As the data and stories in this book demonstrate, small changes in behaviors can have a disproportionate effect on outcomes. In chapter three, I used the Archimedes lever to make that point, invoking the phrase “give me a lever and a place to stand, I can move the earth.” Dr. Michael Bennick, the senior doctor described in that chapter, did “move the earth,” so to speak. Wanting to help hospital patients sleep better at night, he didn’t launch some large-scale bureaucratic transformation to make the hospital quieter. Rather, he told the attending nurses and physicians that they should wake him first if they wanted to wake a patient during the night to take a blood sample. No one did. That small alteration changed hospital care and led to a dramatic improvement in the patients’ “quiet at night” score from the 16th to 47th percentile. A minute lever, with a big outcome.
