Introduction: Surgical experience requires skills traditionally taught through real-time operating room education and a variety of supplemental educational strategies. Video-based coaching is a modality that may offer potential advantages of immediate, direct and targeted feedback. The objective of this study was to demonstrate and evaluate the utility and educational value of videobased coaching in urology by conducting a qualitative analysis with a coding schema.Methods: Residents and attendings were recorded operating during randomly selected cases in the operating room. Video-based coaching sessions were held during urology grand rounds and required residents to describe a selected portion of the operating room video and attendings to provide teaching points. Audio recordings from the operating room and video-based coaching sessions were reviewed by 2 independent coders. A coding scale classifying surgical educational goals into 5 categories (information, operative technique, questioning, response to resident interaction and unrelated commenting) was used to identify the interactions and was adjusted for time.Results: Four urological cases were selected for recording. In the video-based coaching sessions compared to the operating room, attendings made more teaching points per hour, provided more information to residents (mean teaching points 7.7 for video-based coaching vs 2.9 for operating room, p <0.005), emphasized operative skills and technique (mean teaching points 10.5 for videobased coaching vs 4.1 for operating room, p <0.005), and were more likely to ask open-ended discussion leading questions (mean teaching points 28.5 for video-based coaching vs 4.4 for operating room, p <0.05).Conclusions: Video-based coaching delivered in short time frames offers an easily implementable additional learning opportunity for resident education to further enhance skills learned in the urological operating room.

Background: Targeted magnetic resonance (MR) with ultrasound (US) fusion-guided biopsy has been shown to improve detection of prostate cancer. The implementation of this approach requires integration of skills from radiologists and urologists. Objective methods for assessment of learning curves, such as cumulative sum (CUSUM) analysis, may be helpful in identifying the presence and duration of a learning curve. The aim of this study is to determine the learning curve for MR/US fusion-guided biopsy in detecting clinically significant prostate cancer using CUSUM analysis. Materials and methods: Retrospective analysis was performed in this institutional review board-approved study. Two urologists implemented an MR/US fusion-guided prostate biopsy program between March 2015 and September 2017. The primary outcome measure was cancer detection rate (CDR) stratified by Prostate Imaging Reporting and Data System (PI-RADS) scores assigned on the MR imaging. Cumulative sum analysis quantified actual cancer detection versus a predetermined target satisfactory CDR of MR/US fusion biopsies in a sequential case-by-case basis. For this analysis, satisfactory performance was defined as >80% CDR in patients with PI-RADS 5, >50% in PI-RADS 4, and <20% in PI-RADS 1-3. Results: Complete data were available for MR/US fusion-guided biopsies performed on 107 patients. The CUSUM learning curve analysis demonstrated intermittent underperformance until approximately 50 cases. After this inflection point, there was consistently good performance, evidence that no further learning curve was being encountered. Conclusions: At a new center implementing MR/US fusion-guided prostate biopsy, the learning curve was approximately 50 cases before a consistently high performance for prostate cancer detection.
