Abstract
Abstract: The mastery of clinical scholarship and analytic methods for evidence-based practice (EBP) is a published essential for nurse practitioner (NP) education; however, retention of EBP-related knowledge during NP education remains unknown. We assessed EBP knowledge during a first-semester research course and again during the last semester using an item response model. We found that changes depended on the exam item, with performance dropping on a third of the items. Our findings suggest a need to integrate EBP concepts across curricula (e.g., feedback loops in courses other than the research course) to retain these essential skills.
