Abstract Background Implementation of evidence‐based practice (EBP) in healthcare remains challenging. The influence of leadership has been recognized. However, few randomized trials have tested effects of an educational and skills building intervention for leaders in clinical settings. Aims Test effects of an EBP leadership immersion intervention on EBP attributes over time among two cohorts of leaders at a national comprehensive cancer center. Methods A stratified, randomized, wait‐list group, controlled design was conducted. Participants received the evidence‐based intervention one year apart (2020, n = 36; 2021, n = 30) with EBP knowledge, beliefs, competencies, implementation self‐efficacy, implementation behaviors, and organizational readiness measured at pre‐ and post‐intervention, and one‐ and two‐year follow‐ups. Participants applied learnings to a specific clinical or organization priority topic. Results Baseline outcomes variables and demographics did not differ between cohorts except for age and years of experience. Both cohorts demonstrated significant changes in EBP attributes (except organizational readiness) post‐intervention. Mixed linear modeling revealed group by time effects at 3‐months for all EBP attributes except implementation behaviors and organizational readiness after the first intervention, favoring cohort 2020, with retained effects for EBP beliefs and competencies at one year. Following Cohort 2021 intervention, at 12‐weeks post‐intervention, implementation behaviors were significantly higher for cohort 2021. Linking Evidence to Action An intensive EBP intervention can increase healthcare leaders' EBP knowledge and competencies. Aligning EBP projects with organizational priorities is strategic. Follow‐up with participants to retain motivation, knowledge and competencies is essential. Future research must demonstrate effects on clinical outcomes.
