However, the impact nursing certification has on clinical patient outcomes remains unclear. Purpose: The purpose was to examine the relationship between nursing certification and clinical outcomes. Methods: A systematic review of the literature was conducted through the search of relevant bibliographic databases (CINAHL Plus, PubMed, Medline, and Cochrane Collaboration). Results: Nursing certification was found to have a significant inverse relationship to patient falls and health care–associated infections. Significant correlations were not established in outcomes such as pressure injuries and mortality. Conclusions: The validation of knowledge through nursing certification has an impact on specific outcomes such as patients falls and health care–associated infections. © 2019 Wolters Kluwer Health, Inc.
