A Multifunctional, Low Cost and Sustainable Neonatal Database System.

Continuous improvement in the clinical performance of neonatal intensive care units (NICU) depends on the use of locally relevant, reliable data. However, neonatal databases with these characteristics are typically unavailable in NICUs using paper-based records, while in those using electronic records, the inaccuracy of data and the inability to customize commercial data systems limit their usability for quality improvement or research purposes. We describe the characteristics and uses of a simple, neonatologist-centered data system that has been successfully maintained for 30 years, with minimal resources and serving multiple purposes, including quality improvement, administrative, research support and educational functions. Structurally, our system comprises customized paper and electronic components, while key functional aspects include the attending-based recording of diagnoses, integration into clinical workflows, multilevel data accuracy and validation checks, and periodic reporting on both data quality and NICU performance results. We provide examples of data validation methods and trends observed over three decades, and discuss essential elements for the successful implementation of this system. This database is reliable and easily maintained; it can be developed from simple paper-based forms or used to supplement the functionality and end-user customizability of existing electronic medical records. This system should be readily adaptable to NICUs in either high- or limited-resource environments.

Maternal Obesity-Associated Neonatal Morbidities in Early Newborn Period.

Maternal obesity has been associated with pregnancy-related complications and neonatal morbidities. The primary aim of this study was to evaluate early neonatal morbidities associated with maternal obesity from the infant-mother dyad data set at a single, large Regional Perinatal Center (RPC) in NY. A retrospective chart review of all mother-infant dyads born from January 2009 to December 2019 was done. Maternal obesity was defined using the NIH definition of pre-pregnancy body mass index (BMI) ≥ 30 Kg/m2. Maternal data included pre-pregnancy BMI, gestational diabetes, hypertension, and mode of delivery. Neonatal data recorded the birth weight, gestational age, respiratory support after delivery, diagnosis of transient tachypnea of the newborn (TTN), respiratory distress syndrome (RDS), neonatal hypoglycemia (NH), and hypoxic-ischemic encephalopathy (HIE). Diagnosis of TTN, RDS, NH, and HIE was defined by the service neonatologist and cross-checked by the data system review neonatologist. Medical records of 22,198 infant-mother dyads included in the study had 7,200 infants (32.4%) born to obese mothers and 14,998 infants (67.6%) born to non-obese women. There was a statistically significant increase in the diagnosis of gestational diabetes, gestational hypertension, and cesarean deliveries in obese mothers. Diagnosis of TTN, RDS, and NH was significantly higher in infants born to obese mothers, while HIE incidence was similar in both the groups. Infants born to obese mothers are more likely to be delivered by cesarean section and are at a higher risk of diagnosis of transient tachypnea of newborn, respiratory distress syndrome, and hypoglycemia in the early neonatal period.

The Impact of Maternal Obesity on NICU and Newborn Nursery Costs.

Background: Research on the effects of maternal obesity on neonates has focused on clinical outcomes. Despite growing interest in obesity as a driver of healthcare expenditure, the financial impact of maternal obesity in the neonatal setting is little understood. Objective: To determine if maternal obesity is associated with higher incurred costs in NICU and full-term nursery. Methods: Data for all live births (1/1/14-12/31/19) at our academic medical center was obtained from the New York State Perinatal Data System for infants >23 weeks gestational age. Financial data was obtained from the hospital's cost-processing application. Infants with missing clinical and/or financial data were excluded. The NIH definition of obesity was used (BMI ≥ 30 kg/m2) to separate infants born to obese and non-obese mothers. Student's t-tests and chi square tests were used to compare maternal data, delivery, and infant outcomes between both groups. A logistic regression model was used to compare infant outcomes using odds ratios while controlling for maternal risk factors (smoking status, pre-pregnancy and gestational diabetes, pre-pregnancy and gestational hypertension). Multivariate regression analysis adjusting for maternal risk factors was also used to compare length-of-stay, total and direct costs in the NICU and full-term nursery between infant groups. Results: Of the 11,610 pregnancies in this retrospective study, obese mothers more frequently had other risk factors (smoke, pre-pregnancy and gestational diabetes, and pre-pregnancy and gestational hypertension). Infants born to obese mothers were more often preterm, had Cesarean delivery, lower APGAR scores, required assisted ventilation in the delivery room, and required NICU admission. Adjusting for maternal risk factors, infants born to obese mothers were less frequently preterm (OR 0.82 [0.74-0.91], p < 0.01) and had NICU stays (OR 0.98 [0.81-0.98], p = 0.02), but more frequently had Cesarean births (OR 1.54 [1.42-1.67], p < 0.01). They also had longer adjusted LOS (2.03 ± 1.51 vs. 1.92 ± 1.45 days, p < 0.01) and higher mean costs per infant in the full-term nursery ($3,638.34 ± $6,316.69 vs. $3,375.04 ± $4,994.18, p = 0.03) but not in NICU. Conclusions: Maternal obesity correlates with other risk factors. Prolonged maternal stay may explain increased LOS and costs in the full-term nursery for infants born to obese mothers, as infants wait to be discharged with mothers.

Association of Maternal Obesity and Neonatal Hypoxic-Ischemic Encephalopathy.

Objective: More women are obese at their first prenatal visit and then subsequently gain further weight throughout pregnancy than ever before. The impact on the infant's development of neonatal hypoxic ischemic encephalopathy (HIE) has not been well studied. Using defined physiologic and neurologic criteria, our primary aim was to determine if maternal obesity conferred an additional risk of HIE. Study Design: Data from the New York State Perinatal Data System of all singleton, term births in the Northeastern New York region were reviewed using the NIH obesity definition (Body Mass Index (BMI) ≥ 30 kg/m2). Neurologic and physiologic parameters were used to make the diagnosis of HIE. Physiologic criteria included the presence of an acute perinatal event, 10-min Apgar score ≤ 5, and metabolic acidosis. Neurologic factors included hypotonia, abnormal reflexes, absent or weak suck, hyperalert, or irritable state or evidence of clinical seizures. Therapeutic hypothermia was initiated if the infant met HIE criteria when assessed by the medical team. Logistic regression analysis was used to assess the effect of maternal body mass index on the diagnosis of HIE. Results: In this large retrospective cohort study we evaluated outcomes of 97,488 pregnancies. Infants born to obese mothers were more likely to require ventilatory assistance and have a lower 5-min Apgar score. After adjusting for type of delivery and maternal risk factors, infants of obese mothers were diagnosed with HIE more frequently than infants of non-obese mothers, OR 1.96 (1.33-2.89) (p = 0.001). Conclusion: Infants of obese mothers were significantly more likely to have the diagnosis of HIE.

Using MMI Comments for Medical School Admissions Decision-Making.

This article was migrated. The article was marked as recommended. Introduction Multiple mini-interview (MMI) comments can help to reveal an underlying personality or behavioral flaw that the numerical scores are not designed to illustrate. The importance of the comments provided by interviewers has not been documented in the literature. This study sought to examine whether MMI comments influenced admission committee decision-making. Methods Five thousand de-identified interview comments from a subset of 625 medical school applicants were reviewed by study raters who followed a rubric that outlined scoring assignments based upon the number of positive and negative statements made by MMI interviewers. The presence of extremely negative MMI comments was also evaluated. Results MMI score strongly correlated with MMI comment score assigned by the raters and contributed to overall committee score and decision for acceptance or rejection to medical school. The presence of one negative outlier comment score alone did not impact committee score or acceptance; however, when extremely negative attributes were identified by study raters within an outlier comment, this was associated with a reduction of final committee score and higher incidence of rejection. Conclusions A strong correlation existed between the MMI comments and overall MMI score. Both MMI comments and MMI scores predict acceptance to medical school. The additional value of the MMI comments lies in the extremely negative outlier comments.

Physical examination score predicts need for surgery in neonates with necrotizing enterocolitis.

OBJECTIVE: To evaluate the utility of a standardized physical exam score (PE-NEC) in predicting need for surgery or death in neonates with necrotizing enterocolitis (NEC). METHODS: This prospective, multicenter, observational study was conducted from 3/1/14 to 2/29/16 with three regional perinatal centers in upstate New York. Infants with NEC Bell's Stage ≥ 2 had physical exams and laboratory data recorded at 12-24 h intervals for 48 h following diagnosis. PE-NEC score was comprised of seven components: bowel sounds, capillary refill time, abdominal wall erythema, girth, discoloration, induration, and tenderness. Surgical timing was determined by surgeons blinded to the PE-NEC score. Optimal sensitivity and specificity of PE-NEC score for surgery/death (primary outcome) was determined by receiver operating characteristic curve analysis. RESULTS: Of 100 infants with NEC, 5 had pneumoperitoneum at diagnosis and were excluded yielding 95 for analyses. Of those, 35 infants experienced the primary outcome: 3 died from NEC prior to surgery and 32 had surgery (30 laparotomies, 2 drains). The PE-NEC score was found to be sensitive and specific for need for surgery/death (AUC = 0.89, 95% CI 0.82-0.97); a score of ≥3 had a sensitivity of 0.88 (95% CI 0.72-0.97), specificity of 0.81 (95% CI 0.69-0.90). All components of the PE-NEC score were more likely to be present among infants with surgical NEC or who died. CONCLUSION: PE-NEC score is sensitive and specific in predicting need for surgery in infants with NEC and should be validated as a clinical decision-making tool.

Impact of maternal obesity on very preterm infants.

OBJECTIVE: Infants born at less than 34 weeks' gestational age are at higher risk for morbidity and mortality. Data are limited on the impact of maternal obesity on the very preterm infant. This study reviewed whether maternal obesity further increases the intensive care needs of very preterm infants of less than 34 weeks' gestation. METHODS: Maternal and neonatal data for live-born singleton births of 23 0/7 to 33 6/7 weeks' gestation delivering in upstate New York were reviewed. BMI categorization followed the National Institutes of Health BMI classification that subdivides obesity into three ascending BMI groups. RESULTS: Records were obtained on 1,224 women, of whom 31.6% were classified with obesity. Despite similar mean gestational age (31 to 31.6 weeks, P = 0.57) and birth weight (1,488 to 1,569 g, P = 0.51) of the infants in the BMI categories, delivery room (DR) resuscitation was more common for infants of women with level III obesity (63.2%, P = 0.04) with a trend toward the continued need for assisted ventilation (54.7%, P = 0.06). CONCLUSIONS: Preterm infants of women with level III obesity were more likely to require DR resuscitation with a trend to continued need for ventilatory support beyond 6 hours of age. This could impact utilization of DR resources at delivering hospitals.

Surfactant administration by transient intubation in infants 29 to 35 weeks' gestation with respiratory distress syndrome decreases the likelihood of later mechanical ventilation: a randomized controlled trial.

OBJECTIVE: To assess, among premature infants with early respiratory distress syndrome (RDS), the effect of one dose of intratracheally administered surfactant followed by extubation to nasal continuous positive airway pressure (NCPAP) on subsequent mechanical ventilation (MV), when compared with NCPAP alone. STUDY DESIGN: Randomized, blinded trial in infants 29 to 35 weeks' gestation with mild-to-moderate RDS requiring supplemental oxygen and NCPAP. Infants were randomized to intubation, surfactant treatment, and immediate extubation (surfactant group N=52), or to no intervention (control group N=53). All infants were subsequently managed with NCPAP. RESULTS: Need for later MV was 70% in the control group and 50% in the surfactant group. Surfactant group subjects had lower inspired oxygen fraction (FiO(2)) after study intervention and were less likely to require subsequent surfactant. Overall surfactant use, duration of O(2) therapy, length of stay, and bronchopulmonary dysplasia were unaffected. CONCLUSION: Among premature infants with mild-to-moderate RDS, transient intubation for surfactant administration reduces later MV.
