Abstract

Objective

To evaluate the completeness, consistency and duplicity of records of child sexual abuse on the Notifiable Health Conditions Information System (SINAN) in Santa Catarina, Brazil, between 2009 and 2019.

Methods

This was a descriptive and analytical cross-sectional study aimed to assess the quality of SINAN data regarding completeness, consistency and non-duplicity.

Results

3,489 cases of violence were reported, with a 662.5% increase in the number of notifications in the period studied, with the increase in the number of referral centers for the care of people in situations of sexual violence in the state, explaining 46.7% of the variation in the number of cases, between the years studied. Consistency was excellent in 90.0% of the records; and completeness ranged between excellent and good in 92.3% of them. There was an increased trend in completeness for 14 variables in the period. There were no duplicate records.

Conclusion

Data from the sexual violence against children surveillance system were considered adequate regarding the questions that were assessed in the study.

Study contributions
Main results	There was a 662.5% increase in the number of notifications of sexual violence against children in Santa Catarina between 2009-2019. There were no duplicate records, consistency was excellent in 90.0% of the records, and completeness was considered good to excellent in 92.3% of them.
Implications for services	Data quality regarding the items evaluated, when quite adequate for making inferences, helps services and managers have a real notion of the information measured and subsidize the actions aimed to cope with the health condition.
Perspectives	This study aims to collaborate in order to corroborate the potential of SINAN as a surveillance tool for sexual violence against children, contributing to planning and evaluating public policies.
