<p>As the prevalence and incidence of wounds are predicted to increase due to an ageing population with increasing comorbidities, reducing the burden of wounds by optimising healing is seen as a key factor in lowering wound care costs. Inappropriate or delayed treatment adversely affects the time to wound healing, impacting quality of life, and increasing the burden on patients, their families and carers, society and the health economy. Identifying non-healing wounds is vital to cost reduction. Failure to recognise wounds not progressing towards healing increases the subsequent risk of non-healing and places the patient at unnecessary increased risk of wound complications.</p>
