Congenital malformations (CM) are significant cause of morbidity and mortality, accounting for 9% of the surgical burden of disease, contributing to the disability of 150 million children worldwide, primarily low-income children, and being both a cause and a result of low socioeconomic status. Recording the occurrence of congenital defects allows us to identify populations at greater risk, implementing prevention programs and estimating service needs. It also allows us to monitor changes in occurrence, identifying and investigating clusters.

We present a comparison between official data available in DATASUS for the state of Acre, Amazonia-Brazil, and data recorded on hospital admissions between 2017 and 2022. All newborns admitted to or diagnosed with the following CM during their stay at the region's referral maternity hospital were included: Anorectal anomalies, Hirschsprung's disease, esophageal atresia, intestinal atresia, gastroschisis, omphalocele, and diaphragmatic hernia, which collectively account for up to 40% of emergency neonatal surgeries. This study was approved by Plataforma Brasil, CAAE 49973421.0.0000.5010.

Alarming underreporting of congenital anomalies, with all records being less than 50%. Findings regarding the percentage of notifications to DATASUS: anorectal anomaly (40%), Hirschsprung's disease (11%), esophageal atresia (27%), intestinal atresia (41%), gastroschisis (42%), omphalocele (28%), and diaphragmatic hernia (27%). It is observed that even congenital anomalies that are easily diagnosed by physical examination are underreported.

A policy aimed at improving the quality of this information is necessary, perhaps with compulsory notification at the time of hospital discharge, rather than upon admission, to include those diagnosed during the hospital period.
