In aviation, there is a reason the “pilot not flying” starts the checklist, someone pointed out. The “pilot flying” can be distracted by flight tasks and liable to skip a checklist. Moreover, dispersing the responsibility sends the message that everyone—not just the captain—is responsible for the overall well-being of the flight and should have the power to question the process. If a surgery checklist was to make a difference, my colleagues argued, it needed to do likewise—to spread responsibility and the power to question. So we had the circulating nurse call the start.
