Chronic oedema and leaking lymphorrhoea can be distressing and challenging for patients to live with. This article introduces the Chronic Oedema 'Wet Leg' Pathway, which became an output from the Lymphoedema Network Wales 'On the Ground Education Project' ( Thomas et al, 2017 ). The evidence-based pathway provides nurses and therapists with clear guidelines to support prompt, efficient and effective management of all patients with chronic oedema and wet legs. This article presents the evidence and demonstrates the benefits of timely active treatment for all patients with leaking lymphorrhoea, which includes decreasing pain and improving mobility and daily activities. Other benefits include reducing the risk of cellulitis and the development of chronic wounds. The pathway also demonstrates opportunities for the NHS by decreasing both the number of community nursing visits and the number of wound dressings used. By actively treating symptoms-rather than simply mopping up the leaking lymphorrhoea-this pathway demonstrates value-based health care by reducing waste, harm and variation within the NHS.
