Nurses’ experiences of children’s fall accidents in South Korea: a phenomenological study Hye Jin Kim, Hyun Young Koo Child Health Nursing Research, 2026 Purpose: This study aimed to explore nurses’ experiences with hospitalized children’s fall accidents. The findings are intended to provide foundational data for developing strategies to strengthen patient safety for children.Methods: Participants were purposively sampled. The sample consisted of eight nurses working in the pediatric departments of hospitals located in Daegu and Seoul in South Korea. All participants had experienced at least one fall accident involving a hospitalized child within the past year. Data were collected through in-depth interviews conducted between February 1 and April 30, 2025. The collected data were analyzed using Colaizzi’s phenomenological analysis method.Results: The data analysis revealed four themes and 12 subthemes, which were derived from 111 significant statements and reflect pediatric ward nurses’ experiences with inpatient fall incidents. The four themes were: “encountering fall risks beyond nurses’ control,” “ineffective fall education and formalized safety practices,” “limitations of assessment tools and the growth of reflective practice,” and “moving toward comprehensive fall prevention and management strategies.”Conclusion: Nurses recognized that the risk of pediatric falls was often beyond their control, and that fall prevention education did not always translate into practice. Reflective analysis of fall incidents, age- and patient-specific fall nursing interventions, and the establishment of an integrated support system are needed for effective fall prevention and management. These findings are expected to provide basic data to guide nursing care that prevents fall accidents and improves children’s patient safety.
Development of an educational intervention program for infant safe sleep practices in Korea: a methodological study Jung Ae Cho, Young Mee Ahn, Min Sohn, Ok Kyung Ham, Min Kyung Lim, et al. Child Health Nursing Research, 2026 Purpose: Education on infant safe sleep practices has been known to reduce the risk of sleep-related sudden unexpected infant death. Since sleep environments may vary across sociocultural contexts, infant safe sleep education needs to reflect specific sociocultural settings. This study aimed to develop an educational Protocol for Infant Safe Sleep (PISS) for primary caregivers in Korea that considers parenting behaviors and cultural characteristics.Methods: This study was conducted in three key methodological steps: (1) retrieval, defining, and systematic classification of PISS content; (2) the structural formulation of the content as an educational protocol; and (3) content validation. For the first step, a literature review was conducted, along with an analysis of educational materials from institution websites related to infant safe sleep and online parenting communities. Field observations were also conducted to identify relevant Korean culture characteristics. Based on these findings, the PISS was developed. Content validity index was assessed by six professionals, and the results were reflected into the educational program.Results: The PISS intervention provided an educational video and booklet and enhanced learning via phone counseling and educational kit, which comprised an illustrated safe sleep sticker and a calendar-style activity diary. The educational content consisted of (1) sleep location, (2) sleep position, (3) bedding, (4) clothes and temperature, and (5) other considerations.Conclusion: This study developed the PISS, an intangible educational intervention based on Korean sociocultural characteristics and specific guidelines for primary caregivers. Future research should evaluate the effectiveness of this program in promoting safe sleep practices.
Effects of a virtual reality program and simulation training for nursing students on the measurement of vital signs in children: a mixed-methods study in South Korea Sun Nam Park, Hyun Young Koo, Hye Young Hwang Child Health Nursing Research, 2025 Purpose: This study aimed to evaluate the effects of a virtual reality (VR) program and simulation training on nursing students’ ability to measure vital signs in children.Methods: This mixed-methods study, which included a randomized controlled trial and a qualitative study, was conducted from June 12 to November 15, 2023. Forty-four nursing students from a university in South Korea were randomly assigned to either the experimental or control group. The experimental group first participated in a VR program focused on measuring vital signs in children, followed by a high-fidelity simulation training. The control group received the training in the reverse order. The participants’ knowledge, confidence in practice, and satisfaction with the practice were analyzed using the repeated-measures analysis of variance. VR learning experiences were analyzed through qualitative content analysis.Results: Both the experimental and control groups showed significant increases in knowledge and confidence in practice after the interventions compared to baseline. However, there were no significant differences in changes in knowledge, confidence in practice, and satisfaction with practice between the two groups. Three themes were identified from the nursing students’ experiences with VR learning: ‘realistic learning training,’ ‘overcoming learning limitations,’ and ‘perceiving drawbacks.’Conclusion: The VR program was as effective as high-fidelity simulation training in improving nursing students’ ability to measure children’s vital signs. Moreover, VR program offered additional benefits in addressing limitations of simulation-based learning. These findings suggest that VR program can serve as a valuable educational tool to enhance pediatric nursing skills.
Tutoring experiences of a high-risk newborn care simulation among nurse tutors and nursing student tutees in South Korea: a qualitative study Hyun Young Koo, Bo Ryeong Lee, Hyeran An Child Health Nursing Research, 2025 Purpose: This study aimed to explore tutoring experiences related to a high-risk newborn care simulation among nurses and nursing students to derive insights into developing effective neonatal nursing practice.Methods: A qualitative content-analysis study was conducted in March 2023. Data were collected through narrative surveys and focus group interviews with four neonatal intensive care unit nurses and 12 senior nursing students participating in a 1-day high-risk newborn care simulation program. A content analysis was performed on the collected data.Results: Three categories (“efforts to foster a sense of presence,” “efforts to promote positive awareness of the neonatal intensive care unit,” and “establishing one’s role as an educator”) and six subcategories were derived from the nurses’ responses. Three categories (“growth through a realistic virtual simulation,” “improved learning effects,” and “hope for continued development”) and six subcategories were derived from the nursing students’ responses.Conclusion: The nursing students experienced realistic practice with their nurse tutors in the high-risk newborn care simulation, which helped them form their professional identity as future nurses. After tutoring, the nurses’ perceptions of nursing students changed positively, which affected their teaching methods.
Effects of transition programmes to adulthood for adolescents and young adults with CHD: a systematic review with meta-analysis Bo Ryeong Lee, Hyun Young Koo, Sangmi Lee Cardiology in the Young, 2024 Background: The increased survival rate among individuals with CHD has sparked interest in their transition to adult healthcare. Although there is a general agreement on the importance of transition interventions, the empirical evidence supporting them is insufficient. Therefore, this study aimed to conduct a systematic review and meta-analysis of transition interventions for adult healthcare in adolescents and young adults. Methods and results: A literature search was conducted for studies comparing the quantitative effects of transition interventions with control groups, published up to March 15, 2023, in major databases (CENTRAL, Embase, PubMed, Web of Science, CINAHL, KISS, and KMbase), major clinical trial registries, academic journal sites related to the topic, and grey literature databases. Ten studies involving a total of 1,297 participants were identified. Transition interventions proved effective in enhancing disease-related knowledge (Hedge’s g = 0.89, 95% CI = 0.29−1.48) and self-management (Hedge’s g = 0.67, 95% CI = 0.38−0.95), as well as reducing loss to follow-up (OR = 0.41, 95% CI = 0.22−0.77). The certainty of evidence for the estimated values of each major outcome was low or very low. Conclusions: This study supports the implementation of transition interventions by demonstrating that they can improve patients’ disease knowledge and self-management, while also promoting treatment continuity. However, since the available data on transition interventions for adolescents and young adults with CHD remain limited, the widespread adoption of structured transition interventions in the future may alter the conclusions of this study.

The effect of peer tutoring on pediatric nursing education: a systematic review Hyun Young Koo, Hyeran An, Bo Ryeong Lee Child Health Nursing Research, 2024 Purpose: This study aimed to systematically review studies on the effect of peer tutoring on pediatric nursing education for nursing students and identify its contents and characteristics.Methods: A comprehensive search was conducted from November to December 2023 across databases including PubMed, Embase, CENTRAL, CINAHL, ProQuest, and others. We included both published and unpublished literature in English or Korean. Three reviewers independently screened and selected eligible studies that involved undergraduate nursing students participating in peer tutoring programs focused on pediatric nursing education. We analyzed quantitative outcomes related to learning effects and learner responses. The quality of the studies was assessed using the revised Cochrane risk-of-bias tool for randomized trials and the risk of bias assessment tool for non-randomized studies.Results: Five studies were reviewed, encompassing randomized controlled trials, a non-randomized controlled trial, a cohort study, and a before-after study. These interventions were conducted in school settings or pediatric clinical environments and featured different forms of peer teaching: horizontal, near-peer, and reciprocal. The tutor-to-tutee ratios ranged from 1:3 to 1:36.5. The educational content covered nursing care for major neonatal diseases, communication skills, medication administration, and resuscitation techniques. Significant improvements in cognitive knowledge and communication skills were observed among nursing students. However, there was noticeable variability in the design and reporting of the studies.Conclusion: Peer tutoring programs can effectively enhance pediatric nursing education by improving nursing students’ knowledge and skills. For future meta-analyses, more studies in this field reported according to reporting guidelines are needed.
Development and evaluation of case video-based debriefing on a simulation of high-risk neonatal care for nursing students in South Korea: a mixed-methods study Hyun Young Koo, Bo Ryeong Lee, Hyeran An BMC Nursing, 2023 Background The debriefing process after health care simulations should provide a psychologically safe learning environment for nursing students. Case video-based debriefing on a simulation of high-risk neonatal care can help nursing students feel psychologically safe and make learning more effective. In this study, we developed case video-based debriefing materials for a simulation of high-risk neonatal care for nursing students in South Korea and evaluated their effects. Methods This mixed-methods study, consisting of a survey and an in-depth interview, was conducted between August and December 2022. The participants were 27 nursing students for the development of the case video-based debriefing and 51 nursing students for the evaluation of its effects (25 in the experimental group and 26 in the control group) at a university in South Korea. A case video-based debriefing on a simulation of high-risk neonatal care was developed, and the experimental group took part in case video-based debriefing. The participants’ self-efficacy, critical thinking, state anxiety, and satisfaction with practice were examined. The experimental group’s learning experiences were explored. Quantitative data were analyzed using the chi-square test, the unpaired t-test, and repeated-measures analysis of variance. Qualitative content analysis was conducted. Results In the experimental group, critical thinking and satisfaction with practice increased to a greater extent than in the control group. However, the changes in self-efficacy and state anxiety were not significantly different between the experimental and control groups. Four categories were extracted from nursing students who participated in the case video-based debriefing: “learning facilitated by the simulation,” “expanded learning,” “safe learning environment,” and “efficient utilization of case videos.” Conclusions Case video-based debriefing on a simulation of high-risk neonatal care effectively enhanced nursing students’ critical thinking and satisfaction with practice, and it will be utilized to improve nursing students’ competency in high-risk neonatal care.
