Abstract: OBJECTIVES: To characterize the resistance pattern and possible risk factors for staphylococcal infections in newborns at the Clinical Hospital, Goias Federal University (HCUFG). MATERIAL AND METHOD: Retrospective cohort study. Data collection was carried out between January and August of 2021, through the analysis of medical records available at the Medical Service and Health Information (SAMIS) of HC UFG. The sample consisted of children in the neonatal period, who were admitted to the ward or neonatal intensive care unit of the HC UFG, from January 2017 to December 2020, with a positive culture test for Staphylococcus sp. For the analysis of each patient, was taken into account the identification and sociodemographic profile; obstetric history and birth conditions; risk factors for neonatal infections and the clinical and microbiological characteristics of the infection, being these data recorded in a specific questionnaire. Data were analyzed using descriptive statistics and comparative analysis. RESULTS: In total, 84 medical records were analyzed, with no relatively significant difference between genders. Among the sites of involvement, the most frequent was the bloodstream (32.9%), followed by infection in catheters/devices (23.2%). As for the isolated microorganism, 27.4% corresponded to infection by Staphylococcus aureus and 72.6% by Staphylococcus sp. negative coagulases. As for the pattern of resistance to methicillin, in cultures positive for Staphylococcus aureus, 56.5% were resistant to methicillin, and in isolates of Staphylococcus sp. negative coagulase, 88.3% were resistant to the aforementioned antimicrobial. Premature rupture of membranes was the main risk factor related to staphylococcal infection (p=0.01). CONCLUSION: The finding of predominance of neonatal infections by coagulase-negative staphylococcal species corroborates to current studies found in the literature. Apart from premature rupture of membranes, no other risk factor was statistically significant. Furthermore, data regarding the resistance pattern confirmed the predominance of Staphylococcus sp. resistant to methicillin in the neonatal sample, both in the aureus species and in the negative coagulase, serving as a parameter in clinical decision-making.
