文摘

Image-guided radiation therapy (IGRT) through daily cone-beam computed tomography (CBCT) has significantly impacted the role of the radiation therapist at our institution; continuing education is crucial to ensure safe practice of technology in the clinical environment. The purpose of this work was to develop and implement an electronic learning (eLearning) module as a yearly refresher for CBCT-practicing radiation therapists.

Methods

To provide an innovative interface to engage the learner's interest, a module themed “Myths in Cone Beam Computed Tomography Practice” was developed by content experts at our institution. The eLearning tool focused on the technical aspects and fundamental theory of CBCT acquisition, with an aim to refresh the user's knowledge and confidence in image fusion and assessment. Ten myths were identified in the module and evidence-based content was referenced within each myth to support theory. Evaluation of the learner was performed through a multiple choice quiz at the end of the module. The tool and 12 multiple choice questions were reviewed and validated by subject matter and non–subject matter experts in CBCT–IGRT before departmental implementation.

Results

The CBCT eLearning module has been clinically implemented and used over the last 3 years by radiation therapists in our department. Completion of the tool is an annual mandatory requirement for CBCT-practicing therapists; over 100 participants completed the module per year. The median time for module completion decreased over the 3-year interval, from 42 minutes 25 seconds during the first year of implementation to 20 minutes and 48 seconds in the third year.

Conclusions

An electronic online training tool for CBCT refresher training has been developed and implemented at our institution, with an aim to equip staff with the critical thinking skills and clinical judgment required to operate in a CBCT–IGRT environment. The module's format ensures delivery of consistent information as a component of yearly continuing education for radiation therapists.
