ABSTRACT
Objective To apply six sigma management method to optimizing flow,enhancing treatment quality,prolonging service life and decreasing purchase cost of the non-coated surgical instrument.Methods The treatment flow of the noncoated surgical instrument was optimized through five steps of six sigma method including defining,measuring,analyzing,improving and controlling.The treatment results before and after flow optimization were compared,analyzed and evaluated.Results The rates for corrosion and rejection were both decreased significantly after flow optimization,while the quality was increased obviously (P＜0.05).Conclusion Six sigma management method involved in the treatment of the non-coated surgical instrument saves purchase cost,enhances the efficiency of disinfection supply room and facilitates effective supervision and monitoring.
