PEDRAZA, Dixis Figueroa. Quality of the Information System on Live Births /SINASC: a critical analysis of published studies . Ciênc. saúde coletiva [online]. 2012, vol.17, n.10, pp. 2729-2737. ISSN 1413-8123. http://dx.doi.org/10.1590/S1413-81232012001000021.
The scope of this study was to carry out a review of scientific literature about the quality of data from the Information System on Live Births (SINASC). Studies in the Medline, Lilacs and SciELO databases were then reviewed. The articles were characterized according to journal of publication, location and period of the study, evaluation parameters, methodology and main results. A total of thirteen articles were reviewed. Eight studies analyzed coverage, four assessed completeness and seven evaluated reliability. Coverage higher than 90% was presented in the majority of the studies, indicating its viability for the calculation of indicators. However, the under-reporting of births in SINASC prevailed with variation between 75.8% and 99.5%. The mother's educational level, number of prior childbirths and frequency of prenatal visits were the variables that led to greater inconsistency. For its part, the parity variable was the one that led to greater incompleteness. In conclusion, the development of studies to find new ways of assessing SINASC is highlighted as a privileged strategy for the enhancement of the quality of the system.
