Visual analysis of global comparative mapping of the practice domains of the nurse practitioner/advanced practice nursing role in respondent countries

Background: Internationally, there is increasing demand for nurse practitioner (NP) and advanced practice nursing
(APN) roles; however, high variability exists in how NP/APN roles are defined and understood.
Purpose: The aim of this research was to improve our understanding of how the NP/APN is defined globally by: 1)
examining role definitions, competencies, and standards of practice for advanced practice nurses internationally; 2)
describing from a global perspective the core concepts and common features of NP/APN associated with practice
domains; and 3) exploring the utility of text mining and visual analytics in identifying the clustered core concepts
common to NP/APN roles organized around the five advanced practice domains of the Strong Advanced Practice Model.
Methods: This article describes the findings of a secondary analysis of an international NP/APN competency
mapping project, using innovative text mining and visual analysis techniques to reexamine and summarize the
NP/APN role in 19 countries from Africa, Australia, Asia, Europe, and North America.
Results: Although weak aggrupation/associations suggest that further work is needed to define the domains of
advanced practice with associated model development, visual analysis points to the identification of common concepts
and linkages between concepts for each practice domain of advanced practice outlined in the Strong Model.
Implications for practice: The secondary text mining and visual analysis presented in this article allows for comparison
of core elements between advanced practice role descriptions, standards, and competencies globally to ultimately
provide a global perspective on the common features of NP/APN roles and areas where further delineation is required.
