EvidenceBased Practice for Advanced Practice Emergency Nurses, Part III: Planning, Implementing, and Evaluating an EvidenceBased Small Test of ChangeShapiro, Susan E. RN, PhD; Donaldson, Nancy A. RN, DNS, FAANAdvanced Emergency Nursing Journal: July/September 2008 - Volume 30 - Issue 3 - p 222–232 doi: 10.1097/01.TME.0000334374.36905.69 Article Abstract Author Information In this article, we describe the steps involved in implementing an evidence-based practice change in an emergency department. Using the hypothetical case of changing from a 3-tier to a 5-tier triage system, we present an overview of change theory, microsystem analysis, and rapid cycle change. We then provide practical as well as theoretical suggestions for planning, implementing, and evaluating an evidence-based practice change. We also provide practical tools for conducting a gap analysis and creating a project plan that advanced practice emergency nurses will find useful as they take on this leadership role in their department.
