Based on database linkage, the objective of this study was to describe the epidemiological profile of notified cases and deaths from the new viral subtype of influenza during the influenza pandemic. Secondary data were used from the SINAN (Information System for Notifiable Diseases) and SIM (Mortality Information System) for the years 2009 and 2010. Linkage identified 5,973 deaths of cases notified as pandemic influenza. Of these, 2,170 (36.33%) had been classified in the SINAN as confirmed pandemic influenza, 215 (3.6%) as due to other infectious agents, and 3,340 (55.92%) as ruled out. After linkage, some cases in the SINAN database that were closed as death from influenza (n = 658) or death from other causes (n = 847) could not be located in the SIM database. Database linkage can improve the surveillance system and monitoring of morbidity and mortality. We recommend strengthening influenza surveillance in Brazil using linkage of Ministry of Health databases.
基于数据库关联，本研究的目的是描述流感大流行期间新病毒亚型流感的报告病例和死亡的流行病学特征。使用了2009年和2010年全国法定传染病信息系统（SINAN）和死亡信息系统（SIM）的二手数据。通过关联确定了5973例被报告为大流行性流感的死亡病例。其中，2170例（36.33%）在SINAN中被分类为确诊的大流行性流感，215例（3.6%）归因于其他传染原，3340例（55.92%）被排除。关联后，SINAN数据库中一些因流感死亡（n = 658）或因其他原因死亡（n = 847）而结案的病例在SIM数据库中无法找到。数据库关联可以改善监测系统以及对发病率和死亡率的监测。我们建议通过卫生部数据库的关联加强巴西的流感监测。
