24-Hour warning signs for adolescent suicide attempts.

BACKGROUND: Little is known about when youth may be at greatest risk for attempting suicide, which is critically important information for the parents, caregivers, and professionals who care for youth at risk. This study used adolescent and parent reports, and a case-crossover, within-subject design to identify 24-hour warning signs (WS) for suicide attempts. METHODS: Adolescents (N = 1094, ages 13 to 18) with one or more suicide risk factors were enrolled and invited to complete bi-weekly, 8-10 item text message surveys for 18 months. Adolescents who reported a suicide attempt (survey item) were invited to participate in an interview regarding their thoughts, feelings/emotions, and behaviors/events during the 24-hours prior to their attempt (case period) and a prior 24-hour period (control period). Their parents participated in an interview regarding the adolescents' behaviors/events during these same periods. Adolescent or adolescent and parent interviews were completed for 105 adolescents (81.9% female; 66.7% White, 19.0% Black, 14.3% other). RESULTS: Both parent and adolescent reports of suicidal communications and withdrawal from social and other activities differentiated case and control periods. Adolescent reports also identified feelings (self-hate, emotional pain, rush of feelings, lower levels of rage toward others), cognitions (suicidal rumination, perceived burdensomeness, anger/hostility), and serious conflict with parents as WS in multi-variable models. CONCLUSIONS: This study identified 24-hour WS in the domains of cognitions, feelings, and behaviors/events, providing an evidence base for the dissemination of information about signs of proximal risk for adolescent suicide attempts.

A Prospective Examination of the Interpersonal-Psychological Theory of Suicidal Behavior in Adolescents.

OBJECTIVE: Given the large and complex array of suicide risk factors, theoretical frameworks are critical to furthering our understanding of risk. This study prospectively examined several key constructs of the interpersonal-psychological theory of suicidal behavior (IPTS) in a large, geographically diverse sample of U.S. adolescents. METHOD: Conducted in collaboration with the Pediatric Emergency Care Applied Research Network, adolescents, ages 12 to 17, were recruited from emergency departments. Baseline and 6-month follow-up samples were comprised of 6,448 (59% female sex) and 2,009 (64% female sex) adolescents, with self-identified race/ethnicity as follows (baseline/follow-up): White (52%/54%), Black (22%/23%), Multiracial (6%/6%), American Indian (3%/3%), other/unknown race (15%/14%), and Latinx (25%/23%). Youth and parents completed adolescent suicide risk surveys at baseline and 6-month follow-up (retention, 69%). Latent class analysis was used to identify classes of painful and provocative events (PPE), considered a precursor to acquired capability. RESULTS: In keeping with IPTS tenets, thwarted belongingness (TB), perceived burdensomeness (PB), and the interaction between TB and PB were each significant predictors of suicidal ideation at baseline and follow-up. However, only PB and PPE were significant predictors of cross-sectional suicide attempts and only TB and PPE were significant predictors of prospective suicide attempts in models that adjusted for baseline suicidal ideation. The three-way interaction among PB, TB and PPE was nonsignificant. CONCLUSIONS: Results from this large-scale prospective study suggest the importance of TB, PB, and PPE to our understanding of suicidal thoughts and suicide attempts among adolescents, pointing to promising prevention and intervention targets.

Implementation of a Suicide Risk Screening Clinical Pathway in a Children's Hospital: A Feasibility Study.

OBJECTIVES: Youth suicide is a pressing global concern. Prior research has developed evidence-driven clinical pathways to screen and identify suicide risk among pediatric patients in outpatient clinics, emergency departments (ED) and inpatient hospital units. However, the feasibility of implementing these pathways remains to be established. Here, we share the results of a hospital-wide "youth suicide risk screening pathway" implementation trial at an urban academic pediatric hospital to address this gap. METHODS: A 3-tier "youth suicide risk screening pathway" using The Ask Suicide-Screening Questions (ASQ) was implemented for patients aged 10 to 26 years who received care at an urban academic pediatric hospital's emergency department or inpatient units. We retrospectively reviewed implementation outcomes of this pathway from January 1 to August 31, 2019. The feasibility of this implementation was measured by assessing the pathway's degree of execution, fidelity, resource utilization, and acceptability. RESULTS: Of 4108 eligible patient encounters, 3424 (83%) completed the screen. Forty-eight (1%) screened acute positive, 263 (8%) screened nonacute positive and 3113 (91%) screened negative. Patients reporting positive suicide risk were more likely to be older and female, although more males required specialty mental health evaluations. Pathway fidelity was 83% among all positive screens and 94% among acute positive screens. The clinical pathway implementation required 16 hours of provider training time and was associated with slightly longer length of stay for inpatients that screened positive (4 vs 3 days). Sixty-five percent of nurses and 78% of social work providers surveyed supported participation in this effort. CONCLUSIONS: It is feasible to implement a youth suicide risk screening pathway without overburdening the system at an urban academic pediatric hospital.

Social connectedness and adolescent suicide risk.

BACKGROUND: Despite evidence of the importance of interpersonal connectedness to our understanding of suicide risk, relatively little research has examined the protective and buffering effects of connectedness among adolescents. The aims of this study were to determine: (a) whether overall connectedness (composite of family, peer, and school) and specific domains of connectedness were related to a lower likelihood of suicide attempts, and (b) whether these factors buffer the prospective risk of suicide attempt for high-risk subgroups (i.e., recent suicidal ideation and/or lifetime history of suicide attempt, peer victimization, or sexual and gender minority status). METHODS: Participants were 2,897 adolescents (64.7% biological female), ages 12 to 17 (M = 14.6, SD = 1.6), recruited in collaboration with the Pediatric Emergency Care Applied Research Network (PECARN) from 14 emergency departments for the Emergency Department Screen for Teens at Risk for Suicide Study (ED-STARS). Suicide risk and protective factors were assessed at baseline; 3- and 6-month follow-ups were completed (79.5% retention). Multivariable logistic regressions were conducted, adjusting for established suicide risk factors. RESULTS: Higher overall connectedness and, specifically, school connectedness were associated with decreased likelihood of a suicide attempt across 6 months. Overall connectedness and connectedness domains did not function as buffers for future suicide attempts among certain high-risk subgroups. The protective effect of overall connectedness was lower for youth with recent suicidal ideation or a suicide attempt history than for those without this history. Similarly, overall connectedness was protective for youth without peer victimization but not those with this history. Regarding specific domains, family connectedness was protective for youth without recent suicidal ideation or a suicide attempt history and peer connectedness was protective for youth without peer victimization but not youth with these histories. CONCLUSIONS: In this large and geographically diverse sample, overall and school connectedness were related prospectively to lower likelihood of suicide attempts, and connectedness was more protective for youth not in certain high-risk subgroups. Results inform preventive efforts aimed at improving youth connectedness and reducing suicide risk.

Toxic Exposures Among Young Children One Year into the COVID-19 Pandemic: A Retrospective Review of Three San Francisco Bay Area Emergency Departments.

BACKGROUND: Daycare and school closures prompted by shelter-in-place orders may have increased opportunities for unintentional ingestions among young children. OBJECTIVES: We examined emergency department (ED) presentations for toxic exposures among young children during the COVID-19 pandemic in the San Francisco Bay Area, which had some of the strictest and most prolonged shelter-in-place policies in the United States. METHODS: We performed a retrospective cross-sectional study of children 0 to 5 years of age who presented with an ED International Statistical Classification of Diseases and Related Health Problems, Tenth Revision diagnosis code of toxic exposure within a tertiary care hospital system between March 16, 2016 and March 15, 2021. We considered the period after March 16, 2020 to represent the pandemic. RESULTS: During the pandemic, the absolute number of poisonings among young children remained stable. Overall, ED encounters within this cohort decreased by 55%, which doubled the relative toxic exposure rate per 1000 ED encounters from 4.99 (95% confidence interval [CI] 3.19-5.90) to 9.79 (95% CI 8.09-11.49). Rates of admission, severe medical complications, operating room case requests, and length of stay were not significantly different. Shelter-in-place was associated with significantly higher odds of cannabis ingestion (odds ratio = 2.70, 95% CI 1.60-4.49). CONCLUSION: Despite dramatic decreases in overall ED patient volumes, the absolute number and severity of toxic exposures were similar during the pandemic compared with previous years. © 2022 Elsevier Inc.

Understanding adolescent responses to differently worded suicide attempt questions: results from a large US pediatric sample.

BACKGROUND: Clinical assessments are a primary method for ascertaining suicide risk, yet the language used across measures is inconsistent. The implications of these discrepancies for adolescent responding are unknown, which is troubling as multiple research areas (i.e. on culture, mental health language, and suicide communication) indicate individuals from varying sociodemographic backgrounds may communicate differently regarding mental health concerns. The aims of the current study are to investigate whether a geographically diverse sample of adolescents respond differently to directly and indirectly phrased suicide attempt questions (i.e. directly phrased includes the term 'suicide' and indirectly asks about suicidal behavior without using 'suicide'), and to examine whether sociodemographic factors and history of mental health service usage relate to endorsement differences. METHODS: Participants were N = 5909 adolescents drawn from the Emergency Department Screening for Teens at Risk for Suicide multi-site study. The lifetime suicide attempt was assessed with two items from an adapted version of the Columbia Suicide Severity Rating Scale (C-SSRS; Posner et al., 2008): (1) a directly phrased question asking about 'suicide attempts' and (2) an indirectly phrased question providing the definition of an attempt. RESULTS: An adolescent majority (83.7%) consistently reported no lifetime suicide attempt across items, 10.1% consistently reported one or more lifetime attempts across items, and 6.2% of adolescents responded discordantly to the items. CONCLUSIONS: Multivariable models indicated multiple demographic and mental health service variables significantly predicted discordant responding, with a notable finding being that father/stepfather education level at or below high school education predicted endorsing only the direct question.

Development and Validation of a Deep Learning Strategy for Automated View Classification of Pediatric Focused Assessment With Sonography for Trauma.

OBJECTIVE: Pediatric focused assessment with sonography for trauma (FAST) is a sequence of ultrasound views rapidly performed by clinicians to diagnose hemorrhage. A technical limitation of FAST is the lack of expertise to consistently acquire all required views. We sought to develop an accurate deep learning view classifier using a large heterogeneous dataset of clinician-performed pediatric FAST. METHODS: We developed and conducted a retrospective cohort analysis of a deep learning view classifier on real-world FAST studies performed on injured children less than 18 years old in two pediatric emergency departments by 30 different clinicians. FAST was randomly distributed to training, validation, and test datasets, 70:20:10; each child was represented in only one dataset. The primary outcome was view classifier accuracy for video clips and still frames. RESULTS: There were 699 FAST studies, representing 4925 video clips and 1,062,612 still frames, performed by 30 different clinicians. The overall classification accuracy was 97.8% (95% confidence interval [CI]: 96.0-99.0) for video clips and 93.4% (95% CI: 93.3-93.6) for still frames. Per view still frames were classified with an accuracy: 96.0% (95% CI: 95.9-96.1) cardiac, 99.8% (95% CI: 99.8-99.8) pleural, 95.2% (95% CI: 95.0-95.3) abdominal upper quadrants, and 95.9% (95% CI: 95.8-96.0) suprapubic. CONCLUSION: A deep learning classifier can accurately predict pediatric FAST views. Accurate view classification is important for quality assurance and feasibility of a multi-stage deep learning FAST model to enhance the evaluation of injured children.

Trends in Use of Diagnostic Imaging for Abdominal Pain in U.S. Emergency Departments.

OBJECTIVE. CT has excellent accuracy for appendicitis but is associated with risks. Research and educational campaigns have been conducted to implement an ultrasound-first strategy for children but not for adults. The purpose of this study was to measure the use of CT and ultrasound in emergency department (ED) visits for abdominal pain and appendicitis to examine the impact of these efforts. MATERIALS AND METHODS. We analyzed data from the National Hospital Ambulatory Medical Care Survey (1997-2016). Use of CT and ultrasound was measured over time in visits for abdominal pain and visits in which appendicitis was diagnosed. Predictors of CT use were identified by means of regression analysis. RESULTS. For children, CT use increased from 1.2% (95% CI, 0.6-2.5%) in 1997, peaked in 2010 at 16.6% (95% CI, 13.8-19.6%), and decreased slightly in 2016. In adults, CT use increased steadily from 3.9% in 1997 (95% CI, 3.1-4.8%) to 37.8% (95% CI, 35.5-41.0%) in 2016. CT use increased for both pediatric and adult ED visits with a diagnosis of appendicitis, from 5.2% (95% CI, 0.7-29.5%) to 71.0% (95% CI, 43.1-88.8%) for children and 7.2% (95% CI, 2.7-17.6%) to 83.3% (95% CI, 64.1-93.3%) for adults. Children with abdominal pain and a diagnosis of appendicitis evaluated in a pediatric ED were at decreased odds (pain odds ratio, 0.6 [95% CI, 0.3-0.9]; appendicitis odds ratio, 0.2 [95% CI, 0.0-0.7]) of receiving CT than were those evaluated in general EDs. CONCLUSION. CT use has decreased in the evaluation of abdominal pain in children, perhaps because of research findings and efforts to implement an ultrasound-first strategy for suspected appendicitis. In contrast, CT use has continued to increase among adults with abdominal pain in EDs.

Predicting 3-month risk for adolescent suicide attempts among pediatric emergency department patients.

BACKGROUND: The incidence of adolescent suicide is rising in the United States, yet we have limited information regarding short-term prediction of suicide attempts. Our aim was to identify predictors of suicide attempts within 3-months of an emergency department (ED) visit. METHODS: Adolescents, ages 12-17, seeking health care at 13 pediatric EDs (Pediatric Emergency Care Applied Research Network) and one Indian Health Service Hospital in the United States were consecutively recruited. Among 10,664 approached patients, 6,448 (60%) were enrolled and completed a suicide risk survey. A subset of participants (n = 2,897) was assigned to a 3-month telephone follow-up, and 2,104 participants completed this follow-up (73% retention). Our primary outcome was a suicide attempt between the ED visit and 3-month follow-up. RESULTS: One hundred four adolescents (4.9%) made a suicide attempt between enrollment and 3-month follow-up. A large number of baseline predictors of suicide attempt were identified in bivariate analyses. The final multivariable model for the full sample included the presence of suicidal ideation during the past week, lifetime severity of suicidal ideation, lifetime history of suicidal behavior, and school connectedness. For the subgroup of adolescents who did not report recent suicidal ideation at baseline, the final model included only lifetime severity of suicidal ideation and social connectedness. Among males, the final model included only lifetime severity of suicidal ideation and past week suicidal ideation. For females, the final model included past week suicidal ideation, lifetime severity of suicidal ideation, number of past-year nonsuicidal self-injury (NSSI) incidents, and social connectedness. CONCLUSIONS: Results indicate that the key risk factors for adolescent suicide attempts differ for subgroups of adolescents defined by sex and whether or not they report recent suicidal thoughts. Results also point to the importance of school and social connectedness as protective factors against suicide attempts.

Utility of the "No Response" Option in Detecting Youth Suicide Risk in the Pediatric Emergency Department.

STUDY OBJECTIVE: We examine the characteristics of adolescents who select "no response" on a suicide screening instrument. METHODS: This study used a preexisting data set containing records of 3,388 patients aged 12 to 17 years who completed a suicide screen after presenting to the emergency department with nonpsychiatric complaints. Respondents who answered no response to at least one item without any yes responses were assigned to the no response group (n=58), whereas respondents who selected yes for any question (n=167) were assigned to the yes group. Researcher and mental health provider notes were analyzed to determine suicide risk level, presence of referral, and readiness to engage in treatment. RESULTS: Suicide risk and need for mental health referral were substantial for both groups. Clinically significant risk was identified for 84.5% of the no response group and 93.4% of the yes group, with documentation of suggested mental health referral present for 50.0% and 65.1%, respectively. Individuals in the no response group were more likely to be in 1 of the 2 earliest stages of readiness for treatment engagement (40.9% compared with 25.7% of adolescents in the yes group). CONCLUSION: To our knowledge, this is the first study to explore the relationship between a no response answer on a tablet-based screening instrument and risk for suicide as determined by a mental health provider. Although preliminary, this work indicates that youths who answer no response on suicide screening items are at elevated risk and may benefit from further evaluation or receipt of information on services. Further research is needed to better understand this population and their subsequent suicide risk.

Children and Adolescents With Suicidal Ideation and the Emergency Department.

This Viewpoint discusses the need for formal training in suicide prevention for frontline emergency clinicians and staff, including standardized screening practices, assessment and targeted interventions, and increased connection to outpatient mental health services after discharge from the emergency department.

Factors associated with participation in research conducted in a pediatric emergency department.

OBJECTIVE: To examine the association of demographic and study characteristics in eligible subjects who agree to participate compared with those who did not participate in clinical research studies in a pediatric emergency department (PED). METHODS: Information for all families approached for participation in PED-based clinical research studies during a 6-year period was recorded in an electronic database. This included demographic factors, decision to participate, primary reason for not participating, and study characteristics. Forty studies were included in this analysis. Differences in participation rate among demographic and study characteristics were examined. Multivariable logistic regression was used to predict the likelihood of participation. RESULTS: Participation rates were similar with respect to sex (50.1% in male vs 49.9% in female), whereas families with younger children were more likely to participate (mean age, 8.5 years vs 10.2 years among nonparticipants P < 0.001). White patients were more likely to participate than African American patients (54.7% vs 45.6% in African Americans, P < 0.001). The presence of compensation, brief time requirement, and older children was negatively associated with participation for moderate to very invasive studies. However, for noninvasive and mildly invasive studies, the presence of compensation and the time required were not associated with participation. CONCLUSIONS: Study characteristics including invasiveness, time required of patients, and whether compensation is offered, along with demographic factors, influence participation in clinical studies conducted in the PED. When designing a research study in the PED, these, along with novel approaches to including all races and ethnicities in PED research, should be considered.

Management of suicidal risk in the emergency department: A clinical pathway using the computerized adaptive screen for suicidal youth.

Objective: Given the critical need for efficient and tailored suicide screening for youth presenting in the emergency department (ED), this study establishes validated screening score thresholds for the Computerized Adaptive Screen for Suicidal Youth (CASSY) and presents an example of a suicide risk classification pathway. Methods: Participants were primarily from the Study One derivation cohort of the Emergency Department Screen for Teens at Risk for Suicide (ED-STARS) enrolled in collaboration with Pediatric Emergency Care Applied Research Networks (PECARN). CASSY scores corresponded to the predicted probabilities of a suicide attempt in the next 3 months and risk thresholds were classified as minimal (<1%), low (1%-5%), moderate (5%-10%), and high (>10%). CASSY scores were compared to risk thresholds derived from clinical consensus and ED complaints and dispositions. CASSY risk thresholds were also examined as predictors of future suicide attempts in the Study Two validation cohort of ED-STARS. Results: A total of 1452 teens were enrolled with a median age of 15.2 years, 59.5% were female, 55.6% were White, 22% were Black, 22.3% were Latinx, and 42.8% received public assistance. The clinical consensus suicide risk groups were strongly associated with the CASSY-predicted risk thresholds. Suicide attempts in the Study Two cohort occurred at a frequency consistent with the CASSY-predicted thresholds. Conclusions: The CASSY can be a valuable tool in providing patient-specific risk probabilities for a suicide attempt at 3 months and tailor the threshold cutoffs based on the availability of local mental health resources. We give an example of a clinical risk pathway, which should include segmentation of the ED population by medical versus psychiatric chief complaint.

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.

Maternal somatic symptoms, psychosocial correlates, and subsequent pediatric emergency department use.

BACKGROUND: Somatization is associated with increased health care use in adults. Whether mothers with somatic symptoms use more health care resources for their children has not been investigated. OBJECTIVE: This study aimed to explore the association of maternal somatic symptoms and emergency department (ED) use. DESIGN/METHODS: Mothers from a cohort of 319 mother-child dyads were screened for somatic symptoms using the Patient Health Questionnaire 15. Dyads were followed up for 3 years after the initial ED visit to record ED use. The outcome variable was ED use (lower ED use, 0-3 visits, higher ED use, 4+ visits). The primary independent variable was somatization, with a dichotomous variable analyzing the Patient Health Questionnaire 15 symptom count of less than 7 symptoms (lower somatization) and 7 or more symptoms (higher somatization [HISOM]). Secondary independent variables included demographic data, maternal major depression, and maternal difficulty in taking care of the child or themselves. Statistical analysis included bivariate and multivariate analyses. RESULTS: Mothers with HISOM symptoms did not demonstrate an increased use of the ED in bivariate analysis. Higher somatization mothers did show an increased (1) endorsement of maternal major depression symptoms and (2) maternal perception of difficulty in taking care of the child and themselves. When adjusted for these and other covariates, HISOM mothers were more likely to be in the higher ED use group (1.83; 95% confidence interval, 0.99-3.38) P = 0.055). CONCLUSIONS: Mothers with higher somatic symptom loads were more likely to screen positive for depression and to report difficulty caring for their child and for themselves. A trend toward higher use of the pediatric ED warrants further study.

Safety of a prehospital emergency medical services protocol for an alternative destination for pediatric behavioral emergencies in Alameda County.

Background: Pediatric patients with behavioral health emergencies (BHEs) are often transported to an emergency department (ED) by emergency medical services (EMS), despite having no physical medical complaints, to await psychiatric evaluation and treatment. This process leads to significant delays in their care. We examined the safety of directly transporting pediatric patients with BHEs from the field to an alternative destination of a psychiatric emergency service (PES) facility using an EMS protocol. Methods: A retrospective review from November 1, 2011, to November 1, 2016, was conducted for pediatric EMS encounters using EMS data from Alameda County, California. Our primary outcome was the safety of a prehospital alternative destination protocol. We identified the proportion of patients who required retransport to an ED within 24 h after arriving at PES (defined as a failed diversion). We also describe the mortality of all patients being transported for a BHE. Results: There were 38,241 total pediatric encounters, with 20.1% for BHEs. A total of 3122 (41%) BHE encounters met protocol criteria and were transported directly to the PES. Only 16 (0.5%) patients had a secondary transport (failed diversion) to an ED within 24 h of arrival. No patients with a BHE transported to the PES died within 30 days of the EMS encounter. Conclusion: Death and adverse clinical outcomes are extremely rare in pediatric patients using a prehospital alternative destination protocol. This information could significantly improve the care of children with BHEs.

The Cost of Universal Suicide Risk Screening for Adolescents in Emergency Departments.

Suicide is the second leading cause of death among adolescents. As nearly 20% of adolescents visit emergency departments (EDs) each year, EDs have an opportunity to identify previously unrecognized suicide risk. A novel Computerized Adaptive Screen for Suicidal Youth (CASSY) was shown in a multisite study to be predictive for suicide attempts within 3 months. This study uses site-specific data to estimate the cost of CASSY implementation with adolescents in general EDs. When used universally with all adolescents who are present and able to participate in the screening, the average cost was USD 5.77 per adolescent. For adolescents presenting with non-behavioral complaints, the average cost was USD 2.60 per adolescent. Costs were driven primarily by time and personnel required for the further evaluation of suicide risk for those screening positive. Thus, universal screening using the CASSY, at very low costs relative to the cost of an ED visit, can facilitate services needed for at-risk adolescents.

Physical restraint use in children with mental and behavioral health emergencies in the prehospital setting.

Objective: Emergency medical services (EMS) transport for mental and behavioral health (MBH) emergencies occurs frequently in children, yet little is understood regarding prehospital physical restraint use despite the potential for serious adverse events. We aim to describe restraint use prevalence and primary impressions among children with MBH emergencies. Methods: This is a retrospective cross-sectional study of children with MBH emergencies evaluated by Alameda County (ALCO), California EMS from January 1, 2012 to December 31, 2018. Patient demographics and clinical variables were collected from the EMS records including sex, age at time of encounter, year of encounter, transport destination, medication use, and primary impression(s). The primary outcome was the use of physical restraints. Descriptive statistics were used to characterize the primary outcome and associated demographic and diagnostic features, as well as temporal use patterns. Sex and age were compared between restrained and non-restrained youth using chi-square analysis. Results: Over the 7-year study period, ALCO EMS transported 9775 children with MBH emergencies. Of these transports, 1205 (12.3%) were physically restrained. Most children restrained had the primary impression of "behavioral/psychiatric crisis" (51.1%), "psychiatric crisis" (27.4%), and "behavioral-other" (12.4%) and the remaining children (9.1%) had a non-psychiatric/behavioral health primary impression. Over time, there was no statistically significant change in either number of children with MBH emergencies transported or physical restraint rate. Conclusions: More than 1 in 8 children with MBH emergencies are being physically restrained during EMS transport. Restraint rate did not substantially change over time. Further studies to understand existing restraint rates and EMS resources available to address acute agitation in children are needed to inform quality and care enhancing initiatives.

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.
