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:

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:

After the intervention, there was a statistically significant decrease in the number of VLBW infants born in a level II hospital (p<0.01).

Intervention Results:

  • Among all VLBW births, there was a change in the birth location distribution. Of these infants, the percentage born in non-NICU hospitals with telemedicine intervention (targeted hospitals) statistically significantly decreased from 13.05% to 7.03% (p=0.0099).
  • Changes in other hospital levels (including UAMS tertiary center) were not statistically significant.

Intervention Results:

  • Among all infants born at 23 to 28 weeks GA, there was a statistically significant decrease in the percentage of non-tertiary hospital births from 30.1% to 24.6% (p<0.001).
    • This decrease was mostly driven by a large decrease among births at 23 to 24 weeks GA from 50.8% to 37.6% (p<0.001).
    • The decrease among all births at 25 to 26 and 27 to 28 weeks was not statistically significant (p= 0.075 and p= 0.194, respectively)

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.
