Purpose: The purpose of this study was to investigate perception of patient safety culture among
hospital nurses. Methods: There were four steps in this study; education about patient safety
culture, pre-test, nursing activities for patient safety, post-test. A questionnaire was distributed twice
to all nurses in one hospital. Pretest data were collected from April 1 to April 20 and posttest
from November 15 to November 25, 2013. For the pretest data, 302 data sets were analyzed and
for the posttest, 266. SPSS 12.0 was used for descriptive analysis. Results: Overall perception of
nurses on patient safety culture was “moderate“(3.27). For general characteristics, there was a
significant difference in patient safety culture according to work unit and length of employment.
Attitude to leaders was significantly different according to nurses' age, position and work unit.
Organizational culture was significantly different according to nurses' age and work unit. System of
patient safety was significantly different according to work environment. In the posttest, the mean
score improved. Conclusion: Results indicate that patient safety cultural perception is related to
safety during nursing activities and systematic strategies to increase perception should be
expanded through research and the development of new educational programs on patient safety
culture.
