Building Bricks of Integrated Care Pathway for Autism Spectrum Disorder: A Systematic Review

A new model for the diagnostic assessment services trajectory for neurodevelopmental conditions

Purpose

The Canadian province of Québec faces several issues regarding the accessibility and quality of diagnostic assessment and the efficiency and continuity of evaluation, support, and intervention services for children with neurodevelopmental conditions (NDCs). To address these issues, the Ministry of Health and Social Services mandated a research team to initiate the development of a reference trajectory, i.e., a proposed model pathway based on national and international best practices and research, for the diagnostic assessment of NDCs in children aged 0-7 years.

Methods

The present study focused on the development of a logic model to operationalize the diagnostic services trajectory using a community-based participatory research approach and informed by implementation science. This involved representatives from multiple stakeholder groups (e.g., parents, professionals, physicians, administrators, researchers). Project steps included an analysis of best practices from a literature review on diagnostic trajectories, focus groups and interviews with stakeholders, and a validation process to ensure the appropriateness of the final model.

Results

The integration of existing research and stakeholder input resulted in a logic model for a new diagnostic services trajectory for children aged 0-7 years suspected of NDCs and identified key ingredients that should be present in its future implementation.

Conclusion

The proposed model for a diagnostic services trajectory is expected to address several systemic issues identified previously. Its implementation will need to be evaluated to ensure its sustained focus on the needs of families and its ability to promote their quality of life, well-being, and involvement.

Decoding the genetic landscape of autism: A comprehensive review

BACKGROUND

Autism spectrum disorder (ASD) is a complex neurodevelopmental condition characterized by heterogeneous symptoms and genetic underpinnings. Recent advancements in genetic and epigenetic research have provided insights into the intricate mechanisms contributing to ASD, influencing both diagnosis and therapeutic strategies.

AIM

To explore the genetic architecture of ASD, elucidate mechanistic insights into genetic mutations, and examine gene-environment interactions.

METHODS

A comprehensive systematic review was conducted, integrating findings from studies on genetic variations, epigenetic mechanisms (such as DNA methylation and histone modifications), and emerging technologies [including Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-Cas9 and single-cell RNA sequencing]. Relevant articles were identified through systematic searches of databases such as PubMed and Google Scholar.

RESULTS

Genetic studies have identified numerous risk genes and mutations associated with ASD, yet many cases remain unexplained by known factors, suggesting undiscovered genetic components. Mechanistic insights into how these genetic mutations impact neural development and brain connectivity are still evolving. Epigenetic modifications, particularly DNA methylation and non-coding RNAs, also play significant roles in ASD pathogenesis. Emerging technologies like CRISPR-Cas9 and advanced bioinformatics are advancing our understanding by enabling precise genetic editing and analysis of complex genomic data.

CONCLUSION

Continued research into the genetic and epigenetic underpinnings of ASD is crucial for developing personalized and effective treatments. Collaborative efforts integrating multidisciplinary expertise and international collaborations are essential to address the complexity of ASD and translate genetic discoveries into clinical practice. Addressing unresolved questions and ethical considerations surrounding genetic research will pave the way for improved diagnostic tools and targeted therapies, ultimately enhancing outcomes for individuals affected by ASD.

An innovative and collaborative method to develop a model care and service trajectory for the assessment, diagnosis, and support of children with developmental disabilities

This paper documents an innovative research approach undertaken to co-develop an integrated assessment, diagnosis, and support service trajectory for children suspected of having a developmental disability. It employed data-driven practices and involved multiple stakeholders such as parents, professionals, managers, and researchers. It emphasized the importance of incorporating experiential knowledge adopting an integrated care and service trajectory perspective, and using an implementation science framework. The first part of this article presents the theoretical roots and the collaborative method used to co-construct the model trajectory. The second part of this article presents the results of a survey in which participating stakeholders shared their point of view on the value and impact of this approach Overall, this article provides a step-by-step operationalization of participative research in the context of public health and social services. This may help guide future initiatives to improve services for developmental disabilities in partnership with those directly concerned by these services.

A Window into the Use of Post-diagnostic Services for Autism and Parents' Perspective on the Quality of Early Childhood Services Trajectory in a Canadian Province

The pathway for post-diagnostic services for autism tends to be complex, heterogeneous, and fraught with delays. This situation has repercussions for families' experience with care systems, the quality of early interventions, and family adjustment. To date, studies of parents' point of view on autism services have predominantly focused on the diagnostic phase of the services trajectory. The goal of the present study was to investigate the perspective of parents on autism early childhood services within a public healthcare and social services system in a Canadian province (Québec). Participants were 91 parents who completed a structured framework for the evaluation of the quality of services trajectories, the Evaluation of the services Trajectory in Autism by Parents (ETAP; Mello et al., in Research in Developmental Disabilities 133, 2023). Approximately three-quarters of families received interim services (e.g., punctual speech therapy interventions) for which they had overall neutral-to-positive appraisals but viewed as having comparably low validity and continuity. Although all children diagnosed with autism are entitled to receive early behavioral intervention (EBI) dispensed by the public health and social services system, approximately a quarter of families did not receive this service. Families who received EBI evaluated this service positively on all ETAP dimensions. The empathy (i.e., parent-provider relationships) dimension was rated highest for both interim and EBI services. Some systemic, family, and child-related factors were associated with the perceived quality of services for both interim and early childhood services. Our results emphasize the need for services for children and families as soon as possible, both during assessment and after diagnosis.

Updates in the care of youths with intellectual disability and autism spectrum disorder

PURPOSE OF REVIEW

Since the turn of the new millennium, care for people with intellectual disability/intellectual developmental disorders (IDD) and/or autism spectrum disorder (ASD) has drawn increasing attention because of the continuous prevalence increase of these two conditions, the high health vulnerability, especially mental vulnerability, and the crucial role of care provision in the setting of continued deinstitutionalization and the shift to community care. The present review addresses the main issues related to mental healthcare in youth with IDD and/or ASD with a specific focus on adolescence and transition to adulthood.

RECENT FINDINGS

Despite the existence of specific recommendations, persons with IDD/ASD lack access to quality mental healthcare within communities, receive inadequate diagnosis and intervention, including medication overuse as well as ineffective residential, educational, employment, financial, and social support services. The lack of a unified care system that provides services across all domains and life ages may be the cause of users' perceptions and experiences of inefficiencies.

SUMMARY

The scientific community seems to converge on that care should be provided in accordance with principles of interdisciplinarity, life-span view, precision, personalization, and participation. Quality of life appears to be an ideal conceptual reference for care planning and outcome evaluation.
