Preterm and Term Infants Evaluated for Sepsis: Differences in Management and Clinical Outcomes.

To describe differences in practice patterns and outcomes of young preterm versus age-matched term infants evaluated for sepsis, because evaluation and management of this group are not well defined.We conducted a retrospective single-center study at an academic, freestanding children's hospital of previously healthy preterm and term infants aged 0 to 60 days, who presented for initial evaluation of fever and/or hypothermia from 2014 to 2019. We classified infants by gestational age as preterm (32-36 6/7 weeks) and term (37-42 weeks) and compared diagnostic evaluation, management, and clinical outcomes.Out of 363 preterm infants evaluated for sepsis, 336 met inclusion criteria; within the same study period, 2331 term infants were evaluated for sepsis, of which 600 were randomly selected and 554 were included. Clinicians performed inflammatory marker testing and chest x-rays more frequently in preterm infants 31% vs 25% (P = .034) and 50% vs 32% (P < .001), respectively. Preterm infants had a higher rate of bacteremia 5.9% vs 2.5% (P = .035), were hospitalized more frequently 72% vs 63% (P = .006), and required ICU level of care more often 32% vs 5% (P < .001) than term infants. They had lower rates of viral infections 33% vs 42% (P = .015) and no significant increased return visits. Febrile preterm and term infants, and older hypothermic preterm infants had relatively higher rates of serious bacterial infections. Hypothermic preterm infants had the longest hospitalizations.Preterm infants had increased rates of bacteremia and required higher level of care compared with age-matched term infants, likely reflecting their increased risk for sepsis and other concomitant morbidities associated with preterm birth.Copyright © 2023 by the American Academy of Pediatrics.
