title: Prevalence and clinical characteristics of chronic venous disease in patients seen in primary care in Spain: results of the international study Vein Consult Program.
abstract: BACKGROUND
  The aim of this study was to evaluate the prevalence, clinical characteristics and management of chronic venous disease (CVD) in patients seen at primary care clinics
  
  
  METHODS
  This cross-sectional study was carried-out in Spain by 999 primary care physicians. They recruited 20 consecutive patients who were attending their clinics for any reason except for a medical emergency. The following Information was collected: demographic data, CVD risk factors, physical examination, clinical characteristics of the CVD and how it was managed.
  
  
  RESULTS
  19,800 patients were included, predominantly women (63%), with a mean age of 53.7 ± 20 years. The prevalence of CVD (CEAP categories C1 to C6) was 48.5% (95% CI, 47.8 to 49.2), significantly higher in women (58.5%; 95% CI, 57.6 to 59.4) than in men (32.1%; 95% CI, 31.0 to 33.1). The greater the age the higher the prevalence and the more advanced the CVD. Ninety-nine percent of the patients required some form of treatment, with a greater proportion among women (72% vs. 39%, P<.0001). Sclerotherapy, endothermal ablation or surgery was required by 4% of the patients. Referral to the specialist was considered for 7% of the patients.
  
  
  CONCLUSIONS
  Chronic venous disease is highly prevalent among patients seen at primary care clinics in Spain, especially in women and elderly patients. Referral to a specialist and/or the use of the more invasive treatment procedures is uncommon.
