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. Methods A cross-sectional survey was carried out among 2295 nurses employed in thirty-two teaching hospitals in Iran. Nurses completed the Persian version of the hospital survey of patients’ safety culture between October 2018 and September 2019. Results Positive Response Rates of overall patient safety culture was 34.1% and dimensions of patient safety culture varied from 20.9 to 43.8%. Also, nurses estimated that the occurrence of six adverse events varied from 51.2–63.0% in the past year. The higher nurses’ perceptions of “Staffing”, “Hospital handoffs and transitions”, “Frequency of event reporting”, “Non-punitive response to error”, “Supervisor expectation and actions promoting safety”, “Communication openness”, “Organizational learning continuous improvement”, “Teamwork within units”, and “Hospital management support patient safety” were significantly related to lower the perceived occurrence at least two out of six AEs (OR = 0.69 to 1.46). Conclusions Our findings demonstrated that nurses’ perception regarding patient safety culture was low and the perceived occurrence of adverse events was high. The research has also shown that the higher level of nurses’ perception of patient safety culture was associated with lowered occurrence of AEs. Hence, managers could provide prerequisites to improve patient safety culture and reduce adverse events through different strategies, such as encouraging adverse events’ reporting and holding training courses for nurses. However, further research is needed to assess how interventions addressing patient safety culture might reduce the occurrence of adverse events.
Aim To determine correlations for nurse self‐reported occupational stress, prevalence of cognitive failure (CF), and adverse events. Design Cross‐sectional nationwide survey. Methods Tertiary‐level public hospitals (N = 115) from 13 provinces in Iran were recruited and 2,895 nurses surveyed (August 2016–December 2017). Participants’ self‐reported demographic information, occupational stress, CF, and frequency of adverse events were analysed using chi‐square, t tests, and binary logistic regression. Results This study showed that 29.1% of nurses had experienced adverse events in the past six months. Significant predictors for reported adverse events from logistic regression were ‘Role stressors’, ‘Interpersonal relations stressors’, and ‘Action’, while ‘Working environment stressors’ was protective for reported adverse events. Demographic predictors of adverse events were longer work hours and male gender, while those working in critical care units, general wards, and other wards had higher reported adverse events than for emergency wards. Conclusions Occupational stress and CF are associated with the reporting of adverse events. Further research is needed to assess interventions to address occupational stress and CF to reduce adverse events. Impact Adverse events compromise patient safety, lead to increased healthcare costs, and impact nursing staff. Higher self‐reported adverse events were associated with higher reported stressors and CF. Understanding the factors that influence occupational stress, CF, and adverse events will support quality patient care and safety.
