The paper, published online in Annals of Surgery [full text here], looked at 5,295 operations done in two Norwegian hospitals. The intervention was a 20-item checklist consisting of three critical steps–the sign in before anesthesia, the timeout before the operation began, and the sign out before the surgeon left the operating room. Using a stepped wedge cluster design, patients were randomized to control or the checklist.

A look at Table 2 finds that of 27 complications or groups of complications, 14 occurred in significantly fewer patients in the checklist group.

Of the significant 14, a few, such as cardiac or mechanical implant complications, could possibly have been prevented by the implementation of the checklist.
