To evaluate the quality of information on gestational syphilis (GS) and congenital syphilis (CS) on the Sistema de Informação de Agravos de Notificação (SINAN-Syphilis Brazil - Notifiable Diseases Information System) by compiling and validating completeness indicators between 2007 and 2018.
Overall, care, and socioeconomic completeness scores were compiled based on selected variables, by using ad hoc weights assigned by experts. The completeness scores were analysed, considering the region and area of residence, the pregnant woman's race/colour, and the year of case notification. Pearson's correlation coefficients were used to validate the scores obtained by the weighted average method, compared with the values obtained by principal component analysis (PCA).
Most selected variables presented a good or excellent degree of completeness for GS and CS, except for clinical classification, pregnant woman's level of education, partner's treatment, and child's race/colour, which were classified as poor or very poor. The overall (89.93% versus 89.69%) and socioeconomic (88.71% versus 88.24%) completeness scores for GS and CS, respectively, were classified as regular, whereas the care score (GS-90.88%, and CS-90.72%) was good, despite improvements over time. Differences in the overall, care and socioeconomic completeness scores according to region, area of residence, and ethnic-racial groups were reported for syphilis notifications. The completeness scores estimated by the weighted average method and PCA showed a strong linear correlation (> 0.90).
The completeness of GS and CS notifications has been improving in recent years, highlighting the variables that form the care score, compared with the socioeconomic scores, despite differences between regions, area of residence, and ethnic-racial groups. The weighted average was a viable methodological alternative easily operationalised to estimate data completeness scores, allowing routine monitoring of the completeness of gestational and congenital syphilis records.
通过编制和验证 2007 年至 2018 年之间的完整性指标，评估 Sistema de Informação de Agravos de Notificação（SINAN-Syphilis Brazil-传染病信息系统）中关于妊娠梅毒（GS）和先天性梅毒（CS）的信息质量。
根据选择的变量，采用专家分配的特定权重，综合了总体、护理和社会经济完整性评分。分析了完整性评分，考虑了地区和居住地、孕妇的种族/肤色以及病例通知年份。使用 Pearson 相关系数验证加权平均值法获得的评分与主成分分析（PCA）获得的值之间的相关性。
除了临床分类、孕妇的教育程度、伴侣的治疗和孩子的种族/肤色外，大多数选择的变量对于 GS 和 CS 都具有良好或优秀的完整性程度，这些变量被归类为较差或非常差。GS 和 CS 的总体（89.93%与 89.69%）和社会经济（88.71%与 88.24%）完整性评分分别被归类为常规，而护理评分（GS-90.88%，CS-90.72%）则较好，尽管随着时间的推移有所改善。梅毒通知的地区、居住地和族裔群体之间存在总体、护理和社会经济完整性评分的差异。加权平均值法和 PCA 估计的完整性评分显示出很强的线性相关性（>0.90）。
近年来，GS 和 CS 通知的完整性一直在提高，与社会经济评分相比，突出了构成护理评分的变量，尽管地区、居住地和族裔群体之间存在差异。加权平均值是一种可行的方法学替代方案，易于操作以估计数据完整性评分，允许对妊娠和先天性梅毒记录的完整性进行常规监测。
