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

IntroductionThe 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. Patients and methodsThis 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. Results19800 patients were included, predominantly women (63%), with a mean age of 53.7±20 years. The prevalence of CVD (CEAP categories C1–C6) was 48.5% (95% CI, 47.8–49.2), significantly higher in women (58.5%; 95% CI, 57.6–59.4) than in men (32.1%; 95% CI, 31.0–33.1). 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. ConclusionChronic 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.
