Chronic wound is an important national healthcare problem, compounded by the fact that patients with chronic diseases such as diabetes are always vulnerable to develop chronic wounds. Wound care research has two strands: clinical and computational. On the clinical side, research has been focusing on how to effectively treat wounds. This includes measuring wounds, tracking their progression with time, and assessing their health. On the computational side, little has been done to treat a wound as an engineering system that needs to be modeled and analyzed with the ultimate goal of predicting the progress of wound healing and determining the factors that influence wound healing.

The Impact

Background Chronic wounds affect an estimated 2.21 per 1000 population. They are a significant source of morbidity and affect individuals physically, psychologically, socially and financially. Person-centered care is one approach to improve patient outcomes in wound care as it values patients' perspectives, beliefs and autonomy and considers the person as a whole within the cultural context in which care is provided. Aim We aimed to review the evidence on the use of person-centered care (PCC) in chronic wound care management and provide recommendations for practice and future research. Method Using a systematic review methodology, we searched six databases for full-text papers from 2009–2019 published in peer-reviewed journals with no limits on language. Results Eighteen articles on studies involving 3149 patients from nine countries were identified. Studies were conducted under three broad intervention categories: healthcare professional education (n=1); patient education (n=14) and telemedicine (n=3). Studies were equally focused on prevention and treatment of chronic wounds. Significant improvements were reported in patient knowledge, pain and self-care behaviours. Only two studies evaluated the impact on wound healing and one study estimated the cost of implementing person-centered care. Conclusions The evidence base to support PCC in wound management is developing and based on our review has shown improved outcomes in areas of pressure ulcer prevention, patient satisfaction, patient knowledge and quality of life, but clinical outcomes such as wound healing were less well explored. Further research with more objective outcome measures are required.

Abstract Background Chronic wounds constitute a significant medical and social problem. Chronic wound treatment may be supported by various techniques, such as negative pressure therapy, phototherapy or stem cells therapy, yet most of those supporting therapies need more evidence to be used for standard wound care. Current study covers the use of sonicated Antlerogenic Stem Cells (ASC) extract on chronic wounds. Methods Study was performed on 20 dermatological patients with venous leg ulcers, divided into two groups – treated with and without ASC extract respectively. The area and circumference of the wounds during the follow-up visits were measured on the wound imprint. Dynamics of wound healing was determined and compared between control and study group; statistics includes changes in absolute values (wound area, circumference), as well as relative (percentage of wound decrease, circumference/area ratio) and their change in time. For the purpose of Ki-67 immunohistochemical staining, sections were sampled from the wound edge at distinct check-points during therapy. Results of both groups were compared with Student test or Mann-Whitney test, depending on results distribution. Results Besides Ki-67 expression, all tested wound healing parameters (including relative and absolute wound decrease and changes in circumference/area ratio) were statistically significant more favorable in experimental group. Conclusion ASC extract significantly supported standard chronic wound treatment. Due to small population of study the results should be considered preliminary, yet promising for further research.

Giving a glance to the report of Wound Care Market by Product updated in 2017, we can see that wound care market is expected to reach USD 22.01 billion by 2022 from USD 18.35 billion at a CAGR of 3.7%. Numerous factors are driving the growth of this market, including the increasing prevalence of chronic wounds and acute wounds, increasing aged population, rising R&D activities and advancement in the field of wound care research. Advanced wound management products are accounted for the largest market share in 2017. These evidences mean that the wound care research represents a Clinical Emergency other than an interesting Marketing tool. Drug therapies so far fight efficaciously with the opportunistic pathologies derived from chronic wounds, although an unsolved challenge is still finding a useful remedy to correct the impaired wound healing process and overcome the chronic wound state, to avoid bacterial rising and severe pain. Traditional medicinal plants have been widely used in the management of wounds and different plant extracts have been evaluated for their wound healing properties through both in vitro and in vivo studies. Their phytochemical components in particular quercetin, contribute to their remedial properties in wound repair. Quercetin has important biological activities related to the improvement of the wound healing process. The present review discusses and focuses on the latest findings of the wound healing properties of quercetin, alone or as a part of plant extract, and its role as a new frontier in wound repair.

Background: A major global health issue is the existence of chronic wounds. Appropriate diagnosis and treatment is essential to promote wound healing and prevent further complications. Traditional methods for treatment and diagnosis of chronic wounds have shown to be of limited effectiveness. Therefore, there is a need for the development of diagnostic and therapeutic innovations in chronic wound care. Objective: This mini-review aims to provide insight in the current knowledge of the wound healing process and the deficiencies encountered in chronic wounds, which provides a basis for the development of innovations in chronic wound care. Furthermore, promising diagnostic and therapeutic innovations will be highlighted. Methods: Literature was searched for recent articles (=<10 years) describing the current knowledge about the wound healing process and chronic wounds. The most promising diagnostic and therapeutic innovations were gathered from articles published in the past 5 years. Results/Conclusion: Wound healing is a well-organized process consisting of four phases: coagulation, inflammation, proliferation and wound remodelling. Chronic wounds often stagnate in the inflammatory phase and/or experience an impaired proliferative phase. This mini-review has demonstrated that increased knowledge about the processes involved in wound healing has paved the way for the development of new diagnostic tools and treatments for chronic wounds. Increased knowledge about bacterial invasion and infection in has encouraged researchers to develop diagnostic tools to help clinicians detect these phenomena appropriately and in time. Other researchers have shown that they are able to design/extract biochemical compounds that intervene in the disrupted healing processes in chronic wounds.

Wound Healing Process

Chronic wounds represent an economic burden to healthcare systems worldwide and a societal burden to patients, deeply impacting their quality of life. The incidence of recalcitrant wounds has been steadily increasing since the population more susceptible, the elderly and diabetic, are rapidly growing. Chronic wounds are characterised by a delayed wound healing process that takes longer to heal under standard of care than acute (i.e. healthy) wounds. Two of the most common problems associated with chronic wounds are inflammation and infection, with the latter usually exacerbating the former. With this in mind, researchers and wound care companies have developed and marketed a wide variety of wound dressings presenting different compositions but all aimed at promoting healing. This makes it harder for physicians to choose the correct therapy, especially given a lack of public quantitative data to support the manufacturers’ claims. This review aims at giving a brief introduction to the clinical need for chronic wound dressings, focusing on inflammation and evaluating how bio-derived and synthetic dressings may control excess inflammation and promote healing.

Objective — To explore the application value of observation of moist wound theory in chronic wound care. Methods — From February 2019 to May 2020, a total of 96 patients with chronic wounds were treated in this hospital. The patients were divided into two groups based on the two-color ball method, with 48 cases in each group. Routine wound nursing (48 patients, the control group) and moist wound theory (48 patients, the experimental group) were used to compare the wound healing between the two groups. Results — The wound healing rate of 48 patients in the experimental group was significantly higher than that in the control group, and there was a significant difference (P<0.05). The incidence of chronic wound complications (wound pain, wound infection, tissue adhesion) of 48 patients in the experimental group was significantly lower than that in the control group, and there was a significant difference (P<0.05). Conclusion — The application of moist wound theory in chronic wound nursing can promote the rehabilitation of patients with chronic wounds, improve the rate of wound healing, reduce the incidence of complications, and improve the patients' nursing efficacy.

Viable Approach

: Chronic wounds remain a significant public problem and the development of wound treatments has been a research focus for the past few decades. Despite advances in the products derived from endogenous substances involved in a wound healing process (e.g. growth factors, stem cells, and extracellular matrix), effective and safe wound therapeutics are still limited. There is an unmet need to develop new therapeutics. Various new pathways and targets have been identified and could become a molecular target in designing novel wound agents. Importantly, many existing drugs that target these newly identified pathways could be repositioned for wound therapy, which will facilitate fast translation of research findings to clinical applications. This review discusses the newly identified pathways/targets and their potential uses in the development of wound therapeutics. Some herbs and amphibian skins have been traditionally used for wound repairs and their active ingredients have been found to act in these new pathways. Hence, screening these natural products for novel wound therapeutics remains a viable approach. The outcomes of wound care using natural wound therapeutics could be improved if we can better understand their cellular and molecular mechanisms and fabricate them in appropriate formulations, such as using novel wound dressings and nano-engineered materials. Therefore, we also provide an update on the advances in the wound therapeutics from natural sources. Overall, this review offers new insights into novel wound therapeutics.

Recent SARS-CoV-2 pandemic leading to a rapidly increasing number of hospitalizations enforced reevaluation of wound management strategies. The optimal treatment strategy for patients with chronic wounds and those recovering from emergency and urgent oncological surgery should aim to minimize the number of hospital admissions, as well as the number of surgical procedures and decrease the length of stay to disburden the hospital staff and to minimize viral infection risk. One of the potential solutions that could help to achieve these goals may be the extensive and early use of NPWT devices in the prevention of wound healing complications. Single-use NPWT devices are helpful in outpatient wound treatment and SSI prevention (ciNPWT) allowing to minimize in-person visits to the health care center while still providing the best possible wound-care. Stationary NPWT should be used in deep SSI and perioperative wound healing disorders as soon as possible. Patient’s education and telemedical support with visual wound healing monitoring and video conversations have the potential to minimize the number of unnecessary in-person visits in patients with wounds and therefore substantially increase the level of care.
