RESUMEN
Evidence-based practice (EBP) is crucial in keeping nurses aware of the current knowledge and improving clinical decision-making. The integration of nurses' EBP competencies and organizational support has been suggested to create an effective arena in implementing EBP. The purpose of the study was to examine organizational factors influencing nurses' EBP knowledge, attitudes, and implementation and identify staff nurses' perceptions of EBP nursing leadership and hospital supports in Saudi Arabia. Data were collected from a convenience sample of staff nurses (N = 227) working in four hospitals using a cross-sectional, correlational descriptive design. Level of education (p < 0.05), EBP training (p < 0.05), unit type (ICU (p < 0.001) and ER (p < 0.01)), perceived nursing leadership (p < 0.001), and work environment (p < 0.05) supports were found significantly associated with nurses' knowledge. Magnet recognition (p < 0.01) and knowledge (p < 0.001) had significant influence on nurses' attitudes. Unit type (ER) (p < 0.05), knowledge (p < 0.001), and attitudes (p < 0.001) were associated with implementation. Encouragement to attend EBP trainings from nursing leadership was perceived by most nurses (51.1%). Nurses reported their hospitals support EBP through training (68.2%). Findings support the need for healthcare systems to create a culture that facilitates EBP implementation to enhance nurses' EBP competencies and improve patients' outcomes. Nursing managers may consider preparing nurses through education.
