Feasibility and acceptability of the “Day 100 Talk”: An interdisciplinary communication intervention during the first six months of childhood cancer treatment

Background: Communication gaps arise early in the childhood cancer trajectory and may persist. The authors conducted a pilot study of the feasibility and acceptability of a communication intervention, the Day 100 Talk (D100). D100 involves an interprofessional family conference during initial months of treatment between oncologists, psychosocial clinicians, and parents, facilitated by a 3-part conversation tool. Methods: The authors enrolled English-speaking parents of children with nonrelapsed, nonprogressive cancer who were receiving continuity care from enrolled pediatric oncologists and psychosocial clinicians at a single site. The a priori feasibility threshold was 60% parent completion of the D100 intervention. Surveys from parents and professionals and debrief interviews with professionals assessed D100 acceptability. Results: Thirty-seven parents (77%) and 38 oncology professionals (67%) enrolled. Twenty of 33 evaluable parents (61%) participated in a D100 family conference. Most commonly, parents did not complete the D100 intervention because of scheduling difficulties related to clinical team constraints. All 17 parents who completed a post-D100 survey agreed or strongly agreed that D100 participation was helpful. In debrief interviews, professionals identified D100 benefits, namely, stepping back to the big picture and getting on the same page, and barriers related to logistical challenges and professionals' anticipatory dread. Conclusions: The D100 intervention pilot demonstrates high acceptability among parents of children with cancer. Despite meeting the prespecified feasibility threshold, findings highlight important barriers to D100 dissemination, namely, perceived burdens on professionals. Potential strategies to reduce burden may include using virtual visit platforms, incorporating D100 elements across multiple visits, or prioritizing intervention delivery to parents with the greatest need for enhanced communication.
