Association of Resident Duty Hour Restrictions, Level of Trainee, and Number of Available Residents with Mortality in the Neonatal Intensive Care Unit

Association of timing of birth with mortality among preterm infants born in Canada

OBJECTIVE

To assess the association between time of birth and mortality among preterm infants.

STUDY DESIGN

Population-based study of infants born 22-36 weeks gestation (GA) in Canada from 2010 to 2015 (n = 173 789). Multivariable logistic regression models assessed associations between timing of birth and mortality.

RESULT

Among infants 22-27 weeks GA, evening birth was associated with higher mortality than daytime birth (adjusted odds ratio [AOR] 1.14, 95% CI 1.01-1.29). Among infants 28-32 weeks GA and 33-36 weeks GA, night birth was associated with lower mortality than daytime birth (AOR 0.75, 95% CI 0.59-0.95; AOR 0.78, 95% CI 0.62-0.99, respectively). Sensitivity analysis excluding infants with major congenital anomaly revealed that associations between hour of birth and mortality among infants born 28-32 and 33-36 weeks GA decreased or were not statistically significant.

CONCLUSION

Higher mortality among extremely preterm infants during off-peak hours may suggest variations in available resources based on time of day.

Improving the Resident Educational Experience in a Level IV Neonatal/Infant Intensive Care Unit

Supplemental Digital Content is available in the text.

The neonatal/infant intensive care unit (N/IICU) at the Children’s Hospital of Philadelphia is a 98-bed, level IV unit through which second-year pediatric residents rotate monthly. We developed a quality improvement project to improve the resident educational experience using goal setting. Primary objectives were to increase resident educational goal identification to 65% and goal achievement to 85% by June 2017. Secondary objectives were to (1) increase in-person feedback from fellows and/or attendings to 90% by June 2017 and (2) sustain improvements through June 2018.
