Abstract

Existing studies have identified specific factors influencing some dimensions of evidence-based practice (EBP) competence and use. However, the way these factors interact still needs to be clarified. The purpose of the study was to test a model based on the Determinant Frameworks that explain the relationships and the direct pathways between the characteristics of the nurses, the context, and the implementation strategies and the dimensions of EBP competence, attitude, knowledge, skills, and use of EBP. A cross-sectional study was carried out in Spain during January and February 2020, involving 2,370 nurses employed in public health centers across all autonomous communities within the National Health System. An online survey was administered to gather data, addressing various topics related to the nurses’ characteristics, the context in which they worked, the implementation strategy, and their competence in evidence-based practice (EBP). As depicted in the conceptual framework, a structural equation model was constructed to test the hypothesized relationships among key study variables. The model obtained showed a good fit (χ2/df = 3.20, p<0.001; RMSEA = 0.030 [90% CI 0.025, 0.036]; CFI = 0.989; GFI = 0.990; TLI = 0.983). The context, more specifically, the dimensions of nurse participation in the center’s affairs, nursing foundations for quality of care, nurse manager ability leadership and support of nurses, and implementation strategy have a direct and positive effect on EBP use. Training in EBP, reading scientific articles, and having a doctorate are associated with higher competence and knowledge in EBP. The final fit shows the #Evidencer model for the use of EBP (#EvidencerMUSEBP) with two main components: the contextual and strategic factors that influence the implementation of EBP and the characteristics of the professionals, such as their training and reading of articles, which have an impact on EBP competence. This model could guide healthcare organizations in proposing comprehensive interventions to improve EBP use and the competency of nurses.
