Introduction: evidence-based care is the use of the best scientific evidence in making clinical decisions and applying the best care. It is one of the major challenges in nursing interventions. This study aimed to determine the facilities and barriers to evidence-based nursing.

Methods: This was a cross-sectional study including clinical nurses, nurses, managers and nurse educators. The sample size was calculated as 300 by simple random sampling method. Based on Rostas tool, good validity and reliability of r = 0.83 and r = 0.79, respectively, were achieved. To achieve the objectives of the research, SPSS software version 16 was used and data was analyzed by parametric tests (t-test and ANOVA) and Pearson’s correlation coefficient.

Results: In the viewpoint of nurses, the most facilitating training courses were development of methods analysis and evidence application (27.7%) and the biggest barriers were implementation barriers (42.6 ± 2.2) and the lack of easy access to up-to-date and useful information and research (38.12%). There was a meaningful relationship between barriers and facilities scores and negative significance (P = 0.0 2, r = -0.15) between barriers and facilities based on demographic variables other than age and work experience (P < 0.05). There was no statistically significant relationship between other variables.

Conclusions: By removing barriers and providing facilities, support and encouragement for the use of EBP, nursing approaches will change. To achieve this, nurses need ongoing trainings and practice in this field.
