An evidence-based structure for transformative nurse executive practice: the model of the interrelationship of leadership, environments, and outcomes for nurse executives (MILE ONE).

Identifying and measuring success within the chief nurse executive (CNE) population have proven complex and challenging for nurse executive educators, policy makers, practitioners, researchers, theory developers, and their constituents. The model of the interrelationship of leadership, environments, and outcomes for nurse executives (MILE ONE) was developed using the concept of consilience (jumping together of ideas) toward limiting the ambiguity surrounding CNE success. The MILE ONE is unique in that it links existing evidence and identifies the continuous and dependent interrelationship among 3 content areas: (1) CNE; (2) nurses' professional practice and work environments; and (3) patient and organizational outcomes. The MILE ONE was developed to operationalize nurse executive influence, define measurement of CNE success, and provide a framework to articulate for patient, workforce, and organizational outcome improvement efforts. This article describes the MILE ONE and highlights the evidence base structure used in its development.
