METHODS： The factors affecting the timeliness of finished product infusion distribution were analyzed in terms of personnel， software/hardware， and relevant measures were developed. The distribution of long-term medical orders’ planning execution time and actual execution time in Jan.-Jun. 2015 （before improvement） and Jan.-Jun. 2016 （after improvement） were summed up， as well as the average time in each link of PIVAS packing-delivery/infusion sending-clinical reception-actual execution time， and the effects were evaluated. RESULTS： For the personnel， software/hardware and other aspects of the factors， measures were developed and implemented， including strengthening the communication of clinicians （issued medical orders） and nurses （performed medical orders） in related information， improving professional level and ability of pharmacists that reviewing medical orders in PIVAS， optimizing information system functions and improving related systems in PIVAS. Compared with the same period in 2015， peak time distribution was dispersed in medical orders’ planning execution time and actual execution time in 2016. The average time of delivery/infusion sending-clinical reception decreased by 10.13 min， and the time of each link in 2016 showed a slight downward trend month by month. CONCLUSIONS： The management improvement measures in PIVAS of our hospital have improved the timeliness of finished product infusion distribution， and provided a guarantee for the timely treatment of clinical patients.
