Abstract: Objective To optimize the emergency infusion process and provide patients with efficient,comfortable and safe infusion services. Methods We optimized patient payment and delivery of medication process to reconstruct the emergency infusion process based on intelligent settlement system and hospital logistics information system. The convenience sampling method was used to select the infusion patients in the peak period of emergency treatment of a tertiary class A general hospital in Zhejiang Province from May to July 2021 as the control group,and the infusion patients in the peak period of emergency treatment from August to October 2021 as the experimental group. The experimental group adopted the reconstructed infusion process. Collect and compare the waiting time for infusion,the time from the beginning of skin test to medication,drug damage rate,and patient satisfaction between the two groups. Results A total of 236 emergency infusion patients were included in this study,including 121 patients in the experimental group and 115 patients in the control group. The time from the doctor's prescription to the patient's infusion puncture in the experimental group was 18.0（13.0,23.0）min,which was significantly shorter than that in the control group 29.0（19.0,49.0）min（Z=-6.889,P<0.001）. The time from the beginning of skin test to the application of medication in the experimental group was（36.32±6.31）min,which was shorter than that in the control group（55.50±5.72）min（t=-9.674,P<0.001）. No drug damage occurred in the experimental group. The satisfaction of patients in the experimental group was 93.4%,higher than that in the control group（Z=-7.197,P<0.001）. Conclusion Emergency infusion process reengineering shortened the waiting time of patients for infusion,ensured the safety of infusion medication,and improved patient satisfaction.
