Therefore, we aim to investigate the demographics, mortality, MDR status of gram-negative isolates, and risk factors for MDR gram-negative infections.Methods: We conducted a retrospective single-center study about MDR gram-negative infections in neonates between January 2012-January 2022 at Duzce University Hospital in Turkey. This study evaluates neonates with MDR gram-negative infections' risk factors and clinical features. All analyses were performed using IBM SPSS V23. In addition, univariate analyses and multivariate logistic regression models were studied to determine MDR's risk factors.Results: Of 107 gram-negative bacteria, 41 (38.3%) accounted for Enterobacter, 30 (28%) for Klebsiella pneumonia, and 22 (20.6%) for Escherichia coli. Additionally, 61 (56.5%) were MDR microorganisms. Among the susceptibility tests performed for selected isolates, 41 (77.4%) had resistance to piperacillin, 57 (75%) showed resistance to amoxiclav, and 16 (72.7%) had cefoxitin resistance. In addition, carbapenemase resistance was found in 24 (43.6%) and meropenem resistance in 13 (36.1%). Colistin, aztreonam, and tigecycline resistances were the least frequent. In addition, the following dependent risk factors increased the multidrug resistance risk in gram-negative infections; late-onset sepsis 3.547 fold (p=0.005), use of mechanical ventilation 3.143 fold (p=0.007), blood transfusion 3.587 fold (p=0.013), bronchopulmonary dysplasia 6.702 fold, (p= 0.015) and total parenteral nutrition 5.591 fold (p=0.001), lower gestational age 1.122 (1/0.891) fold (p=0.026), and birth weight 1.001 (1/0.999) fold, (p=0.013). Similarly, antibiotherapy duration was significantly higher in the MDR group than in the non-MDR group.Conclusions: The reported risk factors for MDR in gram-negative neonatal infections are all dependent risk factors. Hence clinicians must be alert to all potential risk factors.en10.18521/ktd.1265336info:eu-repo/semantics/openAccessGram-Negative Bacterial InfectionsNeonatesMultidrug ResistanceArticle1522282351186162WOS:001029516200010Q3
