We aim to evaluate remote MR training compared to in-person (IP) training using a validated US-guided percutaneous renal access hydrogel simulation model. METHODS: 12 residents with <5 cases were randomized into 2 groups. Anatomy and US-guided percutaneous access (PCA) steps were reviewed by trainees prior to completing a (1) pre-test, (2) training session (either MR or IP), (3) mid-test, (4) crossover training and (5) final post-test. Groups were randomized to MR vs IP training first where faculty guided trainees through PCA on a standard hydrogel model. During MR training faculty guided trainees wearing SMART glasses (Vuzix M4000) that transmitted audio and the merged surgical field (Figure 1a). In all 3 tests trainees independently gained needle access, guidewire passage and serial dilatation of the lower and upper pole. Number of attempts, time and 2 reviewers’ scores of each session using a validated grading tool were collected. Post-training surveys evaluated trainee perceptions. RESULTS: On the pre-test, IP group had a higher average score compared to the MR group (55 vs 38, p=0.02) and less average access attempts (5.4 vs 10.5, p<0.05) with comparable times (484 s vs 401, p=0.18). Comparing pre to mid tests, MR vs IP showed a greater improvement in PCA attempts by 22.9% vs 7.4% (p=0.13), time by 19.5% vs 17.9% (p=0.39) and score by 65% vs 25% (p=0.04). After cross-over training, only MR group improved in PCA attempts (14.9%), time (17%) and score (7%). Comparing pre to post-tests the MR 1st vs IP 1st group showed a greater improvement in PCA time (24% vs 14%, p=0.23) and score (39% vs 16%, p=0.03) (Figure 1b). 66.7% of trainees found MR training to be similar to IP regarding usefulness, clarity, accuracy, timeliness and quantity but only 8.3% preferring MR to IP. Participants reported similar confidence in ability to perform simulated US-guided renal access. CONCLUSIONS: Remote training using MR technology provided comparable learning to IP simulation training. Despite the improved performance and equivalent delivery when using MR technology, trainee perceptions towards remote training remain skeptical.
