ABSTRACT

The goal was to evaluate the impact of statewide coordinated changes in perinatal support and retrieval services on the outcomes of extremely premature births occurring outside perinatal centers in the state of New South Wales, Australia.
The intervention included additional, network-coordinated, perinatal telephone advice to optimize in utero transfers and centralization of the neonatal retrieval system, with preferential admission of retrieved infants (outborn infants) to perinatal centers instead of freestanding pediatric hospitals, from the middle of 1995. Population birth and NICU admission cohorts of infants of 23 to 28 weeks of gestation were studied. Outcomes of epoch 1 (1992 to the middle of 1995; 1778 births and 1100 NICU admissions) were compared with those of epoch 2 (1997-2002; 3099 births and 2100 NICU admissions), after an 18-month washout period.
There were 25% fewer nontertiary hospital live births (19.7% vs 14.9%) and more prenatal steroid use. Despite an 11.4% average annual increase in NICU admissions between the 2 epochs, fewer infants were outborn (12.0% vs 9.3%) and outborn mortality rates decreased significantly (39.4% vs 25.1%), particularly for those between 27 and 28 weeks of gestation. The overall improvement was equivalent to 1 extra survivor per 16 New South Wales births. There were also significantly fewer serious outcome morbidities in outborn infants during epoch 2, over the improvements in inborn infants.
Statewide coordinated strategies in reducing nontertiary hospital births and optimizing transport of outborn infants to perinatal centers have improved considerably the outcomes of extremely premature infants. These findings have vital implications for health outcomes and resource planning.

    ABSTRACT: Rural and remote residents in Australia have long experienced unfavourable health outcomes compared to their urban counterparts. To study neurodevelopmental outcome at 2-3years of age, corrected for prematurity of extremely preterm infants admitted to a regional neonatal Australian network from rural and urban regions (based on usual location of maternal residence). A multicenter population-based cohort study in which surviving urban and rural infants <29weeks of gestation born between 1998 and 2004 underwent neurodevelopmental assessment at 2-3years of age, corrected for prematurity by a developmental assessment team. Moderate/severe functional disability was defined as developmental delay (GQ or MDI>2 SD below the mean), cerebral palsy (aided for walking), sensorineural or conductive deafness (requiring amplification), and bilateral blindness (visual acuity <6/60 in the better eye). Of the 1970 infants alive at 2-3years of age, 268 (63.8%) rural and 1205 (77.7%) urban infants were evaluated. Infants lost to follow-up were of slightly higher gestational age and birth weight. Both rural and urban assessed groups were comparable in gestation and birth weight percentile. In comparison to their urban counterparts, the rural group had more outborn infants (19.8% vs. 4.6%, p<0.001). They, however, did not have an increased risk of moderate/severe functional disability (OR 0.77, 95% CI 0.52-1.23, p=0.176). This finding was not significantly altered by limiting the analysis to different gestational ages. Extremely premature surviving young children from rural areas of residence do not seem to have an increased risk for moderate/severe functional disability. Copyright © 2015 Elsevier Ireland Ltd.

    • "Other studies have concluded that an important factor associated with outcome is the need for transport from the delivery hospital to a higher level NICU7891011121314. Indeed, it has been found in some studies that the rates of severe neonatal morbidities were lower in those premature infants born after maternal transport than in premature infants transported after birth[15,16]. Thus, both delivery hospital and transport have been implicated in impacting the outcomes of premature infants following neonatal intensive care. Nationwide Children's Hospital (NCH) is the only tertiary care NICU (Level IIIc) in Central Ohio, but does not provide a delivery service. "

    ABSTRACT: Objective: The outcome of premature infants is negatively impacted by transport, and in Central Ohio every effort is made to transport the mother prior to preterm delivery. Our neonatal intensive care unit is an all referral unit, thus all babies are transported and the referral hospitals include those without neonatology coverage, and those with neonatology coverage. We tested the hypothesis that the outcomes of extremely premature infants (<27 weeks gestational age) admitted to our NICU would be better when the infant was referred from a hospital with neonatology coverage. Patients and methods: We collected data from 227 patients admitted from December, 2004 to August, 2008; 192 patients were from hospitals with neonatology coverage. Results: The survival rate was greater for those babies referred from hospitals with neonatology coverage than in those referred from hospitals without neonatology coverage (82% vs. 60%, p = 0.007), as was the combined outcome of survival without Grade 3/4 IVH (68% vs. 43%, p < 0.01). When limited to only those patients admitted at <3 days of life, survival was better for infants referred from hospitals with neonatology coverage than those referred from hospitals without it (77% vs. 63%; p < 0.05). Conclusion: These results suggest that for infants born at <27 weeks admitted to an all referral unit delivery in a hospital with neonatology coverage leads to better survival.
