Background: Neonatal intensive care unit (NICU) admission is often due to specific cardiovascular conditions. Low birthweight, another common reason for NICU admission, is also linked to later cardiovascular risk. Within the past decade, the rate of NICU admissions in the United States has significantly increased. Identification of emerging risk factors for NICU admission will help inform efforts to reduce the number of newborns requiring intensive care. Methods: The objective of this study was to identify risk factors for NICU admission in all infants born in West Virginia (WV), 2012-2017, via Project WATCH. Fifteen exposure variables including demographics, maternal and infant characteristics, were included in multivariable logistic regression analyses, stratified by preterm and term births. Results: Of 120,894 neonates, 6,393 (5.3%) were admitted to NICU. Among preterm infants (Table 1), predictors included male sex (OR: 1.11), insurance status (OR: 1.29), APGAR scores less than or equal to 3 (OR: 2.57), maternal diabetes (OR: 1.68 and 2.01), residence outside WV (OR: 1.27), intrauterine substance exposure (OR: 1.94), congenital abnormalities (OR: 2.58), and low birthweight (OR: 1.73 and 6.64). Risk factors in term infants included all factors identified for preterm infants, as well as maternal smoking, maternal age, and number of previous pregnancies. Conclusions: In addition to infant characteristics predictive of NICU admission (e.g., birthweight and APGAR score), socioeconomic factors (e.g., insurance status and rurality) and preventable risk factors (e.g., maternal smoking and substance use) provide an opportunity for intervention during pregnancy, with the goal to decrease the number of newborns requiring intensive care.

Abstract Background Currently, there is a disagreement between guidelines regarding platelet count cut-off values as a sign of maternal organ damage in pre-eclampsia; the American College of Obstetricians and Gynecologists guidelines state a cut-off value of < 100 × 109/L; however, the International Society for the Study of Hypertension in Pregnancy guidelines specify a cut-off of < 150 × 109/L. We evaluated the effect of mild thrombocytopenia: platelet count < 150 × 109/L and ≥ 100 × 109/L on clinical features of pre-eclampsia to examine whether mild thrombocytopenia reflects maternal organ damage in pre-eclampsia. Methods A total of 264 women were enrolled in this study. Participants were divided into three groups based on platelet count levels at delivery: normal, ≥ 150 × 109/L; mild thrombocytopenia, < 150 × 109/L and ≥ 100 × 109/L; and severe thrombocytopenia, < 100 × 109/L. Risk of severe hypertension, utero-placental dysfunction, maternal organ damage, preterm delivery, and neonatal intensive care unit admission were analyzed based on platelet count levels. Estimated relative risk was calculated with a Poisson regression analysis with a robust error. Results Platelet counts indicated normal levels in 189 patients, mild thrombocytopenia in 51 patients, and severe thrombocytopenia in 24 patients. The estimated relative risks of severe thrombocytopenia were 4.46 [95 % confidence interval, 2.59–7.68] for maternal organ damage except for thrombocytopenia, 1.61 [1.06–2.45] for preterm delivery < 34 gestational weeks, and 1.35 [1.06–1.73] for neonatal intensive care unit admission. On the other hand, the estimated relative risks of mild thrombocytopenia were 0.97 [0.41–2.26] for maternal organ damage except for thrombocytopenia, 0.91 [0.62–1.35] for preterm delivery < 34 gestational weeks, and 0.97 [0.76–1.24] for neonatal intensive care unit admission. Conclusions Mild thrombocytopenia was not associated with severe features of pre-eclampsia and would not be suitable as a sign of maternal organ damage.

<p><strong>Objective:</strong> The aim of this study was to investigate the effect of some maternal and neonatal clinical parameters on the neonatal intensive care unit admission rates of neonates born to mothers who had preeclampsia. </p><p><strong>Study Design:</strong> Study included 402 singleton pregnant women with preeclampsia who admitted to Maternal-Fetal Medicine Unit of Zeynep Kamil Children and Women’s Health Training and Research Hospital. Pregnancies with uterine rupture, chorioamnionitis and congenital malformations were excluded. Some maternal and neonatal clinical characteristics were assessed to predict neonatal intensive care unit admission.</p><p><strong>Results:</strong> Among 402 neonates, 140 (35%) of them had an indication for neonatal intensive care unit admission, among 140 neonates, 136 (97%) of them were preterm neonates. Comparison of groups with and without neonatal intensive care unit admission indicated significant differences between groups in terms of gestational age, Apgar scores at 1st and 5th minutes, birth weight, some maternal laboratory parameters (Hemoglobin, hematocrit, alanine aminotransferase, aspartate aminotransferase, albumin). In multivariate analysis, among all study population, gestational age at delivery, birth weight and Apgar scores were found to be significantly associated with neonatal intensive care unit admission. On the other hand, in subgroup of term neonates, none of the variables was shown to be associated with neonatal intensive care unit admission.</p><p><strong>Conclusion:</strong> Gestational age at delivery and the birth weight are the main risk factors for neonatal intensive care unit admission of neonates born to mothers who had preeclampsia.</p>
