Objective: To examine the use of maggot debridement therapy (MDT) for individuals with diabetic foot ulcers (DFU) after a change in prescribing policy.

Method: A self completion survey/structured questionnaire to assess healthcare professionals' existing knowledge of MDT was given to those specialist services providing wound care treatments for DFUs.

Results: The results showed that those responding had a basic understanding of MDT and its use. However, further education is required for the type of wounds that maggots can be applied to, and what enzymes are produced. Enablers and barriers to MDT use also included policy and procedures, time constraints and the 'yuck factor'.

Conclusion: While there is good clinical evidence to support the use of MDT, there is a lack of evidence examining the factors that influence healthcare professionals’ decisions to recommend this treatment.

Background: Pressure damage in paraplegic patients is difficult to manage due to their limited mobility. Topical Negative Pressure Therapy (TNPT) has successfully been used for different types of wounds, including cavity wounds, leg ulceration and pressure ulcers (PU). The introduction of TNPT with instillation (TNPTi) has increased the categories of wounds that can be treated. Aim: To describe the wound management of an unstageable pressure damage with underlying osteomyelitis. Methods: Observation of the care provided to a patient presenting with an unstageable pressure damage on admission. On further investigation osteomyelitis was found. Results: Following 3 months of the application of TNPTi, the wound size had reduced significantly, making it suitable for flap surgery. The benefits of undertaking flap surgery after an overall short time thanks to this treatment includes also the psychological and social aspects of the patient’s life. This also reflected in a positive impact on the patient's wellbeing and reduced length of hospitalisation. Conclusions: The use of TNPTi positively affected the healing process of an unstageable PU presenting with osteomyelitis. Further studies are needed to validate the effectiveness this treatment regimen.

      In the diabetic foot, loss of autonomic nerve supply can alter the vascular perfusion and nerve supply of the skin. This affects the integrity of the skin and its resistance to mechanical and chemical trauma from pressure and wound exudate (Faber et al, 1993). Maceration is a common problem, particularly in the management of chronic wounds (Thomas, 1997). Moreover, diabetic foot ulceration continues to be synonymous with delayed healing, higher infection rates and an increased risk of lower-extremity amputation (Frykberg, 1998). Several factors can affect the local wound environment in diabetic foot ulceration, such as hyperglycaemia, macrovascular and microvascular disease, polyneuropathy, and impaired host immunological defence (Kamal et al, 1996). Maceration of the wound bed and surrounding skin in diabetic foot ulceration may be one of the least well-recognised factors contributing to impaired healing (Cullum et al, 2000). The impact of maceration on skin integrity, and its traditionally poor management and frequency, make it an obvious contender for inclusion as a risk factor in wound care (Cutting and White, 2002b). However, there is little research on the possible implications of maceration in diabetic foot ulceration (Bale et al, 2001). The aims of wound management are to address patient concerns, correct intrinsic and extrinsic factors where possible, and optimise the healing environment. It is also essential to include the periwound margins as an integral part of wound assessment (Cutting and White, 2002a).

This article explores medical-device related pressure ulcers (MDRPU) in an intensive care unit (ICU) at the Royal United Hospitals Bath NHS Foundation Trust (RUH). The data presented outlines a reduction in PU of 66% over a 6-year period and a reduction in MDRPU of 50% over the same period. MDRPU were particularly challenging to prevent in ICU during the COVID-19 pandemic, where there were additional numbers of patients in the ICU with medical devices in place. Additionally, during the COVID-19 pandemic, an increased number of patients in the ICU were nursed prone (face down), adding additional pressure on the facial structure, a range of measures were put in place to avoid those avoidable MDRPU in the ICU at the RUH. Measures focused on skin checking, offloading and rotation of devices, including endotracheal tubes, non-invasive ventilation, nasogastric (NG) and nasojejunal (NJ) tubes and catheters. A specific comfort and pressure care record was developed for ICU to record the assessments of these at risk areas.
