The Association Between Nursing Work Environment and Evidence-Based Practice.

INTRODUCTION: Evidence-based practice (EBP) is essential for improving the quality of care and health outcomes in healthcare organizations. This study aimed to analyze the association between the nursing work environment and EBP elements, including attitude, training, implementation and quality of care. METHODS: A multicenter, cross-sectional study was conducted with 1022 registered nurses from 57 primary care centers and four public hospitals in northern Spain. The Practice Environment Scale of the Nursing Work Index (PES-NWI) was used to assess the nursing work environment. Data collection also included the Health Sciences Evidence-Based Practice (HS-EBP) questionnaire to evaluate attitudes toward EBP, and self-reported measures of EBP training, EBP implementation, and overall quality of care. Odds ratios (OR) and 95% confidence intervals for the association between the nursing work environment and EBP elements were calculated using logistic regression adjusted for sociodemographic and occupational characteristics. RESULTS: Compared to nurses who reported working in unfavorable environments (n = 220; 21.5%), those working in favorable environments (n = 437; 42.8%) exhibited a positive attitude toward EBP (OR = 2.89; 95% CI [2.00, 4.18]), EBP implementation (OR = 2.30; 95% CI [1.52, 3.39]) and higher quality of care (OR = 2.35; 95% CI [1.61, 3.44]). Using a composite measure that considered all EBP elements, favorable environments were associated with overall EBP engagement (OR = 3.47; 95% CI [2.38, 5.07]). The most influential environmental dimensions were adequate staffing and strong nursing foundations. LINKING EVIDENCE TO ACTION: A favorable nursing work environment was strongly associated with a positive attitude toward EBP, the implementation of EBP, and a commitment to providing high-quality care. Key strategies to promote EBP should involve healthcare and academic institutions working together to establish a healthy work environment with appropriate staffing and care foundations rooted in nursing theory.
