Objective To design a tool of quantitative assessment for the comprehensive benefit of the large medical equipments before purchase. This tool provides a basis to verify a large medical equipment purchase for the health administrative departments to improve the utilization efficiency of the medical equipments. Methods We explored to construct an index system as a tool of quantitative assessment for comprehensive benefit of MRI before purchase in county-level hospitals and examined its effectiveness. We also designed certain models for quantitative analysis on social benefit of large medical equipments as an innovative exploration based on investigation,comprehensive analysis and Delphi method. Results The index system for quantitative assessment on comprehensive benefit of MRI before purchase in county-level hospitals was established and proved by practice as an operable and efficient tool. The models for quantitative analysis of social benefit were designed as part of the system. Conclusions Index system combined with designed models is an effective solution to realize the quantitative assessment on comprehensive benefit of large medical equipments before purchase.
