The Health System Impact Fellowship: Perspectives From the Program Leads Comment on "CIHR Health System Impact Fellows: Reflections on 'Driving Change' Within the Health System".

As the Canadian Institutes of Health Research (CIHR) leads in designing and implementing the new Health System Impact (HSI) Fellowship program, we congratulate Sim et al for their thoughtful contribution to the nascent literature on embedded research, and for advancing our own learning about the HSI Fellowship experience. In our commentary, we describe the HSI Fellowship and its key components, discuss the factors that motivated and inspired the creation of the program, and highlight successes thus far.
