The Second Society for Simulation in Healthcare Research Summit: Beyond our Boundaries.

STATEMENT: In this article, we report on the Second Society for Simulation in Healthcare Research Summit held in 2017. This meeting succeeded the First Research Summit from 2011 with the goal of advancing the scope of healthcare simulation research. During the one and a half day summit, some of the world's leading experts in simulation, healthcare, and simulation in healthcare convened to discuss ideas about what research goals would be most beneficial to the healthcare simulation community, and what could be done to achieve them. We describe the rationale for the meeting, the organization, the program, and the articles that emerged from the Summit, which are found in this supplemental issue of Simulation in Healthcare.
