A quality improvement initiative to reduce antibiotic use in transient tachypnea of the newborn.

OBJECTIVE

Evidence suggests that antibiotics are unnecessary in infants with transient tachypnea of the newborn (TTN) that are low-risk for early-onset sepsis. The aim was to reduce ampicillin and gentamicin days of therapy (DOT) in infants with suspected TTN by 10% within 12 months.

STUDY

DESIGN

We used the Model for Improvement to test interventions from August 2019 to September 2021 to decrease antibiotic utilization in low-risk infants with TTN. Interventions included the creation of an evidence-based clinical pathway, admission huddles, and prescriber audit and feedback.

RESULTS

We reduced ampicillin and gentamicin use by 26% and 23%, respectively. In 123 infants with suspected TTN, we sequentially decreased starting antibiotics in this group from 71% to 41%, 13% and 0%. There were no cases of missed bacteremia.

CONCLUSION

Creation of a multidisciplinary antimicrobial stewardship QI team and subsequent interventions were successful in safely reducing antibiotic use in infants with TTN.
