Social determinants of health and emergency department visits among older adults with multimorbidity: insight from 2010 to 2018 National Health Interview Survey.

BACKGROUND: Multimorbidity is prevalent among older adults and is associated with adverse health outcomes, including high emergency department (ED) utilization. Social determinants of health (SDoH) are associated with many health outcomes, but the association between SDoH and ED visits among older adults with multimorbidity has received limited attention. This study aimed to examine the association between SDoH and ED visits among older adults with multimorbidity. METHODS: A cross-sectional analysis was conducted among 28,917 adults aged 50 years and older from the 2010 to 2018 National Health Interview Survey. Multimorbidity was defined as the presence of two or more self-reported diseases among 10 common chronic conditions, including diabetes, hypertension, asthma, stroke, cancer, arthritis, chronic obstructive pulmonary disease, and heart, kidney, and liver diseases. The SDoH assessed included race/ethnicity, education level, poverty income ratio, marital status, employment status, insurance status, region of residence, and having a usual place for medical care. Logistic regression models were used to examine the association between SDoH and one or more ED visits. RESULTS: Participants' mean (± SD) age was 68.04 (± 10.66) years, and 56.82% were female. After adjusting for age, sex, and the number of chronic conditions in the logistic regression model, high school or less education (adjusted odds ratio [AOR]: 1.10, 95% confidence interval [CI]: 1.02-1.19), poverty income ratio below the federal poverty level (AOR: 1.44, 95% CI: 1.31-1.59), unmarried (AOR: 1.19, 95% CI: 1.11-1.28), unemployed status (AOR: 1.33, 95% CI: 1.23-1.44), and having a usual place for medical care (AOR: 1.46, 95% CI 1.18-1.80) was significantly associated with having one or more ED visits. Non-Hispanic Black individuals had higher odds (AOR: 1.28, 95% CI: 1.19-1.38), while non-Hispanic Asian individuals had lower odds (AOR: 0.71, 95% CI: 0.59-0.86) of one or more ED visits than non-Hispanic White individuals. CONCLUSION: SDoH factors are associated with ED visits among older adults with multimorbidity. Systematic multidisciplinary team approaches are needed to address social disparities affecting not only multimorbidity prevalence but also health-seeking behaviors and emergent healthcare access.

Life-Sustaining Treatment Decision in Palliative Care Based on Electronic Health Records Analysis.

AIMS AND OBJECTIVES: This study sought to explore the present status of life-sustaining treatment decisions in a tertiary hospital to improve the life-sustaining treatment decision-making process. BACKGROUND: Life-sustaining treatment decisions are crucial for palliative care because they encompass decisions to withdraw treatments when patients cannot articulate their values and preferences. However, surrogate decisions have settled many life-sustaining treatment cases in South Korea, and this trend is prevalent. DESIGN: We conducted a retrospective, descriptive study employing a review of electronic health records. METHODS: We extracted and analysed electronic health records of a tertiary hospital. Our inclusion criteria included adult patients who completed life-sustaining treatment forms in 2019. A total of 2,721 patients were included in the analysis. We analysed the decision-maker, the timing of the decision, and patients' health status a week before the decision. We followed the STROBE checklist. RESULTS: Among 1,429 deceased patients, those whose families had made life-sustaining treatment decisions totalled 1,028 (70.6%). The median interval between life-sustaining treatment documentation completion to death was three days, more specifically, two days in the family decision group and 5.5 days in the patient decision group. As the decision day neared, there were marked changes in patients' vital signs and laboratory test results, and the need for nursing care increased. CONCLUSIONS: Life-sustaining treatment decisions were made when death was imminent, suggesting that the time required to discuss end-of-life care was generally insufficient among patients, family, and healthcare professionals in Korea. RELEVANCE TO CLINICAL PRACTICE: Monitoring changes in laboratory test results and symptoms could help screen the patients who need the life-sustaining treatment discussion. As improving the quality of death is imperative in palliative care, institutional efforts, such as clinical ethics support services, are necessary to improve the life-sustaining treatment decision-making process for patients, families, and healthcare providers.

Risk factors for heel pressure injury in cardiovascular intensive care unit patients.

This study analyzed the risk factors for heel pressure injury in cardiovascular intensive care unit patients with the aim of laying the groundwork for preventive nursing interventions. We conducted a retrospective case-control study of 92 patients who were admitted to the cardiovascular surgical or medical intensive care unit of a university hospital in South Korea between January and December 2017. Of these patients, 31 and 61 were included to the heel pressure injury group and the non-heel pressure injury group, respectively. Data on their demographic, disease-related, and intensive care unit treatment characteristics, as well as the degree of pressure injury, were collected from the hospital's electronic medical records using a standardized form. Cardiac surgery (P < .001), operation time (P = .001), use of a mechanical ventilator (P < .001), use of vasoconstrictors (P < .001), use of sedative drugs (P < .001), and extracorporeal membrane oxygenation treatment (P < .001) were identified as significant risk factors for heel pressure injury. A total of 22 patients (71%) from the heel pressure injury group developed deep tissue injury, and 16 patients (51.6%) who received extracorporeal membrane oxygenation treatment developed heel pressure injury.

Nurses' ethical decision-making during end of life care in South Korea: a cross-sectional descriptive survey.

BACKGROUND: Although nurses are crucial to ensure patients' peaceful death in hospitals, many nurses experience various ethical conflicts during end-of-life care. Therefore, research on nurses' entire ethical decision-making process is required to improve nurses' ethical decision-making in end-of-life care. This study aimed to identify Korean nurses' ethical decision-making process based on their moral sensitivity to end-of-life patients. METHODS: In total, 171 nurses caring for terminal patients responded to the survey questionnaire. To measure the participants' moral sensitivity and ethical decision-making process, we used the Korean version of the Moral Sensitivity Questionnaire and Nurses' Ethical Decision-Making around End of Life Care Scale. Finally, multiple linear regression analysis was used to investigate the effect of moral sensitivity on nurses' ethical decision-making. RESULTS: The mean of moral sensitivity was 4.8 ± 0.5 (out of 7), and that of ethical decision-making was 4.6 ± 0.5 (out of 6). Among the sub-dimensions of ethical decision-making, the highest score was in perceived professional accountability (5.2 ± 0.5), and the lowest in moral reasoning and moral agency (3.9 ± 0.6); the score of moral practice was 4.4 ± 0.7. In the multiple linear regression model, moral sensitivity (ß = 0.852, p < .001), clinical department (ß = - 7.018, p = .035), ethics education (ß = 20.450, p < .001), job satisfaction (ß = 5.273, p < .001), and ethical conflict (ß = - 2.260, p = 0.031) were influential ethical decision-making factors. CONCLUSIONS: This study revealed a gap between nurses' thoughts and practices through the ethical decision-making process. They failed to lead their thought to moral practice. It also implies that moral sensitivity could positively affect nurses' ethical decision-making. To make nurses morally sensitive, exposing them to various clinical cases would be helpful. Additionally, ethics education and clinical ethics supporting services are valuable for improving nurses' ethical decision-making. If nurses improved their ethical decision-making regarding end-of-life care, their patients could experience a better quality of death.

Secondary traumatic stress and compassion satisfaction mediate the association between stress and burnout among Korean hospital nurses: a cross-sectional study.

BACKGROUND: Burnout among nurses is a worldwide public health epidemic that adversely affects nurses' quality of life as well as the patient's outcomes. The aim of this study was to evaluate the influence of stress on nurses' burnout and to identify the mediating effects of secondary traumatic stress and compassion satisfaction among clinical nurses in South Korea. METHODS: A quantitative, cross-sectional study evaluated the survey data from 10,305 female registered hospital nurses who participated in the Korea Nurses' Health Study (KNHS) Module 5. The survey included a demographic questionnaire and the Professional Quality of Life version 5 (ProQOL 5). Bootstrap analyses (using the PROCESS macro) were employed to evaluate the mediating effect between variables. RESULTS: Stress was significantly associated with burnout and mediated by secondary traumatic stress and compassion satisfaction (ßindirect 1 = 0.185, Bootstrap confidence interval (BS CI) [0.175, 0.194]; ßindirect 2 = 0.226, BS CI [0.212, 0.241], respectively). In addition, the magnitude of the indirect effects of compassion satisfaction was significantly greater than the magnitude of the indirect effects of secondary traumatic stress (ßindirect 1-ßindirect 2 = - 0.042, BS CI [- 0.058, - 0.026]). The findings of this study indicate that the positive aspect (compassion satisfaction) of work experiences can offset the negative aspects (secondary traumatic stress), consequently reducing burnout level. CONCLUSIONS: Our study findings suggest that a multidimensional approach to assessing nurse burnout and implementation of proper management will improve quality of life for nurses and help maintain positive attitudes and quality of patient care.

Heterogeneity in the Prevalence of Cardiovascular Risk Factors by Ethnicity and Birthplace Among Asian Subgroups: Evidence From the 2010 to 2018 National Health Interview Survey.

BACKGROUND: Asian people in the United States have different sociodemographic and health-related characteristics that might affect cardiovascular disease (CVD) risk by ethnicity and birthplace. However, they are often studied as a monolithic group in health care research. This study aimed to examine heterogeneity in CVD risk factors on the basis of birthplace among the 3 largest Asian subgroups (Chinese, Asian Indian, and Filipino) compared with US-born non-Hispanic White (NHW) adults. METHODS AND RESULTS: A cross-sectional analysis was conducted using the 2010 to 2018 National Health Interview Survey data from 125 008 US-born and foreign-born Chinese, Asian Indian, Filipino, and US-born NHW adults. Generalized linear models with Poisson distribution were used to examine the prevalence and prevalence ratios of self-reported hypertension, diabetes, high cholesterol, physical inactivity, smoking, and overweight/obesity among Asian subgroups compared with US-born NHW adults. The study included 118 979 US-born NHW and 6029 Asian adults who self-identified as Chinese (29%), Asian Indian (33%), and Filipino (38%). Participants' mean (±SD) age was 49±0.1 years, and 53% were females. In an adjusted analysis, foreign-born Asian Indians had significantly higher prevalence of diabetes, physical inactivity, and overweight/obesity; foreign-born Chinese had higher prevalence of physical inactivity, and foreign-born Filipinos had higher prevalence of all 5 CVD risk factors except smoking compared with NHW adults. CONCLUSIONS: This study revealed significant heterogeneity in the prevalence of CVD risk factors among Asian subgroups by ethnicity and birthplace, stressing the necessity of disaggregating Asian subgroup data. Providers should consider this heterogeneity in CVD risk factors and establish tailored CVD prevention plans for Asian subgroups.

The effects of a 24-week interactive text message-based mobile health intervention for enhancing self-care behaviours of patients with heart failure: A quasi-experimental study.

AIMS: The aim of this study was to identify the effects of a 24-week interactive text message-based mobile health intervention (called) on enhancing the self-care behaviours of patients with heart failure. BACKGROUND: Whether text message-based mobile health intervention can be used to improve long-term adherence to self-care behaviours among heart failure patients remains unclear. DESIGN: A quasi-experimental study with a pretest-post-test design and repeated measures. METHODS: Data from 100 patients (mean age, 58.78 years; 83.0% men) were analysed. The intervention group (n = 50) used the program over 24 weeks, which consisted of weekly goal setting and interactive text messaging, while the control group (n = 50) received usual care. Trained research assistants collected data using self-reported Likert questionnaires. Primary (self-care behaviours) and secondary (health literacy, eHealth literacy, and disease knowledge) outcome variables were measured at baseline and at 1, 3 and 6 months after intervention for follow-up. RESULTS: The findings showed that the intervention group demonstrated significantly better self-care behaviours than the control group during the 6 months. Notably, the trajectory of self-care behaviours of the patients in the intervention group showed a steep rise between the first- and third-month follow-up, followed by high stability between the third- and sixth-month follow-up. In addition, the intervention group had significantly higher disease knowledge than the control group at the first- and sixth-month follow-up. CONCLUSIONS: We found that the program, as an interactive text messaging service, may be an optimal strategy for improving long-term adherence to self-care behaviours through motivating and providing social support. RELEVANCE TO THE NURSING PRACTICE: The WithUs program can help nurses and other healthcare professionals to track patients' health indicators such as symptom severity, diet and physical activity. In addition, nurses can take an important role in evaluating the efficacy of the app in relation to patients' health outcome. PATIENT OR PUBLIC CONTRIBUTION: Patients have completed a self-reported questionnaire after providing informed consent.

Preoperative frailty based on laboratory data and postoperative health outcomes in patients undergoing coronary artery bypass graft surgery.

BACKGROUND: Frailty is associated with adverse surgical outcomes. Patients with cardiovascular diseases have many risk factors of frailty; thus, preoperative frailty evaluation is necessary to predict adverse outcomes after coronary artery bypass graft (CABG) surgery. Laboratory data based-frailty assessments are objective and not time-consuming, addressing the need for an accurate but simple frailty screening for patients awaiting CABG surgery. OBJECTIVES: This retrospective study aimed to determine the association between laboratory based-frailty and patient health outcomes after CABG surgery. METHODS: We evaluated 896 patients who underwent on-pump or off-pump CABG surgery between August 1, 2015 and July 31, 2020 at a tertiary hospital. The frailty index-laboratory (FI-LAB), which comprises 32 laboratory parameters and vital signs, was used for frailty assessment. RESULTS: The patients were divided into three groups according to their preoperative FI-LAB level as low (FI-LAB <0.25, 23.0%), moderate (FI-LAB ≥0.25 to ≤0.4, 54.9%), and high (FI-LAB>0.4, 22.1%) frailty groups. In the confounder-adjusted analysis, the lengths of hospital stay and intensive care unit stay were longer by 2.20 days (p=.023) and by 0.89 days (p=.009), respectively, in the high frailty group than those in the low frailty group. The odds ratio for 30-day readmission was also 2.58 times higher in the high frailty group than that in the low frailty group. CONCLUSION: A high preoperative FI-LAB score indicates increasing risks of adverse postoperative outcomes among CABG surgery patients. FI-LAB has potential strengths to capture the need for a more thorough frailty assessment for cardiac surgery patients.

Frailty assessment using routine clinical data: An integrative review.

BACKGROUND: Frailty is a common but complex problem in older adults. Frailty assessment using routine clinical data has been suggested as a pragmatic approach based on electronic health records from primary care center or hospital settings. PURPOSE: We aimed to explore the tools and outcome variables used in the published studies on frailty assessment using routine clinical data. METHODS: An integrative literature review was conducted using the method of Whittemore and Knafl. A literature search was conducted in PubMed, EMBASE, and CINAHL from January 2010 to October 2021. RESULTS: A total of 45 studies and thirteen frailty assessment tools were analyzed. The assessment items were generally biased toward frailty's risk factors rather than the mechanisms or phenotypes of frailty. Similar to using conventional tools, routine clinical data-based frailty was associated with adverse health outcomes. CONCLUSIONS: Frailty assessment based on routine clinical data could efficiently evaluate frailty using electronic health records from primary care centers or hospitals. However, they need refinement to consider the risk factors, mechanisms, and frailty phenotypes.

Frailty and its associated factors among older adults with cancer undergoing chemotherapy as outpatients: A cross-sectional study.

PURPOSE: Frailty can affect cancer treatment decisions and outcomes. Depression, fatigue, and cognitive impairment often experienced by patients with cancer are expected to be associated with frailty. We aimed to identify frailty and its related factors in older adults with cancer undergoing chemotherapy. METHODS: We conducted a cross-sectional descriptive study in a Korean urban tertiary hospital. A structured self-report questionnaire was used including frailty and its related variables and measured heart rate variability (HRV). Multinomial logistic regression was performed to identify the factors related to frailty. RESULTS: Data from 124 out of 136 patients with stomach, colorectal, and lung cancers were analyzed. Approximately 90% of the participants were in the pre-frail and frail groups. There were significant differences among the three groups in terms of depression (p = 0.006) and HRV (p = 0.041). The factor associated with higher frailty levels was depression across groups (pre-frail odds ratio (OR): 1.31, 95% CI: 1.14-1.51; frail OR: 1.29, 95% CI: 1.11-1.49). However, only deficits observed or commented on by others were retained as factors significantly associated with higher frailty in the pre-frail group (OR: 2.40, 95% CI: 1.40-4.13). In contrast, increased HRV (OR: 0.35, 95% CI: 0.13-0.95) was associated with lower frailty levels in the frail group. CONCLUSION: It is important to classify older adult patients with cancer into pre-frail and frail groups so that interventions can be provided on time. Understanding the characteristics associated with frailty in older adult patients with cancer can positively affect their health-related quality of life and treatment outcomes.

Cancer treatment-related cardiac dysfunction in breast cancer survivors: A retrospective descriptive study using electronic health records from a Korean tertiary hospital.

PURPOSE: The population overlap of breast cancer and cardiovascular diseases (CVDs) has increased due to early breast cancer detection and treatment and aging population trends. Moreover, breast cancer patients are at an increased risk for CVDs consequent to cancer treatments. We aimed to understand the characteristics of breast cancer patients with pre-existing CVDs and of those diagnosed with CVDs after receiving chemotherapy, and cancer treatment-related cardiac dysfunction's occurrence among Korean breast cancer patients with CVDs. METHODS: This retrospective descriptive study, which collected clinical data from electronic health records from a Korean tertiary hospital, included 1200 female breast cancer patients with CVDs, aged 15-75 years. RESULTS: A total of 45.7% had pre-existing CVDs, and 91.6% were classified as very high-risk for cardiotoxicity in the pre-existing CVDs group. Among the 1200 breast cancer patients with CVDs, only 439 patients had left ventricular ejection fraction (LVEF) data during their cancer treatment, and 121 received baseline assessment for LVEF. Of the 439 patients with LVEF data, 134 patients have been classified into cancer treatment-related cardiac dysfunction (CTRCD), and the median period from cancer diagnosis to CTRCD occurrence was 26.5 months. CONCLUSION: Despite the high cardiotoxicity risk of breast cancer patients with pre-existing CVDs, baseline studies of the risk assessment before chemotherapy were insufficient to support the prevention and early detection of cardiotoxicity. Therefore, it is paramount to consider how nurses focus on risk stratification before chemotherapy and support the regular monitoring of breast cancer survivors' cardiac functioning, to maintain optimal health status.
