Purpose : The purpose of this study was to validate the Korean version of Partners In Health scale (PIH-K) which is used to measure the self-management of patients with chronic illnesses in Korea. Methods : Translation of the 12-item PIH-K was conducted according to the World Health Organization guidelines. Data from 306 participants who took medicines over 3 months by doctor's prescription were collected from October to November 2017. Validity such as content validity, construct validity, and concurrent validity were conducted using content validity index (CVI), exploratory and confirmatory factor analyses (CFA). To evaluate concurrent validity, the correlation coefficients between the PIH-K and concurrent scales (Self-As-Carer Inventory) were calculated. The reliability of the PIH-K was examined using the internal consistency and test-retest reliability tests. Results : The CVI of the PIH-K was 0.91. According to the CFA, factor loadings for four factors ranged from .64 to .97, which explained 67.5% of the total variance. The PIH-K was significantly correlated with concurrent variables such as those on the Self-As-Carer Inventory. The Cronbach's ${\alpha}$ was .86 and the intraclass correlation coefficient for the two-week test-retest reliability was .88. Conclusion : Findings show that the PIH-K is reliable and valid in measuring self-management of patients with chronic illnesses.

Purpose : The purpose of this study was to identify factors influencing the professional self-concept of nurses working in intensive care units (ICUs). Methods : Data were collected from July 1 to August 15, 2014. The subjects were 206 ICU nurses working in four university hospitals in B and U cities, Korea. Their professional self-concept was measured using Arthur's Scale revised by Yoon (2012), and professional quality of life (QOL) was measured using Pro QOL Korean Ver. 5 developed by Stamm (2010). Data were analyzed with SPSS Ver. 18, using a t-test, ANOVA, Pearson's correlation coefficient, and multiple regression analysis. Results : Professional self-concept was significantly correlated with compassion satisfaction (r=.61, p<.001), and burn out (r=-.57, p<.001). The factors influencing professional self-concept were compassion satisfaction (${\beta}=.46$, p<.001), burn out (${\beta}=-.27$, p<.001), and education level (${\beta}=.14$, p =.014). The explanatory power of this model was 46.5%. Conclusion : The results suggest that the influencing factors found in this study should be considered when planning nursing intervention programs for improving the professional self-concept of ICU nurses.

Purpose : The aims of this study were to identify the incidence of pressure ulcers and to compare the predictive validities of pressure ulcer risk assessment scales among trauma patients. Methods : This was a prospective observational study. A total of 155 patients admitted to a trauma intensive care unit in a university hospital were enrolled. The predictive validity of the Braden, Cubbin & Jackson, and Waterlow scales were assessed based on the sensitivity, specificity, positive and negative predictive values, and area under the receiver operating characteristic curve (AUC). Results : Of the patients, 14 (9.0%) subsequently developed pressure ulcers. The sensitivity, specificity, positive predictive values, and negative predictive values were 78.6%, 75.9%, 24.4%, and 97.3%, respectively, for the Braden scale (cut-off point of 12); 85.7%, 68.8%, 21.4%, and 98.0%, respectively, for the Cubbin & Jackson scale (cut-off point of 26); and 71.4%, 87.2%, 35.7%, and 96.9%, respectively, for the Waterlow scale (cut-off point of 18). The AUCs were 0.88 (Waterlow), 0.86 (Braden), and 0.85 (Cubbin & Jackson). Conclusion : The findings indicate that the predictive validity values of the Waterlow, Braden, and Cubbin & Jackson scales were similarly high. However, further studies need to also consider clinical usefulness of the scales.

Purpose : The purpose of this study was to identify the extent to which intensive care unit (ICU) nurses' perceptions of life-sustaining treatment decisions and "a good death" affect attitudes toward terminal care. Method : Participants included 109 ICU nurses from three university hospitals. Data were collected using structured questionnaires, and collected data were analyzed using a t-test, ANOVA, the $Scheff{\acute{e}}$ test, Pearson correlation coefficients, and a multiple regression analysis (SPSS 24.0 program). Results : Perceptions of life-sustaining treatment decisions and a sense of closeness (a constituent for the awareness of "a good death") were positively correlated with terminal care attitudes. The factors affecting terminal care attitudes were a clinical career in ICU (${\beta}=.20$, p =.035), a sense of closeness(${\beta}=.19$, p =.041), and the perception of a life-sustaining treatment decision (${\beta}=.22$, p =.017). This finding indicates that more than 10 years of experience in ICU, a greater sense of closeness, and a higher view of life-sustaining treatment decisions results in more positive attitudes toward terminal care. The explanatory power of these variables on terminal care attitudes was 14% (F=6.84, p < .001, Adj $R^2=.140$). Conclusion : A sense of closeness and the perception of life-sustaining treatment decisions were identified as the factors affecting terminal care attitudes. Thus, various programs must be developed to raise awareness among ICU nurses of "a good death" and perceptions of life-sustaining treatment decisions.

Purpose : The purpose of this study was to identify the attributes, antecedents, and consequences of the transition of simulation-based learning (SBL) in nursing schools. Methods : The study was conducted in accordance with Walker and Avant's conceptual analysis process. We searched MEDLINE, CINAHL, EMBASE, Google Scholar, and RISS (Korean Education and Research Information Service) databases, resulting in nine studies for an in-depth review. Results : The attributes of transition of SBL include (1) preparing for a professional role, (2) practicing in a real clinical setting, and (3) progressing toward expected competency. Antecedents of the concept include novice status, changing roles, clinical experience in controlled settings, and expected competency in the clinical setting. Conclusion : The transition of SBL includes the important feature of progression toward expected competency. Further research is needed to identify graduate nurses' experiences during this transition to establish a strategy for improving it and developing a measurement tool that reflects attributes of the concept.

Purpose : The aim of this study was to explore the attributes, antecedents, and consequences of patient-centered care (PCC) for older adults with multimorbidity in acute care hospitals. Methods : The concept analysis performed by Walker and Avant was used to analyze PCC. Fifteen studies from the literature related to PCC appear in systematic literature reviews in the fields of theology, medicine, psychology, and nursing. Results : PCC in acute care hospitals was defined according to the five attributes of 'maintaining patient autonomy', 'empowering self-care', 'individualized and relationship-based care', 'shared decision-making', and 'creating a homelike environment'. Antecedents of PCC were found to be a respect for patients' preferences, qualifications of the nursing staff, care coordination and integration, and organizational support. Consequences of effective PCC were a functional status; health-related quality of life; satisfaction with care, mortality, and medical costs from the perspective of the patient and family; and quality of care and therapeutic relationships from nurses' viewpoints. Conclusion : PCC as defined by the results of this study will contribute to the foundation of institutionalization and the creation of a safe and healthy acute care hospital culture focused on patients' preferences and values.

Purpose : The purpose of this study was to investigate the effect of the perceived nursing work environment (NWE) on person-centered critical care nursing (PCCN) practices among nurses in intensive care units (ICUs). Methods : A cross-sectional research design was adopted for this study; participants were 126 ICU nurses working in five hospitals in B city. From December 2018 to February 2019, a survey questionnaire on NWE and PCCN were conducted. The collected data were analyzed with a multiple hierarchical regression analysis. Results : The mean score for NWE was $2.98{\pm}0.39$. Among the factors, basic work system was the highest ($3.39{\pm}0.41$), followed by leadership of the head nurse ($3.31{\pm}0.55$), interpersonal relationships ($2.77{\pm}0.62$), and institutional support ($2.58{\pm}0.52$). The mean score for PCCN was $3.52{\pm}0.46$. Among the factors, comfort was the highest ($3.77{\pm}0.62$), followed by respect ($3.55{\pm}0.56$), compassion ($3.43{\pm}0.60$), and individuality ($3.38{\pm}0.56$). The interpersonal relationship (${\beta}=.31$, p=.001) and the number of patients per shift (${\beta}=-.23$, p=.005) had a significant effect on PCCN, accounting for 25.9% of the total variance. Conclusion : These results suggest that it is necessary to enhance the relationship-oriented culture and reduce the workload of nurses in order to improve the quality of nursing care in ICUs.

Purpose : The purpose of this study was to examine the mediating effect of perceptions regarding the importance of patient safety management in the relationship between incident reporting attitudes and patient safety care activities for nurses in small-and medium-sized general hospitals. The objective was to provide a basis for planning tailored training programs aimed at improving patient safety care activities. Methods : This study was conducted with 187 participants in small- and medium-sized general hospitals in K city in South Korea from March 15 to March 31, 2019. The data collected from participants were analyzed using descriptive statistics, a t-test, ANOVA, Pearson's correlation coefficients, and a multiple regression using IBM SPSS/WIN 21.0 software. Results : Patient safety care activities were found to be correlated with incident reporting attitudes (r=.27, p < .001) and perceptions of the importance of patient safety management (r=.59, p < .001). Further, perceptions of the importance of patient safety management had a complete mediating effect (${\beta}=.409$, p < .001) on the relationship between incident reporting attitudes and patient safety care activities. Conclusion : Based on the findings of this study, tailored training programs regarding patient safety care activities focused on boosting perceptions of the importance of patient safety management are highly recommended to improve nurses' patient safety care activities in small- and medium-sized general hospitals.
