Nurses' perception of patient safety culture and its relationship with adverse events: a national questionnaire survey in Iran.

Background: Patient safety culture is an important factor in determining hospitals' ability to address and reduce the occurrence of adverse events (AEs). However, few studies have reported on the impact of nurses' perceptions of patient safety culture on the occurrence of AEs. Our study aimed to assess the association between nurses' perception of patient safety culture and their perceived proportion of adverse events.
