RESUMEN
BACKGROUND: Patient safety culture is influenced by factors such as professional category, experience, and age. Understanding these factors can inform initiatives to improve safety. PURPOSE: To evaluate the relationship between sociodemographic and occupational characteristics on health professionals' perception of patient safety culture. METHODS: A cross-sectional study involving 514 health care professionals from Brazilian neonatal intensive care units was conducted using the Hospital Survey on Patient Safety Culture. RESULTS: Several sociodemographic and occupational characteristics were associated with higher perceptions of safety culture, including older age and having a higher level of education. CONCLUSION: Sociodemographic and occupational factors may influence the safety culture in neonatal intensive care units and should be considered when developing and implementing strategies to improve safety.
