Purpose: Nursing students are future healthcare workers responsible for maintaining public health. Owing to the increase in early resignation among new nurses, nursing education outcomes must be evaluated by investigating students' practice readiness. Methods: Using convenience sampling, we recruited fourth-year students from two nursing colleges to participate in a cross-sectional online survey in November 2023. The Casey-Fink Readiness for Practice Survey was used to assess practice readiness and the data were analyzed using descriptive statistics, independent t-tests, and ANOVA. Results: Among the 157 participants (female, 77.7%; mean age, 23.12±1.93 yrs), the overall practice readiness score was 63.53±8.30 (range: 20~80) and the mean subscale score was 23.14±3.73 for clinical problem-solving (range: 7~28), 6.69±1.25 for learning techniques (range: 2~8), 16.87±2.46 for professional identity (range: 5~20), and 16.82±3.46 for trials and tribulations (range: 6~24). Practice readiness did not differ significantly by gender or age and was greater among subgroups with high grades and satisfaction with the major, classroom practice, simulation practice, clinical practice, and lectures. Conclusion Universities must improve the quality of classes and practical education to enhance fourth-year nursing students’ practice readiness.Nursing education programs incorporating problem-based learning must be developed and evaluated to strengthen students’ clinical inference and critical-thinking skills.

Purpose: This study aimed to identify the effects of shared leadership, communication skills, and team effectiveness, as perceived by nurses and nursing assistants in comprehensive nursing service units. Methods: A cross-sectional research design was adopted, and the sample included 306 nurses, nurse assistants, and caregivers working in nine hospitals with fewer than 500 beds in two South Korean cities. The data were analyzed using descriptive statistics, t-tests, ANOVA, Pearson’s correlation coefficient, and four-step hierarchical regression analysis. Results: The factors influencing team effectiveness in the hierarchal multiple regression analysis were shared leadership (β=.57,p<.001) and communication skills (β=.18, p<.001). These factors explained 49% of the total variance. Conclusion To enhance team effectiveness in compressive nursing service units, educational programs focusing on shared leadership and communication skills among nurses, nursing assistants, and caregivers must be developed.

Purpose: This study aimed to identify core domains for pre-registered nurses by comparing licensing competencies with program outcomes (POs) in undergraduate nursing education. This was accomplished in preparation for the transition of the Korean Nurse Licensing Examination (KNLE) from a tradition seven-subject format to a newly integrated, competency-based single-subject format that reflects current trends in nursing assessment. Methods: A literature review and survey were conducted. From 828 studies retrieved via PubMed, CINAHL, and Google Scholar using keywords such as “newly graduated registered nurses” and “competency OR competence,” 18 were selected according to pre-established inclusion and exclusion criteria. Documents from national and international nursing organizations were included to extract relevant licensing competencies. We also reviewed POs from all undergraduate nursing schools in South Korea to align educational outcomes with the identified core domains. Results: The core domains identified were clinical performance and decision-making, professional attitudes and ethics, communication and interpersonal skills, leadership and teamwork, quality improvement and safety, health promotion and prevention, and information technology and digital health. These domains showed strong alignment with POs under the fourth-cycle accreditation standards. Conclusion It concludes the seven core domains will be appropriate for evaluating pre-registered nurses in the integrated KNLE. Based on the seven identified core domains, expert consensus should be sought in the next phase to support the development of integrated, competency-based test items grounded in these domains.

Objectives: To investigate the relationship between self-rating of subjective oral health, oral hygiene behaviors, and objective oral health status, and to identify factors that determine self-rating for subjective oral health. Methods: This retrospective study examined data from 1,128 patients who underwent panoramic radiography and oral examination based on national health checkups between 2009 and 2015. Oral hygiene behavior was validated using a questionnaire, and the presence of oral diseases was validated through oral examination and panoramic radiographs. The effect of oral hygiene behaviors on the presence of oral diseases or dental treatment was evaluated using univariate regression analysis. Oral hygiene behaviors and the prevalence of oral disease were compared, according to selfrated subjective oral health, using the chi-square test. Factors affecting self-rating of subjective oral health were determined using multivariate regression analysis. Results: Patients who brushed their teeth less than three times per day had a higher risk of dental caries, periodontitis, and missing teeth (P<0.05). The percentage of patients performing oral hygiene behaviors differed significantly according to the self-rating of subjective oral health. The factors affecting the self-rating of subjective oral health were pain and the presence of restored teeth.The presence of gingivitis, periodontitis, and the number of dental caries had no significant effect on the self-rating of oral health. Conclusions Self-rating of oral health was determined by treatment experience rather than objective oral health status and it affected oral hygiene behavior.

This study aimed to establish infection control strategies for preventing the spread of scabies within a single institution by analyzing the epidemiological characteristics of patients diagnosed with scabies. Methods: This was a retrospective descriptive study. The electronic medical records of 430 patients diagnosed with scabies at the dermatology outpatient department of Uijeongbu St. Mary’s Hospital from January 2020 to December 2022 were used to collect data on their characteristics. The subjects were divided into three groups: patients, family of confirmed patients, and healthcare workers. General and epidemiological characteristics were analyzed. Results: The average age was 60.89 ± 22.39 years. The number of days from symptom onset to diagnosis was unknown in many cases (65.3%), although the average was 63.42 ± 64.18 days. Repeated visits after treatment were observed in 193 patients (67.5%), 38 family members of confirmed patients (55.1%), and 35 healthcare workers (46.7%), showing a statistically significant difference (p = .002). The most common place of residence before the visit was home (56.2%), and the most common suspected origin of contagion was the home (38.3%), and the most common category of the suspected contagious person was family (49.6%). Conclusion: Cases of scabies were disproportionately common in women and older adults. The interval from symptom onset to diagnosis was long, and about half of the cases involved itching but no skin lesions. More than one-thirds of cases did not revisit for a follow-up after 2 weeks. In the overall results, unlike previous studies, factors related to home and family were frequently observed as epidemiological characteristics.

Purpose: Obesity is a well-established risk factor for dyslipidemia. Normal-weight obesity (NWO) is associated with lipid profile abnormalities. However, research in Korea on the relationship between NWO and dyslipidemia is limited. Therefore, this study evaluated the relationship between obesity types, including NWO, and dyslipidemia, and investigated these relationships by age and sex. Methods: Secondary data analysis was performed using data from the 9th Korea National Health and Nutrition Examination Survey conducted in 2022. In total, 3,805 participants were analyzed using complex sample multiple logistic regression based on body mass index and body fat percentage (BF%). Results: NWO was significantly associated with an increased risk of dyslipidemia relative to normal weight non-obesity (odds ratio: 1.66, 95% confidence interval: 1.34~2.06). Notably, individuals with NWO under the age of 65 and men had a higher risk of dyslipidemia, underscoring the importance of targeted health management in these populations. Conclusion NWO was positively correlated with dyslipidemia. Therefore, the role of clinical nurses in early screening for NWO is of considerable importance, particularly among high-risk populations such as men under the age of 65. To support obesity management and the prevention of dyslipidemia, nursing interventions aimed at reducing BF% by promoting lifestyle modifications and regular monitoring are essential.

Background: Prevention of contrast-induced nephropathy (CIN) is crucial in acute myocardial infarction (AMI) patients undergoing coronary interventions. Previous studies suggest that high-dose statins may aid in CIN prevention, yet comparative studies among different statin types using cystatin C (cysC) as a biomarker for CIN are absent. This study evaluated the effectiveness of high-dose rosuvastatin versus atorvastatin in preventing cysC-based CIN (cysC-CIN) in AMI patients. Methods: This multicenter registry included 431 patients (rosuvastatin 20 mg: n = 231, atorvastatin 40 mg: n = 200). The primary endpoint was cysC-CIN incidence within 48 hours post contrast; the secondary endpoints were creatinine-based CIN (cr-CIN) incidence within 72 hours post contrast and post 30 days adverse events. Results: The incidences of cysC-CIN (12.1% vs. 7.5%, P = 0.103) and cr-CIN (6.2% vs. 3.5%, P = 0.103) were higher in the atorvastatin group without significant statistical differences.Multivariable regression analysis, which was adjusted for CIN risk factors and the variables with univariate association, showed no increased odds ratio (OR) (OR, 2.185; 95% confidence interval [CI], 0.899, 5.315; P = 0.085) for cysC-CIN in the atorvastatin group compared to the rosuvastatin group. However, statin-naïve atorvastatin subgroup had significantly increased odds of cysC-CIN compared to the rosuvastatin group (OR, 2.977; 95% CI, 1.057, 8.378; P = 0.039). At post 30 days renal, cardiovascular, and mortality event rates were both low and similar between the two groups. Conclusion No significant difference in cysC-CIN incidence was found between the highdose rosuvastatin and atorvastatin groups in AMI patients and cysC was more sensitive to the early detection of CIN than creatinine.

Background: Healthcare-associated infections impose a significant burden on antibiotic usage, healthcare expenditures, and morbidity. Therefore, it is crucial to revise policies to minimize such losses. This nationwide survey aimed to evaluate infection prevention and control (IPC) components in healthcare facilities and encourage improvements in acute care hospitals with inadequate infection prevention settings. This study aims to enhance the infection control capabilities of healthcare facilities. Methods: From December 27, 2021, to May 13, 2022, we conducted a survey of 1,767 acute care hospitals in the Republic of Korea. A survey was conducted to evaluate the infection control components in 1,767 acute care hospitals. Infection control officers provided direct responses to a systematically developed questionnaire. Subsequently, 10% of the respondents were randomly selected for the site investigation. Results: Overall, 1,197 (67.7%) hospitals responded to the online survey. On-site investigations were conducted at 125 hospitals. Hospitals with ≥ 150 beds are advised to have an IPC team under Article 3 of the Medical Service Act; however, only 87.0% (598/687) of hospitals with ≥ 100 beds had one. Conversely, 22.7% (116/510) of hospitals with < 100 beds had an IPC team. Regulations for hand hygiene, waste management, healthcare worker protection and safety, environmental cleaning, standard precautions, and prevention of the transmission of multidrug-resistant pathogens were present in 84.2%, 80.1%, 77.4%, 76.2%, 75.8%, and 63.5% of the hospitals, respectively. Hospitals with < 100 beds had low availability of all categories of standard operating procedures. Conclusion This study is the first national survey of acute care hospitals in the Republic of Korea. The data presented in the current study will improve the understanding of IPC status and will help establish a survey system. Our survey provides a basis for improving policies related to IPC in healthcare facilities.

Background: An ideal lung allocation system should reduce waiting list deaths, improve transplant survival, and ensure equitable organ allocation. This study aimed to develop a novel lung allocation score (LAS) system, the MaxBenefit LAS, to maximize transplant benefits. Methods: This study retrospectively analyzed data from the Korean Network for Organ Sharing database, including 1,599 lung transplant candidates between September 2009 and December 2020. We developed the MaxBenefit LAS, combining a waitlist mortality model and a post-transplant survival model using elastic-net Cox regression, was assessed using area under the curve (AUC) values and Uno’s C-index. Its performance was compared to the US LAS in an independent cohort. Results: The waitlist mortality model showed strong predictive performance with AUC values of 0.834 and 0.818 in the training and validation cohorts, respectively. The post-transplant survival model also demonstrated good predictive ability (AUC: 0.708 and 0.685). The MaxBenefit LAS effectively stratified patients by risk, with higher scores correlating with increased waitlist mortality and decreased post-transplant mortality. The MaxBenefit LAS outperformed the conventional LAS in predicting waitlist death and identifying candidates with higher transplant benefits. Conclusion The MaxBenefit LAS offers a promising approach to optimizing lung allocation by balancing the urgency of candidates with their likelihood of survival post-transplant. This novel system has the potential to improve outcomes for lung transplant recipients and reduce waitlist mortality, providing a more equitable allocation of donor lungs.

Background: While the clinical course of radiation-induced meningioma (RIM) is considered to be more aggressive than that of sporadic meningioma (SM), the genetic predisposition for RIM is not established well. The present study aimed to analyze the clinical and genetic characteristics of RIMs to increase understanding of the tumorigenesis and prognosis of RIMs. Methods: We investigated a database of 24 patients who met the RIM criteria between January 2000 and April 2023. Genetic analysis through next-generation sequencing with a targeted gene panel was performed on 10 RIM samples. Clinical, radiological, and pathological parameters were evaluated with genetic analyses. Results: The median ages for receiving radiotherapy (RT) and RIM diagnosis were 8.0 and 27.5 years, respectively, with an interval of 17.5 years between RT and RIM diagnosis. RIMs tended to develop in non-skull bases and multifocal locations. Most primary pathologies included germ cell tumors and medulloblastoma. The tumor growth rate was 3.83 cm 3 per year, and the median doubling time was 0.8 years. All patients underwent surgical resection of RIMs. The histological grade of RIMs was World Health Organization grade 1 (64%) or 2 (36%). RIMs showed higher incidences in young-age (63%), high-dose (75%), and extendedfield (79%) RT groups. The recurrence rate was 21%. Genetic analysis revealed NF2 one copy loss in 90% of the patients, with truncating NF2 mutations and additional copy number aberrations in grade 2 RIMs. TERT promoter mutation and CDKN2A/B deletion were not identified. Notably, loss of H3K27me3 was identified in 26% of RIMs. H3K27me3 loss was associated with a higher prevalence of grade 2 RIMs (67%) and high recurrence rates (33%). Conclusion The study reveals a higher prevalence of high-grade tumors among RIMs with more rapid growth and higher recurrences than SMs. Genetically, RIMs are primarily associated with NF-2 alterations with chromosomal abnormalities in grade 2 tumors, along with a higher proportion of H3K27me3 loss.
