1.Task performance, task importance, and educational needs for novice-level nursing tasks as perceived by neonatal intensive care unit nurses with various levels of experience in South Korea: a cross-sectional study
Child Health Nursing Research 2026;32(1):80-92
Purpose:
This study aimed to identify differences in perceived task performance, task importance, and educational needs for novice-level tasks among neonatal intensive care unit (NICU) nurses with varying levels of clinical experience and to provide foundational data for developing systematic educational programs to strengthen the competencies of novice nurses.
Methods:
Participants were recruited from the NICUs of three hospitals—one university-affiliated hospital and two general hospitals located in B Metropolitan City, South Korea. Using convenience sampling, 116 staff nurses with at least 3 months of NICU experience were surveyed between March and November 2025. For comparative analysis, participants were divided into three career groups based on their NICU experience: <3 years, 3–9 years, and ≥9 years. Data were analyzed using descriptive statistics, analysis of variance, and the Scheffé test with IBM SPSS ver. 25.0, and importance–performance analysis (IPA) was conducted to prioritize educational needs.
Results:
Across all career groups, the “direct nursing performance” domain showed the highest task performance. Novice nurses with <3 years of experience reported significantly higher performance in central line care and transfusion management than those with ≥9 years of experience. The IPA identified central line management, and transfusion management as priority areas for improvement, while vital sign monitoring, respiratory surveillance and discharge education for parents were common educational needs regardless of experience level.
Conclusion
Educational programs for novice NICU nurses should focus on strengthening patient safety–related competencies and should be progressively structured with simulation and case-based learning to enhance clinical performance.

Subarachnoid hemorrhage (SAH) is a stroke subtype with high mortality and poor functional outcomes. Prompt occlusion of a ruptured aneurysm at an early stage is crucial to prevent rebleeding, which can result in even higher mortality and more severe disabilities. The most critical initial decision in SAH management is the choice of treatment method with surgical clipping or endovascular coiling. We aimed to develop an evidence-based clinical guideline to select the optimal initial treatment in patients with SAH. We developed this guideline based on evidence from systematic reviews and meta-analyses via a de novo process. A systematic literature review was conducted across four databases (MEDLINE, Embase, Cochrane, and KoreaMed) to answer two population, intervention, comparison, outcome questions comparing clipping and coiling. The risk of bias was assessed using ROB 2.0 and the Newcastle-Ottawa Scale. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses flow diagrams and meta-analyses were generated for functional outcome and mortality. We included six randomized control trials (RCTs) and 58 observational studies. Meta-analysis of RCTs showed that coiling improved functional outcomes compared to clipping (odds ratio [OR], 0.91; 95% confidence interval [CI], 0.86–0.97). No significant mortality difference was observed in RCTs (OR, 1.38; 95% CI, 0.91–2.09), but non-RCTs favored clipping for reduced mortality (OR, 0.77; 95% CI, 0.69–0.86). However, it is difficult to generalize these findings to all clinical situations, as patients with SAH have a highly variable clinical course. Final treatment decision should be tailored to the individual patient’s status, including aneurysm location, morphology, and the expertise available at the treatment center. Such decisions are best made by specialists such as a board-certified physician and should be explained to the patient and their caregivers, along with the rationale for selecting the most appropriate treatment at the given hospital. Korea has many certified endovascular neurosurgeons, cerebrovascular surgeons, and certified cerebrovascular centers. Proper selection of the most suitable treatment method by certified physicians and centers would greatly benefit patient outcomes and healthcare professionals.

Accurate and early identification of stroke and large vessel occlusion (LVO) in emergency settings is essential for improving patient outcomes and ensuring the efficient allocation of medical resources. This clinical practice guideline systematically reviews domestic and international literature and conducts meta-analyses to evaluate the utility and diagnostic accuracy of stroke assessment tools used in prehospital emergency medical services (EMS). We developed a guideline based on evidence from systematic reviews and meta-analyses via a de novo process. A systematic literature review was conducted to evaluate the usefulness of diagnostic EMS assessment tools for diagnosing stroke and LVO. Overall, 70 non-randomized control studies were selected for this study. A meta-analysis was conducted with a subgroup analysis to distinguish between patients with stroke and those with LVO. EMS tools demonstrated high sensitivity but low specificity for diagnosing stroke. In the prehospital setting, using validated EMS stroke assessment tools is recommended for the early identification of stroke and LVO. Upon hospital arrival, stroke specialists should conduct further evaluation and triage to confirm the diagnosis and guide appropriate management. Delays in diagnosing LVO are frequently unacceptable. While experts advocate for the use of EMS assessment tools to facilitate early identification of LVO, these tools alone lack adequate sensitivity. Therefore, further diagnostic evaluations and consultation with stroke specialists upon hospital arrival are recommended.

The mothership (MS) model, where patients are directly transferred to a thrombectomy-capable center, and the drip-and-ship (DS) model, where thrombolysis is initiated at the nearest primary stroke center before transfer for thrombectomy, are the primary transport modes for patients with stroke. We aimed to establish guidelines for selecting the appropriate transfer strategy based on emergent large vessel occlusion (LVO). We developed this guideline based on evidence from systematic reviews and meta-analyses via a de novo process. A systematic literature review was conducted across four databases (MEDLINE, Embase, Cochrane, and KoreaMed) to answer three Population, Intervention, Comparison, and Outcome questions comparing MS and DS models. The risk of bias was assessed using the Newcastle-Ottawa Scale. Preferred Reporting Items for Systematic Reviews and Meta-Analyses flow diagrams and meta-analyses were generated for functional outcomes, mortality, and successful recanalization. Twenty-six non-randomized controlled studies showed that the MS model improved good functional outcomes by approximately 14% compared with the DS model (odds ratio [OR], 1.14; 95% confidence interval [CI], 1.00–1.30). Fifteen studies reported that mortality in the MS and DS models showed no significant differences (OR, 0.97; 95% CI, 0.84–1.11). Twenty-four studies revealed no significant difference in successful recanalization between the MS and DS models (OR, 0.87; 95% CI, 0.68–1.10). The MS model should be considered first to improve the functional outcome of patients with LVO. However, if thrombectomy cannot be performed immediately after thrombolysis, or if a thrombectomy-enabled hospital is not nearby, the DS model should be considered by stroke specialists depending on transportation time and regional factors. We suggest a mixed approach with the DS model based on specific circumstances or regions to ensure the optimum treatment of patients with acute ischemic stroke (AIS). Appropriate transport for patients with LVO improves the prognosis of AIS.

Korean Journal of Radiology 2025;26(1):75-87
Objective:
To assess the feasibility of ultrafast brain magnetic resonance imaging (MRI) in pediatric patients.
Materials and Methods:
We retrospectively reviewed 194 pediatric patients aged 0 to 19 years (median 10.2 years) who underwent both ultrafast and conventional brain MRI between May 2019 and August 2020. Ultrafast MRI sequences included T1 and T2-weighted images (T1WI and T2WI), fluid-attenuated inversion recovery (FLAIR), T2*-weighted image (T2*WI), and diffusion-weighted image (DWI). Qualitative image quality and lesion evaluations were conducted on 5-point Likert scales by two blinded radiologists, with quantitative assessment of lesion count and size on T1WI, T2WI, and FLAIR sequences for each protocol. Wilcoxon signed-rank tests and intraclass correlation coefficient (ICC) analyses were used for comparison.
Results:
The total scan times for equivalent image contrasts were 1 minute 44 seconds for ultrafast MRI and 15 minutes 30 seconds for conventional MRI. Overall, image quality was lower in ultrafast MRI than in conventional MRI, with mean quality scores ranging from 2.0 to 4.8 for ultrafast MRI and 4.8 to 5.0 for conventional MRI across sequences (P < 0.001 for T1WI, T2WI, FLAIR, and T2*WI for both readers; P = 0.018 [reader 1] and 0.031 [reader 2] for DWI). Lesion detection rates on ultrafast MRI relative to conventional MRI were as follows: T1WI, 97.1%; T2WI, 99.6%; FLAIR, 92.9%; T2*WI, 74.1%; and DWI, 100%. The ICC (95% confidence interval) for lesion size measurements between ultrafast and conventional MRI was as follows: T1WI, 0.998 (0.996–0.999); T2WI, 0.998 (0.997–0.999); and FLAIR, 0.99 (0.985–0.994).
Conclusion
Ultrafast MRI significantly reduces scan time and provides acceptable results, albeit with slightly lower image quality than conventional MRI, for evaluating intracranial abnormalities in pediatric patients.

8.Effects of Death Attitude, Self-esteem, and Perceived Risk of Respiratory Infectious Diseases on Death Anxiety among Nurses in COVID-19 Wards
Journal of Korean Academy of Psychiatric and Mental Health Nursing 2025;34(1):5-15
Purpose:
To provide foundational data for developing death anxiety intervention programs for nurses by identifying the factors influencing their death anxiety in COVID-19 wards.
Methods:
This descriptive survey study involved 123 nurses who had worked for more than six months in the COVID-19 wards of a tertiary hospital in Metropolitan B City. Data were collected using a structured self-report questionnaire from March 22 to April 9, 2022.
Results:
Death anxiety differed significantly by gender (t=-3.32, p=.001). It showed a significant positive correlation with the perceived risk of respiratory infectious disease (r=.29, p=.001) but significant negative correlations with death attitude (r=-.69, p<.001) and self-esteem (r=-.18, p=.049). Factors influencing death anxiety included death attitude (β=-.67, p<.001) and gender (β=.23, p<.001), accounting for 52.4% of the variance.
Conclusion
This study found that death attitude and gender significantly influenced death anxiety among nurses in COVID-19 wards. Therefore, it is neccessary to develop and apply gender-sensitive death anxiety intervention programs that could positively and effectively influence death attitudes to reduce death anxiety of nurses in covid-19 wards.
