Given the increasing emphasis on care coordination between healthcare and schools, hospital–school liaison services are increasing in demand. Limited research examines hospital–school liaison programs that focus on educational journeys of school-age patients with a chronic illness. Thus, this initiative aimed to determine the time needed to support the educational needs of these patients. Liaisons tracked time spent per patient, and per specific task category, to support school-age patients (N = 419) using work-sampling and time-and-motion methods. Findings may be useful for hospital-based programs seeking to establish or increase staff dedicated to the coordination of care between school and healthcare systems.
