Outcomes following a comprehensive versus a selective approach for infants born at 22 weeks of gestation.

Backes CH, et al. J Perinatol. 2019.


OBJECTIVE: To examine outcomes at two institutions with different approaches to care among infants born at 22 weeks of gestation.

STUDY DESIGN: Retrospective, cohort study (2006-2015). Enrollment was limited to mother-infant dyads at 22 weeks of gestation. Proactive care was defined as provision of antenatal corticosteroids and neonatal resuscitation and intensive care. One center (Uppsala, Sweden; UUCH) provided proactive care to all mother-infant dyads (comprehensive center); the other center (Nationwide Children's Hospital, USA; NCH) initiated or withheld treatment based on physician and family preferences (selective center). Differences in outcomes between the two centers were evaluated.

RESULT: Among 112 live-born infants at 22 weeks of gestation, those treated at UUCH had in-hospital survival rates higher than those at NCH (21/40, 53% vs. 6/72, 8%; P < 0.01). Among the subgroup of infants receiving proactive care (UUCH: 40/40, 100%; NCH: 16/72, 22%) survival was higher at UUCH than at NCH (21/40, 53% vs. 3/16, 19%; P < 0.05).

CONCLUSION: Even when mother-infant dyads were provided proactive care at NCH (selective center), survival was lower than infants provided proactive care at UUCH (comprehensive center). Differences between the approaches to care at the two centers at 22 weeks of gestation merits further investigation.
