> column in Nature suggests studies giving positive results to checklists don't replicate

"In a review of nearly 7,000 surgical procedures performed at 5 NHS hospitals, they found that the checklist was used in 97% of cases, but was completed only 62% of the time8. When the researchers watched a smaller number of procedures in person, they found that practitioners often failed to give the checks their full attention, and read only two-thirds of the items out loud9. In slightly more than 40% of cases, at least one team member was absent during the checks; 10% of the time, the lead surgeon was missing."
