Predictors of Stress Exposure in Hospitalized Preterm Infants

Area of Science:

• Neonatalogy
• Pediatric Critical Care
• Perinatal Health

Background:

• Neonatal intensive care unit (NICU) stress is linked to adverse outcomes in preterm infants.
• Predictors of NICU stress exposure in this vulnerable population remain unidentified.

Purpose of the Study:

• To characterize the types and frequency of NICU stressors in preterm infants within the first two weeks of life.
• To identify demographic, perinatal, and institutional factors associated with NICU stress exposure.

Main Methods:

• Secondary analysis of data from 60 very preterm infants (28-31 weeks gestational age).
• Stress exposure quantified as the number of invasive procedures extracted from electronic health records.
• Linear regression models analyzed associations between invasive procedures and predictor variables.

Main Results:

• Preterm infants experienced an average of 98 invasive procedures in the first two weeks.
• Nasal/oral suctioning and skin-breaking procedures were most common.
• Significant differences in procedure counts were observed based on maternal race and NICU.

Conclusions:

• NICU stress exposure in preterm infants is influenced by maternal race and the specific NICU.
• Findings suggest potential racial disparities in the treatment of diverse infants.
• Further research is essential to understand these differences and standardize neonatal care practices.
