Objective To develop an intelligent task assignment software for operating room′s auxiliary personnel and to explore the effect of the software. Methods A total 509 surgeries performed in March 2018 were recruited into the intervention group, and the auxiliary personnel of the surgeries were managed with an intelligent task assignment software which had been developed by referring to an order dispatch model. Another 486 surgeries performed in the same period were enrolled into the control group, and the auxiliary personnel of the surgeries were managed with routine measures.The management effect were compared. Results The inte-rvention group had shorter task responding time and completion time, than the control group; and operating room nurses′ satisfaction was significantly higher than before (P＜0.01 for all). Conclusion The order dispatch system accurately recorded the auxiliary personnel′s workload and on-duty time, which improved their working efficiency, and operating room nurses′ satisfaction. The system also boosts scientific and refined management of logistical service.
