Pediatric complex chronic conditions classification system version 2: updated for ICD-10 and complex medical technology dependence and transplantation

National Characteristics of Emergency Care for Children with Neurologic Complex Chronic Conditions

Introduction

Most pediatric emergency care occurs in general emergency departments (GED), where less pediatric experience and lower pediatric emergency readiness may compromise care. Medically vulnerable pediatric patients, such as those with chronic, severe, neurologic conditions, are likely to be disproportionately affected by suboptimal care in GEDs; however, little is known about characteristics of their care in either the general or pediatric emergency setting. In this study our objective was to compare the frequency, characteristics, and outcomes of ED visits made by children with chronic neurologic diseases between general and pediatric EDs (PED).

Methods

We conducted a retrospective analysis of the 2011-2014 Nationwide Emergency Department Sample (NEDS) for ED visits made by patients 0-21 years with neurologic complex chronic conditions (neuro CCC). We compared patient, hospital, and ED visits characteristics between GEDs and PEDs using descriptive statistics. We assessed outcomes of admission, transfer, critical procedure performance, and mortality using multivariable logistic regression.

Results

There were 387,813 neuro CCC ED visits (0.3% of 0-21-year-old ED visits) in our sample. Care occurred predominantly in GEDs, and visits were associated with a high severity of illness (30.1% highest severity classification score). Compared to GED visits, PED neuro CCC visits were comprised of individuals who were younger, more likely to have comorbid conditions (32.9% vs 21%, P < 0.001), and technology assistance (65.4% vs. 45.9%) but underwent fewer procedures and had lower ED charges ($2,200 vs $1,520, P < 0.001). Visits to PEDs had lower adjusted odds of critical procedures (adjusted odds ratio [aOR] 0.74, 95% confidence interval [CI] 0.62-0.87), transfers (aOR 0.14, 95% CI 0.04-0.56), and mortality (aOR 0.38, 95% CI 0.19-0.75) compared to GEDs.

Conclusion

Care for children with neuro CCCs in a pediatric ED is associated with less resource utilization and lower rates of transfer and mortality. Identifying features of PED care for neuro CCCs could lead to lower costs and mortality for this population.

Performance of Febrile Infant Decision Tools on Hypothermic Infants Evaluated for Infection

BACKGROUND

Given the lack of evidence-based guidelines for hypothermic infants, providers may be inclined to use febrile infant decision-making tools to guide management decisions. Our objective was to assess the diagnostic performance of febrile infant decision tools for identifying hypothermic infants at low risk of bacterial infection.

METHODS

We conducted a secondary analysis of a retrospective cohort study of hypothermic (≤36.0 C) infants ≤90 days of age presenting to the emergency department or inpatient unit among 9 participating sites between September 1, 2016 and May 5, 2021. Well-appearing infants evaluated for bacterial infections via laboratory testing were included. Infants with complex chronic conditions or premature birth were excluded. Performance characteristics for detecting serious bacterial infection (SBI; urinary tract infection, bacteremia, bacterial meningitis) and invasive bacterial infection (IBI; bacteremia, bacterial meningitis) were calculated for each tool.

RESULTS

Overall, 314 infants met the general inclusion criteria, including 14 cases of SBI (4.5%) and 7 cases of IBI (2.2%). The median age was 5 days, and 68.1% of the infants (214/314) underwent a full sepsis evaluation. The Philadelphia, Boston, IBI Score, and American Academy of Pediatrics Clinical Practice Guideline did not misclassify any SBI or IBI as low risk; however, they had low specificity and positive predictive value. Rochester and Pediatric Emergency Care Applied Research Network tools misclassified infants with bacterial infections.

CONCLUSIONS

Several febrile infant decision tools were highly sensitive, minimizing missed SBIs and IBIs in hypothermic infants. However, the low specificity of these decision tools may lead to unnecessary testing, antimicrobial exposure, and hospitalization.

Current Inpatient Screening Practices for Sexual History and STIs: An Opportunity to Seize

The American Academy of Pediatrics recommends utilizing hospitalizations as an opportunity to provide sexual health screenings for adolescents. This study aimed to describe the current practice of sexual history documentation (SHxD) and sexually transmitted infection (STI) testing among adolescents admitted to a pediatric hospital medicine service. Retrospective cross-sectional study of adolescents (14-19 years old) admitted to the PHM service from 2017-2019 was performed at an academic children's health system. Patient (demographics, history of complex chronic condition, and insurance), hospitalization (length of stay, diagnosis, STI tests ordered/results), and physician (level of training and gender) characteristics were extracted for each encounter. A natural language processing algorithm identified the presence of SHxD. Univariate analysis and multivariable analysis were performed to detect factors associated with SHxD and STI screening. The prevalence of STIs was calculated for those who were tested. Out of 2242 encounters, SHxD and STI testing rates were 40.9% and 17.2%, respectively. Patient gender, race, lack of complex chronic condition, and resident involvement were predictive of SHxD and STI testing. SHxD increased the odds of STI testing significantly (OR 5.06, CI 3.90-6.58). Among those who were tested, the prevalence of STIs was highest for chlamydia (37/329, 11.2%). Overall, sexual health screening rates remain low in the hospital setting and future improvement initiatives are needed.

Comparison of actigraphy with a sleep protocol maintained by professional caregivers and questionnaire-based parental judgment in children and adolescents with life-limiting conditions

BACKGROUND

Actigraphy offers a promising way to objectively assess pediatric sleep. Aim of the study was investigating the extent to which actigraphy used in children and adolescents with life-limiting conditions is consistent with two other measures of sleep diagnostics.

METHODS

In this monocentric prospective study N = 26 children and adolescents with life-limiting conditions treated on a pediatric palliative care unit were assessed. For three consecutive nights they wore an actigraph; the 24-hours sleep protocol documented by nurses and the Sleep Screening for Children and Adolescents with Complex Chronic Conditions (SCAC) answered by parents were analyzed. Patient characteristics and the parameters sleep onset, sleep offset, wake after sleep onset (WASO), number of wake phases, total sleep time (TST) and sleep efficiency (SE) were descriptively examined. Percentage bend correlations evaluated the three measures' concordance.

RESULTS

Descriptively, and except for the number of waking episodes, the different measures' estimations were comparable. Significant correlations existed between actigraphy and the sleep protocol for sleep onset (r = 0.83, p = < 0.001) and sleep offset (r = 0.89, p = < 0.001), between actigraphy and SCAC for SE (r = 0.59, p = 0.02).

CONCLUSION

Agreement of actigraphy with the focused sleep measures seems to be basically given but to varying degrees depending on the considered parameters.

Representation of the hierarchical and functional structure of an ambulatory network of medical consultations through Social Network Analysis, with an emphasis on the role of medical specialties

BACKGROUND

Ambulatory Health Care Networks (Amb-HCN) are circuits of patient referral and counter-referral that emerge, explicitly or spontaneously, between doctors who provide care in their offices. Finding a meaningful analytical representation for the organic and hierarchical functioning of an Amb-HCN may have managerial and health policymaking implications. We aimed to characterize the structural and functional topology of an Amb-HCN of a private health insurance provider (PHIP) using objective metrics from graph theory.

METHODS

This is a cross-sectional quantitative study with a secondary data analysis study design. A Social Network Analysis (SNA) was conducted using office visits performed between April 1, 2021 and May 15, 2022, retrieved from secondary administrative claim databases from a PHIP in Belo Horizonte, Southeastern Brazil. Included were beneficiaries of a healthcare plan not restricting the location or physician caring for the patient. A directional and weighted network was constructed, where doctors were the vertices and patient referrals between doctors, within 7-45 days, were the network edges. Vertex-level SNA measures were calculated and grouped into three theoretical constructs: patient follow-up (aimed at assessing the doctor's pattern of patient follow-up); relationship with authorities (which assessed whether the doctor is an authority or contributes to his or her colleague's authority status); and centrality (aimed at positioning the doctor relative to the network graph). To characterize physician profiles within each dimension based on SNA metrics results, a K-means cluster analysis was conducted. The resulting physician clusters were assigned labels that sought to be representative of the observed values of the vertex metrics within the clusters.

FINDINGS

Overall, 666,263 individuals performed 3,863,222 office visits with 4,554 physicians. A total of 577 physicians (12.7%) had very low consultation productivity and contributed very little to the network (i.e., about 1.1% of all referrals made or received), being excluded from subsequent doctor profiles analysis. Cluster analysis found 951 (23.9%) doctors to be central in the graph and 1,258 (31.6%) to be peripheral; 883 (22.2%) to be authorities and 266 (6.7%) as seeking authorities; 3,684 (92.6%) mostly shared patients with colleagues, with patient follow-up intensities ranging from weak to strong. Wide profile dispersion was observed among specialties and, more interestingly, within specialties. Non-primary-care medical specialties (e.g., cardiology, endocrinology etc.) were associated with central profile in the graph, while surgical specialties predominated in the periphery, along with pediatrics. Only pediatrics was associated with strong and prevalent (i.e., low patient sharing pattern) follow-up. Many doctors from internal medicine and family medicine had unexpectedly weak and shared patient follow-up profiles. Doctor profiles exhibited pairwise relationships with each other and with the number of chronic comorbidities of the patients they treated. For example, physicians identified as authorities were frequently central and treated patients with more comorbidities. Ten medical communities were identified with clear territorial and specialty segregation.

CONCLUSIONS

Viewing the Amb-HCN as a social network provided a topological and functional representation with potentially meaningful and actionable emerging insights into the most influential actors and specialties, functional hierarchies, factors that lead to self-constituted medical communities, and dispersion from expected patterns within medical specialties.

Increased pediatric RSV case counts following the emergence of SARS-CoV-2 are attributable to increased testing

Background

The incidence of respiratory syncytial virus (RSV) dropped markedly early in the COVID-19 pandemic, followed by a resurgence with heightened case counts. The "immunity debt" hypothesis proposes that the RSV-naive pediatric population increased during the period of low transmission, resulting in a subsequent increased risk of infection. However, the evidence supporting this hypothesis is limited, and no studies have comprehensively evaluated the role of changing respiratory viral testing practices in the perceived surge.

Methods

We conducted a multicenter, retrospective analysis of 342,530 RSV encounters and 980,546 RSV diagnostic tests occurring at 32 United States pediatric hospitals between 2013 and 2023. We used interrupted time series analysis to estimate pandemic-associated changes in RSV patient and testing volume, and to quantify changes in the proportions of patients admitted from the emergency department (ED), admitted to the intensive care unit (ICU), and receiving mechanical ventilation. We quantified the fraction of the observed shifts in case counts and in the age of diagnosed patients attributable to changes in RSV testing practices. Finally, we analyzed 524,404 influenza virus encounters and 1,768,526 influenza diagnostic tests to address the specificity of the findings to RSV.

Findings

RSV patient volume increased 2.4-fold (95% CI: 1.7, 3.5) in 2021-2023 relative to the pre-pandemic phase, and was accompanied by an 18.9-fold increase (95% CI: 15.0, 23.9) in RSV test volume. Over two-thirds of the apparent shifts in patient volume and in patient age were attributable to increased testing, which was concentrated among older pediatric patients. The proportions of patients with RSV requiring hospitalization, intensive care, or mechanical ventilation declined significantly across all patient age groups. These declines were not observed for patients with influenza virus.

Interpretation

A surge in RSV testing, rather than in viral circulation, likely underlies the increased case counts observed in 2021-2023. We identify expected consequences of increased testing, including the diagnosis of less severe cases and a shift in the patient age distribution. These findings warrant a critical assessment of the immunity debt hypothesis, while highlighting the importance of considering the testing denominator when surveillance strategies are dynamic.

This cohort study assesses radiographic evidence of pneumonia and antibiotic use in children with clinically suspected community-acquired pneumonia.

Opportunities for Pharmacogenetic Testing to Guide Dosing of Medications in Youths With Medicaid

Importance

There are an increasing number of medications with a high level of evidence for pharmacogenetic-guided dosing (PGx drugs). Knowledge of the prevalence of dispensings of PGx drugs and their associated genes may allow hospitals and clinical laboratories to determine which pharmacogenetic tests to implement.

Objectives

To investigate the prevalence of outpatient dispensings of PGx drugs among Medicaid-insured youths, determine genes most frequently associated with PGx drug dispenses, and describe characteristics of youths who were dispensed at least 1 PGx drug.

Design, Setting, and Participants

This serial cross-sectional study includes data from 2011 to 2019 among youths aged 0 to 17 years in the Marketscan Medicaid database. Data were analyzed from August to December 2022.

Main Outcomes and Measures

PGx drugs were defined as any medication with level A evidence as determined by the Clinical Pharmacogenetics Implementation Consortium (CPIC). The number of unique youths dispensed each PGx drug in each year was determined. PGx drugs were grouped by their associated genes for which there was CPIC level A evidence to guide dosing, and a dispensing rate (No. of PGx drugs/100 000 youths) was determined for each group for the year 2019. Demographics were compared between youths dispensed at least 1 PGx drug and those not dispensed any PGx drugs.

Results

The number of Medicaid-insured youths queried ranged by year from 2 078 683 youths in 2011 to 4 641 494 youths in 2017, including 4 126 349 youths (median [IQR] age, 9 [5-13] years; 2 129 926 males [51.6%]) in 2019. The proportion of Medicaid-insured youths dispensed PGx drugs increased from 289 709 youths (13.9%; 95% CI, 13.8%-14.0%) in 2011 to 740 072 youths (17.9%; 95% CI, 17.9%-18.0%) in 2019. Genes associated with the most frequently dispensed medications were CYP2C9, CYP2D6, and CYP2C19 (9197.0 drugs [95% CI, 9167.7-9226.3 drugs], 8731.5 drugs [95% CI, 8702.5-8759.5 drugs], and 3426.8 drugs [95% CI, 3408.1-3443.9 drugs] per 100 000 youths, respectively). There was a higher percentage of youths with at least 1 chronic medical condition among youths dispensed at least 1 PGx drug (510 445 youths [69.0%; 95% CI, 68.8%-69.1%]) than among 3 386 277 youths dispensed no PGx drug (1 381 544 youths [40.8%; 95% CI, 40.7%-40.9%) (P < .001) in 2019.

Conclusions and Relevance

In this study, there was an increasing prevalence of dispensings for PGx drugs. This finding suggests that pharmacogenetic testing of specific drug-gene pairs should be considered for frequently prescribed PGx drugs and their implicated genes.

Predicting mortality in pediatric sepsis: A nationwide data analysis using a pediatric sepsis surveillance method

INTRODUCTION

A sepsis surveillance method using electronic health records is increasingly used to describe the epidemiology of adult sepsis. However, its application in pediatric populations has been limited, and real-world epidemiology of pediatric sepsis remains unknown. We aimed to determine whether this surveillance method could identify children with sepsis at high-risk of mortality.

PATIENTS AND METHODS

From a nationwide inpatient database in Japan, we included children who underwent blood culture and received antimicrobials for ≥ 4 days between 2014 and 2021. We stratified these children into those with sepsis or without sepsis by the presence of organ dysfunction. We evaluated the discrimination for in-hospital mortality by the sepsis diagnosis and the number of organ dysfunction.

RESULTS

Among 6553 eligible children, in-hospital mortality was 7.2 % in 875 children with sepsis and 0.2 % in 5678 children without sepsis. Sepsis diagnosis discriminated in-hospital mortality with a sensitivity of 0.84 and a specificity of 0.87. The area under the curve for mortality based on the number of organ dysfunction was 0.88 (95 % confidence interval:0.84 to 0.93). In-hospital mortality incrementally increased with the number of organ dysfunction; zero, 0.2 %; one, 3.4 %; two, 12.7 %; three, 20.9 %; four, 33.3 %; and five, 50.0 %.

CONCLUSIONS

The surveillance method effectively identified children with sepsis with high-risk of mortality and demonstrated strong discrimination of mortality.

Cost of Pediatric Pneumonia Episodes With or Without Chest Radiography

BACKGROUND AND OBJECTIVES

Despite its routine use, it is unclear whether chest radiograph (CXR) is a cost-effective strategy in the workup of community-acquired pneumonia (CAP) in the pediatric emergency department (ED). We sought to assess the costs of CAP episodes with and without CXR among children discharged from the ED.

METHODS

This was a retrospective cohort study within the Healthcare Cost and Utilization Project State ED and Inpatient Databases of children aged 3 months to 18 years with CAP discharged from any EDs in 8 states from 2014 to 2019. We evaluated total 28-day costs after ED discharge, including the index visit and subsequent care. Mixed-effects linear regression models adjusted for patient-level variables and illness severity were performed to evaluate the association between CXR and costs.

RESULTS

We evaluated 225c781 children with CAP, and 86.2% had CXR at the index ED visit. Median costs of the 28-day episodes, index ED visits, and subsequent visits were $314 (interquartile range [IQR] 208-497), $288 (IQR 195-433), and $255 (IQR 133-637), respectively. There was a $33 (95% confidence interval [CI] 22-44) savings over 28-days per patient for those who received a CXR compared with no CXR after adjusting for patient-level variables and illness severity. Costs during subsequent visits ($26 savings, 95% CI 16-36) accounted for the majority of the savings as compared with the index ED visit ($6, 95% CI 3-10).

CONCLUSIONS

Performance of CXR for CAP diagnosis is associated with lower costs when considering the downstream provision of care among patients who require subsequent health care after initial ED discharge.

Mechanical Circulatory Support in Pediatric Myocarditis: Support Strategies and Outcomes in a Nationally Representative Cohort

Background

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.

Methods

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.

Results

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).

Conclusion

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.

Acceptability of Dyad Care Management After Preterm Birth: A Qualitative Study

OBJECTIVES

Care management programs for medically complex infants interact with parents after complicated pregnancies, when gaps in maternal health care are well documented. These care managers may have the relationships and skills to promote postpartum and interconception health and health care access. It is unknown whether expanding these care management models to address maternal needs would be acceptable.

METHODS

We conducted qualitative interviews with women with a history of preterm birth and clinicians. For women with a history of preterm birth, additional inclusion criteria were Medicaid-insured infant in one health system and English proficiency. We purposively oversampled women whose infants received care management. Clinicians worked in two geographically adjacent health systems. Interviews explored priorities after preterm birth and perceived acceptability of mother-infant dyad care management. Interviews were audio recorded, transcribed, and coded following an integrated approach in which we applied a priori codes and captured emergent themes.

RESULTS

We interviewed 33 women (10/2018-7/2021) and 24 clinicians (3/2021-8/2021). Women were predominantly non-Hispanic Black, and 15 had infants receiving care management. Clinicians included physicians, nurses, and social workers from Pediatrics, Obstetrics, and Family Medicine. Subgroups converged thematically, finding care management acceptable. Tailoring programs to address stress and sleep, emphasizing care managers with strong interpersonal skills and shared experiences with care management users, and program flexibility would contribute to acceptability.

CONCLUSIONS FOR PRACTICE

Dyad care management after preterm birth is acceptable to potential program end-users and clinicians. Dyad health promotion may contribute to improved birth outcomes, infant, and parent health.

Bugs Behind the Bulging Eyeball: Microbiology and Antibiotic Management in Orbital Cellulitis With or Without Subperiosteal Abscess

The objective of this study is to describe causative pathogens and current antibiotic management among hospitalized children with orbital cellulitis. This retrospective study, performed at a tertiary care children's health system, included patients up to 18 years old who presented with radiographic evidence of orbital cellulitis from 2012 to 2019. Of the 298 patients included in the study, 103 had surgery and an intraoperative culture obtained. A pathogen was recovered in 86 cultures (83.5%). The most common pathogens were Streptococcus anginosus group (26.2%), Streptococcus pyogenes (11.7%), methicillin-susceptible Staphylococcus aureus (10.7%), and Streptococcus pneumoniae (9.7%). Only 8/194 (4.1%) blood cultures returned positive. Median duration of intravenous antibiotics was 4 days and median total duration was 17 days. The most common empiric regimen prescribed was ceftriaxone and clindamycin (64.1%). Despite low incidence of methicillin-resistant S aureus, empiric antibiotics often consisted of 2 antibiotics to ensure coverage for this bacterium.

Association of Discharge Location Following Pediatric Tracheostomy with Social Determinants of Health: A National Analysis

OBJECTIVE

To evaluate the breakdown of discharge locations among pediatric tracheostomy patients and determine the impact of demographic variables and social determinants of health.

STUDY DESIGN

Retrospective review of the 2016 and 2019 Healthcare Cost and Utilization Project Kids' Inpatient Database (HCUP KID).

SETTING

A total of 4000 United States community hospitals, defined as short-term, non-Federal, general, and specialty hospitals.

METHODS

ICD-10-PCS, ICD-10 CM codes, and HCUP data elements were selected for patients and variables of interest. Bivariate comparisons were performed using Rao-Scott Chi-square tests; significance levels in post hoc pairwise testing were adjusted using Bonferroni adjustment. Multinomial generalized logistic regression models were used to determine the average annual odds ratio (OR) of 3 dispositions at discharge relative to discharge home for self-care.

RESULTS

Patients aged 11-17, patients from large metropolitan areas, and patients of "Other" race have an increased odds of discharge to a short- or long-term care facility (all P < .001). Weekend admissions, nonelective admissions, patients in Northeast hospitals, and patients at urban nonteaching hospitals are also more likely to be discharged to a short- or long-term care facility (all P < .001). Mean and median total costs of admission were $424,387 and $243,479, respectively, with a median total charge of $854,499.

CONCLUSION

Among pediatric tracheostomy patients, demographic factors that affect discharge disposition include age, community type, and race, and significant hospital factors include day and type of admission, geographic region, and hospital type. Hospitalizations are associated with high overall costs and charges to the patient, which are increasing over time.

Interfacility Transfer Outcomes Among Children With Complex Chronic Conditions: Associations Between Patient-Level and Hospital-Level Factors and Transfer Outcomes

OBJECTIVES

Determine patient- and referring hospital-level predictors of transfer outcomes among children with 1 or more complex chronic conditions (CCCs) transferred to a large academic medical center.

METHODS

We conducted a retrospective chart review of 2063 pediatric inpatient admissions from 2017 to 2019 with at least 1 CCC defined by International Classification of Diseases, Tenth Revision codes. Charts were excluded if patients were admitted via any route other than transfer from a referring hospital's emergency department or inpatient ward. Patient-level factors were race/ethnicity, payer, and area median income. Hospital-level factors included the clinician type initiating transfer and whether the referring-hospital had an inpatient pediatric ward. Transfer outcomes were rapid response within 24 hours of admission, Pediatric Early Warning Score at admission, and hours to arrival. Regression analyses adjusted for age were used to determine association between patient- and hospital-level predictors with transfer outcomes.

RESULTS

There were no significant associations between patient-level predictors and transfer outcomes. Hospital-level adjusted analyses indicated that transfers from hospitals without inpatient pediatrics wards had lower odds of ICU admission during hospitalization (odds ratio, 0.46; 95% confidence interval, 0.22-0.97) and shorter transfer times (β-coefficient, -2.54; 95% CI, -3.60 to -1.49) versus transfers from hospitals with inpatient pediatrics wards. There were no significant associations between clinician type and transfer outcomes.

CONCLUSIONS

For pediatric patients with CCCs, patient-level predictors were not associated with clinical outcomes. Transfers from hospitals without inpatient pediatric wards were less likely to require ICU admission and had shorter interfacility transfer times compared with those from hospitals with inpatient pediatrics wards.

Racial Inequities in Palliative Referral for Children with High-Intensity Neurologic Impairment

OBJECTIVE

To evaluate whether racial and socioeconomic inequities in pediatric palliative care utilization extend to children with high-intensity neurologic impairment (HI-NI), which is a chronic neurological diagnosis resulting in substantial functional morbidity and mortality.

STUDY DESIGN

We conducted a retrospective study of patients with HI-NI who received primary care services at a tertiary care center from 2014 through 2019. HI-NI diagnoses that warranted a palliative care referral were identified by consensus of a multidisciplinary team. The outcome was referral to palliative care. The primary exposure was race, categorized as Black or non-Black to represent the impact of anti-Black racism. Additional exposures included ethnicity (Hispanic/non-Hispanic) and insurance status (Medicaid/non-Medicaid). Descriptive statistics, bivariate analyses, and multivariable logistic regression models were performed to assess associations between exposures and palliative care referral.

RESULTS

A total of 801 patients with HI-NI were included; 7.5% received a palliative referral. There were no differences in gestational age, sex, or ethnicity between patients who received a referral and those who did not. In multivariable analysis, adjusting for ethnicity, sex, gestational age, and presence of complex chronic conditions, Black children (aOR 0.47, 95% CI 0.26, 0.84) and children with Medicaid insurance (aOR 0.40, 95% CI 0.23, 0.70) each had significantly lower odds of palliative referral compared with their non-Black and non-Medicaid-insured peers, respectively.

CONCLUSIONS

We identified inequities in pediatric palliative care referral among children with HI-NI by race and insurance status. Future work is needed to develop interventions, with families, aimed at promoting more equitable, antiracist systems of palliative care.

Utility of Hospital Failure to Rescue for Analyzing Variation in Pediatric Postoperative Mortality

OBJECTIVES

To evaluate the association between pediatric hospital performances in terms of failure to rescue (FTR), defined as postoperative mortality after a surgical complication, and mortality among patients without a surgical complication.

DESIGN

Retrospective cohort study.

SETTING

Forty-eight academic, pediatric hospitals; data obtained from Pediatric Health Information System database (Child Health Corporation of America, Shawnee Mission, KS) (2012-2020).

PATIENTS

Children who underwent at least one of 57 high-risk operations associated with significant postoperative mortality.

EXPOSURES

Hospitals were stratified into quintiles of reliability adjusted FTR (lower than average FTR in quintile 1 [Q1], higher than average FTR in quintile 5 [Q5]). Multivariable hierarchical regression was used to evaluate the association between hospital FTR performance and mortality among patients who did not have a surgical complication.

MEASUREMENTS AND MAIN RESULTS

Among 203,242 children treated across 48 academic hospitals, the complication and overall postoperative mortality rates were 8.8% and 2.3%, respectively. Among patients who had a complication, the FTR rate was 8.8%. Among patients who did not have a complication, the mortality rate was 1.7%. There was a 6.5-fold increase in reliability adjusted FTR between the lowest and highest performing hospitals (lowest FTR hospital-2.7%; 95% CI [1.6-3.9]; highest FTR hospital-17.8% [16.8-18.8]). Complex chronic conditions were highly prevalent across hospitals (Q1, 72.7%; Q2, 73.8%; Q3, 72.2%; Q4, 74.0%; Q5, 74.8%; trend test p < 0.01). Relative to Q1 hospitals, the odds of mortality in the absence of a postoperative complication significantly increased by 33% at Q5 hospitals (odds ratio 1.33; 95% CI [1.07-1.66]). This association was consistent when limited to patients with a complex chronic condition and neonates.

CONCLUSION

FTR may be a useful and valid surgical quality measure for pediatric surgery, even when considering patients without a postoperative complication. These findings suggest practices and processes for preventing FTR at high performing pediatric hospitals might help mitigate the risk of postoperative mortality even in the absence of a postoperative complication.

Short stay unit led by pediatric hospital medicine advanced practice providers

BACKGROUND

In response to a critical pediatric bed shortage in 2022, an urgent process change was required to provide safe and timely medical care. We proposed a pilot for an advanced practice provider (APP)-run short stay unit (SSU) for select pediatric hospital medicine (PHM) patients.

OBJECTIVE

To compare length of stay (LOS) and cost before and after implementation of a PHM APP-led SSU pilot at a tertiary pediatric hospital.

DESIGNS, SETTINGS, AND PARTICIPANTS

Single-center prospective pilot observational cohort study with historical control. Observation encounters for patients with asthma, bronchiolitis, croup, and dehydration were included.

INTERVENTION

An independent-practice model SSU staffed by APPs on the PHM service.

MAIN OUTCOME AND MEASURES

SSU encounters (September 1, 2022-December 1, 2022) were compared against pre-SSU encounters (September 1, 2021-August 31, 2022). Cohorts were described with summary statistics. SSU encounters were matched against pre-SSU encounters based on demographics and diagnosis, and the average effect of treatment was calculated. LOS was abstracted from the enterprise data warehouse and standardized unit cost from the Pediatric Health Information Systems database.

RESULTS

There were 1110 encounters included, 155 in the SSU cohort and 955 in the pre-SSU cohort: 24.2% asthma, 30.8% bronchiolitis, 8.3% croup, and 36.7% dehydration. Median (interquartile range) unit LOS decreased from 21 (16-26) to 18 (10-22) h, p < .001. Cost decreased from $3593 ($3031-$4560) to $2958 ($2278-$3856), p < .001. After matching, the average treatment effect was reduction of 3.88 h (95% confidence interval [CI] 1.91-5.85) and $593 (95% CI $348-$839). There were no significant differences in 7-day ED revisit rates.

Respiratory culture growth and 3-years lung health outcomes in children with bronchopulmonary dysplasia and tracheostomies

BACKGROUND

While bacteria identification on respiratory cultures is associated with poor short-term outcomes in children with bronchopulmonary dysplasia (BPD) and tracheostomies, the influence on longer-term respiratory support needs remains unknown.

OBJECTIVE

To determine if respiratory culture growth of pathogenic organisms is associated with ongoing need for respiratory support, decannulation, and death at 3 years posttracheostomy placement in children with BPD and tracheostomies.

METHODS

This single center, retrospective cohort study included infants and children with BPD and tracheostomies placed 2010-2018 and ≥1 respiratory culture obtained in 36 months posttracheostomy. Primary predictor was any pathogen identified on respiratory culture. Additional predictors were any Pseudomonas aeruginosa and chronic P. aeruginosa identification. Outcomes included continued use of respiratory support (e.g., oxygen, positive pressure), decannulation, and death at 3 years posttracheostomy. We used Poisson regression models to examine the relationship between respiratory organisms and outcomes, controlling for patient-level covariates and within-patient clustering.

RESULTS

Among 170 children, 59.4% had a pathogen identified, 28.8% ever had P. aeruginosa, and 3.5% had chronic P. aeruginosa. At 3 years, 33.1% of alive children required ongoing respiratory support and 24.8% achieved decannulation; 18.9% were deceased. In adjusted analysis, any pathogen and P. aeruginosa were not associated with ongoing respiratory support or mortality. However, P. aeruginosa was associated with decreased decannulation probability (adjusted risk ratio 0.48, 95% CI 0.23-0.98). Chronic P. aeruginosa was associated with lower survival probability.

CONCLUSION

Our findings suggest that respiratory pathogens including P. aeruginosa may not promote long-term respiratory dysfunction, but identification of P. aeruginosa may delay decannulation.

Adverse Safety Events in Emergency Medical Services Care of Children With Out-of-Hospital Cardiac Arrest

Importance

Survival for children with out-of-hospital cardiac arrest (OHCA) remains poor despite improvements in adult OHCA survival.

Objective

To characterize the frequency of and factors associated with adverse safety events (ASEs) in pediatric OHCA.

Design, Setting, and Participants

This population-based retrospective cohort study examined patient care reports from 51 emergency medical services (EMS) agencies in California, Georgia, Oregon, Pennsylvania, Texas, and Wisconsin for children younger than 18 years with an OHCA in which resuscitation was attempted by EMS personnel between 2013 and 2019. Medical record review was conducted from January 2019 to April 2022 and data analysis from October 2022 to February 2023.

Main Outcomes and Measure

Severe ASEs during the patient encounter (eg, failure to give an indicated medication, 10-fold medication overdose).

Results

A total of 1019 encounters of EMS-treated pediatric OHCA were evaluated; 465 patients (46%) were younger than 12 months. At least 1 severe ASE occurred in 610 patients (60%), and 310 patients (30%) had 2 or more. Neonates had the highest frequency of ASEs. The most common severe ASEs involved epinephrine administration (332 [30%]), vascular access (212 [19%]), and ventilation (160 [14%]). In multivariable logistic regression, the only factor associated with severe ASEs was young age. Neonates with birth-related and non-birth-related OHCA had greater odds of a severe ASE compared with adolescents (birth-related: odds ratio [OR], 7.0; 95% CI, 3.1-16.1; non-birth-related: OR, 3.4; 95% CI, 1.2-9.6).

Conclusions and Relevance

In this large geographically diverse cohort of children with EMS-treated OHCA, 60% of all patients experienced at least 1 severe ASE. The odds of a severe ASE were higher for neonates than adolescents and even higher when the cardiac arrest was birth related. Given the national increase in out-of-hospital births and ongoing poor outcomes of OHCA in young children, these findings represent an urgent call to action to improve care delivery and training for this population.

Analysis of a Medication Safety Intervention in the Pediatric Emergency Department

Importance

Strategies to reduce medication dosing errors are crucial for improving outcomes. The Medication Education for Dosing Safety (MEDS) intervention, consisting of a simplified handout, dosing syringe, dose demonstration and teach-back, was shown to be effective in the emergency department (ED), but optimal intervention strategies to move it into clinical practice remain to be described.

Objective

To describe implementation of MEDS in routine clinical practice and associated outcomes.

Design, Setting, and Participants

This mixed-methods interrupted time series study of MEDS was conducted April 2021 to December 2022 in an academic pediatric ED using a hybrid type 1 design. Parents and guardians of children aged 90 days to 11.9 years who were discharged with acetaminophen, ibuprofen, or both were eligible for inclusion in the quantitative portion. Clinicians from a diversity of role groups (attending physician, resident, and nurse) were eligible for the qualitative portion.

Exposures

The study was conducted in 5 stages (baseline, intervention 1, washout, intervention 2, and sustainability phases). The 2 intervention phases taught clinical staff the MEDS intervention using different implementation strategies. During the intervention 1 phase, in-depth interviews were conducted until thematic saturation was reached; results were analyzed using thematic analysis. Interviews informed intervention 2 phase interventions.

Main Outcomes and Measures

The primary outcome was any error (defined as dosing or frequency error) at a 48- to 72-hour follow-up phone call.

Results

There were 256 participants (median [IQR] child age, 1.7 [3.0-7.0] years; median [IQR] parent and guardian age, 36.0 [31.0-41.0] years; 200 females among parents and guardians [78.1%]) who consented and completed follow-up. At baseline, 44 of 68 participants (64.7%) made an error compared with 34 of 65 participants (52.3%) during intervention 1, 31 of 63 participants (49.X%) during intervention 2, and 34 of 60 participants (57.X%) during sustainability. After adjustment for language and health literacy, the adjusted odds ratio for error during the combined intervention phases was 0.52 (95% CI, 0.28-0.97) compared with baseline.

Conclusions and Relevance

This study found that both MEDS intervention phases were associated with decreased risk of error and that some improvement was sustained without active intervention. These findings suggest that attempts to develop simplified, brief interventions may be associated with improved medication safety for children after discharge from the ED.

Health Literacy-Informed Communication to Reduce Discharge Medication Errors in Hospitalized Children: A Randomized Clinical Trial

Importance

Inadequate communication between caregivers and clinicians at hospital discharge contributes to medication dosing errors in children. Health literacy-informed communication strategies during medication counseling can reduce dosing errors but have not been tested in the pediatric hospital setting.

Objective

To test a health literacy-informed communication intervention to decrease liquid medication dosing errors compared with standard counseling in hospitalized children.

Design, Setting, and Participants

This parallel, randomized clinical trial was performed from June 22, 2021, to August 20, 2022, at a tertiary care, US children's hospital. English- and Spanish-speaking caregivers of hospitalized children 6 years or younger prescribed a new, scheduled liquid medication at discharge were included in the analysis.

Interventions

Permuted block (n = 4) randomization (1:1) to a health literacy-informed discharge medication communication bundle (n = 99) compared with standard counseling (n = 99). A study team member delivered the intervention consisting of a written, pictogram-based medication instruction sheet, teach back (caregivers state information taught), and demonstration of dosing with show back (caregivers show how they would draw the liquid medication in the syringe).

Main Outcome and Measures

Observed dosing errors, assessed using a caregiver-submitted photograph of their child's medication-filled syringe and expressed as the percentage difference from the prescribed dose. Secondary outcomes included caregiver-reported medication knowledge. Outcome measurements were blinded to participant group assignment.

Results

Among 198 caregivers randomized (mean [SD] age, 31.4 [6.5] years; 186 women [93.9%]; 36 [18.2%] Hispanic or Latino and 158 [79.8%] White), the primary outcome was available for 151 (76.3%). The observed mean (SD) percentage dosing error was 1.0% (2.2 percentage points) among the intervention group and 3.3% (5.1 percentage points) among the standard counseling group (absolute difference, 2.3 [95% CI, 1.0-3.6] percentage points; P < .001). Twenty-four of 79 caregivers in the intervention group (30.4%) measured an incorrect dose compared with 39 of 72 (54.2%) in the standard counseling group (P = .003). The intervention enhanced caregiver-reported medication knowledge compared with the standard counseling group for medication dose (71 of 76 [93.4%] vs 55 of 69 [79.7%]; P = .03), duration of administration (65 of 76 [85.5%] vs 49 of 69 [71.0%]; P = .04), and correct reporting of 2 or more medication adverse effects (60 of 76 [78.9%] vs 13 of 69 [18.8%]; P < .001). There were no differences in knowledge of medication name, indication, frequency, or storage.

Conclusions and Relevance

A health literacy-informed discharge medication communication bundle reduced home liquid medication administration errors and enhanced caregiver medication knowledge compared with standard counseling. Routine use of these standardized strategies can promote patient safety following hospital discharge.

Race, Ethnicity, Language, and the Treatment of Low-Risk Febrile Infants

Importance

Febrile infants at low risk of invasive bacterial infections are unlikely to benefit from lumbar puncture, antibiotics, or hospitalization, yet these are commonly performed. It is not known if there are differences in management by race, ethnicity, or language.

Objective

To investigate associations between race, ethnicity, and language and additional interventions (lumbar puncture, empirical antibiotics, and hospitalization) in well-appearing febrile infants at low risk of invasive bacterial infection.

Design, Setting, and Participants

This was a multicenter retrospective cross-sectional analysis of infants receiving emergency department care between January 1, 2018, and December 31, 2019. Data were analyzed from December 2022 to July 2023. Pediatric emergency departments were determined through the Pediatric Emergency Medicine Collaborative Research Committee. Well-appearing febrile infants aged 29 to 60 days at low risk of invasive bacterial infection based on blood and urine testing were included. Data were available for 9847 infants, and 4042 were included following exclusions for ill appearance, medical history, and diagnosis of a focal infectious source.

Exposures

Infant race and ethnicity (non-Hispanic Black, Hispanic, non-Hispanic White, and other race or ethnicity) and language used for medical care (English and language other than English).

Main Outcomes and Measures

The primary outcome was receipt of at least 1 of lumbar puncture, empirical antibiotics, or hospitalization. We performed bivariate and multivariable logistic regression with sum contrasts for comparisons. Individual components were assessed as secondary outcomes.

Results

Across 34 sites, 4042 infants (median [IQR] age, 45 [38-53] days; 1561 [44.4% of the 3516 without missing sex] female; 612 [15.1%] non-Hispanic Black, 1054 [26.1%] Hispanic, 1741 [43.1%] non-Hispanic White, and 352 [9.1%] other race or ethnicity; 3555 [88.0%] English and 463 [12.0%] language other than English) met inclusion criteria. The primary outcome occurred in 969 infants (24%). Race and ethnicity were not associated with the primary composite outcome. Compared to the grand mean, infants of families that use a language other than English had higher odds of the primary outcome (adjusted odds ratio [aOR]; 1.16; 95% CI, 1.01-1.33). In secondary analyses, Hispanic infants, compared to the grand mean, had lower odds of hospital admission (aOR, 0.76; 95% CI, 0.63-0.93). Compared to the grand mean, infants of families that use a language other than English had higher odds of hospital admission (aOR, 1.08; 95% CI, 1.08-1.46).

Conclusions and Relevance

Among low-risk febrile infants, language used for medical care was associated with the use of at least 1 nonindicated intervention, but race and ethnicity were not. Secondary analyses highlight the complex intersectionality of race, ethnicity, language, and health inequity. As inequitable care may be influenced by communication barriers, new guidelines that emphasize patient-centered communication may create disparities if not implemented with specific attention to equity.

Clinical Practice Patterns, Health Resource Use and Risk Factors for Severe Conditions Among Children Hospitalized With COVID-19 in Japan

BACKGROUND

The trends in clinical practice patterns and health resource use, as well as risk factors for severe conditions among children hospitalized with coronavirus disease-2019 (COVID-19), remain unclear.

MATERIALS AND METHODS

We conducted a retrospective observational study consisting of 9876 children hospitalized with COVID-19 during 2020-2022 using the Medical Data Vision database in Japan. We investigated trends in patient characteristics, health resource use, treatment patterns and laboratory data. Additionally, log-binomial regression models were used to investigate the risk factors associated with severe COVID-19 among pediatric inpatients with COVID-19.

RESULTS

We observed decreasing trends in the lengths of hospital stays, healthcare costs, computed tomography use, and antibiotic use, and increasing trends in treatment with intravenous hydration and use of antipyretics, antiepileptics, antiemetics and antivirals from the first wave to the seventh wave of COVID-19 pandemic. During the 3-year period, the risk of severe COVID-19 was almost stable at 3%. Risk factors associated with severe COVID-19 were children less than 1 year old [risk ratio (RR): 1.69; 95% confidence interval (CI): 1.02-2.78], the number of complex chronic diseases (RR for 1 disease: 4.49; 95% CI: 2.76-7.32; RR for 2 or more diseases: 10.2; 95% CI: 5.19-20.3) and asthma (RR: 1.84; 95% CI: 1.06-3.20).

CONCLUSIONS

Our study observed the changes in practice patterns and health resource use for children hospitalized with COVID-19 and identified risk factors associated with severe COVID-19. These findings indicate the importance of vigilant monitoring and tailored treatment strategies in children with these risk factors.

An examination of characteristics, social supports, caregiver resilience and hospital readmissions of children with medical complexity

BACKGROUND

Children with medical complexity (CMC) account for 1% of children in the United States. These children experience frequent hospital readmissions, high healthcare costs and poor health outcomes. A link between CMC caregiver social support, resilience and hospital readmissions has never been fully investigated. This study examines the feasibility of a prospective, descriptive, repeated measures research design to characterize CMC and their caregivers, social supports, caregiver resilience and hospital readmissions to inform a larger prospective investigation.

METHODS

Caregivers of CMC with unplanned hospitalizations completed surveys at the index hospitalization and 30 and 60 days after discharge. CMC caregiver and child characteristics, social supports and hospital readmissions were examined using an investigator-developed survey. Resilience was measured using the Resilience Scale-14© (7-Point Likert Scale, score range 14-98), and feasibility was measured by calculating enrolment, attrition, survey completion and item response. Analysis included descriptive statistics and qualitative data visualization.

RESULTS

Of caregivers who were approached for participation, 81.1% consented  and completed 76 surveys. Attrition was 31%. Item response rates were ≥ 90% for all but one item. A total of 62.1% of children had hospital readmissions within 90 days and 37.9% within 30 days. Additionally, 70% of caregivers had home care nursing, but the approved hours were only partially filled. More than 70% of caregiver resilience scores were moderate to high (score range 74-98) and were stable across repeated measures and hospital readmissions. Open-ended question responses revealed the following five categories: All-consuming, Family Reliance, Impact of Covid, Taking Action and Broken System.

CONCLUSIONS

Studying CMC caregiver social supports and resilience using repeated measures is feasible. CMC caregivers reported stressors including coordinating their child's substantial healthcare needs and managing partially filled home care nursing hours. Caregiver resilience remained stable over time, amidst frequent CMC hospital readmissions. Findings can inform future research priorities and power analyses for CMC caregiver resilience.

Trends in Low-Value Care Among Children's Hospitals

BACKGROUND AND OBJECTIVES

Longitudinal pediatric low-value care (LVC) trends are not well established. We used the Pediatric Health Information System LVC Calculator, which measures utilization of 30 nonevidenced-based services, to report 7-year LVC trends.

METHODS

This retrospective cohort study applied the LVC Calculator to emergency department (ED) and hospital encounters from January 1, 2016, to December 31, 2022. We used generalized estimating equation models accounting for hospital clustering to assess temporal changes in LVC.

RESULTS

There were 5 265 153 eligible ED encounters and 1 301 613 eligible hospitalizations. In 2022, of 21 LVC measures applicable to the ED cohort, the percentage of encounters with LVC had increased for 11 measures, decreased for 1, and remained unchanged for 9 as compared with 2016. Computed tomography for minor head injury had the largest increase (17%-23%; P < .001); bronchodilators for bronchiolitis decreased (22%-17%; P = .001). Of 26 hospitalization measures, LVC increased for 6 measures, decreased for 9, and was unchanged for 11. Inflammatory marker testing for pneumonia had the largest increase (23%-38%; P = .003); broad-spectrum antibiotic use for pneumonia had the largest decrease (60%-48%; P < .001). LVC remained unchanged or decreased for most medication and procedure measures, but remained unchanged or increased for most laboratory and imaging measures.

CONCLUSIONS

LVC improved for a minority of services between 2016 and 2022. Trends were more favorable for therapeutic (medications and procedures) than diagnostic measures (imaging and laboratory studies). These data may inform prioritization of deimplementation efforts.

A Longitudinal Study of Health Care Utilization Among Infants Investigated for Maltreatment

OBJECTIVE

To evaluate whether maltreatment investigated during infancy affects high-acuity health care utilization patterns during early childhood.

METHODS

Retrospective case-control study based on linked data between child protection and hospital encounter records conducted to review health records of infants investigated for abuse and/or neglect. Cases and controls were followed longitudinally through the Rady Children's Hospital electronic health records for 4 years starting at the age of 1 year.

RESULTS

A total of 3692 children were investigated for maltreatment within the first year of life. When comparisons were made between children reported for maltreatment and matched controls, children with infancy maltreatment reports had significantly more high-acuity health care encounters than matched controls (average treatment effect = 1.53, 95% Confidence Interval 1.08-1.99, P < .001).

CONCLUSIONS

Infants investigated for maltreatment have greater high-acuity health care utilization in early childhood. These findings highlight this population's need for well-defined medical homes to ensure appropriate health care. Further understanding of the underlying reasons for this increased health care burden will help inform these efforts.

Child Opportunity Index Disparities in Pediatric Surgical Encounters During the Coronavirus 2019 Pandemic

OBJECTIVE

Surgical encounters decreased during the coronavirus disease (COVID-19) pandemic and may have been deferred more in children with impeded health care access related to social/community risk factors. We compared surgery trends before and during the pandemic by Child Opportunity Index (COI).

METHODS

Retrospective analysis of 321,998 elective surgical encounters of children ages 0-to-18 years in 44 US children's hospitals from January 1, 2017 to December 31, 2021. We used auto-regression to compare observed versus predicted encounters by month in 2020-21, modeled from 2017 to 2019 trends. Encounters were compared by COI score (very low, low, moderate, high, very high) based on education, health/environment, and social/economic attributes of the zip code from the children's home residence.

RESULTS

Most surgeries were on the musculoskeletal (28.1%), ear/nose/pharynx (17.1%), cardiovascular (15.1%), and digestive (9.1%) systems; 20.6% of encounters were for children with very low COI, 20.8% low COI, 19.8% moderate COI, 18.6% high COI, and 20.1% very high COI. Reductions in observed volume of 2020-21 surgeries compared with predicted varied significantly by COI, ranging from -11.3% (95% confidence interval [CI] -14.1%, -8.7%) for very low COI to -2.6% (95%CI -3.9%, 0.7%) for high COI. Variation by COI emerged in June 2020, as the volume of elective surgery encounters neared baseline. For 12 of the next 18 months, the reduction in volume of elective surgery encounters was the greatest in children with very low COI.

CONCLUSIONS

Children from very low COI zip codes experienced the greatest reduction in elective surgery encounters during early COVID-19 without a subsequent increase in encounters over time to counterbalance the reduction.

Feasibility of social network analysis to study outcomes of children with medical complexity

Since most care for children with medical complexity (CMC) is delivered daily in communities by multiple caregiving individuals, that is, caregiving networks, tools to assess and intervene across these networks are needed. This study evaluated the feasibility of applying social network analysis (SNA) to describe caregiving networks. Because hospitalization is among the most frequently used outcomes for CMC, exploratory correlations between network characteristics and CMC hospital use were evaluated. Within 3 weeks, the goal network enrollment was achieved, and all feasibility measures were favorable. Network characteristics correlated with hospital use, that is, smaller, denser networks, with more closed-loop communication correlated with fewer hospital days. Networks with more professional caregivers also correlated with fewer hospital days. SNA is a feasible tool to study CMC caregiving networks. Preliminary data support rigorous hypothesis testing using SNA methods. Network-based interventions to improve CMC health may be an important future direction.

Time to Positive Blood and Cerebrospinal Fluid Cultures in Hypothermic Young Infants

BACKGROUND AND OBJECTIVE

Hypothermia in young infants may be secondary to an invasive bacterial infection. No studies have explored culture time-to-positivity (TTP) in hypothermic infants. Our objective was to compare TTP of blood and cerebrospinal fluid (CSF) cultures between pathogenic and contaminant bacteria in hypothermic infants ≤90 days of age.

METHODS

Secondary analysis of a retrospective cohort of 9 children's hospitals. Infants ≤90 days of age presenting to the emergency department or inpatient setting with hypothermia from September 1, 2017, to May 5, 2021, with positive blood or CSF cultures were included. Differences in continuous variables between pathogenic and contaminant organism groups were tested using a 2-sample t test and 95% confidence intervals for the mean differences reported.

RESULTS

Seventy-seven infants met inclusion criteria. Seventy-one blood cultures were positive, with 20 (28.2%) treated as pathogenic organisms. Five (50%) of 10 positive CSF cultures were treated as pathogenic. The median (interquartile range [IQR]) TTP for pathogenic blood cultures was 16.8 (IQR 12.7-19.2) hours compared with 26.11 (IQR 20.5-48.1) hours for contaminant organisms (P < .001). The median TTP for pathogenic organisms on CSF cultures was 34.3 (IQR 2.0-53.7) hours, compared with 58.1 (IQR 52-72) hours for contaminant CSF organisms (P < .186).

CONCLUSIONS

Our study is the first to compare the TTP of blood and CSF cultures between pathogenic and contaminant bacteria in hypothermic infants. All pathogenic bacteria in the blood grew within 36 hours. No difference in TTP of CSF cultures between pathogenic and contaminant bacteria was detected.

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

BACKGROUND AND OBJECTIVES

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.

METHODS

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.

RESULTS

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.

CONCLUSIONS

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.

Withholding life support for children with severe neurological impairment: Prevalence and predictive factors prior to admission in the PICU

BACKGROUND

Our study aimed to evaluate the prevalence and predictive factors of withholding life support for children suffering from severe neurological impairment before admission to the pediatric intensive care unit (PICU).

METHOD

Children under 18 years of age with severe neurological impairment, who were hospitalized between January 2006 and December 2016, were included in this retrospective study. They were allocated to a withholding group or a control group, depending on whether life support was withheld or not, before admission to the PICU.

RESULTS

Overall, 119 patients were included. At admission to the PICU, the rate of withholding life support was 10 % (n = 12). Predictive factors were: (1) a previous stay in the PICU (n = 11; 92 %, p<0.01, odds ratio [OR]: 14 [2-635], p = 0.001); (2) the need for respiratory support (n = 5; 42 %, p = 0.01, OR: 6 [1-27], p = 0.01); (3) the need for feeding support (n = 10; 83 %, p = 0.01, OR: 10 [2-100], p = 0.001); and (4) a higher functional status score (FSS: 16 [12.5-19] vs. 10 [8-13], p<0.01).

CONCLUSION

The withholding of life support for children suffering from severe neurological impairment appeared limited in our pediatric department. The main predictor was at least one admission to the PICU, which raised the question of the pediatrician's role in the decision to withhold life support.

Racial, ethnic and language disparities in healthcare utilization in pediatric patients following tonsillectomy

IMPORTANCE

Tonsillectomy is one of the most common surgical procedures performed in the United States. However, there is little known about the intersectionality of race, ethnicity, and language and how these factors influence post-tonsillectomy outcomes such as ED utilization and hospital readmission rates.

OBJECTIVE

To examine disparities in emergency department (ED) utilization and hospital readmissions for post-tonsillectomy complications based on insurance status, patient race, ethnicity and language spoken.

DESIGN

This was retrospective cohort over four years.

SETTING

Tertiary Care Children's Hospital.

PARTICIPANTS

All children (n = 10,215) who underwent tonsillectomy or adenotonsillectomy at a tertiary children's hospital from January 2015 to December 2018 were identified and included. There were no exclusion criteria.

EXPOSURE

The exposure of interest was tonsillectomy.

MAIN OUTCOMES AND MEASURES

Outcomes and variables of interest were defined prior to data collection. The primary outcome of this study was emergency department (ED) utilization defined as any ED or urgent care visit within 21 days of the tonsillectomy for surgery-related concerns. The secondary outcome of this study was readmissions following tonsillectomy.

RESULTS

A total of 10215 pediatric patients (median age, 6 years; 5096 [50 %] male) who underwent tonsillectomy were included in the analysis. 13 % of patients presented to the ED with surgery-related complaints. Among English proficient patients, multi-racial patients were the only group with an elevated odds of ED utilization (OR:1.5, 95 % CI: 1.2, 1.9). Non-English language preference (NELP) patients of Black, Hispanic, Asian, and American Indian/Alaskan Native race/ethnicity also had elevated odds of ED use post-tonsillectomy compared to non-Hispanic White English proficient patients. Six percent of all patients had an unplanned hospital readmission. Asian patients with non-English language preference had 2.1 times the odds of readmission (95 % CI: 1.2, 3.6); and were disproportionately admitted for post-tonsillectomy hemorrhage.

CONCLUSIONS

and Relevance: Language disparities in ED use and readmission persist after adjusting for risk factors. Non-English language preference populations have a higher rate of ED utilization, especially for minor complications. Disparities may result from differential health literacy or predispositions to complications. Future directions include additional research on mechanisms and targeted interventions to increase education and access to language-appropriate resources.

Concerns of Primary Caregivers of Children with Complex Chronic Conditions in Kerala: A Qualitative Analysis

Objectives

Exploring data on primary caregiver experiences of dealing with chronically ill children (CIC) strengthens the ability of paediatricians to improve the quality of care by detecting unmet needs in paediatric palliative care and understanding their original concerns instead of presumed needs. Hence, this study aims to identify and describe the primary concerns and challenges faced by caregivers of children with complex chronic conditions in a tertiary care hospital in Kerala.

Materials and Methods

Primary caregivers of 25 children aged <13 years with non-malignant life-limiting illnesses, admitted to the paediatric department of a government medical college in Kerala between 1 July 2021 and 28 February 2022, underwent in-depth interviews to analyse their most worrisome issues. Thematic analysis was the method chosen for qualitative data analysis.

Results

The main themes identified were medical issues, unmet needs, caregiver health issues, and social and financial issues. Among the medical issues, poor seizure control and infected bedsores, sleep deprivation in both patient as well as caregivers, and difficulty in maintaining the personal hygiene of patients were the major issues. Parents of almost all the CICs reported that they required diapers more than any other material or device. Maternal depression was the major caregiver health issue. The unavailability of antiepileptic drugs in peripheral health centres resulted in missing doses and undue expenses for travel to tertiary centres to obtain the same. Caregivers reported their dismay when they finally realised that they were given false hopes of a cure by different systems of medicine.

Conclusion

The challenges faced by caregivers of children with complex chronic conditions are multifaceted. Their most problematic issues related to medical issues are the occurrence of breakthrough seizures and development of infected bedsores. The most important material hardship reported was diaper needs. Caregiver issues such as sleep deprivation and maternal depression must be identified and addressed while providing comprehensive palliative care.

Impact of a Bronchiolitis Clinical Pathway on Management Decisions by Preferred Language

Background

Clinical pathways standardize healthcare utilization, but their impact on healthcare equity is poorly understood. This study aims to measure the effect of a bronchiolitis pathway on management decisions by preferred language for care.

Methods

We included all emergency department encounters for patients aged 1-12 months with bronchiolitis from 1/1/2010 to 10/31/2020. The prepathway period ended 10/31/2011, and the postpathway period was 1/1/2012-10/31/2020. We performed retrospective interrupted time series analyses to assess the impact of the clinical pathway by English versus non-English preferred language on the following outcomes: chest radiography (CXR), albuterol use, 7-day return visit, 72-hour return to admission, antibiotic use, and corticosteroid use. Analyses were adjusted for presence of a complex chronic condition.

Results

There were 1485 encounters in the preperiod (77% English, 14% non-English, 8% missing) and 7840 encounters in the postperiod (79% English, 15% non-English, 6% missing). CXR, antibiotic, and albuterol utilization exhibited sustained decreases over the study period. Pathway impact did not differ by preferred language for any outcome except albuterol utilization. The prepost slope effect of albuterol utilization was 10% greater in the non-English versus the English group (p for the difference by language = 0.022).

Conclusions

A clinical pathway was associated with improvements in care regardless of preferred language. More extensive studies involving multiple pathways and care settings are needed to assess the impact of clinical pathways on health equity.

Asthmalitis? Diagnostic Variability of Asthma and Bronchiolitis in Children <24 Months

BACKGROUND AND OBJECTIVES

Bronchiolitis and asthma have similar acute clinical presentations in young children yet have opposing treatment recommendations. We aimed to assess the role of age and other factors in the diagnosis of bronchiolitis and asthma in children <24 months of age.

METHODS

We conducted a retrospective cross-sectional analysis of the Pediatric Health Information System database. We included children aged <2 years diagnosed with bronchiolitis, asthma, wheeze, or bronchospasm in emergency department or hospital encounters from 2017 to 2021. We described variation by age and between institutions. We used mixed-effects models to assess factors associated with a non-bronchiolitis diagnosis in children 12 to 23 months of age.

RESULTS

We included 554 158 encounters from 42 hospitals. Bronchiolitis made up 98% of encounters for children <3 months of age, whereas asthma diagnoses increased with age and were included in 44% of encounters at 23 months of age. Diagnosis patterns varied widely between hospitals. In children 12 to 23 months of age, the odds of a non-bronchiolitis diagnosis increased with month of age (odds ratio [OR] 1.13, 95% confidence interval [CI] 1.12-1.13), male sex (OR 1.37, 95% CI 1.35-1.40), non-Hispanic Black race (OR 1.54, 95% CI 1.50-1.58), number of previous encounters (OR 2.73, 95% CI 2.61-2.86, for 3 or more encounters), and previous albuterol use (OR 2.24, 95% CI 2.16-2.32).

CONCLUSIONS

Non-bronchiolitis diagnoses and the use of inhaled bronchodilators and systemic steroids for acute wheezing respiratory illness increase with month of age in children aged 0 to 23 months. Better definitions of clinical phenotypes of bronchiolitis and asthma would allow for more appropriate treatment in acute care settings, particularly in children 12 to 23 months of age.

Disparities in Pharmacologic Restraint for Children Hospitalized in Mental Health Crisis

BACKGROUND AND OBJECTIVES

Children hospitalized with a mental health crisis often receive pharmacologic restraint for management of acute agitation. We examined associations between pharmacologic restraint use and race and ethnicity among children admitted for mental health conditions to acute care nonpsychiatric children's hospitals.

METHODS

We performed a retrospective cohort study of children (aged 5-≤18 years) admitted for a primary mental health condition from 2018 to 2022 at 41 US children's hospitals. Pharmacologic restraint use was defined as parenteral administration of medications for acute agitation. The association of race and ethnicity and pharmacologic restraint was assessed using generalized linear multivariable mixed models adjusted for clinical and demographic factors. Stratified analyses were performed based on significant interaction analyses between covariates and race and ethnicity.

RESULTS

The cohort included 61 503 hospitalizations. Compared with non-Hispanic Black children, children of non-Hispanic White (adjusted odds ratio [aOR], 0.81; 95% confidence interval [CI], 0.72-0.92), Asian (aOR, 0.82; 95% CI, 0.68-0.99), or other race and ethnicity (aOR, 0.68; 95% CI, 0.57-0.82) were less likely to receive pharmacologic restraint. There was no significant difference with Hispanic children. When stratified by sex, racial/ethnic differences were magnified in males (aORs, 0.49-0.68), except for Hispanic males, and not found in females (aORs, 0.83-0.93). Sensitivity analysis revealed amplified disparities for all racial/ethnic groups, including Hispanic youth (aOR, 0.65; 95% CI, 0.47-0.91).

CONCLUSIONS

Non-Hispanic Black children were significantly more likely to receive pharmacologic restraint. More research is needed to understand reasons for these disparities, which may be secondary to implicit bias and systemic and interpersonal racism.

Association between mortality and critical events within 48 hours of transfer to the pediatric intensive care unit

Introduction

Critical deterioration in hospitalized children, defined as ward to pediatric intensive care unit (PICU) transfer followed by mechanical ventilation (MV) or vasoactive infusion (VI) within 12 h, has been used as a primary metric to evaluate the effectiveness of clinical interventions or quality improvement initiatives. We explore the association between critical events (CEs), i.e., MV or VI events, within the first 48 h of PICU transfer from the ward or emergency department (ED) and in-hospital mortality.

Methods

We conducted a retrospective study of a cohort of PICU transfers from the ward or the ED at two tertiary-care academic hospitals. We determined the association between mortality and occurrence of CEs within 48 h of PICU transfer after adjusting for age, gender, hospital, and prior comorbidities.

Results

Experiencing a CE within 48 h of PICU transfer was associated with an increased risk of mortality [OR 12.40 (95% CI: 8.12-19.23, P < 0.05)]. The increased risk of mortality was highest in the first 12 h [OR 11.32 (95% CI: 7.51-17.15, P < 0.05)] but persisted in the 12-48 h time interval [OR 2.84 (95% CI: 1.40-5.22, P < 0.05)]. Varying levels of risk were observed when considering ED or ward transfers only, when considering different age groups, and when considering individual 12-h time intervals.

Discussion

We demonstrate that occurrence of a CE within 48 h of PICU transfer was associated with mortality after adjusting for confounders. Studies focusing on the impact of quality improvement efforts may benefit from using CEs within 48 h of PICU transfer as an additional evaluation metric, provided these events could have been influenced by the initiative.

Association of maternal risk factors with infant maltreatment: an administrative data cohort study

OBJECTIVE

We aimed to evaluate the risk of infant maltreatment associated with commonly used criteria for home visiting programmes: young maternal age, maternal adversity (homelessness, substance abuse, intimate partner violence), newcomer status and mental health concerns in Ontario, Canada.

DESIGN

This retrospective cohort study included infants born in hospital in Ontario from 1 April 2005 to 31 March 2017 captured in linked health administrative and demographic databases. Infants were followed from newborn hospitalisation until 1 year of age for child maltreatment captured in healthcare or death records. The association between type and number of maternal risk factors, and maltreatment, was analysed using multivariable logistic regression modelling, controlling for infant characteristics and material deprivation. Further modelling explored the association of each year of maternal age with maltreatment.

RESULTS

Of 989 586 infants, 434 (0.04%) had recorded maltreatment. Maternal age <22 years conferred higher risk of infant maltreatment (adjusted OR (aOR) 5.5, 95% CI 4.5 to 6.8) compared with age ≥22 years. Maternal mental health diagnoses (aOR 2.0, 95% CI 1.6 to 2.5) were also associated with maltreatment, while refugee status appeared protective (aOR 0.6, 95% CI 0.4 to 1.0). The odds of maltreatment increased with higher numbers of maternal risk factors. Maternal age was associated with maltreatment until age 28 years.

CONCLUSION

Infants born to young mothers are at greater risk of infant maltreatment, and this association remained until age 28 years. These findings are important for ensuring public health interventions are supporting populations experiencing structural vulnerabilities with the aim of preventing maltreatment.

Adjusting for Congenital Heart Surgery Risk Using Administrative Data

BACKGROUND

Congenital heart surgery (CHS) encompasses a heterogeneous population of patients and surgeries. Risk standardization models that adjust for patient and procedural characteristics can allow for collective study of these disparate patients and procedures.

OBJECTIVES

We sought to develop a risk-adjustment model for CHS using the newly developed Risk Stratification for Congenital Heart Surgery for ICD-10 Administrative Data (RACHS-2) methodology.

METHODS

Within the Kids' Inpatient Database 2019, we identified all CHSs that could be assigned a RACHS-2 score. Hierarchical logistic regression (clustered on hospital) was used to identify patient and procedural characteristics associated with in-hospital mortality. Model validation was performed using data from 24 State Inpatient Databases during 2017.

RESULTS

Of 5,902,538 total weighted hospital discharges in the Kids' Inpatient Database 2019, 22,310 pediatric cardiac surgeries were identified and assigned a RACHS-2 score. In-hospital mortality occurred in 543 (2.4%) of cases. Using only RACHS-2, the mortality mode had a C-statistic of 0.81 that improved to 0.83 with the addition of age. A final multivariable model inclusive of RACHS-2, age, payer, and presence of a complex chronic condition outside of congenital heart disease further improved model discrimination to 0.87 (P < 0.001). Discrimination in the validation cohort was also very good with a C-statistic of 0.83.

CONCLUSIONS

We created and validated a risk-adjustment model for CHS that accounts for patient and procedural characteristics associated with in-hospital mortality available in administrative data, including the newly developed RACHS-2. Our risk model will be critical for use in health services research and quality improvement initiatives.

Emergency Department Volume and Delayed Diagnosis of Pediatric Appendicitis: A Retrospective Cohort Study

OBJECTIVE

To determine the association of emergency department (ED) volume of children and delayed diagnosis of appendicitis.

BACKGROUND

Delayed diagnosis of appendicitis is common in children. The association between ED volume and delayed diagnosis is uncertain, but diagnosis-specific experience might improve diagnostic timeliness.

METHODS

Using Healthcare Cost and Utilization Project 8-state data from 2014 to 2019, we studied all children with appendicitis <18 years old in all EDs. The main outcome was probable delayed diagnosis: >75% likelihood that a delay occurred based on a previously validated measure. Hierarchical models tested associations between ED volumes and delay, adjusting for age, sex, and chronic conditions. We compared complication rates by delayed diagnosis occurrence.

RESULTS

Among 93,136 children with appendicitis, 3,293 (3.5%) had delayed diagnosis. Each 2-fold increase in ED volume was associated with a 6.9% (95% CI: 2.2, 11.3) decreased odds of delayed diagnosis. Each 2-fold increase in appendicitis volume was associated with a 24.1% (95% CI: 21.0, 27.0) decreased odds of delay. Those with delayed diagnosis were more likely to receive intensive care [odds ratio (OR): 1.81, 95% CI: 1.48, 2.21], have perforated appendicitis (OR: 2.81, 95% CI: 2.62, 3.02), undergo abdominal abscess drainage (OR: 2.49, 95% CI: 2.16, 2.88), have multiple abdominal surgeries (OR: 2.56, 95% CI: 2.13, 3.07), or develop sepsis (OR: 2.02, 95% CI: 1.61, 2.54).

CONCLUSIONS

Higher ED volumes were associated with a lower risk of delayed diagnosis of pediatric appendicitis. Delay was associated with complications.

Disparities in Management of Acute Gastroenteritis in Hospitalized Children

BACKGROUND AND OBJECTIVES

Acute gastroenteritis (AGE) is a common health care problem accounting for up to 200 000 pediatric hospitalizations annually. Previous studies show disparities in the management of children from different ethnic backgrounds presenting to the emergency department with AGE. Our aim was to evaluate whether differences in medical management also exist between Hispanic and non-Hispanic children hospitalized with AGE.

METHODS

We performed a single-center retrospective study of children aged 2 months to 12 years admitted to the pediatric hospital medicine service from January 2016 to December 2020 with a diagnosis of (1) acute gastroenteritis or (2) dehydration with feeding intolerance, vomiting, and/or diarrhea. Differences in clinical pathway use, diagnostic studies performed, and medical interventions ordered were compared between Hispanic and non-Hispanic patients.

RESULTS

Of 512 admissions, 54.9% were male, 51.6% were Hispanic, and 59.2% were on Medicaid. There was no difference between Hispanic and non-Hispanic patients in reported nausea or vomiting at admission, pathway use, or laboratory testing including stool studies. However, after adjusting for covariates, Hispanic patients had more ultrasound scans performed (odds ratio 1.65, 95% confidence interval 1.04-2.64) and fewer orders for antiemetics (odds ratio 0.53, 95% CI 0.29-0.95) than non-Hispanic patients.

CONCLUSIONS

Although there were no differences in many aspects of AGE management between Hispanic and non-Hispanic patients, there was still variability in ultrasound scans performed and antiemetics ordered, despite similarities in reported abdominal pain, nausea, and vomiting. Prospective and/or qualitative studies may be needed to clarify underlying reasons for these differences.

Risk Factors Associated With Development of Multiple-Organ Dysfunction Syndrome After Pediatric Drowning

OBJECTIVE

This study aimed to describe a single-center experience of pediatric drowning and to investigate risk factors associated with the development of pediatric multiple-organ dysfunction syndrome (MODS) after drowning events.

METHODS

A single-center retrospective case-control study was performed at a tertiary children's hospital examining patients aged 1 month to 25 years who were admitted to the pediatric intensive care unit after a drowning event. The study period was June 2016 to June 2021. Patients who developed MODS at day 1 of intensive care admission were compared with those who did not.

RESULTS

A total of 48 patients with a median age of 2.3 years were included. Twenty-nine (60%) had MODS at 24 hours. Those with MODS at 24 hours were more likely to require cardiopulmonary resuscitation (CPR), required longer duration of CPR, and had longer submersion times; otherwise, there were no differences in baseline characteristics. Those who developed MODS at 24 hours had longer lengths of stays, longer lengths of mechanical ventilation, and higher mortality. Multiple admission parameters were evaluated based on MODS-free survival at 24 hours. On univariable analysis, patients without MODS-free survival at 24 hours had higher rates of CPR, higher blood glucose on admission, higher illness severity scores, higher lactates, and lower Glasgow Coma Scale scores. A multivariable model was constructed using risk factors at presentation that were significant on univariable analysis; blood glucose greater than 200 mg/dL was associated with decreased odds of MODS-free survival at 24 hours after controlling for CPR administration of greater than 5 minutes and body temperature.

CONCLUSIONS

Development of MODS in pediatric drowning is associated with worse patient outcomes. Hyperglycemia was identified as a potentially modifiable risk factor for the development of MODS at 24 hours and could serve as a useful prognostic parameter in this unique patient population.

Characteristics, disposition, and outcomes of children hospitalized for mental health boarding at a children's hospital

Increasingly, youth experiencing mental health crises present to acute care medical hospitals and "board" on medical units due to inpatient psychiatric bed shortages. We conducted a retrospective cohort study of children experiencing mental health boarding at a US children's hospital from October 2020 to September 2022. We examined associations between patients' characteristics and their disposition and outcomes. Our cohort included 1891 boarding hospitalizations: 53.9% transferred to an inpatient psychiatric hospital and 46.1% discharged home. Characteristics associated with not being transferred to an inpatient psychiatric hospital included age <13 years (adjusted odds ratio [aOR] 0.6; 95% confidence interval [CI]: 0.4-0.7), disruptive or aggressive behavior (aOR 0.6; 95% CI: 0.4-0.8), psychosis (aOR 0.5; 95% CI: 0.3-0.8), COVID-19 infection (aOR 0.3; 95% CI: 0.2-0.6), or a complex chronic medical condition (aOR 0.8; 95% CI: 0.6-1.0). Our findings suggest that certain populations of children experiencing mental health boarding face disparate access to inpatient psychiatric care.

Social Determinants of Health Are Associated With Visits for Ambulatory Care Sensitive Conditions

OBJECTIVES

Population health experts have described the link between social factors and health, but few studies link specific social needs to disease processes. Nationwide Children's Hospital implemented a universal, annual screener for social determinants of health (SDH) in 2018. Early analyses have shown that patients identifying an SDH need were more likely to have an emergency department (ED) or inpatient stay. The objective of this study is to identify links between SDH and ED presentation for ambulatory care sensitive conditions (ACSCs).

METHODS

This was a retrospective observational study of children aged 0-21 years receiving care at Nationwide Children's Hospital from 2018 to 2021 that were screened for SDH. Acute care utilization within 6 months of screener completion, sociodemographic, and clinical data were collected via EPIC data extraction. Patients that completed screening tool for the first time in the ED were excluded to minimize selection bias. Logistic regression was used to analyze the association between ED presentation for ACSCs and SDH needs.

RESULTS

A total of 108,346 social determinants screeners were included with 9% of screeners identifying a need. Five percent of the population expressed food needs, 4% transportation needs, 3% utility needs, and 1% housing needs. Eighteen percent of patients had an ED visit for ACSC, with the most common complaints being upper respiratory infections and asthma. Having any SDH need was associated with ED visits for ACSCs (odds ratio, 1.12; 95% confidence interval, 1.06-1.18). Needs in all domains were significantly associated with increased visits for ACSCs; however, patients with housing needs had the highest odds of utilization (odds ratio, 1.25; confidence interval, 1.11-1.41).

CONCLUSIONS

The odds of ED presentation for ACSCs are higher in patients with expressed social needs. Further delineating the connections between specific SDH and health outcomes can inform timely and appropriate interventions.

Effectiveness of Monovalent mRNA Vaccines Against Omicron XBB Infection in Singaporean Children Younger Than 5 Years

Importance

Literature on vaccine effectiveness of SARS-CoV-2 messenger RNA (mRNA) vaccines for children younger than 5 years is limited.

Objective

To report the effectiveness of monovalent mRNA vaccines against SARS-CoV-2 infection among Singaporean children aged 1 through 4 years during a COVID-19 pandemic wave of the Omicron XBB variant.

Design, Setting, and Participants

This was a population-based cohort study, conducted over a 6-month study period from October 1, 2022, through March 31, 2023, after the implementation of community vaccination among all Singaporean children aged 1 through 4 years. The study period was dominated by the Omicron XBB subvariant.

Exposure

Receipt of SARS-CoV-2 mRNA vaccines.

Main Outcome Measure

Vaccine effectiveness against confirmed SARS-CoV-2 infection. The adjusted incidence rate ratio for confirmed infections using Poisson regression was reported, with the reference group being those who were unvaccinated. Analyses were stratified by prior documented SARS-CoV-2 infection.

Results

A total of 121 628 children (median [IQR] age, 3.1 [2.2-3.9] years; 61 925 male [50.9%]) were included in the study, contributing 21 015 956 person-days of observation. The majority of children (11 294 of 11 705 [96.5%]) received the mRNA-1273 COVID-19 vaccine (Moderna). Vaccine effectiveness against confirmed infection was 45.2% (95% CI, 24.7%-60.2%) in partially vaccinated, infection-naive children and 63.3% (95% CI, 40.6%-77.3%) in fully vaccinated, infection-naive children compared with the unvaccinated group. Among previously infected children, vaccine effectiveness against reinfections in those with at least 1 vaccine dose was estimated at 74.6% (95% CI, 38.7%-89.5%).

Conclusions and Relevance

Study results suggest that completion of a primary mRNA vaccine series provided protection against SARS-CoV-2 infection in children aged 1 through 4 years. Although incidence of hospitalization and severe illness is low in this age group, there is potential benefit of vaccination in preventing infection and potential sequelae.

Emergency Department Care for Children During the 2022 Viral Respiratory Illness Surge

Importance

Pediatric readiness is essential for all emergency departments (EDs). Children's experience of care may differ according to operational challenges in children's hospitals, community hospitals, and rural EDs caused by recurring and sometimes unpredictable viral illness surges.

Objective

To describe wait times, lengths of stay (LOS), and ED revisits across diverse EDs participating in a statewide quality collaborative during a surge in visits in 2022.

Design, Setting, and Participants

This retrospective cohort study included 25 EDs from the Michigan Emergency Department Improvement Collaborative data registry from January 1, 2021, through December 31, 2022. Pediatric (patient age <18 years) encounters for viral and respiratory conditions were analyzed, comparing wait times, LOS, and ED revisit rates for children's hospital, urban pediatric high-volume (≥10% of overall visits), urban pediatric low-volume (<10% of overall visits), and rural EDs.

Exposures

Surge in ED visit volumes for children with viral and respiratory illnesses from September 1 through December 31, 2022.

Main Outcomes and Measures

Prolonged ED visit wait times (arrival to clinician assigned, >4 hours), prolonged LOS (arrival to departure, >12 hours), and ED revisit rate (ED discharge and return within 72 hours).

Results

A total of 2 761 361 ED visits across 25 EDs in 2021 and 2022 were included. From September 1 to December 31, 2022, there were 301 688 pediatric visits for viral and respiratory illness, an increase of 71.8% over the 4 preceding months and 15.7% over the same period in 2021. At children's hospitals during the surge, 8.0% of visits had prolonged wait times longer than 4 hours, 8.6% had prolonged LOS longer than 12 hours, and 42 revisits occurred per 1000 ED visits. Prolonged wait times were rare among other sites. However, prolonged LOS affected 425 visits (2.2%) in urban high-pediatric volume EDs, 133 (2.6%) in urban pediatric low-volume EDs, and 176 (3.1%) in rural EDs. High visit volumes were associated with increased ED revisits across sites.

Conclusions and Relevance

In this cohort study of more than 2.7 million ED visits, a pediatric viral illness surge was associated with different pediatric acute care across EDs in the state. Clinical management pathways and quality improvement efforts may more effectively mitigate dangerous clinical conditions with strong collaborative relationships across EDs and setting of care.

Nationwide epidemiology and clinical practice patterns of pediatric urinary tract infections: application of multivariate time-series clustering

BACKGROUND

The nationwide epidemiology and clinical practice patterns for younger children hospitalized with urinary tract infections (UTIs) were unclear.

METHODS

We conducted a retrospective observational study consisting of 32,653 children aged < 36 months who were hospitalized with UTIs from 856 medical facilities during fiscal years 2011-2018 using a nationally representative inpatient database in Japan. We investigated the epidemiology of UTIs and changes in clinical practice patterns (e.g., antibiotic use) over 8 years. A machine learning algorithm of multivariate time-series clustering with dynamic time warping was used to classify the hospitals based on antibiotic use for UTIs.

RESULTS

We observed marked male predominance among children aged < 6 months, slight female predominance among children aged > 12 months, and summer seasonality among children hospitalized with UTIs. Most physicians selected intravenous second- or third-generation cephalosporins as the empiric therapy for treating UTIs, which was switched to oral antibiotics during hospitalizations for 80% of inpatients. Whereas total antibiotic use was constant over the 8 years, broad-spectrum antibiotic use decreased gradually from 5.4 in 2011 to 2.5 days of therapy per 100 patient-days in 2018. The time-series clustering distinctively classified 5 clusters of hospitals based on antibiotic use patterns and identified hospital clusters that preferred to use broad-spectrum antibiotics (e.g., antipseudomonal penicillin and carbapenem).

CONCLUSIONS

Our study provided novel insight into the epidemiology and practice patterns for pediatric UTIs. Time-series clustering can be useful to identify the hospitals with aberrant practice patterns to further promote antimicrobial stewardship. A higher resolution version of the Graphical abstract is available as Supplementary information.

Factors Associated With Actionable Gastrointestinal Panel Results in Hospitalized Children

OBJECTIVES

There is uncertainty regarding which hospitalized patients with acute gastroenteritis (AGE) benefit from gastrointestinal panel (GIP) testing. Unnecessary testing may lead to increased costs, overdiagnosis, and overtreatment. In general, AGE management and outcomes are most impacted if an actionable (bacterial or parasitic) result is obtained. We aimed to assess which clinical reasons for ordering GIP testing ("order indications") and patient factors were associated with actionable results.

METHODS

This is a cross-sectional study of pediatric patients hospitalized between 2015 and 2018 at a large pediatric health care system with diarrhea and a GIP performed. Multivariable regression analysis was used to determine associations between actionable GIP results and order indication, stool frequency, and demographics. Findings were evaluated in patients with complex chronic conditions (CCC) and non-CCC patients.

RESULTS

There were 1124 GIPs performed in 967 encounters. Non-CCC patients had more actionable results than CCC patients, and reasons for testing differed. Across both cohorts, age ≥1 year old was positively associated with actionable results. For non-CCC patients, actionable results were associated with "diarrhea with blood or pus" order indication and nonwinter season; international travel was associated with non-Clostridioides difficile bacteria and parasites. No order indications were associated with actionable results for CCC patients.

CONCLUSIONS

Patient factors and order indications that may help identify children hospitalized for AGE with actionable GIP results include older age (regardless of CCC status), as well as bloody stools and international travel in previously healthy children. Prospective validation of these findings could help improve diagnostic stewardship and decrease unnecessary testing.

Patterns of Mental Health Service Use During the Transition to Adulthood Among Autistic Adolescents and Young Adults

Background

The time of transition into adulthood, especially when leaving school, is a time when many autistic adolescents and young adults (AYA) may stop receiving mental health services that they have relied on, leading to worse mental health outcomes. The purpose of this study was to describe patterns of mental health service use during transition to adulthood among autistic AYAs.

Methods

We performed a cross-sectional study using electronic health records from years 2015 to 2019 from one large university health care system. We included autistic individuals ages 11-27 with at least one clinical encounter annually in the cohort. Outcomes included psychotropic medications and psychotherapy received, psychotropic polypharmacy, psychiatric emergency department (ED) visits, and adverse drug events.

Results

Almost half of the 529 patients in the cohort received polypharmacy. The most common treatment was medication only (56.9%), followed by no treatment (22.7%), medication plus psychotherapy (18.7%), and psychotherapy only (data masked). The 17-21 age group had the highest odds of a psychiatric ED visit, whereas the 22-27 age group had the highest odds of receiving psychotropic medications and polypharmacy. Black AYA were more likely to receive psychotherapy and less likely to receive psychotropic polypharmacy than non-Hispanic Whites.

Conclusion

Autistic individuals may benefit from more support from the health care system for their transition into adulthood to maintain use of beneficial mental health services as they leave school and to reduce the frequency of adverse outcomes. Access to providers experienced treating the complex needs of autistic individuals is important to reduce disparities.
