Objective: To investigate the effectiveness of using quality control circle (QCC) techniques to reduce the cost of non-priced consumables in medical oncology. Methods: Analytic statistics were compiled on the performance appraisal form. Aiming at the key points of improvement with respect to the excess cost of non-valuable consumables, the reasons were analyzed, and corresponding measures were formulated to compare the cost before and after the improvement. Results: After the QCC activity, the cost of non-priced consumables decreased from RMB 6.57/bed day to RMB 3.96/bed day. Conclusion: QCC has effectively reduced the cost of non-priced consumables in the oncology department, and it is worthy of promotion.
