Introduction: Chronic oedema a progressive and under-recognised condition that indicates lymphatic system insufficiency. It encompasses lymphoedema, venous oedema, dependency oedema, cancer-related oedema, obesity-related oedema, lipo-lymphedema, and mixed or multifactorial oedemas. If not effectively managed, chronic oedema can result in complications such as recurrent cellulitis, skin and tissue changes, functional disability, pain, disfigurement, and, in severe cases, increased risk of mortality. Background: The prevalence of chronic oedema is growing with the ageing population and rising rates of obesity, vascular disease, and cancer survivorship. Despite its significant burden, early detection and timely intervention are often missed. Cellulitis, a common complication, frequently leads to emergency presentations and hospital admissions, particularly among patients with undiagnosed or poorly managed oedema. Modalities such as compression therapy, skin care, elevation, movement, weight management and patient education remain underutilised. Discussion: There is an urgent need for a coordinated, system-wide approach to managing chronic edema. This includes: early identification and proactive management, integrated and interdisciplinary models of care, workforce education and training, timely referral to lymphoedema specialists, the use of digital tools and telehealth, and clinical leadership. Advanced practice vascular nurses can lead change and bridge service gaps, champion education, advocate for compression therapy, and guide the management of complex wounds or cellulitis. Nurse-led models of care ensure patients are managed holistically, reducing preventable hospitalisations and improving outcomes. Conclusion: A strategic, system-wide solution is essential to improve outcomes for patients with chronic oedema. Advanced practice vascular nurses will be pivotal in delivering high-quality, person-centred care, empowering patients, and leading service redesign to address this silent epidemic.
