目的评价中国疾病预防控制信息系统在水痘暴发疫情监测报告中的效能。方法通过水痘专报系统收集2005-2010年闸北区报告的水痘暴发疫情病例,分析这些病例在中国疾病预防控制信息系统中的网络直报率、重要项目信息报告完整性和监测敏感性。结果上海市闸北区2005-2010年水痘专报系统共报告112起902例病例,网络直报428例(47.45%),其中71例(7.87%)为区疾病预防控制中心调查核实后补报,只有357例(39.58%)为医疗机构报告,网络直报病例与专报病例数呈正相关(r=0.951,P=0.004)。网络直报率呈逐年上升趋势(χ2趋势=20.178,P=0.000)。医疗机构报告病例中73例(20.45%)重要项目信息不完整,三级医疗机构报告信息完整性(χ2=30.913,P=0.000)和发病4 d内报告率(χ2=7.364,P=0.025)均低于一、二级医疗机构。结论提高中国疾病预防控制信息系统对水痘疫情报病效能,将有助于控制水痘暴发疫情。
Objective To evaluate the efficacy of China’s disease prevention and control information system in the surveillance report of chickenpox outbreak. Methods The cases of chickenpox outbreaks reported in Zhabei District from 2005 to 2010 were collected through the chickenpox reporting system. The direct reporting rate of these cases in China’s disease prevention and control information system, the integrity and monitoring sensitivity of important project information were analyzed. Results A total of 902 cases of 112 cases were reported from Zhabei District in Shanghai in 2005-2010. There were 428 cases (47.45%) of them directly reported by the network, of which 71 cases (7.87%) were reported to the CDC for investigation and verification. Only 357 cases (39.58%) reported to the medical institutions that the number of cases reported by internet was positively correlated with the reported number of reported cases (r = 0.951, P = 0.004). The rate of internet direct reporting increased year by year (χ2 trend = 20.178, P = 0.000). 73 cases (20.45%) of the reported cases in medical institutions had incomplete information, the third-level medical institutions reported completeness of information (χ2 = 30.913, P = 0.000) and reporting rate within 4 days of onset (χ2 = 7.364, P = 0.025) Are lower than one or two medical institutions. Conclusion Increasing the efficacy of Chinese disease control and prevention information system in reporting disease of chicken pox will help to control the outbreak of chicken pox.
