USA: A new study published in the Journal of American Medical Association (JAMA) shows that extremely preterm infants were more likely to get active therapy in recent years, but care varied by racial and ethnic group.
The choice to begin active life-saving therapy is difficult since birth in the peri-viable period between 22 weeks and 25 weeks and 6 days of gestation is a major cause of infant illness and death. Kartik Venkatesh and colleagues conducted this study in order to determine if the prevalence of active treatment among live-born neonates in the peri-viable period had changed over time and whether active treatment varied by gestational age at birth, race, and ethnicity.

The National Center for Health Statistics natality data for 61 908 singleton live births without clinical abnormalities between 22 weeks 0 days and 25 weeks 6 days in the US were used in this serial cross-sectional descriptive analysis from 2014 to 2020. In this study, the following factors were taken into account: gestational age at birth, year of delivery, and the expectant woman's race and ethnicity, broken down into non-Hispanic Black, non-Hispanic Asian/Pacific Islander, Hispanic/Latina, and non-Hispanic White.
The key outcome was active treatment, which was specified as a composite of surfactant therapy, immediate support breathing at delivery, assisted ventilation lasting more than 6 hours, and/or antibiotic therapy, and was based on whether an attempt was made to treat the neonate. Estimates were made for mean annual percent change (APC), frequencies, and adjusted risk ratios (aRRs).
The key findings of this study were:
1. The final study included 62,000 severely preterm neonates out of the over 27 million live births in the U.S.
2. Medicaid supported 54% of births, and the median mother age was 28.
3. In the research, 37% of the newborns were Black, 24% were Hispanic, and 34% were White. And about 5% of the children were Asian or Pacific Islander.
4. Surfactant therapy, rapid supported breathing at delivery (96%), assisted ventilation for more than 6 hours (60%) and antibiotic therapy (47%) were all administered to roughly 45% of patients who got active treatment.
5. Babies born to Asian or Pacific Islander, Black, or Hispanic parents were less likely to undergo active therapy than babies born to white parents.
6. People of color had a considerably lower likelihood of receiving active therapy for infants born at 23, 24, and 25 weeks gestation.
In conclusion, there were disparities in rates of active treatment by race and ethnicity between 2014 and 2020 in the US, and the frequency of active therapy among neonates delivered alive between 22 weeks 0 days and 25 weeks 6 days rose considerably throughout that time.
