Development of virtual radiology clinical competency evaluation amidst COVID-19 at a dental school

To describe and report on the use of virtual clinical competency examinations (VCCEs) for D3 dental students in a radiology clinic during the COVID-19 pandemic and relate the technology to other clinical and educational applications.

Paper-based clinical competency examinations (CCEs) were converted to three different VCCEs to closely replicate the CCEs. Existing grading rubrics were used to assess students' abilities to evaluate technical issues and interpret intraoral full-mouth series and panoramic radiographs. The grading rubrics were modified from their clinical versions to eliminate non-reproducible skills, such as patient management and application of selection criteria. Radiographs were selected from clinic records and anonymized. VCCEs were conducted via WebEx conferences that were scheduled via an appointment app. These experiences can be extended to virtual patient contacts, teleradiology, and telemedicine, as well as continuing dental education experiences.

Approximately 200 VCCEs were administered by four oral and maxillofacial radiology faculty over a 10-week period. Both students and faculty managed the technology well, with few missed appointments. All students were successful in challenging the examinations and appeared to be satisfied with the experience.

Although direct comparisons between the CCEs and the new VCCEs are difficult, as there was no time to pilot the VCCEs, students were successful in challenging the examinations and informally reported satisfaction with the experience. Although components of CCEs that could not be replicated on the VCEs could not be assessed, it is felt that the students had adequate experience in selection of radiographs and patient management prior to the COVID-19 lockdown. Additional benefits of the VCCEs included contact with students to check on their well-being. The experience indicates that VCCEs can be used in the future in hybrid models of oral & maxillofacial radiology education, clinical care, patient screening, and telemedicine. Moreover, the success of this demonstration points to potential for personalized distance learning in continuing dental education.
