Hospitalized children experience pain as part of their condition, diagnostics and treatment, which has consistently been reported as poorly assessed and undertreated [1, 2].  Exposure to undertreated pain is associated with adverse outcomes that impact children, their families, health services, and communities [3]. Engaging children and families in care can improve care quality and safety. Patient portals integrated with hospital electronic medical/health records [EMR/EHR] can improve child and family engagement, outcomes and satisfaction during hospitalization [4]. However, existing studies have not considered the unique focus of hospital-based portals in pediatric pain care. As part of a broader research program, the perspectives of primary caregivers (PCGs) of hospitalized children and hospitalized youth about their potential role using an inpatient portal to support their engagement in pain care during hospitalization were explored.
