The objective of this article is to assess coverage and reliability of data from the Information System on Live Births in the City of Rio de Janeiro, based on an analysis of live birth certificates issued by the various hospitals and compared to information from the "Study on Neonatal and Perinatal Morbidity and Mortality and Care in the City of Rio de Janeiro". A total of 9,608 interviews with post-partum women were paired case-by-case with the respective birth certificates. The statistical analysis consisted of calculating the Kappa index adjusted to the prevalence of categorical variables and the intra-class correlation coefficient for continuous variables, with a 95% significance level. The study showed excellent coverage (96.5%) for hospital births in the City of Rio de Janeiro during the period studied. The variables presenting the highest concordance levels (over 0.90) were the infant's sex, birth weight, mother's age, type of delivery, and type of pregnancy. The variables marital status, mother's schooling, and number of prenatal visits showed lower reliability indices (Kappa < 0.70). The article discusses the importance of data quality in the Information System on Live Births (SINASC) and the system's use as a tool to help define maternal and child health policies.
本文的目的是基于对里约热内卢市各医院出具的出生证明的分析，并与“里约热内卢市新生儿和围产期发病率、死亡率及护理研究”中的信息进行比较，评估里约热内卢市活产信息系统数据的覆盖范围和可靠性。对9608名产后妇女进行了访谈，并将其与各自的出生证明逐例配对。统计分析包括计算针对分类变量患病率调整的卡帕指数以及连续变量的组内相关系数，显著性水平为95%。研究表明，在所研究期间，里约热内卢市医院分娩的覆盖率极高（96.5%）。一致性水平最高（超过0.90）的变量是婴儿性别、出生体重、母亲年龄、分娩类型和妊娠类型。婚姻状况、母亲受教育程度和产前检查次数等变量的可靠性指数较低（卡帕<0.70）。本文讨论了活产信息系统（SINASC）中数据质量的重要性以及该系统作为帮助制定母婴健康政策工具的用途。
