This study was to describe nurses' research activities, perceptions and performances of evidence-based practice and barriers to the use of research evidence in nursing practice in Korea.

A cross-sectional survey design was used. A questionnaire, except for Barriers Scale, was developed for the study. Data was collected from a convenient sample of 437 registered nurses working at research and education oriented university hospitals.

Nurses' research-related activities were relatively low compared to previous studies. Also perceptions and performances of evidence based nursing practice were low. Preferred informational resources for clinical decision making were identified as ward manuals/clinical guidelines, manager/senior nurses, and literature/research. The major barriers to research utilization were a lack of implication for practice along with inadequate facilitation to implement research evidence and difficulty understanding research written in English. Priorities of barriers factor were Administrator, Communication, Adopter, and Research.

The findings provide directions for future training, education, and managerial policy to achieve successful evidence based nursing practice.
