Abstract

Objective: to describe the frequency of underreporting of unfavorable outcomes of congenital syphilis in the state of Sao Paulo, Brazil, 2007-2018. Methods: this was a descriptive study of cases of abortion, fetal and non-fetal deaths due to congenital syphilis reported on the Notifiable Health Conditions Information System (Sistema de Informacao de Agravos de Notificacao -SINAN), and those of congenital syphilis registered in any line in the Death Certificate, on the Mortality Information System (Sistema de Informacoes sobre Mortalidade -SIM), by means of probabilistic and deterministic linkage. Results: of the 27,713 cases of congenital syphilis reported, 1,320 progressed to death (871 fetal deaths, 449 infant deaths) and were matched to the SIM; 355 deaths (259 fetal deaths, 96 infant deaths) were not included on SINAN; there was an increase in unfavorable outcomes,11.4% for infant deaths due to congenital syphilis, 3.0% for fetal deaths and 1.9% for abortions. Conclusion: the use of different relationship techniques proved to be adequate to identify the frequency of underreporting of unfavorable outcomes of congenital syphilis in the state of Sao Paulo.
