OBJECTIVES:: Our purpose was to examine the contribution of hospital factors (e.g., reimbursement sources, teaching status) to the rate of nontransfer of <1250?g infants born in nontertiary hospitals in Illinois. We chose nontransfer as a marker of the extent to which there have been structural changes in the regionalized perinatal care system in Illinois. STUDY DESIGN:: Using data from live birth certificates (1989-1996), from the American Hospital Association's Annual Survey of Hospitals (1990 to 1996), and Illinois hospital discharge records (1992 to 1996), we simultaneously assessed the effect of hospital and individual factors on nontransfer of infants <1250?g (n=2904). RESULTS:: When adjusted for individual risk factors, several hospital factors were associated with nontransfer. These include birth in a Level II+hospital (odds ratios(OR) 3.75; 95% CI 2.29, 5.29), high Medicaid revenues (OR 1.97; 95% CI 1.58, 2.47), high HMO revenues (OR 1.39; 95% CI 1.11, 2.28), and status as a teaching hospital (OR 1.63; 95% CI 1.30, 2.09). CONCLUSIONS:: This study suggests that there should be careful consideration of the role of hospital factors in perinatal deregionalization in order to preserve the improvements in maternal and infant outcomes associated with regionalized perinatal care.Journal of Perinatology (2004) 24, 351-359. doi:10.1038/sj.jp.7211101 Published online 15 April 2004 [ABSTRACT FROM AUTHOR]

Objective: To estimate the prevalence of meconium-stained amniotic fluid and meconium aspiration syndrome, as well as the differences in case fatality from meconium aspiration syndrome, between non-Hispanic black and non-Hispanic white infants., Methods: We studied non-Hispanic black and non-Hispanic white live births with weights greater than 2.5 kg and gestational ages greater than 35 weeks, using the linked US birth and infant death cohorts for three periods: 1989-1991, 1995-1997, and 1998-2000. We used logistic regression to estimate the risks of meconium-stained amniotic fluid and meconium aspiration syndrome and to estimate the case fatality of meconium aspiration syndrome by maternal race, birth weight, period, and pregnancy complications., Results: Risk of meconium-stained amniotic fluid was 80% higher in non-Hispanic blacks when compared with non-Hispanic whites (birth weight-adjusted odds ratio [OR], 1.81, 95% confidence interval [CI] 1.80, 1.82). The prevalence of pregnancy complications did not explain this racial disparity. Risk of meconium aspiration syndrome in non-Hispanic blacks was 67% higher when compared with non-Hispanic whites (birth weight-adjusted OR 1.67, 95% CI 1.64, 1.70). The case fatality rate of meconium aspiration syndrome was similar between non-Hispanic blacks and non-Hispanic whites in the three periods, with rates of 15.5, 15.2, and 11.2 per 1000 in non-Hispanic blacks and 13.5, 11.2, and 10.1 per 1000 in non-Hispanic whites in 1989-1991, 1995-1997, and 1998-2000, respectively., Conclusion: Our results suggest that when compared with non-Hispanic whites, non-Hispanic blacks are at significantly greater risk for meconium-stained amniotic fluid and meconium aspiration syndrome but not for meconium aspiration syndrome case fatality.
