Abstract
BACKGROUND: In mid-2007, endovenous ablation (EVA) of the great saphenous vein was introduced into the publicly funded health care system in Saskatchewan, Canada. We hypothesize that the introduction of EVA resulted in a decrease in use of high ligation and stripping (HL/S), decreased costs to the health care system, and increased demand of patients for great saphenous vein ablative procedures. METHODS: We retrospectively reviewed administrative data to capture cases of HL/S between 2003 and 2014 and cases of EVA of the great saphenous vein (endovenous laser treatment and radiofrequency ablation) between 2007 and 2014. Accounting for the change in practice pattern that occurred slowly between 2007 and 2009, we divided our patients into the pre-EVA era (2003-2006) and the post-EVA era (2010-2014). Procedure costs were determined with models used by our health region for this purpose. RESULTS: Utilization rates for great saphenous vein intervention remained similar in the pre-EVA (90 procedures per year) and post-EVA (92 procedures per year; P = .83) eras. Case costs of HL/S ($1965.12/case) were higher than those of EVA (endovenous laser treatment, $1295.08/case; radiofrequency ablation, $1410.54/case). The total annual costs of great saphenous vein intervention decreased from $176,861 in the pre-EVA era to $134,525 (P = .02). CONCLUSIONS: Introduction of publicly funded EVA has reduced rates of HL/S and reduced costs to our health system by approximately $42,000 per year, without increasing great saphenous vein intervention rates.
