Consensus guidance for the use of debridement techniques in the UK

Gray, D., Acton, C., Chadwick, P., Fumarola, S., Leaper, D.J., Morris, C., Stang, D., Vowden, Kath, Vowden, Peter, Young, T. 01 March 2011 (has links)
No / In Autumn 2010, a multidisciplinary group of clinicians met in Manchester to discuss the issue of debridement in wound management. There are various debridement techniques available in the UK, but facilities and skills vary. This paper, resulting from the meeting, briefly outlines the differing techniques used, the levels of skill required to use them and the wound types for which they are appropriate. It is important that clinicians practising debridement are aware of the variations in method, and the limitations of their own skills and competency so that, if appropriate, the patient can be referred to receive timely and appropriate intervention.

Appropriate use of topical haemoglobin in chronic wound management: consensus opinions

Chadwick, P., McCardle, J., Mohamud, L., Tickle, J., Vowden, Kath, Vowden, Peter January 2015 (has links)
No / Oxygen has a crucial role in wound healing; 97% of chronic, non-healing wounds have been shown to have low oxygen levels (Hauser, 1987). Topical oxygen therapy has been shown to be effective in treating non-healing wounds, but is still underutilised. A working group of key opinion leaders met in February 2015 to determine the potential role of topical haemoglobin in non-healing wounds and to develop a clear decision-making pathway for clinical practice, as well as sharing practical tips for use. The group’s consensus recommendations on appropriate use are presented here.

New techniques for wound debridement

Madhok, B.M., Vowden, Kath, Vowden, Peter January 2013 (has links)
No / No / Debridement is a crucial component of wound management. Traditionally, several types of wound debridement techniques have been used in clinical practice such as autolytic, enzymatic, biodebridement, mechanical, conservative sharp and surgical. Various factors determine the method of choice for debridement for a particular wound such as suitability to the patient, the type of wound, its anatomical location and the extent of debridement required. Recently developed products are beginning to challenge traditional techniques that are currently used in wound bed preparation. The purpose of this review was to critically evaluate the current evidence behind the use of these newer techniques in clinical practice. There is some evidence to suggest that low frequency ultrasound therapy may improve healing rates in patients with venous ulcers and diabetic foot ulcers. Hydrosurgery debridement is quick and precise, but the current evidence is limited and further studies are underway. Debridement using a monofilament polyester fibre pad and plasma-mediated bipolar radiofrequency ablation are both very new techniques. The initial evidence is limited, and further studies are warranted to confirm their role in management of chronic wounds.

Healing chronic wounds: the potential use of hypothermic processing of amniotic tissue to treat chronic wounds

Kasparian, Amy 12 July 2018 (has links)
Chronic diabetic foot ulcers, venous leg ulcers and pressure ulcers affect a large subset of the United State population yet they remain a challenge for physicians to treat. There are many different types of products on the market for the treatment of chronic wounds. Some use living cells but only two are FDA approved to heal chronic wounds. A new type of product recently garnered attention in the wound care market because it also contains living cells: hypothermically stored amniotic tissue products. Hypothermically stored amniotic tissue is unique because it maintains living cells and offers the benefits of containing signaling molecules and maintaining an intact extra cellular matrix. While there are other types of amniotic or placental tissue products in the wound care market, they are processed by dehydration or cryopreservation which limits their capacities for maintaining living cells. This thesis will explore the potential for hypothermically processed amniotic tissue products to treat chronic wounds.

Validating a Home Health Care Staff Educational Module for Wound Treatment and Documentation

Hebert, Kimberly Sanders 01 January 2018 (has links)
Although guidelines and minimal standards for the care and documentation of wounds in home health care settings in the United States are available, there is a lack of compliance among many home health care agencies (HHAs) with regard to the accuracy of wound documentation and care of wounds. Failure to follow guidelines for wound care according to Centers for Medicare and Medicaid Services and Home Health Outcome and Assessment Information System standards could result in loss of revenue for HHAs, improper treatment of wounds, and legal ramifications. The purpose of this doctoral project was to develop and validate a staff educational module on wounds and wound documentation for an HHA. Benner's from-novice-to-expert model was the conceptual framework for understanding nurses' matriculation. The practice-focused question focused on whether a wound staff educational module increased the home health care nurse's knowledge about wounds and wound documentation. A 5-level Likert scale was used by an expert panel to validate the staff educational module. Descriptive analysis was used to evaluate the data. The results of the survey supported implementing the educational module with recommendations (overall percentage 93% [4.4]). The findings of this project contribute to social change by increasing nurses' knowledge of wound care, improving the quality of wound care, increasing reimbursement and revenue, and decreasing the cost of care for wounds.

Health economic burden that wounds impose on the National Health Service in the UK

Guest, J.F., Ayoub, N., McIlwraith, T., Uchegbu, I., Gerrish, A., Weidlich, D., Vowden, Kath, Vowden, Peter 20 October 2015 (has links)
Yes / To estimate the prevalence of wounds managed by the UK's National Health Service (NHS) in 2012/2013 and the annual levels of healthcare resource use attributable to their management and corresponding costs. METHODS: This was a retrospective cohort analysis of the records of patients in The Health Improvement Network (THIN) Database. Records of 1000 adult patients who had a wound in 2012/2013 (cases) were randomly selected and matched with 1000 patients with no history of a wound (controls). Patients' characteristics, wound-related health outcomes and all healthcare resource use were quantified and the total NHS cost of patient management was estimated at 2013/2014 prices. RESULTS: Patients' mean age was 69.0 years and 45% were male. 76% of patients presented with a new wound in the study year and 61% of wounds healed during the study year. Nutritional deficiency (OR 0.53; p<0.001) and diabetes (OR 0.65; p<0.001) were independent risk factors for non-healing. There were an estimated 2.2 million wounds managed by the NHS in 2012/2013. Annual levels of resource use attributable to managing these wounds and associated comorbidities included 18.6 million practice nurse visits, 10.9 million community nurse visits, 7.7 million GP visits and 3.4 million hospital outpatient visits. The annual NHS cost of managing these wounds and associated comorbidities was pound5.3 billion. This was reduced to between pound5.1 and pound4.5 billion after adjusting for comorbidities. CONCLUSIONS: Real world evidence highlights wound management is predominantly a nurse-led discipline. Approximately 30% of wounds lacked a differential diagnosis, indicative of practical difficulties experienced by non-specialist clinicians. Wounds impose a substantial health economic burden on the UK's NHS, comparable to that of managing obesity ( pound5.0 billion). Clinical and economic benefits could accrue from improved systems of care and an increased awareness of the impact that wounds impose on patients and the NHS.

Oestrogen promotes healing in a bacterial LPS model of delayed cutaneous wound repair

Crompton, R., Williams, H., Ansell, David, Campbell, Laura, Holden, K., Cruickshank, S., Hardman, M.J. 06 May 2020 (has links)
No / Wound infection is a major clinical problem, yet understanding of bacterial host interactions in the skin remains limited. Microbe-derived molecules, known as pathogen-associated molecular patterns, are recognised in barrier tissues by pattern-recognition receptors. In particular, the pathogen-associated molecular pattern, lipopolysaccharide (LPS), a component of microbial cell walls and a specific ligand for Toll-like receptor 4, has been widely used to mimic systemic and local infection across a range of tissues. Here we administered LPS derived from Klebsiella pneumoniae, a species of bacteria that is emerging as a wound-associated pathogen, to full-thickness cutaneous wounds in C57/BL6 mice. Early in healing, LPS-treated wounds displayed increased local apoptosis and reduced proliferation. Subsequent healing progression was delayed with reduced re-epithelialisation, increased proliferation, a heightened inflammatory response and perturbed wound matrix deposition. Our group and others have previously demonstrated the beneficial effects of 17β-estradiol treatment across a range of preclinical wound models. Here we asked whether oestrogen would effectively promote healing in our LPS bacterial infection model. Intriguingly, co-treatment with 17β-estradiol was able to promote re-epithelialisation, dampen inflammation and induce collagen deposition in our LPS-delayed healing model. Collectively, these studies validate K. pneumoniae-derived LPS treatment as a simple yet effective model of bacterial wound infection, while providing the first indication that oestrogen could promote cutaneous healing in the presence of infection, further strengthening the case for its therapeutic use.

The impact of tele-advice on the community nurses' management of leg ulcers

Peters, J. Melanie January 2003 (has links)
This study attempted to investigate the impact of new technology, specifically tele-advice on community nurses' care of leg ulcers. Firstly, a stratified randomised controlled study was designed to measure the impact of using this technology on their levels of wound knowledge and confidence. An individual self-test questionnaire and an attitudinal scale measured nurses' knowledge and confidence respectively both pre and post-intervention. Secondly, a new visual wound assessment tool was designed to represent the state of the wound by a single numerical value; the State of the Wound Index (SWI). Thirdly, the impact of nurses' knowledge, confidence and patient variables was explored to assess their impact on the state of the wound as represented by SWI. The sample consisted of thirty-eight registered primary care nurses from two local NHS trusts in South Wales and their corresponding 38 patients with venous leg ulcers. Nurses were stratified according to their qualifications into experimental or control groups. Both groups were shown to have comparable levels of knowledge and confidence pre-intervention. Nurses in the experimental group received expert tele-advice by a Clinical Nurse Specialist (CNS) over a 12 week period regarding the care of their patient's leg ulcer, whilst those in the control group continued to care for their leg ulcer patients in the traditional way. hi the experimental group, nurses' level of knowledge increased significantly (p=0.02) whilst no improvement was observed for the control group. In terms of confidence, the experimental group reached near significance when extremely positive statements were excluded with no improvement observed for the control group. Results show that the intervention had a positively significant impact on nurses' wound care knowledge and level of confidence. A set of 18 tele-transmittable wound factors was identified by a panel of wound experts. These factors were ranked by another independent panel of leg ulcer experts and no significance could be established in their order of importance. These factors were then examined for their highest and lowest possible estimates for every wound in the sample both pre and post intervention using a Visual Analogue Scale (VAS). These estimated values formed the basis for 95% confidence interval estimates from which 100 virtual nurse assessed values were generated. These values were then used to generate SWI. This new index ranged from 0 (best possible state) to 100 (worse possible) and was seen to reliably increase when the wound deteriorated and decrease as the wound improved. Linear regression models were built to establish the relationship between SWI, patient variables and nurses' knowledge and confidence levels pre and post-intervention. These indicated that knowledge and confidence can have a positive impact on the healing process. This study has shown that there is great potential for the use of tele-advice in community nurses' care of leg ulcers. For this to succeed, it is recommended that further pre and post registration nurse training is provided to enhance their knowledge in wound care, especially in the areas of physiology and wound assessment.
