BACKGROUND: Current prevalence estimates of chronic leg ulceration are frequently based on studies from the 1980s. During the last decade, major changes have occurred in the application of evidence-based practice to this condition. AIM: To determine the prevalence and cause of leg ulceration in a defined geographical population after 8 years of providing standardized evidence based protocols of care. DESIGN: Prospective survey. METHODS: Patients with leg ulceration of >4 weeks duration) within an integrated acute and community leg ulcer service were ascertained, interviewed and clinically assessed, using a standardized questionnaire on medical history, ulcer details and non-invasive vascular investigation to describe causes. Ulcers were classified by aetiology. RESULTS: We identified 113 patients in a population of 252 000, giving a crude prevalence of 0.45/1000 (95%CI 0.37-0.54/1000): 0.34/1000 in men, 0.54/1000 in women. Rates were highly dependent on age, increasing to 8.29 (men) and 8.06/1000 (women) in those aged >85 years. Of the responders, 62/113 (55%) had their ulcer for >1 year. Uncomplicated venous ulceration was observed in only 59/138 (43%) ulcerated limbs; a further 21 had ulceration primarily due to arterial disease. Complex causes were present in 48 (35%) limbs, mostly venous disease in combination with diabetes (35%), lymphoedema (42%) and rheumatoid arthritis (26%). DISCUSSION: Our prevalence of chronic leg ulceration is approximately one-third of that predicted by previous studies using similar methodologies in the 1980s. Patients with ulceration have more complex aetiologies than previously recognized, which may be a consequence of both increasing ulcer chronicity and age.
