Background: Use of new technology can lead to changes in the treatment course for patients and in treatment costs for the health service. The aim of this study was to compare sickness absence and time to resumption of daily activities, as well as treatment costs, for two surgical treatments for varicose veins: endovenous steam ablation and vein stripping.
Material and method: This prospective observational study included 46 patients treated with steam ablation and 37 treated with vein stripping in the period 2015-2016. The two groups were matched with respect to age, sex, occupational status and classification. After treatment, patients were interviewed every other week until daily activities had been resumed. Detailed information on expenditure related to personnel, equipment, premises and materials was used to calculate the cost of treatment.
Results: Patients treated with steam ablation resumed daily activities after a median of 0 (interquartile range 0-2) days versus 4 (2-7) days for vein stripping (p < 0.001), and sporting activities after 4 (2-9) days versus 11 (3-19) days (p < 0.004). For patients in employment, sickness absence after steam ablation was 2 (2-5) days versus 14 (6-21) for patients treated with vein stripping (p < 0.001). The estimated treatment cost for steam ablation was NOK 5 973, compared with NOK 10 109 for vein stripping.
Interpretation: Steam ablation led to shorter convalescence and sickness absence for the patient, and lower costs for the hospital. Reduced sickness absence also implies lower costs for society.
