Champions play an influential, yet understudied role in evidence-based implementation in nursing homes. This study explored the role of nursing home champions who implemented Preferences for Activity and Leisure (PAL) Cards as part of a quality improvement project. PAL Cards are a communication tool that alerts team members to residents’ important preferences. Nursing homes (n = 35) identified champions that created PAL Cards for 15–20 residents. Monthly interviews (n = 88) with champions were coded using the Consolidated Framework for Implementation Research (CFIR) domain “Characteristics of the Individual.” Champions who recruited a supportive team and who could articulate the expected benefits of PAL Cards, showed high implementation success.
