Background and Objectives: One of the most important causes of industrial incidents, of which 90% is related to human factors, is to refuse to accept errors because of fear of blaming and concealing them. In the present study, the relationship between just culture and safety culture was investigated in one of the industrial sections of Tehran. 
Methods: The research was descriptive-analytic and conducted as a cross-sectional study. Out of 320 a sample of 181 staff who worked at the operational and administrative sections were selected in an accessible manner. The research instruments consisted of questionnaires of personal and occupational information, just culture and safety culture. Data was analyzed using, Pearson correlation coefficient and multivariate regression by SPSS22 software.
Results: The relationship between different dimensions of safety culture and just culture is 0.84 (P<0.001). The power prediction of safety culture is based on different dimensions of the just culture 0.70 (P<0.05). Between different dimensions of safety culture, the level of information exchange, education and management commitment are most closely related to mean of just culture. Also, the level of information exchange is the highest and safety priority shows the least link with the just culture. Therefore, the exchange of information can lead to a continuous improvement of the just culture.
Conclusion: Evaluating the just culture, the safety culture of the employees of the organization can be predicted with a high level of certainty, which shows the direct relationship between the just culture and the safety culture. So, increasing the just culture directly contributes to the development of the safety culture.
 

Background and Objective: Adverse events, defined as errors occurring during nursing care, have become one of the most serious threats to patient safety and quality of care in hospitals. This study aimed to investigate the role of various factors influencing adverse events among nurses.

Methods: An analytical epidemiological study was conducted on 360 nurses working in public hospitals in Ahvaz. Data were collected using a personal information questionnaire, an environmental factors checklist, the standardized Patient Safety Culture questionnaire, the NEO Personality Inventory, the Copenhagen Psychosocial Questionnaire assessing psychosocial work factors, and a standardized adverse events checklist. Data analysis was performed using SPSS and SMART PLS software.

Results: The most frequently reported adverse events were complaints from patients or their families, while surgical wound infections were reported less frequently. Additionally, 31 nurses (8.6%) reported more than 20 adverse incidents in the past 12 months. The developed model indicated that environmental noise significantly affects both patient safety culture and adverse events, and psychosocial factors influence patient safety culture; however, patient safety culture alone did not have a significant effect on the occurrence of adverse events.

Conclusion: Overall, the prevalence of adverse events among the studied nurses was high. Exposure to environmental noise and psychosocial factors substantially impacts patient safety culture. These findings can inform strategies to improve adverse event management and enhance patient safety culture.
