Access to treatment for children with attention-deficit hyperactivity disorder (ADHD) was examined in the general health, specialty mental health, and informal care sectors. Special education students in a Florida school district were screened for ADHD, and high-risk children and their parents completed diagnostic and services assessment interviews. Female gender, minority status, and rural residence lowered the probability of ADHD service use in the general health sector. Use of services in the mental health and informal sectors was predicted by a child's need for services. Further study is needed to identify barriers to service use at the parental or gatekeeper level for this common disorder among children. [ABSTRACT FROM AUTHOR]

Objective: To examine whether clinical severity is greater among children receiving attention-deficit/hyperactivity disorder (ADHD) care in primary care compared with those in specialty mental health clinics, and to examine how care processes and clinical outcomes vary by sector across three 6-month time intervals.Method: This was a longitudinal cohort study of 530 children aged 5 to 11 years receiving ADHD care in primary care or specialty mental health clinics from November 2004 through September 2006 in a large, countywide managed care Medicaid program.Results: Clinical severity at study entry did not differ between children who received ADHD care in solely primary or specialty mental health care clinics. At three 6-month intervals, receipt of no care ranged from 34% to 44%, and unmet need for mental health services ranged from 13% to 20%. In primary care, 80% to 85% of children had at least one stimulant prescription filled and averaged one to two follow-up visits per year. Less than one-third of children in specialty mental health clinics received any stimulant medication, but all received psychosocial interventions averaging more than five visits per month. In both sectors, stimulant medication refill prescription persistence was poor (31%-49%). With few exceptions, ADHD diagnosis, impairment, academic achievement, parent distress, and parent-reported treatment satisfaction, perceived benefit, and improved family functioning did not differ between children who remained in care and those who received no care.Conclusion: Areas for quality improvement are alignment of clinical severity with provider type, follow-up visits, stimulant use in specialty mental health, agency data infrastructure to document delivery of evidence-based psychosocial treatment, and stimulant medication refill prescription persistence.

Importance: Suicide is a leading cause of death among young people. Accurate detection of self-injurious thoughts and behaviors (SITB) underpins equity in youth suicide prevention., Objectives: To compare methods of detecting SITB using structured electronic health information and measure algorithmic performance across demographics., Design, Setting, and Participants: This cross-sectional study used medical records among youths aged 6 to 17 years with at least 1 mental health-related emergency department (ED) visit in 2017 to 2019 to an academic health system in Southern California serving 787 000 unique individuals each year. Analyses were conducted between January and September 2023., Exposures: Multiexpert electronic health record review ascertained the presence of SITB using the Columbia Classification Algorithm of Suicide Assessment. Random forest classifiers with nested cross-validation were developed using (1) International Statistical Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) codes for nonfatal suicide attempt and self-harm and chief concern and (2) all available structured data, including diagnoses, medications, and laboratory tests., Main Outcome and Measures: Detection performance was assessed overall and stratified by age group, sex, and race and ethnicity., Results: The sample comprised 2702 unique youths with an MH-related ED visit (1384 youths who identified as female [51.2%]; 131 Asian [4.8%], 266 Black [9.8%], 719 Hispanic [26.6%], 1319 White [48.8%], and 233 other race [8.6%]; median [IQR] age, 14 [12-16] years), including 898 children and 1804 adolescents. Approximately half of visits were related to SITB (1286 visits [47.6%]). Sensitivity of SITB detection using only codes and chief concern varied by age group and increased until age 15 years (6-9 years: 59.3% [95% CI, 48.5%-69.5%]; 10-12 years: 69.0% [95% CI, 63.8%-73.9%]; 13-15 years: 88.4% [95% CI, 85.1%-91.2%]; 16-17 years: 83.1% [95% CI, 79.1%-86.6%]), while specificity remained constant. The area under the receiver operating characteristic curve (AUROC) was lower among preadolescents (0.841 [95% CI, 0.815-0.867]) and male (0.869 [95% CI, 0.848-0.890]), Black (0.859 [95% CI, 0.813-0.905]), and Hispanic (0.861 [95% CI, 0.831-0.891]) youths compared with adolescents (0.925 [95% CI, 0.912-0.938]), female youths (0.923 [95% CI, 0.909-0.937]), and youths of other races and ethnicities (eg, White: 0.901 [95% CI, 0.884-0.918]). Augmented classification (ie, using all available structured data) outperformed classification with codes and chief concern alone (AUROC, 0.975 [95% CI, 0.968-0.980] vs 0.894 [95% CI, 0.882-0.905]; P < .001)., Conclusions and Relevance: In this study, diagnostic codes and chief concern underestimated SITB prevalence, particularly among minoritized youths. These results suggest that priority on algorithmic fairness in suicide prevention strategies must extend to accurate detection of youths with suicide-related emergencies.

Importance: Suicide is a leading cause of death among US youths, and mental health disorders are a known factor associated with increased suicide risk. Knowledge about potential sociodemographic differences in documented mental health diagnoses may guide prevention efforts., Objective: To examine the association of documented mental health diagnosis with (1) sociodemographic and clinical characteristics, (2) precipitating circumstances, and (3) mechanism among youth suicide decedents., Design, Setting, and Participants: This retrospective, cross-sectional study of youth suicide decedents aged 10 to 24 years used data from the Centers for Disease Control and Prevention National Violent Death Reporting System from 2010 to 2021. Data analysis was conducted from January to November 2023., Exposures: Sociodemographic characteristics, clinical characteristics, precipitating circumstances, and suicide mechanism., Main Outcomes and Measures: The primary outcome was previously documented presence of a mental health diagnosis. Associations were evaluated by multivariable logistic regression., Results: Among 40 618 youth suicide decedents (23 602 aged 20 to 24 years [58.1%]; 32 167 male [79.2%]; 1190 American Indian or Alaska Native [2.9%]; 1680 Asian, Native Hawaiian, or Other Pacific Islander [4.2%]; 5118 Black [12.7%]; 5334 Hispanic [13.2%]; 35 034 non-Hispanic; 30 756 White [76.1%]), 16 426 (40.4%) had a documented mental health diagnosis and 19 027 (46.8%) died by firearms. The adjusted odds of having a mental health diagnosis were lower among youths who were American Indian or Alaska Native (adjusted odds ratio [aOR], 0.45; 95% CI, 0.39-0.51); Asian, Native Hawaiian, or Other Pacific Islander (aOR, 0.58; 95% CI, 0.52-0.64); and Black (aOR, 0.62; 95% CI, 0.58-0.66) compared with White youths; lower among Hispanic youths (aOR, 0.76; 95% CI, 0.72-0.82) compared with non-Hispanic youths; lower among youths aged 10 to 14 years (aOR, 0.70; 95% CI, 0.65-0.76) compared with youths aged 20 to 24 years; and higher for females (aOR, 1.64; 95% CI, 1.56-1.73) than males. A mental health diagnosis was documented for 6308 of 19 027 youths who died by firearms (33.2%); 1691 of 2743 youths who died by poisonings (61.6%); 7017 of 15 331 youths who died by hanging, strangulation, or suffocation (45.8%); and 1407 of 3181 youths who died by other mechanisms (44.2%). Compared with firearm suicides, the adjusted odds of having a documented mental health diagnosis were higher for suicides by poisoning (aOR, 1.70; 95% CI, 1.62-1.78); hanging, strangulation, and suffocation (aOR, 2.78; 95% CI, 2.55-3.03); and other mechanisms (aOR, 1.59; 95% CI, 1.47-1.72)., Conclusions and Relevance: In this cross-sectional study, 3 of 5 youth suicide decedents did not have a documented preceding mental health diagnosis; the odds of having a mental health diagnosis were lower among racially and ethnically minoritized youths than White youths and among firearm suicides compared with other mechanisms. These findings underscore the need for equitable identification of mental health needs and universal lethal means counseling as strategies to prevent youth suicide.

Purpose: Alcohol use disorder (AUD) is a pediatric-onset condition needing timely, effective treatment. Medications for AUD are part of nationally recommended treatments for youth. This study measured receipt of medications and behavioral health services for AUD and subsequent retention in care., Methods: This retrospective cohort study used claims data from > 4.7 million publicly insured youth aged 13-22 years in 15 states from 2014-2019. Timely treatment was defined as receipt of medication (naltrexone, acamprosate, or disulfiram) and/or behavioral health services within 30 days of incident AUD diagnosis. Associations of age and other characteristics with timely treatment were identified using modified Poisson regression. Retention in care (i.e., no period ≥ 60 days without claims) was studied using Cox regression., Results: Among 14,194 youth with AUD, 10,851 (76.4%) received timely treatment. Only 2.1% of youth received medication (alone or in combination); nearly all (97.9%) received behavioral health services only. Older (aged 16-17 years) and younger adolescents (aged 13-15 years) were 0.13 (95% confidence interval [CI], 0.07-0.26) and 0.24 (95% CI, 0.11-0.51) times as likely, respectively, to receive medications than young adults aged ≥ 21 years. Median retention in care for youth receiving medications was 119 days (interquartile range, 54-321) compared with 108 days (interquartile range, 43-243) for behavioral health services alone (p = .126). Young adults aged ≥ 18 years were 1.12 (95% CI, 1.06-1.18) times as likely to discontinue treatment compared with adolescents aged < 18 years., Discussion: This study found that more than seven in 10 youth received AUD treatment but only two in 100 received medications. Future studies should further characterize the effectiveness of medications and determine whether low rates of receipt represent underuse., (Copyright © 2023 Society for Adolescent Health and Medicine.

Objective: Geography may influence the relationships of predictors for suicidal ideation (SI) and suicide attempts (SA) in children and youth., Method: This is a nationwide retrospective cohort study of 124,424 individuals less than 25 years of age using commercial claims data (2011-2015) from the Health Care Cost Institute. Outcomes were time to SI or SA within 3 months after the indexed mental health or substance use disorder (MH/SUD) outpatient visit. Predictors included sociodemographic and clinical characteristics up to 3 years before the index event., Results: At each follow-up time period, rates of SI and SA varied by the US geographic division ( p < .001), and the Mountain Division consistently had the highest rates for both SI and SA (5.44%-10.26% for SI; 0.70%-2.82% for SA). Having MH emergency department (ED) visits in the past year increased the risk of SI by 28% to 65% for individuals residing in the New England, Mid-Atlantic, East North Central, West North Central, and East South Central Divisions. The main effects of geographic divisions were significant for SA (p<0.001). Risk of SA was lower in New England, Mid-Atlantic, South Atlantic, and Pacific (hazard ratios = 0.57, 0.51, 0.67, and 0.79, respectively) and higher in the Mountain Division (hazard ratio = 1.46)., Conclusion: To understand the underlying mechanisms driving the high prevalence of SI and SA in the Mountain Division and the elevated risk of SI after having MH ED visits, future research examining regional differences in risks for SI and SA should include indicators of access to MH ED care and other social determinants of health., Competing Interests: Disclosure: Dr. Pathak is the Cofounder of Iris OB Health Inc., New York and has equity ownership.

Background: Although suicide is a leading cause of death among children, the optimal approach for using health care data sets to detect suicide-related emergencies among children is not known., Objective: This study aimed to assess the performance of suicide-related International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) codes and suicide-related chief complaint in detecting self-injurious thoughts and behaviors (SITB) among children compared with clinician chart review. The study also aimed to examine variations in performance by child sociodemographics and type of self-injury, as well as develop machine learning models trained on codified health record data (features) and clinician chart review (gold standard) and test model detection performance., Methods: A gold standard classification of suicide-related emergencies was determined through clinician manual review of clinical notes from 600 emergency department visits between 2015 and 2019 by children aged 10 to 17 years. Visits classified with nonfatal suicide attempt or intentional self-harm using the Centers for Disease Control and Prevention surveillance case definition list of ICD-10-CM codes and suicide-related chief complaint were compared with the gold standard classification. Machine learning classifiers (least absolute shrinkage and selection operator-penalized logistic regression and random forest) were then trained and tested using codified health record data (eg, child sociodemographics, medications, disposition, and laboratory testing) and the gold standard classification. The accuracy, sensitivity, and specificity of each detection approach and relative importance of features were examined., Results: SITB accounted for 47.3% (284/600) of the visits. Suicide-related diagnostic codes missed nearly one-third (82/284, 28.9%) and suicide-related chief complaints missed more than half (153/284, 53.9%) of the children presenting to emergency departments with SITB. Sensitivity was significantly lower for male children than for female children (0.69, 95% CI 0.61-0.77 vs 0.84, 95% CI 0.78-0.90, respectively) and for preteens compared with adolescents (0.66, 95% CI 0.54-0.78 vs 0.86, 95% CI 0.80-0.92, respectively). Specificity was significantly lower for detecting preparatory acts (0.68, 95% CI 0.64-0.72) and attempts (0.67, 95% CI 0.63-0.71) than for detecting ideation (0.79, 95% CI 0.75-0.82). Machine learning-based models significantly improved the sensitivity of detection compared with suicide-related codes and chief complaint alone. Models considering all 84 features performed similarly to models considering only mental health-related ICD-10-CM codes and chief complaints (34 features) and models considering non-ICD-10-CM code indicators and mental health-related chief complaints (53 features)., Conclusions: The capacity to detect children with SITB may be strengthened by applying a machine learning-based approach to codified health record data. To improve integration between clinical research informatics and child mental health care, future research is needed to evaluate the potential benefits of implementing detection approaches at the point of care and identifying precise targets for suicide prevention interventions in children., (©Juliet Beni Edgcomb, Chi-hong Tseng, Mengtong Pan, Alexandra Klomhaus, Bonnie T Zima.

Objectives: To examine how timing of the first outpatient mental health (MH) visit after a pediatric firearm injury varies by sociodemographic and clinical characteristics., Methods: We retrospectively studied children aged 5 to 17 years with a nonfatal firearm injury from 2010 to 2018 using the IBM Watson MarketScan Medicaid database. Logistic regression estimated the odds of MH service use in the 6 months after injury, adjusted for sociodemographic and clinical characteristics. Cox proportional hazard models, stratified by previous MH service use, evaluated variation in timing of the first outpatient MH visit by sociodemographic and clinical characteristics., Results: After a firearm injury, 958 of 2613 (36.7%) children used MH services within 6 months; of these, 378 of 958 (39.5%) had no previous MH service use. The adjusted odds of MH service use after injury were higher among children with previous MH service use (adjusted odds ratio, 10.41; 95% confidence interval [CI], 8.45-12.82) and among non-Hispanic white compared with non-Hispanic Black children (adjusted odds ratio, 1.29; 95% CI, 1.02-1.63). The first outpatient MH visit after injury occurred sooner among children with previous MH service use (adjusted hazard ratio, 6.32; 95% CI, 5.45-7.32). For children without previous MH service use, the first MH outpatient visit occurred sooner among children with an MH diagnosis made during the injury encounter (adjusted hazard ratio, 2.72; 95% CI, 2.04-3.65)., Conclusions: More than 3 in 5 children do not receive MH services after firearm injury. Previous engagement with MH services and new detection of MH diagnoses during firearm injury encounters may facilitate timelier connection to MH services after injury., (Copyright © 2023 by the American Academy of Pediatrics.)

Pediatric anxiety disorders (AD) are prevalent disorders with an impact on all aspects of a child's life and functioning. 1 Although evidence supports commonly used treatments, there are notable concerns with the research to date. 2 Heterogeneity in outcome selection, measurement, analysis, and reporting is a contributing factor to the hinderance of the translation of research into clinical practice. 3 Recognition for outcome standardization in pediatric mental health disorders is evolving and there are several initiatives of importance, including the International Consortium for Health Outcomes Measurement (ICHOM), which has developed standardized outcome sets for use in the routine clinical mental health treatment of children and adolescents. 4 Similarly, the International Alliance of Mental Health Research Funders 5 advocate for use of 1 specific outcome measurement instrument (OMI) in the youth mental health research that they fund. Development of a Core Outcome Set (COS), a minimal set of outcomes that should be measured and reported in clinical trials, has been a solution in other areas of medicine to address heterogeneity in outcome selection and measurement across trials. 6 The Core Outcomes and Measures in Pediatric Anxiety Clinical Trials (COMPACT) Initiative will develop a harmonized, evidence- and consensus-based COS that is meaningful to youth and families for use in future trials in pediatric AD., (Copyright © 2023 American Academy of Child and Adolescent Psychiatry.

Objectives: To examine how outpatient mental health (MH) follow-up after a pediatric MH emergency department (ED) discharge varies by patient characteristics and to evaluate the association between timely follow-up and return encounters., Methods: We conducted a retrospective study of 28 551 children aged 6 to 17 years with MH ED discharges from January 2018 to June 2019, using the IBM Watson MarketScan Medicaid database. Odds of nonemergent outpatient follow-up, adjusted for sociodemographic and clinical characteristics, were estimated using logistic regression. Cox proportional hazard models were used to evaluate the association between timely follow-up and risk of return MH acute care encounters (ED visits and hospitalizations)., Results: Following MH ED discharge, 31.2% and 55.8% of children had an outpatient MH visit within 7 and 30 days, respectively. The return rate was 26.5% within 6 months. Compared with children with no past-year outpatient MH visits, those with ≥14 past-year MH visits had 9.53 odds of accessing follow-up care within 30 days (95% confidence interval [CI], 8.75-10.38). Timely follow-up within 30 days was associated with a 26% decreased risk of return within 5 days of the index ED discharge (hazard ratio, 0.74; 95% CI, 0.63-0.91), followed by an increased risk of return thereafter., Conclusions: Connection to outpatient care within 7 and 30 days of a MH ED discharge remains poor, and children without prior MH outpatient care are at highest risk for poor access to care. Interventions to link to outpatient MH care should prioritize follow-up within 5 days of an MH ED discharge., (Copyright © 2023 by the American Academy of Pediatrics.)

Objective: This study aimed to examine changes in child emergency department (ED) discharges and hospitalizations for primary general medical (GM) and primary psychiatric disorders; prevalence of psychiatric disorders among acute care encounters; and change in acute mental health (MH) care encounters by disorder type and, within these categories, by child sociodemographic characteristics before and after statewide COVID-19–related school closure orders., Methods: This retrospective, cross-sectional cohort study used the Pediatric Health Information System database to assess percent changes in ED discharges and hospitalizations (N=2,658,474 total encounters) among children ages 3–17 years in 44 U.S. children’s hospitals in 2020 compared with 2019, by using matched data for 36- and 12-calendar-week intervals., Results: Decline in MH ED discharges accounted for about half of the decline in ED discharges and hospitalizations for primary GM disorders (−24.8% vs. −49.1%), and MH hospitalizations declined 3.4 times less (−8.0% vs. −26.8%) in 2020. Suicide attempt or self-injury and depressive disorders accounted for &gt;50% of acute MH care encounters before and after the statewide school closures. The increase in both ED discharges and hospitalizations for suicide attempt or self-injury was 5.1 percentage points (p&lt;0.001). By fall 2020, MH hospitalizations for suicide attempt or self-injury rose by 41.7%, with a 43.8% and 49.2% rise among adolescents and girls, respectively., Conclusions: Suicide or self-injury and depressive disorders drove acute MH care encounters in 44 U.S. children’s hospitals after COVID-19–related school closures. Research is needed to identify continuing risk indicators (e.g., sociodemographic characteristics, psychiatric disorder types, and social determinants of health) of acute child MH care.

Objective: To compare new mental health diagnoses (NMHD) in children after a firearm injury versus following a motor vehicle collision (MVC)., Background: A knowledge gap exists regarding childhood mental health diagnoses following firearm injuries, notably in comparison to other forms of traumatic injury., Methods: We utilized Medicaid MarketScan claims (2010-2016) to conduct a matched case-control study of children ages 3 to 17 years. Children with firearm injuries were matched with up to 3 children with MVC injuries. Severity was determined by injury severity score and emergency department disposition. We used multivariable logistic regression to measure the association of acquiring a NMHD diagnosis in the year postinjury after firearm and MVC mechanisms., Results: We matched 1450 children with firearm injuries to 3691 children with MVC injuries. Compared to MVC injuries, children with firearm injuries were more likely to be black, have higher injury severity score, and receive hospital admission from the emergency department ( P <0.001). The adjusted odds ratio (aOR) of NMHD diagnosis was 1.55 [95% confidence interval (95% CI): 1.33-1.80] greater after firearm injuries compared to MVC injuries. The odds of a NMHD were higher among children admitted to the hospital compared to those discharged. The increased odds of NMHD after firearm injuries was driven by increases in substance-related and addictive disorders (aOR: 2.08; 95% CI: 1.63-2.64) and trauma and stressor-related disorders (aOR: 2.07; 95% CI: 1.55-2.76)., Conclusions: Children were found to have 50% increased odds of having a NMHD in the year following a firearm injury as compared to MVC. Programmatic interventions are needed to address children's mental health following firearm injuries., Competing Interests: The authors report no conflicts of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

While many standardized assessment measures exist to track child mental health treatment outcomes, the degree to which such tools have been adequately tested for reliability and validity across race, ethnicity, and class is uneven. This paper examines the corpus of published tests of psychometric properties for the ten standardized measures used in U.S. child outpatient care, with focus on breadth of testing across these domains. Our goal is to assist care providers, researchers, and legislators in understanding how cultural mismatch impacts measurement accuracy and how to select tools appropriate to the characteristics of their client populations. We also highlight avenues of needed research for measures that are in common use. The list of measures was compiled from (1) U.S. state Department of Mental Health websites; (2) a survey of California county behavioral health agency directors; and (3) exploratory literature scans of published research. Ten measures met inclusion criteria; for each one a systematic review of psychometrics literature was conducted. Diversity of participant research samples was examined as well as differences in reliability and validity by gender, race or ethnicity, and socio-economic class. All measures showed adequate reliability and validity, however half lacked diverse testing across all three domains and all lacked testing with Asian American/Pacific Islander and Native American children. ASEBA, PSC, and SDQ had the broadest testing., (© 2021. The Author(s).)

Objective: To measure univariate and covariate-adjusted trends in children's mental health-related emergency department (MH-ED) use across geographically diverse areas of the U.S. during the first wave of the Coronavirus-2019 (COVID-19) pandemic., Method: This is a retrospective, cross-sectional cohort study using electronic health records from four academic health systems, comparing percent volume change and adjusted risk of child MH-ED visits among children aged 3-17 years, matched on 36-week (3/18/19-11/25/19 vs. 3/16/20-11/22/20) and 12-week seasonal time intervals. Adjusted incidence rate ratios (IRR) were calculated using multivariate Poisson regression., Results: Visits declined during spring-fall 2020 ( n  = 3892 vs. n  = 5228, -25.5%) and during spring ( n  = 1051 vs. n  = 1839, -42.8%), summer ( n  = 1430 vs. n  = 1469, -2.6%), and fall ( n  = 1411 vs. n  = 1920, -26.5%), compared with 2019. There were greater declines among males (28.2% vs. females -22.9%), children 6-12-year (-28.6% vs. -25.9% for 3-5 years and -22.9% for 13-17 years), and Black children (-34.8% vs. -17.7% to -24.9%). Visits also declined for developmental disorders (-17.0%) and childhood-onset disorders (e.g., attention deficit and hyperactivity disorders; -18.0%). During summer-fall 2020, suicide-related visits rose (summer +29.8%, fall +20.4%), but were not significantly elevated from 2019 when controlling for demographic shifts. In contrast, MH-ED use during spring-fall 2020 was significantly reduced for intellectual disabilities (IRR 0.62 [95% CI 0.47-0.86]), developmental disorders (IRR 0.71 [0.54-0.92]), and childhood-onset disorders (IRR 0.74 [0.56-0.97])., Conclusions: The early pandemic brought overall declines in child MH-ED use alongside co-occurring demographic and diagnostic shifts. Children vulnerable to missed detection during instructional disruptions experienced disproportionate declines, suggesting need for future longitudinal research in this population., (© 2022 The Authors.

Background and Objectives: Children seeking care in the emergency department (ED) for mental health conditions are at risk for prolonged length of stay (LOS). A more contemporary description of trends and visit characteristics associated with prolonged ED LOS at the national level is lacking in the literature. Our objectives were to (1) compare LOS trends for pediatric mental health versus non-mental health ED visits and (2) explore patient-level characteristics associated with prolonged LOS for mental health ED visits., Methods: We conducted an observational analysis of ED visits among children 6 to 17 years of age using the National Hospital Ambulatory Medical Care Survey (2005-2015). We assessed trends in rates of prolonged LOS and the association between prolonged LOS and demographic and clinical characteristics (race and ethnicity, payer type, and presence of a concurrent physical health diagnosis) using descriptive statistics and survey-weighted logistic regression., Results: From 2005 to 2015, rates of prolonged LOS for pediatric mental health ED visits increased over time from 16.3% to 24.6% (LOS >6 hours) and 5.3% to 12.7% (LOS >12 hours), in contrast to non-mental health visits for which LOS remained stable. For mental health visits, Hispanic ethnicity was associated with an almost threefold odds of LOS >12 hours (odds ratio 2.74; 95% confidence interval 1.69-4.44); there was no difference in LOS by payer type., Conclusions: The substantial rise in prolonged LOS for mental health ED visits and disparity for Hispanic children suggest worsening and inequitable access to definitive pediatric mental health care. Policy makers and health systems should work to provide equitable and timely access to pediatric mental health care., Competing Interests: POTENTIAL CONFLICT OF INTEREST: The authors have indicated they have no potential conflicts of interest to disclose., (Copyright © 2021 by the American Academy of Pediatrics.)

Measurement-based care is conceptualized as a driver for quality improvement. The triple aim in the National Quality Strategy purposively muddles the population levels to provide a health policy goal that is encompassing, transactional, and will stimulate change. Specification of the population level has implications for the purpose, proposed target mechanisms that drive quality improvement, methodologic challenges, and implications for program evaluation and data interpretation.

Objective: To examine how characteristics vary between children with any mental health (MH) diagnosis who have typical spending and the highest spending; to identify independent predictors of highest spending; and to examine drivers of spending groups., Methods: This retrospective analysis utilized 2016 Medicaid claims from 11 states and included 775,945 children ages 3 to 17 years with any MH diagnosis and at least 11 months of continuous coverage. We compared demographic characteristics and Medicaid expenditures based on total health care spending: the top 1% (highest-spending) and remaining 99% (typical-spending). We used chi-squared tests to compare the 2 groups and adjusted logistic regression to identify independent predictors of being in the top 1% highest-spending group., Results: Children with MH conditions accounted for 55% of Medicaid spending among 3- to 17-year olds. Patients in the highest-spending group were more likely to be older, have multiple MH conditions, and have complex chronic physical health conditions (P <.001). The highest-spending group had $164,003 per-member-per-year (PMPY) in total health care spending, compared to $6097 PMPY in the typical-spending group. Ambulatory MH services contributed the largest proportion (40%) of expenditures ($2455 PMPY) in the typical-spending group; general health hospitalizations contributed the largest proportion (36%) of expenditures ($58,363 PMPY) in the highest-spending group., Conclusions: Among children with MH conditions, mental and physical health comorbidities were common and spending for general health care outpaced spending for MH care. Future research and quality initiatives should focus on integrating MH and physical health care services and investigate whether current spending on MH services supports high-quality MH care., (Copyright © 2020 Academic Pediatric Association.

Objectives: Emergency department (ED) utilization is often used as an indicator of poor chronic disease control and/or poor quality of care. We sought to determine if 2 ED utilization measures identify clinically or demographically different populations of children., Study Design: Retrospective cohort study utilizing IBM Health/Truven MarketScan Medicaid data., Methods: Children and adolescents were categorized based on the presence and complexity of chronic medical conditions using the 3M Clinical Risk Group system. Children and adolescents were categorized as high ED utilizers using 2 measures: (1) ED reliance (EDR) (number of ED visits / [number of ED visits + number of ambulatory visits]; EDR >0.33 = high utilizer) and (2) visit counts (≥3 ED visits = high utilizer). Logistic regression models identified patient factors associated with each of our outcome measures., Results: A total of 5,438,541 children and adolescents were included; 65% were without chronic disease (WO-CD), 32% had noncomplex chronic disease (NC-CD), and 3% had complex chronic disease (C-CD). EDR identified 18% as frequent utilizers compared with 7% by the visit count measure. In the visit count model, children younger than 2 years and those classified as WO-CD and NC-CD were less likely to be identified as high utilizers. Conversely, in the EDR model, children and adolescents 2 years and older and those classified as WO-CD and NC-CD were more likely to be classified as high utilizers., Conclusions: The ED utilization measures identify clinically and demographically different groups of patients. Future studies should consider the medical complexity of the population being studied before choosing the most appropriate measure to employ.

Objectives: A national quality measure in the Child Core Set is used to assess whether pediatric patients hospitalized for a mental illness receive timely follow-up care. In this study, we examine the relationship between adherence to the quality measure and repeat use of the emergency department (ED) or repeat hospitalization for a primary mental health condition., Methods: We used the Truven MarketScan Medicaid Database 2015-2016, identifying hospitalizations with a primary diagnosis of depression, bipolar disorder, psychosis, or anxiety for patients aged 6 to 17 years. Primary predictors were outpatient follow-up visits within 7 and 30 days. The primary outcome was time to subsequent mental health-related ED visit or hospitalization. We conducted bivariate and multivariate analyses using Cox proportional hazard models to assess relationships between predictors and outcome., Results: Of 22 844 hospitalizations, 62.0% had 7-day follow-up, and 82.3% had 30-day follow-up. Subsequent acute use was common, with 22.4% having an ED or hospital admission within 30 days and 54.8% within 6 months. Decreased likelihood of follow-up was associated with non-Hispanic or non-Latino black race and/or ethnicity, fee-for-service insurance, having no comorbidities, discharge from a medical or surgical unit, and suicide attempt. Timely outpatient follow-up was associated with increased subsequent acute care use (hazard ratio [95% confidence interval]: 7 days: 1.20 [1.16-1.25]; 30 days: 1.31 [1.25-1.37]). These associations remained after adjusting for severity indicators., Conclusions: Although more than half of patients received follow-up within 7 days, variations across patient population suggest that care improvements are needed. The increased hazard of subsequent use indicates the complexity of treating these patients and points to potential opportunities to intervene at follow-up visits., Competing Interests: POTENTIAL CONFLICT OF INTEREST: The authors have indicated they have no potential conflicts of interest to disclose., (Copyright © 2020 by the American Academy of Pediatrics.)

Objectives: To describe patterns of overall, within-household, and community adverse childhood experiences (ACEs) among children in vulnerable neighborhoods and to identify which individual ACEs, over and above overall ACE level, predict need for behavioral health services., Study Design: This was a cross-sectional study that used a sample of 257 children ages 3-16 years who were seeking primary care services with co-located mental healthcare services at 1 of 2 clinics in Chicago, Illinois. The outcome variable was need for behavioral health services (Pediatric Symptom Checklist score ≥28). The independent variables were ACEs, measured with an adapted, 28-item version of the Traumatic Events Screening Inventory., Results: Six ACE items were individually predictive of a clinical-range Pediatric Symptom Checklist score after adjusting for sociodemographic covariates: emotional abuse or neglect (OR 2.93, 95% CI 1.32-6.52, P < .01), natural disaster (OR 3.89, 95% CI 1.18-12.76, P = .02), forced separation from a parent or caregiver (OR 2.95, 95% CI 1.50-5.83, P < .01), incarceration of a family member (OR 2.43, 95% CI 1.20-4.93, P = .01), physical attack (OR 2.84, 95% CI 1.32-6.11, P < .01), and community violence (OR 2.35, 95% CI 1.18-4.65, P = .01). After adjusting for overall ACE level, only 1 item remained statistically significant: forced separation from a parent or caregiver (OR 2.44, 95% CI 1.19-5.01, P = .02)., Conclusions: ACEs that disrupt attachment relationships between children and their caregivers are a significant predictor of risk for child emotional or behavioral problems., (Copyright © 2020 Elsevier Inc.

Objective: To investigate predictors of psychiatric hospital readmission of children and adolescents, a systematic review and meta-analysis was conducted., Methods: Following PRISMA statement guidelines, a systematic literature search of articles published between 1997 and 2018 was conducted in PubMed/MEDLINE, Google Scholar, and PsycINFO for original peer-reviewed articles investigating predictors of psychiatric hospital readmission among youths (<18 years old). Effect sizes were extracted and combined by using random-effects meta-analysis. Covariates were investigated with meta-regression and subgroup analyses., Results: Thirty-three studies met inclusion criteria, containing information on 83,361 children and adolescents, of which raw counts of readmitted vs. non-readmitted youths were available for 76,219. Of these youths, 13.2% (N=10,076) were readmitted. The mean±SD study follow-up was 15.9±15.0 months, and time to readmission was 13.1±12.8 months. Readmission was associated with, but not limited to, suicidal ideation at index hospitalization (pooled odds ratio [OR pooled ]=2.35, 95% confidence interval [CI]=1.64-3.37), psychotic disorders (OR pooled =1.87, 95% CI=1.53-2.28), prior hospitalization (OR pooled =2.51, 95% CI=1.76-3.57), and discharge to residential treatment (OR pooled =1.84, 95% CI=1.07-3.16). There was evidence of moderate study bias. Prior investigations were methodologically and substantively heterogeneous, particularly for measurement of family-level factors., Conclusions: Interventions to reduce child psychiatric readmissions should place priority on youths with indicators of high clinical severity, particularly with a history of suicidality, psychiatric comorbidity, prior hospitalization, and discharge to residential treatment. Standardization of methods to determine prevalence rates of readmissions and their predictors is needed to mitigate potential biases and inform a national strategy to reduce repeated child psychiatric hospital readmissions.

Importance: Nonfatal opioid overdose may be a critical touch point when youths who have never received a diagnosis of opioid use disorder can be engaged in treatment. However, the extent to which youths (adolescents and young adults) receive timely evidence-based treatment following opioid overdose is unknown., Objective: To identify characteristics of youths who experience nonfatal overdose with heroin or other opioids and to assess the percentage of youths receiving timely evidence-based treatment., Design, Setting, and Participants: This retrospective cohort study used the 2009-2015 Truven-IBM Watson Health MarketScan Medicaid claims database from 16 deidentified states representing all US census regions. Data from 4 039 216 Medicaid-enrolled youths aged 13 to 22 years were included and were analyzed from April 20, 2018, to March 21, 2019., Exposures: Nonfatal incident and recurrent opioid overdoses involving heroin or other opioids., Main Outcomes and Measures: Receipt of timely addiction treatment (defined as a claim for behavioral health services, for buprenorphine, methadone, or naltrexone prescription or administration, or for both behavioral health services and pharmacotherapy within 30 days of incident overdose). Sociodemographic and clinical characteristics associated with receipt of timely treatment as well as with incident and recurrent overdoses were also identified., Results: Among 3791 youths with nonfatal opioid overdose, 2234 (58.9%) were female, and 2491 (65.7%) were non-Hispanic white. The median age was 18 years (interquartile range, 16-20 years). The crude incident opioid overdose rate was 44.1 per 100 000 person-years. Of these 3791 youths, 1001 (26.4%) experienced a heroin overdose; the 2790 (73.6%) remaining youths experienced an overdose involving other opioids. The risk of recurrent overdose among youths with incident heroin involvement was significantly higher than that among youths with other opioid overdose (adjusted hazard ratio, 2.62; 95% CI, 2.14-3.22), and youths with incident heroin overdose experienced recurrent overdose at a crude rate of 20 700 per 100 000 person-years. Of 3606 youths with opioid-related overdose and continuous enrollment for at least 30 days after overdose, 2483 (68.9%) received no addiction treatment within 30 days after incident opioid overdose, whereas only 1056 youths (29.3%) received behavioral health services alone, and 67 youths (1.9%) received pharmacotherapy. Youths with heroin overdose were significantly less likely than youths with other opioid overdose to receive any treatment after their overdose (adjusted odds ratio, 0.64; 95% CI, 0.49-0.83)., Conclusions and Relevance: After opioid overdose, less than one-third of youths received timely addiction treatment, and only 1 in 54 youths received recommended evidence-based pharmacotherapy. Interventions are urgently needed to link youths to treatment after overdose, with priority placed on improving access to pharmacotherapy.

Objective: To examine trends in mental health (MH) visits to pediatric emergency departments (EDs) and identify whether ED disposition varies by presence of a hospital inpatient psychiatric unit (IPU)., Study Design: Cross-sectional study of 8,479,311 ED visits to 35 children's hospitals from 2012 to 2016 for patients aged 3 to 21 years with a primary MH or non-MH diagnosis. Multivariable generalized estimating equations and bivariate Rao-Scott chi-square tests were used to examine trends in ED visits and ED disposition by IPU status, adjusted for clustering by hospital., Results: From 2012 to 2016, hospitals experienced a greater increase in ED visits with a primary MH versus non-MH diagnosis (50.7% vs 12.7% cumulative increase, P < .001). MH visits were associated with patients who were older, female, white non-Hispanic, and privately insured compared with patients of non-MH visits (all P < .001). Forty-four percent of MH visits in 2016 had a primary diagnosis of depressive disorders or suicide or self-injury, and the increase in visits was highest for these diagnosis groups (depression: 109.8%; suicide or self-injury: 110.2%). Among MH visits, presence of a hospital IPU was associated with increased hospitalizations (34.6% vs 22.5%, P < .001) and less transfers (9.2% vs 16.2%, P < .001)., Conclusion: The increase in ED MH visits from 2012 to 2016 was 4 times greater than non-MH visits at US children's hospitals and was primarily driven by patients diagnosed with depressive disorders and suicide or self-injury. Our findings have implications for strategic planning in tertiary children's hospitals dealing with a rising demand for acute MH care., (Copyright © 2019 Academic Pediatric Association.

Background and Objectives: Asthma is responsible for ∼1.7 million emergency department (ED) visits annually in the United States. Studies in adults have shown that anxiety and depression are associated with increased asthma-related ED use. Our objective was to assess this association in pediatric patients with asthma., Methods: We identified patients aged 6 to 21 years with asthma in the Massachusetts All-Payer Claims Database for 2014 to 2015 using International Classification of Diseases, Ninth and 10th Revision codes. We examined the association between the presence of anxiety, depression, or comorbid anxiety and depression and the rate of asthma-related ED visits per 100 child-years using bivariate and multivariable analyses with negative binomial regression., Results: Of 65 342 patients with asthma, 24.7% had a diagnosis of anxiety, depression, or both (11.2% anxiety only, 5.8% depression only, and 7.7% both). The overall rate of asthma-related ED use was 17.1 ED visits per 100 child-years (95% confidence interval [CI]: 16.7-17.5). Controlling for age, sex, insurance type, and other chronic illness, patients with anxiety had a rate of 18.9 (95% CI: 17.0-20.8) ED visits per 100 child-years, patients with depression had a rate of 21.7 (95% CI: 18.3-25.0), and patients with both depression and anxiety had a rate of 27.6 (95% CI: 24.8-30.3). These rates were higher than those of patients who had no diagnosis of anxiety or depression (15.5 visits per 100 child-years; 95% CI: 14.5-16.4; P < .001)., Conclusions: Children with asthma and anxiety or depression alone, or comorbid anxiety and depression, have higher rates of asthma-related ED use compared with those without either diagnosis., Competing Interests: POTENTIAL CONFLICT OF INTEREST: The authors have indicated they have no potential conflicts of interest to disclose., (Copyright © 2019 by the American Academy of Pediatrics.)

Objective: This study describes the process of choosing a clinical outcome measure for a statewide performance outcome system for children receiving publicly funded mental health services in California., Methods: The recommendation is based on a five-phase approach, including an environmental scan of measures used by state mental health agencies; a statewide provider survey; a scientific literature review; a modified Delphi panel; and final rating of candidate measures by using nine minimum criteria informed by stakeholder priorities, scientific evidence, and state statute., Results: Only 10 states reported use of at least one standardized measure for outcome measurement. In California, the most frequently reported measures were the Child and Adolescent Needs and Strengths (CANS) (N=33), the Child Behavior Checklist (N=14), and the Eyberg Child Behavior Inventory (N=12). Based on modified Delphi panel ratings, only the Achenbach System of Empirically Based Assessment, the Strengths and Difficulties Questionnaire, and the Pediatric Symptom Checklist (PSC) were rated on average in the high-equivocal to high range on effective care, scientific acceptability, usability, feasibility, and overall utility. The PSC met all nine minimum criteria for recommendation for statewide use. In its final decision, the California Department of Health Care Services mandated use of the PSC and CANS., Conclusions: There is a lack of capacity to compare child clinical outcomes across states and California counties. Frequently used outcome measures were often not supported by scientific evidence or Delphi panel ratings. Policy action is needed to promote the selection of a common clinical outcome measure and measurement methodology for children receiving publicly funded mental health care.

Objectives: Our purpose in this study was to adapt and validate the Traumatic Events Screening Inventory (TESI) as a primary-care childhood adversity screening tool for children living in vulnerable neighborhoods using a community-partnered approach., Methods: In this cross-sectional, descriptive study, we used a sample of 261 children (3-16 years old) who were seeking services at a Federally Qualified Health Center with colocated behavioral health services in Chicago and had a positive Pediatric Symptom Checklist screen result or received a referral for behavioral health evaluation. The TESI was adapted as a screening tool to be sensitive to adverse childhood experiences (ACEs) unique to the clinic communities. ACEs were mapped by zip code with objective neighborhood crime data, and latent class analysis was performed to identify ACE subgroups., Results: The mapping validation suggested face validity for geographic overlap between participant ACEs and objective violent-crime occurrence. With latent class analysis, we identified 3 ACE subgroups: (1) high ACE (18.0% of the sample; polyvictimization and/or maltreatment), (2) moderate ACE (52.1%; violent environments), and (3) low ACE (29.9%; few adverse experiences). Membership in the high-ACE subgroup was associated with higher odds of a clinically significant Pediatric Symptom Checklist score (odds ratio = 3.83) and clinical-level attention problems (odds ratio = 3.58) even after accounting for child resilience and parent depression., Conclusions: ACEs play a significant role in predicting a need for behavioral health services among children seeking primary-care services. The community-adapted TESI is a valid ACE screening tool., Competing Interests: POTENTIAL CONFLICT OF INTEREST: Dr Ford is a co-owner of Advanced Trauma Solutions, Inc, which is the sole distributor of the Trauma Affect Regulation: Guide for Education and Therapy (TARGET) model (copyrighted by the University of Connecticut); the other authors have indicated they have no potential conflicts of interest to disclose., (Copyright © 2019 by the American Academy of Pediatrics.)

Purpose of Review: We review recent community interventions to promote mental health and social equity. We define community interventions as those that involve multi-sector partnerships, emphasize community members as integral to the intervention, and/or deliver services in community settings. We examine literature in seven topic areas: collaborative care, early psychosis, school-based interventions, homelessness, criminal justice, global mental health, and mental health promotion/prevention. We adapt the social-ecological model for health promotion and provide a framework for understanding the actions of community interventions., Recent Findings: There are recent examples of effective interventions in each topic area. The majority of interventions focus on individual, family/interpersonal, and program/institutional social-ecological levels, with few intervening on whole communities or involving multiple non-healthcare sectors. Findings from many studies reinforce the interplay among mental health, interpersonal relationships, and social determinants of health. There is evidence for the effectiveness of community interventions for improving mental health and some social outcomes across social-ecological levels. Studies indicate the importance of ongoing resources and training to maintain long-term outcomes, explicit attention to ethics and processes to foster equitable partnerships, and policy reform to support sustainable healthcare-community collaborations.

: media-1vid110.1542/5984243450001PEDS-VA&#95;2018-2738 Video Abstract OBJECTIVES: To improve the mental health (MH) referral process for children referred from primary care to community mental health clinics (CMHCs) by using a community-partnered approach., Methods: Our partners were a multisite federally qualified health center and 2 CMHCs in Los Angeles County. We randomly assigned 6 federally qualified health center clinics to the intervention or as a control and implemented a newly developed telehealth-enhanced referral process (video orientation to the CMHC and a live videoconference CMHC screening visit) for all MH referrals from the intervention clinics. Our primary outcome was CMHC access defined by completion of the initial access point for referral (CMHC screening visit). We used multivariate logistic and linear regression to examine intervention impact on our primary outcome. To accommodate the cluster design, we used mixed-effect regression models., Results: A total of 342 children ages 5 to 12 were enrolled; 86.5% were Latino, 61.7% were boys, and the mean age at enrollment was 8.6 years. Children using the telehealth-enabled referral process had 3 times the odds of completing the initial CMHC screening visit compared with children who were referred by using usual care procedures (80.49% vs 64.04%; adjusted odds ratio 3.02 [95% confidence interval 1.47 to 6.22]). Among children who completed the CMHC screening visit, intervention participants took 6.6 days longer to achieve it but also reported greater satisfaction with the referral system compared with controls. Once this initial access point in referral was completed, >80% of eligible intervention and control participants (174 of 213) went on to an MH visit., Conclusions: A novel telehealth-enhanced referral process developed by using a community-partnered approach improved initial access to CMHCs for children referred from primary care., Competing Interests: POTENTIAL CONFLICT OF INTEREST: The authors have indicated they have no potential conflicts of interest to disclose., (Copyright © 2019 by the American Academy of Pediatrics.)

Purpose of Review: To provide an overview of the selection process and annual updates of the child mental health measures within the Child Core Set, describe national and statewide adherence rates, and summarize findings from a systematic literature review examining measure adherence rates and whether adherence is associated with improved clinical outcomes., Recent Findings: Five national quality measures target child mental health care processes. On average, national adherence varied widely by state, and performance did not substantially improve during the past 5 years. Mean national adherence rates for the two measures related to timeliness of care were below 50%. For each measure, scientific evidence to support the association between adherence and improved clinical outcomes was scarce. Investment in academic-agency partnered research to standardize methods for publicly reporting adherence to national child mental health quality measures and validation of these measures should be a national priority for child healthcare research.

Objective: In a novel model of embedded primary care child psychiatry serving an urban Latino population, we examined determinants of successful referral and relationship between clinical need and service intensity., Methods: We conducted a chart review of referred patients from July 2013-March 2015. We used multiple logistic regressions controlling for confounders to identify determinants of successful referral. We examined the relationship between service intensity and clinical need using Poisson regression, adjusting for exposure time, age, sex, ethnicity, and language., Results: Seventy-four percent of patients completed an evaluation. Younger children (p=.0397) and those with a history of therapy (p=.0077) were more likely to make initial contact. The markers of clinical need included PSC-35 Global Scores (p=.0027) and number of psychiatric diagnoses (p=.0178) predicted number of visits., Conclusions: Our findings support early referral to improve engagement, and provide initial evidence that embedded child psychiatry consultation is feasible and may increase access to care.

Background and Objectives: Expenditures for children with noncomplex chronic diseases (NC-CDs) are related to disease chronicity and resource use. The degree to which specific conditions contribute to high health care expenditures among children with NC-CDs is unknown. We sought to describe patient characteristics, expenditures, and use patterns of children with NC-CDs with the lowest (≤80th percentile), moderate (81-95th percentile), high (96-99th percentile), and the highest (≥99th percentile) expenditures., Methods: In this retrospective cross-sectional study, we used the 2014 Truven Medicaid MarketScan Database for claims from 11 states. We included continuously enrolled children (age <18 years) with NC-CDs ( n = 1 563 233). We describe per member per year (PMPY) spending and use by each expenditure group for inpatient services, outpatient services, and the pharmacy for physical and mental health conditions. K-means clustering was used to identify expenditure types for the highest expenditure group., Results: Medicaid PMPY spending ranged from $1466 (lowest expenditures) to $57 300 (highest expenditures; P < .001); children in the highest expenditure group were diagnosed with a mental health condition twice as often (72.7% vs 34.1%). Cluster analysis was used to identify 3 distinct groups: 83% with high outpatient mental health expenditures ( n = 13 033; median PMPY $18 814), 15% with high inpatient expenditures ( n = 2386; median PMPY $92 950), and 1% with high pharmacy expenditures ( n = 213; median $325 412). Mental health conditions accounted for half of the inpatient diagnoses in the cluster analysis., Conclusions: One percent of children with the highest expenditures accounted for 20% of Medicaid expenditures in children with NC-CDs; mental health conditions account for a large proportion of aggregate Medicaid spending in children with NC-CDs., Competing Interests: POTENTIAL CONFLICT OF INTEREST: The authors have indicated they have no potential conflicts of interest to disclose., (Copyright © 2018 by the American Academy of Pediatrics.)

Importance: Retention in addiction treatment is associated with reduced mortality for individuals with opioid use disorder (OUD). Although clinical trials support use of OUD medications among youths (adolescents and young adults), data on timely receipt of buprenorphine hydrochloride, naltrexone hydrochloride, and methadone hydrochloride and its association with retention in care in real-world treatment settings are lacking., Objectives: To identify the proportion of youths who received treatment for addiction after diagnosis and to determine whether timely receipt of OUD medications is associated with retention in care., Design, Setting, and Participants: This retrospective cohort study used enrollment data and complete health insurance claims of 2.4 million youths aged 13 to 22 years from 11 states enrolled in Medicaid from January 1, 2014, to December 31, 2015. Data analysis was performed from August 1, 2017, to March 15, 2018., Exposures: Receipt of OUD medication (buprenorphine, naltrexone, or methadone) within 3 months of diagnosis of OUD compared with receipt of behavioral health services alone., Main Outcomes and Measures: Retention in care, with attrition defined as 60 days or more without any treatment-related claims., Results: Among 4837 youths diagnosed with OUD, 2752 (56.9%) were female and 3677 (76.0%) were non-Hispanic white. Median age was 20 years (interquartile range [IQR], 19-21 years). Overall, 3654 youths (75.5%) received any treatment within 3 months of diagnosis of OUD. Most youths received only behavioral health services (2515 [52.0%]), with fewer receiving OUD medications (1139 [23.5%]). Only 34 of 728 adolescents younger than 18 years (4.7%; 95% CI, 3.1%-6.2%) and 1105 of 4109 young adults age 18 years or older (26.9%; 95% CI, 25.5%-28.2%) received timely OUD medications. Median retention in care among youths who received timely buprenorphine was 123 days (IQR, 33-434 days); naltrexone, 150 days (IQR, 50-670 days); and methadone, 324 days (IQR, 115-670 days) compared with 67 days (IQR, 14-206 days) among youths who received only behavioral health services. Timely receipt of buprenorphine (adjusted hazard ratio, 0.58; 95% CI, 0.52-0.64), naltrexone (adjusted hazard ratio, 0.54; 95% CI, 0.43-0.69), and methadone (adjusted hazard ratio, 0.32; 95% CI, 0.22-0.47) were each independently associated with lower attrition from treatment compared with receipt of behavioral health services alone., Conclusions and Relevance: Timely receipt of buprenorphine, naltrexone, or methadone was associated with greater retention in care among youths with OUD compared with behavioral treatment only. Strategies to address the underuse of evidence-based medications for youths with OUD are urgently needed.
