A combined problem-based and simulation-based learning model significantly strengthens radiology staff preparedness for managing iodinated contrast media allergic emergencies.
A new study highlights the usefulness of an integrated problem-based learning (PBL) and simulation-based learning (SBL) training model in strengthening the ability of radiology staff to respond to iodinated contrast media (ICM) allergic responses—a potentially life-threatening complication during imaging procedures.
Researchers conducted a sequential exploratory mixed-methods study in 2024 to assess whether combining PBL and SBL could improve emergency preparedness among radiology personnel. Initially, qualitative insights were gathered through semi-structured interviews with 9 radiology staff members. These interviews were examined using Colaizzi’s phenomenological method to guide the development of a context-specific PBL-SBL training framework.'
Subsequently, a randomized controlled trial was conducted involving 60 radiology professionals, including physicians, technologists, and nurses. Participants were randomly assigned to:
Emergency performance (primary outcome) was assessed through structured simulation exercises, while secondary outcomes included critical thinking ability measured by the critical thinking disposition inventory-chinese version (CTDI-CV) scale and participant satisfaction with the training. The PBL-SBL training group demonstrated significantly superior performance compared with the control group in key emergency management domains, including procedural response, medication administration, and team coordination (Z = −6.544 to −6.667).
Participants exposed to the integrated training also showed notably higher scores across all dimensions of critical thinking (Z = −5.660 to −6.654). They also reported greater satisfaction with the learning approach, improved teamwork dynamics, stronger self-directed learning capacity, enhanced learning quality, and increased interest in training (Z = −2.149 to −5.161).
Hence, integrating PBL with SBL instruction substantially strengthened both the clinical preparedness and cognitive competencies of radiology staff in responding to ICM allergic reactions. Compared with traditional lecture-based training, the hybrid educational model fostered stronger teamwork, critical thinking, and engagement among participants.
