Our research and development teams operate at a global level and generate synergies from our collective expertise and by drawing on related disciplines. We are also constantly exchanging information at an international level with independent technical institutions, key opinion leaders and multipliers in order to be able to ensure cooperation and knowledge management of the highest order. As part of this process, we also conduct extensive research, the results of which we continually present in workshops, at conferences and symposiums - either in documentation or talks given by our cooperation partners - and also publish in renowned scientific journals. This database contains a large number of these evidence-based scientific articles, most of which have been evaluated by independent assessors:
EVOLUTION OF A NATIONALLY ADOPTED VENOUS LEG ULCER BEST PRACTICE TREATMENT PATHWAY TO REFLECT NEW EVIDENCEPoster presented at EWMA 2019 05.06.2019 Gothenburg, Sweden
A National Best Practice Statement for the holistic management of venous leg ulcers¹ presents a treatment pathway, originally developed by Atkin and Tickle². The aim was to revise this treatment pathway to reflect new evidence³.
The treatment pathway was originally developed to reflect published RCT evidence for venous intervention reducing episodes of reoccurrence (ESCHAR trial)⁴ and with leg ulcer hosiery kits as first line as a result of the publication of the VenUS lV study⁵. The treatment pathway has been used since 2016 and needed further updating to reflect the recent evidence investigating the impact of early venous ablation in patients with venous leg ulcers (EVRA)⁶.
Results / Discussion:
In a group of 34 patients with leg ulceration the implementation of this pathway into everyday clinical practice has been shown after 3 months to deliver a number of benefits including increased healing rates, improved documentation and a reduction of nursing visits⁷;
From 0% to 76% having their leg ulcer diagnosis recorded
From 34% to 76% having their ABPI recorded
From 13% to 83% use of compression therapy
From 7% to 56% healing or signs of healing
43% reduction in nursing visits
It is vital to ensure that current research evidence is adopted within frontline services as soon as possible. Formalised evidence-based pathways provide a practical treatment guide and can help reduce unwanted variations, as standardising clinical processes through the use of a pathway is known to optimise the quality of treatments and improve patient satisfaction.
COMPREHENSIVE IN VITRO APPROACH FOR TESTING THE PERFORMANCE OF A HYDROACTIVE DRESSING (HAD) IN VITROPoster presented at EWMA 2019 05.06.2019 Gothenburg, Sweden
Maceration is the elixation of the skin by prolonged exposure to moisture impeding healing due to failure of skin protection and possible microbial infections. Chronic wounds are often colonized by different kinds of microorganisms, mostly S.aureus and P.aeruginosa. Bacterial load on the wound surface perpetuates an inflammatory environment. It is of interest to elucidate dressing performance by comprehensive in vitro testing including binding capacity for elastase, determination of antibacterial activity, and assessment of fluid handling capability.
A hydroactive dressing (HAD) consisting of cellulose/ethyl-sulfonate-cellulose fibres has been investigated. An in vitro maceration model was used to quantify and evaluate fluid uptake, fluid distribution, and shape changes. Binding capacity for elastase was determined over 24h. Determination of antimicrobial activity was performed according to JIS L 1902:2008 against S.aureus and P.aeruginosa.
HAD exhibited significantly higher fluid uptake than an alginate (AD) or a sodiumcarboxymethylcellulose dressing (SCD). It was shown that it possess a distinctly higher form stability. The SCD already macerated before the dressing was completely soaked while leakage with HAD and AD was only observed after they were completely gelled. HAD is further able to reduce the activity of elastase in vitro. And it exhibited a strong antibacterial activity against S.aureus and a significant antibacterial activity against P.aeruginosa.
Performance of dressings can be assessed and compared under standard conditions in vitro. Here, HAD is able to reduce elastase activity, inhibit bacterial growth, and possess superior fluid handling capacity compared to AD and SCD.Further versions

Achieving healing in a young adult with a venous leg ulcer using a biofilm pathway and short stretch bandagingPoster presented at Wound Care Today 2019 27.02.2019 Milton Keynes, UK
Liam is a 26 year old man who suffered a post trauma DVT when just 18 years old. He has Warfarin therapy and has a history of venous leg ulceration for 8 years. Because of the damage to his primary, deep veins he had developed a collateral venous circulation.
Liam describes having a leg ulcer at a young age as “life changing”. It stopped him playing sport and swimming and it changed how he interacting with friends. Because of his damaged circulation and medication he lived with the constant fear that his leg was going to deteriorate or bleed. Despite this, Liam continued to work full time and support his family.
In the summer of 2018, Liam’s nurse changes his treatment from a combination long-stretch cohesive bandage system, to a cohesive short stretch bandage system. She also implemented a Monofilament fibre biofilm based treatment regime to expedite wound bed preparation and disruption of the biofilm (Morris et al, 2016).
There was a dramatic reduction in leg oedema and improvement in leg shape almost immediately the new bandage system was started. Things continued to improve over the following months. Liam reported that the cohesive short stretch bandage system made “his leg feels much more comfortable with less ridging and less slippage”. His leg shape was much better, and it was easier to wear socks and shoes. Liam said that nobody noticed he had a bandage on.
In December 2018, after 8 years of ulceration, Liam’s venous leg ulcer healed.
This case study demonstrates how learning and implementing new knowledge, technology and skills can translate into improved patient outcomes. By sharing Liam’s story we can really understand the devastating effect a leg ulcer can have, especially on a teenager and young adult.
Liam now has a bespoke plan for the prevention of future venous leg ulcers which will include higher compression during working periods when he will be on his feet for long periods. This is achieved by using short stretch wrap systems to encourage continued self-care and ownership of his long term condition.Products Debrisoft Pad
Assessing the performance of an improved superabsorbent wound dressing:a multi-centre clinical evaluationPoster presented at CICA 2019 20.01.2019 Paris, France
This national, multicentre patient evaluation examines the enhancements that have recently been made to a superabsorbent dressing* and how this product improvement** has led to enhanced performance and improved patient related outcomes. The enhancements are a wider border and more ergonomic shape and a new structure to the superabsorbent polymer which increases absorbency.
The recently developed and improved superabsorbent wound dressing was evaluated in six clinical sites on 27 patients with wounds requiring management of exudate of varying levels.
The mean age of the patients who participated was 70 years and the main wound type was leg ulcer. At the start of the evaluation the surrounding skin was mostly reported to be macerated and/or red and excoriated. Exudate levels were light in 4 cases, moderate in 12 cases and heavy in 11 cases. The improved superabsorbent was used on its own as a primary dressing in only 5 cases and in combination with another primary dressing in 15 cases (7 did not answer the question). A topical antimicrobial was combined with the new superabsorbent in 60% of cases and a contact layer in 20% of cases. It was used under full or reduced compression in 21 cases. In most cases the improved superabsorbent replaced either another superabsorbent or absorbent dressing. The frequency of dressing changes varied from daily to weekly prior to the evaluation with 7 clinicians stating that the new and improved superabsorbent had reduced the frequency of dressing changes. The others either did not comment on this, or did not see a change. Other parameters were rated as good and very good and are outlined in Table 1.
Although the improved superabsorbent dressing includes a very effective wound contact layer, 20% of cases used the product in combination with another contact layer. Use with another contact layer would not be recommended as this is not necessary and increases costs. Superabsorbent dressings are designed for the management of medium to high levels of exudate and should not be considered in low exudate.
The new and improved superabsorbent wound dressing demonstrated clear advantages for clinicians managing exudate. The patient shown in Figure 1 - 3 is still being managed with the improved product as this is the only dressing he doesn’t react to.Further versionsFurther languages
ReadyWrap®: case studies in practiceBritish journal of community nursing 2019 24 2431
The cost that chronic wound care imposes on both patients and health services worldwide is well recognised. Most patients with venous leg ulcers require compression therapy over the long term, for both treatment as well as to prevent recurrence of these wounds. Caring for patients with chronic wounds makes up a large part of the workload for district and community nurses, and encouraging self-management among patients is a worthwhile effort to limit the costs and resources directed for this purpose. The present article describes the practical use of the ReadyWrap range of compression garments, which are available in various different styles, and aid patients, their families and carers in the self-management of venous leg ulcers. These products are designed with their long-term use in mind, and, as described in the case studies in this article, patients show good concordance to compression therapy involving ReadyWrap.PMID 31604036
