Abstract

Background Scientific advances have resulted in more complex medical systems, which in turn have led to an increase in the number of patient safety incidents. In this environment, the importance of honest disclosure of PSIs is rising, which highlight the need to settle a reliable system. This study aimed to investigate the effects of patient safety culture and ethical awareness on open disclosure of PSIs. Methods Data were collected from 389 nurses using self-reported perceptions of open disclosure of PSIs, perceptions of patient safety culture, and ethical awareness. Results Perception of open disclosure of PSIs was significantly correlated with ethical awareness and perception of patient safety culture. Ethical awareness had the greatest impact on perception of PSIs, and two components of the perception of patient safety culture, namely overall knowledge about patient safety and staffing, were found to have significant effects. Conclusions To enhance nurses’ perception of open disclosure of PSIs, educational curriculum and programs that teach and practice fundamental ethical values are needed. Furthermore, it also calls for effort on the part of healthcare institutions and the government, as well as people’s trust, to implement a legal safety net and foster patient safety culture to promote honest disclosure of PSIs to patients.
