Leg ulcers: epidemiology and aetiology.

J V Cornwall, C J Doré, J D Lewis

    The British Journal of Surgery
    |September 1, 1986
    PubMed
    Summary

    Leg ulcer prevalence in the region was 0.18%, with higher rates in those over 40. Many chronic leg ulcers went untreated, highlighting a need for better community-based care and assessment services.

    Area of Science:

    • Vascular Medicine
    • Epidemiology
    • Community Health

    Background:

    • Leg ulcers represent a significant health burden, with high prevalence and chronicity.
    • Many patients with leg ulcers lack access to timely and effective healthcare services.
    • Understanding the underlying vascular pathology is crucial for appropriate management.

    Purpose of the Study:

    • To determine the prevalence of leg ulceration in a defined regional population.
    • To investigate the aetiology of leg ulcers, focusing on venous and arterial circulation.
    • To assess the current service provision and identify areas for improvement.

    Main Methods:

    • Prevalence study in a regional Health District.
    • Patient data collection including lesion duration and prior healthcare attendance.
    • Vascular assessment using ultrasound and photoplethysmography in a random sample of patients.
    • Calculation of the mean pressure index for patients with an ischaemic element.

    Main Results:

    • Overall leg ulcer prevalence was 0.18%, rising to 0.38% in individuals over 40.
    • Fifty percent of lesions were chronic (present >1 year), and 62% of patients had no prior hospital attendance.
    • Vascular investigations revealed deep vein incompetence (38%), superficial vein incompetence (43%), and an ischaemic element (31% with mean pressure index of 0.62).

    Conclusions:

    • Leg ulcers are prevalent, often chronic, and frequently undiagnosed or untreated.
    • A significant proportion of leg ulcers have underlying venous or arterial insufficiency.
    • Integrated community-based services with objective assessment tools can improve care for leg ulcer patients.
