<p>Structured opportunities for interprofessional education remain limited in radiation oncology training programs, particularly related to emergency scenarios. To address this gap, we developed a workshop entitled "ONC-Call: A Team-Based Response to Spinal Cord Compression" at The University of Texas MD Anderson Cancer Center. The three-hour workshop took place on July 18, 2025, and involved 53 participants, including 10 radiation oncology residents, 7 medical physics residents, 21 radiation therapy students, and 15 medical dosimetry students. Participants rotated through five interactive stations—patient evaluation, patient simulation, treatment planning, physics quality assurance, and treatment delivery—each led by an instructor from the corresponding discipline. The patient simulation and treatment delivery stations took place at a CT simulator and treatment machine, respectively, which were engaged with mannequins to facilitate hands-on education. Participants completed Likert-scale questionnaires before and after the workshop, including an Interprofessional Attitudes Scale (IPAS) for all participants and a clinical confidence survey for the radiation oncology residents. Response rates were 79% and 75% for the pre- and post-workshop IPAS questionnaires, respectively, and 100% and 80% for the pre- and post-workshop radiation oncology resident-specific surveys, respectively. The baseline IPAS questionnaire responses reflected strongly favorable attitudes across all healthcare domains without any significant differences between pre- and post-workshop responses. However, radiation oncology residents demonstrated significant improvements in 13 out of 14 clinical confidence items following the workshop. This reproducible session may be adapted by other institutions to enhance interprofessional preparedness in radiation oncology emergencies.</p>
