As a group of Health System Impact (HSI) postdoctoral fellows, Sim and colleagues offer their reflections on 'driving change' within the health system and present a framework for understanding the HSI fellow as an embedded researcher. Our commentary offers a different perspective of the fellow's role by highlighting the integrated knowledge translation (IKT) approach we consider to be foundational to the fellowship experience. Further, we provide several recommendations to enhance Sim and colleagues' framework to ensure we capture the full value of the fellowship program to the HSI fellow, health system organization, and academic institution.
