Gawande now has a book out about checklists called "The Checklist Manifesto: How to Get Things Right" that expands on this and also describes the usefulness of checklists in other areas: http://www.amazon.com/Checklist-Manifesto-How-Things-Right/dp/0805091742 (If the topic interests you, btw, Amazon apparently is selling this $24.50 hardcover book for only $10).
