Purpose: The purpose of this study was to investigate the effect of SBAR communication program on nurse's perception about communication and attitudes toward patient safety. Methods: A single-group pre-post experimental study was conducted. A SBAR education program was provided to 167 nurses working in 9 general wards of a hospital in Seoul. A total of 153 questionnaires were included for the final analysis. Statistical analysis included analysis of variance, paired sample t-test, and Cochran-Mantel-Haenzel test. Results: After applying SBAR communication education, nurses perceived significant improvement in three of the five categories of communication between nurses and doctors; satisfaction (p=.001), accuracy (p=.001), and understanding (p=.002). The indicators of communication between nurses were also improved significantly in the order of accuracy (p=.001), satisfaction (p=.001), shift communication (p=.001), and openness (p=.016). The scores of nurse's attitudes toward patient safety demonstrated a significant increase in the five categories out of the six; perception of management (p=.001), working condition (p=.001), safety climate (p=.001), teamwork climate (p=.001), job satisfaction (p=.012). Conclusion: It is recommended that nurses and doctors use SBAR communication in their practice. Developing education programs and utilization methods is required for the effective establishment of SBAR communication.
