[영문]In 2005, HIMSS?Nursing Informatics Task Force surveyed acute care providers across the U.S. to explore the impact of HIT on the role of nurses and interdisciplinary communication in acute care settings. More than 1,700 healthcare professionals responded to the online survey and provided numerous insights into the impact that clinical information systems have in their daily communication and workflow patterns. This paper provides an overview of survey results from four large healthcare delivery systems with a focus on how the results will be employed to support an evidence-based approach to improving acute care IT systems across these healthcare delivery systems. A case study approach is employed to describe survey findings at the healthcare system level and then provide a set of recommendations to leverage findings to capitalize on the strengths of existing IT applications and tools, and work towards overcoming barriers to interdisciplinary communication or acute care workflows.
