PURPOSE: The purpose of this study was to identify the research trends and instruments for assessment of sleep quality in Korea. METHODS: 66 quantitative research reports published from 2000 to March 2009 in Korea were selected from 5 databases: RISS4U, KISS, KISTI, DBpia, and the National Assembly Library and were analyzed according to criteria such as publication years, type of journal, participants, study fields, research design, participants, key words and instruments for assessment. RESULTS: Research in sleep quality has been rapidly increasing in recent years. More than half of the research analyzed was conducted in nursing. The majority of research methods were survey and correlational research. Patients with chronic illness and the elderly were the major subjects in those researches. Most research was performed based on hospitals and communities. The types of variables tested for their relation and influence on sleep quality were quite limited. With respect to the instrument used for assessing sleep quality, most studies did not consider whether or not the validity of their instrument had been established. CONCLUSION: It is recommended to conduct clinically applicable interventional research with an experimental design and to develop a reliability and validity established sleep quality instrument for Koreans.

PURPOSE: The purpose of this study was to analyze the research on adherence for secondary prevention in patients with coronary artery disease (CAD) in Korea, and to identify the strategies for improvement that should be included in future studies. METHODS: Electric literature searches were conducted for Pubmed, CINAHL, RISS4U, KISTI, DBpia, KoreaMed, National Assembly Library, and National Library of Korea. A total of forty two articles published between 1986 and 2009 were selected based on established inclusion criteria. RESULTS: Forty research papers were related to nursing, and there was only one research paper focused on elderly people with CAD. There were no papers using concept analysis, qualitative study, or randomized controlled clinical trial. Almost all definitions of adherence were adopted from outdated compliance definitions with the attribute of 'paternalistic obligation'. Measurement tools were not based on theoretical framework of adherence but borrowed from tools for measuring self-care, health behavior, or self-efficacy. Overall patient's adherence was analyzed in most studies, except for a few studies which focused on diet and exercise only. Educational strategy was the main strategy used in intervention studies. CONCLUSIONS: The concept of adherence and measurement tools need to be clarified, along with development of the specific adherence interventions according to the type of adherence in patients with CAD.

Background: Multimorbidity and suicide rates are on the rising among older Korean population. Recent studies have shown that multimorbidity is associated with increased suicidal ideation. Thus, this study was to investigate individual factors of suicidal ideation among older Korean adults with multimorbidity. Methods: A cross-sectional study was conducted using a subsample (n=20,533) with multimorbidity aged 65 over of the 2017 Korean community health survey. Binary logistic regression model assessed the association of physical activity, sitting times, self-reported sleep duration, and depression with suicidal ideation in older adults with multimorbidity. Results: Overall, 2,790 (13.6%) of the sample reported suicidal ideation within the past year. Logistic regression analysis showed that women, low monthly family income, low physical activity, long sitting times, inappropriate sleep duration and depression were significantly associated with increased risk of suicidal ideation in older adults with multimorbidity. Conclusions To reduce the rate of suicidal ideation in older adults with multimorbidity, healthcare providers should be aware of the importance on routine assessment for physical activities, sleep pattern, and mental status of older adults in clinical settings. Particularly, female and low-income older adults with multimorbidity should be prioritized for early detection and individualized suicide prevention based on our findings.

Background: The purpose of this study was to describe the distinct cognitive trajectories for 8 years according to living arrangement among community-dwelling older adults using the Korean longitudinal study of ageing. Methods: We analyzed data from a final sample of 3,049 community-dwelling older adults aged 65 years or older who participated in at least three cognitive function measures in an 8-year period (2012-2020). Cognitive function was assessed by Korean mini mental state examination. Latent class growth model analysis was applied to determine the number and shape of trajectories of older adults according to living arrangement.Multinomial logistic regression analysis was used to determine risk factors for cognitive function trajectories. Results: We identified five trajectory patterns in cognitive function among older adults living alone; ‘high-stable (35.6%)’, ‘high-declining (32.5%)’, ‘moderate-steep declining (6.2%)’, ‘low-stable (18.9%)’, and ‘low declining (6.8%)’. In older adults living with family, there were four trajectory patterns; ‘high-stable (46.4%)’, ‘high-declining (32.0%)’, ‘low-stable (15.9%)’, and ‘low-declining (5.7%)’. Age, instrumental activities of daily living, and depression were common factors of cognitive changes in both older adults living alone and those living with family members. However, monthly incomes was only associated with the risk of cognitive function in older adults living alone. Conclusions We found that cognitive function trajectories among older adults may differ depending on the type of living arrangement. Therefore, further studies and health policies are required for avoiding cognitive impairment by living arrangement among older adults based on the results of this study.

PURPOSE: The purpose of this study was to identify the levels of relocation stress syndrome (RSS) and influencing the stress experienced by Intensive Care Unit (ICU) patients just after transfer to general wards. METHODS: A cross-sectional study was conducted with 257 patients who transferred from the intensive care unit. Data were collected through self-report questionnaires from May to October, 2009. Data were analyzed using the Pearson correlation coefficient, t-test, one-way ANOVA, and stepwise multiple linear regression with SPSS/WIN 12.0. RESULTS: The mean score for RSS was 17.80+/-9.16. The factors predicting relocation stress syndrome were symptom experience, differences in scope and quality of care provided by ICU and ward nursing staffs, satisfaction with transfer process, length of stay in ICU and economic status, and these factors explained 40% of relocation stress syndrome (F=31.61, p<.001). CONCLUSION: By understanding the stress experienced by ICU patients, nurses are better able to provide psychological support and thus more holistic care to critically ill patients. Further research is needed to consider the impact of relocation stress syndrome on patients' health outcomes in the recovery trajectory.

BACKGROUND: Health illiteracy is a problem often unrecognized by health care providers. It influences medical costs and the health status of adults. The purposes of this study were to determine the level of health literacy in community-dwelling adults and to identify the factors influencing it. METHODS: A cross-sectional survey was conducted in Seoul, Gyeonggi and Chungcheong province. A total of 420 adults aged 18 or older were interviewed by trained nursing students between November 1 to December 30, 2011. Health literacy was measured using the Short Test of Functional Health Literacy in Adults. Data were analyzed using the PASW 18.0 program. RESULTS: The mean score of health literacy was 50.64+/-19.18. In the multiple linear regression analysis, health literacy was significantly associated with education (beta=0.17, P=0.001), alcohol use (beta=-0.12, P=0.010), and perceived health status (beta=0.11, P=0.029). These factors accounted for about 7% of health literacy. CONCLUSIONS: Health literacy is a very important public health issue. Our findings showed that educational level, alcohol use and perceived health status should be considered when assessing this issue in patients. Furthermore, the development of a standardized Korean assessment tool for health literacy and specified interventions for enhancing health literacy are needed to improve health outcomes.

PURPOSE: This study develop a Video Recording-Based Standardized Handoff (VRSH) program at shift change for ward nurses.METHOD: The study was conducted in five medical, three surgical, and one comprehensive nursing care service wards affiliated with a secondary general hospital. In this methodological study, the VRSH program was developed between April and December, 2017. It is noted that 65 nurses who were involved in the VRSH program participated in this study.RESULTS: In line with the modified Situation, Background, Assessment, Recommendation tool, the VRSH program consisted of three phases. In the VRSH program, the average time for handoff duration was 3–5 minutes per patient. More than 90% of the ward nurses were satisfied with the VRSH program since it benefited them by reducing overtime work and improving the performance, as well as effective communication, of nurses. The content analysis of nurses' VRSH program experience, revealed three categories and eight sub-categories.CONCLUSION: This study provides evidence that the VRSH program improves effective nursing performance and, the handoff communication and relationships between nurses. Future studies on large sample sizes and multiple settings are required to substantially evaluate the impact of the VRSH program on clinical outcomes.

Background: This study aimed to identify factors influencing dementia-screening behaviors among community-dwelling middle-aged and older adults using the Korean Community Health Survey data in 2018. Methods: This cross-sectional study included community-dwelling adults aged ≥50 years. We used data related to socio-demographic and health-related factors and subjective cognitive function. We conducted a chi-squared test and multiple logistic regression analysis with weighted analysis. Results: Of 108,050 participants (men, 46.6%; ≥65 years old, 41.5%), only 13.4% (20,404 participants) performed dementia-screening. Using multiple logistic regression, we found that advanced age, female, and unemployed, having a low level of education, low monthly family income, and rural residence, no alcohol intake, no-smoking, hypertension, cognitive dysfunction, and awareness of the dementia helpline service center were positively associated with dementia-screening behaviors. Conclusions This study suggests the application of holistic approaches to improve dementia-screening behaviors among middle-aged and older adults considering their socioeconomic and health related conditions. Our findings highlight that government health programs should consider socio-economic status and awareness of dementia helpline services in designing dementia prevention programs.

PURPOSE: We investigated the factors influencing the time to reach full enteral feeding in very low birth weight infants. We compared the days of life to start tube or oral feeding, to regain birth weight, and to establish full enteral feeding in very low birth weight infants and determined the risk factors delaying full enteral feeding. METHODS: We reviewed the medical records of 214 newborn infants less than 1,500 g at birth, who were delivered at Chonnam National University Hospital from January 1, 1997 to May 31, 2000. These infants were divided into three groups by birth weight (less than 1,000 g, 1,000-1,249 g, and 1,250-1,499 g). Gestational age, birth weight, the days of life to start first tube or oral feeding, to regain bith weight and to reach full enteral feeding, and the possible risk factors delaying the progress of enteral feeding were analyzed. RESULTS: The gestational age was 29.69+/-2.33 weeks and the birth weight was 1,212+/-194.3 g. The time to start tube or oral feeding, to regain birth weight, and to establish full enteral feeding were significantly later and longer in the lower birth weight group. The time to reach full enteral feeding was related to the duration of mechanical ventilation and oxygen therapy, and was significantly longer in the infants with severe respiratory distress syndrome (RDS), chronic lung disease (CLD), apnea, intraventricular hemorrhage (IVH), cystic periventricular leukomalacia, sepsis/disseminated intravascular coagulopathy, ricketts, and total parenteral nutrition. CONCLUSION: The time to reach full enteral feeding was inversely related to the birth weight, and the risk factors for delayed full enteral feeding were the presence and/or the severity of diseases related to the prematurity such as the duration of mechanical ventilation and oxygen therapy, RDS, CLD, apnea, IVH, and sepsis.

BACKGROUND: A conventional treadmill provides manually controlled constant speed during exercise. A fast interactive automatic speed control treadmill (FAST), which is highly sensitive to the position of the user on the belt and spontaneously adjusts its speed accordingly, was evaluated in terms of energy expenditure (EE) during exercise. METHODS: A total of 43 subjects were recruited and assigned to one of three exercise intensity groups-low (LIG; 40-50% of VO2max), moderate (MIG; 55-65% of VO2max), and high (HIG; 70-80% of VO2max). During the first test (Test-1), each subject performed an exercise bout on the FAST while spontaneously changing their locomotion speed within their assigned range of intensity. The average speed in Test-1 was calculated and applied to the second test (Test-2), in which the subjects exercised at a constant belt speed and matched the total travel distance of Test-1. During the tests, the oxygen uptake (VO2), heart rate (HR), respiratory quotient (RQ), oxygen pulse (OP), and EE of each subject were measured. RESULTS: The average VO2 in Test-1 was higher than that in Test-2 for both the LIG (22.95+/-2.55 vs. 21.72+/-2.90 ml/kg/min) and MIG (31.17+/-3.75 vs. 29.73+/-4.86 mL/kg/min) (P<.05) subjects. The EE in Test-1 was higher than that in Test-2 for both the LIG (7.09+/-1.67 vs. 6.71+/-1.73 kcal/min) and MIG (9.79+/-2.62 vs. 9.32+/-2.71 kcal/min) (P<.05) subjects. The HR, RQ, and OP in the LIG and the MIG were similar. There was no difference between Test-1 and Test-2 in any of the metabolic parameters for the HIG subjects. CONCLUSIONS: The results indicated that, low- to moderate-intensity treadmill exercise at varying speeds required higher energy expenditure than that at a constant speed. Thus, a treadmill with a spontaneous speed variation function may be an effective exercise modality that increases energy expenditure.
