Purpose: The purpose of this study was to identify the impact of the nursing work environment, nursing informatics competency, and missed nursing care on the quality of nursing services. Methods: This was a path analysis study that constructed a hypothetical path model for the variables and examined the model's goodness of fit and effects. Data were collected from nurses who consented to participate in the study between May 19 and June 5, 2025. Results: Analysis of the research model revealed that nursing informatics competency had a direct effect on missed nursing care (β=-.26, p=.001), while the nursing work environment did not have a significant impact on missed nursing care. The nursing work environment showed a direct effect (β=.17, p=.005) and a total effect (β=.20, p=.003) on the quality of nursing services. Nursing informatics competency had a direct effect (β=.39, p=.001), an indirect effect (β=.06, p<.001), and a total effect (β=.44, p=.001) on the quality of nursing services. Missed nursing care showed a direct effect (β=-.22, p=.001) on the quality of nursing services. The explanatory power of the variables for the quality of nursing services was 32.4% in total. Conclusion This study identified specific pathways through which nursing work environment, nursing informatics competency, and missed nursing care influence the quality of nursing services, and demonstrated that missed nursing care plays a partial mediating role between nursing informatics competency and the quality of nursing services.

Purpose: : The study was conducted to examine effects of nurses’ communication styles perceived by surgical patients and their anxiety and uncertainty on patient satisfaction. Methods: : Data were collected by using a structuralized questionannaire which consists of nurses’ communication style tool, State trail Anxiety Inventory(STAI), Mishel Uncertainty in Illiness scale, and patient satisfaction tool targeting on 276 surgical patients who were hospitalized in general wards from July 24, 2020 to December 18, 2020. The data analysis was done with the correlation analysis and the multiple regression analysis. Results: : Nurses’ communication style perceived by surgical patients has found to have the most informative communication styles and the least authoritative communication style. And the variable which has the most effect on patient satisfaction was the affective communication style(β=.35, p<.001), followed by nurse communication importance perceived by surgical patients(β=.15, p=.001). And surgical patients' anxiety (β=-.15, p=.011) and uncertainty(β=-.13, p=.024) has found to have a negative effect on patient satisfaction. Conclusion : The patient satisfaction got higher when the surgical patients perceived the Affective & informative communication styles among nurses’ communication styles, and when they perceived the nurses’ communication as important.
