Conceptualizing vaccine champions from an implementation science perspective: Findings from a national survey of primary care health professionals

Abstract

ObjectiveClinical champions are healthcare professionals who help their colleagues improve the delivery of evidence-based care. Because little is known about champions working in the context of adolescent vaccination, we sought to identify vaccine champion roles among primary care health professionals (PCHPs). MethodsIn 2022, we surveyed 2527 US PCHPs who serve adolescents. The survey assessed the extent to which respondents identified as vaccine champions and the activities they performed. Guided by the Consolidated Framework for Implementation Research, we used these data to categorize PCHPs as: champions who led projects to increase vaccination rates (“implementation leaders”); facilitating champions who more generally shared vaccination data, information, and encouragement (“facilitators”); or non-champions. We used multinomial logistic regression to identify correlates of being a leader or facilitator as opposed to a non-champion. ResultsAbout one-fifth (21%) of PCHPs were implementation leaders, one-quarter (25%) were facilitators, and the remainder (54%) were non-champions. Leaders were more common among PCHPs with medium or high versus low practice experience (31% and 36% versus 20%, both p < .01) and adolescent patient volume (29% and 39% versus 17%, both p < .01). Being a facilitator was also associated with higher practice experience and patient volume. Leaders and facilitators reported a similar number of barriers to their work (mean = 1.8 and 1.9, respectively), with time and competing quality metrics being most common. ConclusionsOur findings suggest that both implementation leaders and facilitators are common vaccine champions in adolescent primary care. These champions are more often found among PCHPs with higher experience and patient volume.
