Success is going from failure to failure with no loss of enthusiasm.
Winston Churchill
Imagine for a minute. Imagine in 2013 that the national rate of aspirin use for secondary prevention of coronary artery disease (CAD) is 30%. Imagine that a well-designed, randomized controlled trial of clinical decision support increases the use of aspirin from 30% to 40%. Imagine that the sample size is sufficiently large so that the trial results in a P value of less than .01. Because this was a successful, statistically significant trial, imagine calls to disseminate this intervention with a goal of increasing aspirin use for outpatients with CAD nationwide to 40%.
