The aim of the study was to analyze the underreporting of deaths from tuberculosis (TB) in Brazil, as well as to assess the impact these cases would cause in the reporting rate and proportion of TB deaths in 2006. We analyzed the deaths recorded in the Mortality Information System (SIM) in 2006 and all reports of TB in Brazil during the 2001 to 2006 period. The variables used for the relationship were: report number, city and State of residence, patient name, date and year of birth, sex, mother's name and address. Six blocking steps were performed. Scores above 12.4 were considered pairs, and those below 9.7, doubtful pairs. After each step, we performed a manual review of doubtful pairs. The Reportable Disease Information System (Sinan) had 547,589 records. The SIM had 6,924 records, 39.3% (n = 2,727) of which were not found in Sinan during the period evaluated. We observed that 64.5% (2,707) of deaths were reported in 2006 and after analyzing the proportion of deaths underreported by region and federal units, we found that the highest percentage was in the Northern region, followed by the Southeast and Northeast. The addition of deaths that had not been reported to the Sinan database increased the reporting rate 3.7%. Regarding the proportion of deaths due to TB, such inclusion was responsible for a 60.7% increase in this indicator. The relationship between both databases seems to be an important strategy for improving the quality of the TB surveillance system.
该研究的目的是分析巴西结核病（TB）死亡报告不足的情况，以及评估这些病例对2006年结核病死亡报告率和比例的影响。我们分析了2006年死亡信息系统（SIM）中记录的死亡情况以及巴西在2001年至2006年期间所有的结核病报告。用于关联的变量有：报告编号、居住城市和州、患者姓名、出生日期和年份、性别、母亲姓名和地址。进行了六个阻断步骤。得分高于12.4的被视为配对，低于9.7的为可疑配对。在每个步骤之后，我们对可疑配对进行人工审核。法定传染病信息系统（Sinan）有547,589条记录。SIM有6,924条记录，其中39.3%（n = 2,727）在评估期间未在Sinan中找到。我们观察到2006年报告了64.5%（2,707例）的死亡病例，在按地区和联邦单位分析未报告死亡病例的比例后，我们发现最高比例出现在北部地区，其次是东南部和东北部。将未报告给Sinan数据库的死亡病例纳入后，报告率提高了3.7%。关于结核病死亡病例的比例，这种纳入使该指标增加了60.7%。两个数据库之间的关联似乎是提高结核病监测系统质量的一项重要策略。
