An integrated network
It is simply unrealistic to expect that any single program of intervention or research could ever help us to reach such a big outcome, like timely and accurate diagnosis for all children with ASD. My previous work has outlined how research is simply one element of a roadmap to better outcomes. Research must be part of an integrated network that includes training, policy, and increasingly advocacy. All of these elements only influence outcomes through their impact on services and supports delivered to people with ASD, or their caregivers. Ideally, these services take the form of evidence-based practices, delivered by individual, trained professionals, often working together as part of a program.
But this complex network break down easily and frequently. My detailed case study of a young man in behavioral crisis illustrates the many ways that can happen, with life-changing consequences for people living with ASD, and at tremendous cost to society. Some of these breakdowns are entirely avoidable given the evidence-based practices already available. For more than 20 years, I have sought to try to identify how to prevent such breakdowns, by translating research on diagnosis and treatment into specific programs in schools, hospitals, and universities. And for most of that time, I was directly accountable for the breakdowns that did occur, because I was directly delivering education and treatment, or because I was leading programs that delivered such services.
Multiple sectorsHome CommunityPhysical/Mental/Behavioral HealthPublic/Higher educationMultiple levelsLocal RegionalState NationalWe need clear roadmaps to navigate these complex inter-relationships. These relationships often span not just multiple elements (services, training, research, and policy), but often multiple sectors (health, education, and community services), and multiple levels (local, regional, state, and national). Several years ago, I tried to bring these complex relationships together in the design of a statewide autism training network. This network was carefully positioned to generate recommendations across agencies responsible for services, training, and policy, to gather data about progress directly from stakeholders, to pilot new programs of training, and to report directly to the state legislature.
Consider how a successful program of ASD screening must cut across disciplines, sectors, and agencies within a multi-level network. Screening can occur in community-based settings (like schools or pediatric clinics), but may require a specialist clinic at a regional hospital to complete the diagnostic assessment, or a policy decision at the state level that ensures that screenings will be properly reimbursed. Perhaps each of these decisions is spurred by a recommendation at the national level to conduct universal ASD screening, delivered by a panel of experts from a professional practice organization like the American Academy of Pediatrics.
I first tried to navigate such a network with respect to ASD screening more than 20 years ago, when I developed and delivered a program to try to train pediatricians across Montreal to use the CHAT. Later, I designed a web-based roadmap that was specifically intended to help parents and professionals navigate the system of services by drawing on the expertise of a statewide Act Early team, with the ultimately goal of gathering data on service gaps that would shape a statewide plan. These and other lessons learned were integrated into my 2013 review. This review concluded with a recommendation that we begin by constructing roadmaps that focus on a subset of specific, pivotal outcomes, like improved identification of ASD through early screening and diagnosis.
Understanding the complementary roles of individual professionals and agencies within the network
Every element within this roadmap seeks different outcomes and adopts different definitions of progress. In the case of ASD screening, a researcher pursuing a specific line of inquiry might define progress in term of increased understanding of the early indicators of ASD. A professional implementing a specific practice with a particular student, patient, or client might define progress in terms of access to a new screening tool. A leader promoting the adoption of a large-scale screening program might define progress in terms of improved access for an entire population of people with ASD. Ideally, we hope that these differences converge in the big, overarching goal for our science that our society adopts.
Such a roadmap can help to define these very specific, often complementary, and inter-related roles of individuals within different agencies and sectors, at different levels of the network. Consider the example of ASD screening undertaken by a community-based pediatrician. A pediatrician who reads an article about a promising new screening tool usually cannot just begin to successfully implement the practice through the services they deliver themselves. They must often collaborate with others in a program of services (e.g., they consider the results of the ASD screening with the results of other screening tools completed by nurse practitioner before making a specific referral). Sometimes the practice requires coordination with professionals in another program (e.g., screening might only be considered appropriate if another program is able to provide more specialized diagnostic evaluations as needed). Sometimes the practice is enhanced by statewide training offered through a university-based program. Several programs I have helped to develop and implement focused on early identification sought to capitalize on the complementary roles of different professionals (like an initiative to train nurse practitioners to effectively diagnose ASD in less complex cases) and agencies (like an initiative to train community-based clinics outside of urban regions to reliably diagnose ASD in less complex cases).
One of the biggest challenges is the fact that many professionals have limited, meaningful experience in other sectors, or focused on multiple elements. For example, many professionals spend most or all of their professional career in one kind of agency (in a hospital or a school or a university or in government) focused on one element (services or training or research or policy). This becomes more challenging as research seeks to evolve beyond the laboratory to address training and services, or to reach beyond the university to include school and community resources, or beyond the local level to reach state or federal policymakers. Even when adopting specific strategies like collective impact that take advantage of the strengths of each partner, professionals trying to work across elements or sectors are much less likely to understand the opportunities or challenges faced by their collaborators.
And many professionals have limited experience in leading programs, especially through significant periods of growth and change. Even under the best of conditions, developing and implementing large scale change is a challenge without strong and experienced leadership. Problem leaders will struggle to achieve simple expansion or improvements in services, let alone true innovation.
As a result, trying to promote an emerging practice across different sectors, elements, or levels is like running a relay race of undetermined length and difficulty, with unidentified runners who are partially blindfolded and trying to hand off a greased baton (Doehring, 2013). But with a roadmap that clearly defines the elements of the network and how they interact, we can begin to recruit our runners and train for our race.
