OBJECTIVE： To provide reference for improving the work quality of Pharmacy intravenous admixture service （PIVAS）. METHODS： The quality control monitoring system for PIVAS established and implemented in our hospital was introduced， the monitoring system was tracked and checked from initial stage of implementation （Jan. 2016） to implemented for 12 months （Dec. 2016）， and the effect was evaluated. RESULTS： PIVAS in our hospital had developed quality control monitoring system that included medication error and critical error monitoring system， auditing medical order homogenization monitoring system， hand hygiene monitoring system， high-alarm drug management monitoring system and drug liquid residue monitoring system. In initial stage of implementation， the relevant checking indexes including incidence of medication error and critical error， standardization rate of auditing medical orders， awareness rate of hand hygiene knowledge， compliance rate of hand hygiene， correct rate of hand hygiene， pass rate of high-alarm drug management and pass rate of drug liquid residue were 0.14％， 57％， 85％， 70％， 86％， 98％， 75％； and after implemented 12 months， the indexes were 0.01％， 87％， 97％， 81％， 95％， 100％， 93％， respectively （P＜0.05）. CONCLUSIONS： The quality control monitoring system in PIVAS established and implemented in our hospital has effectively improved the work quality of PIVAS.
