There is growing concern about the shortage of well-trained pediatric and behavioral health professionals prepared to deliver effective, evidence-based care to children and their families. This shortage is especially evident in the care and support of military children with mental, emotional, developmental, and/or behavioral health (MEDB) conditions. Importantly, telehealth, tele-education, and telementoring can provide opportunities to expand and support the cadre of professionals with the knowledge and skills to deliver such care. However, this is complicated by a lack of evidence-based strategies for delivering these activities. The DoD Child Collaboration Study aims to address this gap through the development, expansion, and evaluation of best practices for telehealth to reduce disparities in access for vulnerable and high-risk children, adolescents, and young adults with MEDB needs receiving care within the Military Health System. Led by the Uniformed Services University’s (USU) Center for Deployment Psychology (CDP) and Kennedy Krieger Institute, the DoD Child Collaboration Study supports efforts to explore and expand the use of telehealth and tele-education strategies by connecting civilian experts in pediatric neurodevelopmental and/or behavioral healthcare with frontline Tricare-authorized healthcare providers (i.e., pediatricians, family medicine providers, behavioral health providers) in civilian communities accessed by military children and Military Treatment Facilities. A cornerstone of this project is to increase the utilization of telehealth services to bring specialized care to highly mobile families wherever they are located. However, we recognize that access to care will not adequately address this need if these providers have not received training and support to care for military children with complex MEDB conditions. Implementing Project ECHO® case consultation and telementoring, and developing asynchronous training opportunities will build provider capacity to deliver evidence-based, culturally competent treatments. Additionally, creating evidence-based digital tools will increase provider and caregiver access to high-quality digitized assessment and treatment modules relevant to military children with MEDB needs. Finally, stakeholder networks will be utilized to ensure the feasibility and applicability of the program. Through additional partnerships with the USU Departments of Pediatrics and Family Medicine, the University of Minnesota, and Georgetown University and continued partnership with Kennedy Krieger Institute, CDP will also coordinate a broad research effort to identify programs and service delivery models to enhance the care and well-being of children with MEDB needs by leveraging advances in telehealth and technology. This research “collaboratory” will include a repository of information and resources that identify innovative and effective methods to increase access to care and support using technology, provide recommendations for evaluating technologies for efficacy, and collect data and information from the lived experiences of military families and professionals working directly with military children and families. We further intend for this research collaboratory to provide communication, connection, coordination, and collaboration opportunities to support military kids and families. Program evaluation will be conducted, as appropriate, to evaluate the effect of the various project activities. This multi-pronged study aims to increase providers’ and caregivers’ access to quality care, information, and resources and ultimately help improve the care and support of military children with MEDB needs.
