“
I’m Jay Powers, the circulating nurse”; “I’m Zhi Xiong, the anesthesiologist”—that sort of thing. It felt kind of hokey to me, and I wondered how much difference this step could really make. But it turned out to have been carefully devised. There have been psychology studies in various fields backing up what should have been self-evident—people who don’t know one another’s names don’t work together nearly as well as those who do. And Brian Sexton, the Johns Hopkins psychologist, had done studies showing the same in operating rooms. In one, he and his research team buttonholed surgical staff members outside their operating rooms and asked them two questions: how would they rate the level of communications during the operation they had just finished and what were the names of the other staff members on the team? The researchers learned that about half the time the staff did not know one another’s names. When they did, however, the communications ratings jumped significantly. The investigators at Johns Hopkins and elsewhere had also observed that when nurses were given a chance to say their names and mention concerns at the beginning of a case, they were more likely to note problems and offer solutions. The researchers called it an “activation phenomenon.” Giving people a chance to say something at the start seemed to activate their sense of participation and responsibility and their willingness to speak up. These were limited studies and hardly definitive. But the initial results were enticing. Nothing had ever been shown to improve the ability of surgeons to broadly reduce harm to patients aside from experience and specialized training. Yet here, in three separate cities, teams had tried out these unusual checklists, and each had found a positive effect. At Johns Hopkins, researchers specifically measured their checklist’s effect on teamwork. Eleven surgeons had agreed to try it in their cases—seven general surgeons, two plastic surgeons, and two neurosurgeons. After three months, the number of team members in their operations reporting that they “functioned as a well-coordinated team” leapt from 68 percent to 92 percent. At the Kaiser hospitals in Southern California, researchers had tested their checklist for six months in thirty-five hundred operations. During that time, they found that their staff’s average rating of the teamwork climate improved from “good” to “outstanding.” Employee satisfaction rose 19 percent. The rate of OR nurse turnover—the proportion leaving their jobs each year—dropped from 23 percent to 7 percent. And the checklist appeared to have caught numerous near errors. In
