The book discusses the use of checklists, both in the author’s domain of surgery, and in other domains such as aircraft piloting and construction management. It makes and documents claims about the ability of checklists to significantly, and sometimes radically, reduce errors and increase success rates.
I see three main lessons in the book, one obvious, and the other two less obvious.
The Obvious Lesson
The first and obvious lesson is that checklists can serve as a powerful tool for buttressing unaided human cognition. Even experts are prone to forgetting or overlooking steps in task, and using checklists can make a massive difference in the quality and valence of a task’s outcome.
But on the other hand, as example after example in the book showed, the items on the checklists that are making such a difference are obvious. For example, in the pilot’s checklist for what to do during “Engine Failure,” the second item – in large print – is “Fly the airplane.” Similarly, in checklists used in hospital, checklist items are things like “Confirm that the patient has verified his identity,” and “Confirm that all team members have introduced themselves by name and role.” Checklists are not being used to keep track of complicated things, or hard to remember things, or things that their users don’t know well.
The Important and Easily-missed Lessons
Instead, checklists are being used to ensure a group is working together in an effective way. Checklists are being used as scaffolding to support group processes, not so much individual cognition. This brings us to the second and third lessons I took from the book (lessons which I do not think were emphasized nearly enough): checklists are used as part of a shared, social practice rather than as a solitary tool.
The second lesson is that going through a checklist was a group activity, and it is this collective activity that leads the group to reflect on and prepare for the group’s task; it also facilitated (“activated”) later communication within the group and appears to have increased group affinity and commitment. This effect is explicitly invoked in checklists that highlight communicative activities (“the submittal schedule” — who should talk with whom about what and by when) rather than instrumental activities.
The third lesson is that when a checklist is adopted as an organizationally-sanctioned activity, it has a side effect of requiring that the organization’s infrastructure, on-hand resources, and staffing be configured to enable the checklist to be successfully executed. This function was facilitated, in one deployment of checklists, by making an on-site executive part of the team responsible for deploying checklists. The executive was able to reconfigure the organization’s supply base so that needed materials were on hand, and further was able to persuade a supplier to package materials needed to execute the checklist together. Thus, ultimately, the checklist worked to reconfigure the organization and its supply chain.
Details
page 7-10. Philosophers essay on errors distinguishes between errors of ignorance and errors of ineptitude. The first seem more forgivable than the second, but in the context of performance of complex activities under time pressure. the latter seem inevitable.
page x. A patient in an intensive care unit undergoes 178 procedures a day.
page 38. Using a checklist to make sure 4 steps were carried out reduced the 10-day line infection rate from 11% to 0. Other examples showed reductions from 41% to 3% for untreated pain, and 70% to 4% in improper procedures for those on mechanical ventilators (resulting in a 25% decrease in cases of pneumonia).
page 43-44. In the Keystone initiative, getting project manager and executive participation in checklist roll out was key. Executives made sure that the required chlorhexidine soap was available (previously it was available in only 1/3 of the ICUs), and that required sterile drapes were stocked. After a while, the supplier of lines was persuaded to produce a kit that had both the soap and drapes in it.
page 46. In a checklist deployment to hospitals to reduce cardiac arrest fatalities, checklists were deployed to first responders (rescue squad personnel) and first coordinators (hospital operators) even though they were the least powerful. This enabled the organization to prepare by being alerted ahead of time and mustering the needed skills.
pages 65-68. The building construction checklist of both instrumental tasks (put together by 16 disciplines and looked over by subcontractors), and communications activities (“the submittal list” – who talks to whom when about what). By ensuring that the right people are charged with talking at the right time, you radically lower the need for a single person to understand all the details of what is going on.
pages 76-80. Walmart and Katrina and empowering store owners. And Van Halen and brown M&M story as a procedural integrity check.
pages 95-97. The Proctor and Gamble soap in India study. The use of soap was made more systematic, and more pleasant.
pages 99-100: “Cleared for Takeoff” checklist for ensuring timely administration of pre-operative antibiotics. A mechanical forcing function (a metal tent stenciled with “cleared for takeoff over the scalpel that served as both a prompt and a legitimation of the nurse’s role in the process. Increase in proper antibiotic administration went from 60% to 89% (3 months) to 100% (10 months).
page 103. “‘That’s not my problem,’ is probably the worst thing people can think, whether they are starting an operation, taxiing an airplane full of passengers down the runway, or building a thousand-Foot skyscraper. But in medicine, we see it all the time.”
pages 107-110. Introductions among team members increase team affinity and empower lower status members to speak up. “When nurses were given a chance to say their names and mention concerns at the beginning of an operation, they were more likely to note problems and mention solutions.” Employee satisfaction rose 19% and OR nurse turnover went from 23% to 7%
page 120. Good vs. bad checklists. Would be nice to know more about this, rather than the obvious and rather sloganish comments in the book. …Nice point about getting leadership to adopt checklists first.
