Telementoring for Identifying the Appendix Using Telesonography

The 30 participating examiners were randomly divided into two groups. In phase one, group A performed ultrasonography under onsite mentoring and group B performed the same procedure under remote mentoring. Each examiner was randomly assigned one expert and three SPs for phase one. Four weeks later, they were partnered with the same expert and SPs to whom they had been assigned in phase one and performed the procedure under the other type of mentoring (phase two). The examination order of the SPs was randomly assigned by choosing a number between one and six (1: A-B-C, 2: A-C-B, 3: B-A-C, 4: B-C-A, 5: C-A-B, 6: C-B-A) in each phase.
