Background and Objectives: Nursing errors are a serious threat to patient safety, which can lead to increased public concern and distrust of recipients of health care services and refusal to undergo treatment. Therefore, the present study examines types of causes of nurses' errors, reasons for not reporting them and ways to reduce errors.
Methods: The present study was a narrative review study of English and Persian articles on nurses' errors in the period (2008-2018) and was done in 2019. Articles were searched in three internal databases such as SID, Magiran and Iran Medex and five external databases of Google Scholar, PubMed, Scopus, Science Direct, and Springer.
Results: Most nursing errors were in the form of functional errors. Risk factors were divided into nurse, organization, ward, and patient-related error factors. The reasons for nurses' failure to report errors include professional reputation and legal problems. Error reduction strategies are such as nursing education and management controls.
Conclusion: Nursing errors have been studied in various ways. These studies are not only aimed at identifying nurses' errors, but also to enhance knowledge and knowledge about the possible causes and preventive factors. The benefits of this view of the articles lead to the provision of appropriate health care services, proper planning for hospitals by managers, and the advancement of nursing education. However, fewer studies have used modern methods of hazard identification.

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.
