OBJECTIVEImprovement of the surgery instrument's clean quality, the optimized preparation way, reasonable arrangement in groups, raising the working efficiency.

METHODWe use the quality backward system into the instrument clean, the pack and the preparation way's question, carry on the analysis and the optimization, and appraise the effect after trying out 6 months.

RESULTSAfter finally the way optimized, instrument clean quality distinct enhancement; The flaws in the instrument clean, the pack way and the total operating time reduce; the contradictory between nurses and the cleans arising from the unclear connection reduces, the satisfaction degree of nurse and doctor to the instrument enhances.

CONCLUSIONSUsing of operating room quality backward system in the management of the instrument clean, the pack and the preparation way optimized, may reduce flaws in the work and the waste of human resources, raise the working efficiency.
