INTRODUCTION: As an emerging and rapidly growing specialty, academic hospitalists face unique challenges in career advancement. Key mentoring needs, especially developing reputation and relationships outside of their institution are often challenging. METHODS: We describe the structure of a novel Visiting Professorship in Hospital Medicine Program. It utilizes reciprocal exchanges of hospitalist faculty at the rank of late assistant to early associate professor. The program is designed explicitly to facilitate spread of innovation between institutions through a presentation by the visiting professor and exposure to an innovation at the host hospital medicine group. It provides a platform to advance the career success of both early- and midcareer hospitalist faculty through 1-on-1 coaching sessions between the visiting professor and early-career faculty at the host institution and commitment by visiting professors to engage in mentoring after the visit. RESULTS: Five academic hospitalist groups participated. Seven visiting professors met with 29 early-career faculty. Experience following faculty exchange visits demonstrates program effectiveness, as perceived by both early-career faculty and the visiting professors, in advancing the goals of mentorship and career advancement. One-year follow-up suggests that 62% of early-career faculty will engage in subsequent interactions with the visiting professor, and half report spread of innovation between academic hospital medicine groups. CONCLUSIONS: The Visiting Professorship in Hospital Medicine offers a low-cost framework to promote collaboration between academic hospital medicine groups and facilitate interinstitutional hospitalist mentoring. It is reported to be effective for the goal of professional development for midcareer hospitalists. Journal of Hospital Medicine 2016;11:714–718. © 2016 Society of Hospital Medicine.
