Subjects exposed to occupational standing are at risk of developing chronic venous disease. Graduated compression stockings (GCS) counteract venous hypertension. Aim of the present investigation was to assess GCS clinical and cost effectiveness in prolonged standing up workers. Randomized controlled trial involving 75 healthy healthcare professionals working in 6 hours standing up shifts without or with GCS (group A and B, respectively). Outcome measures were performed before and after the shift, at baseline (T0), at 1 (T1), 6 (T6) and 12 (T12) months and included lower limb volume, air plethysmography (APG), quality of life, and dedicated cost-effectiveness questionnaires. Seventy-two subjects completed the data collection. Leg volume increased in group A and decreased in B at all assessment points (T0, 1, 6, 12) (P<0.0001). Venous filling index didn't change within the 12 months, but, after every shift, its value was lower in B compared to A (P<0.0001). At 12 months, VVSymQ worsened in A and improved in B (P<0.0001) and CIVIQ significantly worsened in A (P<0.0001), while in B it significantly improved (P<0.0001). Perceived disability was higher in A at 12 months (P<0.001) and the cost calculation revealed a saving of 1510 euro per year in B. GCS counteracted occupational oedema and positively influenced venous filling index, while improving vein specific quality of life measurements in addition to cost savings.
