Objectives

To analyze the cost-effectiveness of current technologies (conservative care [CONS], high-ligation surgery [HL/S], ultrasound-guided foam sclerotherapy [UGFS], endovenous laser ablation [EVLA], and radiofrequency ablation [RFA]) and emerging technologies (mechanochemical ablation [MOCA] and cyanoacrylate glue occlusion [CAE]) for treatment of varicose veins over 5 years.

Methods

A Markov decision model was constructed. Effectiveness was measured by re-intervention on the truncal vein, re-treatment of residual varicosities, and quality-adjusted life-years (QALYs) over 5 years. Model inputs were estimated from systematic review, the UK National Health Service unit costs, and manufacturers’ list prices. Univariate and probabilistic sensitivity analyses were undertaken.

Results

CONS has the lowest overall cost and quality of life per person over 5 years; HL/S, EVLA, RFA, and MOCA have on average similar costs and effectiveness; and CAE has the highest overall cost but is no more effective than other therapies. The incremental cost per QALY of RFA versus CONS was £5,148/QALY. Time to return to work or normal activities was significantly longer after HL/S than after other procedures.

Conclusions

At a threshold of £20,000/QALY, RFA was the treatment with highest median rank for net benefit, with MOCA second, EVLA third, HL/S fourth, CAE fifth, and CONS and UGFS sixth. Further evidence on effectiveness and health-related quality of life for MOCA and CAE is needed. At current prices, CAE is not a cost-effective option because it is costlier but has not been shown to be more effective than other options.
