Objective: To evaluate the results of the expanded National Venous Screening Program (NVSP) as administered by the American Venous Forum. Methods: Eighty-three physicians across 40 states participated in screening Americans for venous disease. The NVSP instrument included demographics, venous thromboembolism (VTE) risk assessment, quality-of-life (QOL) assessment, duplex ultrasound scan for reflux and obstruction, and clinical inspection. Participants received educational materials and a report card to give their physician. Results: A total of 2234 individuals underwent screening (mean, 26 people/site; range, 4-42). Demographic data observed included mean age of 60 years (range, 17-93 years); 77% female; 80% Caucasian; mean BMI of 29 (range, 11-68); 40% current or previous smoker; and 24% taking antiplatelet therapy and 4% taking warfarin. If placed in a situation conducive for VTE, 40% of participants were low risk, 22% were moderate risk, 21% were high risk, and 17% were very high risk. On a venous QOL assessment, 17% had a combined total score for all 11 questions of "very limited" or "impossible to do." Reflux or obstruction was noted in 37% and 5% of participants, respectively. CEAP class 0 to 6 was 29%, 29%, 23%, 10%, 9%, 1.5%, 0.5%, respectively. Discussion: Despite a dramatic expansion in the second annual NSVP (from 17 to 83 centers), the presence of venous disease observed in a larger screened population continues to be high. The NVSP represents one pathway to increasing public awareness about venous disease.
