PECARN prediction rule for cervical spine imaging of children presenting to the emergency department with blunt trauma: a multicentre prospective observational study.

BACKGROUND: Cervical spine injuries in children are uncommon but potentially devastating; however, indiscriminate neck imaging after trauma unnecessarily exposes children to ionising radiation. The aim of this study was to derive and validate a paediatric clinical prediction rule that can be incorporated into an algorithm to guide radiographic screening for cervical spine injury among children in the emergency department. METHODS: In this prospective observational cohort study, we screened children aged 0-17 years presenting with known or suspected blunt trauma at 18 specialised children's emergency departments in hospitals in the USA affiliated with the Pediatric Emergency Care Applied Research Network (PECARN). Injured children were eligible for enrolment into derivation or validation cohorts by fulfilling one of the following criteria: transported from the scene of injury to the emergency department by emergency medical services; evaluated by a trauma team; and undergone neck imaging for concern for cervical spine injury either at or before arriving at the PECARN-affiliated emergency department. Children presenting with solely penetrating trauma were excluded. Before viewing an enrolled child's neck imaging results, the attending emergency department clinician completed a clinical examination and prospectively documented cervical spine injury risk factors in an electronic questionnaire. Cervical spine injuries were determined by imaging reports and telephone follow-up with guardians within 21-28 days of the emergency room encounter, and cervical spine injury was confirmed by a paediatric neurosurgeon. Factors associated with a high risk of cervical spine injury (>10%) were identified by bivariable Poisson regression with robust error estimates, and factors associated with non-negligible risk were identified by classification and regression tree (CART) analysis. Variables were combined in the cervical spine injury prediction rule. The primary outcome of interest was cervical spine injury within 28 days of initial trauma warranting inpatient observation or surgical intervention. Rule performance measures were calculated for both derivation and validation cohorts. A clinical care algorithm for determining which risk factors warrant radiographic screening for cervical spine injury after blunt trauma was applied to the study population to estimate the potential effect on reducing CT and x-ray use in the paediatric emergency department. This study is registered with ClinicalTrials.gov, NCT05049330. FINDINGS: Nine emergency departments participated in the derivation cohort, and nine participated in the validation cohort. In total, 22 430 children presenting with known or suspected blunt trauma were enrolled (11 857 children in the derivation cohort; 10 573 in the validation cohort). 433 (1·9%) of the total population had confirmed cervical spine injuries. The following factors were associated with a high risk of cervical spine injury: altered mental status (Glasgow Coma Scale [GCS] score of 3-8 or unresponsive on the Alert, Verbal, Pain, Unresponsive scale [AVPU] of consciousness); abnormal airway, breathing, or circulation findings; and focal neurological deficits including paresthesia, numbness, or weakness. Of 928 in the derivation cohort presenting with at least one of these risk factors, 118 (12·7%) had cervical spine injury (risk ratio 8·9 [95% CI 7·1-11·2]). The following factors were associated with non-negligible risk of cervical spine injury by CART analysis: neck pain; altered mental status (GCS score of 9-14; verbal or pain on the AVPU; or other signs of altered mental status); substantial head injury; substantial torso injury; and midline neck tenderness. The high-risk and CART-derived factors combined and applied to the validation cohort performed with 94·3% (95% CI 90·7-97·9) sensitivity, 60·4% (59·4-61·3) specificity, and 99·9% (99·8-100·0) negative predictive value. Had the algorithm been applied to all participants to guide the use of imaging, we estimated the number of children having CT might have decreased from 3856 (17·2%) to 1549 (6·9%) of 22 430 children without increasing the number of children getting plain x-rays. INTERPRETATION: Incorporated into a clinical algorithm, the cervical spine injury prediction rule showed strong potential for aiding clinicians in determining which children arriving in the emergency department after blunt trauma should undergo radiographic neck imaging for potential cervical spine injury. Implementation of the clinical algorithm could decrease use of unnecessary radiographic testing in the emergency department and eliminate high-risk radiation exposure. Future work should validate the prediction rule and care algorithm in more general settings such as community emergency departments.

A risk-based monitoring approach to source data monitoring and documenting monitoring findings.

BACKGROUND: Clinical trial monitoring is evolving from labor-intensive to targeted approaches. The traditional 100% Source Data Monitoring (SDM) approach fails to prioritize data by significance, diverting attention from critical elements. Despite regulatory guidance on Risk-Based Monitoring (RBM), its widespread implementation has been slow. METHODS: Our study teams assess the study's overall risk, document heightened and critical risks, and create a study-specific risk-based monitoring plan, integrating SDM and Central Data Monitoring (CDM). SDM combines a fixed list of pre-identified variables and a list of randomly identified variables to monitor. Identifying variables follows a two-step approach: first, a random sample of participants is selected, second, a random set of variables for each participant selected is identified. Sampling weights prioritize critical variables. Regular team meetings are held to discuss and compile significant findings into a Study Monitoring Report. RESULTS: We present a random SDM sample and a Study Monitoring Report. The random SDM output includes a look-up table for selected database elements. The report provides a holistic view of the study issues and overall health. CONCLUSIONS: The proposed random sampling method is used to monitor a representative set of critical variables, while the Study Monitoring Report is written to summarize significant monitoring findings and data trends. The report allows the sponsor to assess the current status of the study and data effectively. Communicating and sharing emerging insights facilitates timely adjustments of future monitoring activities, optimizing efficiencies, and study outcomes.

Pediatric mental health emergency department visits from 2017 to 2022: A multicenter study.

BACKGROUND: The COVID-19 pandemic adversely affected children's mental health (MH) and changed patterns of MH emergency department (ED) utilization. Our objective was to assess how pediatric MH ED visits during the COVID-19 pandemic differed from expected prepandemic trends. METHODS: We retrospectively studied MH ED visits by children 5 to <18 years old at nine U.S. hospitals participating in the Pediatric Emergency Care Applied Research Network Registry from 2017 to 2022. We described visit length by time period: prepandemic (January 2017-February 2020), early pandemic (March 2020-December 2020), midpandemic (2021), and late pandemic (2022). We estimated expected visit rates from prepandemic data using multivariable Poisson regression models. We calculated rate ratios (RRs) of observed to expected visits per 30 days during each pandemic time period, overall and by sociodemographic and clinical characteristics. RESULTS: We identified 175,979 pediatric MH ED visits. Visit length exceeded 12 h for 7.3% prepandemic, 8.4% early pandemic, 15.0% midpandemic, and 19.2% late pandemic visits. During the early pandemic, observed visits per 30 days decreased relative to expected rates (RR 0.80, 95% confidence interval [CI] 0.78-0.84), were similar to expected rates during the midpandemic (RR 1.01, 95% CI 0.96-1.07), and then decreased below expected rates during the late pandemic (RR 0.92, 95% CI 0.86-0.98). During the late pandemic, visit rates were higher than expected for females (RR 1.10, 95% CI 1.02-1.20) and for bipolar disorders (RR 1.83, 95% CI 1.38-2.75), schizophrenia spectrum disorders (RR 1.55, 95% CI 1.10-2.59), and substance-related and addictive disorders (RR 1.50, 95% CI 1.18-2.05). CONCLUSIONS: During the late pandemic, pediatric MH ED visits decreased below expected rates; however, visits by females and for specific conditions remained elevated, indicating a need for increased attention to these groups. Prolonged ED visit lengths may reflect inadequate availability of MH services.

Harmonizing federal interagency traumatic brain injury research data to examine depression and suicide-related outcomes.

OBJECTIVE: This proof-of-concept study was conducted to establish the feasibility of compiling Federal Interagency Traumatic Brain Injury Research (FITBIR) data pertaining to depression and suicide risk, with the secondary goal of improving understanding regarding these outcomes. FITBIR is a national repository of participant-level traumatic brain injury (TBI) data designed to address methodological limitations (e.g., small sample size, heterogeneity of injuries). METHOD: FITBIR studies with TBI severity and measures related to depression and suicidal ideation were identified. Data were harmonized across relevant studies and grouped to identify "probable depression" and suicidal ideation, resulting in a large, combined sample. Rates of probable depression and suicidal ideation were described across the available studies, considering the influence of demographic and/or injury-related factors on outcomes. RESULTS: Cross-sectional studies meeting criteria included four studies with depression outcomes and two with suicidal ideation outcomes. Two studies reported data appropriate for comparative analyses on depression. Combined results suggested that approximately 71% of participants were categorized as having probable depression. Participants with a history of mild TBI had 2.54 greater odds of probable depression (95% confidence interval [1.93, 3.34]) than those without a history of TBI. CONCLUSIONS: Methods, harmonization code, and meta-databases related to TBI, probable depression, and suicidal ideation are now publicly available on the FITBIR website. Even with limited data, harmonization of FITBIR studies can serve as the basis for ongoing TBI and mental health research. Analyses will be more robust in the future as more studies with relevant outcome data are added to the FITBIR database. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Probabilistic Linkage Creates a Novel Database to Study Bronchiolitis Care in the PICU.

OBJECTIVES: Lack of a comprehensive database containing diagnosis, patient and clinical characteristics, diagnostics, treatments, and outcomes limits needed comparative effectiveness research (CER) to improve care in the PICU. Combined, the Pediatric Hospital Information System (PHIS) and Virtual Pediatric Systems (VPS) databases contain the needed data for CER, but limits on the use of patient identifiers have thus far prevented linkage of these databases with traditional linkage methods. Focusing on the subgroup of patients with bronchiolitis, we aim to show that probabilistic linkage methods accurately link data from PHIS and VPS without the need for patient identifiers to create the database needed for CER. METHODS: We used probabilistic linkage to link PHIS and VPS records for patients admitted to a tertiary children's hospital between July 1, 2017 to June 30, 2019. We calculated the percentage of matched records, rate of false-positive matches, and compared demographics between matched and unmatched subjects with bronchiolitis. RESULTS: We linked 839 of 920 (91%) records with 4 (0.5%) false-positive matches. We found no differences in age (P = .76), presence of comorbidities (P = .16), admission illness severity (P = .44), intubation rate (P = .41), or PICU stay length (P = .36) between linked and unlinked subjects. CONCLUSIONS: Probabilistic linkage creates an accurate and representative combined VPS-PHIS database of patients with bronchiolitis. Our methods are scalable to join data from the 38 hospitals that jointly contribute to PHIS and VPS, creating a national database of diagnostics, treatment, outcome, and patient and clinical data to enable CER for bronchiolitis and other conditions cared for in the PICU.

Prevalence, Demographic, and Clinical Factors Associated With Cognitive Dysfunction in Patients With Neuromyelitis Optica Spectrum Disorder.

BACKGROUND AND OBJECTIVES: Neuromyelitis optica spectrum disorder (NMOSD) is a chronic CNS demyelinating autoimmune disorder targeting the astrocyte antigen aquaporin-4 (AQP4), typically presenting with optic neuritis, transverse myelitis, and brain syndromes. Cognitive dysfunction (CD) in NMOSD is under-recognized and poorly understood. The purpose of this study was to evaluate the prevalence and clinical variables associated with CD in NMOSD. METHODS: This observational retrospective study with longitudinal follow-up describes a clinical cohort seen in the Collaborative International Research in Clinical and Longitudinal Experience Study in NMOSD. Serial Montreal Cognitive Assessments (MoCAs) were performed upon enrollment and at 6-month intervals to evaluate longitudinal cognitive function relative to demographic and disease-related factors. We used 2-tailed t test, analysis of variance, the χ2 test, linear regression for univariable and adjusted analyses and simultaneous linear regression and mixed-effects model for multivariable analyses. RESULTS: Thirty-four percent (75/219) of patients met criteria for CD (MoCA <26); 29% (64/219) showed mild dysfunction (MoCA 20-26/30), and 5% (11/219) showed moderate (MoCA <20/30) dysfunction. Patients with less neurologic disability and lower pain scores had higher MoCA scores (95% CI 0.24-0.65 and 95% CI 0.09-0.42, respectively). Patients with at least high school education scored higher on the MoCA (95% CI 2.2-5). When comparing patients dichotomized for CD, patients never on rituximab scored higher than patients only treated with rituximab (p < 0.029). There was no significant association between annualized relapse rate, age, sex, disease duration, AQP4 serostatus or brain lesions, and CD. CD was more pronounced among Black than White patients (95% CI -2.7 to -0.7). Multivariable analysis of serial MoCA did not indicate change (p = 0.715). Descriptive analysis of serial MoCA showed 30% (45/150) of patients with worsening MoCA performance had impaired language and verbal recall. DISCUSSION: To our knowledge, this is the largest study of diverse cohort to investigate CD in patients with NMOSD. Our findings demonstrate 34% of patients with NMOSD experience mild-to-moderate CD, while 30% of patients demonstrated decline on serial testing. The substantial prevalence of CD in this pilot report highlights the need for improved and validated screening tools and comprehensive measures to investigate CD in NMOSD.

Grieving Children' Death in an Intensive Care Unit: Implementation of a Standardized Process.

Background: The grief that accompanies witnessing the death of a child puts health care professionals at risk of secondary trauma, burnout, and turnover when left unaddressed. Objective: Support staff well-being and promote resiliency. Methods: Descriptive implementation of a structured, peer-to-peer bereavement support program for intensive care unit (ICU) staff at a tertiary children's hospital. Results: Thirty-five virtual sessions were held over the period of one year.Through these sessions, participants shared perspectives and normalized reactions, and explored potential coping strategies. Post-session feedback surveys demonstrated the negative impact of a death on the personal or work life of ICU staff. Additionally, nearly all reported some level of burnout. Conclusions: The sessions were feasible and positively impacted staff coping and well-being. Barriers and facilitators to session attendance, as well as suggestions for improvement, were also explored. Implications for practice and future research are discussed. No clinical trial registration is applicable.

CARE4Kids Study: Endophenotypes of Persistent Post-Concussive Symptoms in Adolescents: Study Rationale and Protocol.

Treatment of youth concussion during the acute phase continues to evolve, and this has led to the emergence of guidelines to direct care. While symptoms after concussion typically resolve in 14-28 days, a portion (∼20%) of adolescents endorse persistent post-concussive symptoms (PPCS) beyond normal resolution. This report outlines a study implemented in response to the National Institute of Neurological Diseases and Stroke call for the development and initial clinical validation of objective biological measures to predict risk of PPCS in adolescents. We describe our plans for recruitment of a Development cohort of 11- to 17-year-old youth with concussion, and collection of autonomic, neurocognitive, biofluid, and imaging biomarkers. The most promising of these measures will then be validated in a separate Validation cohort of youth with concussion, and a final, clinically useful algorithm will be developed and disseminated. Upon completion of this study, we will have generated a battery of measures predictive of high risk for PPCS, which will allow for identification and testing of interventions to prevent PPCS in the most high-risk youth.

Pediatric Firearm Injury Emergency Department Visits From 2017 to 2022: A Multicenter Study.

BACKGROUND AND OBJECTIVE: Pediatric firearm injuries increased during the coronavirus disease 2019 pandemic, but recent trends in firearm injury emergency department (ED) visits are not well described. We aimed to assess how pediatric firearm injury ED visits during the pandemic differed from expected prepandemic trends. METHODS: We retrospectively studied firearm injury ED visits by children <18 years old at 9 US hospitals participating in the Pediatric Emergency Care Applied Research Network Registry before (January 2017 to February 2020) and during (March 2020 to November 2022) the pandemic. Multivariable Poisson regression models estimated expected visit rates from prepandemic data. We calculated rate ratios (RRs) of observed to expected visits per 30 days, overall, and by sociodemographic characteristics. RESULTS: We identified 1904 firearm injury ED visits (52.3% 15-17 years old, 80.0% male, 63.5% non-Hispanic Black), with 694 prepandemic visits and 1210 visits during the pandemic. Death in the ED/hospital increased from 3.1% prepandemic to 6.1% during the pandemic (P = .007). Firearm injury visits per 30 days increased from 18.0 prepandemic to 36.1 during the pandemic (RR 2.09, 95% CI 1.63-2.91). Increases beyond expected rates were seen for 10- to 14-year-olds (RR 2.61, 95% CI 1.69-5.71), females (RR 2.46, 95% CI 1.55-6.00), males (RR 2.00, 95% CI 1.53-2.86), Hispanic children (RR 2.30, 95% CI 1.30-9.91), and Black non-Hispanic children (RR 1.88, 95% CI 1.34-3.10). CONCLUSIONS: Firearm injury ED visits for children increased beyond expected prepandemic trends, with greater increases among certain population subgroups. These findings may inform firearm injury prevention efforts.

Relation of Aerobic Activity to Cognition and Well-being in Chronic Mild Traumatic Brain Injury: A LIMBIC-CENC Study.

INTRODUCTION: Because chronic difficulties with cognition and well-being are common after mild traumatic brain injury (mTBI) and aerobic physical activity and exercise (PAE) is a potential treatment and mitigation strategy, we sought to determine their relationship in a large sample with remote mTBI. MATERIALS AND METHODS: The Long-Term Impact of Military-Relevant Brain Injury Consortium-Chronic Effects of Neurotrauma Consortium prospective longitudinal study is a national multicenter observational study of combat-exposed service members and veterans. Study participants with positive mTBI histories (n = 1,087) were classified as "inactive" (23%), "insufficiently active" (46%), "active" (19%), or "highly active" (13%) based on the aerobic PAE level. The design was a cross-sectional analysis with multivariable regression. PAE was reported on the Behavioral Risk Factor Surveillance System. Preselected primary outcomes were seven well-validated cognitive performance tests of executive function, learning, and memory: The California Verbal Learning Test-Second Edition Long-Delay Free Recall and Total Recall, Brief Visuospatial Memory Test-Revised Total Recall, Trail-Making Test-Part B, and NIH Toolbox for the Assessment of Neurological Behavior and Function Cognition Battery Picture Sequence Memory, Flanker, and Dimensional Change Card Sort tests. Preselected secondary outcomes were standardized self-report questionnaires of cognitive functioning, life satisfaction, and well-being. RESULTS: Across the aerobic activity groups, cognitive performance tests were not significantly different. Life satisfaction and overall health status scores were higher for those engaging in regular aerobic activity. Exploratory analyses also showed better working memory and verbal fluency with higher aerobic activity levels. CONCLUSIONS: An association between the aerobic activity level and the preselected primary cognitive performance outcome was not demonstrated using this study sample and methods. However, higher aerobic activity levels were associated with better subjective well-being. This supports a clinical recommendation for regular aerobic exercise among persons with chronic or remote mTBI. Future longitudinal analyses of the exercise-cognition relationship in chronic mTBI populations are recommended.

Health Care Provider Bias in Estimating the Health Literacy of Caregivers in a Pediatric Emergency Department.

BACKGROUND: Health literacy is a growing concern because of its effects on communication and health outcomes. One aspect of this communication is the ability of the health care provider to estimate the health literacy of a patient or their caregiver. The objectives of this study are to quantify misestimation of caregiver health literacy by providers and identify potential descriptive or demographic factors that might be related to those misestimations. METHODS: Providers were asked to perceive descriptive factors and estimate the health literacy of caregivers in a pediatric Emergency Department. Then, the health literacy of the caregiver was tested using the Short Assessment of Health Literacy, and cross-tabulated with provider estimates. RESULTS: Providers correctly estimated the health literacy of the caregivers 60% of the time, and misestimates were often underestimates (27.7%) rather than overestimates (12.3%). Providers overestimated the health literacy of 24.1% of fathers and only 9.8% of mothers (P = 0.012). They correctly estimated the health literacy of 63.9% of English-speaking caregivers compared with 30.6% of Spanish-speaking caregivers, and underestimated the health literacy of 50% of Spanish-speaking caregivers and 24.8% of English-speaking caregivers (P < 0.001). Providers correctly estimated the health literacy of 34.4% of racially and ethnically diverse caregivers compared with 71.5% of White/non-Hispanic caregivers. They underestimated the health literacy of 52.1% of these racially and ethnically diverse caregivers and 16.8% of White/non-Hispanic caregivers (P < 0.001). CONCLUSIONS: Providers often overestimate and underestimate the health literacy of parents in the pediatric emergency department. Misestimates are related to race, caregiver role, and language spoken by the caregiver. When providers misestimate health literacy, they may use words or phrases that are above or below the health literacy level of the caregiver. These results suggest a need for further health literacy research and interventions in provider education and clinical practice.

Return visit rates after an emergency department discharge for children with sickle cell pain episodes.

BACKGROUND: High return visit rates after hospitalization for people with sickle cell disease (SCD) have been previously established. Due to a lack of multicenter emergency department (ED) return visit rate data, the return visit rate following ED discharge for pediatric SCD pain treatment is currently unknown. PROCEDURE: A seven-site retrospective cohort study of discharged ED visits for pain by children with SCD was conducted using the Pediatric Emergency Care Applied Research Network Registry. Visits between January 2017 and November 2021 were identified using previously validated criteria. The primary outcome was the 14-day return visit rate, with 3- and 7-day rates also calculated. Modified Poisson regression was used to analyze associations for age, sex, initial hospitalization rate, and a visit during the COVID-19 pandemic with return visit rates. RESULTS: Of 2548 eligible ED visits, approximately 52% were patients less than 12 years old, 50% were female, and over 95% were non-Hispanic Black. The overall 14-day return visit rate was 29.1% (95% confidence interval [CI]: 27.4%-30.9%; site range 22.7%-31.7%); the 7- and 3-day return visit rates were 23.0% (95% CI: 21.3%-24.6%) and 16.7% (95% CI: 15.3%-18.2%), respectively. Younger children had slightly lower 14-day return visit rates (27.3% vs. 31.1%); there were no associations for site hospitalization rate, sex, and a visit occurring during the pandemic with 14-day returns. CONCLUSION: Nearly 30% of ED discharged visits after SCD pain treatment had a return visit within 14 days. Increased efforts are needed to identify causes for high ED return visit rates and ensure optimal ED and post-ED care.

National Assessment of Pediatric Readiness of US Emergency Departments During the COVID-19 Pandemic.

Importance: The National Pediatric Readiness Project assessment provides a comprehensive evaluation of the readiness of US emergency departments (EDs) to care for children. Increased pediatric readiness has been shown to improve survival for children with critical illness and injury. Objectives: To complete a third assessment of pediatric readiness of US EDs during the COVID-19 pandemic, to examine changes in pediatric readiness from 2013 to 2021, and to evaluate factors associated with current pediatric readiness. Design, Setting, and Participants: In this survey study, a 92-question web-based open assessment of ED leadership in US hospitals (excluding EDs not open 24 h/d and 7 d/wk) was sent via email. Data were collected from May to August 2021. Main Outcomes and Measures: Weighted pediatric readiness score (WPRS) (range, 0-100, with higher scores indicating higher readiness); adjusted WPRS (ie, normalized to 100 points), calculated excluding points received for presence of a pediatric emergency care coordinator (PECC) and quality improvement (QI) plan. Results: Of the 5150 assessments sent to ED leadership, 3647 (70.8%) responded, representing 14.1 million annual pediatric ED visits. A total of 3557 responses (97.5%) contained all scored items and were included in the analysis. The majority of EDs (2895 [81.4%]) treated fewer than 10 children per day. The median (IQR) WPRS was 69.5 (59.0-84.0). Comparing common data elements from the 2013 and 2021 NPRP assessments demonstrated a reduction in median WPRS (72.1 vs 70.5), yet improvements across all domains of readiness were noted except in the administration and coordination domain (ie, PECCs), which significantly decreased. The presence of both PECCs was associated with a higher adjusted median (IQR) WPRS (90.5 [81.4-96.4]) compared with no PECC (74.2 [66.2-82.5]) across all pediatric volume categories (P < .001). Other factors associated with higher pediatric readiness included a full pediatric QI plan vs no plan (adjusted median [IQR] WPRS: 89.8 [76.9-96.7] vs 65.1 [57.7-72.8]; P < .001) and staffing with board-certified emergency medicine and/or pediatric emergency medicine physicians vs none (median [IQR] WPRS: 71.5 [61.0-85.1] vs 62.0 [54.3-76.0; P < .001). Conclusions and Relevance: These data demonstrate improvements in key domains of pediatric readiness despite losses in the health care workforce, including PECCs, during the COVID-19 pandemic, and suggest organizational changes in EDs to maintain pediatric readiness.

Undertriage for Children With Caregivers Preferring Languages Other Than English.

OBJECTIVES: Undertriage, the underestimation of acuity, can result in delayed care and potential morbidity in the emergency department (ED). Although inequities in ED care based on language preference have been noted, little is known about its association with undertriage. We evaluated for differences in undertriage based on caregiver language preference. METHODS: This was a retrospective cross-sectional study of patients aged younger than 21 years, triaged as Emergency Severity Index (ESI) level 4 or 5 (nonurgent), to the pediatric ED from January 1, 2019, through January 31, 2021. Indicators of undertriage were defined as hospital admission, significant ED resource use, or return visits with admission. We used logistic regression with generalized estimating equations to measure the association of preferred language with undertriage. RESULTS: Of 114 266 ED visits included in the study, 22 525 (19.8%) represented patients with caregivers preferring languages other than English. These children were more likely to experience undertriage compared with those with caregivers preferring English (3.7% [English] versus 4.6% [Spanish] versus 5.9% [other languages]; Spanish versus English: odds ratio [OR], 1.3; 95% confidence interval [CI], 1.2-1.4] and other languages versus English: OR, 1.6; 95% CI, 1.2-2.2). Differences remained after adjusting for sex, insurance, mode of arrival, and clustering by triage nurse (Spanish versus English: adjusted OR, 1.3; 95% CI, 1.3-1.5) and other languages versus English: adjusted OR, 1.6; 95% CI, 1.2-2.2). CONCLUSIONS: Children accompanied by caregivers preferring languages other than English are more likely to be undertriaged in the pediatric ED. Efforts to improve the triage process are needed to promote equitable care for this population.

Timing of Pediatric Palliative Care Consults in Hospitalized Patients with Heart Disease.

Pediatric palliative care (PPC) provides an extra layer of support for families caring for a child with complex heart disease as these patients often experience lifelong morbidities with frequent hospitalizations and risk of early mortality. PPC referral at the time of heart disease diagnosis provides early involvement in the disease trajectory, allowing PPC teams to longitudinally support patients and families with symptom management, complex medical decision-making, and advanced care planning. We analyzed 113 hospitalized pediatric patients with a primary diagnosis of heart disease and a PPC consult to identify timing of first PPC consultation in relation to diagnosis, complex chronic conditions (CCC), and death. The median age of heart disease diagnosis was 0 days with a median of two CCCs while PPC consultation did not occur until a median age of 77 days with a median of four CCCs. Median time between PPC consult and death was 33 days (interquartile range: 7-128). Death often occurred in the intensive care unit ( n = 36, 67%), and the most common mode was withdrawal of life-sustaining therapies ( n = 31, 57%). PPC referral often occurred in the context of medical complexity and prolonged hospitalization. Referral close to the time of heart disease diagnosis would allow patients and families to fully utilize PPC benefits that exist outside of end-of-life care and may influence the mode and location of death. PPC consultation should be considered at the time of heart disease diagnosis, especially in neonates and infants with CCCs.

Diagnostic value of intereye difference metrics for optic neuritis in aquaporin-4 antibody seropositive neuromyelitis optica spectrum disorders.

BACKGROUND: The novel optic neuritis (ON) diagnostic criteria include intereye differences (IED) of optical coherence tomography (OCT) parameters. IED has proven valuable for ON diagnosis in multiple sclerosis but has not been evaluated in aquaporin-4 antibody seropositive neuromyelitis optica spectrum disorders (AQP4+NMOSD). We evaluated the diagnostic accuracy of intereye absolute (IEAD) and percentage difference (IEPD) in AQP4+NMOSD after unilateral ON >6 months before OCT as compared with healthy controls (HC). METHODS: Twenty-eight AQP4+NMOSD after unilateral ON (NMOSD-ON), 62 HC and 45 AQP4+NMOSD without ON history (NMOSD-NON) were recruited by 13 centres as part of the international Collaborative Retrospective Study on retinal OCT in Neuromyelitis Optica study. Mean thickness of peripapillary retinal nerve fibre layer (pRNFL) and macular ganglion cell and inner plexiform layer (GCIPL) were quantified by Spectralis spectral domain OCT. Threshold values of the ON diagnostic criteria (pRNFL: IEAD 5 µm, IEPD 5%; GCIPL: IEAD: 4 µm, IEPD: 4%) were evaluated using receiver operating characteristics and area under the curve (AUC) metrics. RESULTS: The discriminative power was high for NMOSD-ON versus HC for IEAD (pRNFL: AUC 0.95, specificity 82%, sensitivity 86%; GCIPL: AUC 0.93, specificity 98%, sensitivity 75%) and IEPD (pRNFL: AUC 0.96, specificity 87%, sensitivity 89%; GCIPL: AUC 0.94, specificity 96%, sensitivity 82%). The discriminative power was high/moderate for NMOSD-ON versus NMOSD-NON for IEAD (pRNFL: AUC 0.92, specificity 77%, sensitivity 86%; GCIP: AUC 0.87, specificity 85%, sensitivity 75%) and for IEPD (pRNFL: AUC 0.94, specificity 82%, sensitivity 89%; GCIP: AUC 0.88, specificity 82%, sensitivity 82%). CONCLUSIONS: Results support the validation of the IED metrics as OCT parameters of the novel diagnostic ON criteria in AQP4+NMOSD.

Clinical and epidemiological correlates of treatment change in patients with NMOSD: insights from the CIRCLES cohort.

OBJECTIVE: Neuromyelitis optica spectrum disorders (NMOSD) represent rare autoimmune diseases of the central nervous system largely targeting optic nerve(s) and spinal cord. The present analysis used real-world data to identify clinical and epidemiological correlates of treatment change in patients with NMOSD. METHODS: CIRCLES is a longitudinal, observational study of NMOSD conducted at 15 centers across North America. Patients with ≥ 60 days of follow-up and receiving on-study maintenance treatment were evaluated. The mean annual relapse rate (ARR) was estimated using negative binomial models; the likelihood of treatment change was estimated using Cox proportional hazards models. Relapses were included as time-varying covariates to estimate the relationship to treatment change. RESULTS: Of 542 patients included, 171 (31.5%) experienced ≥ 1 relapse on the study and 133 patients (24.5%) had ≥ 1 change in the treatment regimen. Two categories of variables significantly correlated with the likelihood of treatment change: (1) relapse: any on-study relapse (hazard ratio [HR] = 2.91; p < 0.001), relapse phenotypes (HR range = 2.15-5.49; p < 0.001), and pre-study ARR > 0.75 (HR 2.28; p < 0.001); 2) disease phenotype: brain syndrome only vs transverse myelitis involvement at onset (HR 2.44; p = 0.008), disease duration < 1 vs > 5 years (HR 1.66; p = 0.028), or autoimmune comorbidity (HR 1.55; p = 0.015). A subset of these factors significantly correlated with shorter time to first rituximab discontinuation. CONCLUSIONS: In CIRCLES, relapse patterns and disease phenotype significantly correlated with changes in the maintenance treatment regimen. Such findings may facilitate the identification of patients with NMOSD who are likely to benefit from treatment change to reduce relapse risk or disease burden and enhance the quality of life.

Extracorporeal membrane oxygenation and paediatric palliative care in an ICU.

OBJECTIVES: Compare rates, clinical characteristics, and outcomes of paediatric palliative care consultation in children supported on extracorporeal membrane oxygenation admitted to a single-centre 16-bed cardiac or a 28-bed paediatric ICU. METHODS: Retrospective review of clinical characteristics and outcomes of children (aged 0-21 years) supported on extracorporeal membrane oxygenation between January, 2017 and December, 2019 compared by palliative care consultation. MEASUREMENTS AND RESULTS: One hundred children (N = 100) were supported with extracorporeal membrane oxygenation; 19% received a palliative care consult. Compared to non-consulted children, consulted children had higher disease severity measured by higher complex chronic conditions at the end of extracorporeal membrane oxygenation hospitalisation (5 versus. 3; p < 0.001), longer hospital length of stay (92 days versus 19 days; p < 0.001), and higher use of life-sustaining therapies after decannulation (79% versus 23%; p < 0.001). Consultations occurred mainly for longitudinal psychosocial-spiritual support after patient survived device deployment with a median of 27 days after cannulation. Most children died in the ICU after withdrawal of life-sustaining therapies regardless of consultation status. Over two-thirds of the 44 deaths (84%; n = 37) occurred during extracorporeal membrane oxygenation hospitalisation. CONCLUSIONS: Palliative care consultation was rare showing that palliative care consultation was not viewed as an acute need and only considered when the clinical course became protracted. As a result, there are missed opportunities to involve palliative care earlier and more frequently in the care of extracorporeal membrane survivors and non-survivors and their families.

Age-based variability in the association between restraint use and injury type and severity in multi-occupant crashes.

PURPOSE: Previous studies have shown older adults receive relatively less protection from seat belts against fatal injuries, however it is unknown how seat belt protection against severe and torso injury changes with age. We estimated age-based variability in seat belt protection against fatal injuries, injuries with maximum abbreviated injury scale greater than two (MAIS 3+), and torso injuries. METHODS: We leveraged the Crash Outcome Data Evaluation System to analyze binary indicators of fatal, MAIS 3+, and torso injuries. Using a matched cohort design and conditional Poisson regression, we estimated age-based relative risks (RR) of the outcomes associated with seat belt use. RESULTS: Our results suggested that seat belts were highly protective against fatal injuries for all ages. For ages 16-30, seat belt use was associated with 66% lower risk of MAIS3+ injury (RR 0.34, 95% CI 0.30, 0.38) for occupants of the same vehicle, whereas for ages 75 and older, seat belt use was associated with 38% lower risk of MAIS3+ injury (RR 0.62; 95% CI 0.45, 0.86) for occupants in the same vehicle. The association between restraint use and torso injury also attenuated with age. CONCLUSIONS: In multi-occupant crashes, seat belts were highly protective against fatal and MAIS3+ injury, however seat belt protection against MAIS3+ and torso injury attenuated with age.
