Impact of congenital heart disease on mortality and other associated outcomes in children hospitalised for acute asthma exacerbation.

BACKGROUND: Acute asthma exacerbation is one of the most common reasons for paediatric emergency room visits and hospital admissions in the United States of America. OBJECTIVE: To assess the impact of CHD on outcomes of children hospitalised for acute asthma exacerbation. METHODS: Children primarily admitted for acute asthma exacerbation were sampled from 2006, 2009, 2012, and 2016 kid inpatient database of the Healthcare Cost and Utilization Project using ICD codes. The disease outcomes were compared between those with and without CHD using multivariate logistic regressions in Stata version 17. RESULTS: There were a total of 639,280 acute asthma exacerbation admissions, of which 5,907 (0.92%) had CHD. The mortality rate was 0.079% for patients without CHD and 0.72% for those with co-existing CHD. Children with CHD had higher odds of mortality (5.51, CI 3.40-8.93, p < 0.001), acute respiratory failure (2.84, CI 2.53-3.20; p < 0.001), need for invasive mechanical ventilation (4.58, CI 3.80-5.52; p < 0.001), acute kidney injury (adjusted odds ratio 3.03, CI 3.03-7.44; p < 0.001), and in-hospital cardiac arrest (adjusted odds ratio 4.52, CI 2.49-8.19; p < 0.001) when compared with those without CHD. The adjusted mean length of hospital stays (CI 2.91-3.91; p < 0.001) and hospital charges (95% CI $31060-$47747) among children with acute asthma exacerbation and CHD were significantly higher than in those without CHD. CONCLUSION AND SIGNIFICANCE: CHD is an independent predictor of mortality, more severe disease course, and higher hospital resource utilisation. Strategies that improve CHD care will likely improve the overall health outcomes of children with CHD hospitalised for acute asthma exacerbation.

Temporal trends and regional variation of heart transplantation in children with intellectual and developmental disabilities.

BACKGROUND: Historically, intellectual and developmental disability (IDD) has been considered an important factor in choosing potential recipients of organ transplants among many transplant centers. This study evaluated the temporal changes at the national and regional levels in the proportion of heart transplantation in children with IDD. METHODS: Children younger than 19 years in the United Network for Organ Sharing (UNOS) database who received heart transplants from 2010 to 2021 were included in this study. The patients were grouped into only definitive intellectual disability, both definitive intellectual and motor disability, only definitive motor disability, and no developmental disability. Multinomial logistic regressions were used to examine the proportion of heart transplants in each category for the whole cohort and each geographic transplant region. RESULTS: There were 4273 pediatric heart transplant recipients included in the study. From 2010 to 2021, the percentages of pediatric heart transplants increased from 3.8% (95% CI, 0.01-0.05) to 5.8% (95% CI, 0.03-0.08) in children with only definitive intellectual disability (OR 0.07; 95% CI, 0.02-0.1, ptrend < .002), from 3.4% (95% CI, 0.01-0.05) to 6.6% (95% CI, 0.04-0.09) in children with both definitive intellectual disability and motor disability (OR 0.09; 95% CI, 0.05-0.13, ptrend < .001), and from 5.2% (95% CI, 0.02-0.07) to 8.3% (95% CI, 0.05-0.1) in children with only definitive motor disability (OR 0.06; 95% CI, 0.02-0.09, ptrend < .002). There were several regional differences in the proportion of children with intellectual and developmental disabilities who received heart transplants. CONCLUSION: There is increasing inclusion of children diagnosed with intellectual and developmental disabilities in heart transplantation. A review of the current allocation policies may address the marked geographic variations found in this study.

A Descriptive Analysis of Febrile Seizure Hospitalizations in Children with Congenital Heart Disease in the United States.

BACKGROUND: Febrile seizure (FS) is the most common convulsive disorder in children. This study analyzed the national proportion of congenital heart disease (CHD) and hospital resource utilization among children admitted for FSs in the U.S. METHODS: This is a retrospective cross-sectional analysis of pediatric patients up to six years with a primary diagnosis of FS in 2016 and 2019 using the Kids Inpatient Database (KID). The demographic, hospital, and clinical characteristics of children with and without CHD were compared using the chi-square test for categorical variables and linear regressions for continuous variables. Multivariate logistic analysis was conducted to evaluate the impact of CHD on the mean length of hospital stay. RESULTS: An estimated 10,039 children were admitted with the primary diagnosis of FS. Out of these, 117 (1.2%) had a discharge diagnosis of CHD. The mean age for children with and without CHD was 1.4 years (SD 1.60) and 1.5 years (SD 1.501), respectively. Children with CHD who required hospitalization for FS had longer mean lengths of hospital stay (2.1 days vs. 1.6 days), with an adjusted odd ratio of 0.43 (95% CI: 0.07-0.99; p-value: 0.017). Similarly, the hospital charges for children with CHD were higher than those without CHD ($30,960.28 vs. $21,005.11). CONCLUSION: Children with CHD who required inpatient admission for FSs in the U.S. were associated with increased length of hospital stay and higher resource utilization when compared with those without CHD. This highlights the need for preventive measures among this vulnerable population.

Association of Adverse Childhood Experiences with Heart Conditions in Children: Insight from the 2019-2020 National Survey of Children's Health.

Adverse Childhood Experiences (ACEs) have been associated with a higher risk of developing cardiovascular diseases and premature mortality in adults. OBJECTIVES: We evaluated the associations between ACEs and heart diseases among children in the United States. METHODS: Data on children ages 0 to 17 years reported by parents/guardians to have current heart conditions were analyzed. Using Stata version 17 software, descriptive statistics were generated for the demographic characteristics and the various health outcomes using the chi-square of independence. Multivariate logistic regression models were employed to determine the associations between ACEs and heart conditions, the severity of heart conditions, and overall health status. RESULTS: There were 826 children with current heart conditions from a total of 68,753 surveyed children. This corresponded to an estimated 780,000 (1.13%) children living with heart conditions in the U.S. On multivariate logistic models, several ACEs, including household economic hardship, parental/guardian's alcohol/drug abuse, severe mental health illness of parents/guardians, racial/ethnic discrimination, exposure to neighborhood violence, and accumulation of two or more ACEs, were significantly associated with heart diseases among children. Though the accumulation of two or more ACEs did not have a significant association with the severity of heart condition, it was significantly associated with caregiver reports of undesirable overall health status. CONCLUSIONS: ACEs are significantly associated with heart conditions among children and contribute to unfavorable overall health status among children with heart conditions in the U.S. There is a need for policies and programs that will promptly identify ACEs and mitigate their negative impact on children.

Pediatric Heart Failure Inpatient Mortality: A Cross-Sectional Analysis.

Background Heart failure constitutes significant morbidity and mortality among the pediatric population. Few data exist on the prevalence and mortality rate of pediatric heart failure (pHF) in the United States. Objectives This study aimed to determine the in-hospital mortality and the principal diagnoses in pediatric patients with heart failure who died while being hospitalized in the United States. Methods This is a retrospective cross-sectional study using data from the 2019 Kid Inpatient Database (KID). The KID contained data on hospitalized children below 21 years of age. Using Stata 17 software (StataCorp LLC, College Station, Texas), the data were searched for heart failure diagnoses using International Classification of Diseases 10th revision Clinical Modification (ICD-10-CM) codes. By using the "rank" command in Stata, the most common principal diagnoses were placed in descending order of frequency, and these were further divided into different ICD-10 code categories. Results There were 16,206 pHF admissions in 2019. Of these admissions, 1,023 (6.31%) patients died. The top five principal ICD 10 code categories among all pHF deaths in descending order were circulatory system (17.95%), congenital/chromosomal abnormalities (17.43%), respiratory system (10.28%), infectious diseases (9.24%, and perinatal diseases (7.90%). Among all pHF deaths, sepsis of unspecified organisms (5.14%), hypoplastic left heart syndrome (HLHS) (3.19%), and acute respiratory failure with hypoxia (3.14%) were the most common primary diagnoses. Conclusion and significance Pediatric heart failure in-hospital overall mortality is 6.31%, and sepsis of unspecified organisms, HLHS, and acute respiratory failure are the most common principal diagnoses among these children. Preventive measures and prompt treatment of infections are paramount to reducing pHF mortality.
