RESUMO
Background: Prematurity and congenital heart disease (CHD) are the leading causes of neonatal mortality and morbidity. Limited data are available about the outcomes of premature infants with severe CHD. Methods: We queried The National Inpatient Database using ICD-10 codes for premature patients (<37 weeks) with severe CHD from 2016 to 2020. Severe CHDs were grouped into three categories: A. left-sided lesions with impaired systemic output, B. Cyanotic CHD, and C. Shunt lesions with pulmonary overcirculation. Patients with isolated atrial or ventricular septal defects and patent ductus arteriosus were excluded. We also excluded patients with chromosomal abnormalities and major congenital anomalies. Patients' demographics, clinical characteristics, and outcomes were evaluated by comparing premature infants with vs. without CHD adjusting for gestational age (GA), birth weight, and gender. Results: A total of 27710 (1.5%) out of 1,798,245 premature infants had severe CHD. This included 27%, 58%, and 15% in groups A, B, and C respectively. The incidence of severe CHD was highest between 25 and 28 weeks of gestation and decreased significantly with increasing GA up to 36 weeks (p < 0.001). Premature infants with severe CHD had a significantly higher incidence of neonatal morbidities including necrotizing enterocolitis (NEC) [OR = 4.88 (4.51-5.27)], interventricular hemorrhage [OR = 6.22 (5.57-6.95)], periventricular leukomalacia [OR = 3.21 (2.84-3.64)] and bronchopulmonary dysplasia [OR = 8.26 (7.50-10.06) compared to preterm infants of similar GA without CHD. Shunt lesions had the highest incidence of NEC (8.5%) compared to 5.3% in cyanotic CHD and 3.7% in left-sided lesions (p < 0.001). Mortality was significantly higher in premature infants with CHD compared to control [11.6% vs. 2.5%, p < 0.001]. Shunt lesions had significantly higher mortality (11.0%) compared to those with left-sided lesions (8.3%) and cyanotic CHD (6.4%), p < 0.001. Conclusion: Premature infants with severe CHD are at high risk of neonatal morbidity and mortality. Morbidity remains increased across all GA groups and in all CHD categories. This significant risk of adverse outcomes is important to acknowledge when managing this patient population and when counseling their families. Future research is needed to examine the impact of specific rather than categorized congenital heart defects on neonatal outcomes.
RESUMO
Objective: To examine disparity in hospital mortality among Caucasian (C) and African American (AA) neonates born at different gestational ages (GA). Methods: De-identified national inpatient data were obtained from the Healthcare Cost and Utilization Project (HCUP) from the Agency for Healthcare Research and Quality (AHRQ) for the years 2011-2018. We compared the odds ratio for mortality among C and AA infants by sex and GA category. Analyses were repeated after controlling for multiple maternal and neonatal confounding variables in a logistic regression model. Results: The study included 18,758,233 infants; 78.3% of them were C and 21.7% were AA. Compared to C population, AA population has a significantly higher mortality in term infants born at GA ≥ 36 weeks. The racial/ethnic disparity in preterm infants was inconsistent without any difference at 35-36 weeks in male and female infants. The overall aOR for mortality in AA in all male preterm infants ≤36 weeks was 1.44 (1.39-1.49), <0.01; and the overall aOR for mortality in AA in all preterm female infants ≤36 weeks was 1.38 (1.33-1.44). Conclusion: Racial/Ethnic disparity in hospital mortality exists with higher AA mortality in infants born with GA > 36 weeks and less AA mortality in infants born with GA 24-26 weeks.
RESUMO
Background: Reports on the survival of infants born at periviable gestation (GA of ≤24 weeks and birth weight of <500 gm) vary significantly. We aimed to determine hospital factors associated with their survival and to assess the trend for the timing of postnatal mortality in these periviable infants. Methods: We utilized the de-identified National Inpatient Sample (NIS) dataset of the Healthcare Cost and Utilization Project (HCUP) from the Agency for Healthcare Research and Quality (AHRQ). National data were analyzed for the years 2010-2018. Hospitals were categorized according to delivery volume, USA regions, and teaching status. Results: We identified 33,998,014 infants born during the study period; 76,231 infants were ≤24 weeks. Survival at birth and first 2 days of life was greatest in urban teaching hospitals in infants <24 weeks and those who completed 24 weeks, respectively. The Northeast region has the lowest survival rate. There was a significant delay in the postnatal day of mortality in periviable infants. Conclusions: Hospital factors are associated with increased survival rates. Improved survival in large teaching hospitals supports the need for the regionalization of care in infants born at the limits of viability. There was a significant delay in the postnatal mortality day.
RESUMO
BACKGROUND: Controversial data exist about the impact of Down syndrome on outcomes after surgical repair of atrioventricular septal defect. AIMS: (A) assess trends and outcomes of atrioventricular septal defect with and without Down syndrome and (B) determine risk factors associated with adverse outcomes after atrioventricular septal defect repair. METHODS: We queried The National Inpatient Sample using International Classification of Disease codes for patients with atrioventricular septal defect < 1 year of age from 2000 to 2018. Patients' characteristics, co-morbidities, mortality, and healthcare utilisation were evaluated by comparing those with versus without Down syndrome. RESULTS: In total, 2,318,706 patients with CHD were examined; of them, 61,101 (2.6%) had atrioventricular septal defect. The incidence of hospitalisation in infants with atrioventricular septal defect ranged from 4.5 to 7.5% of all infants hospitalised with CHD per year. A total of 33,453 (54.7%) patients were associated with Down syndrome. Double outlet right ventricle, coarctation of the aorta, and tetralogy of Fallot were the most commonly associated with CHD in 6.9, 5.7, and 4.3% of patients, respectively. Overall atrioventricular septal defect mortality was 6.3%. Multivariate analysis revealed that prematurity, low birth weight, pulmonary hypertension, and heart block were associated with mortality. Down syndrome was associated with a higher incidence of pulmonary hypertension (4.3 versus 2.8%, p < 0.001), less arrhythmia (6.6 versus 11.2%, p < 0.001), shorter duration for mechanical ventilation, shorter hospital stay, and less perioperative mortality (2.4 versus 11.1%, p < 0.001). CONCLUSION: Trends in atrioventricular septal defect hospitalisation had been stable over time. Perioperative mortality in atrioventricular septal defect was associated with prematurity, low birth weight, pulmonary hypertension, heart block, acute kidney injury, and septicaemia. Down syndrome was present in more than half of atrioventricular septal defect patients and was associated with a higher incidence of pulmonary hypertension but less arrhythmia, lower mortality, shorter hospital stay, and less resource utilisation.

INTRODUCTION: Preterm birth is a leading cause for prolonged length of stay (LOS) in the hospital. In the USA, the rate of preterm birth is around 10.5%, thereby contributing substantially to the burden of hospitalization. The interaction of demographic, financial, and hospital factors with LOS of preterm infants has not been studied. OBJECTIVE: To assess the effect of demographic, financial, and hospital factors on LOS of surviving preterm infants born at 23 0/7-36 6/7 weeks of gestational age (GA). METHODS: We utilized de-identified patient information from the Healthcare Cost and Utilization Project (HCUP) from 2016-2020. All infants with GA between 23 0/7 and 36 6/7 weeks were identified. ANOVA test was used to assess LOS differences at different GA. Cochran-Armitage test was used for trend analyses. RESULTS: A total of 1,359,280 surviving premature infants were included in the study. LOS was significantly (p < 0.001) impacted by GA, ethnic group, hospital size and type, and US geographic region. LOS was not affected by sex or type of health insurance. CONCLUSION: LOS of preterm infants is significantly affected by multiple demographic factors that are potentially modifiable. These findings can remarkably help policymakers and stakeholders optimize interventions and resource allocations for preterm infants.

Objectives: to evaluate the accessibility, success rate, and attributable complications and to describe the maneuver for central line insertion via proximal basilic or axillary veins in neonates. Methods: This retrospective study included all infants admitted to the neonatal intensive care unit and had an axillary central line inserted or attempted. Success rate, complications, and outcomes were reviewed. Results: Axillary central line was attempted in 85 infants and was successful in 78 infants with a success rate of 91.7%. The median postnatal age of patients was 8 days (2 days-92 days), and the median weight of patients at the procedure was 2600 g (590 g-3900 g). The median corrected gestational age of patients at the procedure was 36 weeks (23 weeks-46 weeks). No serious complication was observed in any of the 85 infants. Conclusion: This study demonstrated a high success rate for insertion of proximal basilic and axillary veins central lines in neonates with difficult vascular access. This procedure was feasible in very low birth and extremely low birth preterm infants, especially in those who failed previous central line attempts.
RESUMO
OBJECTIVE: We aimed to look for the mortality of Black and White Neonates and compare the Black and White neonates' mortalities after stratifying the population by many significant epidemiologic and hospital factors. DESIGN/METHOD: We utilized the National Inpatient Sample (NIS) dataset over seven years from 2012 through 2018 for all neonates ≤ 28 days of age in all hospitals in the USA. Neonatal characteristics used in the analysis included ethnicity, sex, household income, and type of healthcare insurance. Hospital characteristics were urban teaching, urban non-teaching, and rural. Hospital location was classified according to the nine U.S. Census Division regions. RESULTS: Neonatal mortality continues to be higher in Black populations: 21,975 (0.63%) than in White populations: 35,495 (0.28%). Government-supported health insurance was significantly more among Black populations when compared to White (68.8% vs. 35.3% p < 0.001). Household income differed significantly; almost half (49.8%) of the Black population has income ≤ 25th percentile vs. 22.1% in White. There was a significant variation in mortality in different U.S. LOCATIONS: In the Black population, the highest mortality was in the West North Central division (0.72%), and the lower mortality was in the New England division (0.51%), whereas in the White population, the highest mortality was in the East South-Central division (0.36%), and the lowest mortality was in the New England division (0.21%). Trend analysis showed a significant decrease in mortality in Black and White populations over the years, but when stratifying the population by sex, type of insurance, household income, and type of hospital, the mortality was consistently higher in Black groups throughout the study years. CONCLUSIONS: Disparities in neonatal mortality continue to be higher in Black populations; there was a significant variation in mortality in different U.S. LOCATIONS: In the Black population, the highest mortality was in the West North Central division, and the lower mortality was in the New England division, whereas in the White population, the highest mortality was in the East South Central division, and the lowest mortality was in the New England division. There has been a significant decrease in mortality in Black and White populations over the years, but when stratifying the population by many significant epidemiologic and hospital factors, the mortality was consistently higher in Black groups throughout the study years.
RESUMO
Background: Estimating and analyzing trends and patterns of health loss are essential to promote efficient resource allocation and improve Peru's healthcare system performance. Methods: Using estimates from the Global Burden of Disease (GBD), Injuries, and Risk Factors Study (2019), we assessed mortality and disability in Peru from 1990 to 2019. We report demographic and epidemiologic trends in terms of population, life expectancy at birth (LE), mortality, incidence, prevalence, years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life-years (DALYs) caused by the major diseases and risk factors in Peru. Finally, we compared Peru with 16 countries in the Latin American (LA) region. Results: The Peruvian population reached 33.9 million inhabitants (49.9% women) in 2019. From 1990 to 2019, LE at birth increased from 69.2 (95% uncertainty interval 67.8-70.3) to 80.3 (77.2-83.2) years. This increase was driven by the decline in under-5 mortality (-80.7%) and mortality from infectious diseases in older age groups (+60 years old). The number of DALYs in 1990 was 9.2 million (8.5-10.1) and reached 7.5 million (6.1-9.0) in 2019. The proportion of DALYs due to non-communicable diseases (NCDs) increased from 38.2% in 1990 to 67.9% in 2019. The all-ages and age-standardized DALYs rates and YLLs rates decreased, but YLDs rates remained constant. In 2019, the leading causes of DALYs were neonatal disorders, lower respiratory infections (LRIs), ischemic heart disease, road injuries, and low back pain. The leading risk factors associated with DALYs in 2019 were undernutrition, high body mass index, high fasting plasma glucose, and air pollution. Before the COVID-19 pandemic, Peru experienced one of the highest LRIs-DALYs rates in the LA region. Conclusion: In the last three decades, Peru experienced significant improvements in LE and child survival and an increase in the burden of NCDs and associated disability. The Peruvian healthcare system must be redesigned to respond to this epidemiological transition. The new design should aim to reduce premature deaths and maintain healthy longevity, focusing on effective coverage and treatment of NCDs and reducing and managing the related disability.

OBJECTIVE: To assess the association of maternal diabetes mellitus (DM) with intraventricular hemorrhage (IVH) and other intracranial hemorrhages (ICH) in newborns. STUDY DESIGN: We analyzed the National Inpatient Sample dataset and compared prevalence of IVH and other subtypes of ICH in infants of diabetic mothers (IDMs) vs. those born to mothers without DM. Regression models were used to control for demographic and clinical confounding variables. RESULT: A total of 11,318,691 infants were included. Compared to controls, IDMs had increased prevalence of IVH (aOR = 1.18, CI: 1.12-1.23, p < 0.001) and other ICH (aOR = 1.18, CI: 1.07-1.31, p = 0.001). Severe IVH (grades 3 & 4) was encountered less frequently in IDMs (aOR = 0.75, CI: 0.66-0.85, p < 0.001) than controls. Gestational DM was not associated with increased IVH after controlling for the demographic, clinical and perinatal confounders in the logistic regression model (aOR = 1.04, CI: 0.98-1.11, p = 0.22). CONCLUSION: Chronic maternal DM is associated with increased neonatal IVH and other ICH but not severe IVH. This association needs to be confirmed in further studies.

Using the US National Inpatient Sample dataset (2010 to 2018), we compared outcomes of neonates with Tetralogy of Fallot who had early primary surgical repair (1726 neonate) and those who had staged palliative intervention with transcatheter (1702 neonate) or surgical palliative shunt (2661 neonate).
RESUMO
Background: Substantial differences exist in the approach to resuscitating infants born at periviable gestation. Evaluation of current survival may help guide prenatal counselling and provide accurate expectations of clinical outcomes. We aimed to assess the US national survival trends in periviable infants born at gestational age (GA) ≤24 weeks. Methods: We used de-identified patient data obtained from the US Healthcare Cost and Utilization Project (HCUP) from 2007 to 2018. All infants with documented GA ≤24 weeks were included. The Cochran-Armitage test was used for trend analyses. Regression analyses were conducted for variables associated with survival. Findings: A total of 44,628,827 infant records were identified with 124,345 (0.28%) infants born ≤24 weeks; of those, 77,050 infants <24 weeks and 47,295 infants had completed 24 weeks. Survival rates for infants <24 weeks and with completed 24 weeks were 15.4% and 71.6%, respectively, with higher survival over the years (Z = 9.438, P<0.001 & Z = 3.30, P<0.001, respectively). Survival was lower in males compared to females (aOR = 0.96, CI: 0.93-0.99 & aOR = 0.94, CI: 0.92-0.96, respectively) and with private insurance compared to public insurance (aOR = 0.74, CI: 0.71-0.77 & aOR = 0.67, CI: 0.65-0.69, respectively). Survival was higher when birth weight was >500 g compared to ≤500 g (aOR = 4.62, CI:3.23-5.02 & aOR = 5.44, CI: 4.59-5.84, respectively). Black (aOR = 1.33, CI: 1.31-1.36 & aOR = 1.24, CI: 1.20-1.32, respectively) and Hispanic (aOR = 1.29, CI: 1.27-1.32 & aOR = 1.27, CI: 1.22-1.30, respectively) had higher survival than White. Interpretation: There is a national increase in survival over the years in infants born at periviable GA. BW >500 is associated with >4 folds higher survival compared to ≤500 g. The results of this study should be cautiously interpreted as long-term outcomes are unknown. Funding: This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors.
RESUMO
OBJECTIVE: The objective of this study was to assess the prevalence and trends for neonatal hyperbilirubinemia, and the development of bilirubin neurotoxicity in the USA. STUDY DESIGN: We used a de-identified national dataset for the years 2002-2017. The study included all newborn inpatients with postnatal age ≤28 days. Cochran-Armitage trend test was used for trend analyses. Regression analyses were performed and adjusted odds ratios (aOR) were reported. RESULTS: The study included 57,989,476 infants; of them 53,259,758 (91.8%) were term infants and 4,725,178 (8.2%) were preterm infants. Bilirubin neurotoxicity decreased over the years in term infants (Z = 0.36, p = 0.03) without change in preterm infants (Z = 42.5, p = 0.12). Black neonates were less likely to be diagnosed with hyperbilirubinemia than White neonates (aOR = 0.77, 95% confidence interval (CI): 0.77-0.78, p < 0.001) and more likely to develop bilirubin neurotoxicity than White neonates (aOR = 3.0.5, 95% CI: 2.13-4.36, p < 0.001). Bilirubin neurotoxicity rate in the overall population was 2.4 per 100,000 live births. CONCLUSIONS: Bilirubin neurotoxicity has significantly decreased in term infants and did not change in preterm infants. Despite the less diagnosis of hyperbilirubinemia in Black newborns, they are disproportionately at increased risk of developing bilirubin neurotoxicity when compared to White newborns. IMPACT: In this article, we analyzed the National Inpatient Database. This is the largest study of its kind using data on 57,989,476 neonates. The article has multiple novel findings: (1) it demonstrated that utilization of phototherapy has increased significantly over the years, (2) the rate of kernicterus for neonates decreased in term infants and did not change in preterm babies, (3) kernicterus was mostly encountered in infants without isoimmunization jaundice, and (4) there is a clear racial disparity in neonatal jaundice; although Black newborns have less neonatal jaundice, they are at increased risk of developing kernicterus.

OBJECTIVES: To assess the prevalence and outcomes of spontaneous intestinal perforation (SIP) in very low birth weight infants. STUDY DESIGN: This cross-sectional study utilized the National Inpatient Sample dataset for the years 2002-2017. All premature infants with birth weight (BW) <1500 g and with gestational age (GA) ≤32 weeks were included. Analyses were repeated after stratifying the population into two BW sub-categories <1000 g and 1000-1499 g. Trend analysis was done using Cochran-Armitage test. Regression analysis was conducted to control for gestational age, race, and sex. RESULT: A total of 658,001 infants were included. SIP (n = 10,443, 1.6%) was mostly (81.9%) in the category <1000 g with 89.9% ≤28 weeks of gestation. There was a significant trend for increased SIP over the years (p < 0.001). SIP was associated with increased mortality (aOR = 2.24, CI: 2.04-2.46, p < 0.001). CONCLUSION: After controlling for gestational age and other confounders, SIP is associated with increased mortality in premature infants.
