Intervention Results:

Any hospital with NICU:

Although the change in percent of infants <35 weeks GA delivered at any hospital with NICU was statistically significant (p<0.01), the early increases in delivery seen in these hospitals after intervention in 2003 were lost after further follow-up. Over the study period, the percent of infants <35 weeks GA delivered at any hospital with NICU increased from 37.7% before intervention to a high of 44.1% in the year after intervention then subsequently decreased to 39.1% by then end of the follow-up period.
No ANGELS intervention components were statistically significantly associated with delivery at any NICU hospital (p>0.05).

UAMS (tertiary center):

Although the change in percent of infants <35 weeks GA delivered at UAMS was statistically significant (p<0.001), the early gains seen in percent delivered in the tertiary center appeared to be lost after further follow-up. Over the study period, the percent of infants <35 weeks GA delivered at UAMS tertiary center increased from 20.6% before intervention to a high of 27.3% in in the year after intervention then subsequently decreased to 19.6% by the end of the follow-up period.
Women living in counties with hospitals that participated in teleconferences on high-risk obstetrics with University of Arkansas for Medical Science (UAMS; an ANGELS program component) were more likely to deliver at UAMS (odds ratio (OR): 1.64, 95%; CI: 1.17 to 2.30; p=0.004). No other ANGELS program component was statistically significantly associated with an increased likelihood of delivery at UAMS (p>0.05).

Intervention Results:

Among total births at the level III hospital, the percentage that were VLBW increased from 6.7% before intervention to 8.7% after intervention (p<0.001).
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:

All LBW:

After the intervention, the case mix-adjusted probability of UAMS tertiary center delivery increased by 7.2% (p<0.05) among all LBW infants.
After the intervention, the percentage of non-NICU hospital births among all LBW births was over 50% and was not significantly different than before intervention (p-value not indicated).
Among all LBW infants, there was little change in birth location distribution after intervention. The percentage born in community hospitals with NICU decreased slightly from 30.1% to 28.8%. The percentage born in UAMS tertiary center was around 18% both before and after the intervention. The authors do not comment on statistical significance of these results.

ELBW:

Among all ELBW infants, there was little change in the birth location distribution. Of all ELBW infants, about 42% were born at UAMS tertiary center both before and after intervention. The percentage born in community hospitals with NICU decreased slightly from 35.3% to 30.7%. Data was not presented for births in non-NICU hospitals. The authors do not comment on statistical significance of these results.

ELBW subgroup:

After intervention, the case mix-adjusted probability of UAMS tertiary center delivery increased from 27.6% to 34.5% (p<0.01) among ELBW births to mothers residing more than 80 miles from UAMS.
Among ELBW infants born to mothers residing more than 80 miles from UAMS, there were some changes in birth location distribution. Of these infants, the percentage born in UAMS tertiary center increased from 40.7% to 46.8% after intervention. The percentage born in community hospital with NICU decreased from 26.8% to 17.5%. However, the percentage of non-NICU hospital births among this group increased from 32.5% to 35.7%. The authors do not comment on the statistical significance of these results.

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%.

Intervention Results:

During all but one of nine post-intervention years, the percentage of regional VLBW births delivered in level III hospitals was statistically significantly higher than what would have been expected had it been the same as the percentage of all regional births delivered at level III hospitals (p<0.001). This suggests that VLBW births compromise a larger percentage of total births at level III hospitals than would be expected if they followed the same birth location distribution as all infants in the region.

Intervention Results:

There was a change in the proportion of VLBW births out of total births at tertiary and outlying hospitals. Of total births at the tertiary center, VLBW infants represented a statistically significantly higher percentage after intervention than before (9.9% and 3.9% of total births, respectively; p<0.001). There was only a slight decrease in VLBW births as a proportion of total births in outlying hospitals from 1.39% to 1.17%. The authors do not comment of the statistical significance of that result.
There was a rapid increase in the number of maternal transfers for all reasons from 97 per year pre-intervention to around 350 per year post-intervention. The authors do not comment on statistical significance of this result.

Intervention Results:

Among all VLBW births, the percentage of level III births statistically significantly changed over the study period (p<0.0001). However, the percentage was increasing before intervention and through one year post-intervention, then subsequently decreased through the end of the follow-up period.
The author suggests that the intervention did not have a significant effect on the percentage of VLBW births in level III hospitals.

Intervention Results:

The proportion of VLBW births among total births in each hospital level shifted between the pretest and posttest period. In level III hospitals, the proportion of VLBW births among total births rose from 2.8% to 4.8% (p<0.05). In level II hospitals, the proportion of VLBW births among total births stayed the same (1.9%). In level I hospitals, there was a decrease from 1.6% to 1.1% of total births.

Intervention Results:

Among all women admitted to level I or II hospitals, the percentage of maternal transfer to level III hospitals increased from 2.2% of all admitted women (262 women) to 2.8% (p<0.003) after the intervention.
Among all women admitted to level I or II hospitals, maternal transfer of those with labor or threatened preterm labor before 37 weeks gestation to level III hospitals increased by 38% from 0.72% of all admitted women to 0.99% after intervention (p=0.024).
Among all infants born at 500-1499 gm, there was a statistically significant change in distribution of the number born in level III hospitals after intervention (p<0.001)

Intervention Results:

Among all VLBW infants in intervention regions, there was a shift towards increasing births in tertiary centers from 35.72% in the pretest period to 47.3% at the time of intervention to 59.4% in the posttest period.
Among all VLBW infants in comparison regions, there was also a shift towards increasing births in tertiary centers from 29.67% in the pre-test period to 34.2% at the time of intervention to 47.19% in the posttest period.
The authors do not comment on the statistical significance of these results. However, the authors do note that the difference in the rate of centralization of births in tertiary centers was not “strikingly greater” in the intervention regions as compared with the comparison regions.

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.
