Purpose
This study analyzed the methodological characteristics of machine learning (ML) applications in nursing research, evaluated their reporting quality against standardized guidelines, and assessed progress toward clinical implementation. Methods: A PRISMA-compliant systematic review (PROSPERO CRD42024595877) searched nine English- and Korean-language databases through September 27, 2024. Included studies applied ML to a nursing question and had at least one nursing-affiliated author. Two reviewers independently extracted data following the Cross-Industry Standard Process for Data Mining (CRISP-DM) framework. Reporting quality was appraised using the TRIPOD+AI checklist. Results: Of 125 included studies, supervised learning predominated (93.6%), with random forest, logistic regression, and support vector machines as common algorithms. The most frequent performance metrics were the area under the receiver operating curve and accuracy. Mean TRIPOD+AI compliance was 50.4% (standard deviation=9.37), with reporting quality lowest for data preparation (48.0%) and class imbalance handling (22.4%). Research focused on predicting pressure injuries, falls, and readmissions. Only seven studies described clinical deployment, often citing ethical or workflow barriers. Conclusion: While ML studies in nursing are increasing and show strong discriminatory accuracy, their impact is limited by inconsistent reporting, limited external validation, and rare clinical deployment. Translating these algorithms into practice requires adopting comprehensive reporting guidelines like TRIPOD+AI, documenting each CRISP-DM phase, and integrating nurse-centered decision-support pathways.

Purpose
This study aimed to clarify the concept of nursing competence in coping with clinical deterioration by employing Rodgers’ evolutionary concept analysis, which reflects both sociocultural and temporal dimensions. Methods: A six-step concept analysis was conducted following Rodgers’ methodology. A systematic literature review was performed using PubMed, Embase, CINAHL, and Google Scholar, yielding 35 relevant studies published between 2000 and 2025. Data extraction followed the Joanna Briggs Institute template, and quality was appraised using the STROBE checklist. Results: Four key attributes of nursing competence were identified: technical skills in patient monitoring, situational awareness and clinical intuition, decision-making regarding escalation of care, and communication and teamwork to ensure timely intervention. Antecedents included formal education, clinical experience, and institutional support. Consequences encompassed enhanced patient safety, increased nurse confidence, and greater professional autonomy. The concept was demonstrated to be dynamic and influenced by healthcare policies, such as the implementation of rapid response systems. Conclusion: Nursing competence in managing clinical deterioration is a multidimensional and evolving concept that is essential for patient safety. Clarification of this concept can inform the development of assessment tools and simulation-based education. Further research should explore its application across diverse healthcare contexts and address challenges related to escalation of care.

Purpose
This study aimed to develop and evaluate the effectiveness of a health management program using a mobile application for middle-aged men experiencing andropause. Methods: A quasi-experimental design with a non-equivalent control group pretest-posttest structure was employed. The study took place from June 27 to August 30, 2024, with participant recruitment occurring from June 27 to July 10, 2024. In total, 61 participants (30 in the experimental group and 31 in the control group) participated from July 15 to August 20, 2024. The experimental group received an application-based health management program, while the control group did not. Results: The experimental group showed significant improvements in subjective quality of life, health-promoting behaviors, and subjective health status compared to the control group (p<.001). Conclusion: This study confirms that mobile applications can effectively manage health during andropause in middle-aged men. Further research with a larger sample size is recommended to validate these findings.

Purpose
Self-rated health in individuals with chronic diseases is influenced by various factors, including dietary adherence and physical activity. However, limited research has investigated how these factors relate to self-rated health among people with chronic kidney disease. Therefore, this study aimed to describe self-rated health and identify its associated factors in this population. Methods: This cross-sectional, secondary data analysis utilized datasets from the seventh Korea National Health and Nutrition Examination Survey, which were collected between 2016 and 2018. A total of 557 participants (mean age=74.8 years) with a glomerular filtration rate of <60 mL/min/1.73 m² were included. Data from health interviews and examinations were analyzed to assess self-rated health, dietary adherence, and physical activity. Descriptive and inferential statistical methods were employed for analysis. Results: Among the 557 participants, 42.6% rated their health as poor. Factors such as sex, age, income, smoking history, anxiety/depression, number of comorbidities, glomerular filtration rate, and physical activity were significantly associated with self-rated health. In contrast, dietary adherence did not exhibit a significant association. Conclusion: Understanding the factors associated with self-rated health can inform the development of nursing interventions aimed at improving self-rated health among patients with chronic kidney disease.

Purpose
This study aimed to examine the relationships among death anxiety, attitudes toward death, and burnout in nurses working in hemodialysis units. Methods: A cross-sectional, self-report questionnaire-based survey was conducted. Eighty-six nurses, each with more than one year of experience in hemodialysis units across six general hospitals, participated. Data were collected from July to December 2021. Statistical analyses included Pearson correlation coefficients and multivariate linear regression. Results: The mean death anxiety score was 2.71±0.73 out of 5. Among attitudes toward death, neutral acceptance was most prevalent, with a mean score of 5.48±1.07 out of 7. The average burnout score was 3.94±0.77 out of 7. Death anxiety showed a significant negative correlation with neutral acceptance of death (r=–.33, p=.002) and a significant positive correlation with fear of death attitudes (r=.65, p<.001). Multiple regression analysis identified marital status (being married) (β=–.35, p=.005) and the death attitude of escape acceptance (β=.37, p=.002) as significant predictors of burnout, together explaining 22.3% of the variance (F=2.43, p=.005). Conclusion: Attitudes toward death among hemodialysis nurses may be linked to burnout. Burnout management programs for nurses in hemodialysis units should provide opportunities for neutral discussions and emotional expression regarding death, and should address strategies to mitigate escape acceptance attitudes.

Purpose
The incidence of gynecological cancers is increasing, presenting significant challenges for patient care and outcomes. Perceived stress and negative affect can impede self-care behaviors and reduce health-related quality of life (HRQoL). This study examined the mediating effects of negative affect and cancer coping on the relationship between perceived hospital stress and HRQoL among patients with gynecological cancer. Methods: A cross-sectional mediation analysis was conducted with 118 gynecological cancer patients recruited from the outpatient clinic of a university hospital (October 2023 to February 2024). Participants completed validated instruments assessing perceived stress, negative affect, cancer coping, and HRQoL. Data were analyzed using Spearman’s correlations and the PROCESS macro (Model 4) with 95% bootstrap confidence intervals (CIs). Results: Perceived stress was significantly correlated with negative affect (r=.58, p<.001), cancer coping (r=.23, p=.012), and HRQoL (r=–.45, p<.001). Negative affect was correlated with HRQoL (r=–.59, p<.001). Furthermore, negative affect and cancer coping mediated the relationship between stress and HRQoL (B=–0.18, 95% CI=–0.27 to –0.11 and B=0.04, 95% CI=0.01 to 0.08, respectively). Conclusion: Negative affect and cancer coping significantly mediated the relationship between hospital stress and HRQoL. Targeted interventions aiming to reduce stress and strengthen emotional and coping strategies could enhance HRQoL among gynecological cancer patients.

Purpose
The purpose of this study was to examine the experiences of nurse managers in clinical nursing education during an emerging infectious disease outbreak. Methods: Individual semi-structured interviews were conducted with 12 nurse managers from seven general or tertiary hospitals, each with 300 or more beds, in South Korea. Data were collected between February 17 and June 10, 2023, and analyzed using qualitative content analysis. Results: Four themes and 11 subthemes were identified. Nurse managers faced significant challenges in departmental management during the infectious disease outbreak, encountered a wide range of student attitudes toward learning, adapted their teaching methods flexibly in response to changing infectious disease conditions, and ultimately found meaning in the irreplaceable value of clinical practice education. Conclusion: During the emerging infectious disease outbreak, nurse managers not only encountered substantial difficulties but also experienced professional growth as clinical nursing educators. To enhance clinical nursing education in such challenging environments, it is essential to minimize uncertainty caused by infectious diseases and foster positive perceptions among nursing students regarding clinical practice education under restrictive circumstances. Institutional support is also necessary to reduce the work burden on nurse managers.

Purpose
This study aimed to identify sex-specific predictors of microalbuminuria in patients with type 2 diabetes mellitus. Recognizing sex-based differences in risk factors may facilitate the early detection and prevention of diabetic kidney disease. Methods: A cross-sectional analysis was performed using data from the Korea National Health and Nutrition Examination Survey. Microalbuminuria was defined as a urinary albumin-to-creatinine ratio ≥30 mg/g. Multivariable complex sample logistic regression analyses were conducted separately for male and female. Independent variables included age, duration of diabetes, glycated hemoglobin (HbA1c), fasting blood sugar (FBS), triglyceride to high-density lipoprotein cholesterol ratio (TG/HDL-C), TG, HDL-C, waist circumference, and systolic blood pressure (SBP). Results: The prevalence of microalbuminuria was higher in male than in female. In both sexes, longer diabetes duration and elevated SBP were associated with microalbuminuria. Among male, FBS, TG/HDL-C ratio, TG, and low HDL-C were significant predictors. In female, HbA1c showed the strongest association, followed by age and diabetes duration. Conclusion: Sex-specific differences were identified in the predictors of microalbuminuria among patients with type 2 diabetes. Incorporating these differences into early screening and individualized care strategies may help improve the prevention of diabetic kidney complications.

Purpose
Emerging evidence indicates that eating patterns—particularly skipping meals and eating alone—are associated with excess body weight. However, few studies have assessed whether these behaviors contribute to weight gain across different age groups. This study examined the associations of skipping breakfast or dinner, and of eating those meals alone, with overweight or obesity among Korean adults compared to children and adolescents. Methods: This cross-sectional secondary analysis used data from the 2019 Korea National Health and Nutrition Examination Survey. Information on skipping meals, eating alone, and sociodemographic characteristics was obtained via self-report for adults and proxy report for participants under 12 years of age. Overweight or obesity was determined from measured height and weight. Multivariable logistic regression analyses were performed separately by age group. Results: Among adults, eating dinner alone was associated with higher odds of obesity (odds ratio [OR]=1.27, 95% confidence interval [CI]=1.06–1.52). Among adolescents, skipping dinner three or more times per week was associated with higher odds of obesity (OR=2.60, 95% CI=1.04–6.54). No significant associations were observed in children. Skipping breakfast or eating breakfast alone was not significantly associated with overweight or obesity in any age group. Conclusion: Although the cross-sectional design precludes causal inference, the findings suggest age-specific links between eating behaviors and weight status. For adults, reducing solitary dinners may help prevent obesity, whereas for adolescents, preventing frequent dinner skipping could be beneficial. Nursing strategies promoting shared mealtimes in adults and regular dinners in adolescents may help address obesity in Korea.

Purpose
This study developed a self-management program for patients undergoing lumbar spinal stenosis surgery utilizing the information-motivation-behavioral skills (IMB) model. Methods: This study employed a quasi-experimental design with a nonequivalent control group and pretest–posttest design. Data were collected from August 11, 2022, to March 31, 2023, at a general hospital in South Korea. A total of 58 patients participated in the study (30 experimental, 28 control group). The experimental group received a six-session self-management program based on the IBM model, whereas the control group received usual education and information. Data were analyzed with SPSS/WIN 23.0 using the independent t-test, chi-square test, Fisher’s exact test, Shapiro-Wilk test, and Mann-Whitney U test. Results: Significant differences were observed in self-management information (p<.001), personal motivation (p=.002), social motivation (p=.002), behavioral skills (p=.002), behaviors (p=.003), health-related quality of life (p<.001), and disc height (p=.006) in the experimental group following program implementation, compared to the control group. However, no significant differences were found in lower extremity muscular strength, lumbar lordotic angle, or the visual analog scores for low back pain and leg pain between the two groups. Conclusion: The self-management program developed in this study, based on the IMB model, was effective in improving self-management information, motivation, behavioral skills, behaviors, health-related quality of life, and self-management health outcomes in patients undergoing lumbar spinal stenosis surgery. Nevertheless, future research should aim to verify the long-term effects of such self-management programs by extending the intervention period.

Purpose
This study examined the effects of cognitive function, health literacy, and social support influence the risk of self-care non-adherence among older adults with chronic kidney disease. Methods: A cross-sectional survey was conducted using structured questionnaires. The study included 105 older adults (≥65 years) in the pre-dialysis stage, all of whom were receiving regular follow-up at a nephrology outpatient clinic in Jeonju, Jeollabuk-do, Korea. Data were collected through one-on-one interviews from April to May 2024 and analyzed using SPSS version 26.0. Predictive factors were assessed using hierarchical multiple regression analysis. Results: The risk of self-care non-adherence was significantly correlated with cognitive impairment (r=.61, p<.001), lower social support from healthcare providers (r=–.36, p<.001), and reduced health literacy (r=–.42, p<.001). Multiple regression analysis indicated that decreased physical activity (β=.25, p=.002), greater cognitive impairment (β=.29, p<.001), and lower support from healthcare providers (β=–.26, p=.008) were significant predictors of increased risk of self-care non-adherence. The model explained 46% of the variance in the risk of self-care non-adherence. In contrast, family support and health literacy were not significant predictors. Conclusion: To reduce the risk of self-care non-adherence in older adults with chronic kidney disease, routine cognitive screening and tailored education for those with cognitive impairment should be implemented in outpatient care. Promoting physical activity and strengthening support from healthcare providers are also key strategies to improve adherence in this population.

Purpose
Colorectal cancer (CRC) survivors face significant challenges after completing treatment, including returning to work, concerns about the future, and financial difficulties. Understanding how inner strength developed after treatment affects survivors’ lives is crucial for informing patient-centered care. This study explored the unique inner strength exhibited by CRC survivors during their transition to a “new normal.” Methods: We recruited 16 patients from Korea who had completed treatment, to explore their experiences of managing their health. We conducted a qualitative study from July 4, 2022 to July 25, 2022 using individual interviews and directed content analysis. Transcribed interview data were analyzed to interpret meaning from the data, consistent with the naturalistic paradigm. Results: Participants described their transition to a new normal by reframing the cancer experience, struggling to return to normal life, experiencing growth promoted by supportive relationships, and encountering both positive and negative life changes. Throughout these experiences as survivors, inner strength played a critical role in adapting to a new normal. Conclusion: Our findings suggest that inner strength serves as a dynamic psychological resource, enabling CRC survivors to reframe their illness, regain disrupted roles, and reconstruct a meaningful life despite ongoing physical and emotional challenges. In doing so, inner strength facilitates their adaptation to a new normal.

Purpose
Person-centered care is essential to improving patient outcomes, yet the factors that influence it require further investigation. This study examines the relationships among nurses’ compassion competence, cultural competence, intercultural communication skills, and person-centered care, and it identifies key predictors of person-centered care. Methods: A descriptive survey was conducted among 191 nurses from two general hospitals using convenience sampling between April 1 and April 22, 2024. Data collection included measures of compassion competence, cultural competence, intercultural communication skills, and person-centered care. Statistical analyses involved descriptive statistics, the independent t-test, analysis of variance, Pearson’s correlation coefficient, and stepwise multiple regression. Results: Of the 191 participants, 172 (90.1%) were females and 19 (9.9%) were males, with an average clinical experience of 8.89 years. Person-centered care showed significant positive correlations with compassion competence (r=.58, p<.001), cultural competence (r=.62, p<.001), and intercultural communication skills (r=.63, p<.001). Key predictors of person-centered care included intercultural communication skills (β=.29, p=.001), compassion competence (β=.27, p<.001), cultural competence (β=.20, p=.024), and non-shift work status (β=.12, p=.031). The model explained 47.9% of the variance in person-centered care (F=44.76, p<.001). Conclusion: In this study, person-centered care among nurses was influenced by compassion competence, cultural competence, intercultural communication skills, and work type. Further research is warranted on the delivery of person-centered care among nurses who provide care to patients from diverse cultural backgrounds.
