Objective To develop an intelligent scheduling system for surgery by setting up constraints in an intelligent working environment to achieve automatic scheduling of surgery and personnel,and to precisely match the sub-professional nurses for surgeries.Methods Scheduling constraints were set up,and finally efficient scheduling was developed.Results During the process of clinical application,the rates of error and omission for surgical schedule fell to 4.78％,the rate of surgery re-adjustment fell to 17.74％,the number of average daily operation increased,the matching degree of sub-professional surgery nurse post reached 94.71％.Conclusion The intelligent surgical scheduling system can improve the scheduling efficiency and quality,improve the utilization of the operation rooms,and improve the collaboration quality and efficiency of the sub-professional nurses.
