OBJECTIVE: To probe into the effect of PDCA cycle management on the application of traditional Chinese medicine injection for activating blood and dissolving stasis in surgery department in the Pukou Hospital of Nanjing（ hereinafter referred to as "our hospital"）

and to promote clinical rational medication. METHODS: PDCA model was adopted to find out the irrational application of traditional Chinese medicine injection for activating blood and dissolving stasis in our hospital

so as to analyze the reason

formulate improvement measures

implement supervision and inspection and continuous improvement; the usage rate

consumption sum

defined daily dose system（ DDDs） and irrational application of traditional Chinese medicine injection for activating blood and dissolving stasis were analyzed and compared before and after the implementation of PDCA. RESULTS: After 2 stages of PDCA intervention

the accumulative consumption sum and its proportion and accumulative DDDs of traditional Chinese medicine injection for activating blood and dissolving stasis in our hospital had been significantly lower than those of before intervention

with statistically significant differences（ P<0. 05）; after the second stage of PDCA intervention

the usage rate of traditional Chinese medicine injection for activating blood and dissolving stasis in surgery department in our hospital had been significantly lower than that of the first stage and before intervention

with statistically significant differences（ P<0. 05）.CONCLUSIONS: The application of PDCA cycle management can promote rational application and management of traditional Chinese medicine injection for activating blood and dissolving stasis in surgery department in our hospital.
