Objective: The Korean Triage and Acuity Scale (KTAS) is a triage tool for patients in the emergency department (ED). This study aimed to evaluate the ability of the KTAS to predict poor outcomes in South Korean ED patients with a suspected infection. We also compared the effectiveness of KTAS with that of the National Early Warning Score (NEWS) and Modified Early Warning Score (MEWS) in predicting poor outcomes. Methods: We conducted a single-center retrospective study that included adult patients with a suspected infection who were admitted to the ED between January 2019 and December 2019. Patients who received a prescription for antibiotics and associated culture tests in the ED were considered to have an infection. Poor outcomes were evaluated by in-hospital mortality, general ward admission, and intensive care unit (ICU) admission. A receiver operating characteristics (ROC) curve analysis was performed to evaluate and compare KTAS, NEWS, and MEWS. Results: Of the 4,127 patients in the study, in-hospital mortality was reported in 154 (3.7%) patients. The median KTAS was lower in the non-survivors than in the survivors (2.51 vs. 3.35). Multivariate logistic regression analysis showed that the KTAS was associated with in-hospital mortality, ward admission, and ICU admission. The area under the ROC curve (AUROC) values for predicting in-hospital mortality associated with the KTAS, NEWS, and MEWS were 0.776 (95% confidence interval, 0.747-0.803), 0.829 (0.759-0.811) and 0.739 (0.694-0.786), respectively. Conclusion Our results showed that the KTAS was associated with in-hospital mortality, ward admissions, and ICU admissions among ED patients with a suspected infection. Thus, KTAS may be reliable in predicting a poor outcome in ED patients with a suspected infection.

Purpose: The purpose of this study is to understand the actual status of fundamentals of nursing practice (FNP) education at nursing colleges, and the difficulties of FNP operation in the early stages of the COVID-19. Methods: This study used a descriptive design. Data collection was conducted from December 9, 2020 to January 31, 2021 using the self-report questionnaire method for a total of 95 nursing colleges. The questionnaire consisted of characteristics related to FNP, changes in FNP education, difficulties in operating FNP, and countermeasures in the COVID-19 situation. Results: Changes in FNP due to COVID-19 were distribution of practice places, reduction of the number of students, short-term intensive classes, and reduction of face-to-face practice. Most colleges conducted FNP face-to-face, but some schools showed that FNP was conducted non-face-to-face. The difficulties of operating FNP that instructors experienced induced concerns about a decrease in student competency due to lack of face-to-face practice and an unofficial increase in the number of teaching hours and physical demands on instructors due to the expansion of the division. Conclusion In order to develop the capabilities of nursing students in other pandemic situations in the future, it is necessary to find systematic coping strategy to reduce the burden of FNP instructors, and to develop non-face-to-face online practice contents and consumables for online practice.

Purpose: This study was done to investigate the experience of physical and emotional safety in nursing students during fundamentals of nursing practicum. Methods: A descriptive cross-sectional study was conducted from March to September 2019. A total of 553 nursing students, who had completed fundamental nursing laboratories, participated in this study. Data were collected using self-report questionnaires which included questions about general characteristics, physical and emotional safety during fundamental nursing laboratories along with an informed consent given prior to the practicum. Results: Of the students, 26 experienced physical safety accidents, and 18 reported emotional safety accidents. Students' mean stress score for physical safety was 1.95, and the mean score for emotional safety was 1.92. Of the students, more than 59.1% agreed to volunteer as practice models in certain nursing procedures’ training. Of the students, 55.8% were satisfied with using their bodies to train fundamental nursing skills. 61.8% of students reported that informed consent was obtained during the nursing laboratory, and 88.6% of students thought that informed consent needs to be obtained. Conclusion To prevent safety accidents during the fundamentals of nursing practicum and systematically manage accidents, standardized safety guidelines for nursing practicum should be developed. Establishing various training strategies using advanced models or simulators to increase education efficiency and satisfaction is necessary.

Purpose: The purposes of this study were to analyze and compare the textbooks of fundamentals of nursing and practice in order to standardize them for medication administration, infection control, and pressure injury. Methods: The current study is a literature review of the ten textbooks published after 2013. Ten textbooks were the ones selected by the Korea Health Personnel Licensing Examination Institute as major textbooks. Three items were reviewed: medication administration, infection control, and pressure injury, with a focus on differences in numbers, range, direction, and others. Results: For medication administration, there were some discrepancies in the size of needle and syringe, maximum dosage depending on injection methods, replacement period of catheter and infusion set, depth of insertion for vaginal medication administration. For infection control, items with discrepancies included length of time for hand washing, concentration of chemical sterilant, frequency of ventilation to prevent airborne disease, distance to prevent droplet-borne infection, the latent period of infectious disease, and methods to treat medical wastes. For pressure injury, the discrepancies were exhibited in the degree and duration of pressure for pressure injuries, range of scores for risks in pressure injury assessment tools, and temperature of the solution to irrigate pressure injuries. Conclusion Standardized textbooks for these three parts will be useful teaching aide for students and nurses to carry out consistent and professional nursing for patients’ safety.

Nociceptin/orphanin FQ (N/OFQ) and its receptor, nociceptin opioid peptide (NOP) receptor, are localized in brain areas implicated in depression including the amygdala, bed nucleus of the stria terminalis, habenula, and monoaminergic nuclei in the brain stem. N/OFQ inhibits neuronal excitability of monoaminergic neurons and monoamine release from their terminals by activation of G protein-coupled inwardly rectifying K⁺ channels and inhibition of voltage sensitive calcium channels, respectively. Therefore, NOP receptor antagonists have been proposed as a potential antidepressant. Indeed, mounting evidence shows that NOP receptor antagonists have antidepressant-like effects in various preclinical animal models of depression, and recent clinical studies again confirmed the idea that blockade of NOP receptor signaling could provide a novel strategy for the treatment of depression. In this review, we describe the pharmacological effects of N/OFQ in relation to depression and explore the possible mechanism of NOP receptor antagonists as potential antidepressants.

PURPOSE: This study aimed to validate the psychometric properties of the CRAFFT (Car, Relax, Alone, Forget, Family/Friends, Trouble) by using item response theory (IRT) and further examine gender differences in item-level responses.METHODS: This study used the 13(th) (2017) Korea Youth Risk Behavior Survey data conducted by the Korean Centers for Disease and Prevention and analyzed data of 8,568 students who reported drinking alcohol in the previous 30 days. IRT assumptions including unidimensionality, local independence, and monotonicity were tested. A one-factor two-parameter IRT model was fitted for item parameterization (M₂ = 76.92, 20 df, p < .001, root mean square error of approximation = 0.02). Graphics for item characteristic curves and item and test information curves were provided. Differential item functioning (DIF) analysis was evaluated to measure item equivalence between boys and girls.RESULTS: Unidimensionality and local independence were satisfied, and the dominant factor eigenvalue and variance were 2.48 and 41.3% in boys and 2.08 and 34.7% in girls, respectively, and residual correlations in paired items were less than .2. The discrimination parameters were estimated as 1.32–3.59 for boys and 1.30–3.64 for girls. The severity parameters estimated verity as −0.23 to 1.67 for boys and −0.32 to 2.17 for girls. DIF was detected for four of six items, “Car,” “Relax,” “Forget,” and “Family/friends.” However, its impact on the total score was negligible.CONCLUSION: The CRAFFT is a valid and reliable screening tool to identify alcohol use problems for both boys and girls, exhibiting good discrimination, good coverage of severity, and negligible DIF.

A menu labeling initiative is a lawful regulation with an aim to promote public health by providing customers the right to make informed menu choices. As college years are a critical period in which students form dietary habits, which are sustained throughout their lives, provision of nutritional information at the university dining services is important to students' health and life. Due to the lack of research on menu labeling at university dining services, the purpose of this study was to examine college students' attitudes and motivations toward menu labeling at university dining services, as well as their use intentions toward nutrition information at university dining services. Data were collected from a self-administered survey distributed to 484 college students who had experienced university dining services. Motivations of university students toward menu labeling were categorized into ‘knowledge pursuit’ and ‘health pursuit’. Students' attitudes toward menu labeling had a positive effect on their intention to use menu labeling at university dining services. The findings of the study indicated that female students, or those who frequently used nutrition information, tended to have higher attitudes, motivations, and use intentions toward nutrition information. The study results suggest that facilitation of healthy eating environments at university dining services by offering nutrition information, and nutrition and health education is necessary.

PURPOSE: This study was done to identify the influence of severity of drinking problem, circadian rhythm and sleep quality in patients with alcohol use. METHODS: A descriptive study design was utilized. Data were collected using self-report questionnaires from 139 patients with alcohol use disorder who were admitted to a psychiatric hospital in D city, Korea. The questionnaires included Alcohol Use Disorders Identification Test (AUDIT), Composite Scale of Morningness (CMS), Pittsburgh Sleep Quality Index (PSQI), and Korea sleep scale A. Data were analyzed using descriptive statistics, Pearson's correlation coefficients, and multiple regressions using the SPSS 20.0 program. RESULTS: There was significant correlations among severity of problem drinking, circadian rhythm, sleep quality and sleep disorder. The significant factors influencing sleep disorder were severity of problem drinking(β=.12, p=.042), circadian rhythm(β=−.14, p=.039) and sleep quality(β=.63, p=<.001). This model explained 56% of variance in sleep disorder(F=57.34, p=<.001). CONCLUSION: The results of this study suggest that the development of sleep intervention programs for alcohol use disorder patients needs to consider severity of alcohol use, circadian rhythm and sleep quality, and sleep assessment and intervention are needed the early stage of the treatment and recovery process.

PURPOSE: The aim of this study was to determine the relationship between the injury severity and pain intensity according to age in patients with extremity injuries. METHODS: Adult patients with an extremity injury who visited the emergency department (ED) from June 1, 2016 to November 31, 2016 were analyzed retrospectively. The major injury was defined as structural damage below the muscle layer, such as muscle, ligament, and bone. Minor injury group and major injury group were separated according to this definition. The relationship of age and pain score assessed with the numerical rating scale (NRS) with the injury severity was analyzed. RESULTS: Of a total of 1,441 patients, the number of patients with a minor and major injury was 854 (59.3%) and 587 (40.7%), respectively. The proportion of patients aged 65 and older was 6.1% and 25.7% in the minor and major injury group, respectively. Age and NRS scale showed significantly positive associations with the injury severity (p < 0.001). In all NRS scores, the overall proportion of major injuries in the older age group was higher than that in the younger age group. Regardless of the younger ( < 65 years) or older (≥65 years) age group, the NRS score was positively related to the injury severity (young age group [odds ratio, 3.944]; older age group [odds ratio, 5.754]). CONCLUSION: The pain intensity is positively related to the severity of injury regardless of age. The pain intensity is the important factor of a patient assessment and treatment in the emergency department.

PURPOSE: The purpose of this study was to evaluate the reliability and validity of the Korean version of Diabetes Empowerment Measurement Scale Short Form (DES-SF) for use with diabetic patients in Korea. METHODS: A cross-sectional descriptive study was used with 107 participants. Bilingual nursing professionals performed translation and reverse translation. Reliability and validity such as face validity, construct validity, and concurrent validity were conducted. To assess the concurrent validity, the correlation coefficients between the Korean version of the DES-SF and a concurrent scale (Diabetes Self-Efficacy Scale, DSES) were calculated. RESULTS: In the explanatory factor analysis, a uni-dimension was proposed, the one factor accounted for 49.4% of total variances. The Korean version of the DES-SF correlated with a concurrent variable such DSES for reliability of the Korean version of the DES-SF, Cronbach's α=.85. CONCLUSION: The findings show that the Korean version of the DES-SF is reliable and valid for evaluating empowerment in patients with diabetes in Korea.
