The prevalence and incidence of wounds is predicted to rise due to an ageing population, that is also likely to have an increasing number of comorbidities (Dowsett et al, 2017). This trend will invariably result in increased costs to the NHS. The estimated annual cost of wound management in 2017/2018 was £8.3 billion. The cost of managing 70% of wounds which healed was £2.7 billion while it cost £5.6 billion managing only 30% of unhealed wounds (Guest et al, 2020). In view of these figures, it is important that health professionals (HPs) recognise wounds that are not progressing to healing at an early stage and implement all available treatment modalities to ensure that the wound does not become non-healing or stalled. Therefore, this article defines non-healing wounds, how to identify wounds at risk of becoming non-healing and the timely implementation of advanced treatment modalities, such as single use negative pressure wound therapy (sNPWT).
