Prevalence of chronic venous insufficiency in workers of the Hospital de Alta Complejidad El Calafate in Argentina

Abstract

Introduction: Chronic venous insufficiency (CVI) is a frequent, yet underdiagnosed condition associated with significant health, social, and occupational impact. Prolonged standing has been identified as a crucial occupational risk factor.
Objective: To estimate the prevalence of symptomatic CVI among healthcare workers at the Hospital de Alta Complejidad El Calafate (Argentina), identify risk factors, and provide evidence for preventive strategies.
Methods: A cross-sectional observational study was conducted between February and April 2024. An anonymous, semi-structured, self-administered digital survey was distributed to all permanent staff (n = 588). Independent variables included sociodemographic, occupational, and clinical factors. The dependent variable was the self-reported presence of CVI symptoms. Logistic regression models were used to assess associations.
Results: A total of 239 valid responses were analyzed (response rate: 40.6%). Participants were predominantly women (74.9%), with a median age of 40 years (interquartile range, 34-47 years). Mean body mass index was 27.9 (standard deviation: 5.27); 27.6% met criteria for obesity, although only 17.6% self-identified as obese (p < 0.0001). Significant associated factors included female sex, prolonged standing ≥3 hours, family history of varicose veins, and arterial hypertension. Women reported a higher prevalence of CVI symptoms, as well as higher exposure to hormonal therapy and multiple pregnancies.
Conclusion: The prevalence of CVI symptoms in healthcare workers at a highcomplexity hospital was considerable, particularly among women and those with occupational and familial risk factors. These findings support the implementation of preventive measures tailored to high-risk hospital staff.
