Growing empirical support exists to guide the development of assessment and intervention related to PMTS for patients with pediatric illness and their parents. The need for interventions across the course of pediatric illness and injury that target patients, families, and/or healthcare teams is apparent. The model provides a basis for further development of evidence-based treatments.

National Center for Child Traumatic Stress Children and adolescents who are exposed to traumatic events are helped by numerous child-serving agencies, including health, mental health, education, child welfare, first responder, and criminal justice systems to assist them in their recovery. Service providers need to incorporate a trauma-informed perspective in their practices to enhance the quality of care for these children. This includes making sure that children and adolescents are screened for trauma exposure; that service providers use evidenceinformed practices; that resources on trauma are available to providers, survivors, and their families; and that there is a continuity of care across service systems. This article reviews how traumatic stress impacts children and adolescents' daily functioning and how various service systems approach trauma services differently. It also provides recommendations for how to make each of these service systems more trauma informed and an appendix detailing resources in the National Child Traumatic Stress Network that have been produced to meet this objective.

Based on new evidence, the renamed Integrative Trajectory Model includes phases corresponding with medical events, adds family-centered trajectories, reaffirms a competency-based framework, and suggests updated assessment and intervention implications.

Traumatic stress symptoms are common among parents in the PICU and may persist long after discharge. There is strong support from these data for continued attention to supporting parents both during and after a child's PICU admission.
