Official title: Association Between Intraoperative Distractions, Surgeon Anxiety and Task Load, Team Collaboration, and Intraoperative Adverse Events: The ORCHESTRA Study
Run by National and Kapodistrian University of Athens · NCT07874412 · Data updated 2026-11-12
This study observes adults having colorectal or anal surgery to see how distractions and team dynamics relate to surgeon workload, anxiety, and intraoperative problems.

Is this trial a fit for you?
✓Likely a good fit
Adults (18+) undergoing colorectal or anal surgery at the participating unit and operated on by the designated surgeon, with consent.
✕Probably not a fit
Patients undergoing similar procedures without significant distractions or different team dynamics may see no change in outcomes.

What this trial studies
ORCHESTRA is a prospective, single-center observational cohort study conducted in an academic colorectal surgery unit. Trained observers record real-time distractions during routine operations, and after each operation the surgeon reports workload and anxiety while observers assess teamwork. Intraoperative adverse events are graded with a standard severity scale, and the study analyzes how distractions and human factors relate to these events. No treatments are assigned, and the study does not alter standard surgical care or introduce distractions.
Why it matters
Potential benefit: If distractions and team dynamics are linked to adverse events, findings could inform strategies to improve operating-room flow and reduce complications.
How similar studies have gone: Previous observational work suggests that operating-room distractions and teamwork can influence performance, but this study explores these factors in a colorectal surgery setting.
