Abstract
As broader spectrum antibiotics have been associated with adverse effects, our study evaluated whether the frequency of culture-positive late-onset sepsis (LOS) and multidrug resistant (MDR) infections were increased with the use of ceftazidime as compared with cefotaxime in the neonatal intensive care unit (NICU). This was a multihospital, retrospective chart review of patients who received at least 24 hours of ceftazidime or cefotaxime in the NICU between December 1, 2012 and August 31, 2021. Patients were excluded from analysis if they expired during the admission, had an incomplete history, positive cultures for an MDR infection prior to receiving either antibiotic, or received the alternate antibiotic within the same treatment course. A total of 334 patients were included for analysis (ceftazidime, n = 147; cefotaxime, n = 187). The average birth weight was lower in the ceftazidime cohort compared with the cefotaxime cohort [1.46 kg (95% CI, 1.29-1.63 kg) versus 1.93 kg (95% CI, 1.75-2.11 kg), p = 0.0002] with a corresponding lower gestational age [28.9 weeks (95% CI, 28.0-29.9 weeks) versus 31.7 weeks (95% CI, 30.8-32.6 weeks), p = 0.0001]. Adjusting for baseline differences showed a protective effect for ceftazidime (OR = 0.32; 95% CI, 0.16-0.62; p = 0.0009). There was no statistically significant difference in the frequency of MDR infections between the cohorts (OR = 0.25; 95% CI, 0.053-1.14; p = 0.07), however this study was underpowered to detect the difference noted. Ceftazidime appears to be a safe and effective alternative treatment option compared with cefotaxime in the NICU with no increase in the risk of culture-positive LOS or MDR infections.
