Safety culture survey among medical residents in Japan: a nationwide cross-sectional study.

PURPOSE

This study aimed to examine safety culture among Japanese medical residents through a comparative analysis of university and community hospitals and an investigation of the factors related to safety culture.

METHOD

This nationwide cross-sectional study used a survey to assess first and second-year medical residents' perception of safety culture. We adapted nine key items from the Safety Awareness Questionnaire to the Japanese training environment and healthcare system. Additionally, we explored specific factors relevant to safety culture, such as gender, year of graduation, age, number of emergency room duties per month, average number of admissions per day, incident experience, incident reporting experience, barriers to incident reporting and safety culture. We analysed the data using descriptive statistics and multivariate logistic regression analysis.

RESULTS

We included 5289 residents (88.6%) from community training hospitals and 679 residents (11.4%) from university hospitals. A comparative analysis of safety culture between the two groups on nine representative questions revealed that the percentage of residents who reported a positive atmosphere at their institution was significantly lower at university hospitals (81.7%) than at community hospitals (87.8%) (p<0.001). The other items were also significantly lower for university hospital residents. After adjusting for multivariate logistic analysis, university hospital training remained significantly and negatively associated with all nine safety culture items. Furthermore, we also found that university hospital residents perceived a significantly lower level of safety culture than community hospital residents.

IMPLICATIONS

Further research and discussion on medical professionals' perception of safety culture in their institutions as well as other healthcare professionals' experiences are necessary to identify possible explanations for our findings and develop strategies for improvement.
