Merrill 1 1 Penn State Hershey Medical Center, Hershey, PA, USA; 2 Penn State College of Medicine, Hershey, PA, USA Introduction and Objective: In 2018, we investigated the integration of critical thinking and technical skills into the traditional residency interview process and found it feasible and provided insight into a candidate’s qualifications. Here, we explore the utility of integrating robotic simulation as an assessment metric and the use of residents as evaluators. Methods: Open suturing--OS and da Vinci ® Robotic Ring Walk 2 simulation—RS stations were incorporated into the traditional interview process. Likert scale (1-5) was used to score the candidate’s performance in each skill station and in the traditional interview (TI). The same 2 residents served as evaluators for the skill stations. Scores were analyzed with paired t-tests and anonymous candidate questionnaire responses, assessing their receptiveness, were analyzed usingWilcoxon rank sum and chi-square tests. Results: 59 candidates were interviewed. Median TI score of 4.3 (IQR 4.0, 4.6) was significantly higher than the median score for OS of 3.5 (IQR 3.0, 4.0) (p<0.001) and RS of 1.2 (0.05, 2.9) (p<0.001). For the majority of candidates, the median TI score was greater than their performance on the OS--47 (80%) as well as in the RS--51 (86%). Forty-eight (81%) of candidates scored better on OS than on RS. Forty-five (76%) candidates completed the questionnaire. Of these, 22 (49%), felt that the technical skills assessment gave them the opportunity to demonstrate capabilities not normally assessed. Nineteen (42%) of candidates felt the technical skills stations provoked more anxiety than other portion of the interview, but thirty-eight (84%) candidates thought it was less stressful having residents as evaluators. Conclusions: Using RS was a novel metric and provided better score discrimination amongst candidates, however it was perceived as being more technically challenging than OS. Utilization of residents as evaluators provided less anxiety, which is important when integrating such novel assessments into the interview process MP5-02 The Effect of 3D Printed Models on Surgical Planning and Outcomes for Partial Nephrectomies A.

Our study aimed to use simpler and less expensive 3D models to support surgical planning and operative management. Methods: Cost-effective 3D printed models ($35-50) of the affected kidney, mass, and vasculature were created using preoperative imaging of 40 patients presenting for robotic partial nephrectomies at Thomas Jefferson University Hospital (TJUH) from 6/1/2020 - 5/31/2021. Six Urologic surgeons filled out three surveys assessing their surgical plan and confidence: 1) before seeing the model, 2) after seeing the model and before surgery, and 3) after surgery. 3D modeling patients were crossmatched by Nephrometry score, demographics, operative technique, and affected kidney with patients without 3Dmodeling who had robotic partial nephrectomies at TJUH between 2018–2019. Results: Surgeons filled out both pre-operative surveys for 36 cases. Surgeon confidence significantly increased after seeing the 3D model (p = 0.016). On post-operative surveys, attendings rated the models 7.9 out of 10 in their helpfulness to anatomical comprehension. Surgeons changed their surgical plan eight times after seeing the 3D model: five times changing approach, and three times clamping selectivity. Patients with 3D modeling had a statistically higher Nephrometry score (8) compared to patients without 3D modeling (6.7) (p=0.03). Even with more complex masses, patients with 3D modeling had similar operative lengths, shorter length of stay (p=0.013), less intraoperative blood loss, less creatinine change, fewer adverse events, and a higher rate of selective clamping. Conclusions: Cost-effective 3D models are helpful tools for surgeons to understand anatomical relationships and reduce complete vascular clamping that may be difficult with imaging alone. Continued exploration is important on the benefits of 3D printing to surgeon experience to assess if these simple 3D printedmodels should become standard of care for partial nephrectomies. MP5-01 32
