由于记录连锁错误可能会使疾病发生和关联的测量产生偏差，因此评估其准确性非常重要。本研究的目的是评估的准确性，多通概率记录链接策略，以确定死亡的人报告给巴西艾滋病监测数据库。一个艾滋病毒/艾滋病国家监测数据库（N = 559 442）与巴西死亡率数据库中登记的总共6 444 822例死亡（所有原因）相关联。为了估计准确性的标准措施，我们选择了2002年至2005年在监测数据库中登记的所有艾滋病病例（N = 19，750）和2006年已知的38，675例存活病例。连锁策略的敏感性为87.6%（95%CI：87.1-88.2），特异性为99.6%（95%CI：99.6-99.7），阳性预测值为99.2%（95%CI：99.1-99.3）。我们观察到一个小的变化，根据一些假定的预测死亡率的有效性措施。我们的研究结果表明，即使是大型和异构的数据库可以连接到一个令人满意的精度。
Since record linkage errors can bias measures of disease occurrence and association, it is important to assess their accuracy. The aim of this study is to assess the accuracy of a multiple pass probabilistic record linkage strategy to identify deaths among persons reported to the Brazilian AIDS surveillance database. An HIV/AIDS national surveillance database (N = 559,442) was linked to a total of 6,444,822 deaths registered (all causes) in the Brazilian mortality database. To estimate standard measures of accuracy, we selected all AIDS cases with a date of death registered in the surveillance database from 2002 to 2005 (N = 19,750) and 38,675 cases known to be alive in 2006. The linkage strategy presented a sensitivity of 87.6% (95% CI: 87.1-88.2), a specificity of 99.6% (95% CI: 99.6-99.7), and a positive predictive value of 99.2% (95% CI: 99.1-99.3). We observed a small variation in the validity measures according to some putative predictors of mortality. Our findings suggest that even large and heterogeneous databases can be linked with a satisfactory accuracy.
