Purpose
This study examined factors influencing patient safety nursing activities in integrated nursing care units. Methods: A survey was conducted with 134 nurses from hospitals (100~300 beds) in Busan using self-administered questionnaires (August 17–September 15, 2024). Data were analyzed using descriptive statistics, Pearson correlation, and multiple regression analysis. Results: The mean score for patient safety nursing activities was 4.31±0.55. Positive correlations were found with grit, teamwork, communication, and patient safety culture awareness. The predictor variables explained 46.0% of the variance in patient safety nursing activities. Significant factors included communication (β=.31, p=.032) and leadership (β=.29, p=.035) within teamwork, incident reporting frequency (β=.24, p<.001) within patient safety culture awareness, and experience in patient safety education (β=.17, p=.018). Conclusion: The findings of this study highlight the importance of enhancing teamwork, particularly in leadership and communication, and creating a safety culture that promotes incident reporting and education to strengthen patient safety nursing practices. Improving patient safety training, developing systematic evaluation and feedback mechanisms, and establishing structured support systems through campaigns and workshops will boost staff involvement and elevate the quality of patient safety practices.

Purpose
This study aimed to identify the effects of shared leadership, communication skills, and team effectiveness, as perceived by nurses and nursing assistants in comprehensive nursing service units.
Methods
A cross-sectional research design was adopted, and the sample included 306 nurses, nurse assistants, and caregivers working in nine hospitals with fewer than 500 beds in two South Korean cities. The data were analyzed using descriptive statistics, t-tests, ANOVA, Pearson’s correlation coefficient, and four-step hierarchical regression analysis.
Results
The factors influencing team effectiveness in the hierarchal multiple regression analysis were shared leadership (β=.57, p<.001) and communication skills (β=.18, p<.001). These factors explained 49% of the total variance.
Conclusion
To enhance team effectiveness in compressive nursing service units, educational programs focusing on shared leadership and communication skills among nurses, nursing assistants, and caregivers must be developed.
