Intervention Results:

Perceived risk, age, education, and prenatal care characteristics of women affected the likelihood of use of the NICU. The perceived availability of local expertise was associated with a lower likelihood that preterm infants would deliver at the NICU. ANGELS did not increase the overall use of NICU, but it did shift some deliveries to the academic setting.

Intervention Results:

The number of maternal transports to the level III hospital increased from 65 before intervention to 280 after intervention. This was accompanied by a corresponding increase in number of infants admitted to the NICU who were born to transferred women from 43 before intervention to 201 after intervention, suggesting some of the increase in maternal transfer was due to anticipated neonatal care needs. The authors do not comment on statistical significance of this result.

Intervention Results:

Medicaid deliveries at the regional perinatal centers increased from 23.8% before the intervention to 33% in neonates between 500 and 999 grams (p<0.05) and was unchanged in neonates between 2001-2500 grams.

Intervention Results:

Among all VLBW infants, there was a change in birth location distribution. Of these infants, the percentage born in level III hospitals increased from 25.7% in period one to 46.8% in period four. The percentage born in level II hospitals decreased from 41.7% to 36% and the percentage born in level I also decreased from 32.6% to 17.2%.

An Illinois center's annual penetration rate into its regional market for the years 1973-1983 is presented and significant increases are found. The penetration rates of nine Illinois perinatal centers are calculated and wide discrepancies are found. Defining a high-risk regional cohort as a market stresses a perinatal center's obligation to its region.

Intervention Results:

Analysis of perinatal statistics from the Loyola University Perinatal Center from 1979 to 1986 supports: (1) increasing numbers of maternal and neonatal transports, with the number of maternal transports exceeding the number of neonatal transports since 1982; (2) increasing proportion of low birthweight and very low birthweight infants delivered at the perinatal center; (3) a decrease in the number of infants less than 1500 gm sent as neonatal transports; and (4) increasing proportion of neonatal transports with a birthweight greater than 2500 gm.

Intervention Results:

The percentage of children weighing less than 1500 g at birth born in Level III hospitals increased through 1999 but dropped subsequently, without ever returning to the 1994 level (P<0.0001). The overall caesarean rate climbed slowly but regularly from 1994 through 2006 (P<0.0001). Use of antenatal corticosteroids for women hospitalised for threatened preterm labour and in children born before 33 weeks has fluctuated since the release of the guideline (P>0.05). Exclusive breastfeeding at discharge from the maternity ward has increased slowly (P<0.0001). The percentage of deliveries with active management of the third stage of labour rose notably from 1999 to 2006 (P<0.0001), and smoking cessation during pregnancy rose slightly in 2006 (P<0.0001). Since 1994, early discharges have become slowly, slightly, but regularly more frequent for all women (P<0.0001). The guideline on episiotomies has had a slight positive effect in the short term (P<0.0001).

Intervention Results:

There has been a decrease in neonatal mortality rate from 13.4 to 6.9 during a period of time when there was a minimal decrease in the incidence of low-birth weight infants. The improved neonatal mortality has been associated with a shift in the frequency of birth of very low-birth weight (VLBW) infants to hospitals with level II and III perinatal services and relatively greater survival rates of VLBW infants born in these hospitals as compared to those born in level I hospitals. There was no decrease in fetal mortality in the same period of time.

Intervention Results:

Between 1982 and 1985 the antenatal transfer rate increased from 2.2% to 2.8% (p less than 0.003). The proportion of births of infants weighing 500 to 1499 g increased from 49% to 69% at the level III hospital. The neonatal transfer rate increased from 26.2% to 47.9% (p less than 0.05) for infants in this birth-weight category and decreased from 10.2% to 7.1% (p less than 0.03) for infants weighing 1500 to 2499 g. The death rate among infants of low birth weight was lowest among those born at the level III centre and decreased at all centres between 1982 and 1985.

Intervention Results:

After reorganisation, there were increases in the proportions of babies born at 27-28 weeks' gestation in hospitals providing the highest volume of neonatal specialist care (18% (631/3495) v 49% (1325/2724); odds ratio 4.30, 95% confidence interval 3.83 to 4.82; P<0.001) and in acute and late postnatal transfers (7% (235) v 12% (360) and 18% (579) v 22% (640), respectively; P<0.001). There was no significant change in the proportion of babies from multiple births separated by transfer (33% (39) v 29% (38); 0.86, 0.50 to 1.46; P=0.57). In epoch two, 32% of acute transfers were to a neonatal unit providing either an equivalent (n=87) or lower (n=26) level of specialist care.

Intervention Results:

The intervention in Iowa focused on increasing both level III and level II VLBW births due to population density concerns in Iowa. Among all VLBW infants, there were changes in the birth location distribution. Of these infants, there was a statistically significant increase in percentage born in level III hospitals from 6.7% to 22.6% (p<0.05)1 and an increase in births in level II hospitals from 26.9% to 35.6%. The percentage born in level I centers decreased from 68.2% to 41.8%.

Intervention Results:

Level I hospitals currently manage low-risk patients and report very low mortality rates. Level II facilities receive high-risk referrals, but selective referral occurs since the tertiary center accounts for a disproportionate number of fetal and neonatal deaths, and births weighting less than 1500 g.

Intervention Results:

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.

Intervention Results:

In both funded regions and comparison areas, the neonatal mortality rates decreased sharply over the decade of the 1970s. This decline was linked to shifts in the hospital of delivery that indicated antepartum risk identification and transfer of management of high-risk pregnancies to tertiary centers for delivery, a change in service pattern consistent with some aspects of regionalization. The centralization of high-risk deliveries appeared so widespread that the special effect of the RWJF program could not be detected.

Intervention Results:

Regulation of regionalization programs, data surveillance, review of adverse events, and consideration of geography and demographics were identified as mechanisms facilitating better measurement of risk-appropriate care. Antenatal or neonatal transfer arrangements, telemedicine networks, acquisition of funding, provision of financial incentives, and patient education comprised state actions for improving risk-appropriate care.
