austrian Society for Vascular Care (ÖGvP), the German Wound Healing Society (DGfW e. V.) and the Swiss Association for Wound Care (SAfW). 178 nurses participated in the survey (75 % women; aged 27 - 70 years [median 45], 0 - 40 years [median 9] practice in the area of the wound care). Only about one fourth of the respondents (23,0 %) did not participate in pharmaceutical marketing last year. Generally small gifts were more frequently received than expensive gifts. Most of the nurses valued inexpensive gifts, educational gifts and gifts with patient benefit as appropriate. The majority of respondents consider themselves as less influenceable in decision making, compared to physicians. The behavior and attitude of nurses are ambivalent. The occurrence of conflict of interest is partly justified by perceived patient benefit. Lack of knowledge about the topic and social desirability could be the cause of an uncritical attitude. For a more critical approach education and ethical standards are necessary.

The 2010 earthquake in Port-au-Prince, Haiti, highlighted the need for wound care in resource-poor countries. Subsequently, the University of Miami in Florida established one of the first interprofessional wound care centers located at Bernard Mevs Hospital in the central portion of Port-au-Prince, caring for patients with acute and chronic wounds. In 2012, the authors used a novel epidermal harvesting system (CelluTome Epidermal Harvesting System; Kinetic Concepts Inc, San Antonio, Texas) to harvest epithelium to be grafted on 7 patients at the Mevs Hospital with longstanding wounds. Epidermal microblisters were obtained from each patient's thigh using the CelluTome Epidermal Harvesting System. After 35 minutes, microblisters were raised using the device harvester, and an adhesive dressing was inserted into the harvester for transfer to the wound site. In patients with lower-extremity wounds, a 2-layer compression dressing was placed over epidermal grafts. Six of the 7 wounds improved or achieved complete closure in 4 weeks. One of the patients with a 2-year-old thigh wound failed to demonstrate improvement; this may have been secondary to an inability to adequately secure the graft. All donor sites healed without any visible scarring. The authors were able to conclude that epidermal grafting may represent a viable reconstructive option for patients in resource-poor countries.

Chronic wounds are a drain on resources both for the patient and health institution. Management of chronic wounds based on evidence-based practice requires baseline data for adequate planning. This study was carried out to determine the point prevalence of chronic wounds in a tertiary hospital (University College Hospital, Ibadan, Nigeria) and utilize this information for subsequent wound care planning. The study was carried out within a 1-month period and included all patients seen in the hospital with chronic wounds. The data obtained was entered into a designed form and was subsequently analyzed. There were 48 patients with 78 wounds representing approximately 11% of patients seen in the Department of Plastic, Reconstructive, and Aesthetic Surgery each month. Their ages ranged from 3 months to 80 years; the median age was 48 years. The male to female ratio was 1.6 to 1. The duration of the wounds ranged from 6 weeks to 780 weeks; the median duration of the wounds was 10 weeks. The area of the wounds ranged from 1 cm(2) -1,248 cm(2) (median 24 cm(2)). The most common chronic wounds were diabetic wounds, followed by pressure ulcers, postinfection ulcers, posttraumatic ulcers, burn wounds, malignant ulcers, and venous ulcers. The point prevalence data serves as a basis for wound care planning. This, in turn, should result in improved wound management grounded in evidence-based practices.

Pre-tibial lacerations are complex wounds affecting a primarily aged population, with poor healing and a potentially significant impact on social well-being. Management of these wounds has changed little in 20 years, despite significant advances in wound care. A retrospective observational study was undertaken to observe current wound care practice and to assess the effect of various medical factors on wound healing time on 24 elderly patients throughout their wound journey. Wound length was found to be substantively and significantly associated with wound healing time, with a reduction in instantaneous healing rate of about 30% for every increase of 1 cm in wound length. Hence, longer wounds are associated with longer wound healing times. Prescription of several categories of drugs, including those for ischaemic heart disease (IHD), hypertension, respiratory disease or asthma; and the age of the patient were not significantly associated with wound healing times, although substantive significance could be inferred in the case of prescription for IHD and asthma. Despite the small sample size, this study identified a clear association between healing and length of wound. Neither the comorbidities nor prescriptions explored showed any significant association although some seem to be more prevalent in this patient group. The study also highlighted other issues that require further exploration including the social and economic impact of these wounds. © 2011 The Authors. © 2011 Blackwell Publishing Ltd and Medicalhelplines.com Inc.

To establish the prevalence of wounds and their management in a community care setting. A multi-site, census point prevalence wound survey was conducted in the following areas: intellectual disability, psychiatry, GP practices, prisons, long-term care private nursing homes, long-term care, public nursing homes and the community/public health (district) nursing services on one randomly selected day. Acute services were excluded. Formal ethical approval was obtained. Data were collected using a pre-piloted questionnaire. Education was provided to nurses recording the tool (n=148). Descriptive statistical analysis was performed. A 97.2% response rate yielded a crude prevalence rate of 15.6% for wounds across nursing disciplines (290/1,854 total census) and 0.2% for the community area (290/133,562 population statistics for the study area). Crude point prevalence ranged from 2.7% in the prison services (7/262 total prison population surveyed) to 33.5% in the intellectual disability services (72/215 total intellectual disability population surveyed). The most frequent wounds recorded were pressure ulcers (crude point prevalence 4%, 76/1,854 total census; excluding category l crude point prevalence was 2.6%, 49/1,854 total census), leg ulcers (crude point prevalence 2.9%, 55/1,854 total census), self-inflicted superficial abrasions (crude point prevalence 2.2%, 41/1,854 total census) and surgical wounds (crude point prevalence 1.7%, 32/1,854 total census). These results support previous international research in that they identify a high prevalence of wounds in the community. The true community prevalence of wounds is arguably much higher, as this study identified only wounds known to the nursing services and excluded acute settings and was conducted on one day.

Protein-calorie malnutrition and involuntary weight loss: the role of aggressive nutritional intervention in wound healing.

PubMed

Himes, D

1999-03-01

Protein-calorie malnutrition and involuntary weight loss continue to be prevalent among hospitalized and long-term care patients, particularly the elderly. Studies on nutritional intervention have established a correlation between nutritional status, body weight, and rate of wound healing. Nutritional intervention, however, must be provided early enough to prevent a catabolic-induced decline in lean muscle mass, which can further impair wound healing. Chronic, nonhealing wounds are particularly difficult to treat and contribute to significant morbidity, mortality, and hospitalizations. More aggressive nutritional management and a greater understanding of the role of nutrition and weight gain in wound healing can result in more effective patient care. This article discusses the role of protein-calorie malnutrition and involuntary weight loss in hindering the wound-healing process, and the need to establish an optimal anabolic environment for weight gain and improved wound healing.

Postsurgical wound care has a great impact on patients' prognosis. It often takes few days, even few weeks, for the wound to stabilize, which incurs a great cost of health care and nursing resources. To assess the wound condition and diagnosis, it is important to segment out the wound region for further analysis. However, the scenario of this strategy often consists of complicated background and noise. In this study, we propose a wound segmentation algorithm based on Canny edge detector and genetic algorithm with an unsupervised evaluation function. The results were evaluated by the 112 clinical images, and 94.3% of images were correctly segmented. The judgment was based on the evaluation of experimented medical doctors. This capability to extract complete wound regions, makes it possible to conduct further image analysis such as intelligent recovery evaluation and automatic infection requirements.

To investigate the efficacy of basic fibroblast growth factor (bFGF) combined with topical oxygen therapy for deep II degree burn wounds, by comparing the effects of bFGF combined with topical oxygen therapy and bFGF with routine therapy. From February 2004 to July 2009, 85 patients with deep II degree burn wounds (117 wounds) were enrolled and divided into 4 groups randomly according to different treatments. There was no significant difference in sex, age, disease course, wound size, and wound treatment size among 4 groups (P > 0.05). In group A, 18 patients (28 wounds) were treated routinely; in group B, 23 patients (30 wounds) were treated with routine methods and topical oxygen therapy; in group C, 19 patients (25 wounds) were treated with routine methods and bFGF therapy; and in group D, 25 patients (34 wounds) were treated with routine methods and bFGF/topical oxygen therapy. Topical oxygen therapy was administered to the wound for 90 minutes per day for 3 weeks. The bFGF therapy was applied everyday (150 U/cm2) for 3 weeks. All cases were followed up 6-12 months (9 months on average). The wound healing times in groups A, B, C, and D were (27.3 +/- 6.6), (24.2 +/- 5.8), (22.2 +/- 6.8), and (18.2 +/- 4.8) days, respectively; showing significant difference between group A and group D (P < 0.05). The wound healing rates in groups A, B, C, and D were 67.8% +/- 12.1%, 85.1% +/- 7.5%, 89.2% +/- 8.3%, and 96.1% +/- 5.6%, respectively; showing significant differences between group A and groups B, C, D (P < 0.05). The therapic effective rates in groups A, B, C, and D were 75%, 90%, 92%, and 100%, respectively; showing significant difference between group A and group D (P < 0.05). The Vancouver scar scale scoring of group D 6 months after treatment was better than that of group A (P < 0.05). The bFGF combined with topical oxygen therapy can enhance deep II degree burn wound healing. Furthermore, the therapy method is simple and convenient.

Using Light to Treat Mucositis and Help Wounds Heal

A continuing program of research and development is focusing on the use of controlled illumination by light-emitting diodes (LEDs) to treat mucositis and to accelerate healing of wounds. The basic idea is to illuminate the affected area of a patient with light of an intensity, duration, and wavelength (or combination of wavelengths) chosen to produce a therapeutic effect while generating only a minimal amount of heat. This method of treatment was originally intended for treating the mucositis that is a common complication of chemotherapy and radiation therapy for cancer. It is now also under consideration as a means to accelerate the healing of wounds and possibly also to treat exposure to chemical and radioactive warfare agents. Radiation therapy and many chemotherapeutic drugs often damage the mucosal linings of the mouth and gastrointestinal tract, leading to mouth ulcers (oral mucositis), nausea, and diarrhea. Hyperbaric-oxygen therapy is currently the standard of care for ischemic, hypoxic, infected, and otherwise slowlyhealing problem wounds, including those of oral mucositis. Hyperbaric-oxygen therapy increases such cellular activities as collagen production and angiogenesis, leading to an increased rate of healing. Biostimulation by use of laser light has also been found to be effective in treating mucositis. For hyperbaricoxygen treatment, a patient must remain inside a hyperbaric chamber for an extended time. Laser treatment is limited by laser-wavelength capabilities and by narrowness of laser beams, and usually entails the generation of significant amounts of heat.

Mortality following shooting is related to time to provision of initial and definitive care. An understanding of the wounding pattern, opportunities for rescue, and incidence of possibly preventable death is needed to achieve the goal of zero preventable deaths following trauma. A retrospective study of autopsy reports for all victims involved in the Pulse Nightclub Shooting was performed. The site of injury, probable site of fatal injury, and presence of potentially survivable injury (defined as survival if prehospital care is provided within 10 minutes and trauma center care within 60 minutes of injury) was determined independently by each author. Wounds were considered fatal if they involved penetration of the heart, injury to any non-extremity major blood vessel, or bihemispheric, mid-brain, or brainstem injury. There were an average of 6.9 wounds per patient. Ninety percent had a gunshot to an extremity, 78% to the chest, 47% to the abdomen/pelvis, and 39% to the head. Sixteen patients (32%) had potentially survivable wounds, 9 (56%) of whom had torso injuries. Four patients had extremity injuries, 2 involved femoral vessels and 2 involved the axilla. No patients had documented tourniquets or wound packing prior to arrival to the hospital. One patient had an isolated C6 injury and 2 victims had unihemispheric gunshots to the head. A comprehensive strategy starting with civilian providers to provide care at the point of wounding along with a coordinated public safety approach to rapidly evacuate the wounded may increase survival in future events.

Abstract Management of chronic wounds remains unsatisfactory in terms of treatment cost and time required for complete wound closure (CWC). This study aimed to calculate the healing rates, estimated cost, and time required for CWC in wounds; compare estimated wound care costs between healing and nonhealing wounds; and compare cost effectiveness between venous leg ulcer (VLU) and non-VLU. This was a retrospective cohort study performed at a physical therapy (PT) wound care clinic. Deidentified patient data in the electronic medical database from September 10, 2012 to January 23, 2015 were extracted. Among 159 included patients with wounds, 119 (74.84%) patients were healed with CWC. The included patients were treated for 109.70 ± 95.70 days, 29.71 ± 25.66 visits, and at the costs per treatment episode of $1629.65 ± 1378.82 per reimbursement rate and $2711.42 ± 2356.81 per breakeven rate. For patients with CWC (healing group), the treatment duration was 98.01 ± 76.12 days with the time for CWC as 72.45 ± 64.21 days; the cost per treatment episode was $1327.24 ± 1143.53 for reimbursement rate and $2492.58 ± 2106.88 for breakeven cost. For patients with nonhealing wounds, treatment duration was found to be longer with costs significantly higher (P < 0.01 for all). In the healing group, no differences were found between VLU and non-VLU in treatment duration (95.46 days vs. 100.88 days, P = 0.698), time for CWC (68.06 days vs. 77.38 days, P = 0.431), and cost ($2756.78 vs. 2397.84 for breakeven rate, P = 0.640) with the exception of wound dressing costs ($329.19 vs. 146.47, P = 0.001). Healing rates may be affected with patient exclusions. Costs at physicians’ offices were not included. Incorporation of PT in wound care appeared to be cost effective. PT may thus be a good referral option for patients with wounds. However, the results should be interpreted cautiously and further studies are warranted. PMID:26656352

Chronic, non-healing wounds place a significant burden on patients and healthcare systems, resulting in impaired mobility, limb amputation, or even death. Chronic wounds result from a disruption in the highly orchestrated cascade of events involved in wound closure. Significant advances in our understanding of the pathophysiology of chronic wounds have resulted in the development of drugs designed to target different aspects of the impaired processes. However, the hostility of the wound environment rich in degradative enzymes and its elevated pH, combined with differences in the time scales of different physiological processes involved in tissue regeneration require the use of effective drug delivery systems. In this review, we will first discuss the pathophysiology of chronic wounds and then the materials used for engineering drug delivery systems. Different passive and active drug delivery systems used in wound care will be reviewed. In addition, the architecture of the delivery platform and its ability to modulate drug delivery are discussed. Emerging technologies and the opportunities for engineering more effective wound care devices are also highlighted. Copyright © 2018 Elsevier B.V. All rights reserved.

Development and validation of an online interactive, multimedia wound care algorithms program.

To provide education based on evidence-based and validated wound care algorithms we designed and implemented an interactive, Web-based learning program for teaching wound care. A mixed methods quantitative pilot study design with qualitative components was used to test and ascertain the ease of use, validity, and reliability of the online program. A convenience sample of 56 RN wound experts (formally educated, certified in wound care, or both) participated. The interactive, online program consists of a user introduction, interactive assessment of 15 acute and chronic wound photos, user feedback about the percentage correct, partially correct, or incorrect algorithm and dressing choices and a user survey. After giving consent, participants accessed the online program, provided answers to the demographic survey, and completed the assessment module and photographic test, along with a posttest survey. The construct validity of the online interactive program was strong. Eighty-five percent (85%) of algorithm and 87% of dressing choices were fully correct even though some programming design issues were identified. Online study results were consistently better than previously conducted comparable paper-pencil study results. Using a 5-point Likert-type scale, participants rated the program's value and ease of use as 3.88 (valuable to very valuable) and 3.97 (easy to very easy), respectively. Similarly the research process was described qualitatively as "enjoyable" and "exciting." This digital program was well received indicating its "perceived benefits" for nonexpert users, which may help reduce barriers to implementing safe, evidence-based care. Ongoing research using larger sample sizes may help refine the program or algorithms while identifying clinician educational needs. Initial design imperfections and programming problems identified also underscored the importance of testing all paper and Web-based programs designed to educate health care professionals or guide patient care.

Autologous cell-spray grafting of non-cultured epidermal cells is an innovative approach for the treatment of severe second-degree burns. After treatment, wounds are covered with dressings that are widely used in wound care management; however, little is known about the effects of wound dressings on individually isolated cells. The sprayed cells have to actively attach, spread, proliferate, and migrate in the wound for successful re-epithelialization, during the healing process. It is expected that exposure to wound dressing material might interfere with cell survival, attachment, and expansion. Two experiments were performed to determine whether some dressing materials have a negative impact during the early phases of wound healing. In one experiment, freshly isolated cells were seeded and cultured for one week in combination with eight different wound dressings used during burn care. Cells, which were seeded and cultured with samples of Adaptic(®), Xeroform(®), EZ Derm(®), and Mepilex(®) did not attach, nor did they survive during the first week. Mepitel(®), N-Terface(®), Polyskin(®), and Biobrane(®) dressing samples had no negative effect on cell attachment and cell growth when compared to the controls. In a second experiment, the same dressings were exposed to pre-cultured cells in order to exclude the effects of attachment and spreading. The results confirm the above findings. This study could be of interest for establishing skin cell grafting therapies in burn medicine and also for wound care in general. Copyright © 2015 Elsevier Ltd and ISBI. All rights reserved.

Wound healing research has progressed impressively over the past years. New insights into the pathogenesis of different chronic wounds and the study of novel treatment have made wound healing a model disorder and have revealed basic cellular and molecular mechanisms underlying chronic wounds. Although the observation is so obvious and simple, the interpretations by different observers can be quite variable. The interpretations of severity and change in severity by treatment may differ considerably between patient and practitioners. In this review we provide comprehensive view on different aspects of wound diagnostic, including clinical measurement, new biomarkers in wound pathology, proteases evaluation, and future noninvasive sensor-based devices. Wound caregivers are in the unique position of being able to observe the wound changes and describe these with knowledge and strict methodology, but also with the wide range of available wound diagnostic devices. The complexity of severity assessment in wound healing is reflected by the multiple clinical scores available. The best objective methods used to evaluate cutaneous tissue repair should have a high specificity and sensitivity and a low inter and intraobserver variation.

Wound Repair: Toward Understanding and Integration of Single-Cell and Multicellular Wound Responses

2016-01-01

The importance of wound healing to medicine and biology has long been evident, and consequently, wound healing has been the subject of intense investigation for many years. However, several relatively recent developments have added new impetus to wound repair research: the increasing application of model systems; the growing recognition that single cells have a robust, complex, and medically relevant wound healing response; and the emerging recognition that different modes of wound repair bear an uncanny resemblance to other basic biological processes such as morphogenesis and cytokinesis. In this review, each of these developments is described, and their significance for wound healing research is considered. In addition, overlapping mechanisms of single-cell and multicellular wound healing are highlighted, and it is argued that they are more similar than is often recognized. Based on this and other information, a simple model to explain the evolutionary relationships of cytokinesis, single-cell wound repair, multicellular wound repair, and developmental morphogenesis is proposed. Finally, a series of important, but as yet unanswered, questions is posed. PMID:21721944

Recent Advances and Critical Issues: Recent advances for each modality are provided as a basic synopsis of the technology followed by brief overviews of the most recent literature addressing its effectiveness for managing wound bioburden, and critical issues for each modality are provided as conclusions. Future Directions: This review highlights the need for further clinically relevant studies examining bacterial levels in addition to healing progression for each technology. PMID:25493207

Disrupting the biofilm matrix improves wound healing outcomes.

PubMed

Wolcott, R

2015-08-01

The most unyielding molecular component of biofilm communities is the matrix structure that it can create around the individual microbes that constitute the biofilm. The type of polymeric substances (polymeric sugars, bacterial proteins, bacterial DNA and even co-opted host substances) are dependent on the microbial species present within the biofilm. The extracellular polymeric substances that make up the matrix give the wound biofilm incredible colony defences against host immunity, host healing and wound care treatments. This polymeric slime layer, which is secreted by bacteria, encases the population of microbes, creating a physical barrier that limits the ingress of treatment agents to the bacteria. The aim of this study was to determine if degrading the wound biofilm matrix would improve wound healing outcomes and if so, if there was a synergy between treating agents that disrupted biofilm defenses with Next Science Wound Gel (wound gel) and cidal agents (topical antibiotics). A three-armed randomised controlled trial was designed to determine if standard of care (SOC) was superior to SOC plus wound gel (SOC + gel) and wound gel alone. The wound gel used in this study contains components that directly attack the biofilm extracellular polymeric substance. The gel was applied directly to the wound bed on a Monday-Wednesday-Friday interval, either alone or with SOC topical antibiotics. Using a surrogate endpoint of 50% reduction in wound volume, the results showed that SOC healed at 53%, wound gel healed at 80%, while SOC plus wound gel showed 93% of wounds being successfully treated. By directly targeting the wound biofilm matrix, wound healing outcomes are improved.

Workload and prevalence of open wounds in the community: French Vulnus initiative.

To calculate the prevalence of open cutaneous wounds presented on a routine working day in community settings in metropolitan France, and to estimate the workload associated with the care of these wounds by nurses, GPs and specialists (dermatologists, diabetologists and phlebologists). A transversal epidemiological survey was conducted on a randomly selected sample of the above practitioners between June and July 2008. The percentage of patients presenting on a routine working day with open a cutaneous lesion of any origin, location, size and duration was assessed. All local and systemic care performed on the patient during that day because of the wound was also recorded. In total, 475 GPs, 453 specialists and 238 nurses participated (n=1166) and saw a total of 29 663 patients, of whom 3037 presented with one or more cutaneous wound. The overall non-weighted prevalence of patients with a wound was 10.2% (95%CI: 9.9%;10.6%). This prevalence was similar for GPs (6.0%) and for specialists (6.9%), but was higher for nurses (22.0%). Forty-three per cent of all wounds had a duration of over 6 weeks. These chronic wounds were predominantly leg ulcers, diabetic foot ulcers or pressure ulcers, but also included wounds of all aetiologies. For 33% of all patients with wounds, the impact on their health status was serious to severe. The overwhelming majority of wounds (95%) required local care, including in 65% of cases cleansing and debridement. Despite its limitations, this initiative, the first of its type in France, strongly suggests that wound care constitutes an important part of routine care given by health professionals in the community, and for a substantial number of these patients, wounds represent a serious morbidity. The non-profit organisation 'Association Vivre avec une Plaie' financially supported this study. This association received unrestricted grants from the French Wound Healing Society (SFFPC) and a consortium of private companies (main sponsors: ConvaTec, Genevrier, Hartmann, KCI, Mölnycke, Smith & Nephew, Urgo; minor sponsors: Coloplast, Covidien, HNE) to fund the costs incurred by the methodological process and statistical analysis but had no input into the findings.

Objective Injuries, trauma and non-communicable diseases are responsible for a rising proportion of death and disability in low-income and middle-income countries. Delivering effective emergency and urgent healthcare for these and other conditions in resource-limited settings is challenging. In this study, we sought to examine and characterise emergency and urgent care capacity in a resource-limited setting. Methods We conducted an assessment within all 30 primary and secondary hospitals and within a stratified random sampling of 30 dispensaries and health centres in western Kenya. The key informants were the most senior facility healthcare provider and manager available. Emergency physician researchers utilised a semistructured assessment tool, and data were analysed using descriptive statistics and thematic coding. Results No lower level facilities and 30% of higher level facilities reported having a defined, organised approach to trauma. 43% of higher level facilities had access to an anaesthetist. The majority of lower level facilities had suture and wound care supplies and gloves but typically lacked other basic trauma supplies. For cardiac care, 50% of higher level facilities had morphine, but a minority had functioning ECG, sublingual nitroglycerine or a defibrillator. Only 20% of lower level facilities had glucometers, and only 33% of higher level facilities could care for diabetic emergencies. No facilities had sepsis clinical guidelines. Conclusions Large gaps in essential emergency care capabilities were identified at all facility levels in western Kenya.

New generation medical textiles are an important growing field with great expansion in wound management products. Virtually new products are coming but also well known materials with significantly improved properties using advanced technologies and new methods are in the centre of research which are highly technical, technological, functional, and effective oriented. The key qualities of fibres and dressings as wound care products include that they are bacteriostatic, anti-viral, fungistatic, non-toxic, high absorbent, non-allergic, breathable, haemostatic, biocompatible, and manipulatable to incorporate medications, also provide reasonable mechanical properties. Many advantages over traditional materials have products modified or blended with also based on alginate, chitin/chitosan, collagen, branan ferulate, carbon fibres. Textile structures used for modern wound dressings are of large variety: sliver, yarn, woven, non-woven, knitted, crochet, braided, embroidered, composite materials. Wound care also applies to materials like hydrogels, matrix (tissue engineering), films, hydrocolloids, foams. Specialized additives with special functions can be introduced in advanced wound dressings with the aim to absorb odours, provide strong antibacterial properties, smooth pain and relieve irritation. Because of unique properties as high surface area to volume ratio, film thinness, nano scale fibre diameter, porosity, light weight, nanofibres are used in wound care. The aim of this study is to outline and review the latest developments and advance in medical textiles and biopolymers for wound management providing the overview with generalized scope about novelties in products and properties.

Effects of a just-in-time educational intervention placed on wound dressing packages: a multicenter randomized controlled trial.

I compared the effects of a just-in-time educational intervention (educational materials for dressing application attached to the manufacturer's dressing package) to traditional wound care education on reported confidence and dressing application in a simulated model. Nurses from a variety of backgrounds were recruited for this study. The nurses possessed all levels of education ranging from licensed practical nurse to master of science in nursing. Both novice and seasoned nurses were included, with no stipulations regarding years of nursing experience. Exclusion criteria included nurses who spent less than 50% of their time in direct patient care and nurses with advanced wound care training and/or certification (CWOCN, CWON). Study settings included community-based acute care facilities, critical access hospitals, long-term care facilities, long-term acute care facilities, and home care agencies. No level 1 trauma centers were included in the study for geographical reasons. Participants were randomly allocated to control or intervention groups. Each participant completed the Kent Dressing Confidence Assessment tool. Subjects were then asked to apply the dressing to a wound model under the observation of either the principal investigator or a trained observer, who scored the accuracy of dressing application according to established criteria. None of the 139 nurses who received traditional dressing packaging were able to apply the dressing to a wound model correctly. In contrast, 88% of the nurses who received the package with the educational guide attached to it were able to apply the dressing to a wound model correctly (χ2 = 107.22, df = 1, P = .0001). Nurses who received the dressing package with the attached educational guide agreed that this feature gave them confidence to correctly apply the dressing (88%), while no nurse agreed that the traditional package gave him or her the confidence to apply the dressing correctly (χ2 = 147.47, df = 4, P < .0001). A just-in-time education intervention improved nurses' confidence when applying an unfamiliar dressing and accuracy of application when applying the dressing to a simulated model compared to traditional wound care education.

The study was conducted to determine the clinical and cost effectiveness of enhanced multi-disciplinary teams (EMDTs) vs. 'usual care' for the treatment of pressure ulcers in long term care (LTC) facilities in Ontario, Canada We conducted a multi-method study: a pragmatic cluster randomized stepped-wedge trial, ethnographic observation and in-depth interviews, and an economic evaluation. Long term care facilities (clusters) were randomly allocated to start dates of the intervention. An advance practice nurse (APN) with expertise in skin and wound care visited intervention facilities to educate staff on pressure ulcer prevention and treatment, supported by an off-site hospital based expert multi-disciplinary wound care team via email, telephone, or video link as needed. The primary outcome was rate of reduction in pressure ulcer surface area (cm2/day) measured on before and after standard photographs by an assessor blinded to facility allocation. Secondary outcomes were time to healing, probability of healing, pressure ulcer incidence, pressure ulcer prevalence, wound pain, hospitalization, emergency department visits, utility, and cost. 12 of 15 eligible LTC facilities were randomly selected to participate and randomized to start date of the intervention following the stepped wedge design. 137 residents with a total of 259 pressure ulcers (stage 2 or greater) were recruited over the 17 month study period. No statistically significant differences were found between control and intervention periods on any of the primary or secondary outcomes. The economic evaluation demonstrated a mean reduction in direct care costs of $650 per resident compared to 'usual care'. The qualitative study suggested that onsite support by APN wound specialists was welcomed, and is responsible for reduced costs through discontinuation of expensive non evidence based treatments. Insufficient allocation of nursing home staff time to wound care may explain the lack of impact on healing. Enhanced multi-disciplinary wound care teams were cost effective, with most benefit through cost reduction initiated by APNs, but did not improve the treatment of pressure ulcers in nursing homes. Policy makers should consider the potential yield of strengthening evidence based primary care within LTC facilities, through outreach by APNs. ClinicalTrials.gov identifier NCT01232764.

A Primer on the Acute Management of Intravenous Extravasation Injuries for the Plastic Surgeon

Intravenous therapy is a common practice among many specialties. Intravenous therapy extravasation is a potential complication to such therapy. Hospitals without a dedicated wound care team trained in these interventions will often default to plastic surgical consultation, making an understanding of available interventions essential to the initial evaluation and management of these injuries. The goal of this article was to provide plastic surgeons and health care providers with a general overview of the acute management of intravenous infiltration and extravasation injuries. Though the decision for surgical versus nonsurgical management is often a clear one for plastic surgeons, local interventions, and therapies are often indicated and under-utilized in the immediate postinfiltration period. Thorough knowledge of these interventions should be a basic requirement in the armamentarium of plastic surgery consultants. PMID:29876181

Treatment of the neonatal patient with clinically complex wounds creates a challenge due to the safety and efficacy issues associated with the use of many advanced wound care products. The purpose of this case series was to present outcomes of 3 neonates with wounds of differing etiologies managed by Active Leptospermum Honey (ALH). Clinical case series. Clinical experiences with 3 neonates, 1 male and 2 females, are described. These premature infants received care at Rush University Medical Center, Houston, Texas, or Driscoll Children's Hospital, Corpus Christi, Texas. Each neonate presented with dissimilar wounds and differing treatment goals. For a premature infant with left foot ischemia, ALH dressings allowed for removal of nonviable tissue and facilitated the granulation of the open wounds. This removal of nonviable tissue coupled with the facilitation of granulation tissue enabled the premature infant's toe tips to be salvaged without requiring aggressive surgical intervention. For the 2 preterm infants with extravasation of intravenous solutions, ALH dressings allowed healing and increased tissue granulation without any noted toxicity to the wound bed. Further, the method of action of ALH includes an osmotic pull effect that reduced periwound erythema and edema. Although the use of ALH has been well documented in adult care, these case studies demonstrate its potential use in different wound etiologies in 3 neonatal patients.

Modern collagen wound dressings: function and purpose.

PubMed

Fleck, Cynthia Ann; Simman, Richard

2010-09-01

Collagen, which is produced by fibroblasts, is the most abundant protein in the human body. A natural structural protein, collagen is involved in all 3 phases of the wound-healing cascade. It stimulates cellular migration and contributes to new tissue development. Because of their chemotactic properties on wound fibroblasts, collagen dressings encourage the deposition and organization of newly formed collagen, creating an environment that fosters healing. Collagen-based biomaterials stimulate and recruit specific cells, such as macrophages and fibroblasts, along the healing cascade to enhance and influence wound healing. These biomaterials can provide moisture or absorption, depending on the delivery system. Collagen dressings are easy to apply and remove and are conformable. Collagen dressings are usually formulated with bovine, avian, or porcine collagen. Oxidized regenerated cellulose, a plant-based material, has been combined with collagen to produce a dressing capable of binding to and protecting growth factors by binding and inactivating matrix metalloproteinases in the wound environment. The increased understanding of the biochemical processes involved in chronic wound healing allows the design of wound care products aimed at correcting imbalances in the wound microenvironment. Traditional advanced wound care products tend to address the wound's macroenvironment, including moist wound environment control, fluid management, and controlled transpiration of wound fluids. The newer class of biomaterials and wound-healing agents, such as collagen and growth factors, targets specific defects in the chronic wound environment. In vitro laboratory data point to the possibility that these agents benefit the wound healing process at a biochemical level. Considerable evidence has indicated that collagen-based dressings may be capable of stimulating healing by manipulating wound biochemistry.

Clinical and economic benefit of enzymatic debridement of pressure ulcers compared to autolytic debridement with a hydrogel dressing.

Waycaster, Curtis; Milne, Catherine T

2013-07-01

The purpose of this study was to determine the cost-effectiveness of enzymatic debridement using collagenase relative to autolytic debridement with a hydrogel dressing for the treatment of pressure ulcers. A 3-stage Markov model was used to determine the expected costs and outcomes of wound care for collagenase and hydrogel dressings. Outcome data used in the analysis were taken from a randomized clinical trial that directly compared collagenase and hydrogel dressings. The primary outcome in the clinical trial was the proportion of patients achieving a closed epithelialized wound. Transition probabilities for the Markov states were estimated from the clinical trial. A 1-year time horizon was used to determine the expected number of closed wound days and the expected costs for the two alternative debridement therapies. Resource utilization was based on the wound care treatment regimen used in the clinical trial. Resource costs were derived from standard cost references and medical supply wholesalers. The economic perspective taken was that of the long-term care facility. No cost discounting was performed due to the short time horizon of the analysis. A deterministic sensitivity analysis was conducted to analyze economic uncertainty. The number of expected wound days for the collagenase and hydrogel cohorts are estimated at 48 and 147, respectively. The expected direct cost per patient for pressure ulcer care was $2003 for collagenase and $5480 for hydrogel debridement. The number of closed wound days was 1.5-times higher for collagenase (317 vs 218 days) than with the hydrogel. The estimated cost/closed wound day was 4-times higher for the hydrogel ($25) vs collagenase ($6). In this Markov model based on a randomized trial of pressure ulcer care in a long-term care setting collagenase debridement was economically dominant over autolytic debridement, yielding better outcomes at a lower total cost. Since it was a single institution study with a small sample size, the results should be interpreted with caution. Specifically, the findings may not necessarily be generalized to other hydrogel dressings, healthcare settings, age groups, or to wounds of other etiologies.

[Continuous medical education of general practitioners/family doctors in chronic wound care].

A number of healthcare professionals, specialists in different fields and with different levels of education, as well as non-healthcare professionals, are involved in the care of chronic wound patients, thus forming a multidisciplinary team that is not only responsible for the course and outcome of treatment, but also for the patient quality of life. Family doctor is also member of the team the task of which is to prevent, diagnose, monitor and anticipate complications and relapses, as well as complete recovery of chronic wound patients, with the overall care continuing even after the wound has healed, or is involved in palliative care. A family medicine practitioner with specialized education and their team of associates in the primary health care, along with material conditions and equipment improvement, can provide quality care for patients with peripheral cardiovascular diseases and chronic wounds, organized according to the holistic approach. It is essential that all professional associations of family medicine as well as professional associations of other specialties - fields that are involved in wound prevention and treatment - be included in developing the continuous medical education program. The benefits of modern information technology should be used to good advantage. The education should be adapted to the needs of family practitioners in terms of the form, place, time, volume, financial affordability and choice of topic. The interest shown in team education should be transformed into specialized programs in the creation of which it is essential to include both physicians and nurses and their respective professional associations. Special attention should be paid to education and training of young doctors/nurses, those with less work experience, those that have not yet been part of such education, those that lack experience in working with wound patients, those whose teams deal mostly with elderly patients, and also residents in family medicine and Nursing College students.

Complex wounds such as leg and foot ulcers are common, resource intensive and have negative impacts on patients' wellbeing. Evidence-based decision-making, substantiated by high quality evidence such as from systematic reviews, is widely advocated for improving patient care and healthcare efficiency. Consequently, we set out to classify and map the extent to which up-to-date systematic reviews containing robust evidence exist for wound care uncertainties prioritised by community-based healthcare professionals. We asked healthcare professionals to prioritise uncertainties based on complex wound care decisions, and then classified 28 uncertainties according to the type and level of decision. For each uncertainty, we searched for relevant systematic reviews. Two independent reviewers screened abstracts and full texts of reviews against the following criteria: meeting an a priori definition of a systematic review, sufficiently addressing the uncertainty, published during or after 2012, and identifying high quality research evidence. The most common uncertainty type was 'interventions' 24/28 (85%); the majority concerned wound level decisions 15/28 (53%) however, service delivery level decisions (10/28) were given highest priority. Overall, we found 162 potentially relevant reviews of which 57 (35%) were not systematic reviews. Of 106 systematic reviews, only 28 were relevant to an uncertainty and 18 of these were published within the preceding five years; none identified high quality research evidence. Despite the growing volume of published primary research, healthcare professionals delivering wound care have important clinical uncertainties which are not addressed by up-to-date systematic reviews containing high certainty evidence. These are high priority topics requiring new research and systematic reviews which are regularly updated. To reduce clinical and research waste, we recommend systematic reviewers and researchers make greater efforts to ensure that research addresses important clinical uncertainties and is of sufficient rigour to inform practice.

Cutaneous delayed wounds are a challenging clinical problem, and vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) exhibit key roles in wound healing. Moist exposed burn ointment (MEBO), a Chinese burn ointment with a USA patented formulation, has been reported to promote chronic ischemic and neurogenic ulcer healing in patients; however, the underlying mechanisms remain unclear. In the present study, MEBO significantly promoted the formation of granulation tissue in cutaneous excisional wounds, shortened the time of wound healing, and increased neovascularization and the number of fibroblasts. Furthermore, as well as enhancing the protein expression, MEBO application also increased the gene expression of VEGF and bFGF. The results indicate that MEBO promotes cutaneous excisional wound healing by at least partially enhancing VEGF and bFGF production, implicating the potential uses of MEBO for delayed cutaneous wound healing.

Conservative sharp wound debridement: an overview of Canadian education, practice, risk, and policy.

The purpose of this study was to describe the education, policy, practice, and risk management strategies of nurses performing conservative sharp wound debridement (CSWD) in Canada, prior to the release of the Canadian Association for Enterostomal Therapy Evidence-Based Recommendations for Conservative Sharp Wound Debridement. Data collection was based on a nonrandomized, nonexperimental study design and reported using descriptive statistics. Invitations for health care professionals to participate in a CSWD scan were sent to 4315 people via e-mail through the membership lists of 2 Canadian voluntary professional wound care associations. Skip logic screened out respondents who had no experience in CSWD (n = 57). The total number of professionals who participated was 487. A 26-question electronic scan addressed demographics, education, policy, practice, and risk/quality issues related to CSWD. A comment section was included for some questions. A selected subsample of 397 nurses was chosen from the original total of 487 respondents. Nonnurse respondents were excluded due to the low total number of participants in each of these other professional categories. Nurses perform CSWD in all types of care settings in Canada from outpost nursing stations to hospital wards, homes, and long-term care facilities. The wound education preparation reported varied. The most frequently reported formal wound care education was a 2-day course (59%; n = 220), followed by an enterostomal therapy course (42%; n = 155) and the International Interdisciplinary Wound Care Course (26%; n = 98), with overlapping preparation evident. Eleven percent of respondents (n = 47) reported having taken no formal wound course, and 7% (n = 27) taught themselves to perform CSWD. Twenty-eight percent of nurses (n = 112) were unclear about whether CSWD was within their scope of practice or replied that it was not, and 69% (n = 273) did not know if there was provincial legislation that restricted their practice of CSWD. Forty-eight percent of nurses (n = 181) reported that their institutions do not have policies on CSWD, and 9% (n = 35) did not know. Adverse events associated with CSWD were reported by 196 respondents, with minor bleeding reported most frequently (98% n = 192) by those who answered the question. The education, policy, practice, and risk management of nurses practicing CSWD could benefit from development and dissemination of a set of National Standards and Competencies for this high-risk wound intervention.

Novel approaches including nonpharmacological methodologies for prevention and control of microbial pathogens and emerging antibiotic resistance are urgently needed. Procellera is a wound care device consisting of a matrix of alternating silver (Ag) and zinc (Zn) dots held in position on a polyester substrate with a biocompatible binder. This electroceutical medical device is capable of generating a direct current voltage (0.5-0.9 Volts). Wound dressings containing metals such as Ag and/or Zn as active ingredients are being used for control of colonized and infected wounds. Reports on the presence of electric potential field across epithelium and wound current on wounding have shown that wound healing is enhanced in the presence of an external electrical field. However, majority of the electrical devices require an external power source for delivering pulsed or continuous electric power at the wound site. A microelectric potential-generating system without an external power source is an ideal treatment modality for application in both clinical and field settings. The research presented herein describes efficacy evaluation of a wireless bioelectric dressing against both planktonic and biofilm forms of wound pathogens including multidrug resistant organisms.

To clarify the histopathology of acute osteomyelitis, chronic osteomyelitis, primary vasculitis, and secondary-type vasculitis. This continuing education activity is intended for physicians and nurses with an interest in skin and wound care. After participating in this educational activity, the participant should be better able to:1. Describe the parameters and significance of this study.2. Identify chronic wound diagnosis and treatment.3. Differentiate the histopathology of osteomyelitis and vasculitis. The presence of a chronic wound can result in significant morbidity/mortality. Understanding the pathological alterations of wound tissue that are refractory to standard wound therapy is essential for effective wound management and healing. The authors describe 4 wound etiologies, specifically, acute osteomyelitis, chronic osteomyelitis, primary vasculitis, and secondary-type vasculitis. A tertiary care hospital. A retrospective review of 1392 wound operations performed during a 24-month period at a tertiary care hospital was conducted. Tissue specimens reviewed included soft tissue infections of the lower extremity, sacrum, hip/pelvis, trunk, perineum, and buttocks. Acute osteomyelitis is defined as bone tissue with a predominance of polymorphonuclear leukocytes, evidence of osteoclast bone resorption with scalloping of the cortical bone edges, and bone detritus. Chronic osteomyelitis is defined as bone tissue with a significant amount of fibrosis surrounding devitalized tissue and heavy infiltration of lymphocytes and plasma cells. Primary-type vasculitis is defined primarily as inflammation and necrosis of blood vessel walls. In cutaneous lesions of granulomatosis with polyangiitis, ulceration with numerous inflammatory granulomas is seen in the papillary dermis. Secondary vasculitis is defined by vessel wall infiltration by inflammatory cells and fibrinoid necrosis of the small vessel wall. Pathologies of these 4 types of wounds can complicate standard algorithms designed for diagnosis and treatment, and accurate diagnosis through histopathologic analysis can help tailor targeted treatment.

PDGF-BB Does Not Accelerate Healing in Diabetic Mice with Splinted Skin Wounds

Topical application of platelet-derived growth factor-BB (PDGF-BB) is considered to accelerate tissue repair of impaired chronic wounds. However, the vast literature is plagued with conflicting reports of its efficacy in animal models and this is often influenced by a wide array of experimental variables making it difficult to compare the results across the studies. To mitigate the confounding variables that influence the efficacy of topically applied PDGF-BB, we used a controlled full thickness splinted excisional wound model in db/db mice (type 2 diabetic mouse model) for our investigations. A carefully-defined silicone-splinted wound model, with reduced wound contraction, controlled splint and bandage maintenance, allowing for healing primarily by reepithelialization was employed. Two splinted 8 mm dorsal full thickness wounds were made in db/db mice. Wounds were topically treated once daily with either 3 µg PDGF-BB in 30 µl of 5% PEG-PBS vehicle or an equal volume of vehicle for 10 days. Body weights, wound contraction, wound closure, reepithelialization, collagen content, and wound bed inflammation were evaluated clinically and histopathologically. The bioactivity of PDGF-BB was confirmed by in vitro proliferation assay. PDGF-BB, although bioactive in vitro, failed to accelerate wound healing in vivo in the db/db mice using the splinted wound model. Considering that the predominant mechanism of wound healing in humans is by re-epeithelialization, the most appropriate model for evaluating therapeutics is one that uses splints to prevent excessive wound contraction. Here, we report that PDGF-BB does not promote wound closure by re-epithelialization in a murine splinted wound model. Our results highlight that the effects of cytoactive factors reported in vivo ought to be carefully interpreted with critical consideration of the wound model used. PMID:25121729

Burn wound care procedures are very painful and lead to distress. Live music therapy has shown beneficial effects on distress and pain in specific pediatric patient populations. In this study we measured whether live music therapy has beneficial effects in terms of less distress and pain in children with burns after wound care procedures. This randomized assessor-blinded controlled trial (RCT) took place at the burns unit of the Red Cross War Memorial Children's Hospital, Cape Town, South Africa. It included newly admitted inpatients between the ages of 0 and 13 years undergoing their first or second wound care procedures. Excluded were children with a hearing impairment or low level of consciousness. The intervention group received one live music therapy session directly after wound care in addition to standard care. The control group received standard care only. The primary outcome was distress measured with the Observational Scale of Behavioral Distress-revised (OSBD-r). The secondary outcome was pain measured with the COMFORT-behavioral scale (COMFORT-B). In addition, in children older than 5 years self-reported distress with the validated Wong-Baker scale (FACES) and pain with the Faces Pain Scale-Revised (FPS-R) were measured. Patients in both groups were videotaped for three minutes before wound care; during the music therapy or the control condition; and for two minutes thereafter. Two researchers, blinded to the study condition, independently scored the OSBD-r and the COMFORT-B from the video footage before and after music therapy. We included 135 patients, median age 22.6 months (IQR 15.4-40.7 months). Change scores did not significantly differ between the intervention and the control groups for either distress (p=0.53; d=0.11; 95% CI -0.23 to 0.45) or pain (p=0.99; d=0.04; 95% CI -0.30 to 0.38). Self-reported distress in a small group of children (n=18) older than 5 years indicated a significant reduction in distress after live music therapy (p=0.05). Live music therapy was not found effective in reducing distress and pain in young children after burn wound care. Older children might be more responsive to this intervention.

Treating a pressure ulcer with bio-electric stimulation therapy.

PubMed

Hampton, Sylvie; Collins, Fiona

Mr Jones lived independently until he developed necrotic pressure ulcers over his heels and could no longer mobilize to care for himself. He was transferred to a nursing home where he lived for 18 months and where the nurses could care for his wounds. The wound had been on his right heel without changing over the 18 months and, although attempts to hydrate the eschar had been somewhat successful, the necrotic tissue proved stubborn creating large quantity of fibrous slough. Mr Jones was initially assessed by the tissue viability consultant on 14 March 2005 and agreed to the application of bio-electric stimulation therapy (POSiFEC). The wound change was immediate and was fully healed by 16 June 2005, 12 weeks after his initial assessment. This article outlines his care and the background to bio-electrical stimulation in wounds.

Complex wounds present a substantial economic burden on healthcare systems, costing billions of dollars annually in North America alone. The prevalence of complex wounds is a significant patient and societal healthcare concern and cost-effective wound care management remains unclear. This article summarizes the cost-effectiveness of interventions for complex wound care through a systematic review of the evidence base. We searched multiple databases (MEDLINE, EMBASE, Cochrane Library) for cost-effectiveness studies that examined adults treated for complex wounds. Two reviewers independently screened the literature, abstracted data from full-text articles, and assessed methodological quality using the Drummond 10-item methodological quality tool. Incremental cost-effectiveness ratios were reported, or, if not reported, calculated and converted to United States Dollars for the year 2013. Overall, 59 cost-effectiveness analyses were included; 71% (42 out of 59) of the included studies scored 8 or more points on the Drummond 10-item checklist tool. Based on these, 22 interventions were found to be more effective and less costly (i.e., dominant) compared to the study comparators: 9 for diabetic ulcers, 8 for venous ulcers, 3 for pressure ulcers, 1 for mixed venous and venous/arterial ulcers, and 1 for mixed complex wound types. Our results can be used by decision-makers in maximizing the deployment of clinically effective and resource efficient wound care interventions. Our analysis also highlights specific treatments that are not cost-effective, thereby indicating areas of resource savings. Please see related article: http://dx.doi.org/10.1186/s12916-015-0288-5.

Wound Healing Essentials: Let There Be Oxygen

Sen, Chandan K.

2009-01-01

The state of wound oxygenation is a key determinant of healing outcomes. From a diagnostic standpoint, measurements of wound oxygenation are commonly used to guide treatment planning such as amputation decision. In preventive applications, optimizing wound perfusion and providing supplemental O2 in the peri-operative period reduces the incidence of post-operative infections. Correction of wound pO2 may, by itself, trigger some healing responses. Importantly, approaches to correct wound pO2 favorably influence outcomes of other therapies such as responsiveness to growth factors and acceptance of grafts. Chronic ischemic wounds are essentially hypoxic. Primarily based on the tumor literature, hypoxia is generally viewed as being angiogenic. This is true with the condition that hypoxia be acute and mild to modest in magnitude. Extreme near-anoxic hypoxia, as commonly noted in problem wounds, is not compatible with tissue repair. Adequate wound tissue oxygenation is required but may not be sufficient to favorably influence healing outcomes. Success in wound care may be improved by a personalized health care approach. The key lies in our ability to specifically identify the key limitations of a given wound and in developing a multifaceted strategy to specifically address those limitations. In considering approaches to oxygenate the wound tissue it is important to recognize that both too little as well as too much may impede the healing process. Oxygen dosing based on the specific need of a wound therefore seems prudent. Therapeutic approaches targeting the oxygen sensing and redox signaling pathways are promising. PMID:19152646

A chronic wound fails to complete an orderly and timely reparative process and places patients at increased risk for wound complications that negatively impact quality of life and require greater health care expenditure. The role of extracellular matrix (ECM) is critical in normal and chronic wound repair. Not only is ECM the largest component of the dermal skin layer, but also ECM proteins provide structure and cell signalling that are necessary for successful tissue repair. Chronic wounds are characterised by their inflammatory and proteolytic environment, which degrades the ECM. Human acellular dermal matrices, which provide an ECM scaffold, therefore, are being used to treat chronic wounds. The ideal human acellular dermal wound matrix (HADWM) would support regenerative healing, providing a structure that could be repopulated by the body's cells. Experienced wound care investigators and clinicians discussed the function of ECM, the evidence related to a specific HADWM (Graftjacket(®) regenerative tissue matrix, Wright Medical Technology, Inc., licensed by KCI USA, Inc., San Antonio, TX), and their clinical experience with this scaffold. This article distills these discussions into an evidence-based and practical overview for treating chronic lower extremity wounds with this HADWM. © 2013 The Authors.

Cutaneous wound healing: Current concepts and advances in wound care

PubMed Central

Klein, Kenneth C; Guha, Somes Chandra

2014-01-01

A non-healing wound is defined as showing no measurable signs of healing for at least 30 consecutive treatments with standard wound care.[1] It is a snapshot of a patient's total health as well as the ongoing battle between noxious factors and the restoration of optimal macro and micro circulation, oxygenation and nutrition. In practice, standard therapies for non-healing cutaneous wounds include application of appropriate dressings, periodic debridement and eliminating causative factors.[2] The vast majority of wounds would heal by such approach with variable degrees of residual morbidity, disability and even mortality. Globally, beyond the above therapies, newer tools of healing are selectively accessible to caregivers, for various logistical or financial reasons. Our review will focus on the use of hyperbaric oxygen therapy (HBOT), as used at our institution (CAMC), and some other modalities that are relatively accessible to patients. HBOT is a relatively safe and technologically simpler way to deliver care worldwide. However, the expense for including HBOT as standard of care for recognized indications per UHMS(Undersea and Hyperbaric Medical Society) may vary widely from country to country and payment system.[3] In the USA, CMS (Centers for Medicare and Medicaid Services) approved indications for HBOT vary from that of the UHMS for logistical reasons.[1] We shall also briefly look into other newer therapies per current clinical usage and general acceptance by the medical community. Admittedly, there would be other novel tools with variable success in wound healing worldwide, but it would be difficult to include all in this treatise. PMID:25593414

Fundamentals of pain management in wound care.

PubMed

Coulling, Sarah

Under-treated pain can result in a number of potentially serious sequelae (Australian and New Zealand College of Anaesthetists, 2006), including delayed mobilization and recovery, cardiac complications, thromboses, pulmonary complications, delayed healing, psychosocial problems and chronic pain syndromes. This article considers pain management in the context of painful wounds. An international comparative survey on wound pain (European Wound Management Association, 2002) found that practitioners in the wound care community tend to focus on healing processes rather than the patient's total pain experience involving an accurate pain assessment and selection of an appropriate pain management strategy. Procedural pain with dressing removal and cleansing caused the greatest concerns. An overview of simple, evidence-based drug and non-drug techniques is offered as potential strategies to help minimize the experience of pain.

Chronic wounds are a major health burden and have a severe impact on well-being. This synthesis of qualitative studies was undertaken to inform a health technology assessment of antimicrobial wound dressings. It aimed to explore patients' experiences of chronic wounds and determine improvements for clinical practice. Inclusion criteria included use of qualitative methods, and English language publication. Databases searched included MEDLINE (Ovid), MEDLINE in Process (Ovid), EMBASE (Ovid), CINAHL (EBSCOHost), and PsychInfo (EBSCOHost). Searches were limited to 1990-2014. The method of analysis was Framework synthesis. A total of 20 studies were included. The synthesis confirmed the severe physical, social and psychological impact of the chronic wound. Inadequately controlled pain and sleeplessness, restrictions to lifestyle, and the loss of previous life roles can lead to feelings of hopelessness and helplessness and therefore depression and anxiety. Dressings and dressing changes are a key aspect of treatment and provide opportunities for positive interaction and person centred-care. People with chronic wounds can be supported to live well within the severe physical, psychological and social restrictions of a chronic wound. Effective clinical pain management and the recognition of the experience of acute and chronic pain are of the utmost importance to people with a chronic wound. Treatment should not be purely focused on healing but incorporate symptom management, coping and wellbeing via person-centred and holistic care. Copyright © 2017 Tissue Viability Society.

Post-surgical wound management of pilonidal cysts with a haemoglobin spray: a case series.

PubMed

Mustafi, N; Engels, P

2016-04-01

Painful acute cysts in the natal cleft or lower back, known as pilonidal sinus disease, are a severe burden to many younger patients. Although surgical intervention is the preferred first line treatment, postsurgical wound healing disturbances are frequently reported due to infection or other complications. Different treatment options of pilonidal cysts have been discussed in the literature, however, no standardised guideline for the postsurgical wound treatment is available. After surgery, a common recommended treatment to patients is rinsing the wound with clean water and dressing with a sterile compress. We present a case series of seven patients with wounds healing by secondary intention after surgical intervention of a pilonidal cyst. The average age of the patients was 40 years old. Of the seven patients, three had developed a wound healing disturbance, one wound had started to develop a fibrin coating and three were in a good condition. The applied wound care regimens comprised appropriate mechanical or autolytic debridement, rinsing with an antimicrobial solution, haemoglobin application, and primary and secondary dressings. In all seven cases a complete wound closure was achieved within an average of 76 days with six out of seven wounds achieving wound closure within 23-98 days. Aesthetic appearance was deemed excellent in five out of seven cases excellent and acceptable in one. Treatment of one case with a sustained healing disturbance did result in wound closure but with a poor aesthetic outcome and an extensive cicatrisation of the new tissue. Based on these results we recommend that to avoid healing disturbances of wounds healing by secondary intention after surgical pilonidal cyst intervention, an adequate wound care regime comprising appropriate wound debridement, rinsing, topically applied haemoglobin and adequate wound dressing is recommendable as early as possible after surgery.

Collagen-based dressings are of great interest in wound care. However, evidence supporting their mechanism of action in a wound setting in vivo is scanty. This work providesfirst results from a pre-clinical swine model of excisional wounds elucidating the mechanism of action of a modified collagen gel (MCG) dressing. Following wounding, wound-edge tissue was collected at specific time intervals (3, 7, 14, and 21 days post-wounding). On day 7, histological analysis showed significant increase in the length of rete ridges suggesting improved biomechanical properties of the healing wound tissue. Rapid and transient mounting of inflammation is necessary for efficient healing. MCG significantly accelerated neutrophil and macrophages recruitment to the wound site on day 3 and day 7 with successful resolution of inflammation on day 21. MCG induced MCP-1 expression in neutrophil-like HL-60 cells in vitro. In vivo, MCG treated wound tissue displayed elevated VEGF expression. Consistently, MCG-treated wounds displayed significantly higher abundance of endothelial cells with increased blood flow to the wound area indicating improved vascularization. This observation was explained by the finding that MCG enhanced proliferation of wound-site endothelial cells. In MCG-treated wound tissue, Masson’s Trichrome and Picrosirius red staining showed higher abundance of collagen and increased collagen type I:III ratio. This work presents first evidence from a pre-clinical experimental setting explaining how a collagen-based dressing may improve wound closure by targeting multiple key mechanisms as compared to standard of care i.e., Tegadem treated wounds. The current findings warrant additional studies to determine whether the responses to the MCG are different from other modified or unmodified collagen based products used in clinical setting.

Wound healing problems and chronic wounds can be a therapeutic challenge are a frequent problem after radiotherapy. They can appear spontaneously or after further surgery. The permanently altered tissue is associated with recurrent bacterial infections with weeping wounds, which cannot be treated sufficiently by conventional conservative wound care. The topical application of medical honey seems to have a positive effect in such cases. The aim of this prospectively study is to check this effectiveness in the treatment of wound healing problems and chronic wounds in the head and neck area of irradiated patients. In the period of July 2012 until August 2013 nine patients were treated with medical honey. All pa-tients had previously radiotherapy in the head and neck area. 5 patients had protracted wound healing problems after salvage surgery. The remaining 4 cases had spontaneously dehiscenced wounds at the beginning of the study. The wound healing was confirmed by measurement of the wound edges and depth and by adequate photo documentation. In all cases, the conventional wound care was unsuccessfully. In 8 of 9 cases, the wounds could be brought to cure by the application of medical honey over 3-8 weeks. Side effects or allergic reactions to the medical honey were not seen in any -cases. Based on our clinical experience we believe that the topical application of medical honey in non-healing or recurrent wounds in the head and neck area after radiotherapy is a reason-able and successful alternative therapy. © Georg Thieme Verlag KG Stuttgart · New York.

Expeditionary maneuver warfare and the asymmetric battlefield have forced changes in the traditional methods with which we deliver anesthesia and surgery to the wounded. Although in many ways similar to how we have operated on the wounded for the past half century, new advances in diagnostic and therapeutic modalities and doctrinal shifts have changed the face of the battlefield hospital. In this article, the authors discuss these changes in regard to anesthetic care for surgical and pain management for wounded airmen, sailors, soldiers, and marines.

Hepatitis C Virus: Patients' Risk Factors and Knowledge in an Urban Clinic Providing Wound Care.

Affecting about 3.2 million people in the United States, hepatitis C virus (HCV) is the primary cause of chronic liver disease and a global health challenge. Hepatitis C virus can affect the functioning of the liver, the health of the person, and thus wound healing. This quality project explores risk factors of HCV; self-reported screening, occurrence, and treatment; and knowledge of HCV in patients seeking wound care in an urban clinic. Demographic risk factors, HCV history, and responses to a 22-item true-false-don't know HCV Knowledge Test were obtained from 58 patients. Risk factors included age (mean, 61.07 years), male sex (n = 41), non-Hispanic black race/ethnicity (n = 51), and history of injection drugs (n = 38). Thirty-nine (67.2%) stated they had been screened for HCV; 31 were told they were infected. Only 14 went to a clinic for HCV care and 11 reported they were treated. The mean number of correct answers on the HCV Knowledge Test was 14.4 (standard deviation, 5.7). This urban clinic had patients with multiple HCV risk factors; they often lacked HCV screening and/or referral for treatment. Their HCV knowledge was generally low. As a major public health problem that could impact wound healing, wound care practitioners should ask patients about their HCV status, encourage HCV screening and care, and provide HCV information.

Effectiveness of a monofilament wound debridement pad at removing biofilm and slough: ex vivo and clinical performance.

PubMed

Schultz, Gregory S; Woo, Kevin; Weir, Dot; Yang, Qingping

Removal of slough and other devitalised tissue is an important step in biofilm-based wound care (BBWC) and wound bed preparation. Debridement is key to management of both slough and biofilm, and a number of methods are available to achieve this, including surgical/sharp and mechanical debridement. Developments have led to products indicated for debridement of wounds, including a sterile pad consisting of monofilament fibres. Our aim is to examine the effectiveness of a monofilament wound debridement pad (WDP), Debrisoft. We assessed the WDP, in laboratory tests, for the removal of mature biofilm from porcine dermal tissue in an ex vivo model, and the clinical management of sloughy wounds that would benefit from debridement. We used the UPPER score to determine the superficial infection status. The WDP was effective in removing biofilm from porcine dermal tissue. A case series of 10 patients with chronic wounds suggested that the WDP was beneficial in the removal of slough. All chronic wounds had slough and were cleaned weekly, for four weeks, using the MDP to achieve improved healing and a clean wound bed. The average wound size decreased from 8.09cm 2 at baseline to 2.3cm 2 at week four, with three wounds healed completely. Exudate was reduced, and the UPPER score improved in every patient. These results indicate that the WDP effectively debrides biofilm and slough, and contributes to care that follows the principles of wound bed preparation and BBWC.

We have previously demonstrated that the Society for Vascular Surgery Wound, Ischemia, and foot Infection (WIfI) classification correlates with wound healing time in patients with diabetic foot ulcers (DFUs) treated in a multidisciplinary setting. Our aim was to assess whether the charges and costs associated with DFU care increase with higher WIfI stages. All patients presenting to our multidisciplinary diabetic limb preservation service from June 2012 to June 2016 were enrolled in a prospective database. Inpatient and outpatient charges, costs, and total revenue from initial visit until complete wound healing were compared for wounds stratified by WIfI classification. A total of 319 wound episodes in 248 patients were captured, including 31% WIfI stage 1, 16% stage 2, 30% stage 3, and 24% stage 4 wounds. Limb salvage at 1 year was 95% ± 2%, and wound healing was achieved in 85% ± 2%. The mean number of overall inpatient admissions (stage 1, 2.07 ± 0.48 vs stage 4, 3.40 ± 0.27; P < .001), procedure-related admissions (stage 1, 1.86 ± 0.45 vs stage 4, 2.28 ± 0.24; P < .001), and inpatient vascular interventions (stage 1, 0.14 ± 0.10 vs stage 4, 0.80 ± 0.12; P < .001) increased significantly with increasing WIfI stage. There were no significant differences in mean number of inpatient podiatric interventions or outpatient procedures between groups (P ≥ .10). The total cost of care per wound episode increased progressively from stage 1 ($3995 ± $1047) to stage 4 ($50,546 ± $4887) wounds (P < .001). Inpatient costs were significantly higher for advanced stage wounds (stage 1, $21,296 ± $4445 vs stage 4, $54,513 ± $5001; P < .001), whereas outpatient procedure costs were not significantly different between groups (P = .72). Overall, hospital total revenue increased with increasing WIfI stage (stage 1, $4182 ± $1185 vs stage 4, $55,790 ± $5540; P < .002). Increasing WIfI stage is associated with a prolonged wound healing time, a higher number of surgical procedures, and an increased cost of care. While limb salvage outcomes are excellent, the overall cost of DFU care from presentation to healing is substantial, especially for patients with advanced (WIfI stage 3/4) disease treated in a multidisciplinary setting.

2008-11-01

This retrospective observational study was designed to review the use of a silver-coated polymeric substrate on various types of chronic wounds at the Mayo Clinic in Rochester, Minnesota. The study was set in a community and referral multidisciplinary vascular wound clinic. The authors identified the first 112 patients treated with a silver dressing in the center. Of these, 15 were lost to follow-up or had incomplete data. Ninety-seven patients were included in the study. Thirty-seven of these 97 patients had multiple wounds; however, 1 wound per person was randomly chosen for analysis. The median age of these patients was 69 years. A wound was considered healed when the wound was completely epithelialized. Of the 97 wounds evaluated, the primary etiologies were as follows: 20 (20.6%) were neurotrophic, 24 (24.7%) were ischemic (arterial, arteriolar, or vasculitic), 20 (20.6%) were venous, 7 (7.2%) were traumatic, and 16 (16.5%) were multifactorial. The silver dressing was the primary wound care product on all wounds. Silverlon (Argentum LLC, Chicago, Illinois) was the silver dressing used for this study. The frequency of dressing changes and use of secondary dressings, to keep the wound moist, were based on the amount of drainage, debris, and slough on the wound. Data pertaining to patient demographics, risk factors, wound etiology, noninvasive arterial vascular studies, frequency of dressing changes, wound discomfort, wound size, and wound duration were collected by retrospective chart review. Thirty-five of the 97 wounds (36.1%) healed. The 62 nonhealed wounds (63.9%) decreased in size by a median of 55.2%. Among the 68 patients who had reported discomfort before the study, 77.9% reported no change in discomfort, 17.7% reported increased pain, and 4.4% reported decreased pain. A silver-coated polymeric substrate (Silverlon) can be used as an effective primary wound care dressing in patients with active wounds.

This study investigated clinical outcomes in chronic nonhealing wounds following the short-term use of an enhanced, near-physiological concentration of platelet-rich plasma (PRP) gel (AutoloGel System, Cytomedix, Inc, Gaithersburg, Maryland). Study design was a large, observational case series using a multicenter registry database (all wounds included), which compared different populations within the database. Thirty-nine centers contributed to the registry, including long-term acute-care centers, outpatient clinics, a durable medical equipment company, a home health agency, and a long-term-care center. The target population included 285 chronic wounds (patient n = 200). Wound etiologies included diabetic, pressure, or venous ulcer; dehisced, surgical, or traumatic wound; and wounds of other etiologies. Therapeutic, PRP gel is produced from patient blood utilizing autologous platelets and plasma that contribute growth factors, cytokines, and chemokines, in a fibrin matrix. Area and volume of the wound and the linear total of undermining and sinus tracts/tunneling were calculated. Clinical relevance was determined by analyzing outcomes in wounds that responded to treatment. A positive response occurred in 96.5% of wounds within 2.2 weeks with 2.8 treatments. In 86.3% of wounds, 47.5% area reduction occurred, and 90.5% of wounds had a 63.6% volume reduction. In 89.4% undermined and 85.7% of sinus tracts/tunneling wounds, 71.9% and 49.3% reductions in linear total were observed, respectively. In chronic wounds recalcitrant to other treatments, utilization of PRP gel can restart the healing process. Rapid treatment response was observed in 275 of 285 wounds, and the magnitude of response was consistently high, with statistically significant outcomes reported for various subgroups.

To examine the internal and external responsiveness of the Pressure Ulcer Scale for Healing (PUSH) tool for assessing the healing progress in acute and chronic wounds. It is important to establish the responsiveness of instruments used in conducting wound care assessments to ensure that they are able to capture changes in wound healing accurately over time. Prospective longitudinal observational study. The key study instrument was the PUSH tool. Internal responsiveness was assessed using paired t-testing and effect size statistics. External responsiveness was assessed using multiple linear regression. All new patients with at least one eligible acute or chronic wound, enrolled in the Nurse and Allied Health Clinic-Wound Care programme between 1 December 2012 - 31 March 2013 were included for analysis (N = 541). Overall, the PUSH tool was able to detect statistically significant changes in wound healing between baseline and discharge. The effect size statistics were large. The internal responsiveness of the PUSH tool was confirmed in patients with a variety of different wound types including venous ulcers, pressure ulcers, neuropathic ulcers, burns and scalds, skin tears, surgical wounds and traumatic wounds. After controlling for age, gender and wound type, subjects in the 'wound improved but not healed' group had a smaller change in PUSH scores than those in the 'wound healed' group. Subjects in the 'wound static or worsened' group had the smallest change in PUSH scores. The external responsiveness was confirmed. The internal and external responsiveness of the PUSH tool confirmed that it can be used to track the healing progress of both acute and chronic wounds. © 2016 The Authors.

Chronic wounds are characterized by a long inflammatory phase that hinders regenerative wound healing. The purpose of this prospective case series was to evaluate how a physiologically relevant concentration of an autologous platelet-rich plasma (PRP) gel affects initial wound healing trajectories of chronic, nonhealing wounds of various etiologies and in different care settings. Using convenience sampling methods, 49 patients (average age: 60.6 years, SD 14.7) with 65 nonhealing wounds (mean duration 47.8 weeks, range 3 to 260) at eight long-term acute care (LTAC) hospitals and three outpatient foot or wound clinics who were prescribed PRP gel for their nonhealing wound were enrolled. The majority of patients had low albumin, hematocrit, and/or hemoglobin levels. After wound assessments and measurements were obtained and the gel prepared, a skin barrier was applied to the periwound skin and the gel applied and protected with cover dressings. The most common wounds were pressure ulcers (n = 21), venous ulcers (n = 16) and diabetic foot ulcers (n = 14). Mean wound area and volume were 19 cm2 (SD 29.4) and 36.2 cm3 (SD 77.7), respectively. Following a mean of 2.8 (SD 2.4) weeks with 3.2 (SD 2.2) applications, reductions in wound volume (mean 51%, SD 43.1), area (39.5%, SD 41.2), undermining (77.8%, SD 28.9), and sinus tract/tunneling (45.8%, SD 40.2) were observed. For all wound etiologies, 97% of wounds improved. The results of this study suggest the application of this PRP gel can reverse nonhealing trends in chronic wounds.

Terminal care is a significant chapter of life in which each individual has the right to expect dignity, compassion, holistic care, and quality of life. The case of 'Sally', a 57-year-old woman with a diagnosis of inflammatory breast cancer, left arm lymphoedema, and a fungating chest wound, gave palliative care nurses a multitude of distressing and complex challenges to manage. Management of lymphoedema is often put into the 'too hard basket', especially in the palliative care setting. Similarly, fungating wounds are hard to confront, and the power of touch is often underestimated. The aim of this case study is to explore and reflect on how these issues entwine, and how vital it is for nurses to feel comfortable in providing the most appropriate care. As a result of reflection on Sally's care management many issues were highlighted, including the crucial need to relieve her symptoms with timely, appropriate, dignified, and respectful care, optimizing her sense of worth and quality of life.

Chronic wounds (ie, wounds that fail to progress through a normal, orderly, timely sequence of repair) continue to pose significant clinical and economic burdens. A prospective, descriptive, 3-week post-marketing surveillance study was conducted across 3 wound care centers in the United States to evaluate the effectiveness of a collagen calcium alginate dressing on chronic wounds in conjunction with standard care (SC) practices (eg, offloading, debridement, compression) to support healing. Eligible participants had to be >18 years of age, have at least 1 chronic wound, and no known sensitivity to collagen. Demographic characteristics were recorded at the screening visit on case report forms. At each visit, wound-related pain was assessed using the Visual Analog Scale along with wound characteristics including size (using digital planimetry), wound exudate (minimal, moderate, heavy), and odor (none, mild). Participants were monitored for adverse events as well as infection based on signs and symptoms in and around the local wound bed, the deeper structures, and the surrounding skin. An intention-to-treat approach was used for all analyses. If an observation was missing, the last observation carried forward principle was used. For wounds that healed, pain and exudate were set to 0 (no pain/exudate) at visit 4. Descriptive, paired t tests and the Wilcoxon signed rank test were used to analyze the data. Of the 31 participants (15 men, 16 women, mean age 66.6 years), most (13, 42%) had a diabetic foot ulcer or venous leg ulcer (10, 32%); median duration of all wounds was 148 days. Thirty (30) patients completed the study. The mean number of comorbidities was 10.6 ± 6.3, and patients used a mean of 9.3 ± 5.64 prescription or over-the-counter medications. For all wounds combined, mean wound area was 4.8 ± 8.38 cm2 at baseline. At week 3, a decrease in wound area of 38.1% was noted (median: 45% ± 42.54; P = .006); 3 wounds healed completely. The change in wound exudate level from visit 1 to visit 4 was statistically significant (P = .006). No adverse events or infections occurred. In this population, the use of etiology-appropriate SC and a collagen calcium alginate dressing resulted in a decrease in wound area after 3 weeks of care. Longer-term studies to confirm these observations and controlled clinical studies to compare the effects of this dressing to other nongauze dressing treatments are needed.

Basic research in plasma medicine has made excellent progress and resulted in the fundamental insights that biological effects of cold atmospheric plasmas (CAP) are significantly caused by changes of the liquid environment of cells, and are dominated by redox-active species. First CAP sources are CE-certified as medical devices. Main focus of plasma application is on wound healing and treatment of infective skin diseases. Clinical applications in this field confirm the supportive effect of cold plasma treatment in acceleration of healing of chronic wounds above all in cases where conventional treatment fails. Cancer treatment is another actual and emerging field of CAP application. The ability of CAP to kill cancer cells by induction of apoptosis has been proved in vitro. First clinical applications of CAP in palliative care of cancer are realized.

Non-healing ulcerative wounds, such as diabetic foot ulcers, are challenging to diagnose and treat due to their numerous possible etiologies and the variable efficacy of advanced wound care products. Thus, there is a critical need to develop new quantitative biomarkers and diagnostic technologies that are sensitive to wound status in order to guide care. The objective of this study was to evaluate the utility of label-free multiphoton microscopy for characterizing wound healing dynamics in vivo and identifying potential differences in diabetic wounds. We isolated and measured an optical redox ratio of FAD/(NADH+FAD) autofluorescence to provide three-dimensional maps of local cellular metabolism. Using a mouse model of wound healing, in vivo imaging at the wound edge identified a significant decrease in the optical redox ratio of the epidermis (p≤0.0103) between Days 3 through 14 compared to Day 1. This decrease in redox ratio coincided with a decrease in NADH fluorescence lifetime and thickening of the epithelium, collectively suggesting a sensitivity to keratinocyte hyperproliferation. In contrast to normal wounds, we have found that keratinocytes from diabetic wounds remain in a proliferative state at later time points with a lower redox ratio at the wound edge. Microstructural organization and composition was also measured from second harmonic generation imaging of collagen and revealed differences between diabetic and non-diabetic wounds. Our work demonstrates label-free multiphoton microscopy offers potential to provide non-invasive structural and functional biomarkers associated with different stages of skin wound healing, which may be used to detect delayed healing and guide treatment.

Tickle, Joy

2015-03-01

The effect of pressure ulcers on patient quality of life have been recognised as a real problem for many years, and the need for robust and effective management of pressure ulcers is now a prominent national health-care issue. Myriad different interventions exist for the treatment of pressure ulcers, including clinically effective dressings and pressure-relieving devices, yet many pressure ulcers still do not heal and often become a chronic wound. This is the second of a series of articles (Norris, 2014) discussing the clinical evaluation of a topical oxygen therapy in practice. It describes a small evaluation involving 18 patients with pressure ulcers. The study set out to determine the effect of a topical oxygen therapy on wound size. The therapy comprises a canister that sprays pure haemoglobin in a water solution into or onto the wound. The haemoglobin spray needs to be used at least once every 3 days, does not require training on its use and can be used in any care setting. Overall, results identified wound healing progression in all 18 wounds and wound size reduction in 17 of the 18 wounds.

Delayed wound healing is a significant clinical problem in patients who have had previous irradiation. This study investigated the effectiveness of Aloe vera (Av) on acute radiation-delayed wound healing. The effect of Av was studied in radiation-exposed rats compared with radiation-only and control rats. Skin wounds were excised on the back of rats after 3 days of local radiation. Wound size was measured on days 0, 3, 6, 9, and 12 after wounding. Wound tissues were examined histologically and the expressions of transforming growth factor β-1 (TGF-β-1) and basic fibroblast growth factor (bFGF) were examined by immunohistochemistry and reverse-transcription polymerase chain reaction. Wound contraction was accelerated significantly by Av on days 6 and 12 after wounding. Furthermore, the inflammatory cell infiltration, fibroblast proliferation, collagen deposition, angiogenesis, and the expression levels of TGF-β-1 and bFGF were significantly higher in the radiation plus Av group compared with the radiation-only group. These data showed the potential application of Av to improve the acute radiation-delayed wound healing by increasing TGF-β-1 and bFGF production. Copyright © 2011 Elsevier Inc. All rights reserved.

The incidence of chronic wounds is increased among older adults, and the impact of chronic wounds on quality of life is particularly profound in this population. It is well established that wound healing slows with age. However, the basic biology underlying chronic wounds and the influence of age-associated changes on wound healing are poorly understood. Most studies have used in vitro approaches and various animal models, but observed changes translate poorly to human healing conditions. The impact of age and accompanying multi-morbidity on the effectiveness of existing and emerging treatment approaches for chronic wounds is also unknown, and older adults tend to be excluded from randomized clinical trials. Poorly defined outcomes and variables, lack of standardization in data collection, and variations in the definition, measurement, and treatment of wounds also hamper clinical studies. The Association of Specialty Professors, in conjunction with the National Institute on Aging and the Wound Healing Society, held a workshop, summarized in this paper, to explore the current state of knowledge and research challenges, engage investigators across disciplines, and identify key research questions to guide future study of age-associated changes in chronic wound healing.

Myofibroblasts after its discovery in 1971 as the principal cell for wound healing has come a long way as far as research is concerned. The primary focus of research has been regarding preventing certain unwanted effects of this cell such as wound contraction and scarring. As far as the oral and maxillofacial region is concerned, the primary concern of this untoward effect is during repair of cleft palate surgically which results impaired development of palate and the dentoalveolar structures. This review focuses on the basic aspects of myofibroblasts such as its origin, formation, function in wound healing, role in wound contraction and ways by which its unwanted effects can be overcome to improve the quality of the post surgical complications of cleft palate surgery.

Electrical Stimulation for Pressure Injuries: A Health Technology Assessment.

PubMed

2017-01-01

Pressure injuries (bedsores) are common and reduce quality of life. They are also costly and difficult to treat. This health technology assessment evaluates the effectiveness, cost-effectiveness, budget impact, and lived experience of adding electrical stimulation to standard wound care for pressure injuries. We conducted a systematic search for studies published to December 7, 2016, limited to randomized and non-randomized controlled trials examining the effectiveness of electrical stimulation plus standard wound care versus standard wound care alone for patients with pressure injuries. We assessed the quality of evidence through Grading of Recommendations Assessment, Development, and Evaluation (GRADE). In addition, we conducted an economic literature review and a budget impact analysis to assess the cost-effectiveness and affordability of electrical stimulation for treatment of pressure ulcers in Ontario. Given uncertainties in clinical evidence and resource use, we did not conduct a primary economic evaluation. Finally, we conducted qualitative interviews with patients and caregivers about their experiences with pressure injuries, currently available treatments, and (if applicable) electrical stimulation. Nine randomized controlled trials and two non-randomized controlled trials were found from the systematic search. There was no significant difference in complete pressure injury healing between adjunct electrical stimulation and standard wound care. There was a significant difference in wound surface area reduction favouring electrical stimulation compared with standard wound care.The only study on cost-effectiveness of electrical stimulation was partially applicable to the patient population of interest. Therefore, the cost-effectiveness of electrical stimulation cannot be determined. We estimate that the cost of publicly funding electrical stimulation for pressure injuries would be $0.77 to $3.85 million yearly for the next 5 years.Patients and caregivers reported that pressure injuries were burdensome and reduced their quality of life. Patients and caregivers also noted that electrical stimulation seemed to reduce the time it took the wounds to heal. While electrical stimulation is safe to use (GRADE quality of evidence: high) there is uncertainty about whether it improves wound healing (GRADE quality of evidence: low). In Ontario, publicly funding electrical stimulation for pressure injuries could result in extra costs of $0.77 to $3.85 million yearly for the next 5 years.

A prospective, randomised, controlled, parallel group, multi-centre clinical trial was conducted at three sites to compare the healing effectiveness of treatment of chronic lower extremity diabetic ulcers with either weekly applications of Apligraf(®) (Organogenesis, Inc., Canton, MA), EpiFix(®) (MiMedx Group, Inc., Marietta, GA), or standard wound care with collagen-alginate dressing. The primary study outcome was the percent change in complete wound healing after 4 and 6 weeks of treatment. Secondary outcomes included percent change in wound area per week, velocity of wound closure and a calculation of the amount and cost of Apligraf or EpiFix used. A total of 65 subjects entered the 2-week run-in period and 60 were randomised (20 per group). The proportion of patients in the EpiFix group achieving complete wound closure within 4 and 6 weeks was 85% and 95%, significantly higher (all adjusted P-values ≤ 0·003) than for patients receiving Apligraf (35% and 45%), or standard care (30% and 35%). After 1 week, wounds treated with EpiFix had reduced in area by 83·5% compared with 53·1% for wounds treated with Apligraf. Median time to healing was significantly faster (all adjusted P-values ≤0·001) with EpiFix (13 days) compared to Apligraf (49 days) or standard care (49 days). The mean number of grafts used and the graft cost per patient were lower in the EpiFix group campared to the Apligraf group, at 2·15 grafts at a cost of $1669 versus 6·2 grafts at a cost of $9216, respectively. The results of this study demonstrate the clinical and resource utilisation superiority of EpiFix compared to Apligraf or standard of care, for the treatment of diabetic ulcers of the lower extremities. © 2014 The Authors.

Chronic wounds are increasing in prevalence and are a costly problem for the US healthcare system and throughout the world. Typically outcomes studies in the field of wound care have been limited to small clinical trials, comparative effectiveness cohorts and attempts to extrapolate results from claims databases. As a result, outcomes in real world clinical settings may differ from these published studies. This study presents a modified intent-to-treat framework for measuring wound outcomes and measures the consistency of population based outcomes across two distinct settings. In this retrospective observational analysis, we describe the largest to date, cohort of patient wound outcomes derived from 626 hospital based clinics and one academic tertiary care clinic. We present the results of a modified intent-to-treat analysis of wound outcomes as well as demographic and descriptive data. After applying the exclusion criteria, the final analytic sample includes the outcomes from 667,291 wounds in the national sample and 1,788 wounds in the academic sample. We found a consistent modified intent to treat healing rate of 74.6% from the 626 clinics and 77.6% in the academic center. We recommend that a standard modified intent to treat healing rate be used to report wound outcomes to allow for consistency and comparability in measurement across providers, payers and healthcare systems. © 2017 by the Wound Healing Society.

African governments are generally plagued with inadequate public health care systems, rapid population growth, low or negative economic growth rates, and shrinking government budgets. How to finance the expansion of health care and improve the quality of services in such a context is one of the most important issues they face. In Guinea-Bissau, the village health post is the most peripheral unit in the health care provider system, offering simple treatments and basic drugs. The system of care at that level is based upon community participation. Villagers provide the necessary materials and labor to build a standard two-room health post, and the government donates materials for windows, door, and hinges, plus simple equipment and an initial stock of drugs estimated to last for six months. The community collects funds to ensure that the initial drug supply is continuously replenished. One or more community members are selected and trained as volunteer village health workers (VHWs) or traditional birth attendants (TBA) in basic training which lasts 15 days, followed by annual 5-day refresher courses. VHWs are educated to treat malaria, diarrhea, conjunctivitis, cough, pain, and wounds, while TBAs are taught how to provide control and prophylaxis during pregnancy, and help in normal child deliveries. By early 1989, 449 units had been established, covering 20-25% of the population, but with large regional variation. This paper reports findings from a three-week field survey conducted in 1989 to gather information on this approach and its potential to mobilize additional resources for the health sector.

Antiphospholipid antibody thrombosis. Another source of chronic wounds.

PubMed

Robertson, Dawna L

2004-01-01

Antiphospholipid antibody thrombosis syndrome is currently not well known and probably underdiagnosed. The risk it presents for recurrent thromboembolism is both life threatening and chronic. Because patients often develop long-standing wounds, it is important for the wound care nurse to identify clients suspect for the disease. Several theories exist speculating on the mechanism of thrombosis involving antiphospholipid antibodies, and each focuses on changes at the interface between the vessel, cell wall membrane, and its interaction with circulating antibodies. As wound care nurses, we should consider antiphospholipid antibody thromboses whenever encountering a recalcitrant wound without obvious underlying cause. Thrombosis can occur anywhere, although 41% of presentations are cutaneous. Recurrent deep vein thrombosis with coexisting venous insufficiency can lead to a missed diagnosis of antiphospholipid thrombosis syndrome, despite evidence of pain and tissue necrosis that is typical of the disease. In any event, long-standing nonhealing wounds are always a signal to revise a diagnosis and seek alternative causes for failure of healing.

Nutrition supplements enriched with immune function enhancing nutrients have been developed to aid wound-healing, although evidence regarding their effectiveness is limited and systematic reviews have lead to inconsistent recommendations. The present pragmatic, randomised, prospective open trial evaluated a wound-specific oral nutrition supplement enriched with arginine, vitamin C and zinc compared to a standard supplement with respect to outcomes in patients with chronic wounds in an acute care setting. Twenty-four patients [11 males and 13 females; mean (SD) age: 67.8 (22.3) years] with chronic wounds (14 diabetic or venous ulcers; 10 pressure ulcers or chronic surgical wounds) were randomised to receive either a wound-specific supplement (n = 12) or standard supplement (n = 12) for 4 weeks, with ongoing best wound and nutrition care for an additional 4 weeks. At baseline, and at 4 and 8 weeks, the rate of wound-healing, nutritional status, protein and energy intake, quality of life and product satisfaction were measured. Linear mixed effects modelling with random intercepts and slopes were fitted to determine whether the wound-specific nutritional supplement had any effect. There was a significant improvement in wound-healing in patients receiving the standard nutrition supplement compared to a wound-specific supplement (P = 0.044), although there was no effect on nutritional status, dietary intake, quality of life and patient satisfaction. The results of the present study indicate that a standard oral nutrition supplement may be more effective at wound-healing than a specialised wound supplement in this clinical setting. © 2013 The Authors Journal of Human Nutrition and Dietetics © 2013 The British Dietetic Association Ltd.

The objective of the study was to observe the effects of tissue-engineered skin in combination with platelet-rich plasma (PRP) and other preparations on the repair of large skin wound on nude mice.We first prepared PRP from venous blood by density-gradient centrifugation. Large skin wounds were created surgically on the dorsal part of nude mice. The wounds were then treated with either artificial skin, tissue-engineered skin, tissue-engineered skin combined with basic fibroblast growth factor, tissue-engineered skin combined with epidermal growth factor, or tissue-engineered skin combined with PRP. Tissue specimens were collected at different time intervals after surgery. Hematoxylin-eosin and periodic acid-Schiff staining and immunohistochemistry were performed to assess the rate of wound healing.Macroscopic observations, hematoxylin-eosin/periodic acid-Schiff staining, and immunohistochemistry revealed that the wounds treated with tissue-engineered skin in combination with PRP showed the most satisfactory wound recovery, among the 5 groups.

A Formidable Foe is Sabotaging Your Results: What You Should Know about Biofilms and Wound Healing

Learning Objectives After reading this article, the participant should be able to: 1. Describe biofilm pathogenesis as it relates to problem wounds, 2. Understand the pre-clinical and clinical evidence implicating biofilm in problem wounds, 3. Explain the diagnostic and treatment challenges that biofilms create for problem wounds, 4. Demonstrate a basic understanding of emerging strategies aimed at counteracting these processes. Summary Biofilm represents a protected mode of growth for bacteria, allowing them to evade standard diagnostic techniques and avoid eradication by standard therapies. Though only recently discovered, biofilm has existed for millennia and complicates nearly every aspect of medicine. Biofilm impacts wound healing by allowing bacteria to evade immune responses, prolonging inflammation and disabling skin barrier function. It is important to understand why problem wounds persist despite state-of-the-art treatment, why they are difficult to accurately diagnose, and why they recur. The aim of this article is to focus on current gaps in knowledge related to problem wounds, specifically, biofilm infection. PMID:28445380

The increasingly aged population worldwide means more people are living with chronic diseases, reduced autonomy, and taking various medications. Health professionals should take these into consideration when managing dermatological problems in elderly patients. Accordingly, current research is investigating the dermatological problems associated with the loss of cutaneous function with age. As cell renewal slows, the physical and chemical barrier function declines, cutaneous permeability increases, and the skin becomes increasingly vulnerable to external factors. In geriatric dermatology, the consequences of cutaneous aging lead to xerosis, skin folding, moisture-associated skin damage, and impaired wound healing. These problems pose significant challenges for both the elderly and their carers. Most often, nurses manage skin care in the elderly. However, until recently, little attention has been paid to developing appropriate, evidence-based, skincare protocols. The objective of this paper is to highlight common clinical problems with aging skin and provide some appropriate advice on cosmetic protocols for managing them. A review of the literature from 2004 to 2014 using PubMed was performed by a working group of six European dermatologists with clinical and research experience in dermatology. Basic topical therapy can restore and protect skin barrier function, which relieves problems associated with xerosis, prevents aggravating moisture-associated skin damage, and enhances quality of life. In conclusion, the authors provide physicians with practical recommendations to assist them in implementing basic skin care for the elderly in an integrated care approach. PMID:26929610

Wound matrix materials are used to improve the regeneration of dermal and epidermal layers in both acute and chronic wounds. Contemporary wound matrices are primarily composed of biologic materials such as processed xenogeneic and allogeneic tissues. Unfortunately, existing biologic wound matrices possess multiple limitations including poor longevity, durability, strength, and enzymatic resistance required for persistent support for new tissue formation. A fully-synthetic, resorbable electrospun material (Restrata Wound Matrix, Acera, St.Louis, Missouri ) that exhibits structural similarities to the native extracellular matrix offers a new approach to the treatment of acute and chronic wounds. This novel matrix is the first product to combine the advantages of synthetic construction (e.g. resistance to enzymatic degradation, excellent biocompatibility, strength/durability and controlled degradation) with the positive attributes of biologic materials (e.g. biomimetic architecture similar to human extracellular matrix (ECM), fibrous architecture optimized to support cellular migration and proliferation, engineered porosity to encourage tissue ingrowth and vascularization). These features allow RWM to achieve rapid and complete healing of full-thickness wounds that, in preclinical studies, is comparable to Integra Bilayer Wound Matrix (Integra LifeSciences, Plainsboro, New Jersey), a gold standard biologic material with diverse clinical indications in the wound care. Together, this review suggests that the RWM offers a unique fully-synthetic alternative to existing biologic matrices that is effective, widely available, easy to store, simple to apply and low cost.

Our previous studies demonstrated that human bone marrow-derived mesenchymal stromal cells have great potential for wound healing. However, it is difficult to clinically utilize cultured stem cells. Recently, human umbilical cord blood-derived mesenchymal stromal cells (hUCB-MSCs) have been commercialized for cartilage repair as a first cell therapy product that uses allogeneic stem cells. Should hUCB-MSCs have a superior effect on wound healing as compared with fibroblasts, which are the main cell source in current cell therapy products for wound healing, they may possibly replace fibroblasts. The purpose of this in vitro study was to compare the wound-healing activity of hUCB-MSCs with that of fibroblasts. This study was particularly designed to compare the effect of hUCB-MSCs on diabetic wound healing with those of allogeneic and autologous fibroblasts. Healthy (n = 5) and diabetic (n = 5) fibroblasts were used as the representatives of allogeneic and autologous fibroblasts for diabetic patients in the control group. Human UCB-MSCs (n = 5) were used in the experimental group. Cell proliferation, collagen synthesis and growth factor (basic fibroblast growth factor, vascular endothelial growth factor and transforming growth factor-β) production were compared among the three cell groups. Human UCB-MSCs produced significantly higher amounts of vascular endothelial growth factor and basic fibroblast growth factor when compared with both fibroblast groups. Human UCB-MSCs were superior to diabetic fibroblasts but not to healthy fibroblasts in collagen synthesis. There were no significant differences in cell proliferation and transforming growth factor-β production. Human UCB-MSCs may have greater capacity for diabetic wound healing than allogeneic or autologous fibroblasts, especially in angiogenesis. Copyright © 2015 International Society for Cellular Therapy.

The purpose of this study was to compare the effect of standard wound care with adjunctive hyperbaric oxygen therapy (HBOT) to standard wound care alone on wound healing, markers of inflammation, glycemic control, amputation rate, survival rate of tissue, and health-related quality of life in patients with diabetic foot ulcers (DFUs). Prospective, randomized, open-label, controlled study. The sample comprised 38 patients with nonhealing DFUs who were deemed poor candidates for vascular surgery. Subjects were randomly allocated to an experimental group (standard care plus HBOT, n = 20) or a control group (standard care alone, n = 18). The study setting was a medical center in Kaohsiung City, Taiwan. Hyperbaric oxygen therapy was administered in a hyperbaric chamber under 2.5 absolute atmospheric pressure for 120 minutes; subjects were treated 5 days a week for 4 consecutive weeks. Both groups received standard wound care including debridement of necrotic tissue, topical therapy for Wagner grade 2 DFUs, dietary control and pharmacotherapy to maintain optimal blood glucose levels. Wound physiological indices were measured and blood tests (eg, markers of inflammation) were undertaken. Health-related quality of life was measured using the Medical Outcomes Study 36-Item Short Form. Complete DFU closure was achieved in 5 patients (25%) in the HBOT group (n = 20) versus 1 participant (5.5%) in the routine care group (n = 18) (P = .001). The amputation rate was 5% for the HBOT group and 11% for the routine care group (χ = 15.204, P = .010). The HBOT group showed statistically significant improvements in inflammation index, blood flow, and health-related quality of life from pretreatment to 2 weeks after the last therapy ended (P < .05). Hemoglobin A1c was significantly lower in the HBOT group following treatment (P < .05) but not in the routine care group. Adjunctive HBOT improved wound healing in persons with DFU. Therapy also reduced the risk of amputation of the affected limb. We assert that at least 20 HBOT sessions are required to be effective.

Diabetic foot wounds: the value of negative pressure wound therapy with instillation.

Dalla Paola, Luca

2013-12-01

Chronic wounds such as diabetic foot wounds are a tremendous burden to the health care system and often require a multidisciplinary approach to prevent amputations. Advanced technologies such as negative pressure wound therapy (NPWT) and bioengineered tissues have been successfully used in the treatment of these types of complex wounds. However, the introduction of NPWT with instillation (NPWTi) has provided an alternative treatment for treating complex and difficult-to-heal wounds. This article provides an overview of NPWT and the new NPWTi system and describes preliminary experience using NPWTi on patients with complicated infected diabetic foot wounds after surgical debridement and in a multidisciplinary setting. © 2013 The Author.

Telemedicine in wound healing.

PubMed

Jones, Sophie M; Banwell, Paul E; Shakespeare, Peter G

2004-12-01

Better care for patients and improved health care depends on the availability of good information which is accessible when and where it is needed. The development of technology, more specifically the Internet, has expanded the means whereby information can be acquired and transmitted over large distances enabling the concept of telemedicine to become a reality. Telemedicine, defined as the practise of medicine at a distance, encompasses diagnosis, education and treatment. It is a technology that many thought would expand rapidly and change the face of medicine. However, this has not happened and during the last decade although certain telemedicine applications, such as video-consulting and teleradiology, have matured to become essential health care services in some countries, others, such as telepathology, remain the subject of intensive research effort. Telemedicine can be used in almost any medical specialty although the specialties best suited are those with a high visual component. Wound healing and wound management is thus a prime candidate for telemedicine. Development of a suitable telemedical system in this field could have a significant effect on wound care in the community, tertiary referral patterns and hospital admission rates.

Wound fluids: a reflection of the state of healing.

Analyzing acute and chronic wound fluids provides an important and intriguing insight into the wound milieu. This review outlines some of the salient features of wound repair and the wound fluid environment. Most studies support the premise that the contents of the wound fluid reflect the status of the wound and can be indicative of whether a wound is on the course of a normal or impaired response to injury. For example, chronic wound fluids often differ from acute wound fluids in their proliferative effects on cells active in healing as well as their proteolytic effects. The authors discuss various cytokines, growth factors, proteinases, and protease inhibitors within wound fluids as well as their effect on wound repair. This review also presents confounding factors affecting interpretation of wound fluid studies, suggesting that further studies need to elucidate mechanisms whereby wound fluids either enhance or inhibit wound repair. So far, wound fluid analysis has yielded tantalizing glimpses of the teeming wound environment. What wound fluid contents tell us about the wound or its clinical care is not yet certain.

To evaluate the implementation of the Champions for Skin Integrity model on facilitating uptake of evidence-based wound management and improving skin integrity in residents of aged care facilities. The incidence of skin tears, pressure injuries and leg ulcers increases with age, and such wounds can be a serious issue in aged care facilities. Older adults are not only at higher risk for wounds related to chronic disease but also injuries related to falls and manual handling requirements. A longitudinal, pre-post design. The Champions for Skin Integrity model was developed using evidence-based strategies for transfer of evidence into practice. Data were collected before and six months after implementation of the model. Data on wound management and skin integrity were obtained from two random samples of residents (n = 200 pre; n = 201 post) from seven aged care facilities. A staff survey was also undertaken (n = 126 pre; n = 143 post) of experience, knowledge and evidence-based wound management. Descriptive statistics were calculated for all variables. Where relevant, chi-square for independence or t-tests were used to identify differences between the pre-/postdata. There was a significant decrease in the number of residents with a wound of any type (54% pre vs 43% post, χ 2 4·2, p = 0·041), as well as a significant reduction in specific wound types, for example pressure injuries (24% pre vs 10% post, χ 2 14·1, p < 0·001), following implementation of the model. An increase in implementation of evidence-based wound management and prevention strategies was observed in the postimplementation sample in comparison with the preimplementation sample. This included use of limb protectors and/or protective clothing 6% pre vs 20% post (χ 2 17·0, p < 0·001) and use of an emollient or soap alternative for bathing residents (50% pre vs 74% post, χ 2 13·9, p = 0·001). Implementation of the model in this sample fostered an increase in implementation of evidence-based wound management and prevention strategies, which was associated with a decrease in the prevalence and severity of wounds. This study suggests the Champions for Skin Integrity model has the potential to improve uptake of evidence-based wound management and improve skin integrity for older adults. © 2017 John Wiley & Sons Ltd.

To observe the effects of artificial dermis combined with basic fibroblast growth factor (bFGF) on the treatment of cicatrix and deep skin wounds. The clinical data of 72 patients with wounds repaired with artificial dermis, hospitalized in our unit from October 2010 to April 2015, conforming to the study criteria, were retrospectively analyzed. The types of wounds were wounds after resection of cicatrices, deep burn wounds without exposure of tendon or bone, and wounds with exposure of small area of tendon or bone, in a total number of 102. Wounds were divided into artificial dermis group (A, n=60) and artificial dermis+ bFGF group (B, n=42) according to whether or not artificial dermis combined with bFGF. In group A, after release and resection of cicatrices or thorough debridement of deep skin wounds, artificial dermis was directly grafted to wounds in the first stage operation. After complete vascularization of artificial dermis, wounds were repaired with autologous split-thickness skin grafts in the second stage operation. In group B, all the procedures were exactly the same as those in group A except that artificial dermis had been soaked in bFGF for 30 min before grafting. Operation area, complete vascularization time of artificial dermis, survival of skin grafts, and the follow-up condition of wounds in the two groups were recorded. Data were processed with t test and Fisher's exact test. (1) Operation areas of wounds after resection of cicatrices, deep burn wounds without exposure of tendon or bone, and wounds with exposure of small area of tendon or bone in the two groups were about the same (with t values from -1.853 to -0.200, P values above 0.05). Complete vascularization time of artificial dermis in wounds after resection of cicatrices, deep burn wounds without exposure of tendon or bone, and wounds with exposure of small area of tendon or bone in group B were respectively (15.6 ± 2.9), (14.7 ± 2.7), and (20.3 ± 4.4) d, and they were shorter by an average time of 2.7, 4.0, 7.4 d, respectively, as compared with those in corresponding types of wounds in group A [respectively (18.3 ± 4.7), (18.7 ± 4.2), and (27.7 ± 8.8) d, with t values from -2.779 to -2.383, P values below 0.05]. (2) The ratio of skin grafts with excellent survival in the three types of wounds in group B were higher than those in corresponding types of wounds in group A, but there were no statistically significant differences (with P values above 0.05). (3) Patients were followed up for 1 to 48 months, and there were no obvious cicatrices in skin graft sites and the donor sites during the following time. Artificial dermis combined with bFGF can effectively shorten the vascularization time of artificial dermis in wounds after resection of cicatrices and deep skin wounds.

Atypical ulcers: wound biopsy results from a university wound pathology service .

Chronic wounds are an increasing health burden across the continuum of care and encountered by a wide variety of healthcare providers and physicians of all specialties. The majority of chronic wounds are caused by vascular insufficiency, neuropathy, or prolonged pressure. Wounds caused by other underlying health conditions or external factors such as radiation or spider bites are usually referred to as atypical. Although a wound biopsy generally is recommended in the case of refractory, nonhealing ulcers or when wounds present with atypical signs and symptoms, little is known about the distribution of atypical ulcers. A retrospective, descriptive study was conducted to describe the proportion and differential diagnosis of atypical ulcer biopsies received during a 2-year period by the wound pathology division in the division of Dermatopathology at the University of Miami Department of Dermatology and Cutaneous Surgery. Of the 350 wound biopsies received for diagnostic purposes, 104 (29.7%) were due to atypical causes. The majority of specimens were neoplasms (n = 24). Pyoderma gangrenosum was the most common atypical diagnosis encountered (n = 14). Vasculitis, predominantly leukocytoclastic vasculitis, and external causes were diagnosed in 16 and 15 biopsies, respectively. This study represents the first published case series of atypical ulcer biopsy results from a wound pathology division. Although the prevalence results cannot be generalized and are likely lower in the general population of patients with nonhealing wounds, the results confirm the usefulness of obtaining wound biopsies to provide a definitive diagnosis and to guide care.

The purpose of this retrospective registry data analysis was to explore the effectiveness of a novel multivalent topical ointment (Terrasil Infection Control Wound Care Ointment; Aspiera Medical, Woonsocket, Rhode Island), containing a patented mineral complex and 0.2% benzethonium chloride in the treatment of nonhealing acute and chronic wounds. Aspiera Medical designed a registry to capture physician experiences and treatment results with Terrasil Infection Control Wound Care Ointment. Physicians were asked to enter deidentified patient data into an online registry. Wound clinics in the United States were asked to participate in the registry. Physicians at 4 wound clinics treated 30 patients (26 of whom completed the treatment) with various chronic wounds that had persisted for an average of 6 months and entered treatment data into the registry. Patients applied the ointment according to physician orders. Concurrent treatments used by patients included offloading, compression wraps, and dressings, such as collagen and calcium alginate. Patients were treated until complete wound closure or lost to follow-up. Physicians calculated each patient's percentage wound reduction at each visit. Thirty patients were entered into the registry. Pretreatment and posttreatment measurements were available for 26 of them. Patients achieved an average surface area reduction of 84% in a mean of 23 days' treatment. The antimicrobial and moisturizing ointment studied appears to be effective in promoting wound closure in a variety of acute and chronic wounds. Wounds studied included diabetic foot ulcers, venous leg ulcers, venous stasis ulcers, surgical infections, burns, and insect bites. The results of this registry data analysis will be used to inform planned clinical trials.

Evidence review: the clinical benefits of Safetac technology in wound care.

PubMed

Davies, Phil; Rippon, Mark

2008-11-01

Common causes of trauma and wound pain include: the removal of dressings that become stuck to the wound bed; skin stripping of peri-wound skin, as a result of the repeated application and removal of adhesive dressings; and tissue excoriation and maceration of the peri-wound skin, due to inadequate management of wound exudate. This supplement outlines how dressings with Safetac adhesive technology can help clinicians to avoid these problems. A review of the clinical and scientific evidence relating to dressings with Safetac clearly demonstrates that they can be used to prevent trauma and minimise pain on a wide range of wound types and skin injuries.

The profile of wounding in civilian public mass shooting fatalities.

Smith, Edward Reed; Shapiro, Geoff; Sarani, Babak

2016-07-01

The incidence and severity of civilian public mass shootings (CPMS) continue to rise. Initiatives predicated on lessons learned from military woundings have placed strong emphasis on hemorrhage control, especially via use of tourniquets, as means to improve survival. We hypothesize that both the overall wounding pattern and the specific fatal wounds in CPMS events are different from those in military combat fatalities and thus may require a new management strategy. A retrospective study of autopsy reports for all victims involved in 12 CPMS events was performed. Civilian public mass shootings was defined using the FBI and the Congressional Research Service definition. The site of injury, probable site of fatal injury, and presence of potentially survivable injury (defined as survival if prehospital care is provided within 10 minutes and trauma center care within 60 minutes of injury) was determined independently by each author. A total 139 fatalities consisting of 371 wounds from 12 CPMS events were reviewed. All wounds were due to gunshots. Victims had an average of 2.7 gunshots. Relative to military reports, the case fatality rate was significantly higher, and incidence of potentially survivable injuries was significantly lower. Overall, 58% of victims had gunshots to the head and chest, and only 20% had extremity wounds. The probable site of fatal wounding was the head or chest in 77% of cases. Only 7% of victims had potentially survivable wounds. The most common site of potentially survivable injury was the chest (89%). No head injury was potentially survivable. There were no deaths due to exsanguination from an extremity. The overall and fatal wounding patterns following CPMS are different from those resulting from combat operations. Given that no deaths were due to extremity hemorrhage, a treatment strategy that goes beyond use of tourniquets is needed to rescue the few victims with potentially survivable injuries.

Chronic wounds represent a significant burden to patients, health care professionals, and health care systems, affecting over 40 million patients and creating costs of approximately 40 billion € annually. We will present a medical device for photo-stimulated wound care based on a wearable large area flexible and disposable light management system consisting of a waveguide with incorporated micro- and nanometer scale optical structures for efficient light in-coupling, waveguiding and homogeneous illumination of large area wounds. The working principle of this innovative device is based on the therapeutic effects of visible light to facilitate the self-healing process of chronic wounds. On the one hand, light exposure in the red (656nm) induces growth of keratinocytes and fibroblasts in deeper layers of the skin. On the other hand, blue light (453nm) is known to have antibacterial effects predominately at the surface layers of the skin. In order to be compliant with medical requirements the system will consist of two elements: a disposable wound dressing with embedded flexible optical waveguides for the light management and illumination of the wound area, and a non-disposable compact module containing the light sources, a controller, a rechargeable battery, and a data transmission unit. In particular, we will report on the developed light management system. Finally, as a proof-of-concept, a demonstrator will be presented and its performances will be reported to demonstrate the potential of this innovative device.

The costs and outcomes of treating a deep pressure ulcer in a patient with quadriplegia .

 The cost of pressure ulcers, especially Stage III and Stage IV ulcers, is substantial. A 27-year-old man with a 6-year history of quadriplegia developed an ischial pressure ulcer. Twelve months of treatment with wet-to-dry dressings were followed by admission to several facilities and 15 months of care with biological dressings and negative pressure wound therapy (NPWT). When admitted to the authors' wound care center, the wound measured 4.5 cm x 3.2 cm with exposed bone. A review of his insurance records showed that paid claims totaled $242,350, including $52,992 for NPWT rental costs. The patient was considered a good candidate for minimally invasive surgical intervention with external tissue expanders. Following a 14-day course of antibiotics to treat his infection, the wound was debrided and the tissue expanders applied. After 16 days, the wound was closed. The patient returned to work 6 weeks after the procedure. At the 23-month follow-up, the wound remained closed. Insurance payments for the care that resulted in wound closure totaled $43,814. This case study illustrates the potential of the external tissue expansion technique to close deep pressure ulcers within a relatively short amount of time at comparatively lower cost. Studies including control treatments are needed to confirm these conclusions.

Medical simulation: Overview, and application to wound modelling and management

Pai, Dinker R.; Singh, Simerjit

2012-01-01

Simulation in medical education is progressing in leaps and bounds. The need for simulation in medical education and training is increasing because of a) overall increase in the number of medical students vis-à-vis the availability of patients; b) increasing awareness among patients of their rights and consequent increase in litigations and c) tremendous improvement in simulation technology which makes simulation more and more realistic. Simulation in wound care can be divided into use of simulation in wound modelling (to test the effect of projectiles on the body) and simulation for training in wound management. Though this science is still in its infancy, more and more researchers are now devising both low-technology and high-technology (virtual reality) simulators in this field. It is believed that simulator training will eventually translate into better wound care in real patients, though this will be the subject of further research. PMID:23162218

The knowledge of wound ballistics and of wounding mechanisms is mandatory for the radiologist to interpret the CT findings of gunshot wounds. The severity of a bullet wound depends on the characteristics of the tissue it goes through, i.e., tissue elasticity, density, thickness of the wounded body part, the type of tissue, its specific gravity, internal cohesiveness and anatomical relationships, as well as on missile characteristics, i.e., mass, shape, fragmentation and deformation. Bullet velocity is certainly a major factor in wounding, but it is only one factor. Two major wounding mechanisms exist the crushing of the bullet-struck tissue (forming the permanent cavity) and radial stretching (forming a temporary cavity). Bullet "yaw" is defined as the angle between the long axis of the bullet and its flight path. The yaw is directly proportional to tissue crushing and stretching: the wider the yaw, the most severe tissue crushing and stretching and, therefore, the more severe tissue damage. The basic knowledge of these concepts is of the utmost importance to understand the CT findings of gunshot wounds and can help physicians study and treat gunshot wounds.

Mesenchymal Stem Cells in Chronic Wounds: The Spectrum from Basic to Advanced Therapy

PubMed Central

Otero-Viñas, Marta; Falanga, Vincent

2016-01-01

Significance: Almost 7 million Americans have chronic cutaneous wounds and billions of dollars are spent on their treatment. The number of patients with nonhealing wounds keeps increasing worldwide due to an ever-aging population, increasing number of obese and diabetic patients, and cardiovascular disease. Recent Advances: Advanced treatments for difficult wounds are needed. Therapy with mesenchymal stem cells (MSCs) is attractive due to their differentiating potential, their immunomodulating properties, and their paracrine effects. Critical Issues: New technologies (including growth factors and skin substitutes) are now widely used for stimulating wound healing. However, in spite of these advances, the percentage of complete wound closure in most clinical situations is around 50–60%. Moreover, there is a high rate of wound recurrence. Future Directions: Recently, it has been demonstrated that MSCs speed up wound healing by decreasing inflammation, by promoting angiogenesis, and by decreasing scarring. However, there are some potential limitations to successful MSC therapy. These limitations include the need to improve cell delivery methods, cell viability, heterogeneity in MSC preparations, and suboptimal wound bed preparation. Further large, controlled clinical trials are needed to establish the safety of MSCs before widespread clinical application. PMID:27076993

Negative pressure wound therapy combined with acoustic pressure wound therapy for infected post surgery wounds: a case series.

2008-09-01

Acute infection of surgical incision sites often requires specialized wound care in preparation for surgical closure. Optimal therapy for preparing such wounds for a secondary closure procedure remains uncertain. The authors report wound outcomes after administering acoustic pressure wound therapy in conjunction with negative pressure wound therapy with reticulated open-cell foam dressing changes to assist with bacteria removal from open, infected surgical-incision sites in preparation for secondary surgical closure in three patients. Before incorporating acoustic pressure wound therapy at the authors' facility, the average negative pressure wound therapy with reticulated open-cell foam dressing course prior to secondary surgical closure was 30 days; with its addition, two of three patients underwent successful surgical closure with no postoperative complications after 21 and 14 days, respectively; one patient succumbed to nonwound-related complications before wound closure. Larger, prospective studies are needed to evaluate combining negative pressure wound therapy with reticulated open-cell foam dressing and acoustic pressure wound therapy for infected, acute post surgery wounds.

With the growing demand for more efficient wound care after surgery, there is a necessity to develop a machine learning based image analysis approach to reduce the burden for health care professionals. The aim of this study was to propose a novel approach to recognize wound infection on the postsurgical site. Firstly, we proposed an optimal clustering method based on unimodal-rosin threshold algorithm to extract the feature points from a potential wound area into clusters for regions of interest (ROI). Each ROI was regarded as a suture site of the wound area. The automatic infection interpretation based on the support vector machine is available to assist physicians doing decision-making in clinical practice. According to clinical physicians' judgment criteria and the international guidelines for wound infection interpretation, we defined infection detector modules as the following: (1) Swelling Detector, (2) Blood Region Detector, (3) Infected Detector, and (4) Tissue Necrosis Detector. To validate the capability of the proposed system, a retrospective study using the confirmation wound pictures that were used for diagnosis by surgical physicians as the gold standard was conducted to verify the classification models. Currently, through cross validation of 42 wound images, our classifiers achieved 95.23% accuracy, 93.33% sensitivity, 100% specificity, and 100% positive predictive value. We believe this ability could help medical practitioners in decision making in clinical practice.

This article is in two parts. The overall aim of this section was to review the literature in relation to pilonidal sinus wounds (PSW) healing by secondary intent for a Master's of Science in Wound Healing and Tissue Repair thesis. The purpose of the literature review was to determine if an evidence-based guideline or consensus document existed for the care of these wounds, and if not, to determine the topics from which to develop items for the first round of a modified reactive Delphi questionnaire. Part two will describe the iterative process, the analysis and the results. The review found no best practice guidelines concerning PSW, and only one clinical pathway. Seventeen areas of interest were identified that may contribute to optimal healing conditions or to delayed healing. These included microbiology of infected PSW, signs and symptoms of localised or deeper (spreading) chronic wound infection, swab for c&s, role of topical antiseptics or antimicrobials, systemic antibiotics, local wound interventions, optimal positioning, wound cleansing, principles of moist wound healing/dressing selection, topical negative pressure (TNP) therapy, peri-wound skin decontamination and depilation, pain control, physical activities, optimal nutrition and patient education. © 2011 The Authors. © 2011 Blackwell Publishing Ltd and Medicalhelplines.com Inc.

Retrospective clinical evaluation of gauze-based negative pressure wound therapy.

Negative pressure wound therapy (NPWT) is an established modality in the treatment of challenging wounds. However, most existing clinical evidence is derived from the use of open-cell polyurethane foam at -125 mmHg. Alternative negative pressure systems are becoming available, which use gauze at a pressure of -80 mmHg. This study describes clinical results from a retrospective non comparative analysis of 30 patients treated with Chariker-Jeter gauze-based negative pressure systems (V1STA, Versatile-1 and EZ-Care; Smith & Nephew, Inc.) in a long-term care setting. The mean age of the patients was 72 years. The wounds consisted of chronic (n = 11), surgical dehiscence (n = 11) and surgical incision (n = 8). Wound volume and area were recorded at commencement and at the cessation of therapy. Discontinuation of therapy was instigated upon closure through secondary intention or when size and exudate were sufficiently reduced that the wounds could be managed by conventional wound dressing (median 41 days). An overall median reduction in wound volume of 88.0% (P < 0.001) and a 68.0% reduction in area (P < 0.001) compared with baseline were observed over the course of NPWT. The overall rate of volume reduction (15.1% per week) compares favourably with published data from foam-based systems.

Quantitative wound healing measurement and monitoring system based on an innovative 3D imaging system

2011-03-01

In this paper, we report a novel three-dimensional (3D) wound imaging system (hardware and software) under development at Technest Inc. System design is aimed to perform accurate 3D measurement and modeling of a wound and track its healing status over time. Accurate measurement and tracking of wound healing enables physicians to assess, document, improve, and individualize the treatment plan given to each wound patient. In current wound care practices, physicians often visually inspect or roughly measure the wound to evaluate the healing status. This is not an optimal practice since human vision lacks precision and consistency. In addition, quantifying slow or subtle changes through perception is very difficult. As a result, an instrument that quantifies both skin color and geometric shape variations would be particularly useful in helping clinicians to assess healing status and judge the effect of hyperemia, hematoma, local inflammation, secondary infection, and tissue necrosis. Once fully developed, our 3D imaging system will have several unique advantages over traditional methods for monitoring wound care: (a) Non-contact measurement; (b) Fast and easy to use; (c) up to 50 micron measurement accuracy; (d) 2D/3D Quantitative measurements;(e) A handheld device; and (f) Reasonable cost (< $1,000).

It was previously shown that human adipose-derived stromal cell (hADSC)-conditioned medium (CM) promotes wound healing. An essential part of the wound healing process is neovascularization in the wound bed. We hypothesized that CM prepared from hADSCs cultured as spheroids in three-dimensional suspension bioreactors (spheroid CM) would contain much higher concentrations of angiogenic growth factors secreted by hADSCs, induce a higher extent of neovascularization in the wound bed, and improve wound healing as compared with CM prepared by conventional monolayer culture (monolayer CM). The concentrations of angiogenic growth factors (i.e., vascular endothelial growth factor, basic fibroblast growth factor, and hepatocyte growth factor) in spheroid CM were 20- to 145-fold higher than those in monolayer CM. Either fresh medium, monolayer CM, or spheroid CM was administered to full-thickness wounds created on the dorsal aspects of athymic mice. The monolayer CM promoted wound healing as compared with fresh medium or no treatment. Importantly, wound closure was faster, and dermal and epidermal regeneration was improved in the spheroid CM-treated mice compared with that in the monolayer CM-treated mice. The improved wound healing by spheroid CM may be attributed, at least in part, to enhanced neovascularization in the wound beds. The spheroid-based CM approach showed potential as a therapy for skin wound repair. Copyright © 2015 Elsevier Inc. All rights reserved.

Complicated and long-lasting wound care of diabetic foot ulcers are moving from specialists in wound care at hospitals towards community nurses without specialist diabetic foot ulcer wound care knowledge. The aim of the study is to elucidate community nurses' professional basis for treating diabetic foot ulcers. A situational case study design was adopted in an archetypical Danish community nursing setting. Experience is a crucial component in the community nurses' professional basis for treating diabetic foot ulcers. Peer-to-peer training is the prevailing way to learn about diabetic foot ulcer, however, this contributes to the risk of low evidence-based practice. Finally, a frequent behaviour among the community nurses is to consult colleagues before treating the diabetic foot ulcers.

Epidermal grafting versus split-thickness skin grafting for wound healing (EPIGRAAFT): study protocol for a randomised controlled trial.

Split-thickness skin grafting (SSG) is an important modality for wound closure. However, the donor site becomes a second, often painful wound, which may take more time to heal than the graft site itself and holds the risk of infection and scarring. Epidermal grafting (EG) is an alternative method of autologous skin grafting that harvests only the epidermal layer of the skin by applying continuous negative pressure on the normal skin to raise blisters. This procedure has minimal donor site morbidity and is relatively pain-free, allowing autologous skin grafting in an outpatient setting. We plan to compare EG to SSG and to further investigate the cellular mechanism by which each technique achieves wound healing. EPIGRAAFT is a multicentre, randomised, controlled trial that compares the efficacy and wound-healing mechanism of EG with SSG for wound healing. The primary outcome measures are the proportion of wounds healed in 6 weeks and the donor site healing time. The secondary outcome measures include the mean time for complete wound healing, pain score, patient satisfaction, health care utilisation, cost analysis, and incidence of adverse events. This study is expected to define the efficacy of EG and promote further understanding of the mechanism of wound healing by EG compared to SSG. The results of this study can be used to inform the current best practise for wound care. Clinicaltrials.gov identifier, NCT02535481 . Registered on 11 August 2015.

To evaluate the influence of different methods of local treatment on tissue repair in patients with diabetic foot ulcers. We evaluated such clinical characteristics as wound size and local perfusion after using negative pressure wound therapy (NPWT), local collagen, and standard care in patients with diabetic foot ulcers. We observed 63 patients with neuropathic and neuroischemic forms of diabetic foot (without critical ischemia) after surgical debridement. After that 21 patients received NPWT, 21 local collagen treatment and 21 ― standard care. After using NPWT wound area and depth decreased in 19,8% and 42,8% (p<0.05), in group of collagen dressings in 26,4 and 30,4% (p<0.05). In control group those parameters were 17,0 и 16.6% respectively (p<0.05). There was found the significant increase of local perfusion according to oxygen monitoring in group of NPWT (p<0.05). The received data showed that the intensity of lower limb tissue repair processes increases more significant after using NPWT and collagen dressings in comparison to standard care which is found according to wound size and tissue perfusion alterations.

There are an increasing number of wound closure materials and suturing techniques described in the dermatologic and surgery literature. A dermatologic surgeon's familiarity with these materials and techniques is important to supplement his or her already established practices and improve surgical outcomes. To perform a thorough literature review of wound closure materials (sutures, tissue adhesives, surgical tape, and staples) and suturing techniques and to outline how and when to use them. A literature review was conducted using PubMed and other online search engines. Keywords searched included suture, tissue adhesive, tissue glue, surgical tape, staples, dermatologic suturing, and suturing techniques. Numerous articles outline the utility of various sutures, surgical adhesives, surgical tape, and staples in dermatologic surgery. In addition, there are various articles describing classic and novel suturing techniques along with their specific uses in cutaneous surgery. Numerous factors must be considered when choosing a wound closure material and suturing technique. These include wound tension, desire for wound edge eversion/inversion, desired hemostasis, repair type, patient's ability to care for the wound and return for suture removal, skin integrity, and wound location. Careful consideration of these factors and proper execution of suturing techniques can lead to excellent cosmetic results.

Patients with diabetic foot ulcers (DFU) have an increased risk of lower extremity amputation. A retrospective chart review of patients with DFUs attending the Foot Treatment and Assessment chiropodist-led outpatient clinic at an inner-city academic hospital was conducted to determine wound healing outcomes and characteristics contributing to outcomes. We reviewed the complete clinical history of 279 patients with 332 DFUs spanning over a five-year period. The mean age of patients was 61.5±12.5 years and most patients (83.5%) had one DFU. The majority of wounds (82.5%) were in the forefoot. Overall, 267/332 (80.5%) wounds healed. A greater proportion of wounds healed in the forefoot (82.5%) and midfoot (87.1%) than hindfoot (51.9%; p<0.001). Using a logistic regression model, palpable pedal pulse and use of a total contact cast were associated with better wound healing. Our findings are the first to demonstrate the benefits of chiropodists leading an acute care outpatient clinic in the management of DFUs in Canada and delivers wound healing outcomes equivalent to or exceeding those previously published.

The enhanced total body wrap--the new frontier in dressing care for burns.

Low, O-Wern; Chong, Si Jack; Tan, Bien-Keem

2013-11-01

The management of extensive burns with their associated high fluid exudate following burn excision and skin grafting has always posed a challenge in burn wound care. The ideal dressing should protect the wound from physical damage and micro-organisms; be comfortable and durable; allow high humidity at the wound; and be able to allow maximal activity for wound healing without retarding or inhibiting any stage of the process. The dressing technique described in this paper fulfils all the criteria above and at the same time provides an efficient channel to effectively clear the excessive exudate produced while keeping the wounds moist. Advantages conferred include accurate charting of wound exudate; reduced frequency of dressing changes; lower infection rates through prevention of strike-through; and securing and improving the viability of skin grafts. An enhancement to a technique previously described by us through the use of long thin strips of VAC sponges to transmit negative pressure, the enhanced Total Body Wrap aims to provide ideal conditions to promote healing in burns. Using negative pressure wound therapy (NPWT), this technique is simple and straightforward enough to be applied in majority of tertiary centres around the world. Copyright © 2013.

The paradox of negative pressure wound therapy--in vitro studies.

Negative-pressure wound therapy (NPWT) has revolutionised wound care. Yet, it is still not understood how hypobaric tissue pressure accelerates wound healing. There is very little reported on the relevant physics of any substance subjected to suction in this manner. The common assumption is that applying suction to a substance is likely to result in a reduction of pressure in that substance. Although more than 250 research articles have been published on NPWT, there are little data verifying whether suction increases or decreases the pressure of the substance it is applied to. Clarifying this basic question of physics is the first step in understanding the mechanism of action of these dressings. In this study, pressure changes were recorded in soft plasticene and processed meat, using an intracranial tissue pressure microsensor. Circumferential, non-circumferential and cavity NPWT dressings were applied, and pressure changes within the underlying substance were recorded at different suction pressures. Pressures were also measured at 1cm, 2 cm and 3 cm from the NPWT placed in a cavity. In all three types of NPWT dressings, the underlying substance pressure was increased (hyperbaric) as suction pressure increased. Although there was a substantial pressure increase at 1cm, the rise in pressure at the 2-cm and 3-cm intervals was minimal. Substance pressure beneath all types of NPWT dressing is hyperbaric in inanimate substances. Higher suction pressures generate greater substance pressures; however, the increased pressure rapidly dissipates as the distance from the dressing is increased. The findings of this study on inanimate objects suggest that we may need to review our current perception of the physics underlying NPWT dressings. Further research of this type on living tissues is warranted. Copyright (c) 2009 British Association of Plastic, Reconstructive and Aesthetic Surgeons. Published by Elsevier Ltd.

2014-10-01

The aim of this study was to describe district nurses' (DNs') experiences of their knowledge development in wound management when treating patients with different types of wounds at healthcare centers. In primary healthcare, DNs are mainly responsible for wound management. Previous research has focused on DNs' level of expertise regarding wound management, mostly based on quantitative studies. An unanswered question concerns DNs' knowledge development in wound management. The present study therefore intends to broaden understanding and to provide deeper knowledge in regard to the DNs' experiences of their knowledge development when treating patients with wounds. A qualitative descriptive design was used. Subjects were a purposeful sample of 16 DNs from eight healthcare centers in a metropolitan area in Stockholm, Sweden. The study was conducted with qualitative interviews and qualitative content analysis was used to analyze the data. The content analysis resulted in three categories and 11 sub-categories. The first category, 'ongoing learning by experience,' was based on experiences of learning alongside clinical practice. The second category 'searching for information,' consisted of various channels for obtaining information. The third category, 'lacking organizational support,' consisted of experiences related to the DNs' work organization, which hindered their development in wound care knowledge. The DNs experienced that they were in a constant state of learning and obtained their wound care knowledge to a great extent through practical work, from their colleagues as well as from various companies. A lack of organizational structures and support from staff management made it difficult for DNs to develop their knowledge and skills in wound management, which can lead to inadequate wound management.

Pressure ulcers are difficult to treat. Recent reports of low-temperature atmospheric-pressure plasma (LTAPP) indicated its safe and effectiveness in chronic wound care management. It has been shown both in vitro and vivo studies that LTAPP not only helps facilitate wound healing but also has antimicrobial efficacy due to its composition of ion and electron, free radicals, and ultraviolet ray. We studied the beneficial effect of LTAPP specifically on pressure ulcers. In a prospective randomized study, 50 patients with pressure ulcers were divided into 2 groups: Control group received standard wound care and the study group was treated with LTAPP once every week for 8 consecutive weeks in addition to standard wound care. We found that the group treated with LTAPP had significantly better PUSH (Pressure Ulcer Scale for Healing) scores and exudate amount after 1 week of treatment. There was also a reduction in bacterial load after 1 treatment regardless of the species of bacteria identified.

Dermatologic secondary procedures involve careful preoperative planning and patient preparation, skillful execution of the appropriate procedure, and thorough postoperative wound care. Many modalities of treatment are used, including skin preparation through elimination of inflammatory conditions, resurfacing of skin, and improvement of patient health. Proper selection of incisional design, local or regional flaps, and grafting techniques is key to successful revisional surgery. Care of the revised lesion or wound through medications, dressings and resurfacing techniques will optimize the end result.

The discovery of moist environment dressings as alternatives to the traditional treatments based on exposing wounds to air, opened new expectations for the care and treatment of chronic wounds. Over the years, these expectations have led to the availability of new moist environment dressings which have made it possible to improve the care provided to patients suffering this kind of wounds, as well as providing important reasons to weigh in terms of cost-benefit-effectiveness at the time of selecting which type of treatment should be employed. The lack of comparative analysis among traditional treatments and moist environment treatments for chronic wounds among patients receiving primary health care led the authors to perform an analysis comparing these aforementioned options of treatment on patients suffering venous leg ulcers or pressure ulcers. The authors designed a Randomized Clinical Trial involving patients receiving ambulatory care in order to compare the effectiveness and cost-benefit of traditional versus moist environment dressing during the treatment of patients suffering stage II or III pressure ulcers or venous leg ulcers. In this trial, variables related to effectiveness of both treatments, as well as their costs were analyzed. 70 wounds were included in this Randomized Clinical Trial, 41 were venous leg ulcers of which 21 received a moist environment treatment while 20 received traditional cure, the other 29 wounds were pressure ulcers of which 15 received moist environment dressings treatment and 14 received traditional dressings. No statistically significant differences were found among the defining variables for these lesions in either group under treatment. In the venous leg ulcer study group, the authors conclusions were an average of 18.13 days, 16.33 treatment sessions and a cost of 10,616 pesetas to heal one square centimeter of the initial surface area of a wound on patients treated with traditional treatment compared to an average of 18.22 days, 4.54 treatment sessions and a cost of 2409 pesetas to heal one square centimeter of the initial surface area of a wound on patients treated with moist environment dressings. In the pressure ulcers study group, the authors conclusions were an average of 12.18 days, 12.1 treatment sessions and a cost of 15,490 pesetas to heal one square centimeter of the initial surface area of a wound on patients treated with traditional treatment compared to an average of 7.12 days, 1.86 treatment sessions and a cost of 2610 pesetas to heal one square centimeter of the initial surface area of a wound on patients treated with moist environment dressings. The results of this randomized clinical trial demosntrated that the moist environment treatment group was more effective and had a better cost-benefit ratio than the traditional treatment group in the treatment of pressure ulcers and venous leg ulcers on patients cared for by nursing personnel in primary health care centers all of which agrees with publications consulted by authors.

Topical haemoglobin spray for diabetic foot ulceration.

PubMed

Bateman, Sharon Dawn

The development and subsequent deterioration of diabetic foot ulceration (DFU) is a common occurrence across all healthcare divides, concerning all patient groups, age, gender and social environments. It increases demand on clinical resources and creates unnecessary hardship for patients. Chronic DFU is challenging to prevent and notoriously difficult to manage owing to the complex nature of the patient and the disease itself. The improvement of oxygenation to many chronic wound groups is gaining momentum across wound care; particularly in those wounds such as DFU that present with circulatory, oxygen-deficient scenarios. A descriptive evaluation was undertaken in an acute clinical setting where a spray solution containing purified haemoglobin was used in a cohort of 20 patients who presented with chronic (>12 weeks) DFU. Standard wound care was undertaken by 18 health professionals with no changes to products, devices or practice before evaluation. All wounds received the addition of the product on eight set occasions over a 4-week period and the resulting data correlated in regards to the set outcomes of wound surface area reduction, ease of use, adverse events and patient acceptability. At 4 weeks all wounds had demonstrated positive wound reduction, there were no adverse events, all patients and clinicians found the product acceptable and easy to use. Interestingly, although not a set outcome, all wounds commenced the evaluation with wound-bed slough present and at 4 weeks 100% were deemed slough free. At a further 4-week review no patients wounds had regressed. The incorporation of a haemoglobin spray solution within this cohort of DFU resulted in a positive improvement in wound healing and slough elimination. Further work in this area is recommended to increase the evidence.

Honey as a dressing for chronic wounds in adults.

2002-10-01

The aim of this review was to identify whether in adults with chronic wounds the use of honey as a wound dressing improves wound management outcomes. As no randomized controlled trials or comparative studies comparing the use of honey as a chronic wound dressing with usual treatment could be found, the review is based on case studies and serial case studies. These were reviewed using a framework broadly based on wound care case study guidelines (Nelson, 2000) and cohort study guidelines (Greenhalgh and Donald, 2000). Based on the case studies reviewed, honey appears to be a useful dressing in adults with chronic wounds, but the available evidence is weak and therefore must be interpreted with caution.

The overall increase of chronic degenerative diseases associated with ageing makes wound care a tremendous socioeconomic burden. Thus, there is a growing need to develop novel wound healing therapies to improve cutaneous wound healing. The use of regenerative therapies is becoming increasingly popular due to the low-invasive procedures needed to apply them. Platelet-rich plasma (PRP) is gaining interest due to its potential to stimulate and accelerate the wound healing process. The cytokines and growth factors forming PRP play a crucial role in the healing process. This article reviews the emerging field of skin wound regenerative therapies with particular emphasis on PRP and the role of growth factors in the wound healing process. PMID:29346333

Mango butter was explored as a functional, natural supplement and active skin ingredient in skin care formulations. A foot care cream was developed with mango butter to evaluate its medicinal value and protective function in skin repair. Qualitative comparison and clinical case studies of the product were carried out. Wound healing potential of foot care cream was investigated on the rat excision and incision wound models. Results of the clinical studies demonstrated complete repair of worn and cracked skin in all the human volunteers. Furthermore, foot care cream exhibited significant healing response in both the wound models. The project work could be concluded as establishment of high potential for mango butter to yield excellent emolliency for better skin protection. Improving the product features and medicinal functionality further validate mango butter as a specialty excipient in development of cosmeceuticals and has an immense value for its commercialization.

Wound healing is an intricate process that requires complex coordination between many cell types and an appropriate extracellular microenvironment. Chronic wounds often suffer from high protease activity, persistent infection, excess inflammation, and hypoxia. While there has been intense investigation to find new methods to improve cutaneous wound care, the management of chronic wounds, burns, and skin wound infection remain challenging clinical problems. Ideally, advanced wound dressings can provide enhanced healing and bridge the gaps in the healing processes that prevent chronic wounds from healing. These technologies have great potential for improving outcomes in patients with poorly healing wounds but face significant barriers in addressing the heterogeneity and clinical complexity of chronic or severe wounds. Active wound dressings aim to enhance the natural healing process and work to counter many aspects that plague poorly healing wounds, including excessive inflammation, ischemia, scarring, and wound infection. This review paper discusses recent advances in the development of biomaterials and nanoparticle therapeutics to enhance wound healing. In particular, this review focuses on the novel cutaneous wound treatments that have undergone significant preclinical development or are currently used in clinical practice. PMID:27843895

Skin changes caused by aging increase the risk of skin damages, such as pressure ulcers, during hospitalization of elderly patients. There is few information about the cost of wound treatment in Brazil. Conversely, skin and wound problems are highly reported among hospitalized elderly patients and caregivers. The purpose is to analyze the socio-demographic and clinical profile associated with skin and wound care in hospitalized elderly. This is a prospective observational study. The sample consisted of 75 patients, aged 60 years or more, randomly selected in three hospitals in Rio de Janeiro, Brazil. Data extraction from nursing records of the sample, using cross mapping with Nursing Interventions Classification. Data Synthesis supported by SAS 6.11 (SAS Institute, Inc. Cary North Carolina) in association with SPSS version 14.0 and statistics analysis. The findings were: age standard deviation 7.8, with minimum as 60, and maximum as 91 years old. Prevalence of women and married seniors. High prevalence of long-term hospitalization. There were 21 Nursing Interventions in the nursing records and seventeen of them related to skin and wound care. They were described in 57 nursing activities, present during 376 evaluations and repeated 1756 times. A significant difference was obtained between age and the presence of the nursing interventions "Positioning" (p-0.004), Eye Care/Hygiene (p- < 0.0001) and Oral Health Maintenance (p-0.0003). The skin care to prevention and treatment of skin damages represented the major demand of nursing interventions in different clinical conditions of hospitalized elderly.

Electrical Stimulation for Pressure Injuries: A Health Technology Assessment

2017-01-01

Background Pressure injuries (bedsores) are common and reduce quality of life. They are also costly and difficult to treat. This health technology assessment evaluates the effectiveness, cost-effectiveness, budget impact, and lived experience of adding electrical stimulation to standard wound care for pressure injuries. Methods We conducted a systematic search for studies published to December 7, 2016, limited to randomized and non–randomized controlled trials examining the effectiveness of electrical stimulation plus standard wound care versus standard wound care alone for patients with pressure injuries. We assessed the quality of evidence through Grading of Recommendations Assessment, Development, and Evaluation (GRADE). In addition, we conducted an economic literature review and a budget impact analysis to assess the cost-effectiveness and affordability of electrical stimulation for treatment of pressure ulcers in Ontario. Given uncertainties in clinical evidence and resource use, we did not conduct a primary economic evaluation. Finally, we conducted qualitative interviews with patients and caregivers about their experiences with pressure injuries, currently available treatments, and (if applicable) electrical stimulation. Results Nine randomized controlled trials and two non–randomized controlled trials were found from the systematic search. There was no significant difference in complete pressure injury healing between adjunct electrical stimulation and standard wound care. There was a significant difference in wound surface area reduction favouring electrical stimulation compared with standard wound care. The only study on cost-effectiveness of electrical stimulation was partially applicable to the patient population of interest. Therefore, the cost-effectiveness of electrical stimulation cannot be determined. We estimate that the cost of publicly funding electrical stimulation for pressure injuries would be $0.77 to $3.85 million yearly for the next 5 years. Patients and caregivers reported that pressure injuries were burdensome and reduced their quality of life. Patients and caregivers also noted that electrical stimulation seemed to reduce the time it took the wounds to heal. Conclusions While electrical stimulation is safe to use (GRADE quality of evidence: high) there is uncertainty about whether it improves wound healing (GRADE quality of evidence: low). In Ontario, publicly funding electrical stimulation for pressure injuries could result in extra costs of $0.77 to $3.85 million yearly for the next 5 years. PMID:29201261

Current strategies for wound care provide limited relief to millions of patients who suffer from burns, chronic skin ulcers or surgical-related wounds. The goal of this work is to develop an in situ deposition of a personalized nanofibrous dressing via a handy electrospinning (e-spinning) device and evaluate its properties related to skin wound care. MCM-41 type mesoporous silica nanoparticles decorated with silver nanoparticles (Ag-MSNs) were prepared by a facile and environmentally friendly approach, which possessed long-term antibacterial activity and low cytotoxicity. Poly-ε-caprolactone (PCL) incorporated with Ag-MSNs was successfully electrospun (e-spun) into nanofibrous membranes. These in situ e-spun nanofibrous membranes allowed the continuous release of Ag ions and showed broad-spectrum antimicrobial activity against two common types of pathogens, Staphylococcus aureus and Escherichia coli. In addition, the in vivo studies revealed that these antibacterial nanofibrous membranes could reduce the inflammatory response and accelerate wound healing in Wistar rats. The above results strongly demonstrate that such patient-specific dressings could be broadly applied in emergency medical transport, hospitals, clinics and at the patients' home in the near future.Current strategies for wound care provide limited relief to millions of patients who suffer from burns, chronic skin ulcers or surgical-related wounds.

This article summarizes the WOCN Evidence-Based Clinical Practice Guideline for Management of Wounds in Patients with Lower Extremity Neuropathic Disease. It is intended for use by physicians, nurses, therapists, and other health care professionals who work with adults who have or are at risk for, lower-extremity neuropathic disease (LEND), and includes updated scientific literature available from January 2003 through February 2012. The full guideline contains definitions of lower extremity neuropathic disorders and disease, prevalence of the problem, relevance and significance of the disorders, as well as comprehensive information about etiology, the nervous system, pathogenesis, and the overall management goals for patients at risk for developing neuropathic foot ulcers. A detailed assessment section describes how to conduct a full clinical history and physical examination. The guideline also provides two approaches to interventions. The first focuses on prevention strategies to reduce the risk of developing LEND wounds or recurrence, including life-long foot offloading, routine dermal temperature surveillance, use of adjunctive therapies, medication management, and implementing lower extremity amputation prevention measures and patient self-care education. The second approach summarized LEND wound management strategies including wound cleansing, debridement, infection management, maintenance of intact peri-wound skin, nutrition considerations, pain and paresthesia management, edema management, offloading and management of gait and foot deformity, medication management, surgical options, adjunctive therapies, patient education, and health care provider follow-up. A comprehensive reference list, glossary of terms, and several appendices regarding an algorithm to determine wound etiology, pharmacology, Lower Extremity Amputation (LEAP) Program, diabetes foot screening and other information is available at the end of the guideline.

Impaired wound healing leading to skin ulceration is a serious complication of diabetes and may be caused by defective angiogenesis. Endothelial progenitor cells (EPCs) can augment neovascularisation in the ischaemic tissue. Experiments were performed to test the hypothesis that locally administered EPCs can promote wound healing in diabetes. Full-thickness skin wounds were created on the dorsum of diabetic mice. EPCs were obtained from bone marrow mononuclear cells (BMMNCs) and applied topically to the wound immediately after surgery. Vehicle and non-selective BMMNCs were used as controls. Wound size was measured on days 5, 10 and 14 after treatment, followed by resection, histological analysis and quantification of vascularity. Topical application of EPCs significantly promoted wound healing, as assessed by closure rate and wound vascularity. Immunostaining revealed that transplanted EPCs induced increased expression of vascular endothelial growth factor and basic fibroblast growth factor. Few EPCs were observed in the neovasculature based on in vivo staining of the functional vasculature. Ex vivo expanded EPCs promote wound healing in diabetic mice via mechanisms involving increased local cytokine expression and enhanced neovascularisation of the wound. This strategy exploiting the therapeutic capacity of autologously derived EPCs may be a novel approach to skin repair in diabetes. © 2012 The Authors.

Electrical Stimulation Technologies for Wound Healing

PubMed Central

Kloth, Luther C.

2014-01-01

Objective: To discuss the physiological bases for using exogenously applied electric field (EF) energy to enhance wound healing with conductive electrical stimulation (ES) devices. Approach: To describe the types of electrical currents that have been reported to enhance chronic wound-healing rate and closure. Results: Commercial ES devices that generate direct current (DC), and mono and biphasic pulsed current waveforms represent the principal ES technologies which are reported to enhance wound healing. Innovation: Wafer-thin, disposable ES technologies (wound dressings) that utilize mini or micro-batteries to deliver low-level DC for wound healing and antibacterial wound-treatment purposes are commercially available. Microfluidic wound-healing chips are currently being used with greater accuracy to investigate the EF effects on cellular electrotaxis. Conclusion: Numerous clinical trials described in subsequent sections of this issue have demonstrated that ES used adjunctively with standard wound care (SWC), enhances wound healing rate faster than SWC alone.

Successful wound care involves optimizing patient local and systemic conditions in conjunction with an ideal wound healing environment. Many different products have been developed to influence this wound environment to provide a pathogen-free, protected, and moist area for healing to occur. Newer products are currently being used to replace or augment various substrates in the wound healing cascade. This review of the current state of the art in wound-healing products looks at the latest applications of silver in microbial prophylaxis and treatment, including issues involving resistance and side effects, the latest uses of negative pressure wound devices, advanced dressings and skin substitutes, biologic wound products including growth factor applications, and hyperbaric oxygen as an adjunct in wound healing. With the abundance of available products, the goal is to find the most appropriate modality or combination of modalities to optimize healing. PMID:22567251

Negative pressure wound therapy (NPWT) is a widely accepted treatment modality for open or infected wounds. Premature ending of NPWT occasionally occurs due to negative effects on the quality of life (QoL), however, the actual impact on QoL is unknown. The aim of this review is to analyse the effect of NPWT versus standard wound care (SWC) on QoL when used for the treatment of open or infected wounds. A systematic literature search in a range of databases (PubMed, CINAHL, Medline, Web of Science, Science Direct Freedom Collection, SwetsWise, PSYCArticles and Infrotrac Custom Journals) using the following search terms; 'standard wound care', 'wound dressing', 'dressing', 'treatment', OR 'negative pressure wound therapy [MESH]', OR 'vacuum assisted closure' AND 'quality of life [MESH]', 'patient-satisfaction', OR 'experiences' was performed. Methodological quality was assessed using the methodological index for non-randomised studies (MINORS) checklist. There were 42 studies identified, five matched the inclusion criteria: two randomised clinical trials (RCTs), one clinical comparative study, one exploratory prospective cohort study and one quasi experimental pilot study. Median MINORS-score was 75% (58%-96%). There were seven different questionnaires used to measure QoL or a subsidiary outcome. QoL in the NPWT group was lower in the first week, though no difference in QoL was observed thereafter. This systematic review observed that QoL improved at the end of therapy independent of which therapy was used. NPWT led to a lower QoL during the first week of treatment, possible due to aniexty, after which a similar or better QoL was reported when compared with SWC. It could be suggested that NPWT might be associated with increased anxiety. All authors of this publication have received no financial support or have personal interests conflicting with the objectivity of this manuscript.

Marshall, Thomas J

2005-06-01

Operation Iraqi Freedom was the first large-scale combat operation involving the U.S. Marine Corps since the Persian Gulf War in 1991. Data from a combat surgical company are presented. Records of all U.S. and Iraqi combat casualties admitted to the surgical company were reviewed. Fifty-three (57%) of 93 patients suffered penetrating injuries. Most wounds were produced by high-explosive munitions (mines, hand grenades, and rocket-propelled grenades), and the majority (51%) of wounds were to the extremities. The time to surgical care averaged 4.7 hours (range, 1.5-48 hours), and 98% of the patients seen at our facility survived. The time from injury to surgical care was considered long by civilian standards; however, this did not appear to affect outcomes substantially. A small percentage (5.2%) of injuries were to the torso. Hypothermia was commonly present. Because of the nature of their wounds, all patients required additional surgery after evacuation to rear area facilities. The outcomes of individual patients are not known, although it is known that only one Marine died after reaching medical care and, to date, no Marines have subsequently died of their wounds.

Biliary wound healing, ductular reactions, and IL-6/gp130 signaling in the development of liver disease

PubMed Central

Demetris, A J; III, John G Lunz; Specht, Susan; Nozaki, Isao

2006-01-01

Basic and translational wound healing research in the biliary tree lag significantly behind similar studies on the skin and gastrointestinal tract. This is at least partly attributable to lack of easy access to the biliary tract for study. But clinical relevance, more interest in biliary epithelial cell (BEC) pathophysiology, and widespread availability of BEC cultures are factors reversing this trend. In the extra-hepatic biliary tree, ineffectual wound healing, scarring and stricture development are pressing issues. In the smallest intra-hepatic bile ducts either impaired BEC proliferation or an exuberant response can contribute to liver disease. Chronic inflammation and persistent wound healing reactions in large and small bile ducts often lead to liver cancer. General concepts of wound healing as they apply to the biliary tract, importance of cellular processes dependent on IL-6/gp130/STAT3 signaling pathways, unanswered questions, and future directions are discussed.

Atypical gunshot injury to the right side of the face with the bullet lodged in the carotid sheath: a case report.

Gunshot injuries of the head and neck from the AK-47 rifle (a common assault rifle, submachine gun type) are a significant contributor to morbidity and mortality among civilians in Sub-Saharan Africa. They may cause significant damage to the closely arranged structures in this region, and the bullet's trajectory can be very difficult to determine. We present an unusual case of gunshot injury with an atypical bullet entry wound, profound injury to the face, lodgment in the right carotid sheath, and 'wandering'; a first of its kind in East Africa. A 27-year-old African-Ugandan woman of Nilotic ethnicity was referred to the Accident and Emergency Department of a tertiary hospital in Uganda, having sustained complex injuries due to an inadvertent AK-47 rifle gunshot injury. The gunshot injury was to the right side of her face with a large ragged entry wound and no exit wound. Prior basic wound care and radiological imaging showed a comminuted fracture of her mandible with lodgment of the bullet in her neck, anterior to her sixth and seventh cervical vertebrae. Standard debridement of her wound was done. A computed tomography scan showed an apparent cephalad shift ('wandering') of the bullet, leaving it lying partially anterior to her fifth cervical vertebra as well as within her carotid sheath. Other injuries were to her facial and trigeminal nerves, and her middle ear. The 'wandering' bullet was successfully removed surgically. It had caused no damage to any part of her neck structure. AK-47 rifle bullet injuries may present with uncharacteristically large entry wounds and cause complex structural injuries at the area of impact. The consequent trajectory is difficult to predict making regional examination and radiological investigations essential in management. Bullets may be retained, leaving no exit wound. Securing the airway, controlling hemorrhage and identifying other injuries are the first vital steps. This case illustrates all these interventions and the important decision to extract the entrapped bullet from the patient's neck because it had started to 'wander' and could have caused grave injury over time with further migration. Maxillofacial, plastic, trauma, general and military surgeons, otorhinolaryngologists and emergency physicians can gain from this experience because it calls for a multidisciplinary team approach.

Laser skin resurfacing (LSR) has been used for facial rejuvenation for the last 20 years. Posttreatment care after LSR is essential to decrease the risk of complications. Currently, no unified standards or criteria exist for invasive LSR posttreatment care. We aimed to identify the optimal wound care timing and choice of specific local, systemic, and general medical measures required to decrease complications. We performed a systematic search of the PubMed/MEDLINE electronic databases and included only articles written and published in the English language, with no restrictions on the publication time (year). The search yielded 316 potentially relevant articles, 133 of which met our review criteria. Most of the studies on this topic have focused on wound care during the early stage, typically the first 2 weeks. Closed dressings may offer a more ideal, moist wound environment. The use of medications must be judicious. The ongoing emergence of new methods and products warrants evaluation in future large clinical trials. Familiarity with the complications following invasive LSR and the provision of optimal, effective, and timely posttreatment care may substantially decrease the risks associated with the treatment modality.

We have conducted a basic study on the influences on ultrasonic properties when LIPUS is applied through wound dressing. According to the results of ex vivo experiments conducted to date, LIPUS showed ultrasonic properties such as transmittance, coefficient of transmission, and a non-uniformity ratio through film wound dressing better than other wound dressing, and it was considered that LIPUS's effect for fracture healing was not influenced by film wound dressing. Then, we discussed the influence on the effect of LIPUS through film wound dressing. Thirty male 8-week-old Sprague-Dawley rats were used for the trial. After creating close transverse femoral fractures on the right legs of these 30 rats, they were divided into 3 groups of 10; LIPUS through wound dressing (Group A), LIPUS without wound dressing (Group B), and No LIPUS treatment (Group C). OPSITE Wound, which was thought to have the least influence on ultrasound properties, was used for this trial. Group A and B received LIPUS for 20 minutes a day from the first day after the fractures. LIPUS was generated from Teijin Pharma's device for a basic experiment. When treating Group A, the wound dressing was pasted on the ultrasound terminal in order to apply LIPUS through the dressing. We assessed the time-oriented morphological change of each group in anesthetized condition using simple radiographs on the 8th, 16th, and 24th day after the fractures. Six rats in Group A, 2 in Group B, and 1 in Group C died in anesthesia, and we discussed the remaining 4 rats in Group A, 8 in Group B, and 9 in Group C. We defined more than one teleost callus bridging as bone-union. We also counted a bone remodeling when we recognized the absorption of existing cortical bone and the transformation of new bone to cortical bone in simple radiographs. As a result, compared with Group C, we recognized that both bone union and remodeling accelerated remarkably in Group B, but not in Group A. It suggested that LIPUS through wound dressing had negative influences on both period shorting of fracture healing and bone remodeling. When LIPUS was conducted through film wound dressing, transmittance and coefficient of transmission were unchanged; however, the non-uniformity ratio changed slightly. The non-uniformity ratio of the ultrasound transducer had a significant influence on the effect of LIPUS on fracture healing.

Burn Wound Infections

Burns are one of the most common and devastating forms of trauma. Patients with serious thermal injury require immediate specialized care in order to minimize morbidity and mortality. Significant thermal injuries induce a state of immunosuppression that predisposes burn patients to infectious complications. A current summary of the classifications of burn wound infections, including their diagnosis, treatment, and prevention, is given. Early excision of the eschar has substantially decreased the incidence of invasive burn wound infection and secondary sepsis, but most deaths in severely burn-injured patients are still due to burn wound sepsis or complications due to inhalation injury. Burn patients are also at risk for developing sepsis secondary to pneumonia, catheter-related infections, and suppurative thrombophlebitis. The introduction of silver-impregnated devices (e.g., central lines and Foley urinary catheters) may reduce the incidence of nosocomial infections due to prolonged placement of these devices. Improved outcomes for severely burned patients have been attributed to medical advances in fluid resuscitation, nutritional support, pulmonary and burn wound care, and infection control practices.

Evaluation of a honey-impregnated tulle dressing in primary care.

PubMed

Stephen-Haynes, Jackie

2004-06-01

Honey has been used for its healing properties for centuries and has been used to dress wounds with favourable results. The emergence of antibiotic resistance and growing interest in "natural" or "complementary" therapies has led to an interest in honey dressings. Much of the research to date has been related to honey's antibacterial properties. However, the healing properties claimed for honey also include stimulating new tissue growth, moist wound healing, fluid handling and promoting epithelialization. Until recently, honey had not been developed as a wound management product and was not a certified pharmaceutical device. Activon Tulle is a sterile, non-adherent dressing impregnated with Leptospermum scoparium hone. The claimed properties of honey dressings would make this a valuable addition to the dressing currently available in the primary care setting. An evaluation was undertaken involving 20 patients with a variety of wounds. A conclusion is drawn that while further research is needed, medical grade honey does appear to be a valuable addition to the wound management formulary.

Local Wound Care for Primary Cleft Lip Repair: Treatment and Outcomes With use of Topical Hydrogen Peroxide.

This study highlights and validates a peroxide-based wound healing strategy for treatment of surgically closed facial wounds in a pediatric population. The authors identified pediatric patients undergoing primary cleft lip repair as a specific population to evaluate the outcomes of such a protocol. Through analysis of defined outcome measures, a reliable and reproducible protocol for postoperative wound care following primary cleft lip repair with favorable results is described. This retrospective study analyzes wound healing outcomes in pediatric patients undergoing primary cleft lip repair from 2006 to 2011 at a tertiary academic center. The wound healing protocol was used in both primary unilateral and bilateral repairs. One hundred fortysix patients between the ages of 0 and 4 years underwent primary cleft lip repair and cleft rhinoplasty by a single, fellowship-trained craniofacial surgeon. Postoperatively, wounds were treated with half-strength hydrogen peroxide and bacitracin, as well as scar massage. Incisional dehiscence, hypertrophic scar formation, discoloration, infection, and reoperation were studied. Outcomes were evaluated in light of parent compliance, demographics, preoperative nasoalveolar molding (PNAM), and diagnosis. The authors identified 146 patients for inclusion in this study. There was no wound or incisional dehiscence. One hundred twenty-four patients demonstrated favorable cosmetic outcome. Only 3 (2%) of patients who developed suboptimal outcomes underwent secondary surgical revision (> 1 year after surgery). Demographic differences were not statistically significant, and PNAM treatment did not influence outcomes. These data validate the use of halfstrength hydrogen peroxide and bacitracin as part of a wound healing strategy in pediatric incisional wounds. The use of hydrogen peroxide produced comparable outcomes to previously published studies utilizing other wound healing strategies and, therefore, these study findings support the further use of this regimen for this particular population.

To estimate the patterns of care and related resource use attributable to managing acute and chronic wounds among a catchment population of a typical clinical commissioning group (CCG)/health board and corresponding National Health Service (NHS) costs in the UK. This was a sub-analysis of a retrospective cohort analysis of the records of 2000 patients in The Health Improvement Network (THIN) database. Patients' characteristics, wound-related health outcomes and health-care resource use were quantified for an average CCG/health board with a catchment population of 250,000 adults ≥18 years of age, and the corresponding NHS cost of patient management was estimated at 2013/2014 prices. An average CCG/health board was estimated to be managing 11,200 wounds in 2012/2013. Of these, 40% were considered to be acute wounds, 48% chronic and 12% lacking any specific diagnosis. The prevalence of acute, chronic and unspecified wounds was estimated to be growing at the rate of 9%, 12% and 13% per annum respectively. Our analysis indicated that the current rate of wound healing must increase by an average of at least 1% per annum across all wound types in order to slow down the increasing prevalence. Otherwise, an average CCG/health board is predicted to manage ~23,200 wounds per annum by 2019/2020 and is predicted to spend a discounted (the process of determining the present value of a payment that is to be received in the future) £50 million on managing these wounds and associated comorbidities. Real-world evidence highlights the substantial burden that acute and chronic wounds impose on an average CCG/health board. Strategies are required to improve the accuracy of diagnosis and healing rates.

Utilizing the VeraFlo™ Instillation Negative Pressure Wound Therapy System with Advanced Care for a Case Study

PubMed Central

2016-01-01

Background: Mankind has always suffered wounds throughout time due to trauma, disease, and lifestyles. Many wounds are non-healing and have continued to be challenging. However, utilizing advanced wound care treatments, such as negative pressure wound treatment with instillation and dwell time (NPWTi-d), has proven beneficial. NPWTi-d is indicated in a variety of wounds, such as trauma, surgical, acute, pressure injuries, diabetic foot ulcers, and venous leg ulcers. Bacteria and bioburden interrupts wound healing by increasing the metabolic needs, ingesting, and robbing the necessary nutrients and oxygen. Instillation therapy is the technique of intermittently washing out a wound with a liquid solution. The mechanism of action is instilling fluid into the wound bed, soaking for a determined time, loosening and cleaning of exudate, contaminants, and/or infection, removing fluid via negative pressure, thus promoting tissue growth. Case study: The patient was diagnosed with a large lymphedema mass on the right upper thigh. Surgical removal of the lymphedema mass was indicated due to interference with quality of life. After a failed flap and surgical debridement, NPWTi-d with normal saline was implemented. Results: The patient had excellent results, with obvious forming of red, beefy granulation, epithelization tissue development, and a cleaner, healthier wound bed. Settings for the NPWTi-d was 18 minutes dwell time, every 2.5 hours with a constant pressure of 125 mm/hg pressure. Conclusion: The NPWTi-d demonstrated to be an instrumental treatment in supporting and stimulating healing. Early application of the treatment with normal saline as the instillation fluid prepared the previously failed wound for quicker healing. PMID:28070472

Low-level laser therapy (LLLT) using superpulsed near-infrared light can penetrate deeper in the injured tissue and could allow non-pharmacological treatment for chronic wound healing. This study investigated the effects of superpulsed laser (Ga-As 904 nm, 200 ns pulse width; 100 Hz; 0.7 mW mean output power; 0.4 mW/cm(2) average irradiance; 0.2 J/cm(2) total fluence) on the healing of burn wounds in rats, and further explored the probable associated mechanisms of action. Irradiated group exhibited enhanced DNA, total protein, hydroxyproline and hexosamine contents compared to the control and silver sulfadiazine (reference care) treated groups. LLLT exhibited decreased TNF-α level and NF-kB, and up-regulated protein levels of VEGF, FGFR-1, HSP-60, HSP-90, HIF-1α and matrix metalloproteinases-2 and 9 compared to the controls. In conclusion, LLLT using superpulsed 904 nm laser reduced the inflammatory response and was able to enhance cellular proliferation, collagen deposition and wound contraction in the repair process of burn wounds. Photomicrographs showing no, absence inflammation and faster wound contraction in LLLT superpulsed (904 nm) laser treated burn wounds as compared to the non-irradiated control and silver sulfadiazine (SSD) ointment (reference care) treated wounds. © 2014 WILEY-VCH Verlag GmbH & Co.

To present a 10-step approach to the assessment and treatment of pilonidal sinus disease (PSD) and related wounds based on the Harris protocol, expert opinion, and a current literature review. This continuing education activity is intended for physicians and nurses with an interest in skin and wound care. After participating in this educational activity, the participant should be better able to: Pilonidal sinus disease (PSD) is a common problem in young adults and particularly in males with a deep natal or intergluteal cleft and coarse body hair. An approach to an individual with PSD includes the assessment of pain, activities of daily living, the pilonidal sinus, and natal cleft. Local wound care includes the management of infection (if present), along with appropriate debridement and moisture management. Treatment is optimized with patient empowerment to manage the wound and periwound environment (cleansing, dressing changes, decontamination, hair removal, minimizing friction). Self-care education includes the recognition of recurrences or infection. Early surgical intervention of these wounds is often necessary for successful outcomes. Pilonidal sinus healing by secondary intention often takes weeks to months; however, the use of the Harris protocol may decrease healing times. A number of new surgical approaches may accelerate healing. Surgical closure by primary intention is often associated with higher recurrence rates. Expert opinion in this article is combined with an evidence-based literature review. The authors have tabulated 10 key steps from the Harris protocol, including a review of the surgical techniques to improve PSD patient outcomes.

Complex wounds (superficial-, partial-, or full-thickness skin loss wounds healing by secondary intention) are common; however, there is a lack of high-quality, contemporary epidemiological data. This paper presents point prevalence estimates for complex wounds overall as well as for individual types. A multiservice, cross-sectional survey was undertaken across a United Kingdom city (Leeds, population 751,485) during 2 weeks in spring of 2011. The mean age of people with complex wounds was approximately 70 years, standard deviation 19.41. The point prevalence of complex wounds was 1.47 per 1,000 of the population, 95% confidence interval 1.38 to 1.56. While pressure ulcers and leg ulcers were the most frequent, one in five people in the sample population had a less common wound type. Surveys confined to people with specific types of wound would underestimate the overall impact of complex wounds on the population and health care resources. © 2014 The Authors.

MedWatch, the Food and Drug Administration's (FDA's) nationwide adverse event reporting system, serves to monitor device performance after a medical device is approved or cleared for market. Through the MedWatch adverse event reporting system, the FDA receives Medical Device Reports of deaths and serious injuries with negative-pressure wound therapy (NPWT) systems, many of which are used in homes and in extended-care facilities. In response to reported events, this study was conducted to obtain additional information about device issues that healthcare professionals face in these settings, as well as challenges that caregivers might encounter using this technology at home. The study was exploratory and descriptive in nature. The FDA surveyed wound care specialists and professional home healthcare providers to learn about users' experiences with NPWT. In the first phase of the study, a semistructured questionnaire was developed for telephone interviews and self-administration. In the second phase, a web-based survey was adapted from the semistructured instrument. Respondent concerns primarily centered on issues not directly related to the NPWT devices: NPWT prescription, provider education in addition to patient training and appropriate wound management practices, notably ongoing wound assessment, and patient monitoring. Overall, respondents thought that there was a definite benefit to NPWT, regardless of the care setting, and that it was a safe therapy when prescribed and administered appropriately.

Review: African medicinal plants with wound healing properties.

Wounds of various types including injuries, cuts, pressure, burns, diabetic, gastric and duodenal ulcers continue to have severe socio-economic impact on the cost of health care to patients, family and health care institutions in both developing and developed countries. However, most people in the developing countries, especially Africa, depend on herbal remedies for effective treatment of wounds. Various in vitro and in vivo parameters are used for the evaluation of the functional activity of medicinal plants by using extracts, fractions and isolated compounds. The aim of the review is to identify African medicinal plants with wound healing properties within the last two decades. Electronic databases such as PubMed, Scifinder(®) and Google Scholar were used to search and filter for African medicinal plants with wound healing activity. The methods employed in the evaluation of wound healing activity of these African medicinal plants comprise both in vivo and in vitro models. In vivo wound models such as excision, incision, dead space and burn wound model are commonly employed in assessing the rate of wound closure (contraction), tensile strength or breaking strength determination, antioxidant and antimicrobial activities, hydroxyproline content assay and histological investigations including epithelialisation, collagen synthesis, and granulation tissue formation. In in vitro studies, single cell systems are mostly used to study proliferation and differentiation of dermal fibroblasts and keratinocytes by monitoring typical differentiation markers like collagen and keratin. In this study, 61 plants belonging to 36 families with scientifically demonstrated or reported wound healing properties were reviewed. Various plant parts including leaves, fruits, stem bark and root extracts of the plants are used in the evaluation of plants for wound healing activities. Although, a variety of medicinal plants for wound healing can be found in literature, there is a need for the isolation and characterization of the bioactive compounds responsible for the wound healing properties. Also, cytotoxicity studies should be performed on the promising agents or bioactive fractions or extracts. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Design and implementation of a dual-wavelength intrinsic fluorescence camera system

NASA Astrophysics Data System (ADS)

Ortega-Martinez, Antonio; Musacchia, Joseph J.; Gutierrez-Herrera, Enoch; Wang, Ying; Franco, Walfre

2017-03-01

Intrinsic UV fluorescence imaging is a technique that permits the observation of spatial differences in emitted fluorescence. It relies on the fluorescence produced by the innate fluorophores in the sample, and thus can be used for marker-less in-vivo assessment of tissue. It has been studied as a tool for the study of the skin, specifically for the classification of lesions, the delimitation of lesion borders and the study of wound healing, among others. In its most basic setup, a sample is excited with a narrow-band UV light source and the resulting fluorescence is imaged with a UV sensitive camera filtered to the emission wavelength of interest. By carefully selecting the excitation/emission pair, we can observe changes in fluorescence associated with physiological processes. One of the main drawbacks of this simple setup is the inability to observe more than a single excitation/emission pair at the same time, as some phenomena are better studied when two or more different pairs are studied simultaneously. In this work, we describe the design and the hardware and software implementation of a dual wavelength portable UV fluorescence imaging system. Its main components are an UV camera, a dual wavelength UV LED illuminator (295 and 345 nm) and two different emission filters (345 and 390 nm) that can be swapped by a mechanical filter wheel. The system is operated using a laptop computer and custom software that performs basic pre-processing to improve the image. The system was designed to allow us to image fluorescent peaks of tryptophan and collagen cross links in order to study wound healing progression.

Background: Despite advances in traumatic wound care and management, infections remain a leading cause of mortality, morbidity and economic disruption in millions of wound patients around the world. Animal models have become standard tools for studying a wide array of external traumatic wound infections and testing new antimicrobial strategies. Results: Animal models of external traumatic wound infections reported by different investigators vary in animal species used, microorganism strains, the number of microorganisms applied, the size of the wounds and for burn infections, the length of time the heated object or liquid is in contact with the skin. Methods: This review covers experimental infections in animal models of surgical wounds, skin abrasions, burns, lacerations, excisional wounds and open fractures. Conclusions: As antibiotic resistance continues to increase, more new antimicrobial approaches are urgently needed. These should be tested using standard protocols for infections in external traumatic wounds in animal models. PMID:21701256

Anaesthetic and critical care management of thoracic injuries.

PubMed

Round, J A; Mellor, A J

2010-09-01

Thoracic wounding has been a relatively common presentation of military wounds throughout modern conflict. When civilian casualties are included the incidence has remained constant at around 10%, although the frequency and severity of wounds to combatants has been altered by modern body armour. Whilst thoracic injury has a high initial mortality on the battlefield, those surviving to reach hospital frequently have injuries that only require simple management. In addition to penetrating ballistic injury, blunt chest trauma frequently occurs on operations as a result of road traffic collisions or tertiary blast injury. The physiological impact of thoracic wounds, however, is often great and survivors often require intensive care management and, where available, complex strategies to ensure oxygenation and carbon dioxide removal. This review examines the incidence and patterns of thoracic trauma and looks at therapeutic options for managing these complex cases.

Wound care guidelines and formulary for community nurses.

PubMed

Baeyens, T A

2000-03-01

Community nursing is experiencing significant change as a result of developments such as improved technology, care in the community and earlier discharge of patients from hospital. Because of this, increasingly complex clinical care is required in the community, and it has been noted that community nurses are 'under considerable pressure' and show 'evidence of high stress and low morale'. Wound care is one area in which community nurses constantly battle to keep abreast of continual change. Growing product availability and diversity of use, changes in dressing techniques and the ever-increasing costs associated with wound care mean decision-making in wound care is often a complex task. In the Grampian region, a handbook of evidence-based practice guidelines with a product formulary was developed and distributed to all community nurses. The handbook was designed to ease the decision-making process by evaluating evidence-based practice and local preferences to recommend and guide nurses towards effective clinical practice and cost efficiency. All grades of district nurse in the region have been issued with their own copy of the handbook. It is presented in an A5 ring-binder format to make it easy to carry and to facilitate updating using loose-leaf inserts. The use of logos, extra information boxes and colour coding makes it easy for users to find specific areas of interest in the handbook. The success of the handbook has led to debate on the potential for development of a similar resource for use by practice nurses and in local community hospitals.

Pain is a common and significant feature of burn injury. The use of intravenous opioids forms the mainstay of procedural burn pain management, but in an outpatient setting, the demand for novel agents that do not require parenteral access, are easy to administer and have a rapid onset are urgently needed. One such agent is the inhaled anaesthetic agent, methoxyflurane (MF). The aim of this study was to conduct a pilot investigation into the clinical effectiveness of MF inhaler on pain and anxiety scores in patients undergoing burn wound care procedures in an outpatient setting. A prospective case series involved recruiting patients undergoing a burn wound care procedure in an ambulatory burn care setting. Pain and anxiety were assessed using numerical rating scales. Overall, median numerical pain rating score was significantly higher post-dressing [pre-dressing: 2; interquartile range (IQR): 1-3 versus post-dressing: 3; IQR 1·5-4; P = 0·01], whereas median numerical anxiety score significantly reduced following the dressing (pre-dressing: 5; IQR 4-7 versus post-dressing: 2; IQR 1-2; P < 0·001). Our study suggests that there is a role for MF in the pain management armamentarium in those undergoing burn care procedures in the ambulatory care setting. However, there is an urgent need for larger case series and randomised controlled trials to determine its overall clinical effectiveness. © 2012 The Authors.

It's not what you put on, but what you take off: techniques for debriding and off-loading the diabetic foot wound.

PubMed

Armstrong, David G; Lavery, Lawrence A; Nixon, Brent P; Boulton, Andrew J M

2004-08-01

The basic etiology of neuropathic diabetic foot wounds involves pressure in conjunction with cycles of repetitive stress, leading to failure of skin and soft tissue. The central tenet of any treatment plan addressing neuropathic diabetic foot wounds is the appropriate debridement of nonviable tissue coupled with adequate pressure relief (off-loading). Although numerous advances have been made in the treatment of diabetic foot wounds, including bioengineered tissues, autologous and exogenous cytokine delivery systems, and potentially effective topical antimicrobial modalities, none will succeed without addressing effective debridement and off-loading. Specific debridement and off-loading techniques are discussed, along with available supporting evidence. This includes the use of the "instant" total contact cast, among other modalities.

In this review, we describe current and future potential wound healing treatments for acute and chronic wounds. The current wound healing approaches are based on autografts, allografts, and cultured epithelial autografts, and wound dressings based on biocompatible and biodegradable polymers. The Food and Drug Administration approved wound healing dressings based on several polymers including collagen, silicon, chitosan, and hyaluronic acid. The new potential therapeutic intervention for wound healing includes sustained delivery of growth factors, and siRNA delivery, targeting microRNA, and stem cell therapy. In addition, environment sensors can also potentially utilize to monitor and manage microenvironment at wound site. Sensors use optical, odor, pH, and hydration sensors to detect such characteristics as uric acid level, pH, protease level, and infection - all in the hopes of early detection of complications.

We recently performed proteomic characterization of a modified collagen gel (MCG) dressing and reported promising effects of the gel in healing full-thickness excisional wounds. In this work, we test the translational relevance of our aforesaid findings by testing the dressing in a swine model of chronic ischemic wounds recently reported by our laboratory. Full-thickness excisional wounds were established in the center of bipedicle ischemic skin flaps on the backs of animals. Ischemia was verified by laser Doppler imaging, and MCG was applied to the test group of wounds. Seven days post wounding, macrophage recruitment to the wound was significantly higher in MCG-treated ischemic wounds. In vitro, MCG up-regulated expression of Mrc-1 (a reparative M2 macrophage marker) and induced the expression of anti-inflammatory cytokine interleukin (IL)-10 and of fibroblast growth factor-basic (β-FGF). An increased expression of CCR2, an M2 macrophage marker, was noted in the macrophages from MCG treated wounds. Furthermore, analyses of wound tissues 7 days post wounding showed up-regulation of transforming growth factor-β, vascular endothelial growth factor, von Willebrand's factor, and collagen type I expression in MCG-treated ischemic wounds. At 21 days post wounding, MCG-treated ischemic wounds displayed higher abundance of proliferating endothelial cells that formed mature vascular structures and increased blood flow to the wound. Fibroblast count was markedly higher in MCG-treated ischemic wound-edge tissue. In addition, MCG-treated wound-edge tissues displayed higher abundance of mature collagen with increased collagen type I : III deposition. Taken together, MCG helped mount a more robust inflammatory response that resolved in a timely manner, followed by an enhanced proliferative phase, angiogenic outcome, and postwound tissue remodeling. Findings of the current study warrant clinical testing of MCG in a setting of ischemic chronic wounds. © 2014 by the Wound Healing Society.

Hyperbaric Oxygen Therapy and Oxygen Compatibility of Skin and Wound Care Products

Bernatchez, Stéphanie F.; Tucker, Joseph; Chiffoleau, Gwenael

2017-01-01

Objective: Use test methods to assess the oxygen compatibility of various wound care products. Approach: There are currently no standard test methods specifically for evaluating the oxygen compatibility and safety of materials under hyperbaric oxygen (HBO) conditions. However, tests such as the oxygen index (OI), oxygen exposure (OE), and autogenous ignition temperature (AIT) can provide useful information. Results: The OI test measures the minimum oxygen concentration that will support candle-like burning, and it was used to test 44 materials. All but two exhibited an OI equal to or greater (safer) than a control material commonly used in HBO. The OE test exposes each material to an oxygen-enriched atmosphere (>99.5% oxygen) to monitor temperature and pressure for an extended duration. The results of the OE testing indicated that none of the 44 articles tested with this method self-ignited within the 60°C, 3 atm pressurized oxygen atmosphere. The AIT test exposes materials to a rapid ramp up in temperature in HBO conditions at 3 atm until ignition occurs. Ten wound care materials and seven materials usually avoided in HBO chambers were tested. The AIT ranged from 138°C to 384°C for wound care products and from 146°C to 420°C for the other materials. Innovation: This work provides useful data and recommendations to help develop a new standard approach for evaluating the HBO compatibility of wound care products to ensure safety for patients and clinicians. Conclusion: The development of an additional test to measure the risk of electrostatic discharge of materials in HBO conditions is needed. PMID:29098113

Integrating palliative care with usual care of diabetic foot wounds.

PubMed

Dunning, Trisha

2016-01-01

Palliative care is a philosophy and a system for deciding care and can be used alone or integrated with usual chronic disease care. Palliative care encompasses end-of-life care. Palliative care aims to enhance quality of life, optimize function and manage symptoms including early in the course of chronic diseases. The purposes of this article are to outline palliative care and discuss how it can be integrated with usual care of diabetic foot wounds. Many people with diabetes who have foot wounds also have other comorbidities and diabetes complications such as cardiovascular and renal disease and depression, which affect medicine and other treatment choices, functional status, surgical risk and quality of life. Two broad of diabetic foot disease exist: those likely to heal but who could still benefit from integrated palliative care such as managing pain and those where healing is unlikely where palliation can be the primary focus. People with diabetes can die suddenly, although the life course is usually long with periods of stable and unstable disease. Many health professionals are reluctant to discuss palliative care or suggest people to document their end-of-life care preferences. If such preferences are not documented, the person might not achieve their desired death or place of death and health professionals and families can be confronted with difficult decisions. Palliative care can be integrated with usual foot care and is associated with improved function, better quality of life and greater patient and family satisfaction.

Negative pressure wound therapy (NPWT) is widely used in the management of acute and chronic wounds. The purpose of this 8-week study was to evaluate outcomes of using a new canisterless, portable, single-use NPWT system in patients with wounds treated in a Canadian community healthcare setting. The device is designed to provide negative pressure at 80±20 mm Hg, 24 hours a day of continuous usage, for a maximum wear time of 7 days. Data on wound outcomes, including exudate levels, wound appearance, and wound area, were collected weekly by a Registered Nurse as part of routine practice. When treatment was discontinued, patients and nurses were asked to rate their satisfaction with the device. Data from patients who had used a conventional NPWT device to manage their wounds were retrospectively abstracted from their medical records. In the prospective study, conducted between October 2011 and July 2012, 326 patients (median age=61 years; range 17-91 years) with wounds of mixed etiology (53 pressure ulcers, 21 venous leg ulcers, 16 diabetic foot ulcers, and 15 traumatic and 221 surgical wounds) were treated for a maximum of 8 weeks with the portable NPWT device. The majority of patients (228 out of 326; 68%) achieved complete wound closure within 8 weeks of treatment. The Kaplan-Meier estimate of median time to healing of all wounds was 9 weeks. The majority of patients (318 patients, 97%) reported they were pleased or satisfied with the dressing performance. Nurses indicated satisfaction with the dressing performance for all but two patients (99%). The majority (89%) of patients managed with conventional NPWT (n=539) had an open surgical wound with moderate or high levels of exudate. Healing rates in the portable and conventional NPWT group were similar (10% to 11% per week). Portable, single-use NPWT has the potential to deliver good wound outcomes in community care settings and simplify the use of negative pressure for nurses and patients. Additional research is needed to evaluate treatment efficacy and cost effectiveness.

Molecular cloning and characterization of a tomato cDNA encoding a systemically wound-inducible bZIP DNA-binding protein

NASA Technical Reports Server (NTRS)

Stankovic, B.; Vian, A.; Henry-Vian, C.; Davies, E.

2000-01-01

Localized wounding of one leaf in intact tomato (Lycopersicon esculentum Mill.) plants triggers rapid systemic transcriptional responses that might be involved in defense. To better understand the mechanism(s) of intercellular signal transmission in wounded tomatoes, and to identify the array of genes systemically up-regulated by wounding, a subtractive cDNA library for wounded tomato leaves was constructed. A novel cDNA clone (designated LebZIP1) encoding a DNA-binding protein was isolated and identified. This clone appears to be encoded by a single gene, and belongs to the family of basic leucine zipper domain (bZIP) transcription factors shown to be up-regulated by cold and dark treatments. Analysis of the mRNA levels suggests that the transcript for LebZIP1 is both organ-specific and up-regulated by wounding. In wounded wild-type tomatoes, the LebZIP1 mRNA levels in distant tissue were maximally up-regulated within only 5 min following localized wounding. Exogenous abscisic acid (ABA) prevented the rapid wound-induced increase in LebZIP1 mRNA levels, while the basal levels of LebZIP1 transcripts were higher in the ABA mutants notabilis (not), sitiens (sit), and flacca (flc), and wound-induced increases were greater in the ABA-deficient mutants. Together, these results suggest that ABA acts to curtail the wound-induced synthesis of LebZIP1 mRNA.

Stop the hunting: using a wound care-specific EMR for 'just-in-time" supply ordering.

PubMed

Turner, Toni; Walker, David

2007-01-01

Ensuring adequate stocks of wound care supplies at wound care to be tied up, and too little can cause problems for patients. Most facilities maintain a "par" level for each item, which requires that supplies be ordered even if the "par" is numerically short by one item. In addition, due to the current just-in-time environment, if attention is not paid to the par level, unexpected shortages of supplies can develop. By using Inventory Trak software developed by Intellicure, facility managers will always know how much stock is presentfor each item, as individual item barcodes are registered in the system each time an item is used through software-linking scanners. The result is increased efficiency, reduced cost to the facility, and an assurance that the facility will not run out of critical items.

To estimate the wound-care related costs in two hospitals in Denmark. A point-prevalence survey with a focus on resource consumption was carried out during a representative 1-week period in March 20 I 0, in two hospitals in Denmark: Regional Hospital Viborg, in the Viborg Municipality and Hillerod Hospital, in the Horsholm Municipality. Data were collected during a 2-day period for inpatients and outpatients in the hospitals and over a full week in the municipalities. The survey included information on the numbers, types and locations of the wounds, as well as resource consumption related to dressing changes. The estimation of costs was based on representative cost levels, including the salaries of health professionals or nurses and the cost of dressings and hospitalisation provided. In total, 33% (n=830) of inpatients had a wound. The majority of these were surgical/trauma wounds (25%), while pressure ulcers, leg ulcers and diabetic foot ulcers accounted for 3.3%, 1.7% and 1.6%, respectively. In the municipalities, there was a wound patient prevalence of 2.8 per I 000 population(I I I 000 acute wounds, 0.7/ I 000 pressure ulcers, 0.5/ I 000 leg ulcers and 0.3/ I 000 diabetic foot ulcers).The extrapolated figures for nurse time related to wound care per year was equivalent to I 0 full-time nurse positions in Hillerod Hospital, three in Viborg Hospital, 17 in Viborg Municipality and three in Horsholm Municipality. The total annual costs related to wound care was estimated as €3.6 million for Viborg Hospital, €4.1 million for Hillemd Hospital, € 1.2 million for Viborg Municipality and €232 548 for Horsholm Municipality, accounting for approximately 1.8% (Viborg), 1.6% (Hillerod), 2.4% (Viborg) and1.5% (Horsholm) of the total annual budgets. In the survey, 33% of the patients treated in the hospitals had a wound. Primary costs were defined as hospitalisation costs and nurse time related to dressing changes. Total annual costs of treatment, including hospitalisation, were estimated as approximately 1.6-1.8% for the hospitals and 1.5-2.4% for the municipalities. The level of costs support the relevance of increased efforts to secure better wound prevention and treatment to reduce the staff-time consumption and hospitalisation costs.

Penetrating injuries of the face.

1998-01-01

In dealing with gunshot wounds to the face, the emergency department physician should have a basic knowledge of ballistics. Securing an airway (either intubation or surgical airway) should be the top priority. The location of the wound dictates which patient should be intubated. Plain x-ray films of the face and skull, as well as CT scan in certain situations, allow determination of the extent of damages to the skeleton as well as intracranial injuries. Clinical symptoms suggesting an underlying vascular injury require an angiogram. After thorough debridement of the wounds, fractures are treated either with open-reduction and internal fixation or closed-reduction and intermaxillary fixation.

The use of firearms is becoming more prevalent in the society and hence the number of homicidal and suicidal cases. The severity of gunshot wounds varies depending on the weapons caliber and the distance of firing. Close-range, high-velocity gunshot wounds in the head and neck region can result in devastating esthetic and functional impairment. The complexity in facial skeletal anatomy cause multiple medical and surgical challenges to an operating surgeon, demanding elaborate soft and hard tissue reconstructions. Here we present the successful management of a patient shot by a low-velocity short-range pistol with basic life support measures, wound management, reconstruction, and rehabilitation.

Negative-pressure wound therapy and pulsed radiofrequency energy are two clinical modalities used to treat soft-tissue wounds. They are purported to affect healing differently. The aim of this experimental study was to contrast the two modalities at a mechanistic level and to investigate whether their combined therapy could achieve additive and complementary effects on wound healing. Full-thickness dorsal cutaneous wounds of diabetic, db/db, mice were treated with either negative-pressure wound therapy, pulsed radiofrequency energy, or combined therapies. Macroscopic healing kinetics were examined. Epidermal regeneration (proliferation rate and length of reepithelialization) and neovascularization (blood vessel density) were investigated. Messenger RNA levels indicative of angiogenic (basic fibroblast growth factor), profibrotic (transforming growth factor-β), epidermal proliferative (keratinocyte growth factor), and extracellular matrix remodeling (collagen 1) processes were measured in wound tissues. All three treatment groups displayed faster wound healing. The negative-pressure wound therapy/pulsed radiofrequency energy combined therapy led to significantly faster healing than either the negative-pressure wound therapy or pulsed radiofrequency energy therapy alone. Epidermal regeneration and neovascularization were enhanced in all three groups. The two negative-pressure wound therapy groups (alone and combined with pulsed radiofrequency energy) demonstrated more significant increases in expression of all assayed growth factors than the pulsed radiofrequency energy group. Furthermore, the combined therapy exhibited a more profound elevation in collagen 1 expression than either of the two therapies alone. Combining the negative-pressure wound therapy and pulsed radiofrequency energy modalities can achieve additive benefits in cutaneous healing, and the two therapies can be easily used together to complement each other in clinical wound treatments.

Different countries have different wound treatment traditions. We have studied the incidence and different factors related to infections in wound injuries sutured at a Norwegian A&E department. In this prospective study, clinical data were collected on 102 patients with traumatic wound injuries treated with sutures at Bergen Accident and Emergency Department between 30 February 2011 and 30 June 2011. Any wound infections in 97 of these patients at the time of suture removal were assessed and classified according to severity on a scale of grade 0 to grade 4. There were no serious infections, but mild clinical wound infections occurred in 15% of patients: 11% grade 1 and 4% grade 2 infections. Patients less than 65 years old had often cut themselves with knives (n = 33, 37%), and on their hands (n = 60, 67%), Men were most frequently injured at work (n = 38, 54%) and women most often at home (n = 18, 56%). No statistically significant correlation was found between the incidence of wound infections and the length of the wound, the time elapsed before suturing, the wound's location on the body, contamination or underlying chronic diseases. Two of the three self-inflictors in our study had clinical wound infections. Half of the bacteriological samples from ten of 15 wounds with clinical infection had plentiful growth of Staphylococcus aureus. One patient received oral antibiotic treatment for wound infection, and two had local antibiotic treatment. Mild clinical infections were found in almost one of six wounds sutured at a Norwegian A&E department. More studies are necessary to provide basic data to enable targeted improvements in wound treatment in the primary healthcare service.

Vibrational spectroscopy: a tool being developed for the noninvasive monitoring of wound healing

NASA Astrophysics Data System (ADS)

Crane, Nicole J.; Elster, Eric A.

2012-01-01

Wound care and management accounted for over 1.8 million hospital discharges in 2009. The complex nature of wound physiology involves hundreds of overlapping processes that we have only begun to understand over the past three decades. The management of wounds remains a significant challenge for inexperienced clinicians. The ensuing inflammatory response ultimately dictates the pace of wound healing and tissue regeneration. Consequently, the eventual timing of wound closure or definitive coverage is often subjective. Some wounds fail to close, or dehisce, despite the use and application of novel wound-specific treatment modalities. An understanding of the molecular environment of acute and chronic wounds throughout the wound-healing process can provide valuable insight into the mechanisms associated with the patient's outcome. Pathologic alterations of wounds are accompanied by fundamental changes in the molecular environment that can be analyzed by vibrational spectroscopy. Vibrational spectroscopy, specifically Raman and Fourier transform infrared spectroscopy, offers the capability to accurately detect and identify the various molecules that compose the extracellular matrix during wound healing in their native state. The identified changes might provide the objective markers of wound healing, which can then be integrated with clinical characteristics to guide the management of wounds.

Cost-effectiveness of becaplermin gel on wound healing of diabetic foot ulcers.

Gilligan, Adrienne M; Waycaster, Curtis R; Motley, Travis A

2015-01-01

We sought to determine the long-term cost effectiveness (payer's perspective) of becaplermin gel plus good wound care (BGWC) vs. good wound care (GWC) alone in terms of wound healing and risk of amputation in patients with diabetic foot ulcers (DFUs). Outcomes data were derived from a propensity score-matched cohort from the Curative Health Services database between 1998 and 2004, which was followed for 20 weeks. A four-state Markov model was used to predict costs and outcomes of wound healing and risk of amputation for BGWC vs. GWC alone over 1 year in patients with DFU. The primary outcome was closed-wound weeks. Transition probabilities for healing and amputation were derived from the aforementioned propensity score-matched cohorts. Ulcer recurrence was estimated from the medical literature. Utilization for becaplermin was calculated using the dosing algorithm in the product labeling. Of 24,898 eligible patients, 9.6% received BGWC. Based on the model, patients treated with BGWC had substantially more closed-wound weeks compared with GWC (16.1 vs. 12.5 weeks, respectively). More patients receiving BGWC had healed wounds at 1 year compared with those receiving GWC (48.1% vs. 38.3%). Risk of amputation was lower in the BGWC cohort (6.8% vs. 9.8%). Expected annual direct costs for DFU were $21,920 for BGWC and $24,640 for GWC. BGWC was economically dominant over GWC, providing better outcomes at a lower cost in patients with DFU. Compared with GWC alone, BGWC is more effective in healing wounds and lowering amputation risk, thereby decreasing long-term costs for DFU. © 2015 by the Wound Healing Society.

Difficult-to-heal and chronic wounds affect tens of millions of people worldwide. In the U.S. alone, the direct cost for their treatment exceeds $25 billion. Yet despite advances in wound research and treatment that have markedly improved patient care, wound healing is often delayed for weeks or months. For venous and diabetic ulcers, complete wound closure is achieved in as few as 25%–50% of chronic or hard-to-heal wounds. Wound bed preparation and the consistent application of appropriate and effective debridement techniques are recommended for the optimized treatment of chronic wounds. The TIME paradigm (Tissue, Inflammation/infection, Moisture balance and Edge of wound) provides a model to remove barriers to healing and optimize the healing process. While we often think of debridement as an episodic event that occurs in specific care giver/patient interface. There is the possibility of a maintenance debridement in which the chronic application of a medication can assist in both the macroscopic and microscopic debridement of a wound. We review the various debridement therapies available to clinicians in the United States, and explore the characteristics and capabilities of clostridial collagenase ointment (CCO), a type of enzymatic debridement, that potentially allows for epithelialization while debriding. It appears that in the case of CCO it may exert this influences by removal of the necrotic plug while promoting granulation and sustaining epithelialization. It is also easily combined with other methods of debridement, is selective to necrotic tissue, and has been safely used in various populations. We review the body of evidence has indicated that this concept of maintenance debridement, especially when combined episodic debridement may add a cost an efficacious, safe and cost-effective choice for debridement of cutaneous ulcers and burn wounds and it will likely play an expanding role in all phases of wound bed preparation.

Developing and integrating a practice model for health finance reform into wound healing programs: an examination of the triple aim approach.

PubMed

Flattau, Anna; Thompson, Maureen; Meara, Anne

2013-10-01

Throughout the United States, government and private payers are exploring new payment models such as accountable care organizations and shared savings agreements. These models are widely based on the construct of the Triple Aim, a set of three principles for health services reform: improving population-based outcomes, improving patient care experiences, and reducing costs through better delivery systems. Wound programs may adapt to the new health financing environment by incorporating initiatives known to promote the Triple Aim, such as diabetes amputation reduction and pressure ulcer prevention programs, and by rethinking how health services can best be delivered to meet these new criteria. The existing literature supports that programmatic approaches can improve care, quality, and cost, especially in the field of diabetic foot ulcers. Wound healing programs have opportunities to develop new business plan models that provide quality, cost-efficient care to their patient population and to be leaders in the development of new types of partnerships with payers and health delivery organizations.

The continuing problem of tetanus.

PubMed

Percy, A S; Kukora, J S

1985-04-01

Thirty-eight instances of tetanus were treated during a recent 20 year period at the University of Mississippi and Jackson Veterans Administration Medical Centers. One patient had received a single prior dose of tetanus toxoid and the remainder had never received tetanus toxoid. Sixteen patients sought medical care for their tetanus wound prior to the onset of clinical tetanus, but none received specific antitetanus prophylaxis. The majority of tetanus wounds were located on lower extremities and often were chronic vascular ulcers. The over-all mortality was 37 per cent and survival rate was not affected by patient age, duration, location or severity of the tetanus wound or presence of associated diseases. Aggressive surgical treatment of the tetanus wound was associated with decreased mortality for uncertain reasons. Although low mortality from tetanus is possible with improved intensive care technology, the disease should be virtually preventable by the provision of proper tetanus prophylaxis to all patients at risk.

We analyzed the production of reactive oxygen species (ROS) and of detoxifying enzymes and enzymes of the ascorbate (ASC) acid cycle in avocado fruit (Pesea Americana Mill cv Hass) in response to wounding. The levels of superoxide anion (O(2-), hydroxyl radicals (OH.) and hydrogen peroxide (H(2)O(2)) increased at 15 min and 2 and 15 h post-wounding. Peroxidase (POD) activity had increased to high levels 24 h after wounding; in contrast, catalase and superoxide dismutase (SOD) levels hat decreased significantly at 24 h post-treatment. Basic POD was the major POD form induced, and the levels of at least three apoplastic POD isozymes -increased following wounding. Using specific inhibitors, we characterized one MnSOD and two CuZnSOD isozymes. CuZnSOD activities decreased notably 12 h after treatment. The activities of dehydroascorbate reductase and glutathione reductase increased dramatically following the wounding treatment, possibly as a means to compensate for the redox changes due to ROS production.

Maxillofacial traumas caused by gunshot wounds may cause quite varied defects. The objective of this study was to evaluate the reconstruction methods in 12 patients with gunshot wound-related mandibular and maxillofacial bony and soft tissue defects. Twelve patients who were operated on for maxillofacial gunshot wounds at our clinic between 2002 and 2012 were included in the study. Seven patients were wounded in a suicide attempt, and 5 were wounded as a result of an accident or in assaults. Two patients underwent reconstruction using free fibula osteocutaneous flap, 4 patients received the free radial forearm osteocutaneous flap, 2 patients received costal bone graft, and 3 patients received iliac bone grafts. Satisfactory functional and aesthetic outcomes were achieved in cases where staged secondary reconstruction, balloon treatment, and consecutive fat and steroid injections into the depressed scar areas were applied. In conclusion, the basic goal in maxillofacial reconstruction is the functional and aesthetic reconstruction of the contours. Because it is not easy to get perfect results with only 1 clinical approach or 1 method, the proper timing and reconstruction method should be selected.

Reconstructive challenges in war wounds

PubMed Central

Bhandari, Prem Singh; Maurya, Sanjay; Mukherjee, Mrinal Kanti

2012-01-01

War wounds are devastating with extensive soft tissue and osseous destruction and heavy contamination. War casualties generally reach the reconstructive surgery centre after a delayed period due to additional injuries to the vital organs. This delay in their transfer to a tertiary care centre is responsible for progressive deterioration in wound conditions. In the prevailing circumstances, a majority of war wounds undergo delayed reconstruction, after a series of debridements. In the recent military conflicts, hydrosurgery jet debridement and negative pressure wound therapy have been successfully used in the preparation of war wounds. In war injuries, due to a heavy casualty load, a faster and reliable method of reconstruction is aimed at. Pedicle flaps in extremities provide rapid and reliable cover in extremity wounds. Large complex defects can be reconstructed using microvascular free flaps in a single stage. This article highlights the peculiarities and the challenges encountered in the reconstruction of these ghastly wounds. PMID:23162233

Wound botulism acquired in the Amazonian rain forest of Ecuador.

2006-04-01

Wound botulism results from colonization of a contaminated wound by Clostridium botulinum and the anaerobic in situ production of a potent neurotoxin. Between 1943, when wound botulism was first recognized, and 1990, 47 laboratory-confirmed cases, mostly trauma-associated, were reported in the United States. Since 1990, wound botulism associated with injection drug use emerged as the leading cause of wound botulism in the United States; 210 of 217 cases reported to the Centers for Disease Control and Prevention between 1990 and 2002 were associated with drug injection. Despite the worldwide distribution of Clostridium botulinum spores, wound botulism has been reported only twice outside the United States, Europe, and Australia. However, wound botulism may go undiagnosed and untreated in many countries. We report two cases, both with type A toxin, from the Ecuadorian rain forest. Prompt clinical recognition, supportive care, and administration of trivalent equine botulinum antitoxin were life-saving.

Dynamic Reciprocity in the Wound Microenvironment

Schultz, Gregory S.; Davidson, Jeffrey M.; Kirsner, Robert S.; Bornstein, Paul; Herman, Ira M.

2011-01-01

Here, we define dynamic reciprocity (DR) as an ongoing, bidirectional interaction amongst cells and their surrounding microenvironment. In the review, we posit that DR is especially meaningful during wound healing as the DR-driven biochemical, biophysical and cellular responses to injury play pivotal roles in regulating tissue regenerative responses. Such cell-extracellular matrix interactions not only guide and regulate cellular morphology, but cellular differentiation, migration, proliferation, and survival during tissue development, including e.g. embryogenesis, angiogenesis, as well as during pathologic processes including cancer diabetes, hypertension and chronic wound healing. Herein, we examine DR within the wound microenvironment while considering specific examples across acute and chronic wound healing. This review also considers how a number of hypotheses that attempt to explain chronic wound pathophysiology, which may be understood within the DR framework. The implications of applying the principles of dynamic reciprocity to optimize wound care practice and future development of innovative wound healing therapeutics are also briefly considered.

2010-06-01

While there is a consensus that clinical practice should be evidence based, this can be difficult to achieve due to confusion about the value of the various approaches to wound management. To address this, the European Wound Management Association (EWMA) set up a Patient Outcome Group whose remit was to produce recommendations on clinical data collection in wound care. This document, produced by the group and disseminated by JWC, identifies criteria for producing rigorous outcomes in both randomised controlled trials and clinical studies, and describes how to ensure studies are consistent and reproducible.

Current Status and Future of Skin Substitutes for Chronic Wound Healing.

PubMed

Nicholas, Mathew N; Yeung, Jensen

Chronic wounds, including diabetic ulcers, pressure ulcers, venous ulcers, and arterial insufficiency ulcers, are both difficult and expensive to treat. Conventional wound care may sometimes lead to suboptimal wound healing and significant morbidity and mortality for patients. The use of skin substitutes provides an alternative therapy showing superior efficacy and, in some cases, similar cost-effectiveness compared to traditional treatments. This review discusses the different types of currently available commercial skin substitutes for use in chronic wounds as well as the paucity of strong evidence supporting their use. It then delves into the limitations of these skin substitutes and examines the most recent research targeting these limitations.

The role of biofilms: are we hitting the right target?

PubMed

Wolcott, Randall; Dowd, Scot

2011-01-01

Chronic infections affect 17 million people yearly, and approximately 550,000 people die each year from, or with, their chronic infections. Acute and chornic infection differences are well known to clinicians, but the role of bacteria in producing these clinical differences remains poorly understood. This review relies on basic science, clinical studies, and a general review of the medical biofilm literature. The basic science studies are level A and B quality of evidence. The clinical studies are mainly retrospective cohort (level B) and case studies (level C). The biofilm literature includes reviews with varying levels of evidence. All articles have been peer reviewed and meet the standard of evidence-based medicine. Acute infections are associated with planktonic bacteria and must be diagnosed rapidly and accurately to prevent tissue damage and/or death. In contrast, biofilm behavior pursues a more parasitic course by producing sustained host hyperinflammation, with the biofilm feeding on plasma exudate. Chronic infections vacillate over long periods of time, responding only partially to antibiotics and reemerging once the antibiotics are withdrawn. Chronic wounds exhibit similar clinical behavior seen in other chronic infections and are associated with biofilm phenotype bacteria on their surface. Biofilm infections, such as chronic wounds, cannot be adequately diagnosed with current clinical cultures; therefore, molecular methods are necessary. Biofilm phenotype bacteria require multiple concurrent strategies, including débridement and targeted antibiofilm agents. Biofilm phenotype bacteria predominate on the surface of wounds, and biofilm-based management improves wound healing outcomes, indicating that biofilm is the right target for managing the bioburden barrier of chronic wounds.

Antenatal maternal education for improving postnatal perineal healing for women who have birthed in a hospital setting.

PubMed

O'Kelly, Sonia M; Moore, Zena Eh

2017-12-04

The female perineum becomes suffused and stretched during pregnancy, and further strain during vaginal childbirth contributes to approximately 85% of women experiencing some degree of trauma to the perineal region. Multiple factors play a role in the type and severity of trauma experienced, including parity, delivery method, and local practices. There is ongoing debate about best midwifery practice to reduce perineal trauma. Once perineal trauma has occurred, treatment also varies greatly, depending on its degree and severity, local practice and customs, and personal preference. In order to optimise wound-healing outcomes, it is important that wounds are assessed and managed in an appropriate and timely manner. A perineal wound may cause significant physical and/or psychological impact in the short or long term, however little evidence is available on this subject.Antenatal education serves to prepare women and their partners for pregnancy, delivery and the postpartum period. The delivery of this education varies widely in type, content, and nature. This review examined antenatal education which is specifically tailored towards perineal care and wound healing in the postnatal period via formal channels. Appropriate patient education positively impacts on wound-healing rates and compliance with wound care. Risk factors that contribute to the breakdown of wounds and poor healing rates may be addressed antenatally in order to optimise postnatal wound healing. It is important to assess whether or not antenatal wound-care education positively affects perineal healing, in order to empower women to incorporate best practice, evidence-based treatment with this important aspect of self-care in the immediate postnatal period. To evaluate the effects of antenatal education on perineal wound healing in postnatal women who have birthed in a hospital setting, and who have experienced a break in the skin of the perineum as a result of a tear or episiotomy, or both. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 September 2017), ClinicalTrials.gov (8th September 2017), the WHO International Clinical Trials Registry Platform (ICTRP) (8th September 2017) and reference lists of retrieved studies. We considered randomised controlled trials (RCTs) which referred to all formal methods of antenatal education and addressed care of a potential perineal wound as a result of a tear or episiotomy, which was experienced by pregnant women who planned to give birth within a hospital setting.Trials using a cluster-RCT and a quasi-randomised design would have been eligible for inclusion in this review but none were identified. Cross-over trials were not eligible for inclusion in this review. Studies published in abstract form would have been eligible for inclusion in this review, but none were identified.We planned to consider all formal methods of antenatal education which addressed care of a perineal wound. We also planned to consider all contact points where there was an opportunity for formal education, including midwifery appointments, antenatal education classes, obstetrician appointments, general practitioner appointments and physiotherapist appointments. Two review authors independently assessed titles and abstracts of the studies identified by the search strategy for their eligibility. No studies met the inclusion criteria for this review. We excluded one study and one other study is ongoing. We set out to evaluate the RCT evidence pertaining to the impact of antenatal education on perineal wound healing in postnatal women who have birthed in a hospital setting, and who experienced a break in the skin of the perineum as a result of a tear or episiotomy, or both. However, no studies met the inclusion criteria. There is a lack of evidence concerning whether or not antenatal education relating to perineal wound healing in this cohort of women will change the outcome for these women in relation to wound healing, infection rate, re-attendance or re-admission to hospital, pain, health-related quality of life, maternal bonding, and negative emotional experiences. Further study is warranted in this area given the significant physical, psychological and economic impact of perineal wounds, and the large proportion of childbearing women who have experienced a postnatal wound. The benefits of any future research in this field would be maximised by incorporating women in a range of socio-economic groups, and with a range of healthcare options. This research could take both a qualitative and a quantitative approach and examine the outcomes identified in this review in order to assess fully the potential benefits of a tailored antenatal package, and to make recommendations for future practice. There is currently no evidence to inform practice in this regard.

Managing painful chronic wounds: the Wound Pain Management Model.

PubMed

Price, Patricia; Fogh, Karsten; Glynn, Chris; Krasner, Diane L; Osterbrink, Jürgen; Sibbald, R Gary

2007-04-01

Chronic wound pain is not well understood and the literature is limited. Six of 10 patients venous leg ulcer experience pain with their ulcer, and similar trends are observed for other chronic wounds. Chronic wound pain can lead to depression and the feeling of constant tiredness. Pain related to the wound should be handled as one of the main priorities in chronic wound management together with addressing the cause. Management of pain in chronic wounds depends on proper assessment, reporting and documenting patient experiences of pain. Assessment should be based on six critical dimensions of the pain experience: location, duration, intensity, quality, onset and impact on activities of daily living. Holistic management must be based on a safe and effective mix of psychosocial approaches together with local and systemic pain management. It is no longer acceptable to ignore or inadequately document persistent wound pain and not to develop a treatment and monitoring strategy to improve the lives of persons with chronic wounds. Unless wound pain is optimally managed, patient suffering and costs to health care systems will increase.

Honey in wound care: effects, clinical application and patient benefit.

PubMed

Lay-flurrie, Karen

The use of honey in wound management has enjoyed a resurgence. This is largely due to the growing clinical problem of antibiotic-resistant bacteria and the combined difficulties for the practitioner in managing chronic wound types, such as burns, leg ulcers or surgical wounds, that may become infected, for example, with methicillin-resistant Staphylococcus aureus or Pseudomonas. The associated costs of treating such wounds are escalating as a result. While the use of honey as a wound dressing has been recognized, at least since Egyptian times circa 2000 BC, it is only more recently, due to the development and licensing of modern honey wound dressings, that such dressings have become more widely available and used in wound management. This article focuses on the use of honey in the treatment of infected wounds and burns. It will examine the effects of honey at the wound bed and its clinical applications, along with the current dressings available. Also discussed are the practical considerations, if, like any wound dressing, honey is to be used safely, appropriately and for the benefit of the patient.

Benefits of applying low-temperature plasma treatment to wound care and hemostasis from the viewpoints of physics and pathology

Over the last decade, low-temperature plasma (LTP) technology has reached the life sciences and introduced the benefits of using such technology at atmospheric pressure for medical applications. The active elements from LTP, such as reactive molecular species, charged particles and photons, appear to react with biomolecules on wounds and at bleeding points. This action by LTP might be analogous with semiconductor fabrication techniques such as etching and surface modification. From this perspective, we discuss the general aspects and principles of LTP devices used at atmospheric pressure in wound care and hemostasis as an interdisciplinary fusion of applied physics and pathology.

Debridement and wound bed preparation.

PubMed

Falabella, Anna F

2006-01-01

Debridement can play a vital role in wound bed preparation and the removal of barriers that impair wound healing. In accordance with the TIME principles, debridement can help remove nonviable tissue, control inflammation or infection, decrease excess moisture, and stimulate a nonadvancing wound edge. There are many types of debridement, each with a set of advantages and disadvantages that must be clearly understood by the healthcare team. Failure to use the correct debridement method for a given type of wound may lead to further delays in healing, increase patient suffering, and unnecessarily increase the cost of care. This review article discusses the various methods of debridement, describes currently available debriding agents, evaluates the clinical data regarding their efficacy and safety, and describes strategies for the management of problematic nonhealing wounds.

Clinical approach to wounds: débridement and wound bed preparation including the use of dressings and wound-healing adjuvants.

Attinger, Christopher E; Janis, Jeffrey E; Steinberg, John; Schwartz, Jaime; Al-Attar, Ali; Couch, Kara

2006-06-01

This is a clinical review of current techniques in wound bed preparation found to be effective in assisting the wound-healing process. The process begins with the identification of a correct diagnosis of the wound's etiology and continues with optimizing the patient's medical condition, including blood flow to the wound site. Débridement as the basis of most wound-healing strategies is then emphasized. Various débridement techniques, including surgery, topical agents, and biosurgery, are thoroughly discussed and illustrated. Wound dressings, including the use of negative pressure wound therapy, are then reviewed. To properly determine the timing of advance therapeutic intervention, the wound-healing progress needs to be monitored carefully with weekly measurements. A reduction in wound area of 10 to 15 percent per week represents normal healing and does not mandate a change in the current wound-healing strategy. However, if this level of wound area reduction is not met consistently on a weekly basis, then alternative healing interventions should be considered. There is a growing body of evidence that can provide guidance on the appropriate use of such adjuvants in the problem wound. Several adjuvants are discussed, including growth factor, bioengineered tissues, and hyperbaric medicine.

The Role of Chemokines in Fibrotic Wound Healing

PubMed Central

Ding, Jie; Tredget, Edward E.

2015-01-01

Significance: Main dermal forms of fibroproliferative disorders are hypertrophic scars (HTS) and keloids. They often occur after cutaneous wound healing after skin injury, or keloids even form spontaneously in the absence of any known injury. HTS and keloids are different in clinical performance, morphology, and histology, but they all lead to physical and psychological problems for survivors. Recent Advances: Although the mechanism of wound healing at cellular and tissue levels has been well described, the molecular pathways involved in wound healing, especially fibrotic healing, is incompletely understood. Critical Issues: Abnormal scars not only lead to increased health-care costs but also cause significant psychological problems for survivors. A plethora of therapeutic strategies have been used to prevent or attenuate excessive scar formation; however, most therapeutic approaches remain clinically unsatisfactory. Future Directions: Effective care depends on an improved understanding of the mechanisms that cause abnormal scars in patients. A thorough understanding of the roles of chemokines in cutaneous wound healing and abnormal scar formation will help provide more effective preventive and therapeutic strategies for dermal fibrosis as well as for other proliferative disorders.

2016-03-01

In military medicine, one of the challenges in dealing with large combat-related injuries is the prevalence of bacterial infection, including multidrug resistant organisms. This can prolong the wound healing process and lead to wound dehiscence. Current methods of identifying bacterial infection rely on culturing microbes from patient material and performing biochemical tests, which together can take 2-3 days to complete. Surface Enhanced Raman Spectroscopy (SERS) is a powerful vibrational spectroscopy technique that allows for highly sensitive structural detection of analytes adsorbed onto specially prepared metal surfaces. In the past, we have been able to discriminate between bacterial isolates grown on solid culture media using standard Raman spectroscopic methods. Here, SERS is utilized to assess the presence of bacteria in wound effluent samples taken directly from patients. To our knowledge, this is the first attempt for the application of SERS directly to wound effluent. The utilization of SERS as a point-of-care diagnostic tool would enable physicians to determine course of treatment and drug administration in a matter of hours.

Marjolin's Ulcer Complicating a Pressure Sore: The Clock is Ticking.

2016-02-22

Malignant degeneration in any chronic wound is termed a Marjolin's ulcer (MU). The overall metastatic rate of MU is approximately 27.5%. However, the prognosis of MU specific to pressure sores is poor, with a reported metastatic rate of 61%. This is due to insidious, asymptomatic malignant degeneration, a lack of healthcare provider awareness, and, ultimately, delayed management. An 85-year-old white male was noted by his wound-care nurse to have a rapidly developing growth on his lower back over a period of 4 months. There was history of a non-healing, progressive pressure ulcer of the lower back for the past 10 years. On examination, there was a 4 × 4 cm pressure ulcer of the lower back, with a superimposed 1.5 × 2 cm growth in the superior region. There was an absence of palpable regional lymphadenopathy. Punch biopsy revealed squamous cell carcinoma consistent with Marjolin's ulcer. The ulcer underwent excision with wide margins, and a skin graft was placed. Due to the prompt recognition of an abnormality by the patient's wound-care nurse, metastasis was not evident on imaging. There are no signs of recurrence at 1-year follow-up. Marjolin's ulcer has a rapid progression from local disease to widespread metastasis. Therefore, it is essential that wound-care providers are aware of the clinical signs and symptoms of malignant degeneration in chronic wounds.

Ward nurses' use of wound dressings before and after a bespoke education programme.

A survey of ward nurses in medical, surgical, orthopaedic and rehabilitation specialties in relation to their care of wounds and their choice and use of wound dressings was carried out in May and August 2009 at St Mary's Hospital. Isle of Wight, UK. The objectives were to find out the distribution of wound types, and their characteristics, that were treated by ward nurses in the hospital, and to assess clinical practice in the use of wound dressings, before and after a bespoke programme of education and training. A visual framework to aid the ward nurses in the choice of dressings and frequency of change was introduced after the May 2009 survey. Following the nurses' education and training programme a repeat survey, using the same methodology, was conducted in August 2009. In the initial survey, 172 wounds were included (mean number of wounds per patient 1.64) and in the repeat one, 159 (mean number of wounds per patient 1.54). In both phases of the survey, the most common wound type was pressure ulcers, followed by surgical wounds; over 60% of the wounds were pressure ulcers, of which around half were category 1, and one-third were category 2. No category 4 ulcers were recorded. About one-third of the wounds had a duration of more than 21 days. On average, wound dressings were left in place for between two and three days, with 35% of dressings being changed on a daily basis. The mean cost of dressings per wound per week was observed to be lower in the repeat survey than in the initial one (£9.02 and £11.23 respectively). The number of undesirable reasons for changing the dressing was lower in the second phase than the first. The methodology of the surveys provided meaningful and valuable results over a short timescale, and increased understanding of wound types, their characteristics, and clinical practice. The surveys showed that data that can be collected in a short period using a simple tool can yield complex and revealing data trends. They also showed that an education programme followed by a re-survey can improve practice and reduce the costs of wound care.

The Utility and Versatility of Perforator-Based Propeller Flaps in Burn Care.

Teven, Chad M; Mhlaba, Julie; O'Connor, Annemarie; Gottlieb, Lawrence J

The majority of surgical burn care involves the use of skin grafts. However, there are cases when flaps are required or provide superior outcomes both in the acute setting and for postburn reconstruction. Rarely discussed in the context of burn care, the perforator-based propeller flap is an important option to consider. We describe our experience with perforator-based propeller flaps in the acute and reconstructive phases of burn care. We reviewed demographics, indications, operative details, and outcomes for patients whose burn care included the use of a perforator-based propeller flap at our institution from May 2007 to April 2015. Details of the surgical technique and individual cases are also discussed. Twenty-one perforator-based propeller flaps were used in the care of 17 burn patients. Six flaps (29%) were used in the acute phase for coverage of exposed joints, tendons, cartilage, and bone; coverage of open wounds; and preservation of range of motion (ROM) by minimizing scar contracture. Fifteen flaps (71%) were used for reconstruction of postburn deformities including coverage of chronic wounds, for coverage after scar contracture release, and to improve ROM. The majority of flaps (94% at follow-up) exhibited stable soft tissue coverage and good or improved ROM of adjacent joints. Three cases of partial flap loss and one case of total flap loss occurred. Perforator-based propeller flaps provide reliable vascularized soft tissue for coverage of vital structures and wounds, contracture release, and preservation of ROM across joints. Despite a relatively significant risk of minor complications particularly in the coverage of chronic wounds, our study supports their utility in both the acute and reconstructive phases of burn care.

Pressure ulcer prevention and management strategies in Turkey.

Pressure ulcers are a serious problem that can lead to pain and delayed recovery. In Turkey, the selection of dressing products is usually left to the nurse managing the patient and depends on several factors, including the condition of the wound, the nurse's knowledge, and the nurse's experience. The aim of this study was to determine prevention and management strategies for pressure ulcer care in hospitalized patients in Turkey and to identify the factors that influence the selection of products by nurses. The descriptive study was carried out in various departments (orthopedic, neurological, oncology, and intensive care) where bedridden patients were found. A total of 110 nurses volunteered to participate. Data were collected by means of a questionnaire developed after a review of the literature. Only 32% of the nurses made use of a pressure ulcer care risk evaluation scale (Norton scale), and air mattresses were used by 89% as a preventive measure with patients who were at risk. When pressure ulcers occurred, advanced wound care products were preferred by most of the nurses. Seventy four percent of nurses considered the condition of wound for selection of products. Despite correctly noting several strategies for prevention of pressure ulcers, 9% of nurses also described massage around boney prominence and the use of inflatable rings as effective preventive strategies. This descriptive study shows that nurses in Turkey are primarily responsible for prevention and management of pressure ulcer care and that both traditional dressing products and advanced wound care products are used in the care of all stages of pressure ulcers in Turkey. It also illustrates the need for ongoing pressure ulcer education to promote evidence-based practice and reduce the use of ineffective (or harmful) strategies.

Patients with advanced illnesses show the highest prevalence for pressure injuries. In the palliative care setting, the ultimate goal is injury healing, but equally important is wound maintenance, wound palliation (wound-related pain and symptom management), and primary and secondary wound prevention. To describe the course of healing for pressure injuries in a home palliative care setting according to different end-points, and to explore patient and caregiver characteristics and specific care activities associated with their achievement. Four-year retrospective chart review of 669 patients cared for in a home palliative care service, of those 124 patients (18.5%) had at least one pressure injury with a survival rate less than or equal to six months. The proportion of healed pressure injuries was 24.4%. Of the injuries not healed, 34.0% were in a maintenance phase, whereas 63.6% were in a process of deterioration. Body mass index (P = 0.0014), artificial nutrition (P = 0.002), and age <70 years (P = 0.022) emerged as predictive factors of pressure injury complete healing. Artificial nutrition, age, male caregiver (P = 0.034), and spouse (P = 0.036) were factors significantly associated with a more rapid pressure injury healing. Continuous deep sedation was a predictive factor for pressure injury deterioration and significantly associated with a more rapid worsening. Pressure injury healing is a realistic aim in home palliative care, particularly for injuries not exceeding Stage II occurring at least two weeks before death. When assessing pressure injuries, our results highlight the need to also pay attention to artificial nutrition, continuous deep sedation, and the caregiver's role and gender.

A review of topical negative pressure therapy in wound healing: sufficient evidence?

PubMed

Mouës, C M; Heule, F; Hovius, S E R

2011-04-01

Topical negative pressure (TNP) therapy has become a useful adjunct in the management of various types of wounds. However, the TNP system still has characteristics of a "black box" with uncertain efficacy for many users. We extensively examined the effectiveness of TNP therapy reported in research studies. A database search was undertaken, and over 400 peer-reviewed articles related to the use of TNP therapy (animal, human, and in vitro studies) were identified. Almost all encountered studies were related to the use of the commercial VAC device (KCI Medical, United States). Mechanisms of action that can be attributed to TNP therapy are an increase in blood flow, the promotion of angiogenesis, a reduction of wound surface area in certain types of wounds, a modulation of the inhibitory contents in wound fluid, and the induction of cell proliferation. Edema reduction and bacterial clearance, mechanisms that were attributed to TNP therapy, were not proven in basic research. Copyright © 2011 Elsevier Inc. All rights reserved.

Buruli ulcer (BU) is a skin infection caused by Mycobacterium ulcerans. The wounds of most BU patients are colonized with different microorganisms, including Staphylococcus aureus. This study investigated possible patient-to-patient transmission events of S. aureus during wound care in a health care center. S. aureus isolates from different BU patients with overlapping visits to the clinic were whole-genome sequenced and analyzed by a gene-by-gene approach using SeqSphere(+) software. In addition, sequence data were screened for the presence of genes that conferred antibiotic resistance. SeqSphere(+) analysis of whole-genome sequence data confirmed transmission of methicillin resistant S. aureus (MRSA) and methicillin susceptible S. aureus among patients that took place during wound care. Interestingly, our sequence data show that the investigated MRSA isolates carry a novel allele of the fexB gene conferring chloramphenicol resistance, which had thus far not been observed in S. aureus.

Smoking, chronic wound healing, and implications for evidence-based practice.

Chronic wounds are rising in prevalence and creating significant socioeconomic burdens for patients and healthcare systems worldwide. Therefore, it is now more important than ever that clinicians follow evidence-based guidelines for wound care when developing personalized treatment plans for their patients with chronic wounds. Evidence-based guidelines for treating venous leg ulcers, diabetic foot ulcers, and pressure ulcers, the 3 main categories of chronic wounds, focus primarily on biologic therapies. However, there are also evidence-based guidelines for treating behavioral risks to poor healing, such as smoking, which should be incorporated into treatment plans when appropriate. The purpose of this article was to review the mechanisms through which smoking adversely impacts the wound healing process, and propose strategies for incorporating evidence-based guidelines for treating tobacco dependence into treatment plans for patients with chronic wounds who smoke.

Evaluating a native collagen matrix dressing in the treatment of chronic wounds of different aetiologies: a case series.

PubMed

Ricci, E; Cutting, K F

2016-11-02

To collate clinical evidence on the use of a native collagen matrix dressing, consisting of a fibrillary collagen network, in patients with a variety of chronic wounds. Patients whose wounds had not improved in the eight weeks before the beginning of the evalutaion were recruited. All participants had their dressings changed twice weekly and received standard adjunctive wound care as part of their treatment. Data, collected over a 4-week period, included: patient demographics, wound surface area measurements, Bates-Jensen score, level of wound pain, wound infection status, wound bed preparation staging score, depth of wound according to tissue type, and photographic imaging of patients' wounds. We recruited 19 patients with 20 wounds and a mean wound duration of 66.6 months (range: 4-480 months). There was a mean decrease in wound surface area of 29% (median reduction: 47%). A reduction in the Bates-Jensen score was demonstrated in 85% of cases. Wound pain reduced by 66.66% and the wound bed preparation score reduced in 16 wounds with four remaining static. No adverse events arose. This case series provides clinical evidence on the use of a native collagen matrix dressing in the management of hard-to-heal wounds that have previously received local standard therapy. The decrease in wound surface area together with other data indicating improved wound status suggests that a native collagen matrix dressing supports healing and improves quality of life through reduction in wound pain.

Wound treatment and pain management: a stressful time.

Matsuzaki, Kyoichi; Upton, Dominic

This review and case study report considers the evidence to indicate that the progress of wound healing is negatively affected by the presence of stressors and in circumstances where patients are in pain. It considers the relationship between perceptions of pain, stress and delayed wound healing with a specific focus on guidance for clinical practice. It is appreciated that although the literature has examined these issues in the management of acute wounds, demonstrating that psychological stress can have detrimental effects on the wound-healing process, the evidence to support this link in relation to chronic wounds is limited. The review considers evidence indicating that punch biopsy wounds heal more slowly in subjects under stress on account of caring for family members with long-term illnesses and also considers briefly the relationship between cortisol secretion in response to stress and the consequent influences on cytokine levels and the wound-healing process. © 2012 The Authors.

Basic research, exploring the hypothesis that 2-(ω-carboxyethyl)pyrrole (CEP) modifications of proteins are generated nonenzymatically in vivo is delivering a bonanza of molecular mechanistic insights into age-related macular degeneration, autism, cancer, and wound healing. CEPs are produced through covalent modification of protein lysyl ε-amino groups by γ-hydroxyalkenal phospholipids that are formed by oxidative cleavage of docosahexaenate-containing phospholipids. Chemical synthesis of CEP-modified proteins and the production of highly specific antibodies that recognize them preceded and facilitated their detection in vivo and enabled exploration of their biological occurrence and activities. This investigational approach –from the chemistry of biomolecules to disease phenotype – is proving to be remarkably productive. PMID:21875030

A fast and effective wound healing process would substantially decrease medical costs, wound care supplies, and hospitalization significantly improving the patients’ quality of life. The search for effective therapeutic approaches seems to be imperative in order to avoid the aggravation of chronic wounds. In spite of all the efforts that have been made during the recent years towards the development of artificial wound dressings, none of the currently available options combine all the requirements necessary for quick and optimal cutaneous regeneration. Therefore, technological advances in the area of temporary and permanent smart dressings for wound care are required. The development of nanoscience and nanotechnology can improve the materials and designs used in topical wound care in order to efficiently release antimicrobial, anti-inflammatory and regenerative compounds speeding up the endogenous healing process. Nanostructured dressings can overcome the limitations of the current coverings and, separately, natural origin components can also overcome the drawbacks of current antibiotics and antiseptics (mainly cytotoxicity, antibiotic resistance, and allergies). The combination of natural origin components with demonstrated antibiotic, regenerative, or anti-inflammatory properties together with nanostructured materials is a promising approach to fulfil all the requirements needed for the next generation of bioactive wound dressings. Microbially compromised wounds have been treated with different essential oils, honey, cationic peptides, aloe vera, plant extracts, and other natural origin occurring antimicrobial, anti-inflammatory, and regenerative components but the available evidence is limited and insufficient to be able to draw reliable conclusions and to extrapolate those findings to the clinical practice. The evidence and some promising preliminary results indicate that future comparative studies are justified but instead of talking about the beneficial or inert effects of those natural origin occurring materials, the scientific community leads towards the identification of the main active components involved and their mechanism of action during the corresponding healing, antimicrobial, or regenerative processes and in carrying out systematic and comparative controlled tests. Once those natural origin components have been identified and their efficacy validated through solid clinical trials, their combination within nanostructured dressings can open up new avenues in the fabrication of bioactive dressings with outstanding characteristics for wound care. The motivation of this work is to analyze the state of the art in the use of different essential oils, honey, cationic peptides, aloe vera, plant extracts, and other natural origin occurring materials as antimicrobial, anti-inflammatory and regenerative components with the aim of clarifying their potential clinical use in bioactive dressings. We conclude that, for those natural occurring materials, more clinical trials are needed to reach a sufficient level of evidence as therapeutic agents for wound healing management. PMID:28793497

The Use of Biologic Scaffolds in the Treatment of Chronic Nonhealing Wounds

PubMed Central

Turner, Neill J.; Badylak, Stephen F.

2015-01-01

Significance: Injuries to the skin as a result of illness or injury, particularly chronic nonhealing wounds, present a major healthcare problem. Traditional wound care approaches attempt to control the underlying causes, such as infection and ischemia, while the application of wound dressings aims to modify a poorly healing wound environment into a microenvironment more closely resembling an acute wound allowing the body to heal the wound naturally. Recent Advances: Regenerative medicine approaches, such as the use of biologic scaffold materials comprising an intact extracellular matrix (ECM) or individual components of the ECM, are providing new therapeutic options that focus upon the provision of biochemical cues that alter the wound microenvironment to facilitate rapid restoration of normal skin architecture. Critical Issues: The incidence of chronic nonhealing wounds continues to increase. For example, between 15% and 20% of diabetics are likely to develop chronic, nonhealing foot wounds creating an increasing burden on healthcare systems worldwide. Future Directions: Developing a thorough understanding of wound microenvironment and the mechanisms by which biologic scaffolds work in vivo has the potential to markedly improve outcomes in the clinical translation for the treatment of chronic wounds.

Advances in tissue preservation have led to the commercialization of human placental membranes for the purposes of wound management with each product being characterized by different compositions and properties. The a priori specification of the research question in this investigator-initiated study focused on the clinical outcomes in two nonrandomized, however statistically equal and homogenous patient cohorts receiving either a viable intact cryopreserved human placental membrane (vCPM) or a dehydrated human amnion/chorion membrane (dHACM), for the management of wounds at a single center. A total of 79 patients with 101 wounds were analyzed: 40 patients with 46 wounds received vCPM and 39 patients with 55 wounds received dHACM. The proportion of wounds achieving complete wound closure was 63.0% (29/46) for vCPM and 18.2% (10/55) for dHACM (p < 0.0001) for all treated wounds combined. This is the first comparative effectiveness study to report on the clinical outcomes associated with the use of different placental wound care products once broadly implemented in the clinical setting. © 2016 The Authors.

To analyze the impact of actions organized by a quality of care improvement team on the use of sedatives when treating wounds in children under the age of 5 years. Quasiexperimental pre/post study enrolling children under the age of 5 years brought to a pediatric emergency department with wounds requiring surgical repair with suturing. A team to promote the use of sedation in such minor procedures in these children was established. The team organized the following interventions: training workshops, development and circulation of a sedation protocol, and establishment of a computerized alert. The first analysis of results was done at 2 months and the second at 9 months. The quality of care indicators, the use of sedatives while wounds were treated in children, was analized in 2 age groups: (under the age of 2 years and between 2 and 5 years) and results were compared with the preintervention phase. A total of 22 958 emergencies were registered in children under 5 years old; 548 (2.4%) involved uncomplicated wounds. Of the 548 patients, 350 (63.8%) required surgical repair, 75 of them (21.4%) in children under the age of 2 years. Ten percent of these children had received a sedative in the period before the team's intervention; 22% had been sedated at the 2-month analysis and 31.4% at 9 months (P<.01). For children between 2 and 5 years old, the percentages were 4.4% (pre-intervention), 10% (2 months), and 25% (9 months) (P<.01). Eighty-two percent of the families and 69% of the physicians thought that anxiety was adequately controlled. Actions designed by a multidisciplinary quality of care team are effective for increasing the use of sedatives while wounds are treated in children under the age of 5 years.

Cost-effectiveness of using Polyheal compared with surgery in the management of chronic wounds with exposed bones and/or tendons due to trauma in France, Germany and the UK.

The objective of this study was to assess the cost-effectiveness of Polyheal compared with surgery in treating chronic wounds with exposed bones and/or tendons (EB&T) due to trauma in France, Germany and the UK, from the perspective of the payers. Decision models were constructed depicting the management of chronic wounds with EB&T and spanned the period up to healing or up to 1 year. The models considered the decision by a plastic surgeon to treat these wounds with Polyheal or surgery and was used to estimate the relative cost-effectiveness of Polyheal at 2010/2011 prices. Using Polyheal instead of surgery is expected to increase the probability of healing from 0·93 to 0·98 and lead to a total health-care cost of €7984, €7517 and €8860 per patient in France, Germany and the UK, respectively. Management with surgery is expected to lead to a total health-care cost of €12 300, €18 137 and €11 330 per patient in France, Germany and the UK, respectively. Hence, initial treatment with Polyheal instead of surgery is expected to lead to a 5% improvement in the probability of healing and a substantial decrease in health-care costs of 35%, 59% and 22% in France, Germany and the UK, respectively. Within the models' limitations, Polyheal potentially affords the public health-care system in France, Germany and the UK a cost-effective treatment for chronic wounds with EB&T due to trauma, when compared with surgery. However, this will be dependent on Polyheal's healing rate in clinical practice when it becomes routinely available. © 2013 The Authors.

Open Loop Structure Low Cost Integrated Differential Inductive Micro Magnetic Volumetric Bio-Sensors

NASA Astrophysics Data System (ADS)

Khodadadi, Mohammad; Chang, Long; Litvinov, Dimitri

This investigation proposes a study, model, simulate and experiment innovative very low cost Magnetic induction biosensor for point of care diagnostics. The biosensor consists of 2 ``semi-loops'' in a micro fluidic channel, one as a sensor and one as a reference, the design takes advantage of microfabrication processes to produce more precise structures to improve sensitivity. Besides the attractively low cost, this biosensor has many advantages. Since the detector is basically a shaped wire, it is inherently robust and reliable. Typical errors in fabricating the wires will not affect its performance and it is sensing volumetric, unlike GMR-based sensors used in biosensor systems that boast single particle detection. Due to small dimensions the sensors do not need to be calibrated. This sensor also has a large range of detection since its sensitivity is proportional to the excitation frequency. Being able to sense Magnetic nano particles in the volume is an advantage in term of trapping MNPs and sensitivity and functionality. Basically, this new brilliant design, fill the gap between the fabricated sensors and hand wounded sensors.

Acute wounds do not generally require professional treatment modalities and heal in a predictable fashion, but chronic wounds are mainly accompanied with infection and prolonged inflammation, leading to healing impairments and continuous tissue degradation. Although a vast amount of products have been introduced in the market, claiming to provide a better optimization of local and systemic conditions of patients, they do not meet the expectations due to being expensive and not easily accessible, requiring wound care facilities, having patient-specific response, low efficiency, and severe side-effects. In this sense, developing new, safe, self-applicable, effective, and cheap wound care products with broad-range antimicrobial activity is still an attractive area of international research. In the present work, boron derivatives [boric acid and sodium pentaborate pentahydrate (NaB)] were evaluated for their antimicrobial activity, proliferation, migratory, angiogenesis, gene, and growth factor expression promoting effects on dermal cells in vitro. In addition, boron-containing hydrogel formulation was examined for its wound healing promoting potential using full-thickness wound model in streptozotocin-induced diabetic rats. The results revealed that while both boron compounds significantly increased proliferation, migration, vital growth factor, and gene expression levels of dermal cells along with displaying remarkable antimicrobial effects against bacteria, yeast, and fungi, NaB displayed greater antimicrobial properties as well as gene and growth factor expression inductive effects. Animal studies proved that NaB-containing gel formulation enhanced wound healing rate of diabetic animals and histopathological scores. Overall data suggest a potential promising therapeutic option for the management of chronic wounds but further studies are highly warranted to determine signaling pathways and target metabolisms in which boron is involved to elucidate the limitations and extend its use in clinics.

Hyperosmotic nanoemulsions: Development and application of a new antimicrobial treatment for wound care

NASA Astrophysics Data System (ADS)

Connell, Sean

Wound healing is the intricate process that restores function to damaged skin. The process consists of the inflammatory, proliferative and remodeling phases that orchestrate dynamic cellular responses to regenerate the cutaneous barrier. However, microbial contamination of the wound site stimulates a deleterious inflammatory response with the production of endotoxins, exotoxins and proteases that result in secondary injury. The end result is delayed healing, protracted debilitation and increased health care costs. Controlling contamination is critical for proper wound management and reduced burden on the healthcare system. Based on this concern, we developed and applied a new antimicrobial therapeutic that relies on hyperosmotic nanoemulsions (HNE). The biomechanical process consists of a high-energy nanoemulsion component that permeates the protective microbial membrane and a (ii) nonionic hyperosmoticum that facilitates intracellular water extraction to critically dehydrate the pathogen. HNE was shown to be effective against a multitude of pathogens including bacteria, antibiotic-resistant variants, fungi and viruses. Reported non-clinical studies demonstrate that the membrane disrupting nanoemulsion and hyperosmotic component act synergistically to enhance microbicidal activity. Further, results illustrate that pathogen inactivation was rapid as determined by ion and macromolecule leakage assays. Application of HNE in a pre-clinical animal model of wound healing demonstrated the treatment actively promoted healing to reduce treatment times. HNE mitigated wound infection to reduce the inflammatory response and mechanically debrided the wound to facilitate wound closure. Recent work further enhanced the stability of the nanoemulsion component with the addition of surfactant stabilizers using a low-energy spontaneous emulsification process. The refined nanoemulsion composition was stable against physical stressors and long-term storage without disrupting the intrinsic antimicrobial attributes. The reported findings have key implications for the development and application of a new antimicrobial therapeutic platform for wound management.

Infection in Venous Leg Ulcers: Considerations for Optimal Management in the Elderly.

PubMed

Pugliese, Douglas J

2016-02-01

Venous leg ulcers are the most common cause of chronic leg wounds, accounting for up to 70 % of all chronic leg ulcers and carrying with them a significant morbidity, especially for elderly patients. Among people aged 65 years and older, the annual prevalence is 1.7 %. Billions of dollars per year are spent caring for patients with these often difficult-to-heal and sometimes recurrent chronic wounds. Chronic non-healing wounds of the lower extremities are susceptible to microbial invasion and can lead to serious complications, such as delayed healing, cellulitis, enlargement of wound size, debilitating pain, and deeper wound infections causing systemic illness. Recognition and treatment of the infected venous leg ulcer is an essential skill set for any physician caring for geriatric patients. Most physicians rely on subjective clinical signs and patient-reported symptoms in the evaluation of infected chronic wounds. The conventional bacterial culture is a widely available tool for the diagnosis of bacterial infection but can have limitations. Systemic antibiotics, as well as topical antiseptics and antibiotics, can be employed to treat and control infection and critical colonization. Better understanding of microbial biofilms in the wound environment have caused them to emerge as an important reason for non-healing and infection due to their increased resistance to antimicrobial, immunological, and chemical attack. A sound understanding of the microbial-host environment and its complexities, as well as the pathophysiology of venous hypertension, must be appreciated to understand the need for a multimodality approach to treating an infected venous leg ulcer. Other treatment measures are often required, in addition to systemic and topical antibiotics, such as the application of wound bandages, compression therapy, and wound debridement, which can hasten clearance of the infection and help to promote healing.

Chronic wound infections impose major medical and economic costs on health-care systems, cause significant morbidity, mortality and prolonged hospitalisation. The presence of biofilm producing bacteria in these wounds is considered as an important virulence factor that leads to chronic implications including ulceration. The undertaken study aimed to isolate and identify the biofilm aerobic bacterial pathogens from patients with chronic wound infections, and determine their antibiotics resistance profiles Method: During this study, swab specimens were collected from patients with chronic wounds at teaching hospitals of Peshawar, Pakistan between May 2013 and June 2014. The isolated aerobic bacterial pathogens were identified on the basis of standard cultural characteristics and biochemical tests. Antibiotics resistance profiles of biofilm producing bacteria against selected antibiotics were then determined. Among the chronic wound infections, diabetic foot ulcers were most common 37 (37%), followed by surgical ulcers 27 (27%). Chronic wounds were common in male patients older than 40 years. Among the total 163 isolated bacterial pathogens the most prevalent bacterial species were Pseudomonas aeruginosa 44 (27%), Klebsiella pneumoniae 26 (16%), Staphylococcus species 22 (14%) and Streptococcus spp. 21 (13%). The isolation rate of bacterial pathogens was high among patients with diabetic foot ulcers 83 (50.9%). Among bacterial isolates, 108 (66.2%) were observed as biofilm producers while 55 (33.8%) did not form biofilm in our model. The investigated biofilm producing bacterial isolates showed comparatively high resistance against tested antibiotics compared to non-biofilm producing bacterial isolates. The most effective antibiotics were amikacine and cefepime against all isolates. Increased multidrug resistance in biofilm producing bacteria associated with chronic wounds was observed in this study. Judicious use of antibiotics is needed to control the wound associated biofilm associated pathogens.

The Toronto Symptom Assessment System for Wounds: a new clinical and research tool.

2009-10-01

To formulate a patient-rated assessment tool that facilitates the measurement of pain and polysymptom distress directly related to all classes of wounds. A prospective observational study derived from a sequential case series of patients with advanced illness was carried out to determine the most common symptoms associated with wounds from 9 distinct classes (malignant, pressure ulcers, iatrogenic, traumatic, diabetic foot ulcers, venous ulcers, arterial ulcers, infections/inflammatory lesions, and ostomies). Ten wound-related symptoms were identified and used to create a patient-scored assessment tool. The Toronto Symptom Assessment System for Wounds (TSAS-W) was then developed and used in a pilot trial during which patients completed TSAS-W at baseline and 7 days later. Five hundred thirty-one patients either presented with wounds at baseline or developed them during the 24-month follow-up period. Patients affected by any type of wound were asked to report on the top 3 symptoms directly attributable to their wounds. The pilot trial of TSAS-W involved 103 wounds afflicting 83 sequential patients. The most prevalent wound-related symptoms included pain, exudation, odor, itching, bleeding, aesthetic concern, swelling, and mass and bulk effects from the wound and associated dressings; 78.6% of the TSAS-W assessments were carried out by the patient alone, 14.6% were carried out by the patient assisted by a caregiver, and 6.8% were carried out entirely by a caregiver. The summation of all 10 TSAS-W parameters, the global wound symptom distress score (GWSDS), resulted in a mean for all wounds of 34.47 at baseline and decreased to a mean of 28.40 at 7 days later. Cosmetic or aesthetic concern and/or distress was associated with the highest mean scores of all symptoms. Malignant wounds and wounds involving the perineum and genitalia were associated with the highest GWSDSs. The TSAS-W is a new tool for systematically assessing the degree of pain and polysymptom distress associated with all classes of wounds. It is modeled after the Edmonton Symptom Assessment System that is widely used and validated in the palliative care arena. TSAS-W is composed of 10 symptom parameters that are individually assessed on 11-point numeric rating scales (0-10). The summation of all of the element symptom scores equates to a GWSDS. It may be used in the clinical setting to guide wound-related pain and polysymptom management. In addition, TSAS-W may be useful as a tool in facilitating clinical audit and future wound care research.

While the understanding of wound pathophysiology has progressed considerably over the past decades the improvements in clinical treatment has occurred to a minor degree. During the last years, however, new trends and initiatives have been launched, and we will continue to attain new information in the next decade. It is the hope that increasing parts of the new knowledge from basic wound healing research will be implemented in daily clinical practice. The development of new treatment products will also continue, and especially new technologies with combined types of dressing materials or dressing containing active substances will be accentuated. Further developments in the management structure and education will also continue and consensus of treatment guidelines, recommendations and organization models will hopefully be achieved.

Marjolin’s ulcer in chronic wounds – review of available literature

Bazaliński, Dariusz; Przybek-Mita, Joanna; Barańska, Beata

2017-01-01

Marjolin’s ulcer is a rare, aggressive skin cancer developing in scar tissue, chronic ulcers and areas affected by inflammations. Its incidence is estimated to range from 1% to 2% of all burn scars. It most frequently takes the form of squamous cell carcinoma which sometimes is diagnosed during examination of lesions developing in scars and hard-to-heal chronic wounds (pressure sores, leg ulcers). Therapeutic management of Marjolin’s ulcer requires well-designed treatment plan to ensure optimal medical care and good quality of life for the patient. The high risk of metastases and damage to the structure of vitally important organs determines the need for early diagnosis and prompt surgical intervention with supplementary therapy. The purpose of the study was to examine etiopathogenesis of Marjolin’s ulcer and principles of its treatment. The authors focused on the aspect of malignant degeneration in chronic wounds (leg ulcers, pressure sores) as a very rare, aggressive form of Marjolin’s ulcer. A review of the available literature on the issue of Marjolin ulcers was conducted using the key words; Marjolin ulcers, pressure sore, chronic wound. Malignant degeneration in chronic wounds is a very rare aggressive form of Marjolin ulcer. Increased oncological alertness should be displayed by nursing and medical personnel taking care of patients with chronic wounds. PMID:29180925

To describe the use of digital images captured by parents or guardians and sent to clinicians for assessment of wounds after pediatric ambulatory surgery. Subjects with digital images of post-operative wounds were identified as part of an on-going cohort study of infections after ambulatory surgery within a large pediatric healthcare system. We performed a structured review of the electronic health record (EHR) to determine how digital images were documented in the EHR and used in clinical care. We identified 166 patients whose parent or guardian reported sending a digital image of the wound to the clinician after surgery. A corresponding digital image was located in the EHR in only 121 of these encounters. A change in clinical management was documented in 20% of these encounters, including referral for in-person evaluation of the wound and antibiotic prescription. Clinical teams have developed ad hoc workflows to use digital images to evaluate post-operative pediatric surgical patients. Because the use of digital images to support follow-up care after ambulatory surgery is likely to increase, it is important that high-quality images are captured and documented appropriately in the EHR to ensure privacy, security, and a high-level of care.

Summary Objective To describe the use of digital images captured by parents or guardians and sent to clinicians for assessment of wounds after pediatric ambulatory surgery. Methods Subjects with digital images of post-operative wounds were identified as part of an ongoing cohort study of infections after ambulatory surgery within a large pediatric healthcare system. We performed a structured review of the electronic health record (EHR) to determine how digital images were documented in the EHR and used in clinical care. Results We identified 166 patients whose parent or guardian reported sending a digital image of the wound to the clinician after surgery. A corresponding digital image was located in the EHR in only 121 of these encounters. A change in clinical management was documented in 20% of these encounters, including referral for in-person evaluation of the wound and antibiotic prescription. Conclusion Clinical teams have developed ad hoc workflows to use digital images to evaluate post-operative pediatric surgical patients. Because the use of digital images to support follow-up care after ambulatory surgery is likely to increase, it is important that high-quality images are captured and documented appropriately in the EHR to ensure privacy, security, and a high-level of care.

Scar modification. Techniques for revision and camouflage.

The surgery and management of scars is a protracted and staged process that includes preparation of the skin through hygienic measures, scar softening (if indicated) with steroids, massage and pressure dressings, skilled execution of the surgical plan, and thorough postoperative wound care. This process generally covers a 1-year period for the various stages mentioned. Many general host and local skin factors will directly affect the final revision result. The two most important indirect factors that the surgeon must endeavor to control are optimal patient preparation and cutaneous health, and patient compliance with, and an ability to carry out, those wound care measures that the surgeon prescribes. Keloid and burn contracture scars represent two entities that are complicated and challenging to treat owing to their abnormal morphophysiologic features. Management of these scars is prolonged, and the patient must understand that the ultimate result will usually be a compromise. New grafting techniques, such as cultured autodermal grafts, offer improved initial management of burn wounds that may subsequently optimize scar revision in these patients. Keloids, and to a lesser extent hypertrophic scars, require steroid injections, pressure treatment, careful surgery, and protracted wound support and pressure treatment (exceeding 6 months) after surgery.

With the development of social economy, people's lifestyle has changed accompanied with the problem of population aging. The spectrum of disease also varied accordingly, thus led to complicated and varied wound aetiology, along with the formation of innumerably changed acute and chronic wounds. Therefore, it is hard to meet the requirement of multidisciplinary knowledge and technique in the diagnosis and treatment of some extraordinary agent wound with a single discipline. The extraordinary agent wound is caused by some uncommon or rare etiological factors, the specialty of which lays on the unique mechanism of wound formation, and a lot of disciplines were involved in the diagnosis and management of the wound. A unification of multiple disciplines is needed to integrate the relevant theory and technique to care the wound by giving consideration of the symptom and the aetiology. The primary diseases which induced the uncommon agent wound should be targeted and treated effectively; meanwhile, a comprehensive treatment combined with multiple new wound management techniques should be carried out to realize the objective of precise treatment.

Cutaneous wound healing is a complex multiple phase process, which overlaps each other, where several growth factors, cytokines, chemokines, and various cells interact in a well-orchestrated manner. However, an imbalance in any of these phases and factors may lead to disruption in harmony of normal wound healing process, resulting in transformation towards chronic nonhealing wounds and abnormal scar formation. Although various therapeutic interventions are available to treat chronic wounds, current wound-care has met with limited success. Progenitor stem cells possess potential therapeutic ability to overcome limitations of the present treatments as it offers accelerated wound repair with tissue regeneration. A substantial number of stem cell therapies for cutaneous wounds are currently under development as a result of encouraging preliminary findings in both preclinical and clinical studies. However, the mechanisms by which these stem cells contribute to the healing process have yet to be elucidated. In this review, we emphasize on the major treatment modalities currently available for the treatment of the wound, role of various interstitial stem cells and exogenous adult stem cells in cutaneous wound healing, and possible mechanisms involved in the healing process.

Wounds are the result of injuries to the skin that disrupt the other soft tissue. Healing of a wound is a complex and protracted process of tissue repair and remodeling in response to injury. Various plant products have been used in treatment of wounds over the years. Wound healing herbal extracts promote blood clotting, fight infection, and accelerate the healing of wounds. Phytoconstituents derived from plants need to be identified and screened for antimicrobial activity for management of wounds. The in vitro assays are useful, quick, and relatively inexpensive. Small animals provide a multitude of model choices for various human wound conditions. The study must be conducted after obtaining approval of the Ethics Committee and according to the guidelines for care and use of animals. The prepared formulations of herbal extract can be evaluated by various physicopharmaceutical parameters. The wound healing efficacies of various herbal extracts have been evaluated in excision, incision, dead space, and burn wound models. In vitro and in vivo assays are stepping stones to well-controlled clinical trials of herbal extracts. PMID:21716711

Angiogenic properties of dehydrated human amnion/chorion allografts: therapeutic potential for soft tissue repair and regeneration

PubMed Central

2014-01-01

Background Chronic wounds are associated with a number of deficiencies in critical wound healing processes, including growth factor signaling and neovascularization. Human-derived placental tissues are rich in regenerative cytokines and have been shown in randomized clinical trials to be effective for healing chronic wounds. In this study, PURION® Processed (MiMedx Group, Marietta, GA) dehydrated human amnion/chorion membrane tissue allografts (dHACM, EpiFix®, MiMedx) were evaluated for properties to support wound angiogenesis. Methods Angiogenic growth factors were identified in dHACM tissues using enzyme-linked immunosorbent assays (ELISAs), and the effects of dHACM extract on human microvascular endothelial cell (HMVEC) proliferation and production of angiogenic growth factors was determined in vitro. Chemotactic migration of human umbilical vein endothelial cells (HUVECs) toward pieces of dHACM tissue was determined using a standard in vitro transwell assay. Neovascularization of dHACM in vivo was determined utilizing a murine subcutaneous implant model. Results Quantifiable levels of the angiogenic cytokines angiogenin, angiopoietin-2 (ANG-2), epidermal growth factor (EGF), basic fibroblast growth factor (bFGF), heparin binding epidermal growth factor (HB-EGF), hepatocyte growth factor (HGF), platelet derived growth factor BB (PDGF-BB), placental growth factor (PlGF), and vascular endothelial growth factor (VEGF) were measured in dHACM. Soluble cues promoted HMVEC proliferation in vitro and increased endogenous production of over 30 angiogenic factors by HMVECs, including granulocyte macrophage colony-stimulating factor (GM-CSF), angiogenin, transforming growth factor β3 (TGF-β3), and HB-EGF. 6.0 mm disks of dHACM tissue were also found to recruit migration of HUVECs in vitro. Moreover, subcutaneous dHACM implants displayed a steady increase in microvessels over a period of 4 weeks, indicative of a dynamic intra-implant neovascular process. Conclusions Taken together, these results demonstrate that dHACM grafts: 1) contain angiogenic growth factors retaining biological activity; 2) promote amplification of angiogenic cues by inducing endothelial cell proliferation and migration and by upregulating production of endogenous angiogenic growth factors by endothelial cells; and 3) support the formation of blood vessels in vivo. dHACM grafts are a promising wound care therapy with the potential to promote revascularization and tissue healing within poorly vascularized, non-healing wounds.

Background Split-thickness autograft is the standard wound treatment for full-thickness burns. In large burns, sparse availability of uninjured skin prevents rapid closure of the wound, resulting in increased scar tissue formation or mortality. Tissue-engineered skin (ES) offers promise when autografts are not available. The Problem ES, constructed from a polymeric scaffold and skin cells, has been shown to reduce donor site area required to permanently close wounds, mortality, and morbidity from scarring but cannot restore all skin functions. Current generations of ES are orders of magnitude weaker than normal human skin, leading to difficulty in surgical application, greater susceptibility to mechanical damage during fabrication and application, and less elasticity and strength once engrafted. Basic/Clinical Science Advances Previous studies to improve ES biomechanics focus on altering the scaffolding material, which resulted in modest improvements but often inhibited proper skin development. As the skin is naturally under static strain, adding these mechanical cues to the culture environment is hypothesized to improve ES biomechanics. ES was cultured under applied static strains ranging from 0% to 40% strain for a total of 10 days. Strain magnitudes of 10% and 20% strain resulted in significantly stronger ES than unstrained controls, showed upregulation of many genes encoding structural extracellular matrix proteins, and exhibited increased epidermal cell proliferation and differentiation. Clinical Care Relevance Enhanced biomechanical properties of ES can allow for facile surgical application and less damage during dressing changes. Conclusion These findings suggest that mechanical cues play a significant role in skin development and should be further explored. PMID:24527283

Safety is a critically important factor in the selection of products used in neonatal and paediatric wound care. Given the lack of standardisation of neonatal and paediatric wound care protocols, the goal of this study was to present data on the safety and efficacy of active Leptospermum honey (ALH) in this patient population. A multicentre, retrospective chart review was conducted at eight inpatient facilities and one outpatient clinic between October 2011 and March 2014. The number of applications of ALH, adverse events, and the success of debridement and wound healing were recorded. Data were collected on 115 neonatal and paediatric patients, with 121 wounds requiring debridement, treated with ALH. Patients were treated for an average of 18.7 days. ALH was well tolerated, with two (1.7%) patients reporting adverse events involving a transient stinging sensation on application, which did not prohibit additional applications of ALH. Successful debridement was achieved in 86.0% (104 wounds), and 77.7% (94 wounds) were successfully closed using nonsurgical intervention. Outcomes in neonates were similar to the overall paediatric population, with 86.1% (31/36) wounds successfully debrided with no adverse events. In a subset of six patients with available pre- and post-treatment data, no clinically meaningful changes in white blood cell counts or glucose levels were associated with the initiation of treatment with ALH. The results of this study support ALH as a safe and effective treatment option in this group of patients. This study was supported by a grant from Derma Sciences (Princeton, NJ USA).

This paper is a report of a study to compare a medical grade honey with conventional treatments on the healing rates of wounds healing by secondary intention. There is an increasing body of evidence to support the use of honey to treat wounds, but there is a lack of robust randomized trials on which clinicians can base their clinical judgement. A sample of 105 patients were involved in a single centre, open-label randomized controlled trial in which patients received either a conventional wound dressing or honey. Data were collected between September 2004 and May 2007. The median time to healing in the honey group was 100 days compared with 140 days in the control group. The healing rate at 12 weeks was equal to 46.2% in the honey group compared with 34.0% in the conventional group, and the difference in the healing rates (95% confidence interval, CI) at 12 weeks between the two groups was 12.2% (-13.6%, 37.9%). The unadjusted hazard ratio (95% CI) from a Cox regression was equal to 1.30 (0.77, 2.19), P = 0.321. When the treatment effect was adjusted for confounding factors (sex, wound type, age and wound area at start of treatment), the hazard ratio increased to 1.51 but was again not statistically significant. Wound area at start of treatment and sex are both highly statistically significant predictors of time to healing. These results support the proposition that there are clinical benefits from using honey in wound care, but further research is needed.

The extremities are the most common anatomic location for gunshot wounds. Because of the prevalence of gunshot injuries, it is important that orthopaedic surgeons are knowledgeable about caring for them. The most common injuries seen with gunshot wounds are those of the soft tissues. Nonsurgical management of patients who have gunshot wounds with minimal soft-tissue disruption has been successfully accomplished in emergency departments for several years; this includes extremity wounds without nerve, intra-articular, or vascular injury. Stable, nonarticular fractures of an extremity have also been successfully treated with either minimal surgical or nonsurgical methods in the emergency department. Indications for surgical treatment include unstable fractures, intra-articular injuries, a significant soft-tissue injury (especially with skin loss), vascular injury, and/or a large or expanding hematoma.

Telemedical wound care is one of the applications of teledermatology. We present our experience using telemedicine in the successful assessment and treatment of three patients with hard-to-heal ulcers. Three patients were seen at the PEMEX General Hospital in Veracruz, Mexico. The first patient was a 53-year-old man with hypertension, morbid obesity, chronic venous insufficiency, recurrent erysipelas, leg ulcers and lymphoedema. There was one ulcer on his left lower leg (20 x 10 cm) and one on his right leg (9 x 7 cm). The second patient was a 73-year-old woman with class III obesity and ulcers in her right leg, secondary to surgical debridement of bullous erysipelas. The third patient was a 51-year-old female with rheumatoid arthritis with one ulcer on each leg and chronic lymphostasis. Photographs with a digital camera were taken and sent weekly via email to a wound care specialist in Mexico City. The photographs allowed the expert to diagnose and evaluate the chronic wounds periodically. In the present cases, telemedicine allowed us to have a rapid evaluation, diagnosis and treatment. The images were of enough quality to be useful and small enough to be sent via regular email to the remote physician who immediately gave his feedback. The expert was confident to give therapeutic recommendations in this way, and we considered this method to be very cost-effective, saving the patient and the health care system, especially in transportation.

Wound must be carefully treated to avoid serious infection that needs costly treatment. Method to enhance the recovery of the wound is crucial to have effective wound treatment. One of the technologies in wound treatment is transdermal patch that has the benefits of being non-invasive, easy to handle and permits constant drug dosage. In order to obtain a good controlled drug release, drug excipient needs to be investigated. Recently, natural Nanocrystal Cellulose (NCC) which can be synthesized from animal, algae, microorganism or plant has been actively used in drug delivery system as excipient. The application of NCC is advantageous due to its large surface area, biodegradable, non-toxic and abundance source.

Ulcers as a result of diabetes mellitus are a serious problem with an enormous impact on the overall global disease burden due to the increasing prevalence of diabetes. Because of long hospital stays, rehabilitation, often required home care and the use of social services diabetic foot complications are costly. Therapy with growth factors could be an effective and innovative add-on to standard wound care. What is the benefit of therapies with growth factors alone or in combination with other technologies in the treatment of diabetic foot ulcer assessed regarding medical, economical, social, ethical and juridical aspects? We systematically searched relevant databases limited to English and German language and publications since 1990. Cost values were adjusted to the price level of 2008 and converted into Euro. A review and an assessment of the quality of publications were conducted following approved methodical standards conforming to evidence-based medicine and health economics. We identified 25 studies (14 randomized controlled trials (RCT), nine cost-effectiveness analyses, two meta-analyses). The RCT compared an add-on therapy to standard wound care with standard wound care/placebo alone or extracellular wound matrix: in six studies becaplermin, in two rhEGF, in one bFGF, and in five studies the metabolically active skin grafts Dermagraft and Apligraf. The study duration ranged from twelve to 20 weeks and the study population included between 17 to 382 patients, average 130 patients. The treatment with becaplermin, rhEGF and skin implants Dermagraft and Apligraf showed in eight out of 13 studies an advantage concerning complete wound closure and the time to complete wound healing. Evidence for a benefit of treatment with bFGF could not be found. In four out of 14 studies the proportion of adverse events was 30% per study group with no difference between the treatment groups. The methodological quality of the studies was affected by significant deficiencies. The results showed becaplermin being cost-effective whereas no obvious statement can be made regarding Dermagraft and Apligraf because of diverging cost bases and incremental cost-effectiveness ratios. Differences in standard wound care are complicating the comparison of study results. Taking into consideration the small to very small sample sizes and other methodological flaws with high potential of bias, the validity of the results with regard to effectiveness and cost-effectiveness has to be considered limited. The duration of treatment and follow-up examinations is not long enough to assess the sustainability of the intervention and the surveillance of ulcer recurrences or treatment related adverse events like the development of malignancy. There are indications of an advantage for the add-on therapy with growth factors in diabetic foot ulcers concerning complete wound closure and the time to complete wound healing. Further more studies of high methodological quality with adequate sample sizes and sufficient follow-up periods are necessary also investigating patient-relevant parameters like the health-related quality of life, the acceptance and tolerance of the intervention in addition to clinical outcomes.
