Vanderbilt University Medical Center's QuizTime test-enhanced learning (TEL) platform employed quiz-based microlearning to deliver at-scale continuing education (CE) relevant to the COVID-19 pandemic. The "Conquering COVID" quiz debuted on April 13, 2020, and covered basic science, epidemiology, management and treatment. After taking the quiz, eligible learners could claim three American Medical Association Physician's Recognition Award (PRA) Category 1 credits if they engaged with at least 80% of quiz items. Users were also sent a five-point Likert scale feedback survey to evaluate their experiences with QuizTime. In total, 805 of 1,132 enrollees (71.1%) completed the quiz. This cohort included physicians (28%), nurses (22%), nurse practitioners (14.9%), allied health professionals (11.3%) and other learners. Medicine, pediatrics and family medicine were most commonly represented. Learners made correct responses on 49.4% of first attempts with the quiz and 87.3% of their second responses. The surveys indicated that 91.6% of respondents were satisfied or very satisfied with the QuizTime experience. Most (89.5%) agreed the activity informed and/or reinforced practice habits, while 80.4% found QuizTime superior or far superior to their usual learning methodology. The outcomes demonstrated the feasibility and scalability of virtual quiz-based microlearning, while also meeting rapid production and distribution requirements. "Given its success, this type of education should become a vital component of future continuing professional development," the authors recommend.
