RESUMO
INTRODUCTION: Current localization techniques used in breast conserving surgery for non-palpable tumors show several disadvantages. Magnetic Seed Localization (MSL) is an innovative localization technique aiming to overcome these disadvantages. This study evaluated the expected budget impact of adopting MSL compared to standard of care. METHODS: Standard of care with Wire-Guided Localization (WGL) and Radioactive Seed Localization (RSL) use was compared with a future situation gradually adopting MSL next to RSL or WGL from a Dutch national perspective over 5 years (2017-2022). The intervention costs for WGL, RSL and MSL and the implementation costs for RSL and MSL were evaluated using activity-based costing in eight Dutch hospitals. Based on available list prices the price of the magnetic seed was ranged 100-500. RESULTS: The intervention costs for WGL, RSL and MSL were respectively: 2,617, 2,834 and 2,662 per patient and implementation costs were 2,974 and 26,826 for MSL and RSL respectively. For standard of care the budget impact increased from 14.7m to 16.9m. Inclusion of MSL with a seed price of 100 showed a budget impact of 16.7m. Above a price of 178 the budget impact increased for adoption of MSL, rising to 17.6m when priced at 500. CONCLUSION: MSL could be a cost-efficient localization technique in resecting non-palpable tumors in the Netherlands. The online calculation model can inform adoption decisions internationally. When determining retail price of the magnetic seed, cost-effectiveness should be considered.
