探讨医院介入导管室手术量季节变动特征，为加强介入导管室管理、合理配置介入医疗资源提供科学依据。

应用时间序列数据季节指数分析法，对我院介入导管室2004年—2018年手术量进行统计，分析手术量随时间的变化趋势。

15年间的手术量总体呈现逐年上升的趋势，并且随季节变化而出现规律性变化。季节指数显示每年7、9月份为最高峰期，1、2月份为低谷期，第三季度达到最高，第一季度最低。

根据介入导管室手术量季节变化规律，采取有针对性的举措，科学组织管理介入手术治疗各项工作，合理分配介入医疗资源，努力实现医疗资源配置最优化和服务患者效用最大化。

To explore the seasonal variation characteristics of the procedural volume in the interventional operation room, so as to provide scientific basis for strengthening the management of interventional operation room and rational allocation of interventional medical resources.

The procedural volume of interventional operation room in our hospital from 2004 to 2018 was analyzed by seasonal index analysis of time series data, and the changing trend of the operative volume with time was investigated.

The procedural volume in the past 15 years showed an increasing trend year by year and changed regularly with seasonal changes. The seasonal index showed the peak in July and September, the trough in January and February, the highest in the third quarter and the lowest in the first quarter.

According to the seasonal variation of procedural volume in the interventional operation room of our hospital, targeted measures should be taken to scientifically organize and manage the interventional surgical treatment, rationally allocate interventional medical resources, and strive to achieve the optimal allocation of medical resources and maximize the effectiveness of serving patients.
