突发公共卫生事件影响范围广且对公众健康危害严重。疾病预防控制中心(CDC)作为中国疾病预防控制与公共卫生技术管理和服务的重要机构,其对突发公共卫生事件的应急反应能力会直接影响应急处置效果,而及时反应可以在第一时间为民众提供有效信息,在最大程度上减少突发事件造成的恐慌,因此,科学地评价CDC部门对突发公共卫生事件的应急反应能力十分重要。本研究以2016年3月18日在山东省发生的非法疫苗事件为例,收集了事件发生后各地级市CDC部门官网上公布的相关信息,并采用时空分析的方法,对中国地市级CDC部门突发公共卫生事件应急反应能力进行了评价。研究方法包括对疫苗事件各地市CDC部门的反应速度和内容的时空可视化分析,以及基于空间扫描统计量方法的CDC部门疫苗事件应急反应的空间聚集性分析,结果显示中国各地CDC部门信息化建设存在地域不均现象;西南地区CDC部门官网对突发公共卫生事件反应明显比其他区域迅速,且具有显著的空间聚集性;山东省和河南省作为疫苗事件中问题疫苗的流通大省,是此次事件的高风险区域,但是其CDC部门的反应速度较慢,对突发公共卫生事件的应急反应能力较弱。
Emergent public health events have a wide range of effect and serious harm to public health. The Centers for Disease Control and Prevention(CDC) is an important institution of disease prevention and control and public health management and technical services in China. Its ability of responding to public health emergency will directly affect the effectiveness of emergency handling and a timely reaction can provide useful information for the public at the first time and reduce the panic caused by this incident to the largest extent. Therefore, it's important to scientifically evaluate the capability of CDC to deal with the public health emergencies. In this study,we took the"Shandong vaccine event"outbreak in March 18, 2016 as an example, collected the relevant information published on the CDC website and used the temporal-spatial analysis to evaluate the capability of CDC in China to deal with the public health emergencies. The data was from the CDC official website of each city which responded to this event. It shows that 73.2% of the total cities has established a CDC official website, of which 69% of the cities have responses. This analysis included the visualization analysis of the speed and the contents of responses and the spatial clustering analysis, using the spatial scan statistics method to detect the spatial cluster of the responded city. The results of this analysis showed that the spatial distribution of the information construction of CDC in China is inequality. Compared with the other regions of China, the CDC department's official websites of cities in southwestern region responded faster on public health emergency, and has a significant spatial clustering in this area. The CDC department of Shandong and Henan provinces which was the huge circulation province of the failing vaccine and the high-risk areas in this vaccine incident, didn't have a timely reaction and the capability of response to the public health emergency is weak.
