Korea Nurses' Health Study and the health of reproductive-aged women: a cohort profile.

The Korea Nurses' Health Study (KNHS) is an ongoing, large-scale, prospective cohort study of female nurses, focusing on the effects of occupational, environmental, and lifestyle factors on the health of women. The first KNHS survey was performed in 2013-2014 (n=20,613). As of December 2023, 11 follow-up surveys have been conducted. Participants who were pregnant were asked to participate in the early pregnancy survey (n=2,179) and postpartum survey after giving birth (n=2,790). The main variables included sociodemographic, work-related, lifestyle, physical, mental, and women's health factors. Blood, urine, and toenail samples were collected from a participant subgroup of the first survey (n=1,983). The subgroups of the second survey completed a food frequency questionnaire in 2019 (n=300) and 2021 (n=871). In 2020, a subgroup of the first survey answered a coronavirus disease 2019 (COVID-19)-related survey (n=975). To examine various health-related factors in young adults, new participants were added to the KNHS cohort in the 11th (n=1,000) and 12th (n=1,002) surveys. The KNHS cohort will help identify health and illness determinants in Korean women. Data can be accessed at https://coda.nih.go.kr/frt/index.do.

The effects of mobile technology-based support on young women with depressive symptoms: A block randomized controlled trial.

BACKGROUND: The current body of knowledge highlights the potential role of mobile technology as a medium to deliver support for psychological and physical health. This study evaluated the influence of mobile technology support on depressive symptoms and physical activity in female university students. METHODS: A block randomized controlled trial design with a single site was used. Ninety-nine participants were block-randomized into 3 arms: Experimental Group 1 (emotional and informational support group), Experimental Group 2 (informational support group), and the control group. Interventions were delivered via mobile technology for 2 weeks. Data on depressive symptoms and physical activity were collected from 84 participants at baseline and on Days 8 and 15. Data analyses included descriptive statistics, t tests, one-way analysis of variance, and repeated-measures analysis of variance. RESULTS: This study showed no interaction effect of time and group on depressive symptom scores and physical activity, considering the emotional and informational support from mobile technology. However, Experimental Group 1 exhibited a significant reduction in depressive symptoms during the first week of the study compared to Experimental Group 2 and the control group. While physical activity in Experimental Group 2 and control group increased only during the first week of the study and subsequently decreased, Experimental Group 1 showed an initial increase during the first week that was sustained into the second week. CONCLUSIONS: Since informational and emotional support showed a strong effect over a short period of time, mobile technology offering emotional support could be used to provide crisis interventions for depression among young women when a short-term impact is required.

The Potential of Chatbots for Emotional Support and Promoting Mental Well-Being in Different Cultures: Mixed Methods Study.

BACKGROUND: Artificial intelligence chatbot research has focused on technical advances in natural language processing and validating the effectiveness of human-machine conversations in specific settings. However, real-world chat data remain proprietary and unexplored despite their growing popularity, and new analyses of chatbot uses and their effects on mitigating negative moods are urgently needed. OBJECTIVE: In this study, we investigated whether and how artificial intelligence chatbots facilitate the expression of user emotions, specifically sadness and depression. We also examined cultural differences in the expression of depressive moods among users in Western and Eastern countries. METHODS: This study used SimSimi, a global open-domain social chatbot, to analyze 152,783 conversation utterances containing the terms "depress" and "sad" in 3 Western countries (Canada, the United Kingdom, and the United States) and 5 Eastern countries (Indonesia, India, Malaysia, the Philippines, and Thailand). Study 1 reports new findings on the cultural differences in how people talk about depression and sadness to chatbots based on Linguistic Inquiry and Word Count and n-gram analyses. In study 2, we classified chat conversations into predefined topics using semisupervised classification techniques to better understand the types of depressive moods prevalent in chats. We then identified the distinguishing features of chat-based depressive discourse data and the disparity between Eastern and Western users. RESULTS: Our data revealed intriguing cultural differences. Chatbot users in Eastern countries indicated stronger emotions about depression than users in Western countries (positive: P<.001; negative: P=.01); for example, Eastern users used more words associated with sadness (P=.01). However, Western users were more likely to share vulnerable topics such as mental health (P<.001), and this group also had a greater tendency to discuss sensitive topics such as swear words (P<.001) and death (P<.001). In addition, when talking to chatbots, people expressed their depressive moods differently than on other platforms. Users were more open to expressing emotional vulnerability related to depressive or sad moods to chatbots (74,045/148,590, 49.83%) than on social media (149/1978, 7.53%). Chatbot conversations tended not to broach topics that require social support from others, such as seeking advice on daily life difficulties, unlike on social media. However, chatbot users acted in anticipation of conversational agents that exhibit active listening skills and foster a safe space where they can openly share emotional states such as sadness or depression. CONCLUSIONS: The findings highlight the potential of chatbot-assisted mental health support, emphasizing the importance of continued technical and policy-wise efforts to improve chatbot interactions for those in need of emotional assistance. Our data indicate the possibility of chatbots providing helpful information about depressive moods, especially for users who have difficulty communicating emotions to other humans.

Factors influencing the burnout dimensions among nurses: A cross-sectional study in South Korea.

AIM: To investigate the factors influencing three dimensions of burnout among clinical nurses in South Korea. DESIGN: Descriptive, correlational and cross-sectional study. METHODS: We recruited 300 clinical nurses to participate in an online survey conducted in June 2021. Purposive sampling was used for the survey. Multiple linear regression was used for data analysis. RESULTS: The regression models explained 55.8%, 45.8% and 34.3% variances in emotional exhaustion, depersonalization and personal accomplishment respectively. Emotional exhaustion was influenced by experience in the current department, working overtime, shift type, depression, job stress and emotional labour. Depersonalization was influenced by gender, hospital size, the associated department, overtime, coping strategies, depression and emotional labour. Personal accomplishment was influenced by clinical experience, shift type, resilience and the perceived threat of coronavirus disease 2019.

Interventions to reduce burnout among clinical nurses: systematic review and meta-analysis.

Sporadic evidence exists for burnout interventions in terms of types, dosage, duration, and assessment of burnout among clinical nurses. This study aimed to evaluate burnout interventions for clinical nurses. Seven English databases and two Korean databases were searched to retrieve intervention studies on burnout and its dimensions between 2011 and 2020.check Thirty articles were included in the systematic review, 24 of them for meta-analysis. Face-to-face mindfulness group intervention was the most common intervention approach. When burnout was measured as a single concept, interventions were found to alleviate burnout when measured by the ProQoL (n = 8, standardized mean difference [SMD] = - 0.654, confidence interval [CI] = - 1.584, 0.277, p < 0.01, I2 = 94.8%) and the MBI (n = 5, SMD = - 0.707, CI = - 1.829, 0.414, p < 0.01, I2 = 87.5%). The meta-analysis of 11 articles that viewed burnout as three dimensions revealed that interventions could reduce emotional exhaustion (SMD = - 0.752, CI = - 1.044, - 0.460, p < 0.01, I2 = 68.3%) and depersonalization (SMD = - 0.822, CI = - 1.088, - 0.557, p < 0.01, I2 = 60.0%) but could not improve low personal accomplishment. Clinical nurses' burnout can be alleviated through interventions. Evidence supported reducing emotional exhaustion and depersonalization but did not support low personal accomplishment.

Risk of uterine leiomyomata with menstrual and reproductive factors in premenopausal women: Korea nurses' health study.

BACKGROUND: Uterine leiomyomata (UL) are benign smooth muscle tumors that may cause significant morbidity in women of reproductive age. This study aimed to investigate the relationship of menstrual and reproductive factors with the risk of UL in premenopausal women. METHODS: This prospective study included 7,360 premenopausal women aged 22-48 years who were part of the Korea Nurses' Health Study. Information on the menstrual cycle and reproductive history was assessed between 2014 and 2016, and self-reported cases of UL were obtained through 2021. Cox proportional hazards models were used to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs). RESULTS: During 32,072 person-years of follow-up, 447 incident cases of UL were reported. After adjusting for other risk factors, women with late age at menarche had a lower incidence of UL (≥ 16 vs. 12-13 years: HR 0.68; 95% CI 0.47-0.99; p for trend = 0.026). The risk of UL was inversely associated with current menstrual cycle length (≥ 40 or too irregular to estimate vs. 26-31 days: HR 0.40; 95% CI 0.24-0.66) and cycle length at ages 18-22 years (HR 0.45; 95% CI 0.31-0.67; p for trend < 0.001, each). Parous women had lower risk of UL than nulliparous women (HR 0.40; 95% CI 0.30-0.53) and women who were aged 29-30 years at first birth had a lower risk of UL than those who were aged ≤ 28 years at first birth (HR 0.58; 95% CI 0.34-0.98). There was no significant association of the number of births or breastfeeding with the risk of UL among parous women. Neither a history of infertility nor oral contraceptive use was associated with the risk of UL. CONCLUSIONS: Our results suggest that age at menarche, menstrual cycle length, parity, and age at first birth are inversely associated with the risk of UL in premenopausal Korean women. Future studies are warranted to confirm the long-term effects of menstrual and reproductive factors on women's health.

Comparison of factors associated with postpartum depression from two cohorts of nurses: the Korea Nurses' Health Study and the Nurses' Health Study 3.

OBJECTIVES: This study aimed to identify whether differences exist in postpartum depression (PPD) in US and Korean nurses and its related factors. Identifying occupational and personal factors that underlie potential differences will be helpful for women's occupational health. METHODS: Baseline and postpartum survey data from employed nurses in the Korea Nurses' Health Study and Nurses' Health Study 3 (1244 Korean; 2742 US nurses) were analysed. Postpartum data collection was done via online survey. PPD was analysed based on cultural validation from prior studies using the Edinburgh Postnatal Depression Scale (cut-off of 10 for Korea and 13 for USA); depressive symptoms prior to pregnancy and childbirth, general characteristics and sleep satisfaction were also measured. Descriptive statistics, χ2 tests and t-tests and multivariate ordinal logistic regression analysis were performed. RESULTS: 45.9% of Korean participants had clinical symptoms of PPD (≥10), whereas US participants presented with 3.4% (≥13). Prior depressive symptoms were also higher in Korean participants (22.5%) compared with their US counterparts (4.5%). Prior depressive symptoms and poor sleep satisfaction were significant risk factors of PPD in both cohort groups, and vaginal birth was an additional influencing factor in Korean participants. CONCLUSIONS: Differences in PPD rates and related factors suggest the role of stress, cultural variation and differing work systems. Nurses and other women shift-workers noted to have depressive symptoms before and during pregnancy and exhibit PPD symptoms should especially be followed closely and offered supportive mental health services that include greater flexibility in returning to work.

User-Chatbot Conversations During the COVID-19 Pandemic: Study Based on Topic Modeling and Sentiment Analysis.

BACKGROUND: Chatbots have become a promising tool to support public health initiatives. Despite their potential, little research has examined how individuals interacted with chatbots during the COVID-19 pandemic. Understanding user-chatbot interactions is crucial for developing services that can respond to people's needs during a global health emergency. OBJECTIVE: This study examined the COVID-19 pandemic-related topics online users discussed with a commercially available social chatbot and compared the sentiment expressed by users from 5 culturally different countries. METHODS: We analyzed 19,782 conversation utterances related to COVID-19 covering 5 countries (the United States, the United Kingdom, Canada, Malaysia, and the Philippines) between 2020 and 2021, from SimSimi, one of the world's largest open-domain social chatbots. We identified chat topics using natural language processing methods and analyzed their emotional sentiments. Additionally, we compared the topic and sentiment variations in the COVID-19-related chats across countries. RESULTS: Our analysis identified 18 emerging topics, which could be categorized into the following 5 overarching themes: "Questions on COVID-19 asked to the chatbot" (30.6%), "Preventive behaviors" (25.3%), "Outbreak of COVID-19" (16.4%), "Physical and psychological impact of COVID-19" (16.0%), and "People and life in the pandemic" (11.7%). Our data indicated that people considered chatbots as a source of information about the pandemic, for example, by asking health-related questions. Users turned to SimSimi for conversation and emotional messages when offline social interactions became limited during the lockdown period. Users were more likely to express negative sentiments when conversing about topics related to masks, lockdowns, case counts, and their worries about the pandemic. In contrast, small talk with the chatbot was largely accompanied by positive sentiment. We also found cultural differences, with negative words being used more often by users in the United States than by those in Asia when talking about COVID-19. CONCLUSIONS: Based on the analysis of user-chatbot interactions on a live platform, this work provides insights into people's informational and emotional needs during a global health crisis. Users sought health-related information and shared emotional messages with the chatbot, indicating the potential use of chatbots to provide accurate health information and emotional support. Future research can look into different support strategies that align with the direction of public health policy.

High-Risk Symptom Cluster Groups for Work-Life Quality and Turnover Intention among Nurses.

This cross-sectional study aims to identify high-risk symptom cluster groups for assessing the quality of nursing work life (QNWL) and turnover intention among Korean nurses who have experienced workplace violence. Nurses were recruited for an online survey in May 2021 (n = 203). The following four symptom clusters are extracted: (a) depression-anxiety, (b) shame-somatization, (c) nightmare-loss of appetite, and (d) anger-shock. Three symptom cluster groups were identified. Group 1 had the highest score for the anger-shock symptom cluster, as well as the highest symptom scores and turnover intention. Group 2 had the highest score for the nightmare-loss of appetite symptom cluster and the lowest QNWL. Group 3 had a similar symptom cluster pattern to Group 1 but lower scores for all symptom clusters. Symptom monitoring and programs tailored to symptom cluster groups at the institutional level could be useful for managing QNWL and turnover intention.

Depressive symptoms and menstrual distress according to the menstrual phase in nurses: the Korea Nurses' Health Study.

OBJECTIVE: This study aimed to identify the level of menstrual distress among nurses during the premenstrual and menstrual phases and to investigate associations between depressive symptoms and menstrual distress. METHODS: This was a cross-sectional study conducted using data from the Korea Nurses' Health Study. We used data from December 2018 to September 2019. A total of 6878 nurses was selected for final analysis. Data on demographic characteristics, women's health-related variables, shift work, sleep quality, depressive symptoms and menstrual distress were collected. Descriptive statistics, and hierarchical multiple regression analysis were used. RESULTS: Depressive symptoms were significantly correlated with menstrual distress in both premenstrual and menstrual phases (premenstrual phase B = 1.60, 95% CI = 1.49-1.71; menstrual phase B = 1.65, 95% CI = 1.54-1.76) after controlling for demographic characteristics, women's health-related variables, shift work and sleep quality. CONCLUSION: The results of this study indicate the importance of tailored care for menstrual distress based on the menstrual phase and the significance of depressive symptoms in the management of menstrual distress.

Nursing simulation practicum for delivery care: A scoping review.

OBJECTIVES: The purpose of this scoping review was to explore the state of the current body of knowledge on the use of nursing simulation for maternal nursing practicum with a focus on content and measured outcomes. DESIGN: This is a scoping review. DATA SOURCES: The literature search was performed using five databases (CINAHL, Cochrane, EMBASE, PubMed, and Web of Science). REVIEW METHOD: The review was conducted on quantitative and reflection/review studies that evaluated or described nursing simulation for delivery care, published between 2000 and 2020 in English and Korean. Two authors independently reviewed the studies and their references for additional literature search. Selected studies were charted to describe the study characteristics, and content and outcome of nursing simulation for delivery care. RESULTS: Fifteen articles were included in the review, of which twelve were intervention studies and three were reflection/review studies. The duration of the nursing simulations for delivery care ranged from 20 min to 4 h, with two to eight students in each simulation group. All nursing simulations focused on the normal, uncomplicated delivery process, with nine studies engaging in debriefing, but without pre- and/or post-assessments. The most frequently measured outcomes were knowledge, satisfaction, and clinical practice competency. CONCLUSIONS: Studies investigating nursing simulation pedagogy for delivery care were scarce, with limitations in the study designs and large variations in nursing simulation time across studies. Scenarios for nursing simulation for delivery care were rudimentary, and they usually focused on normal uncomplicated deliveries. The development of scenarios for high-risk deliveries and integration of pre-and/or post-assessments and debriefing into the nursing simulation are recommended to improve learning outcomes.

Misinformation, believability, and vaccine acceptance over 40 countries: Takeaways from the initial phase of the COVID-19 infodemic.

The COVID-19 pandemic has been damaging to the lives of people all around the world. Accompanied by the pandemic is an infodemic, an abundant and uncontrolled spread of potentially harmful misinformation. The infodemic may severely change the pandemic's course by interfering with public health interventions such as wearing masks, social distancing, and vaccination. In particular, the impact of the infodemic on vaccination is critical because it holds the key to reverting to pre-pandemic normalcy. This paper presents findings from a global survey on the extent of worldwide exposure to the COVID-19 infodemic, assesses different populations' susceptibility to false claims, and analyzes its association with vaccine acceptance. Based on responses gathered from over 18,400 individuals from 40 countries, we find a strong association between perceived believability of COVID-19 misinformation and vaccination hesitancy. Our study shows that only half of the online users exposed to rumors might have seen corresponding fact-checked information. Moreover, depending on the country, between 6% and 37% of individuals considered these rumors believable. A key finding of this research is that poorer regions were more susceptible to encountering and believing COVID-19 misinformation; countries with lower gross domestic product (GDP) per capita showed a substantially higher prevalence of misinformation. We discuss implications of our findings to public campaigns that proactively spread accurate information to countries that are more susceptible to the infodemic. We also defend that fact-checking platforms should prioritize claims that not only have wide exposure but are also perceived to be believable. Our findings give insights into how to successfully handle risk communication during the initial phase of a future pandemic.

Sexual Violence as a Key Predictor of Depressive Symptoms in Women: Korean Longitudinal Survey of Women and Families.

The purpose of this study was to identify the influence of violence on depressive symptoms in women. We analyzed panel data from the Korean Longitudinal Survey of Women and Families (n = 6,632). Exposure to sexual violence was a significant predictor of the onset of depressive symptoms. After adjusting for all covariates, other predictors included the perception of a poor or very poor health status than normal and participants in their 40s and 50s versus participants younger than 40 years. Assessing exposure to sexual violence might be beneficial for evaluating depressive symptoms in women who are newly diagnosed with depression.

Healing from sexual violence among young women in South Korea.

Reports of sexual violence against young women have been increasing. Due to limited support, young women who experience sexual violence have difficulties in healing, resulting in long-term consequences for individuals and society. We used grounded theory combined with a Photovoice approach to explore young women's experience of healing from sexual violence. From interviews and Photovoice activities of 29 participants, we identified a social process of healing that included internalizing anger, cutting off connections, reaching a turning point with support, restoring connections, struggling through individual internal processes, and transforming sexual violence into a stepping stone. The process of healing from sexual violence identified in this study shows commonalities as well as cultural and age-specific aspects from experiences of sexual violence among young women. In addition, this theory presented a new perspective on healing that contrasts with the past belief that disclosure is the key to healing.

Symptoms and management of long COVID: A scoping review.

AIM: This scoping review aims to describe published work on the symptoms and management of long COVID conditions. BACKGROUND: Symptoms and management of COVID-19 have focused on the acute stage. However, long-term consequences have also been observed. METHODS: A scoping review was performed based on the framework suggested by Arksey and O'Malley. We conducted a literature search to retrieve articles published from May 2020 to March 2021 in CINHAL, Cochrane library, Embase, PubMed and Web of science, including backward and forward citation tracking from the included articles. Among the 1880 articles retrieved, 34 articles met our criteria for review: 21 were related to symptom presentation and 13 to the management of long COVID. RESULTS: Long COVID symptoms were described in 21 articles. Following COVID-19 treatment, hospitalised patients most frequently reported dyspnoea, followed by anosmia/ageusia, fatigue and cough, while non-hospitalised patients commonly reported cough, followed by fever and myalgia/arthralgia. Thirteen studies described management for long COVID: Focused on a multidisciplinary approach in seven articles, pulmonary rehabilitation in three articles, fatigue management in two articles and psychological therapy in one study. CONCLUSION: People experience varied COVID-19 symptoms after treatment. However, guidelines on evidence-based, multidisciplinary management for long COVID conditions are limited in the literature. The COVID-19 pandemic may extend due to virus mutations; therefore, it is crucial to develop and disseminate evidence-based, multidisciplinary management guidelines. RELEVANCE TO CLINICAL PRACTICE: A rehabilitation care plan and community healthcare plans are necessary for COVID-19 patients before discharge. Remote programmes could facilitate the monitoring and screening of people with long COVID.

Influence of Irritable Bowel Syndrome on Stress and Depressive Symptoms in Nurses: The Korea Nurses' Health Study.

Despite the high risk of irritable bowel syndrome (IBS) and stress/depressive symptoms in nurses, limited research has examined the relationship between these conditions in female nurses. The purpose of this study was to determine the prevalence of IBS and the influence of IBS on stress and depressive symptoms in female nurses. We analyzed the data from the Korea Nurses' Health Study. Among 7667 participants from the 7th survey conducted from December 2018 to September 2019, 178 nurses were identified as having IBS based on the Rome IV criteria. Using the propensity score matching, 712 were selected as a comparison group. Multivariate ordinal logistic regression analyses were conducted to examine the influence of IBS on stress and depressive symptoms. The prevalence of IBS was 2.3% and the prevalence of depressive symptoms among nurses with IBS was 13.5%. Female nurses with IBS were 2.214 times more likely to experience increased stress levels. However, when demographics, dietary habits, sleep quality, and depressive symptoms were considered, having IBS was no longer an influential factor for increased stress levels. When all the variables were considered, female nurses with IBS were still 2.205 times more likely to experience depressive symptoms. Adequate support is needed to relieve depressive symptoms in nurses with IBS.

Information flow and nursing care during the early phase of the COVID-19 pandemic.

AIMS: This study aimed to understand the dissemination of information relating to coronavirus disease 2019 (COVID-19) and its impact on nursing care in the early phase of transmission. BACKGROUND: COVID-19 has spread globally, causing an unprecedentedly large number of casualties. Nurses face challenges in dealing with patients with COVID-19 with limited information about the pathogen. DESIGN: This qualitative study followed the COREQ guidelines. METHODS: Fifteen nurses were recruited from two university hospitals in South Korea using a snowballing technique for in-depth interviews in May 2020. All interviews were recorded and transcribed verbatim. Content analysis was performed on the interview data. RESULTS: Two themes emerged: access to COVID-19 information and the impact of information on nursing care. The categories of access to COVID-19 information were lack of nursing-specific information, limited information cascading from top management and confusion due to varying points of view. The categories of the impact of information on nursing care were unprepared management that aggravates exhaustion, lack of personal protective equipment that creates anxiety and being a nurse leader to overcome the pandemic. CONCLUSION: During a pandemic of emerging infectious diseases, nurses should have access to up-to-date information tailored to their working environment. Human resources, material resources and systematic support are needed for nurses who provide care for patients with an infectious disease. RELEVANCE TO CLINICAL PRACTICE: A collaborative interprofessional education system for emerging infectious diseases is needed for effective communication and consistent care during a pandemic. Nurse leaders should be prepared to deliver profession-specific information for standardised care and respond to nursing management needs by using resources and tailoring the workforce.

Nurse turnover: A longitudinal survival analysis of the Korea Nurses' Health Study.

AIMS: To identify factors influencing turnover among Korean female nurses from a longitudinal perspective. DESIGN: A national cohort study called the Korea Nurses' Health Study (2013-2020) was used. METHODS: A national sample of female nurses from module 1 (N = 20,613, 2013-2014), module 5 (N = 11,527, 2016-2017), module 7 (N = 8,658, 2018-2019) and module 8 (N = 10,253, 2019-2020) was used. Based on a nurse turnover model, individual, health-related, social work environment and work organizational factors were considered explainable variables for nurse turnover. Kaplan-Meier survival analysis and multivariate Cox regression analysis were used to identify the factors influencing female nurse turnover in South Korea. RESULTS: Female nurses who had less education, were unmarried, were pregnant, and had higher stress levels and an increased probability of experiencing turnover as they aged. Those who perceived moderate health rather than good/very good health, had depressive symptoms, had a higher salary, were charge nurses/unit managers/supervisors or advanced practice nurses, were advanced practice nurses rather than registered nurses, worked shifts, worked in special care units or outpatient wards/administration as opposed to general wards, and worked in larger hospitals had a decreased probability of experiencing turnover as they aged. A two-way interaction analysis revealed that those who had depressive symptoms and increased perceived stress were more likely to experience turnover as they aged. CONCLUSION: Multiple factors influenced female nurse turnover, including individual, health-related, social work environment and work organizational factors. A multidimensional approach is needed to reduce nurse turnover. IMPACT: Various factors predict nurse turnover as nurses age, implying that a multifaceted approach is needed to manage nurse turnover. The influence of depressive symptoms on turnover should be evaluated by considering the perceived stress level. Nursing managers and policy makers could use our results to develop programs/policies to reduce nurse turnover.

Predictors of actual turnover among nurses working in Korean hospitals: A nationwide longitudinal survey study.

AIM: To examine the factors affecting actual turnover among nurses working in hospitals using the Brewer-Kovner synthesis model. BACKGROUND: To increase retention of nurses, it is important to understand factors contributing to actual turnover among nurses. METHODS: A longitudinal study design was utilized with 2,633 of 20,613 eligible female hospital nurses who participated in Korea Nurses' Health Study. We created two age groups: a younger group (20-35 years) and an older group (36-49 years). Multivariate logistic regression was used to identify the factors influencing turnover by age group. RESULTS: Pregnancy and childbirth increased young nurses' turnover. When we excluded intent to leave, depression and burnout were significant factors affecting young nurses' turnover. Salary and hospital size were factors predicting nurse turnover among nurses older than 36 years. CONCLUSIONS: It is essential to develop prevention strategies of female nurse turnover based on the age group in Korea. IMPLICATIONS FOR NURSING MANAGEMENT: Nurse managers and health care institutes need to develop new managerial and policy strategies to reduce nurse turnover in each age group.
