Debridement is the removal of non-viable tissue from the wound bed and surrounding skin and is an important part of wound healing and wound bed preparation. Devitalised tissue, such as necrosis, slough and hyperkeratosis, interfere with the process of wound
healing. When a wound fails to progress, there is a need to assess the wound bed and surrounding tissue and promote an optimum environment that encourages the formation of healthy granulation tissue (Young, 2014). Recent advances in debridement techniques
using monofilament fibre technology can be practised by nonspecialist nurses and used safely and effectively in a patient’s home. In a recent audit, a dataset of 486 patients who had been newly prescribed a monofilament fibre debridement pad was obtained to
validate clinical effectiveness and cost efficiency. The total cost of wound care prescribing fell by 14% or £101,723 in the six months after the intervention compared with the six months before. The average monthly expenditure per patient fell from £244 before the intervention to £209 after (Burnett et al, 2021). This evidence reinforces the National Institute for Health and Care Excellence (NICE) recommendations for use of monofilament fibre debridement in the community, based on evidence of its effectiveness and estimated cost savings (NICE, 2019).

This article describes the wound infection continuum in surgical, acute and chronic wounds. The phases are: contamination, colonisation, local infection and finally spreading and systemic infection. Clinicians need to be familiar with the signs and symptoms of local infection in order to put strategies in place to prevent a ‘full blown’ wound infection and to recognise how the signs and symptoms differ by wound type. The article looks at the
most recent guidance on wound infection management strategies, together with the identification and treatment of suspected biofilms and the two-week challenge, used in clinical practice to disrupt biofilms. Wound cleansing and the use of antimicrobial dressings
and topical antiseptics are also discussed.

It can be a bit daunting when you are faced with a complex, chronic wound that is failing to progress. What makes a chronic wound hardto- heal and where do you start with its management? It can also be challenging for patients because the wound may be affecting their quality of life, often causing a high volume of exudate, increased pain or discomfort and malodour (Atkins et al, 2019). This article describes what can make a wound become hard-to-heal and offers guidance on assessment and management and how the use of a collagen wound dressing, Cutimed® Epiona (Essity), can help promote wound healing.

In each issue we investigate a hot topic currently affecting you and your community practice.

Evidence suggests that biofilm is present in at least 78% of nonhealing wounds, and it is widely accepted that its presence may be a cause for delayed healing in some patients. As the majority of chronic wounds are managed in a community setting, it is important that clinicians have an understanding of what biofilm is, how to identify its presence in the wound, and how to carry out biofilm-based wound care (BBWC). AQUACEL® Ag+ Extra™ is a unique dressing that has been specifically designed to manage biofilm. It combines antimicrobial and anti-biofilm components, which work in synergy to successfully disrupt biofilm, expose microorganisms to the broadspectrum antimicrobial activity of ionic silver in chronic wounds and to help prevent biofilm re-formation, thus making it worthy of inclusion in the biofilm care pathway.
