Reflux disease and congenital laryngomalacia in neonates: A Kids' Inpatient Database analysis.

Congenital laryngomalacia (CLM) is the most common cause of stridor in neonates and is commonly associated with reflux disease (RD) such as gastroesophageal reflux and newborn esophageal reflux. This study investigates the impact of RD on the management and outcomes of neonates with CLM. The 2016 Kids' Inpatient Database (KID) was queried for neonates with CLM (ICD-10: Q31.5). RD status, procedures, and complications were identified with ICD-10 codes. Univariate and multivariable analyses were implemented to determine statistical associations. Of 2212 neonates identified with CLM, 585 (26.45%) had RD. Patients with RD were more often female (p = .038) and premature (p < .001). Upon multivariable analysis, patients with RD had greater total charges (Mean $457,810.87 vs. $259,020.90, p < .001) and longer length of stay (Mean 46.03 vs. 26.44 days, p < .001). Those with RD had more diagnoses recorded (Mean 14.15 vs. 9.66, p < .001), underwent more procedures (Mean 5.47 vs. 3.49, p < .001), and had a longer wait until their first procedure (Mean 13.27 vs. 7.02 days, p < .001). Patients with RD had increased odds for undergoing laryngoscopy (OR 1.799, 95% CI 1.382-2.321, p < .001), bronchoscopy (OR 2.179, 95% CI 1.598-2.801, p < .001), and ventilator use (OR 1.526, 95% CI 1.197-1.886, p < .001) on multivariable regression adjusting for patient demographics, hospital characteristics, and comorbidities. Patients with and without RD had similar odds for undergoing tracheotomy (OR 1.540, 95% CI 0.934-2.522, p = .088) and mortality (OR 1.084, 95% CI 0.397-2.646, p = .874). CLM is a common diagnosis in neonates that is associated with RD. In our cohort of neonates with CLM, those with RD had overall poorer outcomes. 4.

Risk factors and outcomes of cardiac arrest in pediatric traumatic brain injury patients.

Cardiac arrest (CA) in pediatric traumatic brain injury (pTBI) is associated with morbidity. Our objective is to investigate the incidence, risk factors, and outcomes for CA following pTBI. The Kid Inpatient Database (KID) was queried for patients with pTBI. Patients who experienced CA were identified. Demographics, comorbidities, hospital course, and complications were compared between patients who developed CA and who did not. Risk factors for CA were explored using multivariate analysis. CA patients were more likely to have hypertension, hypertrophic cardiomyopathy, and heart defects (p​<​0.01). CA was more likely in patients with subdural bleeding, cerebral edema, herniation, coma, or mechanical ventilation (p​<​0.001). CA patients had higher odds of vasopressor and transfusions, tracheostomy, percutaneous endoscopic gastrotomy (p​<​0.001), and mortality (p​<​0.01). Mechanical ventilation, cerebral edema, heart, vasopressor use, and transfusions were associated with CA on multivariate analysis. Risk factors for CA in pTBI patients include severity of injury and underlying cardiovascular abnormalities. CA was associated with morbidity and resource utilization in pTBI patients.

Epidemiology of acute pulmonary embolism in children and adolescents from nationwide US hospital data, 2016 and 2019

Abstract Background Data on the epidemiological burden and comorbidities associated with pulmonary embolism (PE) in children and adolescents is sparse. Purpose We aimed to describe the burden of acute PE in children by estimating indicators of incidence and mortality as well as the prevalence of key comorbidities in hospitalized children with (vs. without) PE. Material and methods We did a patient-level analysis of the United States Kids' Inpatient Database (KID), including patients aged 0 to 19,cumulatively for the years 2016 and 2019. PE was defined by the ICD-10 Code I26. We calculated annualized, nationwide, age-sex-specific incidence rate, mortality rate, case mortality rate, and proportionate mortality rate. Additionally, we studied the prevalence of 120 clinically selected disorders in children with vs. without acute PE. Results Acute PE was recorded in 5,738 cases (58.6% female). A total of 244 (4.3%) patients were aged 0, 214 (3.7%) aged 1-4, 206 (3.6%) aged 5-9, 677 (11.8%) aged 10-14, and 4,392 (76.5%) aged 15-19 years. The incidence rate of PE shows a J-shape curve increasing with increasing age. Proportional mortality rate paralleled the incidence rate peaking at 9.5 (95% CI: 7.3-12.3) deaths per 1,000 deaths for girls and 5.0 (4.0-6.2) deaths per 1,000 deaths for boys aged 15-19 years. In contrast, case mortality rate decreased from 33% (95% CI: 24.8-42.4) among girls and 15.9% (95% CI: 10.8-23) among boys in the first year of age to 2.1% (95% CI: 1.6-2.7) among girls and 4.5% (95% CI: 3.6-5.6) among boys aged 15-19. Table 1 presents key age-sex stratified epidemiologic indicators. The highest absolute prevalence difference (APD) between those with vs. without PE was found for venous thrombosis (APD: 31.8%, 95% CI: 30.6-33), followed by metabolic disorders (APD: 15.2%, 95% CI: 14-16.5) and obesity (APD: 14.7%, 95% CI: 13.7-15.8). Figure 1 presents an overview of the APD of clinically selected disorders in patients with vs. without PE. Conclusion This comprehensive overview shows that the burden of PE among children and adolescents is considerable, but with considerable variation across age classes and co-occurrence with different specific comorbidities.Table 1.Figure 1.

Obstructive Sleep Apnea Is Associated with Worsened Hospital Outcomes in Children Hospitalized with Asthma.

Studies have shown a bidirectional relationship between asthma and obstructive sleep apnea (OSA). However, there is a paucity of national-level data evaluating the impact of OSA on hospital outcomes in pediatric hospitalizations for asthma. We analyzed the National Inpatient Sample and Kids Inpatient Database to include all pediatric hospitalizations with a primary diagnosis of asthma between 2003-2016. Using ICD codes, the pediatric asthma cohort was divided into two groups: those with and those without a concomitant diagnosis of OSA. The primary outcomes were in-hospital mortality and the need for mechanical ventilation. The secondary outcomes were the lengths of each hospital stay and total hospitalization charges. We analyzed 1,606,248 hospitalizations during the 14-year study period. The overall prevalence rate of OSA was 0.7%. Patients with asthma and OSA were significantly older (8.2 versus 5.9 years) and were more often male, p < 0.001. The OSA group had several increased comorbidities. The overall mortality rate was 0.03%, and multivariate regression analysis showed that OSA was associated with 4.3 times higher odds of in-hospital mortality (95% CI: 2.4 to 7.6, p < 0.001). Furthermore, OSA was associated with a 5.2 times greater need for mechanical ventilation (95% CI: 4.8 to 5.5, p < 0.001). Linear regression analyses demonstrated that OSA independently contributed an additional 0.82 days to the hospital stay length (95% CI: 0.79 to 0.86, p < 0.001) and an extra 10,479 USD (95% CI: 10,110 to 10,848, p < 0.001) in hospitalization charges. OSA in children admitted with asthma is associated with poor hospital outcomes such as increased mortality risk, the need for mechanical ventilation, and increased healthcare utilization.

Discrepancies in pediatric OSA surgery hospital stay length across regions

ObjectiveTo investigate regional disparities in the length of hospital stay (LOS) for pediatric patients undergoing tonsillectomy for obstructive sleep apnea (OSA) in the United States. MethodsWe utilized the Healthcare Cost and Utilization Project (HCUP) Kid Inpatient Database (KID) for 2016, analyzing data on pediatric OSA patients aged 0–20. We compared LOS in different U.S. regions and employed statistical tests to assess significance. ResultsRegional variation in LOS was observed among pediatric OSA patients. The Midwest and South regions showed longer LOS compared to the West and Northeast. Notably, standard deviations for LOS in the Midwest and South were substantial, signifying significant variability. ConclusionOur findings emphasize the importance of addressing regional differences in pediatric OSA care. Prolonged hospital stays can impose significant burdens on children and families. Identifying and mitigating factors driving these disparities is crucial for enhancing the quality and efficiency of care, ultimately striving for more equitable healthcare for pediatric OSA patients nationwide.

Understanding pediatric inpatient conductive hearing loss: An analysis of patient demographics

ObjectiveHearing loss is a common sensory impairment in children that affects quality of life and development. Early intervention, such as hearing aids and communication therapies, can help children overcome these challenges and lessen the impact on their development. The objective of this study was to identify specific patient demographic factors correlated with the prevalence of pediatric conductive hearing loss. Study designThe study utilized the Kids' Inpatient Database (KID) by the Agency for Healthcare Research and Quality which collects inpatient information from hospitals for patients under 21 years old. We included all patients discharged in 2016 diagnosed with conductive hearing loss, and excluded neonatal patients discharged within 28 days of birth. MethodsStatistical analyses were performed using R Studio and IBM SPSS Statistics. Weighted odds ratios were calculated for conductive hearing loss in relation to race and income, and a multivariate regression analysis examined associations between demographic variables and race categories in conductive hearing loss. ResultsThe prevalence of conductive hearing loss (CHL) in pediatric patients in 2016 was 51.62 cases per 100,000 patients. Non-Hispanic White patients had the highest prevalence, while Black patients had the highest likelihood of CHL compared to the overall population. Lower income levels were associated with a decreased probability of CHL diagnosis. After adjusting for age, sex, hospital region, insurance, and income on multivariate analysis, White and Black patients were less likely to be diagnosed with CHL. Furthermore, patients in specific income quartiles also had lower CHL likelihood compared to the general population. ConclusionWhile Black patients had a higher likelihood of being diagnosed with CHL than the general population, socioeconomic factors such as income greatly influenced the likelihood of CHL diagnosis. Other significant factors included income, region of the country, sex, and age. Further research is needed to better understand and address healthcare disparities related to pediatric hearing loss.

Hospital and Patient Characteristics Associated with Neonatal Blood Stream Infection in Inpatient Care: Insights from the 2019 HCUP KID Database.

This study explores the associations between pediatric adverse events (PAEs) and both hospital and patient characteristics within the inpatient hospital setting, specifically focusing on Neonatal Blood Stream Infection (NBSI) as defined by pediatric quality indicators (PDIs) from the Agency for Healthcare Research and Quality (AHRQ). This research aims to answer questions regarding the relationship between hospital characteristics and patient demographics with the occurrence of NBSI. This study utilized discharge data from the Healthcare Cost and Utilization Project (HCUP) Kids' Inpatient Databases (KID) for the year 2019. Bivariate and multivariate logistic regression models were employed to analyze patient-level encounters of NBSIs. The analysis examined various factors including hospital size, location, and teaching status, as well as patient-specific variables such as gender, age, race, service lines, payment sources, and major operating room procedures. The results indicate that Public and Private not-for-profit hospitals showed significantly lower odds of experiencing NBSIs when compared to Private investor-owned hospitals, as did smaller, rural, and nonteaching hospitals when compared to large hospitals. Additionally, individual factors such as gender, age, race, service lines, payment sources, and types of major operating room procedures were found to have varying levels of significance in relation to NBSI. This study provides important insights into PAEs within the inpatient hospital setting, particularly focusing on NBSIs within the PDI framework. The findings highlight critical areas for the development of evidence-based interventions and guidelines, which are essential for clinicians and policymakers. Ultimately, this study contributes to the understanding and improvement of pediatric patient safety by emphasizing the necessity for targeted strategies to mitigate the risk of NBSI.

Epidemiology, Outcomes, and Trend Analysis of Hospitalized Infants With Respiratory Syncytial Virus (RSV) Bronchiolitis From 1997 to 2019.

Background Most children with respiratory syncytial virus (RSV) infection have a self-limiting course that can be managed with supportive care, and hospitalization is uncommon. The objectives of this study were to evaluate the epidemiology, outcomes, associated comorbidities, and temporal trends in the prevalence of infants one to 24 months of age who required hospitalization for RSV infection in the United States of America from 1997 to 2019. Methods In this retrospective cross-sectional study, we utilized the Kids' Inpatient Database (KID) to investigate the prevalence and outcomes of RSV bronchiolitis within a large cohort of discharged patients from 1997 to 2019. We included children one to 24 months of age admitted with a diagnosis of RSV bronchiolitis. Neonates were excluded from the analysis. A chi-square for linear trend was used to analyze trends in the prevalence of RSV bronchiolitis hospitalization, the presence of complex chronic conditions (CCC), congenital heart disease (CHD), the use of non-invasive and invasive mechanical ventilation (NIV and IMV), and hospital mortality. Results There were a total of 566,786 infants aged one to 24 months hospitalized with RSV infection out of a total of 9,309,597 discharges during the eight-year cohort, with a hospital prevalence of 60.9 per 1000 discharges and a hospital mortality rate of 0.09% (95% confidence interval (CI): 0.08%-0.1%). There was no trend in hospitalization rates of RSV infections per 100,000 U.S. population during the study period, with a decrease in hospital mortality trend. Children with RSV bronchiolitis were more likely to have government insurance and reside in zip codes with the lowest income quartile. There was a significant seasonal and regional variation in RSV-related hospitalizations. The presence of CCC was identified in 2.4% of the RSV group compared to 5.1% of non-RSV discharges (odds ratio (OR): 0.46, 95% CI: 0.45-0.47; p<0.001). The prevalence of RSV among all discharges has significantly increased over the study period, rising from 51.6 cases per 1000 discharges in 1997 to 180.1 cases per 1000 discharges in 2019 (p<0.001). The prevalence of CCC and CHD among RSV patients has also shown an upward trend, with CCC cases increasing from 1,411 in 1997 to 2,795 in 2019 and CHD cases rising from 1,795 to 3,622 during the same period. The use of invasive mechanical ventilation, non-invasive ventilation, and extracorporeal membrane oxygenation has consistently increased over time. Additionally, complications such as the need for cardiopulmonary resuscitation have demonstrated a similar increasing trend, although they have remained overall low. However, population-based hospitalization rates showed no significant trend. Conclusions The hospitalization rates at a population level in the United States for RSV infection in children aged one to 24 months remained steady from 1997 to 2019, while hospital mortality rates showed a declining trend. There is an increased proportion of comorbid conditions and increased resource utilization in children with RSV. These findings are important for monitoring the effectiveness of preventive strategies for severe RSV infections.

Factors influencing disparities in epilepsy surgery: analysis of the National Inpatient Sample and Kids' Inpatient Database.

Despite the proven efficacy of surgical intervention for achieving seizure freedom and improved quality of life for many epilepsy patients, this treatment remains underutilized. In this study, the authors assessed sociodemographic trends in epilepsy surgery in the National Inpatient Sample (NIS) and the Kids' Inpatient Database (KID) and sought to determine whether disparities in surgical intervention for epilepsy may be attributed to insurance and comorbidity status. This cross-sectional study utilized data from the NIS database and KID from the Healthcare Cost and Utilization Project between the years 2012 and 2018. Outcomes of interest were rates of neurosurgical intervention, including resection, neuromodulation, or laser ablation. The authors utilized logit regression models to test the association between rates of neurosurgical intervention and the variables of interest and calculated the adjusted mean proportion of patients who received surgery using marginal effects. Of 336,015 admissions with intractable epilepsy in the NIS, 6.1% were patients who underwent neurosurgical treatment. Of 39,655 admissions from KID, 5.0% received surgical treatment. Private insurance was associated with a greater odds of surgical intervention compared with Medicaid (NIS: OR 1.63, KID: OR 1.62; p < 0.001). Patients assigned White race had an increased odds ratio of undergoing surgery when compared with those assigned Black race, adjusted for comorbidity burden (NIS: OR 1.59, p < 0.001; KID: OR 1.44, p = 0.027). Patients with an Elixhauser Comorbidity Index score of 0 or 1 were associated with a lower likelihood of surgery when compared to their higher scoring counterparts who had 4 or more comorbidities (NIS: OR 0.74, KID: OR 0.62; both p < 0.001). This study demonstrates that marginalized patients and those with Medicaid had decreased odds of neurosurgical intervention for epilepsy. Results of this research support the need for increased attention toward epilepsy patients from marginalized groups. Further investigation into the root cause of socioeconomic inequities in epilepsy surgery is necessary.

Assessing national trends in indications for pediatric total thyroidectomy

PurposeThe most common indications for total thyroidectomy (TT) in children are malignancy and thyrotoxicosis due to Graves' disease (GD). However, the incidence of patients with GD among patients undergoing TT is unknown. This study aims to examine trends in pediatric TT. Materials and methodsThe US Agency for Health Research and Quality Healthcare Cost and Utilization Project (HCUP) Kids' Inpatient Database (KID) was queried to identify patients who underwent TT between 1997 and 2019. Weighted national estimates were obtained. Statistical analysis was completed using univariate logistic regression and one-sided Mann-Kendall Test. ResultsAn estimated 4803 pediatric patients underwent TT within the study years. GD was the indication in 25 % of cases. Mann-Kendall testing showed a trend toward an increasing proportion of TT for GD without reaching statistical significance (z = 1.3609, S = 12, p = 0.0688). Statistically significant univariate associations were found among those who underwent thyroidectomy for GD compared to other indications, as they were more likely to be female (β = 0.286, 95 % CI [0.058, 0.514], p = 0.014), Black, or Hispanic (β = 1.392 [1.064, 1.721], p < 0.001; and β = 0.562 [0.311, 0.814], p < 0.001, respectively). Additionally, they were less likely to have private insurance (β = −0.308 [−1.076, −0.753], p = 0.002) and more likely to live in a ZIP code associated with a median household income below the 50th percentile (β = 0.190 [0.012, 0.369], p = 0.036). The associations with the female sex, Black race, and Hispanic race persisted in multivariate analysis. ConclusionGD appears to be an increasingly prevalent indication for TT. Patient characteristics differ from those who undergo TT for other diagnoses.

Tracheostomy and inpatient outcomes among children with congenital central hypoventilation syndrome: A kids' inpatient database study.

Congenital central hypoventilation syndrome (CCHS) is a rare disease predisposing children to respiratory failure due to abnormal ventilatory drive. Variability in hypoventilation and respiratory support need have been reported. We aim to identify clinical variables associated with incident tracheostomy and common etiologies of hospitalization among children with CCHS. Hospital discharge records were obtained for children (<21 years) with CCHS hospitalized between 2006 and 2019 from the Kid's Inpatient Database. Primary diagnostic categories for hospitalizations with CCHS were summarized. Multivariable logistic regression models were used to explore risk factors associated with incident tracheostomy. Among 2404 hospitalizations with CCHS, 133 (5.5%) had incident tracheostomy, 1230 (51.2%) had established tracheostomy, and 1041 (43.3%) had no tracheostomy. Compared with children without tracheostomy, those with incident tracheostomy were younger, had a history of prematurity, congenital heart disease, laryngeal, glottic, and subglottic stenosis (LGSS), congenital airway anomalies, neuromuscular weakness, gastroesophageal reflux disease. Children without tracheostomy had higher mortality than those with tracheostomy status (2.19% vs. 0.66%). Multivariable-adjusted analyses showed that incident tracheostomy was associated with infancy (0-1 years), neuromuscular weakness, and congenital heart disease. Most common diagnostic categories include (1) diseases of the respiratory system (30.23%), (2) injury and poisoning (9.35%), and (3) diseases of the nervous system and sense organs (6.71%). Children with CCHS who received incident tracheostomy are more likely to be younger and with LGSS, neuromuscular weakness and congenital heart disease. Clinicians should be aware of these risk factors representing more severe CCHS with earlier manifestation needing tracheostomy. Higher mortality among nontracheostomy group highlights the need for considering tracheostomy in caring for children with CCHS.

National Trends in Inpatient Hospital Outcomes of Children with Osteogenesis Imperfecta and the Importance of Extraskeletal Manifestations: A Kids’ Inpatient Database Study

ObjectiveTo investigate the extent of extra-skeletal manifestations along with inpatient outcomes and complications associated with osteogenesis imperfecta (OI). Study designThis cross-sectional study utilized the Kids’ Inpatient Database (KID) as part of the Healthcare Cost and Utilization Project (HCUP) to investigate inpatient hospital outcomes and management in patients with OI from 1997 through 2016. Data regarding hospital characteristics, cost of treatment, inpatient outcomes, and procedures were collected and analyzed. ResultsThere were 7,291 admissions that listed OI as a diagnosis in the KID database from 1997 through 2016. Unexpectedly, over one third of all admissions in these children with OI presented with an extra-skeletal manifestation. The rate of major complications was 3.85%. The rate of minor complications was 19.4%, most commonly respiratory problems. Mortality rate was 18.2 % in the neonatal period and 1.0% in all other admissions. Total charges of hospital stay increased over the years. ConclusionWe identified a striking prevalence of extra-skeletal manifestations in OI along with inpatient outcomes and complications associated with OI, of which respiratory complications were predominant. We observed a significant financial burden for patients with OI and identified additional risks for financial crisis, in addition to disparities in care identified among socioeconomic groups. These data contribute to a more holistic understanding of OI from diagnosis to management.

Risk Factors for Pediatric Intracranial Neoplasms in the Kids’ Inpatient Database

Introduction: In children and adolescents, brain and central nervous system (CNS) tumors are the leading types of cancers. Past studies have found differing rates of intracranial cancers among races and identified additional cancer risk factors. This study aimed to see if these differences can be substantiated with further investigation of the latest version (2019) of the Kids’ Inpatient Database (KID). Methods: A total of 7,818 pediatric patients <21 years old in KID with ICD-10 codes consisting of malignant neoplasms of the brain, brainstem, and cerebral meninges (C700, C709–C719) were queried. Modifiable risk factors evaluated include: hospital region, insurance type, hospital city size, the average income of patient zip code, and location/teaching status of a hospital. Non-modifiable risk factors were race and sex at birth. Dependent variables were tested in Excel and GraphPad Prism 9 using a χ2 test with Yates’ continuity correction and Tukey’s one-way and two-way ANOVAs. Results: Mortality rates of females (2.88%) compared to males (1.99%) were significant (p < 0.05). Mortality was (4.17%) in black patients compared to (1.68%) for white (p < 0.0001), Hispanic mortality (2.95%) compared to white (p < 0.01), and mortality of Asian/Pacific Islander (3.86%) compared to white (p < 0.01). Black patients had significantly higher mortality than white, Hispanic, Asian/Pacific Islander, Native American, and other races overall (p < 0.01). There was no significant difference in the mortality rates between children’s hospitals and large hospitals for any race. After accounting for patient race, mortality was still not significantly different for patients with Medicaid insurance compared to non-Medicaid insurance types. Of the children treated at children’s hospitals, the most transferred in from outside hospitals were Native American (20.00%) followed by Asian/Pacific Islander (15.09%) then Hispanic patients (13.67%). A significant difference between races was also seen regarding length of stay (p < 0.001) and number of charges (p < 0.001). Conclusion: These findings confirm prior studies suggesting gender and race are significant factors in mortality rates for children with intracranial neoplasms. However, the findings do not identify the root causes of these discrepancies but may serve as an impetus for clinicians, healthcare administrators, and governmental leaders to improve national resource allocation to better care for pediatric patients with intracranial neoplasms.

Factors influencing hospital charges for tonsillectomy to treat obstructive sleep apnea in children.

This study investigates the impact of patient characteristics and demographics on hospital charges for tonsillectomy as a treatment for pediatric obstructive sleep apnea (OSA). The aim is to identify potential disparities in hospital charges and contribute to efforts for equitable access to care. Data from the 2016 Healthcare Cost and Utilization Project (HCUP) Kid Inpatient Database (KID) was analyzed. The sample included 3,304 pediatric patients undergoing tonsillectomy ± adenoidectomy for OSA. Variables such as age, race, length of stay, hospital region, residential location, payer information, and median household income were collected. The primary outcome variable was hospital charge. Statistical analyses, including t-tests, ANOVA, and multiple linear regression, were conducted. Among 3,304 pediatric patients undergoing tonsillectomy for OSA. The average total charges for tonsillectomy were $26,400, with a mean length of stay of 1.70 days. Significant differences in charges were observed based on patient race, hospital region, and payer information. No significant differences were found based on gender, discharge quarter, residential location, or median household income. Multiple linear regression showed race, hospital region, and residential location were significant predictors of total hospital charges. This study highlights the influence of patient demographics and regional factors on hospital charges for pediatric tonsillectomy in OSA cases. These findings underscore the importance of addressing potential disparities in healthcare access and resource allocation to ensure equitable care for children with OSA. Efforts should be made to promote fair and affordable treatment for all pediatric OSA patients, regardless of their demographic backgrounds.

Pediatric Physical Restraint Coding in US Hospitals: A 2019 Kids Inpatient Database Study.

Reduction of physical restraint utilization is a goal of high-quality hospital care, but there is little nationally-representative data about physical restraint utilization in hospitalized children in the United States. This study reports the rate of physical restraint coding among hospitalizations for patients aged 1 to 18 years old in the United States and explores associated demographic and diagnostic factors. The Kids' Inpatient Database, an all-payors database of community hospital discharges in the United States, was queried for hospitalizations with a diagnosis of physical restraint status in 2019. Logistic regression using patient sociodemographic characteristics was used to characterize factors associated with physical restraint coding. A coded diagnosis of physical restraint status was present for 8893 (95% confidence interval [CI]: 8227-9560) hospitalizations among individuals aged 1 to 18 years old, or 0.63% of hospitalizations. Diagnoses associated with physical restraint varied by age, with mental health diagnoses overall the most frequent in an adjusted model, male sex (adjusted odds ratio [aOR] 1.56; 95% CI: 1.47-1.65), Black race (aOR 1.43; 95% CI: 1.33-1.55), a primary mental health or substance diagnosis (aOR 7.13; 95% CI: 6.42-7.90), Medicare or Medicaid insurance (aOR 1.33; 95% CI: 1.24-1.43), and more severe illness (aOR 2.83; 95% CI: 2.73-2.94) were associated with higher odds of a hospitalization involving a physical restraint code. Physical restraint coding varied by age, sex, race, region, and disease severity. These results highlight potential disparities in physical restraint utilization, which may have consequences for equity.

Temporal trends of splenectomy in pediatric hospitalizations with hereditary spherocytosis from 2000 to 2019: A national survey.

Total and partial splenectomy are used in pediatric patients with hereditary spherocytosis to resolve anemia and hemolytic complications. Data from the Healthcare Cost and Utilization Project's Kid's Inpatient Database was used to profile and describe temporal trends in pediatric (≤18years) hospital admissions in the United States from 2000 to 2019 data release years. Survey sampling methods were used to produce national estimates. From 2000 to 2019, the use of splenectomy declined overall, from 427 to 206 weighted procedures (difference=222, 95% confidence interval [CI]: 124-320; p<.0001); the risk of undergoing splenectomy during admission also declined from 56.7% to 38.7% (risk difference=17.9 percentage points [p.p.], 95% CI: 9.7-26.1; p<.0001). Total splenectomy was mostly used. Age at time of splenectomy increased 10.2years (difference=1.6years, 95% CI: 0.6-2.7; p=.0018). The risk of splenectomy increased with age until 10years, then leveled off until 18years. The proportion of children aged ≤5years undergoing splenectomy decreased from 27.7% to 11.2% in 2019 (risk difference: 16.5 p.p., 95% CI: 7.3-25.7; p=.0004). The strongest clinical predictors of splenectomy, adjusting for patient- and hospital-level characteristics, were a co-diagnosis of symptomatic cholelithiasis (adjusted odds ratio [aOR]=3.18, 95% CI: 1.92-5.28; p<.0001) and splenomegaly or hypersplenism (aOR=2.52, 95% CI: 1.74-3.65; p<.0001). Risk of splenectomy with splenomegaly or hypersplenism increased over time. Splenectomy was delayed until age greater than 10years. Older age, co-diagnosis with splenomegaly or hypersplenism, or symptomatic cholelithiasis were strongest clinical predictors of splenectomy. Conservative management of hereditary spherocytosis appears to be more common.

Preterm Labor and Hypertensive Disorders in Adolescent Pregnancies With Diabetes Between 2006 and 2019

Objective: We sought to evaluate the risk of preterm labor and hypertensive disorders in adolescent pregnancies with and without diabetes.Methods: We evaluated 1,843,139 adolescents (≤20 years old) with labor and delivery admissions in the national Kids’ Inpatient Database (KID) in years 2006, 2009, 2012, 2016, and 2019. International classification of disease codes was used to identify diabetes and medical factors affecting pregnancy. Weighted logistic regression was used to evaluate the association between diabetes and complications.Results: Among admissions, 0.2% had type 1 diabetes (T1D), 0.2% had type 2 diabetes (T2D), and 0.7% had gestational diabetes (GDM); 10.1% of admissions were complicated by hypertensive disorders and 5.8% by preterm labor. Compared to adolescents without diabetes, those with diabetes had a higher prevalence of hypertensive disorders (T1D: 35.4%, T2D: 37.8%, GDM: 24.9%, None: 9.9%; p &lt; 0.001) and preterm labor (T1D: 21.5%, T2D: 16.8%, GDM: 6.8%, none: 5.7%; p &lt; 0.001). In adjusted models, odds of hypertensive disorders were higher in later study years (2019 vs. 2006 OR 1.85, 95% CI 1.77–1.94), among those with T1D (OR 4.32, 95% CI 3.94–4.74), with T2D (OR 4.18, 95% CI 3.79–4.61), and with GDM (OR 1.99, 95% CI 1.89–2.10). Adjusted odds of preterm labor were higher among those with T1D (OR 4.53, 95% CI 4.09–5.02), with T2D (OR 3.35, 95% CI 2.96–3.78), and with GDM (OR 1.18, 95% CI 1.08–1.28); disparities were seen by race/ethnicity, insurance, and income.Conclusions: Diabetes, which is increasing among adolescents, is a significant risk factor for preterm labor and hypertensive disorders. Though the absolute number of adolescent pregnancies is decreasing, rates of hypertensive disorders have increased. Appropriate interventions are needed to ensure healthy outcomes for adolescents who are pregnant.

Associations between Hospital Setting and Outcomes after Pediatric Appendectomy.

Prior studies of associations between hospital location and outcomes for pediatric appendectomy have not adjusted for significant differences in patient and treatment patterns between settings. This was a cross-sectional analysis of pediatric appendectomies in the 2016 Kids' Inpatient Database (KID). Weighted multiple linear and logistic regression models compared hospital location (urban or rural) and academic status against total admission cost (TAC), length of stay (LOS), and postoperative complications. Patients were stratified by laparoscopic (LA) or open (OA) appendectomy. Among 54,836 patients, 39,454 (73%) were performed at an urban academic center, 11,642 (21%) were performed at an urban non-academic center, and 3740 (7%) were performed at a rural center. LA was utilized for 49,011 (89%) of all 54,386 patients: 36,049 (91%) of 39,454 patients at urban academic hospitals, 10,191 (87%) of 11,642 patients at urban non-academic centers, and 2771 (74%) of 3740 patients at rural centers (p < 0.001). On adjusted analysis, urban academic centers were associated with an 18% decreased TAC (95% CI -0.193--0.165; p < 0.001) despite an 11% increased LOS (95% CI 0.087-0.134; p < 0.001) compared to rural centers. Urban academic centers were associated with a decreased odds of complication among patients who underwent LA (OR 0.787, 95% CI 0.650-0.952) but not after OA. After adjusting for relevant patient and disease-related factors, urban academic centers were associated with lower costs despite longer lengths of stay compared to rural centers. Urban academic centers utilized LA more frequently and were associated with decreased odds of postoperative complications after LA.

Variation in Length of Stay by Level of Neonatal Care Among Moderate and Late Preterm Infants.

Moderate and late preterm infants are a growing subgroup of neonates with increased care needs after birth, yet standard protocols are lacking. We aim to describe variation in length of stay (LOS) by gestational age (GA) across hospitals within the same level of neonatal care and between different levels of neonatal care. Retrospective cohort study of hospitalizations for moderate (32-33 weeks GA) and late (34-36 weeks GA) preterm infants in 2019 Kid's Inpatient Database. We compared adjusted LOS in this cohort and evaluated variation within hospitals of the same level and across different levels of neonatal care. This study includes 217 051 moderate (26.2%) and late (73.8%) preterm infants from level II (19.7%), III (66.3%), and IV (11.1%) hospitals. Patient-level (race and ethnicity, primary payor, delivery type, multiple gestation, birth weight) and hospital-level (birth region, level of neonatal care) factors were significantly associated with LOS. Adjusted mean LOS varied for hospitals within the same level of neonatal care with level II hospitals showing the greatest variability among 34- to 36- week GA infants when compared with level III and IV hospitals (P < .01). LOS also varied significantly between levels of neonatal care with the greatest variation (0.9 days) seen in 32-week GA between level III and level IV hospitals. For moderate and late preterm infants, the level of neonatal care was associated with variation in LOS after adjusting for clinical severity. Hospitals providing level II neonatal care showed the greatest variation and may provide an opportunity to standardize care.

Mechanical circulatory support in pediatric myocarditis: Support strategies and outcomes in a nationally representative cohort

Myocarditis is a common cause of pediatric heart failure which may require mechanical circulatory support (MCS). The purpose of this study is to describe MCS strategies used in a nationwide cohort of pediatric patients with myocarditis, identify trends over time, and compare outcomes between MCS strategies. This study utilized the Kids' Inpatient Database (KID), a national sample of administrative discharge data. KID admissions from 2003-2016 were queried using ICD-9/10 codes to identify those with a diagnosis of myocarditis. MCS outcomes were compared using logistic regression. Of 5,661 admissions for myocarditis, MCS was used in 424 (7.5%), comprised of extracorporeal membrane oxygenation (ECMO) in 312 (73.6%), including 32 (10.2%) instances of extracorporeal cardiopulmonary resuscitation (ECPR), temporary ventricular assist devices (tVAD) in 28 (6.6%), durable VAD (dVAD) in 42 (9.9%) and combination MCS in 42 (9.9%). MCS use increased over time (p=0.031), but MCS strategies did not significantly change. Mortality was high in the MCS group (28.3%). There was no difference in odds of death in the VAD only or combination MCS group compared to the non-ECPR ECMO group (p=0.07 and p=0.65, respectively). MCS is used in 1 in 13 pediatric myocarditis cases, and MCS use is increasing over time with ECMO remaining the most frequently used modality. Mortality remains high in patients that receive MCS but does not differ between those receiving VAD or combination MCS as compared to non-ECPR ECMO on unadjusted analysis. Further prospective analysis is required to evaluate the relative effectiveness of MCS modalities in this disease.
