Thomas K. Hunt is a general surgeon. Through his basic wound healing research and clinical work with wound patients he has been a great inspiration for my work in wound healing. In order to fulfill Dr. Hunt's vision, the clinical wound healing arena must be organized in an optimal way, and this article focuses on different options. Multidisciplinary wound care teams or centers focusing on all types of problem wounds have proved to be most effective at providing treatment and care for patients with problem wounds. The ultimate model is an outpatient clinic and an inpatient ward joined within a departmental structure, which represents an integrated part of an accepted national expert program on wound healing. Different types of center models can be established with different advantages and disadvantages. Currently, the wound care arena is being organized in Denmark and the model is described in this article. Of all specialties involved in treatment of wounds, surgery is of vital importance. "Wound healing is the keystone on which surgery is founded" (Thomas K. Hunt). This has long been understood in relation to acute wounds, while the importance of surgery in the treatment of chronic wounds has been less widely recognized. Surgical procedures directly related to the wound consist of debridement of all types of problem wounds and, in more specialized procedures such as skin transplantation, different types of flap constructions, bone surgery, and tendo-Achilles lengthening. Arterial reconstruction is a type of surgery that indirectly, through improved tissue perfusion, improves healing of problem wounds. This study concludes that multidisciplinary specialized wound healing concepts integrated into the national health care system as accepted expert functions would be the ideal way to organize wound healing to best benefit patients and society. Emphasis is on the importance of surgical procedures in wound healing and care. The models described can be applied with minor adjustments to both industrialized and developing countries.  相似文献

Considerable developments have occurred in wound healing and care over the last few decades. Innovative technologies such as use of growth factors, bioengineered skin, topical negative pressure, heat, oxygen, and others have entered the clinic. These techniques have been advantageous, but even the most advanced and sophisticated product requires proper wound care and wound bed preparation in order to function optimally. It has been shown that the organization of a wound team, not the change in products, increases the healing of problem wounds (MTV Report, Denmark, 2003). Efficacy studies are generally performed in a few centers with investigators already experienced in the field. This probably leads to an optimal efficacy of the product. Problems arise when the product is marketed and is used by clinicians not specially educated in wound care. If no treatment plan and education is performed, product efficacy and cost‐effectiveness decrease dramatically. This is clearly a major problem for patients, but also for communities and, in the end, for companies' sale of the product. Structuring of treatment and education is for these reasons the largest present challenge in the area of wound healing. The optimal way to treat nonhealing wounds is based on a multidisciplinary concept that has been implemented in a national health care system as a recognized expert function. It should consist of a specific treatment plan including modern wound care products and well‐educated personnel. This structure is similar to other areas of the medical profession, but has to a lesser degree been established in the treatment of problem wounds. A growing understanding of the importance of this area is, however, shown by the increasing number of working groups focusing on organization and education in wound care. Presently the European Wound Management Association, the World Union of Wound Healing Societies, and The Danish Wound Healing Society have created such types of working groups.  相似文献

Hyaluronate-iodine complex is a wound healing adjuvant approved for use in the European Union. The objective of this study is to validate hyaluronate-iodine as a potential wound healing agent. Patients were recruited from the hospital, the outpatient clinic, and the wound healing center. Hyaluronate-iodine soaked gauze was applied to wounds either daily or every other day depending on the amount of wound exudate. Wounds were measured weekly, and progression was documented with digital photography. All wounds were debrided as needed using standard surgical techniques. Fourteen patients (19 wounds) were entered into this prospective study, and 10 patients completed treatment. Fourteen wounds progressed to complete healing with a mean healing time of 18.1 ± 15.1 weeks. Treatment was interrupted in four patients. One patient discontinued treatment due to pain related to application of hyaluronate-iodine, another patient for transportation issues, and the other two patients were lost to follow-up due to relocation out of state and noncompliance with scheduled appointments. Hyaluronate-iodine was helpful in the healing of all types of wounds treated in this pilot study. The antiadhesive and antimicrobial properties of hyaluronate-iodine create a desirable environment conducive to wound healing without apparent detrimental effects.  相似文献

HYPOTHESIS: In patients with diabetic foot and pressure ulcers, early intervention with biological therapy will either halt progression or result in rapid healing of these chronic wounds. DESIGN: In a prospective nonrandomized case series, 23 consecutive patients were treated with human skin equivalent (HSE) after excisional debridement of their wounds. SETTING: A single university teaching hospital and tertiary care center. PATIENTS AND METHODS: Twenty-three consecutive patients with a total of 41 wounds (1.0-7.5 cm in diameter) were treated with placement of HSE after sharp excisional debridement. All patients with pressure ulcers received alternating air therapy with zero-pressure alternating air mattresses. MAIN OUTCOME MEASURE: Time to 100% healing, as defined by full epithelialization of the wound and by no drainage from the site. RESULTS: Seven of 10 patients with diabetic foot ulcers had complete healing of all wounds. In these patients 17 of 20 wounds healed in an average of 42 days. Seven of 13 patients with pressure ulcers had complete healing of all wounds. In patients with pressure ulcers, 13 of 21 wounds healed in an average of 29 days. All wounds that did not heal in this series occurred in patients who had an additional stage IV ulcer or a wound with exposed bone. Twenty-nine of 30 wounds that healed did so after a single application of the HSE. CONCLUSIONS: In diabetic ulcers and pressure ulcers of various durations, the application of HSE with the surgical principles used in a traditional skin graft is successful in producing healing. The high success rate with complete closure in these various types of wounds suggests that HSE may function as a reservoir of growth factors that also stimulate wound contraction and epithelialization. If a wound has not fully healed after 6 weeks, a second application of HSE should be used. If the wound is not healing, an occult infection is the likely cause. All nonischemic diabetic foot and pressure ulcers that are identified and treated early with aggressive therapy (including antibiotics, off-loading of pressure, and biological therapy) will not progress.  相似文献

PURPOSE: The purpose of this study was to examine nurses' ratings of appropriateness of wound treatments and wound healing for patients in home care in relation to patient demographic and visit variables. DESIGN: A cross-sectional design was used. SETTING AND SUBJECTS: Data were collected about patients with wounds by 281 nurses from 13 home care agencies located throughout lower Michigan. Patients with wounds (n = 881) ranged in age from 21 to 100 years. They included 492 women and 383 men who were white (72.4%) or African-American (26%). INSTRUMENTS: The Community Wound Assessment Tool was developed for the study and was used to obtain demographic and wound data. The demographic section contained information about the patient's age, sex, reason for the visit, length of visit, and time the case was opened. The wound section included the wound type, treatments, presence of incontinence, nutritional supplementation, and adverse home environmental factors. Nurses rated wounds as healing or not healing. Wound treatments were rated as all appropriate, some appropriate/inappropriate, and all inappropriate. METHODS: Nurses were systematically selected from each agency and collected data about each patient visited on one occasion. MAIN OUTCOME MEASUREMENTS The main outcome measurements were the relationship of patient demographic variables and visit variables to the appropriateness of wound treatments and wound healing. RESULTS: The nurses' rating of wound treatments as appropriate was significantly related to younger patient age and a shorter time for the case to be open. Wound healing was initially associated with younger patient age, continence of urine or stool, shorter home visits, shorter time for the case to be open, and fewer reasons for the visit. When wound healing was controlled for the type of wound in path analysis, the patient's age was no longer significant and incontinence appeared to impair healing of nonsurgical wounds. The appropriateness of the wound treatments was significantly related to wound healing. CONCLUSIONS: Nurses' ratings of appropriateness of wound treatments and healing are significantly related to factors that affect length of service and complexity of care for the home care patient with a wound. Decisions nurses make about wound treatments and healing are important for the patient as well as for the agency.  相似文献

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.  相似文献

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.  相似文献

In times of increasing economical pressure on the health care systems, it is important to optimise the outpatient treatment of chronic wounds. Another aim of wound healing research is to discover agents to accelerate healing. Wound healing trajectories or healing velocities can provide information to demonstrate the endpoints for wound healing. A great problem in clinical trials is to specify these parameters. Therefore, we developed a mathematical model for more transparency. In this initial project, we observed 19 wounds to construct the wound healing trajectories after transplantation of autologous keratinocytes, and the results are so encouraging that investigation in this area will continue. The developed mathematical model describes the clinical observed healing process. It was possible to find parameters to distinguish between old and young patients, retrospectively or prospectively calculate the healing rates and to determine exactly the endpoint of healing. Therefore, our model might be very useful in practices or for studies.  相似文献

Pressure injuries affect 1 to 46% of residents in aged care (long term) facilities and cause a substantial economic burden on health care systems. Remote expert wound nurse consultation has the potential to improve pressure injury outcomes; however, the clinical and cost effectiveness of this intervention for healing of pressure injuries in residential aged care require further investigation. We describe the remote expert wound nurse consultation intervention and the method of a prospective, pilot, cluster randomised controlled trial. The primary outcome is number of wounds healed. Secondary outcomes are wound healing rate, time to healing, wound infection, satisfaction, quality of life, cost of treatment and care, hospitalisations, and deaths. Intervention group participants receive the intervention over a 12-week period and all participants are monitored for 24 weeks. A wound imaging and measurement system is used to analyse pressure injury images. A feasibility and fidelity evaluation will be concurrently conducted. The results of the trial will inform the merit of and justification for a future definitive trial to evaluate the clinical and cost effectiveness of remote expert wound nurse consultation for the healing of pressure injuries in residential aged care.  相似文献

Wounds that exhibit delayed healing add extraordinary clinical, economic, and personal burdens to patients, as well as to increasing financial costs to health systems. New interventions designed to ease such burdens for patients with cancer, renal, or ophthalmologic conditions are often cleared for approval by the U.S. Food and Drug Administration (FDA) using multiple endpoints but the requirement of complete healing as a primary endpoint for wound products impedes FDA clearance of interventions that can provide other clinical or patient‐centered benefits for persons with wounds. A multidisciplinary group of wound experts undertook an initiative, in collaboration with the FDA, to identify and content validate supporting FDA criteria for qualifying wound endpoints relevant to clinical practice (CP) and patient‐centered outcomes (PCO) as primary outcomes in clinical trials. As part of the initiative, a research study was conducted involving 628 multidisciplinary expert wound clinicians and researchers from 4 different groups: the interdisciplinary core advisory team; attendees of the Spring 2015 Symposium on Advanced Wound Care (SAWC); clinicians employed by a national network of specialty clinics focused on comprehensive wound care; and Association for the Advancement of Wound Care (AAWC) and Wound Healing Society (WHS) members who had not previously completed the survey. The online survey assessed 28 literature‐based wound care endpoints for their relevance and importance to clinical practice and clinical research. Fifteen of the endpoints were evaluated for their relevance to improving quality of life. Twenty‐two endpoints had content validity indexes (CVI) ≥ 0.75, and 15 were selected as meriting potential inclusion as additional endpoints for FDA approval of future wound care interventions. This study represents an important first step in identifying and validating new measurable wound care endpoints for clinical research and practice and for regulatory evaluation.  相似文献

The advancing technologies available to the orthopedist are a necessary adjunct to heal wounds about the foot and ankle successfully. Successful wound healing should be viewed as a multidisciplinary approach, using the strengths of each discipline. Critical to an integrated method is communication preoperatively between the orthopedist and the plastic surgeon to create a streamlined process. This leads not only to improved rates of wound healing, but also to improved functional outcomes while reducing risks for recurrence.  相似文献

Multidisciplinary wound care centers have proliferated as a result of an increasing need for care of nonhealing wounds. Information regarding types of wounds treated, length of treatment, compliance with treatment, and rates of healing was collected from a tertiary care hospital-based wound center over a 7-year period. Venous stasis ulcers were the most common type of wound treated (21%) and were also the most likely to heal. Pressure ulcers (20%), diabetic neuropathic ulcers (14%), ischemic ulcers (6%), and postsurgical wounds (6%) comprised the remainder of wounds treated. The success of treating wounds varied greatly with the wound's etiology. Despite the chronic nature of these wounds, most patients did not become long-term patients of the wound center. This study provides baseline outcome measures, which can serve as the basis for the comparison of treatment protocols and the development of prospective clinical trials.  相似文献

BACKGROUND: Immediate reconstruction is the preferred approach to the management of defects following Mohs micrographic surgery. In a minority of patients, however, reconstruction is contraindicated, and a long-term biological dressing that stimulates wound healing and minimizes wound care is desirable. OBJECTIVE: We wanted to assess the utility of a lyophilized, type I bovine collagen matrix (SkinTemp) in wound care and wound healing following Mohs micrographic surgery. METHODS: Fifteen patients were treated with a bovine collagen matrix following Mohs micrographic surgery. Study wounds were evaluated for time to complete granulation, time to complete epithelialization, and adverse reactions including infection and allergy. The time to complete healing (granulation and epithelialization) for this group was compared to 15 size- and site-matched surgical defects. RESULTS: The use of bovine collagen matrix provided more rapid wound healing than traditional second intention healing at all anatomic sites studied. The time to complete healing averaged 6.1 weeks with bovine collagen matrix versus 9.4 weeks for the control group. Use of bovine collagen matrix required an average of 3.0 dressing changes weekly compared to 7.0 changes weekly in the control group. There were no wound infections or allergic reactions to it. CONCLUSIONS: A Type I bovine collagen matrix provided a safe, readily available alternative to traditional methods of second intention healing. It minimized wound care while reducing the time for complete healing. A larger study should be performed to confirm the results of this pilot study.  相似文献

Non-healing wounds are a major threat to public health throughout the United States. Tissue healing is complex multifactorial process that requires synchronicity of several cell types. Endolysosomal trafficking, which contributes to various cell functions from protein degradation to plasma membrane repair, is an understudied process in the context of wound healing. The lysosomal trafficking regulator protein (LYST) is an essential protein of the endolysosomal system through an indeterminate mechanism. In this study, we examine the impact of impaired LYST function both in vitro with primary LYST mutant fibroblasts as well as in vivo with an excisional wound model. The wound model shows that LYST mutant mice have impaired wound healing in the form of delayed epithelialization and collagen deposition, independent of macrophage infiltration and polarisation. We show that LYST mutation confers a deficit in MCP-1, IGF-1, and IGFBP-2 secretion in beige fibroblasts, which are critical factors in normal wound healing. Identifying the mechanism of LYST function is important for understanding normal wound biology, which may facilitate the development of strategies to address problem wound healing.  相似文献

伤口治疗中心建立与烧伤整形学科发展   总被引:1,自引:1,他引:1  
To study the interaction between establishment of wound care center and development of discipline of burns and plastic surgery. The changes in number of outpatient,time for dressing change per patient, outpatient service income,number of inpatients and operations in our hospital were summarized and retrospectively analyzed before and after establishment of wound care center. The proportion of patients with chronic wounds and skin and soft tissue defects after trauma among all inpatients in the same term were investigated. Meanwhile, the development of discipline of burns and plastic surgery before and after establishment of wound care center was analyzed. Compared with those in the year before establishment of wound care center, outpatient number, time for dressing change per patient,outpatient service income, inpatient number, and amount of operations were all increased(with increase rate of 330% , 569%,325%, 161% , and 173%, respectively) in the year after establishment of wound care center. The ratio of patients with chronic wounds and skin and soft tissue defects after trauma among all inpatients was respectively increased from 4.3% and 4.5% in the year before establishment of wound care center to 9.2% and 12.4% in the year after establishment of wound care center. Patient satisfaction, bed utilization rate, levels of wound treatment and repair were all improved after establishment of wound care center. So we come to conclusions as follows. Establishment of wound care center can promote development of the standard of burns and plastic surgery. Comprehensive use of multidisciplinary theories and techniques concerning burns, plastic and aesthetic surgery, medical aesthetics, etc. can be beneficial for improvement of quality of wound healing and achievement of cosmetic effect, and wound care center may be further developed.  相似文献

Problem wounds, which fail to respond to traditional medical and surgical therapy, can be challenging to the plastic surgeon. Surgical, outpatient, and inpatient wound care costs can be exorbitant. Indirect costs, such as those related to patient productivity, disability, and premature death, can also be significant. The underlying problem in failure of a wound to heal is usually hypoxia and infection. HBO treatments in selected patients can facilitate healing by increasing tissue oxygen tension, thus providing the wound with a more favorable environment for repair. Therefore, HBO therapy can be an important component to any comprehensive wound care program.  相似文献

Chronic wounds adversely affect patient quality of life, increase the risk of mortality, and impose high costs on healthcare systems. Since protein-energy malnutrition or specific nutrient deficiencies can delay wound healing, nutritionally focused care is a key strategy to help prevent or treat the occurrence of non-healing wounds. The objective of our study of inpatients in a rehabilitation hospital was to quantify the effect of daily wound-specific oral nutritional supplementation (WS-ONS) on healing chronic wounds. Using electronic medical records, we conducted a retrospective analysis of patients with chronic wounds. We identified records for (a) a treatment group who received standard wound care + usual hospital diet + daily WS-ONS for ≥14 days, and (b) a control group who received standard wound care + a usual hospital diet. We collected data for demographics, nutritional status, and wound-relevant health characteristics. We examined weekly measurements of wound number and sizes (surface area for superficial wounds or volume for non-superficial wounds). There were 341 patients identified, 114 with 322 wounds in the treatment group and 227 patients with 420 wounds in the control group. We found that rehabilitation inpatients who were given nutritional support had larger wounds and lower functional independence on admission. At discharge, wound area reduction (percent) was nearly two-fold better in patients who were given daily WS-ONS + usual hospital diet compared to those who consumed usual diet only (61.1% vs 34.5%). Overall, weekly wound improvement (lowered wound area or wound volume) was more likely in the WS-ONS group than in the Control group, particularly from the start of care to week 2. Inpatients with largest wounds and lowest functional independence on admission were most likely to be given WS-ONS, an indication that caregivers recognised the need for supplementation. Week-to-week improvement in wound size was more likely in patients who received WS-ONS than in those who did not. Specifically, wound areas and wound volumes were significantly lower at discharge among patients who were given specialised nutritional support. More research in this field is needed to improve care and reduce healthcare costs.  相似文献

Bacterial biofilm has been shown to play a role in delaying wound healing of chronic wounds, a major medical problem that results in significant health care burden. A reproducible animal model could be very valuable for studying the mechanism and management of chronic wounds. Our previous work showed that Pseudomonas aeruginosa (PAO1) biofilm challenge on wounds in diabetic (db/db) mice significantly delayed wound healing. In this wound time course study, we further characterize the bacterial burden, delayed wound healing, and certain aspects of the host inflammatory response in the PAO1 biofilm‐challenged db/db mouse model. PAO1 biofilms were transferred onto 2‐day‐old wounds created on the dorsal surface of db/db mice. Control wounds without biofilm challenge healed by 4 weeks, consistent with previous studies; none of the biofilm‐challenged wounds healed by 4 weeks. Of the biofilm‐challenged wounds, 64% healed by 6 weeks, and all of the biofilm‐challenged wounds healed by 8 weeks. During the wound‐healing process, P. aeruginosa was gradually cleared from the wounds while the presence of Staphylococcus aureus (part of the normal mouse skin flora) increased. Scabs from all unhealed wounds contained 107 P. aeruginosa, which was 100‐fold higher than the counts isolated from wound beds (i.e., 99% of the P. aeruginosa was in the scab). Histology and genetic analysis showed proliferative epidermis, deficient vascularization, and increased inflammatory cytokines. Hypoxia inducible factor expression increased threefold in 4‐week wounds. In summary, our study shows that biofilm‐challenged wounds typically heal in approximately 6 weeks, at least 2 weeks longer than nonbiofilm‐challenged normal wounds. These data suggest that this delayed wound healing model enables the in vivo study of bacterial biofilm responses to host defenses and the effects of biofilms on host wound healing pathways. It may also be used to test antibiofilm strategies for treating chronic wounds.  相似文献

The care principles of injuries base on founded knowledge about the phases of wound healing, the causes of wound healing disturbances and the development of wound infections. The wound care includes the judgement of injuries, the surgical wound treatment and the aftercare. The wound evaluation with four categories makes a different therapeutic approach possible. The primary union is aspired to all non-infected wounds by direct wound closure. Suspicious infected and infected wounds are treated open after adequate wound excision. A secondary suture with a delayed primary wound closure is possible when the inflammation symptoms are recurrent. Other important aspects of wound care are a correct wound dressing, wound control and the checking for tetanus prophylaxis.  相似文献

BACKGROUND: MHC-class-II-deficient mice lack T helper cell dependent immune reactions. T cell related immune functions are critical for normal wound healing. We hypothesized that MHC-II-deficiency compromises wound repair by affecting the normal wound immune response. MATERIAL AND METHODS: Groups of 10 male MHC-class II-knockout mice and wild-type controls underwent dorsal skin incision. Polyvinyl alcohol sponges were then inserted subcutaneously. The mice were sacrificed 10 days later to determine wound breaking strength and reparative collagen deposition. Activity of T cells and macrophages isolated from the spleens and from the healing wounds was investigated. Fibroblasts derived from the wounds were tested ex vivo for proliferative activity and collagen synthesis. RESULTS: Wound collagen deposition and wound breaking strength were impaired in MHC-class-II-knockout mice (P < 0.05). Impaired healing was reflected in diminished mitogen-reactivity of splenic T-cells (P < 0.01), and decreased CD4 expression in wounds. In addition, basal and LPS + IFN-gamma-induced synthesis of TNF-alpha and nitric oxide by wound-derived macrophages was impaired. Exvivo, fibroblast proliferation and fibroblast collagen production from MHC-II-deficient mice was decreased. CONCLUSION: MHC-II-deficiency compromises wound healing. This may be a reflection of impaired wound immune cell function and decreased activity of wound fibroblasts.  相似文献
