Abstract Background Minimally invasive colorectal surgery is characterized by significant procedural variability, a difficult learning curve, and complications that affect patient outcomes. Video-based assessment offers an opportunity to generate data-driven insights to reduce variability, optimize training, and improve surgical performance. This mixed-methods study aimed to develop and validate a video-based assessment tool for workflow analysis across minimally invasive colorectal procedures. Methods An international steering committee panel of seven members coordinated a three-round modified Delphi process. Experts in colorectal surgery and video-based assessment were invited to reach consensus (≥ 70% agreement) on the phases and steps that describe workflows across colorectal surgery procedural videos. The resulting framework informed the development of ColoWorkflow. Four independent raters then applied ColoWorkflow to a multicentre video data set of laparoscopic and robotic colorectal procedures. Applicability and inter-rater reliability were evaluated. Results Of 66 invited experts, 41 (62%) from 11 countries completed round 1, 40 (98%) completed round 2, 20 attended the final online consensus meeting, and all (40 of 40) approved the final workflow descriptors. Consensus was achieved on nine procedure-agnostic phases (port placement and abdomen exploration; vascular dissection and ligation, mesocolon/mesorectum dissection, additional lymphadenectomy; colon and/or rectum mobilization; colorectal transection; anastomosis; completion of operation; preplanned additional procedures; unplanned procedures; extracorporeal procedures) and 34 procedure-specific steps that describe colorectal surgery workflows. ColoWorkflow was developed and applied to 54 colorectal surgery videos (left and right hemicolectomies, sigmoid and rectosigmoid resections, and total proctocolectomies) from five centres in four countries. The tool demonstrated broad applicability, as all phase and step labels, except one, were represented in at least one video. Inter-rater reliability was moderate, with a mean Cohen’s κ value of 0.72 for phases and 0.67 for steps. Most discrepancies arose at phase transitions and step boundary definitions. Conclusion Based on this preliminary work, ColoWorkflow is a promising tool for workflow analysis across minimally invasive colorectal procedures. Its adoption may help standardize training, accelerate competency acquisition, and advance data-informed surgical quality improvement.

Abstract In 2001, The American Association of Immunologists Committee on the Status of Women conducted a survey examining the percentage of women faculty members within immunology departments or women in immunology graduate programs across 27 institutions in the United States, comparing it to the percentage of women receiving a Ph.D. Here, we examine the representation of women across these same 27 immunology departments and programs to examine changes in gender equity over the last 15 years.
