Changes in perceptions of antibiotic stewardship among neonatal intensive care unit providers over the course of a learning collaborative: a prospective, multisite, mixed-methods evaluation.
The purpose of this study was to assess clinician perceptions towards the value and implementation of antibiotic stewardship (AS) in neonatal intensive care units (NICU). The researchers conducted a mixed-methods study of AS perceptions utilizing surveys and interviews in 30 California NICUs before and after a multicenter collaborative (Optimizing Antibiotic Use in California NICUs [OASCN]). The study found that pre-OASCN, 24% of respondents believed there was "a lot of" or "some" inappropriate prescribing, often driven by fear of a bad outcome or hesitation to change existing practices. Clinicians reported statistically significant increases in AS importance, perceived AS activity, and more openness to change after OASCN.

Antibiotic use among infants admitted to neonatal intensive care units.
The purpose of this cross-sectional study was to examine antibiotic exposure, days of therapy, types of antibiotics, and changes in use patterns among newborns in neonatal intensive care units (NICUs) across the U.S. Data for almost 1.4 million infants were taken from the Premier Healthcare Database. The most common antibiotics prescribed during the study period were ampicillin, gentamicin, vancomycin, and cefotaxime. Antibiotic use declined substantially over time, primarily because of reductions in ampicillin and gentamicin. The authors noted that these findings probably reflect the penetration of national calls for neonatal antibiotic stewardship efforts and refined early-onset infection risk-assessment strategies; shortage and subsequent discontinuation of cefotaxime may have played a role in the sharp decline in its use and the related increase in ceftazidime use.

Antibiotic spectrum index: a new tool comparing antibiotic use in three NICUs.
This study looked at a new tool called the antibiotic spectrum index (ASI) which quantifies antibiotic exposure by relative antimicrobial activity, adding information to exposure measured by days of therapy (DOT). This index was tested with very low-birth-weight infants (VLBW, <1500g) in 3 level-4 NICUs for 2 years at 2 sites and for 1 year at a third site. The authors calculated the ASI per antibiotic days and DOT per patient days for all admitted VLBW infants <32 weeks gestational age. The site with the highest DOT per patient days was found to have the lowest ASI per antibiotic days and the site with the highest mortality and infection rates were found to have the highest ASI per antibiotic days. Antibiotic utilization varied by center.

Antibiotic susceptibility of Escherichia coli among infants admitted to neonatal intensive care units across the US From 2009 to 2017.
Investigators assessed the epidemiologic characteristics and antibiotic susceptibility patterns of E coli in infants admitted to neonatal intensive care units in the US over time. Using the Premier Health Database, they found nonsusceptibility to commonly administered antibiotics in substantial proportions of neonatal E coli isolates, with no significant change from 2009 to 2017. They suggested that their findings may inform empirical antibiotic choices for newborn infants.
