As lymphoedema prevalence continues to rise causing increasing demand for services, optimising patient self-management is vital. In the UK, lymphoedema treatment models have traditionally followed the ‘four cornerstones’ approach, including skin care, compression therapy, physical activity, and lymphatic drainage massage. These address the physical manifestations of lymphoedema yet neglect the psychological and emotional impact. Since the establishment of the psychology service within the Lymphoedema Wales Clinical Network (LWCN) in 2023, a more holistic model of care has been introduced into clinical practice. This development reflects a growing recognition of the psychological burden associated with lymphoedema and the need for integrated support services. The introduction of the lymphoedema COMPASS treatment model represents a significant advancement in routine care delivery, combining physical and psychological interventions to support patients to live as well as possible with lymphoedema. The COMPASS model is designed to place individuals at the centre of their care, promoting active engagement and self-management. It supports and encourages patients to take ownership of their condition, including the emotional and psychological challenges that often accompany lymphoedema.
