Read the new JGIM supplement, “The Science of Electronic Health Record Transitions.” Funded by the VA Office of Research and Development, Health Services Research and Development (HSR&D) Service, this supplement was designed to help address the many issues that can accompany a healthcare system’s transition to a new electronic health record (EHR) system. We wish to thank supplement editors Michael Weiner, MD, MPH; Seppo Rinne, MD, PhD; David A. Haggstrom, MD, MAS; and Elizabeth M. Yano, PhD, MSPH for their work in shepherding this excellent research into the field. [LINK:]
