I’m going to have to start yelling!” Later, he slammed his headlamp to the floor and stormed out of the operating room. His team, which hadn’t yet finished the surgical procedure, was left stunned.

Her observations—which, all told, logged the nature of 6348 interactions during 200 operations—uncovered a surprising source of conflict in operating rooms: the
