Outcomes of inborn and transported extremely premature very-low-birthweight infants in Hawai'i.

BACKGROUND

Delivery of premature infants outside tertiary care centers is not always preventable. The aim of this study was to compare rates of survival and common morbidities in extremely premature babies transported to a level III facility versus those born at the level III center.

METHODS

Retrospective chart review was performed on all neonates born at ≤ 28 weeks of gestation with birthweight ≤ 1500 g who were admitted to the Newborn Intensive Care Unit at Kapi'olani Medical Center for Women and Children (KMCWC) between 1 January 2000 and 31 December 2005. Infants were divided into two groups, those born at KMCWC (Inborn) and those born at level I institutions and subsequently transported (Transport) to KMCWC.

RESULTS

A total of 394 neonates met the study criteria; 349 were inborn while 45 were transported. Survival rates were identical for both groups. However, the Transport group survivors displayed a significantly longer mean length of stay and higher rate of severe retinopathy of prematurity than those in the Inborn group (P ≤ 0.01).

CONCLUSION

Identical rates of survival in both groups suggest that community medical professionals are providing satisfactory care to stabilize critical neonates without reducing their chances of survival. However, increased length of stay and higher rate of retinopathy of prematurity in the Transport group suggest that differences in medical management during the first few hours of life may adversely affect outcomes.
