Information system on live births: a quality analysis based on literature

Abstract

Introduction

The evaluation of SINASC is essential to verify its usefulness related to scientific research and health policies.

Objective

To review the published literature between 2010 and 2018 on data quality of SINASC.

Method

A systematic review of the literature on studies evaluating SINASC using quality indicators (completeness, reliability, coverage) was carried out.

Results

In the reviewed studies, the number of dead children, maternal occupation, gestational age, and race/color were the variables with more frequencies of incompleteness. Maternal education level, gestational age, number of prenatal consultations, and number of dead children stood out with low concordance. In coverage, it was possible to systematize the underreporting of births in the municipal studies. In the evaluation of Life Births, gestational age was the only variable with poor completeness; the lowest concordances were found for gestational age and the number of dead children.

Conclusion

It should be noted that: i. the coverage of SINASC is not homogeneously distributed in the Brazilian microregions and municipalities, ii. the information on the number of dead children and the gestational age present low filling quality in SINASC.
