Upgrading the American Association of Critical-Care Nurses' Evidence-Leveling Hierarchy

Abstract

In August 2008, the American Association of Critical-Care Nurses' (AACN's) Evidence-Based Practice Resource Work Group met to review current AACN Practice Alerts and to identify new Practice Alerts to be created. The work group was also tasked with reassessment of the grading system used by AACN that evaluates evidence associated with the Practice Alerts and other AACN resources. This article details the effort of this national volunteer work group, specifically highlighting the development of the new AACN evidence-leveling hierarchy system.
