Moving from research to practice in the primary care of children with autism spectrum disorders

Health Care for Autistic Children: A Public Health Perspective

Autism has been the subject of large-scale public health investment. These investments are increasingly shifting toward mitigating the lifelong disability and impairment associated with autism. Key efforts include bolstering screening schedules, accelerating the path to diagnosis and early entry into evidence-based therapies, and providing preventive management of common co-occurring conditions. Enhancing their implementation will necessitate addressing neurodiversity and health equity. Pediatric primary care teams continue to be important stewards in population-level initiatives to promote autistic health. To thrive in this role, these providers will benefit from specific educational and logistical supports from the health care system.

Age of autism diagnosis in Latin American and Caribbean countries

LAY ABSTRACT

An earlier diagnosis of autism spectrum disorder might lead to earlier intervention. However, people living in Latin American and Caribbean countries do not have much knowledge about autism spectrum disorder symptoms. It has been suggested that the older a child is when diagnosed, the fewer opportunities he or she will have to receive services. We asked 2520 caregivers of autistic children in six different Latin America and Caribbean Countries, the child's age when they noticed some developmental delays and their child's age when they received their first autism spectrum disorder diagnosis. Results indicate that, on average, caregivers were concerned about their child's development by 22 months of age; however, the diagnosis was received when the child was 46 months of age. In addition, older children with better language abilities and public health coverage (opposed to private health coverage) were diagnosed later. On the contrary, children with other medical problems and more severe behaviors received an earlier diagnosis. In our study, children were diagnosed around the time they entered formal schooling, delaying the access to early intervention programs. In summary, the characteristics of the autistic person and the type of health coverage influence the age of diagnosis in children living in Latin America and Caribbean Countries.

Identifying Components of Autism Friendly Health Care: An Exploratory Study Using a Modified Delphi Method

OBJECTIVES

Autistic individuals report lower health care satisfaction. However, there is currently no set of "best practice" standards about caring for autistic individuals. In this exploratory study, we aim to identify features of Autism Friendly practice according to a sample consisting of mainly professionals whose interests include autism using a modified 3-round Delphi-a method that identifies a consensus view across subject participants.

METHODS

Statements about components of an Autism Friendly health care practice were compiled in consultation with the steering committee of an Autism Friendly Initiative at a single, urban academic safety-net hospital. Participants were recruited through our national network of professionals and patients/families mailing list. Examples of invited professionals included researchers, health care workers, and educators. In the first 2 rounds, we distributed electronic surveys to participants, who scored statements from 1 to 9 regarding importance. In round 2, statements that were scored low by all stakeholder groups were eliminated. Seventy-eight participants responded to the first-round survey, and 51 participants responded to the second-round survey. In the third round, 38 participants ranked 16 statements from most to least important. Statements are summarized and presented in the Results section.

RESULTS

Topics that emerged from highly ranked statements include environmental/operational modifications (e.g., longer appointment times) and staff training to support autistic patients.

CONCLUSION

Highly ranked statements represented previously reported barriers, including the need for staff training and inclusive engagement with the autistic community. The findings can help inform health care organizations to determine priorities when building an Autism Friendly health care practice.

Screening for autism spectrum disorder in deaf adults with intellectual disability: Feasibility and accuracy of two autism screening instruments

BACKGROUND

There is a lack of autism screening instruments for deaf or hard of hearing (DHH) adults with intellectual disability.

AIMS

This study examined the diagnostic validity of the Pervasive Developmental Disorder in Mental Retardation Scale and the Diagnostic Behavioral Assessment for autism spectrum disorder - Revised in this rare population.

METHODS AND PARTICIPANTS

56 DHH adults with intellectual disability living in three specialized therapeutic communities were examined, 9 of whom met criteria for autism.

OUTCOMES AND RESULTS

With minimal adaptions regarding item interpretation, both tools showed good diagnostic and high convergent validity. Items probing for difficulties in reciprocal social interaction and restricted interests were discriminant between individuals with and without autism.

CONCLUSION

These data suggest that both autism screening tools are feasible and psychometrically sound when used with appropriate adaptations for DHH adults with intellectual disability.

Age of diagnosis, service access, and rights of autistic individuals in Argentina: Caregivers reports of changes and similarities across time

BACKGROUND

Many countries have developed health initiatives to protect those with disabilities and developmental concerns in the past few years. However, the needs of autistic individuals are still short of being fulfilled. Partially due to limited research expenditure, which would allow bridging the gap between evidence and practice, the long time it takes to implement passed laws, and the limited operationalization of inclusive policies.

OBJECTIVE

To quantitatively examine changes in the child's age at the time of caregiver's first developmental concerns and age of diagnosis of their autistic child across 5 years. Also, to address challenges experienced by caregivers (e.g., reported service barriers) and the work still needing to be done in Argentina based on caregivers' reports of their priorities (e.g., ensuring their child receives better services).

METHODS

Two independent samples of caregivers of autistic individuals were surveyed by the Red Espectro Autista Latinoamerica (REAL) in 2015 (n = 763) and the World Health Organization (WHO) in 2020 (n = 422). Similar items in both surveys were compared through descriptive inferential analysis and chi-square tests for categorical variables.

RESULTS

Compared to the 2015 sample, for the 2020 sample, more caregivers reported an earlier age of first concerns and an earlier age of a professional diagnosis. In the 2020 sample, more children diagnosed before the age of three had a doctor or a teacher noticing the first developmental concern. Also, in this sample, fewer caregivers reported service barriers (e.g., limited availability, waitlist, costs, etc.) and a need for better social support and better health services. However, rates of caregivers indicating a need for more rights for autistic individuals and greater protection of existing rights increased. There was no change in the reported rate of family members who stopped working to care for the autistic individual. For both samples, there was statistically significant differences in individual (physician, teacher, caregiver) noticing first developmental concern and the age of diagnosis, with the majority having a caregiver noticing the first concern.

CONCLUSION

The 5 years that separate both samples show an improvement in developmental concerns being noticed, a decrease in age of diagnosis, and an improvement in several service areas such as community awareness. Also, caregivers reported fewer barriers to service accessibility, thus suggesting a positive impact stemming from changes in public policies, non-profit organizations' work through awareness campaigns, and advocates' strives toward greater awareness. Nonetheless, a similar proportion of family members reported ceasing working to care for autistic individuals and perceived that the fundamental rights of their autistic children needed to be protected. These results imply that despite better care pathways in Argentina, there are still gaps when attempting to meet the needs of autistic individuals and their families. The present study provides a meaningful understanding of existing gaps and help exemplify the perceived improvements when non-profit agencies and advocates promote increased rights and community awareness in addition to the established laws focusing on ASD.

Rethinking autism spectrum disorder assessment for children during COVID-19 and beyond

The COVID-19 pandemic has posed unique challenges for families and caregivers, as well as for autism-focused clinicians, who are faced with providing a thorough and accurate evaluation of children's specific needs and diagnoses in the absence of in-person assessment tools. The shift to telehealth assessments has challenged clinicians to reconsider approaches and assumptions that underlie the diagnostic assessment process, and to adopt new ways of individualizing standard assessments according to family and child needs. Mandates for physical distancing have uncovered deficiencies in diagnostic practices for suspected autism and have illuminated biases that have posed obstacles preventing children and families from receiving the services that they truly need. This Commentary outlines several considerations for improving diagnostic practices as we move forward from the current pandemic and continue to strive to build an adaptable, sustainable, equitable, and family-centered system of care. LAY SUMMARY: Physical distancing and the abrupt end to in-person services for many children on the autism spectrum has forced clinicians to examine the existing challenges with autism spectrum disorder (ASD) diagnostic assessment and consider things they want to keep and things that should be changed in the years ahead. New approaches such as telehealth both alleviated and exacerbated existing disparities, and brought into stark focus the importance of equitable and timely access to family-centered care. This commentary suggests ways of improving clinical practices related to ASD assessment to continue along this path.

Practitioner's review: medication for children and adolescents with autism spectrum disorder (ASD) and comorbid conditions

Alleviating the multiple problems of children with autism spectrum disorder (ASD) and its comorbid conditions presents major challenges for the affected children, parents, and therapists. Because of a complex psychopathology, structured therapy and parent training are not always sufficient, especially for those patients with intellectual disability (ID) and multiple comorbidities. Moreover, structured therapy is not available for a large number of patients, and pharmacological support is often needed, especially in those children with additional attention deficit/hyperactivity and oppositional defiant, conduct, and sleep disorders.

Effectiveness of the Extension for Community Health Outcomes Model as Applied to Primary Care for Autism: A Partial Stepped-Wedge Randomized Clinical Trial

IMPORTANCE

The Extension for Community Health Outcomes (ECHO) model is a widely adopted technology-based model for training primary care physicians and practitioners (PCPs) to care for patients with complex conditions. Despite its popularity, to our knowledge, direct effects of ECHO on clinical practice have not been tested in a large-scale study.

OBJECTIVE

To test the effectiveness of the ECHO model as applied to primary care for autism and whether it resulted in improved clinical practice, knowledge, and self-efficacy regarding autism screening and comorbidity management.

DESIGN, SETTING, AND PARTICIPANTS

Primary care physicians and practitioners were recruited to participate in a 6-month ECHO Autism program delivered by 1 of 10 academic medical center sites. A sequential, staggered rollout of ECHO Autism was delivered to 5 cohorts of participants (15 per site; 2 sites per cohort). Sites were randomized after recruitment to cohort/start time. Cohorts launched every 3 months. The ECHO Autism program used videoconferencing technology to connect community-based PCPs with interdisciplinary expert teams at academic medical centers. There were 148 participants (PCPs [family practice physicians, pediatricians, nurse practitioners, and physician assistants] providing outpatient services to underserved children) studied between December 2016 and November 2018.

INTERVENTIONS

The 6-month ECHO Autism program included twelve 2-hour sessions connecting PCP participants with an interdisciplinary expert team. Sessions included didactics, case-based learning, guided practice, and discussion.

MAIN OUTCOMES AND MEASURES

Coprimary outcomes were autism screening practices and comorbidity management (assessed by medical record review). Secondary outcomes were knowledge (assessed by direct testing) and self-efficacy (assessed by self-report survey). Assessments were conducted at baseline, mid-ECHO, post-ECHO, and follow-up (3 months after ECHO).

RESULTS

Ten sites were randomized to 1 of 5 cohorts. Participants were 82% female (n = 108), 76% white (n = 100), and 6% Hispanic or Latino (n = 8); the median age was 46 years (interquartile range, 37-55 years). Significant changes in autism screening and treatment of comorbidities in children with autism were not observed. Participants demonstrated significant improvements in knowledge (9%; 95% CI, 4-13; P < .001) and self-efficacy (29%; 95% CI, 25-32; P < .001).

CONCLUSIONS AND RELEVANCE

The ECHO model was developed to increase access to high-quality health care for underserved patients with complex conditions. Study results provide support for the model in improving clinician knowledge and confidence but little support for achieving practice change.

Linking the Medical and Educational Home to Support Children With Autism Spectrum Disorder: Practice Recommendations

Children with autism spectrum disorder (ASD) present with complex medical problems that are often exacerbated by a range of other intellectual and psychiatric comorbidities. These children receive care for their physical and mental health from a range of providers within numerous child-serving systems, including their primary care clinic, school, and the home and community. Given the longitudinal nature in which care is provided for this chronic disorder, it is particularly necessary for services and providers to coordinate their care to ensure optimal efficiency and effectiveness. There are 2 primary venues that serve as a "home" for coordination of service provision for children with ASD and their families-the "medical home" and the "educational home." Unfortunately, these venues often function independently from the other. Furthermore, there are limited guidelines demonstrating methods through which pediatricians and other primary care providers (PCPs) can coordinate care with schools and school-based providers. The purpose of this article is 2-fold: (1) we highlight the provision of evidence-based care within the medical home and educational home and (2) we offer practice recommendations for PCPs in integrating these systems to optimally address the complex medical, intellectual, and psychiatric symptomology affected by autism.

Understanding Neurodevelopmental Disorders: The Promise of Regulatory Variation in the 3'UTRome

Neurodevelopmental disorders have a strong genetic component, but despite widespread efforts, the specific genetic factors underlying these disorders remain undefined for a large proportion of affected individuals. Given the accessibility of exome sequencing, this problem has thus far been addressed from a protein-centric standpoint; however, protein-coding regions only make up ∼1% to 2% of the human genome. With the advent of whole genome sequencing we are in the midst of a paradigm shift as it is now possible to interrogate the entire sequence of the human genome (coding and noncoding) to fill in the missing heritability of complex disorders. These new technologies bring new challenges, as the number of noncoding variants identified per individual can be overwhelming, making it prudent to focus on noncoding regions of known function, for which the effects of variation can be predicted and directly tested to assess pathogenicity. The 3'UTRome is a region of the noncoding genome that perfectly fulfills these criteria and is of high interest when searching for pathogenic variation related to complex neurodevelopmental disorders. Herein, we review the regulatory roles of the 3'UTRome as binding sites for microRNAs or RNA binding proteins, or during alternative polyadenylation. We detail existing evidence that these regions contribute to neurodevelopmental disorders and outline strategies for identification and validation of novel putatively pathogenic variation in these regions. This evidence suggests that studying the 3'UTRome will lead to the identification of new risk factors, new candidate disease genes, and a better understanding of the molecular mechanisms contributing to neurodevelopmental disorders.

General practice encounters for young patients with autism spectrum disorder in Australia

This study compared the patient demographics and reasons for encounter in general practice for patients <25 years with and without an autism spectrum disorder identified as a reason for encounter and/or problem managed. The Bettering the Evaluation and Care of Health programme collected information about clinical activities in Australian general practice. Each year, the programme recruited a random sample of 1000 general practitioners, each of whom collected data for 100 consecutive consultations (encounters). Encounters with patients <25 years, where at least one autism spectrum disorder was recorded as a reason for encounter and/or a problem managed (n = 579), were compared with all other encounters (n = 281,473) from April 2000 to March 2014 inclusive. Data were age–sex standardised. Patients at autism spectrum disorder encounters (compared to non-autism spectrum disorder encounters) were more likely to be younger and male. There was a dramatic rise in the number of general practitioner consultations at autism spectrum disorder encounters from 2000 to 2013. More reasons for encounter were recorded at autism spectrum disorder encounters than at non-autism spectrum disorder encounters (156.4 (95% confidence interval: 144.0–168.8) and 140.5 (95% confidence interval: 140.0–141.0), respectively). At autism spectrum disorder (vs non-autism spectrum disorder) encounters, there were more psychological, general and unspecified, and social reasons for encounter and fewer preventive and acute health reasons for encounter. People with an autism spectrum disorder have complex health care needs that require a skilled general practice workforce.

ECHO Autism

Children with autism spectrum disorder (ASD) have complex medical problems, yet they are at high risk for unmet health care needs. Primary care providers are perfectly positioned to meet these needs; however, they often lack training in ASD. This pilot project developed and tested a new model for training primary care providers in best-practice care for ASD using the Extension for Community Healthcare Outcomes (ECHO) framework. The 6-month ECHO Autism pilot project consisted of 12 biweekly clinics focused on screening and identification of ASD symptoms and management of medical and psychiatric comorbidities. Participants completed measures of practice behavior and self-efficacy in screening and management of children with ASD at baseline (pretest) and after 6 months of ECHO Autism (posttest). Statistically significant improvements were observed in self-efficacy, in adherence to ASD screening guidelines, and in use of ASD-specific resources. Participants also reported high satisfaction with the program.

Examining cross-cultural differences in autism spectrum disorder: A multinational comparison from Greece, Italy, Japan, Poland, and the United States

Autism spectrum disorder (ASD) is characterized by social and communication impairments as well as restricted, repetitive behavior patterns. Despite the fact that ASD is reported worldwide, very little research exists examining ASD characteristics on a multinational scale. Cross-cultural comparisons are especially important for ASD, since cultural differences may impact the perception of symptoms. Identifying behaviors that are similarly reported as problematic across cultures as well as identifying behaviors in which there is cultural variation could aid in the development and refinement of more universally effective measures. The present study sought to examine similarities and differences in caregiver endorsement of symptom severity through scores on the Baby Infant Screen for Children with aUtIsm Traits (BISCUIT). The BISCUIT was utilized to examine ASD core symptomology in 250 toddlers diagnosed with ASD from Greece, Italy, Japan, Poland, and the United States. Significant differences in overall ASD symptom severity and endorsement were found between multinational groups. Implications of the results are discussed.

Integrating care for neurodevelopmental disorders by unpacking control: A grounded theory study

BACKGROUND

To establish integrated healthcare pathways for patients with neurodevelopmental disorders (ND) such as autism spectrum disorder and attention-deficit hyperactivity disorder is challenging. This study sets out to investigate the main concerns for healthcare professionals when integrating ND care pathways and how they resolve these concerns.

METHODS

Using classic grounded theory (Glaser), we analysed efforts to improve and integrate an ND care pathway for children and youth in a Swedish region over a period of 6 years. Data from 42 individual interviews with a range of ND professionals, nine group interviews with healthcare teams, participant observation, a 2-day dialogue conference, focus group meetings, regional media coverage, and reports from other Swedish regional ND projects were analysed.

RESULTS

The main concern for participants was to deal with overwhelming ND complexity by unpacking control, which is control over strategies to define patients' status and needs. Unpacking control is key to the professionals' strivings to expand constructive life space for patients, to squeeze health care to reach available care goals, to promote professional ideologies, and to uphold workplace integrity. Control-seeking behaviour in relation to ND unpacking is ubiquitous and complicates integration of ND care pathways.

CONCLUSIONS

The Unpacking control theory expands central aspects of professions theory and may help to improve ND care development.

Autism spectrum disorder traits in Slc9a9 knock-out mice

Autism spectrum disorders (ASDs) are a group of neurodevelopmental disorders which begin in childhood and persist into adulthood. They cause lifelong impairments and are associated with substantial burdens to patients, families, and society. Genetic studies have implicated the sodium/proton exchanger (NHE) nine gene, Slc9a9, to ASDs and attention-deficit/hyperactivity disorder(ADHD). Slc9a9 encodes, NHE9, a membrane protein of the late recycling endosomes. The recycling endosome plays an important role in synapse development and plasticity by regulating the trafficking of membrane neurotransmitter receptors and transporters. Here we tested the hypothesis that Slc9a9 knock-out (KO) mice would show ADHD-like and ASD-like traits. Ultrasonic vocalization (USV) recording showed that Slc9a9 KO mice emitted fewer calls and had shorter call durations, which suggest communication impairment. Slc9a9 KO mice lacked a preference for social novelty, but did not show deficits in social approach; Slc9a9 KO mice spent more time self-grooming, an indicator for restricted and repetitive behavior. We did not observe hyperactivity or other behavior impairments which are commonly comorbid with ASDs in human, such as anxiety-like behavior. Our study is the first animal behavior study that links Slc9a9 to ASDs. By eliminatingNHE9 activity, it provides strong evidence that lack of Slc9a9leads to ASD-like behaviors in mice and provides the field with a new mouse model of ASDs.

Parental Perceptions of Family Centered Care in Medical Homes of Children with Neurodevelopmental Disabilities

Life course theory sets the framework for strong inclusion of family centered care (FCC) in quality medical homes of children with neurodevelopmental disabilities (CNDD). The purpose of this study was to explore the perceptions of families with their experiences of FCC in medical homes for CNDD. Using a structured questionnaire, the Family-Centered Care Self-Assessment Tool developed by Family Voices, this study surveyed 122 parents of CNDD in a large urban area during 2010-2012. Data collected information on FCC in the provision of primary health care services for CNDD and focused on family-provider partnerships, care setting practices and policies, and community services. Frequency analysis classified participants' responses as strengths in the "most of the time" range, and weaknesses in the "never" range. Only 31 % of parents were satisfied with the primary health care their CNDD received. Based on an accepted definition of medical home services, 16 % of parents reported their CNDD had most aspects of a medical home, 64 % had some, and 20 % had none. Strengths in FCC were primarily evident in the family-provider partnership and care settings when focused on meeting the medical care needs of the child. Weaknesses in FCC were noted in meeting the needs of families, coordination, follow-up, and support with community resources. Improvements in key pediatric health care strategies for CNDD are recommended. CNDD and their families have multifaceted needs that require strong partnerships among parents, providers, and communities. Quality medical homes must include FCC and valued partnerships with diverse families and community-based providers.

Translating Research to Practice for Children With Autism Spectrum Disorder: Part 2: Behavior Management in Home and Health Care Settings

INTRODUCTION

Managing home and health care for children with autism spectrum disorder can be challenging because of the range of symptoms and behaviors exhibited.

METHOD

This article presents an overview of the emerging science related to the methods to foster family self-management of common concerns regarding activities of daily living and behaviors, as well as for the health care provider in primary and acute health care settings.

RESULTS

Recommendations are provided to enhance the overall delivery of services, including understanding and managing a child's challenging behaviors, and supporting family management of common activities of daily living and behaviors.

DISCUSSION

Health care providers' knowledge of evidence-based recommendations for providing care, supporting family self-management of common concerns, and referral heighten the likelihood of better outcomes for children with autism spectrum disorder.

Diagnosing autism: Australian paediatric research network surveys

AIM

Autism spectrum disorder (ASD) is a neurodevelopmental disorder with reported prevalence of more than 1/100. In Australia, paediatricians are often involved in diagnosing ASD and providing long-term management. However, it is not known how paediatricians diagnose ASD. This study aimed to investigate whether the way Australian paediatricians diagnose ASD is in line with current recommendations.

METHODS

Members of the Australian Paediatric Research Network were invited to answer questions about their ASD diagnostic practice in a multi-topic survey and also as part of a study about parents needs around the time of a diagnosis of ASD.

RESULTS

The majority of the 124 paediatricians who responded to the multi-topic survey and most who responded to the parent needs survey reported taking more than one session to make a diagnosis of ASD. Most paediatricians included information from preschool, child care or school when making a diagnosis, and over half included information from speech pathology or psychology colleagues more than 50% of the time. The main reasons for not including assessment information in the diagnostic process were service barriers such as no regular service available or long waiting lists. More than 70% reported ordering audiology and genetic tests more than half of the time.

CONCLUSION

Not all paediatricians are following current recommendations for diagnosing ASD more than 50% of the time. While there are good reasons why current diagnostic approaches may fall short of expected standards, these need to be overcome to ensure diagnostic validity and optimal services for all children and their families.

A Comparison of Ambulatory Care Sensitive Hospitalizations Among Children With and Without Autism Spectrum Disorder

OBJECTIVE

To compare the prevalence of hospitalizations for ambulatory care sensitive conditions (ACSC) in children with and without autism spectrum disorder (ASD) and to compare inpatient health care utilization (total charges and length of stay) for the same conditions in children with and without ASD.

METHODS

The 2009 Kids' Inpatient Database was used to examine hospitalizations for ACSC in children within 3 cohorts: those with ASD, those with chronic conditions (CC) without ASD, and those with no CC.

RESULTS

The proportion of hospitalizations for ACSC in the ASD cohort was 55.9%, compared with 28.2% in the CC cohort and 22.9% in the no-CC cohort (P < .001). Hospitalized children with ASD were more likely to be admitted for a mental health condition, epilepsy, constipation, pneumonia, dehydration, vaccine-preventable diseases, underweight, and nutritional deficiencies compared with the no-CC cohort. Compared with the CC cohort, the ASD cohort was more likely to be admitted for mental health conditions, epilepsy, constipation, dehydration, and underweight. Hospitalized children with ASD admitted for mental health conditions had significantly higher total charges and longer LOS compared with the other 2 cohorts.

CONCLUSIONS

The proportion of potentially preventable hospitalizations is higher in hospitalized children with ASD compared with children without ASD. These data underscore the need to improve outpatient care of children with ASD, especially in the areas of mental health care and seizure management. Future research should focus on understanding the reasons for increased inpatient health care utilization in children with ASD admitted for mental health conditions.

Autism Spectrum Disorder: Defining Dimensions and Subgroups

Autism spectrum disorder (ASD) is a behaviorally defined neurodevelopmental disorder associated with the presence of social-communication deficits and restricted and repetitive behaviors. In the latest conceptualization of ASD, these two behavioral dimensions represent the core defining features of ASD, whereas associated dimensions, such as intellectual and language ability, provide a means for describing the ASD heterogeneity. In addition, the characterization of ASD subgroups, defined by the presence of known medical, genetic, or other psychiatric disorders, furthers our understanding of ASD heterogeneity. This paper reviews the history of autism, describes its core defining features, and provides an overview of the clinically and etiologically relevant subgroups that add to the complexity of this condition.
