Eye-Tracking Biomarkers and Autism Diagnosis in Primary Care.

Importance: Finding effective and scalable solutions to address diagnostic delays and disparities in autism is a public health imperative. Approaches that integrate eye-tracking biomarkers into tiered community-based models of autism evaluation hold promise for addressing this problem. Objective: To determine whether a battery of eye-tracking biomarkers can reliably differentiate young children with and without autism in a community-referred sample collected during clinical evaluation in the primary care setting and to evaluate whether combining eye-tracking biomarkers with primary care practitioner (PCP) diagnosis and diagnostic certainty is associated with diagnostic outcome. Design, Setting, and Participants: Early Autism Evaluation (EAE) Hub system PCPs referred a consecutive sample of children to this prospective diagnostic study for blinded eye-tracking index test and follow-up expert evaluation from June 7, 2019, to September 23, 2022. Participants included 146 children (aged 14-48 months) consecutively referred by 7 EAE Hubs. Of 154 children enrolled, 146 provided usable data for at least 1 eye-tracking measure. Main Outcomes and Measures: The primary outcomes were sensitivity and specificity of a composite eye-tracking (ie, index) test, which was a consolidated measure based on significant eye-tracking indices, compared with reference standard expert clinical autism diagnosis. Secondary outcome measures were sensitivity and specificity of an integrated approach using an index test and PCP diagnosis and certainty. Results: Among 146 children (mean [SD] age, 2.6 [0.6] years; 104 [71%] male; 21 [14%] Hispanic or Latine and 96 [66%] non-Latine White; 102 [70%] with a reference standard autism diagnosis), 113 (77%) had concordant autism outcomes between the index (composite biomarker) and reference outcomes, with 77.5% sensitivity (95% CI, 68.4%-84.5%) and 77.3% specificity (95% CI, 63.0%-87.2%). When index diagnosis was based on the combination of a composite biomarker, PCP diagnosis, and diagnostic certainty, outcomes were concordant with reference standard for 114 of 127 cases (90%) with a sensitivity of 90.7% (95% CI, 83.3%-95.0%) and a specificity of 86.7% (95% CI, 70.3%-94.7%). Conclusions and Relevance: In this prospective diagnostic study, a composite eye-tracking biomarker was associated with a best-estimate clinical diagnosis of autism, and an integrated diagnostic model including PCP diagnosis and diagnostic certainty demonstrated improved sensitivity and specificity. These findings suggest that equipping PCPs with a multimethod diagnostic approach has the potential to substantially improve access to timely, accurate diagnosis in local communities.

Leveraging Public Health and Public School Partnerships for Local Surveillance of Positive Childhood Experiences.

Childhood psychosocial experiences can have a lifelong effect on health. These experiences can be measured together as positive and adverse childhood experiences or individually as positive childhood experiences (PCEs) or adverse childhood experiences. Most research on PCEs has focused on how PCEs promote health outcomes. However, limited research has been conducted on the prevalence of PCEs among adolescents in local areas served by public health departments. The St. Joseph County Department of Health developed a study to test the feasibility of surveillance of PCEs through local public health departments and to establish a prevalence for PCE exposure among a population of urban public-school students in Indiana. We conducted a survey in spring 2022 that collected demographic information on students at 2 high schools and 1 middle school and assessed exposure to PCEs. We assessed prevalence of PCEs on a 5-point Likert scale (0 = never, 1 = rarely, 2 = sometimes, 3 = usually, 4 = always). PCE scores were grouped into low (0-2), medium (3-5), and high (6 or 7). The prevalence of individual PCE items ranged from 35.6% to 86.8%. Among 798 respondents, 189 (23.7%) reported low PCE scores, 396 (49.6%) reported medium scores, and 213 (26.7%) reported high scores. This research demonstrates the feasibility of school-based PCE surveillance and establishes a baseline prevalence of PCE exposure among a population of middle and high school students. These methods are applicable to different contexts and can provide both local health departments and school systems with a new tool to address adverse childhood experiences.

Diagnostic Accuracy of Primary Care Clinicians Across a Statewide System of Autism Evaluation.

OBJECTIVES: To evaluate the diagnostic accuracy of the Early Autism Evaluation (EAE) Hub system, a statewide network that provides specialized training and collaborative support to community primary care providers in the diagnosis of young children at risk for autism spectrum disorder (ASD). METHODS: EAE Hub clinicians referred children, aged 14 to 48 months, to this prospective diagnostic study for blinded follow-up expert evaluation including assessment of developmental level, adaptive behavior, and ASD symptom severity. The primary outcome was agreement on categorical ASD diagnosis between EAE Hub clinician (index diagnosis) and ASD expert (reference standard). RESULTS: Among 126 children (mean age: 2.6 years; 77% male; 14% Latinx; 66% non-Latinx white), 82% (n = 103) had consistent ASD outcomes between the index and reference evaluation. Sensitivity was 81.5%, specificity was 82.4%, positive predictive value was 92.6%, and negative predictive value was 62.2%. There was no difference in accuracy by EAE Hub clinician or site. Across measures of development, there were significant differences between true positive and false negative (FN) cases (all Ps < .001; Cohen's d = 1.1-1.4), with true positive cases evidencing greater impairment. CONCLUSIONS: Community-based primary care clinicians who receive specialty training can make accurate ASD diagnoses in most cases. Diagnostic disagreements were predominately FN cases in which EAE Hub clinicians had difficulty differentiating ASD and global developmental delay. FN cases were associated with a differential diagnostic and phenotypic profile. This research has significant implications for the development of future population health solutions that address ASD diagnostic delays.

Tele-assessment of young children referred for autism spectrum disorder evaluation during COVID-19: Associations among clinical characteristics and diagnostic outcome.

LAY ABSTRACT: The diagnosis of autism spectrum disorder (ASD) has traditionally been made through in-person evaluation. While the COVID-19 pandemic disrupted access to ASD services, there has been remarkable growth in research focused on novel ASD diagnostic practices, including the use of telemedicine. We implemented a standard ASD tele-assessment evaluation procedure, including use of a novel remote clinician-coached, caregiver-delivered ASD assessment tool (TELE-ASD-PEDS; TAP), with the goal of continuing to provide diagnostic services to young children and their families during the pandemic. We examined the relationship between child characteristics and diagnostic outcome for 335 children, ages 14-78 months, who received ASD tele-assessment conducted by psychologists and pediatricians in an outpatient clinic of a Midwestern academic medical center. We found that clinicians could make a determination about ASD diagnosis for most children (85%) evaluated using tele-assessment. Child clinical characteristics, including TAP scores and clinician ratings of ASD symptoms, were related to diagnostic outcome (i.e. diagnosis of ASD, no ASD, and Unsure about ASD). When all clinical characteristics were examined together, the presence of specific repetitive behaviors predicted ASD diagnosis. We also found that the TAP is effective for making an ASD diagnosis when used as part of comprehensive tele-assessment evaluation in children ⩾ 36 months of age with delayed language. Our study adds to an increasing body of research supporting use of tele-assessment for diagnosis of ASD. Although further research is needed, telemedicine may help families from different backgrounds and geographic locations to access high-quality diagnostic services.

Acceptability and Access Metrics for Telehealth Consultation of Pediatric Neurodevelopmental Disabilities During COVID-19.

INTRODUCTION: We report caregiver agreement to attend telehealth neurodevelopmental consultation during COVID-19, demographic differences in agreement, reasons families declined, and clinical access metrics before and during COVID-19. METHOD: Data were gathered from telehealth referrals and consultations from April to July 2020. Schedulers documented agreement status and reasons for the decline. Wait time, lag time, and missed appointment rates were calculated to measure access. RESULTS: Ninety-one percent agreed to attend telehealth consultation; 55% of those who declined preferred in-person services. There were no demographic differences between those who accepted, declined, or did not respond. The median wait time from referral to appointment was 60 days. Missed appointment rates were consistent with prepandemic rates. DISCUSSION: Findings support literature suggesting patients are agreeable to telehealth. They diverged from evidence suggesting telehealth reduces missed appointments. Overall, results indicate telehealth is an acceptable alternative; however, further telehealth innovation is needed to address existing disparities.

Telehealth Evaluation of Pediatric Neurodevelopmental Disabilities During the COVID-19 Pandemic: Clinician and Caregiver Perspectives.

OBJECTIVE: The objective of this study was to present clinician and caregiver perspectives regarding telehealth neurodevelopmental evaluation delivered at the onset of the coronavirus disease 2019 (COVID-19) pandemic. Specifically, we sought to describe telehealth neurodevelopmental evaluations, examine associations between child characteristics and diagnostic factors, determine the impact of technology and family barriers, and report on clinician and caregiver satisfaction with telehealth evaluation. METHODS: In response to the COVID-19 pandemic, in-person clinical services at a large children's hospital neurodevelopmental clinic were transitioned to telehealth. Data are presented for 254 remote evaluations of children (18-212 months; referral concern: 51% autism spectrum disorder [ASD], 24% developmental delay/intellectual disability, 25% other neurodevelopmental concern) conducted from May to July 2020. Data were gathered from electronic health records as well as clinician and caregiver surveys. RESULTS: A clinical diagnosis was provided in 72% of telehealth evaluations. Clinicians rated diagnostic certainty as "completely" or "somewhat" certain in 74% of evaluations. Certainty ratings were higher for evaluations in which a diagnosis of ASD was provided. Although technology and family challenges were reported, clinicians rarely identified these as disruptive to the evaluation process. Clinicians reported satisfaction with various aspects of delivering telehealth. Caregivers endorsed high satisfaction with receipt of telehealth and reduced travel burden. CONCLUSION: The COVID-19 pandemic has rapidly transformed service delivery for individuals with neurodevelopmental disabilities and provided an unprecedented opportunity to evaluate the deployment of telehealth evaluation to meet the need for ongoing diagnostic care. Our findings suggest that telehealth holds significant promise for neurodevelopmental assessment both within the context of a global pandemic and beyond.

INteractive Virtual Expert-Led Skills Training: A Multi-Modal Curriculum for Medical Trainees.

Background: Internationally, pediatric depression and suicide are significant issues. Additionally, in the context of the COVID-19 pandemic, pediatric mental health needs are rising astronomically. In light of Child & Adolescent Psychiatrist (CAP) subspecialist shortages in the United States (US), there is an increasing call for primary care physicians in Family Medicine and Pediatrics to address an increasingly broad variety of patient needs. Here we report on the development and preliminary evaluation of medical student and resident perceptions on the "INteractive Virtual Expert-led Skills Training" (INVEST) medical education curriculum, a virtual synchronous CAP curriculum employing active learning strategies, including expert-led discussion and video modeling, and discussion designed to meet those priorities. Methods: In a standardized 60-min training format, our curriculum leverages audience response system polling, video modeling of key clinical skills, and interactive discussion with an expert subspecialist, over a virtual video conferencing platform. The primary educational strategy relies on use of video modeling to demonstrate best practice with CAP led group discussion to solidify and explain important concepts. Five waves of medical students and residents (N = 149) participated in the INVEST curriculum and completed pre- and post-training surveys regarding knowledge and comfort in the management of pediatric patients with depression and suicidality. Results: Trainee participants reported significant positive gains in perceived likelihood of encountering pediatric suicidality as well as knowledge/comfort with depression screening and suicidality assessment in a primary care setting. Across some competency areas, there was an effect of medical learner level. Learners at lower levels generally reported the highest benefit. Medical students reported significant increases in their comfort interpreting and discussing positive depression screens and evidenced the greatest relative benefit in comfort with discussing suicidality. Conclusion: To our knowledge, INVEST is the first fully virtual, multimodal curriculum led by expert CAP subspecialists. Our findings suggest that INVEST shows promise for equipping medical learners with baseline knowledge for caring for patients with pediatric depression and suicidality. This synchronous, virtually delivered curriculum allows for critical training delivered to diverse medical learners regardless of geographic location, a particular benefit during the current COVID-19 pandemic.

Family-Centered Care Coordination in an Interdisciplinary Neurodevelopmental Evaluation Clinic: Outcomes From Care Coordinator and Caregiver Reports.

Children with neurodevelopmental disabilities experience many unmet healthcare needs. Care coordination is one critical solution to addressing the substantial strain on families, local communities, and the larger healthcare system. The purpose of this study was to implement a care coordination program in an interdisciplinary pediatric neurodevelopmental evaluation clinic and examine care coordinator and caregiver outcomes. Following neurodevelopmental diagnosis, children were provided with either care coordination (CC) or care as usual (CAU). For those receiving CC, the care coordinator documented family goals and care coordination activities, outcomes, and time spent. Caregivers in both groups completed a survey measuring access to needed services and caregiver stress and empowerment following their child's evaluation (T1) and 4-6 months post-evaluation (T2). Care coordinator findings demonstrated that over 85% of family goals focused on understanding the child's diagnosis, getting needed interventions and educational support, and accessing healthcare financing programs. More than half of care coordination activities were spent on engaging and educating the family; similarly, the most time-consuming care coordination efforts were in helping families understand their child's diagnosis and meeting family's basic needs. For those children referred to needed services, 54% were enrolled in one or more service at T2. Caregivers in both the CC and CAU groups reported an increase in stress related to interactions with their child as well as increased empowerment from T1 to T2. Contrary to our hypotheses, there were no significant group-by-time interactions across caregiver-report measures. While these findings further our understanding of care coordination delivery, they diverge from previous evidence demonstrating care coordination efficacy. This study paves the way for future opportunities to evaluate what kinds of care coordination supports family need at varying times in their child's healthcare journey and how the outcomes important to all stakeholders are measured to reflect true evaluation of efficacy.

Addressing Academic Concerns: A Survey of Primary Care Providers.

Given new clinical recommendations, we sought to better understand the perspectives and practices of primary care providers (PCPs) around pediatric academic concerns. Practicing PCPs were recruited to complete an 8-item self-report survey; 163 PCPs were included in the final analysis. Results indicated that 84% of PCPs perceived their role in addressing patients' academic concerns as highly important; yet there was variability in the frequency with which PCPs reported engaging in activities around these educational needs. There was a significant positive relationship between perception of role importance and engagement in clinical supports. Some differences were present in responses across PCP specialty area. More information about practice differences between provider types, rural versus urban practices, and how perceptions/practices differ based on provider demographics are likely to be useful areas for future consideration. Our findings highlight the need to advance PCP instruction for practical implementation to increase rates of engagement in these activities.

Specific Learning Disabilities: The Family Physician's Role.

Academic underachievement, such as failing a class and the threat of being held back because of academic issues, is common. Family physicians can provide support and guidance for families as they approach their child's unique academic challenges. Specific learning disabilities are a group of learning disorders (e.g., dyscalculia, dysgraphia, dyslexia) that impede a child's ability to learn. Understanding standard educational terms; looking for medical, family, and social risk factors associated with academic underachievement; and investigating the medical differential for academic underachievement can help direct the family to appropriate care. The physician can provide medical documentation to support an individualized education program evaluation and address risk factors that schools may not be aware of or cannot assess. The family physician can support children and families by understanding the connection between risk factors, medical and educational evaluations, and educational resources.
