Outcomes of preterm infants conceived with in vitro fertilization.

Objectives: To determine if there is increased risk of prematurity-related complications for in vitro fertilization (IVF)-conceived preterm infants compared to matched controls.

Study Design: Cohort study of 23-34 weeks' preterm infants from 329 US NICUs discharged from 2009 to 2016. Each IVF patient was matched to three controls.

Implementation of an Automatic Stop Order and Initial Antibiotic Exposure in Very Low Birth Weight Infants.

 To evaluate if an antibiotic automatic stop order (ASO) changed early antibiotic exposure (use in the first 7 days of life) or clinical outcomes in very low birth weight (VLBW) infants.  We compared birth characteristics, early antibiotic exposure, morbidity, and mortality data in VLBW infants (with birth weight <= 1500 g) born 2 years before (pre-ASO group,  = 313) to infants born in the 2 years after (post-ASO,  = 361) implementation of an ASO guideline. Early antibiotic exposure was quantified by days of therapy (DOT) and antibiotic use > 48 hours.
