Study Summary
Two memory research findings (the spacing and testing effects) can dramatically improve retention of learning, but they have largely have been ignored by educators. The researchers have developed a novel form of online education (termed 'spaced education') based on these two effects which has been shown in randomized trials to improve knowledge acquisition and boost learning retention. Using prostate cancer screening as an experimental system, the researchers investigated whether spaced education could durably improve clinicians' behaviors, not just their knowledge.
Primary Outcome
The primary outcome measure was the difference in the percentage of inappropriate PSA screening performed by clinicians in the spaced education and control cohorts. Based on published clinical guidelines and reports, inappropriate PSA utilization was defined as the use of PSA for prostate cancer screening in patients \>76 or \<40 years old, or with an estimated life expectancy of less than 10 years.
