Video Assessment—Nontechnical skills
Video recordings of assessments were analyzed independently by 2 assessors who were not involved in the iVR training and were blinded to the participant group. One assessor was a senior hip arthroplasty fellow with over 10 years of postgraduate experience, the other was an orthopedic surgery trainee with 4 years of postgraduate experience. Both had specific training using 3 nontechnical skills scores: (1) Non-Operative Technical Skills for Surgeons (NOTSS) (primary outcome measure), (2) the Oxford NOn-TECHnical Skills II (NOTECHS-II) score, and (3) the Scrub Practitioners’ List of Intraoperative Non-Technical Skills (SPLINTS) score. All 3 scores have been validated and have been demonstrated to be reliable and reproducible.
