Pediatric Sepsis in General Emergency Departments: Association Between Pediatric Sepsis Case Volume, Care Quality, and Outcome.

STUDY OBJECTIVE: To assess whether a general emergency department's (ED) annual pediatric sepsis volume increases the odds of delivering care concordant with Surviving Sepsis pediatric guidelines. METHODS: A retrospective cohort study of children <18 years with sepsis presenting to 29 general EDs. Emergency department and hospital data were abstracted from the medical records of 2 large health care systems, including all hospitals to which children were transferred. Guideline-concordant care was defined as intravenous antibiotics within 3 hours, intravenous fluid bolus within 3 hours, and lactate measured. The association between annual ED pediatric sepsis encounters and the probability of receiving guideline-concordant care was assessed. RESULTS: We included 1,527 ED encounters between January 1, 2015, and September 30, 2021. Three hundred and one (19%) occurred in 25 EDs with <10 pediatric sepsis encounters annually, 466 (31%) in 3 EDs with 11 to 100 pediatric sepsis encounters annually, and 760 (50%) in an ED with more than 100 pediatric sepsis encounters annually. Care was concordant in 627 (41.1%) encounters. In multivariable analysis, annual pediatric sepsis volume was minimally associated with the probability of guideline-concordant care (odds ratio 1.002 [95% confidence interval 1.001 to 1.00]). Care concordance increased from 23.1% in 2015 to 52.8% in 2021. CONCLUSION: Guideline-concordant sepsis care was delivered in 41% of pediatric sepsis cases in general EDs, and annual ED pediatric sepsis encounters had minimal association with the odds of concordant care. Care concordance improved over time. This study suggests that factors other than pediatric sepsis volume are important in driving care quality and identifying drivers of improvement is important for children first treated in general EDs.

Preferred language and diagnostic errors in the pediatric emergency department.

OBJECTIVES: To investigate the relationship between language and diagnostic errors (DxE) in the pediatric emergency department (ED). METHODS: Electronic trigger identified ED encounters resulting in unplanned hospital admission that occurred within 10 days of an index visit from January 2018 through February 2022. Manual screening of each triggered encounter identified cases where the index visit diagnosis and hospitalization discharge diagnosis differed, and these were screened in for review using the Revised Safer Dx instrument to determine if a diagnostic error (DxE) occurred. Non-English primary language (NEPL) and English-proficient (EP) groups were established based on caregiver language. The primary outcome was the proportion of DxE each group. Data were analyzed using univariate analysis and multivariable logistic regression to identify independent predictors of DxE. RESULTS: Electronic trigger identified 3,551 patients, of which 806 (22.7 %) screened in for Safer Dx review. 172 (21.3 %) experienced DxE. The proportion of DxE was similar between EP and NEPL groups (21.5 vs. 21.7 %; p=0.97). Age≥12 years and fewer prior admissions in the preceding 6 months predicted higher odds of DxE. NEPL did not predict higher odds of DxE. CONCLUSIONS: NEPL was not associated with increased odds DxE resulting in unplanned admission.

Impact of a discharge prescription for dexamethasone on outcomes of children treated in the emergency department for acute asthma exacerbations.

OBJECTIVE: To evaluate dexamethasone prescribing practices, patient adherence, and outcomes by dosing regimen in children with acute asthma discharged from the emergency department (ED). STUDY DESIGN: Prospective study of children 2-18 years treated with dexamethasone for acute asthma prior to discharge from an urban, tertiary care ED between 2018 and 2022. Demographics, clinical characteristics, ED treatment, and discharge prescriptions were collected via chart review. The exposure was discharge prescription (additional dose) versus no discharge prescription for dexamethasone. The primary outcome was treatment failure, defined as return ED visit, unplanned primary care visit, and/or ongoing bronchodilator use. Secondary outcomes included medication adherence, symptom persistence, quality-of-life, and school/work absenteeism. Outcomes were assessed by telephone 7-10 days after discharge. RESULTS: 564 subjects were enrolled; 338 caregivers (60%) completed follow-up. Children were a median age 7 years, 30% Black or African American, 49% Hispanic, and 79% had public insurance. A discharge prescription for dexamethasone was written for 482 (86%) children and was significantly associated with exacerbation severity, number of combined albuterol/ipratropium treatments, and longer length of stay. There was no difference in treatment failure between the discharge prescription and no discharge prescription groups (RR 0.87; 0.67, 1.12), including after adjusting for potential confounders; there was no difference between groups in secondary outcomes. CONCLUSIONS: Prescription for an additional dexamethasone dose was not associated with reduced treatment failure or improved outcomes for children with acute asthma discharged from the ED. Single, ED-dose of dexamethasone prior to discharge may be sufficient for children with mild to moderate asthma exacerbations.

Toxic Tetrahydrocannabinol (THC) Dose in Pediatric Cannabis Edible Ingestions.

OBJECTIVE: The study characterizes cannabis toxicity in relation to tetrahydrocannabinol (THC) dose in pediatric edible cannabis ingestions. METHODS: This is a retrospective review of children aged <6 years presenting with edible cannabis ingestions of known THC dose within a pediatric hospital network (January 1, 2015-October 25, 2022). Cannabis toxicity was characterized as severe if patients exhibited severe cardiovascular (bradycardia, tachycardia/hypotension requiring vasopressors or intravenous fluids, other dysrhythmias), respiratory (respiratory failure, apnea, requiring oxygen supplementation), or neurologic (seizure, myoclonus, unresponsiveness, responsiveness to painful stimulation only, requiring intubation or sedation) effects. Cannabis toxicity was characterized as prolonged if patients required >6 hours to reach baseline. The relationship between THC dose and severe and prolonged toxicity was explored using multivariable logistic regression and receiver operator characteristic curve analyses. RESULTS: Eighty patients met inclusion. The median age was 2.9 years. The median THC ingestion was 2.1 mg/kg. Severe and prolonged toxicity was present in 46% and 74%, respectively. THC dose was a significant predictor of severe (adjusted odds ratio 2.9, 95% confidence interval: 1.8-4.7) and prolonged toxicity (adjusted odds ratio 3.2, 95% confidence interval: 1.6-6.5), whereas age and sex were not. Area under the curve was 92.9% for severe and 87.3% for prolonged toxicity. THC ingestions of ≥1.7 mg/kg can predict severe (sensitivity 97.3%) and prolonged toxicity (sensitivity 75.4%). CONCLUSIONS: The THC dose of edible cannabis correlates to the degree of toxicity in children <6 years old. The threshold of 1.7 mg/kg of THC may guide medical management and preventive regulations.

Clinical Pathway Adherence and Missed Diagnostic Opportunities Among Children with Musculoskeletal Infections.

INTRODUCTION: Clinical care pathways (CPs) integrate best evidence into the local care delivery context to promote efficiency and patient safety. However, the impact of CPs on diagnostic performance remains poorly understood. The objectives of this study were to evaluate adherence to a musculoskeletal infection (MSKI) diagnostic CP and identify recurrent failure points leading to missed diagnostic opportunities (MDOs). METHODS: Retrospective chart review was performed from January 2018 to February 2022 for children 6 months to 18 years of age who had an unplanned admission for MSKI after being evaluated and discharged from the pediatric emergency department (PED) for related complaints within the previous 10 days. MDOs were identified using the Revised Safer Dx. Demographic and clinical characteristics of children with and without MDOs were compared using bivariate descriptive statistics. An improvement team reviewed the diagnostic trajectories of MDOs for deviations from the MSKI CP and developed a fishbone diagram to describe contributing factors to CP deviations. RESULTS: The study identified 21 children with and 13 children without MSKI-associated MDOs. Children with MDOs were more likely to have an initial C-reactive protein value > 2 mg/dL (90.0% vs. 0%, p = 0.01) and returned to care earlier than children without MDOs (median 2.8 days vs. 6.7 days, p = 0.004). Factors contributing to MDOs included failure to obtain screening laboratory tests, misinterpretation of laboratory values, failure to obtain orthopedic consultation, and failure to obtain definitive imaging. CONCLUSION: Several recurrent deviations from an MSKI diagnostic CP were found to be associated with MDOs. Future quality improvement efforts to improve adherence to this MSKI CP may prevent MDOs.

Impact of Adjunct Corticosteroid Therapy on Quality of Life for Children With Suspected Pneumonia.

OBJECTIVE: To determine the association between adjunct corticosteroid therapy and quality of life (QoL) outcomes in children with signs and symptoms of lower respiratory tract infection and clinical suspicion for community-acquired pneumonia (CAP) in the emergency department (ED). METHODS: Secondary analysis from a prospective cohort study of children aged 3 months to 18 years with signs and symptoms of LRTI and a chest radiograph for suspected CAP in the ED, excluding children with recent (within 14 days) systemic corticosteroid use. The primary exposure was receipt of corticosteroids during the ED visit. Outcomes were QoL measures and unplanned visits. Multivariable regression was used to evaluate the association between corticosteroid therapy and outcomes. RESULTS: Of 898 children, 162 (18%) received corticosteroids. Children who received corticosteroids were more frequently boys (62%), Black (45%), had history of asthma (58%), previous pneumonia (16%), presence of wheeze (74%), and more severe illness at presentation (6%). Ninety-six percent were treated for asthma as defined by report of asthma or receipt of ß-agonist in the ED. Receipt of corticosteroids was not associated with QoL measures: days of activity missed (adjusted incident rate ratio [aIRR], 0.84; 95% confidence interval [CI], 0.63-1.11) and days of work missed (aIRR, 0.88; 95% CI, 0.60-1.27). There was a statistically significant interaction between age (>2 years) and corticosteroids receipt; the patients had fewer days of activity missed (aIRR, 0.62; 95% CI, 0.46-0.83), with no effect on children 2 years or younger (aIRR, 0.83; 95% CI, 0.54-1.27). Corticosteroid treatment was not associated with unplanned visit (odds ratio, 1.37; 95% CI, 0.69-2.75). CONCLUSIONS: In this cohort of children with suspected CAP, receipt of corticosteroids was associated with asthma history and was not associated with missed days of activity or work, except in a subset of children aged older than 2 years.

Long-term physical and mental health outcomes of pediatric firearm-injured victims: A prospective cohort study.

BACKGROUND: Firearms are a leading cause of injury among US youth. There is little research describing outcomes after pediatric firearm injuries, particularly past 1 year. OBJECTIVE: This study aimed to assess long-term physical and mental health outcomes among nonfatal firearm versus motor vehicle collision (MVC)-injured victims and versus a standard population. METHODS: We retrospectively identified firearm and MVC-injured pediatric patients seen at one of our four trauma centers (January 2008 to October 2020) and prospectively assessed outcomes using validated patient-reported outcome measures. Eligible patients were English speaking, injured ≥5 months before study start, younger than 18 years at time of injury, and 8 years or older at study start. All firearm patients were included; MVC patients were matched 1:1 with firearm patients for Injury Severity Score (dichotomized <15 or ≥15), age range (±1 year), and year of injury. We conducted structured interviews of patients and parents using validated tools (Patient-Reported Outcomes Measurement Information System tools, Children's Impact of Event Scale for younger than 18 years and parent proxies). Patient-Reported Outcomes Measurement Information System scores are reported on a T score metric (mean [SD], 50 [10]); higher scores indicate more of the measured domain. We used paired t tests, Wilcoxon signed-rank tests, and McNemar's test to compare demographics, clinical characteristics, and outcomes. RESULTS: There were 24 participants in each of the MVC and firearm-injured groups. Compared with MVC-injured patients, firearm-injured patients younger than 18 years had similar scores, and firearm-injured patients 18 years or older had higher anxiety scores (59.4 [8.3] vs. 51.2 [9.4]). Compared with a standard population, patients younger than 18 years had worse global health scores (mean [SD], 43.4 [9.7]), and participants 18 years or older reported increased fatigue (mean [SD], 61.1 [3.3]) and anxiety (mean [SD], 59.4 [8.3]). CONCLUSION: Long-term effects of firearm-injured patients were poorer than matched MVC and the standard population in few domains. Further study in a larger, prospectively recruited cohort is warranted to better characterize physical and mental health outcomes.

Acceptability of Long Versus Short Firearm Safety Education Videos in the Emergency Department: A Pilot Randomized Controlled Trial.

STUDY OBJECTIVE: Safe firearm storage is protective against pediatric firearm injuries. We sought to compare a 3-minute versus 30-second safe firearm storage video in terms of acceptability of video content and use in the pediatric emergency department (PED). METHODS: We conducted a randomized controlled trial in a large PED (from March to September 2021). Participants were English-speaking caregivers of noncritically ill patients. Participants were surveyed about child safety behaviors (including firearm storage), then shown 1 of 2 videos. Both videos described safe storage principles; the 3-minute video included temporary firearm removal and a survivor testimonial. The primary outcome was acceptability, measured by responses on a 5-point Likert scale (strongly disagree to strongly agree). A survey at 3 months evaluated information recall. Baseline characteristics and outcomes were compared between groups using Pearson chi-squared, Fisher exact, and Wilcoxon Mann Whitney tests as appropriate. Absolute risk difference for categoric variables and mean difference for continuous variables are reported with 95% confidence interval (CI). RESULTS: Research staff screened 728 caregivers; 705 were eligible and 254 consented to participate (36%); 4 withdrew. Of 250 participants, most indicated acceptability in terms of setting (77.4%) and content (86.6%), and doctors discussing firearm storage (78.6%), with no difference between groups. More caregivers viewing the longer video felt the length appropriate (99.2%) compared with the shorter video (81.1%, difference 18.1%, 95% CI 11.1 to 25.1). CONCLUSIONS: We show that video-based firearm safety education is acceptable among study participants. This can provide consistent education to caregivers in PEDs and needs further study in other settings.

Parental perspective on penicillin allergy delabeling in a pediatric emergency department.

BACKGROUND: Penicillin (PCN) allergy is frequently mislabeled and inaccurately diagnosed in children. Successful implementation of pediatric emergency department (PED) delabeling efforts requires parental understanding and willingness for children to be delabeled as PCN-nonallergic. OBJECTIVE: To describe the parental perspective on allergy delabeling in the PED for children identified as low risk for true PCN allergy. METHODS: This is a cross-sectional survey of parents of children with documented PCN allergy presenting to a single tertiary-care PED. Parents were first approached to complete a PCN allergy identification questionnaire to stratify their child as high- or low-risk for true PCN allergy. Facilitators and barriers to PED-based oral challenge and delabeling were subsequently assessed by parents of low-risk children. RESULTS: A total of 198 participants completed the PCN identification questionnaire. Of 198 children, 49 (25%) screened low risk for true PCN allergy. Of the 49 low-risk children, 29 (59%) parents were uncomfortable with a PED-based PCN oral challenge. Reasons include fear of allergic reaction (72%), availability of adequate alternative antibiotics (45%), and longer PED stay (17%). Reasons for willingness to delabel included PCN's low adverse effect profile (65%) and avoidance of antimicrobial resistance from alternative antibiotics (74%). Participants without a family history (FH) of PCN allergy were more comfortable with PED-based PCN oral challenge (60% vs 11%; P = .001) and delabeling (67% vs 37%; P = .04) compared with those with FH. CONCLUSION: Most parents of children with low-risk PCN allergy are uncomfortable with oral challenge or delabeling in the PED. Before implementing oral challenges in PEDs, efforts should be made to highlight the safety of oral challenging low-risk children, the benefits and risks of alternative antibiotics, and the minimal impact that FH has on PCN allergy.

Variation in diagnosis and management of allergic reactions among emergency medicine and allergy immunology providers.

Background: Children with anaphylaxis often emergently present for treatment. Providers' adherence to the principles of optimal management according to the most recent national guidelines is unknown. Objective: To assess the variation in management approaches for allergic reactions and anaphylaxis between allergy/immunology (AI) and emergency medicine (EM) providers. Methods: This was a cross-sectional survey study of AI and EM providers in the University of Colorado affiliated hospitals and Colorado Asthma and Allergy Society. The survey consisted of six cases of patients with allergic reactions, with four cases that represented patients with anaphylaxis that resolved by the time of discharge. For each vignette, the participants were asked about preferred initial therapy, adjunctive therapies, monitoring, outpatient prescription medications, and discharge instructions provided. Survey derivation and validation was accomplished by a multidisciplinary team of experts by using a modified Delphi process. Results: A total of 413 clinicians were contacted, of whom 194, (47%) responded, including 69 pediatric EM, 50 general EM, and 49 AI providers, and 26 did not identify a provider type. There were no statistically significant differences in correct recognition of anaphylaxis between the AI and EM providers. For each case, statistically significant differences were noted in the use of corticosteroids during and after resolution of anaphylaxis: AI providers reported giving fewer prescriptions than did the EM providers for corticosteroids in all cases of anaphylaxis (p < 0.001). The AI providers were less likely to prescribe scheduled antihistamines than were the EM providers in half of the cases (p < 0.02). Conclusion: Across the specialties, there were high rates of recognition of epinephrine as first-line treatment for anaphylaxis. The majority of the EM providers prescribed scheduled corticosteroids and antihistamines after resolution of anaphylaxis, whereas most of the AI providers did not prescribe scheduled corticosteroids. Analysis of the current data suggests against the routine use of corticosteroids in the management of anaphylaxis, particularly continued use after resolution of symptoms. AI involvement in the creation of EM and hospital protocols for allergic reactions could improve overall care.

Comparison of Two-Bag Versus Three-Bag N-Acetylcysteine Regimens for Pediatric Acetaminophen Toxicity.

BACKGROUND: Acetaminophen overdose is a leading cause of liver failure, and a leading cause of pediatric poisoning requiring hospital admission. The antidote, N-acetylcysteine (NAC), is traditionally administered as a three-bag intravenous infusion. Despite its efficacy, NAC is associated with high incidence of nonallergic anaphylactoid reactions (NAARs). Adult evidence demonstrates that alternative dosing regimens decrease NAARs and medication errors (MEs). OBJECTIVES: To compare NAARs and MEs associated with two- versus three-bag NAC for acetaminophen overdose in a pediatric population. METHODS: This is a retrospective observational cohort study comparing pediatric patients who received three- versus two-bag NAC for acetaminophen toxicity. The primary outcome was incidence of NAARs. Secondary outcomes were rates of MEs and relevant hospital outcomes (length of stay [LOS], intensive care unit (ICU) admission, liver transplant, death). RESULTS: Two hundred forty-three patients met inclusion criteria (median age of 15 years): 150 (62%) three-bag NAC and 93 (38%) two-bag NAC. There was no difference in overall NAARs (p = 0.54). Fewer cutaneous NAARs were observed in the two-bag group, three-bag: 15 (10%), two-bag: 2 (2%), p = 0.02. MEs were significantly decreased with the two-bag regimen, three-bag: 59 (39%), two-bag: 21 (23%), p = 0.01. No statistical differences were observed in LOS, ICU admissions, transplant, or death. CONCLUSION AND RELEVANCE: A significant decrease in cutaneous NAARs and MEs was observed in pediatric patients by combining the first two bags of the traditional three-bag NAC regimen. In pediatric populations, a two-bag NAC regimen for acetaminophen overdose may improve medication tolerance and safety.

Incidence of postoperative seizures in neonates following cardiac surgery with regional cerebral perfusion and deep hypothermic circulatory arrest.

Objectives: Historically, our center has primarily used deep hypothermic circulatory arrest, but in recent years some surgeons have selectively used regional cerebral perfusion as an alternative. We aimed to compare the incidence of postoperative electroencephalographic seizure incidence in neonates undergoing surgery with regional cerebral perfusion and deep hypothermic circulatory arrest. Methods: A retrospective analysis was performed in neonates who underwent surgery between 2012 and 2022 with either deep hypothermic circulatory arrest or regional cerebral perfusion with routine postoperative continuous electroencephalography monitoring for 48 hours. Propensity matching was performed to compare postoperative seizure risk between the 2 groups. Results: Among 1136 neonates undergoing cardiac surgery with cardiopulmonary bypass, regional cerebral perfusion was performed in 99 (8.7%) and deep hypothermic circulatory arrest in 604 (53%). The median duration of regional cerebral perfusion was 49 minutes (interquartile range, 38-68) and deep hypothermic circulatory arrest was 41 minutes (interquartile range, 31-49). The regional cerebral perfusion group had significantly longer total support, cardiopulmonary bypass, and aortic crossclamp times. Overall seizure incidence was 11% (N = 76) and 13% (N = 35) in the most recent era (2019-2022). The unadjusted seizure incidence was similar in neonates undergoing regional cerebral perfusion (N = 12, 12%) and deep hypothermic circulatory arrest (N = 64, 11%). After propensity matching, the seizure incidence was similar in neonates undergoing regional cerebral perfusion (N = 12, 12%) and deep hypothermic circulatory arrest (N = 37, 12%) (odds ratio, 0.97; 95% CI, 0.55-1.71; P = .92). Conclusions: In this contemporary single-center experience, the incorporation of regional cerebral perfusion did not result in a change in seizure incidence in comparison with deep hypothermic circulatory arrest. However, unmeasured confounders may have impacted these findings. Further studies are needed to determine the impact, if any, of regional cerebral perfusion on postoperative seizure incidence.

Adolescent US Poison Center Exposure Calls During the COVID-19 Pandemic.

PURPOSE: The objective of this study was to evaluate trends and characteristics in adolescent poison center (PC) exposure calls before and during the COVID-19 pandemic. METHODS: A retrospective review of PC calls for adolescents aged 13-17 years from January 1, 2018 through June 30, 2021. RESULTS: During the pandemic, US PCs had a higher proportion of adolescent exposure calls managed in a healthcare facility (71.9% vs. 67.4%) and hospital admissions (27.2% vs. 25.7%) than prior to the pandemic. There was a higher proportion with suicide intent (55.8% vs. 48.8%), moderate/major clinical effects (22.8% vs. 20.1%), and deaths (0.07% vs. 0.05%). Monthly calls significantly increased from 30 calls/month to 204 calls/month (p < .001). The slope of hospital admissions significantly increased (0.19% per month, p < .001) during the pandemic. DISCUSSION: During the COVID-19 pandemic, US PCs observed an increase in adolescent suicidal intent exposure calls with more severe outcomes, hospitalizations, and deaths.

Individual and neighborhood level characteristics of pediatric firearm injuries presenting at trauma centers in Colorado.

BACKGROUND: Firearm injuries are the second leading cause of death among children and adolescents in the United States. In Colorado, firearm injuries have surpassed motor vehicle accidents as the leading cause of death in youth. Local research is necessary to characterize risk factors associated with pediatric firearm injuries. We sought to categorize demographics, neighborhood characteristics, and trends in pediatric firearm injuries in Colorado. METHODS: A review of pediatric firearm-injured patients (18 years or younger) evaluated at four trauma centers in Colorado from 2008 to 2019 was conducted. Clinical information, injury intent, and demographics were collected. Patient addresses were geocoded to census tracts to obtain neighborhood-level characteristics. Annual trends in firearm injury incidence per trauma evaluation were analyzed using regression modeling. RESULTS: There were 446 firearm injuries during the study period. The median age was 16 years, and 87.0% were male. Assault was the most common injury intent (64.6%), and 92.0% of patients were from metropolitan (rural-urban continuum code 1-3) areas. Neighborhoods associated with firearm injuries were characterized by lower median household income ($47,112 vs. $63,443, p < 0.001) and higher levels of poverty (19.1% vs. 9.4%, p < 0.001) compared with median state levels. There was a 14.0% increase in firearm injuries compared with overall trauma evaluations for each year in the study period (incidence rate ratio, 1.14; 95% confidence interval, 1.08-1.20; p < 0.001). CONCLUSION: The incidence of pediatric firearm injuries increased significantly from 2008 to 2019 compared with overall trauma evaluations in Colorado. Children and adolescents who live in more socially vulnerable neighborhoods are disproportionately impacted, and injury prevention resources should be focused on these communities. LEVEL OF EVIDENCE: Prognostic and Epidemiolgic; Level III.

Neuroimaging for Pediatric Non-First-Time Seizures in the Emergency Department.

Background and Objectives: Neuroimaging is often part of the workup for a pediatric patient presenting with a seizure to an emergency department (ED). We aim to evaluate when neuroimaging in the ED for children with a non-first-time seizure, or nonindex seizure (NIS), is associated with an acute change in management (ACM). Methods: This is a retrospective cohort study of all pediatric patients presenting to an ED from 2008 to 2018 with a NIS, excluding repeat febrile seizures, who underwent neuroimaging. Clinical characteristics were extracted from the electronic medical record. The primary outcome was new abnormal neuroimaging resulting in an ACM, defined as admission to the hospital, neurosurgical intervention, or new nonseizure medication administration. Results: We identified 492 encounters. Neuroimaging revealed new findings in 21% of encounters and led to ACMs in 5% of encounters. ACMs included admissions, neurosurgical interventions, and nonseizure medication changes. Factors associated with ACM included new seizure type (odds ratio [OR] 3.3, 95% confidence interval [CI] 1.3-8.0), new focal examination finding (OR 3.0, 95% CI 1.3-7.1), altered mental status (OR 2.9, 95% CI 1.2-7.0), and a history of only provoked seizures (OR 2.8, 95% CI 1.0-7.5). Patients with 2 risk factors had an OR of 6.9 (95% CI 1.8-26.5) for an ACM, and those with 3-4 risk factors had an OR of 45.8 (95% CI 9.8-213.2). The negative predictive value for ACM in a patient with no risk factors was 98.6% (95% CI 95.9-99.5). Discussion: Patients with a NIS who have abnormal neuroimaging associated with an ACM present with unique risk factors. Prospectively validating these factors may allow for a prediction tool for NIS in EDs where reduced exposure to ionizing radiation, sedation, and resource utilization are critically important.

Evaluating Provider Documentation of Suicide Risk Factors Among Youth Screening Positive for Suicide Risk in a Pediatric Emergency Department.

OBJECTIVE: Screening for suicidal ideation in the pediatric emergency department (ED) enhances recognition of suicidality among patients presenting with a nonmental health complaint. Little is known about the assessment of suicide risk factors and disposition among these patients. This study aimed to evaluate pediatric ED providers' documentation of suicide risk factors in this population. METHODS: We performed a retrospective cohort study of patients screening at risk for suicide on the Ask Suicide-Screening Questions tool. Demographic variables and risk factors for youth suicide were extracted from the electronic health record for eligible patients each month from January 1, 2019, to December 31, 2019. We compared risk factors using χ2 or Fisher exact test. RESULTS: In 2019, of the 7484 patients screened for suicide, 524 (7%) had a positive screen. Of 220 patient charts reviewed, no suicide risk factors were documented in 53.6% of encounters, and only 1 risk factor was documented in 18.2% of encounters. Substance use was the most frequently discussed risk factor, documented in 33.6% of encounters. History of nonsuicidal self-injury was documented in 11.8% of visits. Other risk factors were documented in fewer than 10% of at-risk patients. CONCLUSION: Pediatric ED providers do not routinely document risk factors for suicide in medical patients screening at risk. Although the Ask Suicide-Screening Questions is an important initial screen, a standardized secondary risk factor assessment is necessary for a more complete risk stratification for patients with suicidal ideation.

Use of e-triggers to identify diagnostic errors in the paediatric ED.

BACKGROUND: Diagnostic errors (DxEs) are an understudied source of patient harm in children rarely captured in current adverse event reporting systems. Applying electronic triggers (e-triggers) to electronic health records shows promise in identifying DxEs but has not been used in the emergency department (ED) setting. OBJECTIVES: To assess the performance of an e-trigger and subsequent manual screening for identifying probable DxEs among children with unplanned admission following a prior ED visit and to compare performance to existing incident reporting systems. DESIGN/METHODS: Retrospective single-centre cohort study of children ages 0-22 admitted within 14 days of a previous ED visit between 1 January 2018 and 31 December 2019. Subjects were identified by e-trigger, screened to identify cases where index visit and hospital discharge diagnoses were potentially related but pathophysiologically distinct, and then these screened-in cases were reviewed for DxE using the SaferDx Instrument. Cases of DxE identified by e-trigger were cross-referenced against existing institutional incident reporting systems. RESULTS: An e-trigger identified 1915 unplanned admissions (7.7% of 24 849 total admissions) with a preceding index visit. 453 (23.7%) were screened in and underwent review using SaferDx. 92 cases were classified as likely DxEs, representing 0.4% of all hospital admissions, 4.8% among those selected by e-trigger and 20.3% among those screened in for review. Half of cases were reviewed by two reviewers using SaferDx with substantial inter-rater reliability (Cohen's κ=0.65 (95% CI 0.54 to 0.75)). Six (6.5%) cases had been reported elsewhere: two to the hospital's incident reporting system and five to the ED case review team (one reported to both). CONCLUSION: An e-trigger coupled with manual screening enriched a cohort of patients at risk for DxEs. Fewer than 10% of DxEs were identified through existing surveillance systems, suggesting that they miss a large proportion of DxEs. Further study is required to identify specific clinical presentations at risk of DxEs.

Facilitators and barriers for parental consent to pediatric emergency research.

BACKGROUND: Obtaining informed consent for clinical research in the pediatric emergency department (ED) is challenging. Our objective was to understand the factors that influence parental consent for ED studies. METHODS: This was a cross-sectional survey assessing parents' willingness to enroll their children into an ED research study. Parents reporting a willingness to enroll in ED studies were presented with two hypothetical scenarios, a low-risk and a high-risk study, and then asked about decision influencers affecting consent. Parents expressing a lack of willingness to enroll were asked which decision influencers impacted their consent decision. RESULTS: Among 118 parents, 90 (76%) stated they would be willing to enroll their child into an ED study; of these, 86 (96%) would consent for a low-risk study and 54 (60%) would consent for a high-risk study. Caucasian parents, and those with previous research exposure, were more likely to report willingness to participate. Those who would consent to the high-risk study cited "benefits that research would provide to future children" most strongly influenced their decision to agree. CONCLUSIONS: ED investigators should highlight the benefits for future children and inquire about parents' previous exposure to research to enhance ED research enrollment. Barriers to consent in non-Caucasian families should be further investigated. IMPACT: Obtaining consent for pediatric emergency research is challenging and this study identified factors influencing parental consent for research in EDs. Benefits for future children and parents' previous research experience were two of the most influential factors in parents' willingness to consent to ED research studies. These findings will help to improve enrollment in ED research studies and better our understanding of how to promote the health and well-being of pediatric patients.

Diagnostic Accuracy of Suspected Appendicitis: A Comparative Analysis of Misdiagnosed Appendicitis in Children.

OBJECTIVE: When evaluating suspected appendicitis, limited data support quality benchmarks for negative appendectomy (NA); none exist for delayed diagnosis of appendicitis (DDA). The objectives of this study are the following: (1) to provide preliminary evidence supporting a quality benchmark for DDA and 2) to compare presenting features and diagnostic evaluations of children with NA and DDA with those with pathology-confirmed appendicitis (PCA) diagnosed during initial emergency department (ED) encounter. METHODS: Secondary analysis of data from a QI project designed to reduce the use computed tomography when evaluating suspected appendicitis using a case-control design. Patients undergoing appendectomy in an academic tertiary care children's hospital system between January 1, 2015, and December 31, 2016 (n = 1,189) were eligible for inclusion in this case-control study. Negative appendectomy was defined as no pathologic change or findings consistent with a different diagnosis. Delayed diagnosis of appendicitis was defined as patients undergoing appendectomy within 7 days of a prior ED visit for a related complaint. Controls of PCA (n = 150) were randomly selected from all cases undergoing appendectomy. RESULTS: There were 42 NA (3.5%) and 31 DDA (2.6%). Cases of PCA and NA exhibited similar histories, examination findings, and underwent comparable diagnostic evaluations. Cases of PCA more frequently demonstrated a white blood cell count greater than 10 × 103/µL (85% vs 67%; P = 0.01), a left-shift (77% vs 45%; P < 0.001), and an ultrasound interpretation with high probability for appendicitis (73% vs 54%; P = 0.03). Numerous significant differences in history, examination findings, and diagnostic tests performed existed between cases of PCA and DDA. CONCLUSIONS: Children with PCA and NA present similarly and undergo comparable evaluations resulting in appendectomy. A 3% to 4% NA rate may be unavoidable given these similarities. Presenting features in DDA significantly differ from those of PCA. An irreducible proportion of appendicitis diagnoses may be delayed.

Trends of prescription psychotropic medication exposures in pediatric patients, 2009-2018.

BACKGROUND: Mental health disorders and related suicide attempts are increasing in both the adult and pediatric patient populations. Because of the increasing prevalence of mental health disorders, there is increased use of psychotropic medications in adult and pediatric patients, which can pose a risk for potentially adverse pediatric ingestions. The objective was to determine trends and outcomes for pediatric psychotropic medication ingestions reported to the American Association of Poison Control Centers (AAPCC) National Poison Data System (NPDS). METHODS: This was a retrospective review of pediatric (≤18 years of age) exposures reported to AAPCC NPDS between January 1, 2009 and December 31, 2018. Single psychotropic medication ingestions of atypical antipsychotics, bupropion, buspirone, clonidine, lithium, methylphenidate, mirtazapine, monoamine oxidase inhibitors (MAOIs), selective norepinephrine reuptake inhibitors (SNRIs), selective serotonin reuptake inhibitors (SSRIs), trazodone, and tricyclic antidepressants (TCAs) were examined. RESULTS: Over the 10-year study period, 356,548 pediatric psychotropic medication ingestions were reported to NPDS. SSRI ingestions were the most frequently reported (34%), followed by atypical antipsychotics (17%), and methylphenidate (15%). Unintentional ingestions were most prominent in patients 0-12 years of age (79%), whereas, in patients age 13-18 years, 76% were intentional. SSRI ingestions were asymptomatic in 68% of cases. Clonidine and bupropion ingestions had the highest proportion of moderate and major clinical effects (29 and 25%, respectively). There were 29 deaths: atypical antipsychotics (n = 4), bupropion (n = 10), lithium (n = 1), SNRI (n = 1), SSRIs (n = 7), and TCAs (n = 6); 19 (65%) were in adolescent patients. CONCLUSIONS: SSRIs were the most frequently reported ingestion, while bupropion and clonidine were associated with a high percentage of moderate and major clinical effects. This study demonstrates opportunities for targeted prevention strategies to prevent potentially adverse pediatric ingestions to psychotropic medications.
