Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
(1) Sterile larvae therapy
Ward nurses will apply the wound therapy. Sterile larvae therapy (medical grade): The normal rate of application is 5-8 larvae per cm2 of wound surface area. The larvae are left on the wound site for 48-72 hours therefore wound dressings will be changed and sterile larvae therapy applied every 2-3 days. Wound assessment will be completed at each dressing change and includes assessment by treating nurses and patient reported assessment (rating pain, odour etc).

(2) Standard wound management practices which vary according to the wound.

Allocation is determined by participant consent.
Intervention code [1] 314532 0
Treatment: Other
Comparator / control treatment
Standard wound treatment: the most appropriate treatment for a each wound, based on assessment of the wound by treating nurses and doctors. This is based on current evidence around wound management.
Control group
Active

Summary
Brief summary
Non-healing soft tissue and malignant wounds can be very challenging to treat in the palliative care setting. Instead of complete healing, the goals of care in this setting are to reduce symptoms such as malodour, exudate and pain, to maintain patients’ dignity and to improve quality of life. This study aims to investigate the use of sterile larvae therapy in treating non-healing soft tissue and malignant wounds in the palliative care setting.
