Purpose: The aim of this study was to identify the factors affecting the post-traumatic stress disorder (PTSD) symptoms of intensive care unit (ICU) nurses. The variables include event experiences, cognitive flexibility, and co-worker support. Methods: A survey was conducted among 153 ICU nurses working in a general hospital or an advanced general hospital. The questionnaire was completed between October and December 2018, and 153 copies were used for the final analysis. Data were analyzed using multiple linear regression to determine the factors associated with PTSD symptoms among ICU nurses. Results: The level of PTSD symptoms of ICU nurses was 1.20 ± 0.82 out of 4. Full PTSD, signified by a total score of 25 or more, was reported by 45.1% of the study's 153 participants. The significant influencing factors of PTSD symptoms among ICU nurses were the “experience of traumatic events,” “trusted alliance,” which is a subarea of “coworker support,” and both “control” and “alternative,” which are subareas of “cognitive flexibility.” The explanatory power (49.8%) was statistically significant. Conclusions These results suggest that a program to enhance the cognitive flexibility and coworker support of ICU nurses needs to be developed to reduce the PTSD symptoms of ICU nurses.

While healthcare data sets include extensive information about patients, many researchers have limitations in analyzing them due to their intrinsic characteristics such as heterogeneity, longitudinal irregularity, and noise. In particular, since the majority of medical history information is recorded in text codes, the use of such information has been limited due to the high dimensionality of explanatory variables. To address this problem, recent studies applied word embedding techniques, originally developed for natural language processing, and derived positive results in terms of dimensional reduction and accuracy of the prediction model. This paper reviews the deep learning-based natural language processing techniques (word embedding) and summarizes research cases that have used those techniques in the health care field. Then we finally propose a research framework for applying deep learning-based natural language process in the analysis of domestic health insurance data.

Purpose: This study aims to provide essential data for measures to enhance the professionalism of nursing experts and improve understanding of the explanationnurse's identity by examining their working experience in depth. Methods: Data were collected from August 12 through October 07, 2021. Participants were 13 explanation nurses with more than five years of nursing experience. Verbatim transcripts were analyzed using Colaizzi's phenomenological analysis. Results: Three theme clusters emerged from the data analysis: “Confusion from work that does not affect the identity of an explanation nurse”, “Entirely fulfilling role as a nursing professional”, and “Crave for the organization's support system for independent job performance”. Conclusion Earlier in the department change, nurses had difficulty establishing their identity regarding the explanation duties they must perform. Still, they wanted to continue their explanation work after struggling to pioneer and carry out their duties with expertise . Therefore, hospitals must support explanation nurses with a structural system as they begin their role to adapt to their work and strengthen their professionalism so that these nurses may provide a higher level of explanation nursing and patient-centered care.

Purpose: To determine the clinical manifestations and maternal and perinatal outcomes in pregnant women with coronavirus disease 2019 (COVID-19). Methods: We conducted a retrospective observational study of pregnant women with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection who were admitted to National Health Insurance Service (NHIS) Ilsan Hospital between August 2020 and October 2021. The maternal and perinatal outcomes were investigated. Results: Among 184 pregnant women infected with SARS-CoV-2, 79 women delivered. Of the women who delivered, with 36 women giving birth during the quarantine period. At delivery, 45 women were positive for SARS-CoV-2 by polymerase chain reaction (PCR), whereas 34 women were negative. The most common clinical manifestations were cough (65.2%), fever (38.0%), and myalgia (33.2%). Regarding perinatal outcomes, none of the babies had an Apgar score <7 at 5 minutes, and none were intubated following the delivery. The preterm birth rate and small-for-gestational-age (SGA) rate were 15.2% and 16.5%, respectively. All babies who was delivered at NHIS Ilsan Hospital were negative for SARS-CoV-2 infection by PCR, which was evaluated using amniotic fluid, cord blood, neonatal nasopharyngeal and oropharyngeal swabs in the 1st and 2nd days following delivery, although 45 women were positive for SARS-CoV-2 infection by PCR at the time of delivery. Conclusion Most pregnant women with COVID-19 in South Korea were unlikely to manifest symptoms or present with a severe disease progression. The observed preterm birth rate and SGA rate were higher in women with COVID-19 than in those without COVID-19. However, there was no evidence of vertical transmission, and all babies were negative for SARS-CoV-2 infection during pregnancy.

Purpose: This study aimed to identify the job characteristics of the integrated nursing care wards. Methods: For 388 nurses working in the integrated nursing wards of 30 hospitals, the importance, performance frequency, and difficulty of nursing tasks were analyzed using 31 job categories (678 items). Nursing tasks were analyzed using ImportancePerformance Analysis by hospital type. Results: Tertiary hospitals and general hospitals were analyzed using Importance-Performance Analysis, and the categories of general nursing intervention, spiritual and end of life nursing, and nursing during examination differed by hospital type. Other tasks into the same categories. 'Keep up the Good Work' includes 12 tasks: nursing assessment, medication and blood transfusion, admission or discharge management, and cooperation and coordination. 'Concentrate Here' had three tasks: emergency care, education to nurses, self-development. 'Possible Overkill' included supportive contact, environmental management, and product management. 'Low Priority' has ten tasks, including administration and organization management, facility management. Conclusion Nurses had different perceptions of importance and difficulty according to the tasks.Nursing during the examination, general nursing intervention, spiritual nursing, and end-of-life nursing were placed in different domains according to hospital type. Therefore, it is necessary to establish the nursing tasks and plan to improve workforce management, reflecting these differences.

The coronavirus disease 2019 (COVID-19) has emerged as a threat to human health and public safety. People of all ages are susceptible to severe acute respiratory syndrome coronavirus 2 infection. However, the clinical manifestations of this infection differ by age. This study purposes to describe healthcare considerations for special populations, such as children, pregnant and lactating women, and older adults, who may have unique healthcare needs, in the pandemic situation. To realize the research purpose, we conducted a review of the practice guidelines of public documents and qualified studies that were published online/offline during a specific period. The review identified current knowledge on care for newborns, children in schools, pregnant women (from antenatal to postpartum care), and older adults suffering from high-risk conditions. Subsequently, we summarize vaccination guidance for special populations and, finally, discuss the issues currently affecting special populations. Therefore, this current knowledge on care for special populations helps nurses to provide accurate information on vaccinations aimed at preventing COVID-19 and protecting the masses from infection. Currently, the scarcity of information on COVID-19 variants necessitates further research on measures to reduce pandemic spread.

Objectives: This study aimed to examine the correlations between the regional characteristics of counties in Gangwon Province, Republic of Korea and the ratio of intracounty to extracounty sources of coronavirus disease 2019 (COVID-19) infection. Methods: The region of the infectious contact was analysed for each COVID-19 case reported in Gangwon Province between February 22, 2020 and February 7, 2022. The population, population density, area, the proportion of urban residents, the proportion of older adults (>65 years), financial independence, and the number of adjacent counties were assessed for each of the 18 counties in Gangwon Province. Correlation coefficients between regional characteristics and the ratio of intracounty to extracounty infections were calculated. Results: In total, 19,645 cases were included in this study. The population, population density, proportion of older adults, and proportion of urban residents were significantly correlated with the ratio of intracounty to extracounty infections. A stratified analysis with an age cut-point of 65 years showed that the proportion of older adults had a significant negative correlation with the ratio of intracounty to extracounty infections. In other words, the proportions of extracounty infections were higher in countries with higher proportions of older adults. Conclusion Regions with ageing populations should carefully observe trends in infectious disease outbreaks in other regions to prevent possible transmission.

There are few studies on the severity and prognosis of patients infected with the severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) omicron variant. From January 11, 2022 to January 25, 2022, 181 patients were infected with the SARS-CoV-2 omicron variant in a single hospital in Korea. The initial clinical characteristics were investigated through the COVID-19 basic investigation form. Outcomes were reviewed using medical records. The median age of the patients was 57 years (range 1–90), and 95 patients (52.5%) were male. None were re-infected with SARS-CoV-2, and 127 (70.2%) were fully vaccinated (boosted or within 6 months after second vaccination). Forty-two patients (23.2%) were asymptomatic. Among symptomatic patients, the frequency of symptoms was as follows: cough (37.0%), sore throat (33.7%), and fever (30.4%). In terms of disease severity, 168 (92.8%) patients did not require supplemental oxygen, 6 (3.3%) required low-flow oxygen, 5 (2.8%) required high-flow oxygen, and 2 (1.1%) died. Four of the five individuals who required high-flow oxygen and the two who died were not vaccinated. Most of the patients who contracted the SARS-CoV-2 omicron variant exhibited mild clinical features; however, severe clinical features including mortality were encountered among individuals who were not vaccinated.

Background: and Objective: With the advancement of cancer treatments and increased life expectancy, managing breakthrough cancer pain (BTcP) is essential to improve the quality of life for cancer patients. This study aimed to compare the major rapid onset opioids in Korea based on their characteristics and costs to determine the best option for each patient. Methods: Based on sales information from IQVIA-MIDAS, sublingual fentanyl tablet (SLF), fentanyl buccal tablet (FBT), and oral transmucosal fentanyl citrate (OTFC) were selected as the top three drugs for the treatment of BTcP in Korea, considering them the most comparable drugs. The cost and cost-pain relief ratio of the drugs for short-term (1 month) and long-term (1 year) treatment were compared and the ease of administration based on various factors, including pharmacokinetics, onset of action, and administration procedures were evaluated. Results: SLF was evaluated as the best overall in terms of rapid onset of action, ease of administration, and drug cost and also had the highest market share. SLF had the lowest cost pain relief ratio for both the initial and supplemental treatment for the 1-month pain intensity difference 15 (PID15) ratio. However, for the 1-month PID30 ratio, SLF was not superior to OTFC or FBT. The longer the breakthrough cancer pain duration, the more cost-effective the other rapid onset opioids. Conclusion The rapid onset opioids that fit the patient’s breakthrough cancer pain pattern have the best cost-effectiveness.

Purpose: This year 2020 marks the 50th anniversary of the founding of the Korean Society of Nursing Science (KSNS). This study wasaimed to explore development of caring and describe the 50 years of history of KSNS within the sociocultural context of Korea regardingacademic footsteps, meanings, and implications for the future. Methods: This study used a historical research methodology using a literaturereview and bibliometric analysis. Relevant literature was reviewed and the published abstracts in the Journal of Korean Academy ofNursing (JKAN) were analyzed using VOSviewer. Results: Birth control and family planning in the 1970s was the main research topic. In the1980s, the development of nursing concepts, theories, and philosophies was the mission of KSNS to extend the disciplinary boundary. In the1990s, the progress of KSNS to become one of the woman-dominant healthcare professionals was the mission in the given period. Expandingthe frontiers of KSNS to the extent of global standards was the undertaking of the nursing scholars in the 2000s. Lastly, in the 2010s,the quality and quantity improvement of KSNS and JKAN is expected to make our future even prosperous. The map visualization of the 50years of research accumulation showed the comparable opposition of quantitative vs. qualitative research methodologies, equation modeling,and instrument development. Conclusion These clusters of research demonstrates the efforts to make nursing evidence by Koreannursing scholars for the last five decades. The growth in the slope of KSNS and outcomes of JKAN are to carry on to an unimaginable extentin the future.
