Purpose: This study examined factors associated with job satisfaction among physician assistant nurses working across diverse tasks and clinical settings. Methods: From March 18 to April 2, 2025, we surveyed physician assistant nurses at a tertiary hospital in Daegu and data from 141 participants were analyzed. Analyses included descriptive statistics, the independent t-test, one-way analysis of variance, Pearson correlation coefficients, and hierarchical multiple regression. Results: Self-efficacy (β=.47, p<.001) and role conflict (β=-.19, p=.008) were significantly associated with job satisfaction, and the final model explained 32.2% of the variance. Conclusion: Strategies to improve job satisfaction should reduce role conflict and strengthen self-efficacy through education and competency-development programs. Clearer work regulations and legal and institutional safeguards may also support physician assistant nurses.

Purpose: This study explored the factors associated with burnout in medical support staff nurses in tertiary hospitals. Method: A descriptive cross-sectional design was used. Data were collected from 150 medical support staff nurses working in five tertiary hospitals across three metropolitan cities between March 7 and 21, 2025. Data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, Pearson correlation coefficient, and hierarchical multiple linear regression analysis. Results: The factors associated with burnout are listed in the following order: role conflict (B=11.99, p<.001), types of department (e.g., Dermatology and Pediatrics) (B=11.25, p=.018), and job autonomy (B=-3.78, p=.045). The explanatory power of these factors for burnout was determined to be 26.5%. Conclusion: The findings highlighted that role conflict should be addressed to prevent and reduce burnout among medical support staff nurses. These findings are expected to serve as foundational data for developing department-specific education and competency-enhancement programs for medical support staff nurses. In addition, to enhance autonomy and responsibility, it is necessary to establish clear work regulations that allow for lawful and accountable performance of duties, thereby contributing to the reduction of burnout.

Purpose: The purpose of this study was to investigate the level of sleep quality among older adults with mild cognitive impairment (MCI) at long-term-care (LTC) hospitals and identify the related sleep-quality factors.Methods: This study was a descriptive study. A total of 150 older adults with MCI at 5 LTC hospitals participated in this study. Data analysis was conducted using descriptive analysis, t-test, ANOVA, Pearson's correlation and stepwise multiple regression with SPSS/20.0 program.Results: The significant related factors to sleep quality of older adults with MCI at LTC hospitals were shown as pain (β=.44, p<.001), environment (β=.26, p<.001) and number of diseases (β=.14, p=.032). Total explained variance was 39.8% (F=4.67, p=.032).Conclusion: Nursing care to control pain and number of disease in older adults with MCI must be developed for improving LTC hospitals’ environments and residents’ sleep quality. This study provides the basic data to develop sleep management programs of MCI older adults at LTC hospitals.

Aim: The purpose of this study was to identify the incidence of postoperative delirium in PCC (patients with colorectal cancer) and the related factors of postoperative delirium by analysing the differences in the general, disease‐related and operation‐related characteristics.Background: Previous studies had some limitations in generalising the risk factors for postoperative delirium in PCC due to the lack of relevant factors, such as disease‐ and operation‐related characteristics. There is a need to investigate the factors of postoperative delirium by including cancer and surgical characteristics.Design: The current study is a cross‐sectional study to investigate the correlated factors of postoperative delirium in PCC.Methods: A total of 196 patients who underwent colorectal cancer surgery at the Keimyung University Dongsan Hospital in Korea participated in the study. Data collection was performed from 15 August 2018 to 10 July 2019. Patients’ general, disease‐related and operation‐related characteristics were collected from questionnaires and electronic medical records. Data analysis was performed using descriptive statistics, t test, Chi‐square test and logistic regression using SPSS/WIN 22.0. The STROBE checklist has been used to report this study.Results: The results of this study showed that 26 (13.2%) PCC exhibited postoperative delirium and the risk factors for postoperative delirium were physical activity (OR = 2.94, p = .001), infection (OR = 2.17, p = .001) and nutritional status (OR = 1.10, p = .028).Conclusion: To reduce and prevent the occurrence of postoperative delirium in PCC, encouraging participation in physical activity before and after surgery are required, and regular monitoring of the infection symptoms and nutritional status.Relevance to clinical practice: Based on the results of this study, postoperative delirium in PCC could be decreased by encouraging physical activity immediately following operation, monitoring the signs and symptoms of infection using diverse objective laboratory findings and maintaining the nutritional status within the normal range.
