The relationship between patient safety culture and adverse events in Iranian hospitals: a survey among 360 nurses.

Background: Adverse events have become a global problem and are an important indicator of patient safety. Patient safety culture is essential in efforts to reduce adverse events in the hospital. This study aimed to investigate the status of the patient safety culture, the frequency of adverse events, and the relationship between them in Qazvin's hospitals in Iran.

Methods: The present study is a descriptive-analytical study conducted in six hospitals in Qazvin, Iran, in 2020. The study population was nurses working in Qazvin hospitals. We collected data via a patient safety culture questionnaire and an adverse event checklist. Three hundred sixty nurses completed questionnaires. Multiple logistic regression was used to investigate the relationship between variables.

Results: The highest mean of patient safety culture was related to the organizational learning dimension (3.5, SD = .074) and feedback and communication about errors (3.4, SD = 0.82). The participants gave the lowest score to dimensions of exchanges and transfer of information (2.45,=0.86) and management support for patient safety (2.62,Sd = 0.65). Management's support for patient safety, general understanding of patient safety culture, teamwork within organizational units, communication and feedback on errors, staff issues, and information exchange and transfer were significant predictors of adverse events.

Conclusion: This study confirms patient safety culture as a predictor of adverse events. Healthcare managers should provide the basis for improving the patient safety culture and reducing adverse events through methods such as encouraging the reporting of adverse events and also holding training courses for nurses.
