Purpose: Today's clinical nurses deal with complex problems that need accurate evidence for practice and decision making. In this study the effectiveness of an EBP education program was examined. Methods: A pre-posttest design was used for this study and participants were 46 nurses working at a tertiary hospital located in Suwon, Korea. Date collection was done before and after the education program, from July 27 to October 2, 2015. Data were analyzed using paired t-test and ANCOVA with SPSS 21.0. Results: There were significant differences in scores before and after the EBP education program for EBP readiness: belief (t=-5.65, p<.001), implementation(t=-2.89, p=.006), competence (t=-4.21, p<.001), and for evidence-based decision making (t=-16.25, p<.001) by the nurses. Conclusion:The findings indicate that the EBP education program has positive effects on EBP belief, implementation, competence and evidence-based decision making. In the future, it is necessary to reinforce the content of the program in the clinical workplace and to provide continuous education for clinical nurses.

Findings show that the KICDST has high sensitivity and specificity. Therefore, this screening tool is recommended for early identification of delirium in intensive care patients.
