Impact of health simulation with OSCE on the acquisition of radiotherapy competencies by RTT students

Introduction

In France, Radiation Therapist (RTT) education requires a three-year program, which includes specific training in radiotherapy. However, the limited focus on radiotherapy during initial training contributes to a shortage of RTTs. This study examines the impact of simulation-based learning and Objective Structured Clinical Examinations (OSCE) on the acquisition of essential radiotherapy competencies among third-year RTT students.

Methods

During the 2023–2024 academic year, 19 third-year RTT students participated in a study that integrated health simulation into their curriculum. The study featured five simulation stations reflecting various stages of a patient's radiotherapy journey. Students' competencies were assessed through self-evaluation questionnaires administered at three points: beginning of the year (T1), after practical workshops (PW), and post-OSCE (T3). Statistical analysis was conducted using the Friedman test and Wilcoxon signed-rank test.

Results

Significant improvements were observed across all stations, with marked progress in paramedical consultation skills, CT planning and immobilization, dosimetry, error identification, and image matching. For instance, students’ self-assessment ratings for paramedical consultation skills improved from 6 % rating themselves as “Good” or “Very good” at T1 to 94 % at T3 (p < 0.0001). Similar significant gains were noted in other stations.

Conclusion

Simulation-based learning, particularly through OSCEs, significantly enhances the acquisition of radiotherapy competencies. The approach is effective in deepening both technical skills and non-technical skills, such as clinical reasoning and communication.

Implications for Practice

Given these positive outcomes, integrating simulation-based training into the RTT curriculum should be reinforced. This strategy addresses the growing demand for highly skilled RTTs and ensures that graduates are better prepared for clinical practice in radiotherapy.
